Good afternoon，ladies and gentlemen!

I’m very honored to stand here and give you a short speech!To begin with ,I want to ask a question.Does everybody dream a good dream last night? Actually ,today I want to talk about dream with you.Of course, What I want to talk is not a dream you have last night,but a dream about life.Everyone has dreams about life, different dreams at different life stage,and we need dreams to support us.Dreams are like the stars we never reach in the sky,but like most mariners(水手),we can chart our course by them.With the dream,we have a direction,with a direction, we were no longer confused.With the dream, there is hope,With hope, we have the strength to fight.But I know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead.Young!Fortunately, I am young now.Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way.I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses.If no people believe you, you can make it to prove that you are right.If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.“My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains.” At some time in the past I also had am bitious words and I had some achievements.Each achievement results from my hard work.I always believe that “If you want to have more achievements than others, you must work harder.”

In some extent, the dream is the hope.If you can insist on doing something, the victory will come.Hold fast to dreams, for if dreams die, life is a brokenwinged bird that cannot fly.Hold fast to dreams, for when dreams go, life is a barren field frozen with snow.So my dear friends, think of your old and maybe dead dreams.Whatever it is, pick it up and make it alive from today.Let's move out!

Soy food good for women

Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report.And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.The studies add to a growing body of evidence about the role of diet in cancer.Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise.The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent.It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects.A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme.COX-2 affects inflammation, which may play a role in tumour growth.據(jù)美國(guó)研究人員報(bào)告，兒童時(shí)期經(jīng)常吃豆類(lèi)食品的女性患乳腺癌的風(fēng)險(xiǎn)較小。另一組研究人員則向美國(guó)癌癥研究協(xié)會(huì)提出，一周吃幾次魚(yú)的男性患結(jié)腸癌的幾率較小。

這兩項(xiàng)研究進(jìn)一步證明了飲食對(duì)于防癌的作用。癌癥防治專(zhuān)家認(rèn)為，在所有種類(lèi)的癌癥中，多達(dá)三分之二都是由吸煙、節(jié)食及缺乏鍛煉等不健康的生活方式造成的。

美國(guó)全國(guó)癌癥研究所和夏威夷大學(xué)的研究人員發(fā)現(xiàn)，在5歲至11歲時(shí)經(jīng)常吃豆腐、味噌等豆類(lèi)食品的女性患乳腺癌的幾率要低58%。至于豆類(lèi)食品為什么可以防癌還不清楚，不過(guò)大豆中所含的名叫異黃酮的化合物具有雌性激素的作用。

另一項(xiàng)研究表明，一周吃魚(yú)至少五次的男性患結(jié)腸癌的風(fēng)險(xiǎn)要比那些一周都吃不到一次魚(yú)的男性低40%。

很多魚(yú)類(lèi)中所富含的Omega-3脂肪酸能夠抑制環(huán)氧化酶2的活性。環(huán)氧化酶2會(huì)引起發(fā)炎，這可能會(huì)刺激腫瘤的生長(zhǎng)。

If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do.The findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life.Reporting in the journal Neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link.But it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain.The study compared mental abilities to body mass index(BMI), a

measurement of weight in relation to height used to define overweight and obesity.A BMI of 25 or more indicates overweight, and 30 or more is obese.The study also investigated the relationships between BMI and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in France through the use of four cognitive tests.The study found a higher BMI was associated with lower cognitive test scores.Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words.研究人員提醒，如果你已步入中年，發(fā)現(xiàn)自己的記憶力不如從前，那么你得小心體重了。研究表明，超重的人記憶測(cè)試的得分要比較瘦的人低。

研究發(fā)現(xiàn)，體重偏大的中年人今后患老年癡呆癥的可能性較大。

研究報(bào)告在《神經(jīng)學(xué)》期刊上發(fā)表，研究人員推斷，心血管疾病及糖尿病的高發(fā)現(xiàn)象可以解釋其中的原因。此外，脂肪細(xì)胞所產(chǎn)生的物質(zhì)，如瘦體激素，對(duì)大腦有直接影響。

此項(xiàng)研究將調(diào)查對(duì)象的智力與體重指數(shù)進(jìn)行了對(duì)比。體重指數(shù)指的是身高和體重之間的比例，主要用來(lái)衡量一個(gè)人是否偏胖或肥胖。體重指數(shù)為25或25以上的人偏胖，達(dá)到30或30以上的人則為肥胖。

研究人員還對(duì)體重指數(shù)和認(rèn)知功能間的關(guān)系進(jìn)行了研究，他們?cè)诜▏?guó)對(duì)2223位年齡在32歲至62歲間的健康男女進(jìn)行了認(rèn)知測(cè)試。

研究發(fā)現(xiàn)，體重指數(shù)越大，認(rèn)知測(cè)試的得分越低。其中一項(xiàng)“單詞記憶”的測(cè)試結(jié)果表明，在16個(gè)單詞中，體重指數(shù)為20的人平均能記住9個(gè)，而體重指數(shù)為30的人平均只能記住7個(gè)。

People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released Monday.Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.A 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of

Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.“A third of the population of the UK and over 40 percent in the US regularly sleep less than five hours a night, so it is not a trivial problem,” he told reporters.Previous research has highlighted the potential health risks of shift work and disrupted sleep.But the study by Cappuccio and colleagues, which was

supported by British government and US funding, is the first to link duration of sleep and mortality rates.The study looked at sleep patterns of participants aged 35-55 at two points in their livesand then tracked their mortality rates until 2004.The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.“In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health,” he said.(Agencies)本周一公布的一項(xiàng)大規(guī)模英國(guó)調(diào)查表明，睡眠不足的人死于心臟病的幾率是睡眠充足者的兩倍多。

目前其中的原因尚不清楚，但研究人員稱(chēng)，睡眠不足會(huì)導(dǎo)致血壓升高，從而增大患心臟病和中風(fēng)的風(fēng)險(xiǎn)。

一項(xiàng)針對(duì)1萬(wàn)名政府職員、長(zhǎng)達(dá)17年的跟蹤調(diào)查表明，每晚睡眠時(shí)間從七個(gè)小時(shí)減少到五個(gè)小時(shí)或更少的人因各種原因而死亡的幾率是睡眠正常者的1.7倍，而且死于心血管疾病的風(fēng)險(xiǎn)也增加了1倍多。

沃里克大學(xué)醫(yī)學(xué)院的心血管藥物學(xué)教授弗朗西斯哥?卡普西奧在英國(guó)睡眠學(xué)會(huì)在劍橋召開(kāi)的一年一度的研討會(huì)上說(shuō)，這一研究成果揭示了忙碌的現(xiàn)代生活中潛在的危險(xiǎn)。

他在接受記者采訪時(shí)說(shuō)：“三分之一的英國(guó)人以及超過(guò)40%的美國(guó)人每晚的睡眠時(shí)間常常達(dá)不到五個(gè)小時(shí)，所以這個(gè)問(wèn)題不可小視。”

此前有調(diào)查發(fā)現(xiàn)輪班及睡眠中斷會(huì)對(duì)健康產(chǎn)生潛在威脅。但卡普西奧及其同事的這項(xiàng)調(diào)查則首次揭示了睡眠時(shí)間長(zhǎng)短與死亡率之間的關(guān)系。該調(diào)查由英國(guó)政府和美國(guó)基金提供資助。

該調(diào)查對(duì)年齡在35歲至55歲之間的人在1985年至1988年以及1992年至1993年兩個(gè)階段的睡眠模式進(jìn)行了探究，并對(duì)這一人群截至2004年的死亡率進(jìn)行了追蹤。

調(diào)查還考慮到了調(diào)查對(duì)象的初始年齡、性別、是否吸煙喝酒、體重指數(shù)、血壓及膽固醇指標(biāo)等其它可能的風(fēng)險(xiǎn)因素。

卡普西奧說(shuō)，睡眠時(shí)間過(guò)長(zhǎng)也可能導(dǎo)致如抑郁癥及癌因性疲乏等其它健康問(wèn)題。

他說(shuō)：“就預(yù)防而言，我們的研究結(jié)果表明，每晚睡眠時(shí)間持續(xù)保持在七小時(shí)左右最益于身體健康。”

my chinese dream 我的中國(guó)夢(mèng)

i am very glad to stand here to give thier a short speech.today my topic is that the youth are the future of motherland 很高興站在這里做這篇短小的演講，我演講的主題是青年是祖國(guó)的未來(lái)。

在準(zhǔn)備英語(yǔ)演講比賽的時(shí)候，我本想簡(jiǎn)單地從網(wǎng)上搜索一些文章作為我演講的內(nèi)容。我看過(guò)很多文章，有著名主持人的、北大教授的、大學(xué)生的，也有初中生的。但是看完之后，我放棄了當(dāng)初的想法，我甚至為當(dāng)初的想法感到有一些羞愧。因?yàn)榻裉煳艺驹谶@里向大家演講的主題，是一個(gè)莊重而嚴(yán)肅的主題；是一個(gè)充滿榮耀與自豪的主題；是每一個(gè)中華兒女共同期盼的主題。每個(gè)人都有屬于他們自己的中國(guó)夢(mèng)，而我，當(dāng)然也有一直縈繞在心懷只屬于我的中國(guó)夢(mèng)。

so what?s my chinese dream ? finally i will announce.we had learned a lot of knowledge and understood a lot of truth in the book.we had a basic concept to our country at that time.we know that our country is full of sunshine , and we are the future of our country, and our dreams are to be the hope of our motherland.我的中國(guó)夢(mèng)是什么樣的？先賣(mài)個(gè)關(guān)子。

記得剛剛上學(xué)那會(huì)兒，我們天真無(wú)邪。在課本里，我們學(xué)到了很多很多知識(shí)，也明白了很多很多道理，我們對(duì)祖國(guó)也有了一個(gè)最基本的概念。我們知道我們的祖國(guó)到處充滿陽(yáng)光，正在慢慢發(fā)展，而我們，就是祖國(guó)未來(lái)的花朵，未來(lái)的希望。我們夢(mèng)想將來(lái)能夠成為祖國(guó)的希望。

這，是我們最初的中國(guó)夢(mèng)。最真誠(chéng)的我們，最真誠(chéng)的夢(mèng)。

但是，不知道什么時(shí)候開(kāi)始，我們長(zhǎng)大了，生活似乎一下子變得和以前不太一樣了，與此同時(shí)，雖然我們很不想承認(rèn)但是卻又不得不承認(rèn)的是，我們的思想，我們的為人處世觀，我們對(duì)我們祖國(guó)的看法，也潛移默化中慢慢開(kāi)始了轉(zhuǎn)變。我們的社會(huì)變得到處充滿欺騙、冷漠、勾心斗角、壓力、腐敗、險(xiǎn)惡，我們變得暴躁，不冷靜，憤世嫉俗。我們的國(guó)家，似乎也開(kāi)始變得千瘡百孔。而好多我們親愛(ài)的祖國(guó)委以重任培養(yǎng)的青年學(xué)生們變得輕浮、急躁，更別提什么夢(mèng)想，什么中國(guó)夢(mèng)了？

are we sick, or is our dear motherland sick? 我很驚訝，當(dāng)大街上有老人摔倒，我們不敢再去扶起；我很難過(guò)，當(dāng)有人做了好事被報(bào)道，更多的人說(shuō)他做作；我很傷心，當(dāng)我看到我們眾多的青年人變得冷漠、市儈、欺詐以及缺乏理想。

到底是我們病了，還是我們親愛(ài)的祖國(guó)病了？

i dont want to talk about the construction of our country politics, and also speak impassioned speech on the diaoyu island event.i just want to appeal young people,showing the side of youth,good and confidence.we must learn to organize our own thoughts, correct our own concept, and change our direction to the right side in future life.china dream actually lies in our young generation, especially of the intellectuals.我的中國(guó)夢(mèng)，不想大談?wù)危膊幌雽?duì)釣魚(yú)島事件發(fā)表慷慨激昂的演講。我只想呼吁，呼吁我們年輕人，呼吁我們祖國(guó)的希望能夠?qū)⑽覀兊那啻阂幻妫瑢⑽覀兊纳屏家幻妫瑢⑽覀兊淖孕乓幻婧煤谜宫F(xiàn)出來(lái)。我們要學(xué)會(huì)整理自己的思想，端正自己看問(wèn)題的觀念，擺正自己的人生方向。我們的中國(guó)夢(mèng)實(shí)際上正掌握在我們自己手上，掌握在我們年青一代，尤其是知識(shí)分子手上。

也許，一個(gè)人，是渺小的；但是當(dāng)他和祖國(guó)聯(lián)系起來(lái)時(shí)，就是偉大的。也許，一個(gè)夢(mèng)想，是渺小的，但是當(dāng)它成為祖國(guó)的夢(mèng)想時(shí)，就是不可估量的。也許，我無(wú)法用自己一個(gè)人的力量撬起整個(gè)中國(guó)，但是我們千千萬(wàn)萬(wàn)年輕人一起為祖國(guó)的夢(mèng)想去奮斗時(shí)，我們的祖國(guó)就足以令世界顫抖、動(dòng)容。i dream to construct our beauty china with millions of young people who have the same dream.we do it without exaggeration but only with persistence.我夢(mèng)想和萬(wàn)千具有相同夢(mèng)想的年輕人去建設(shè)我們的美麗中國(guó)，沒(méi)有虛浮，只有執(zhí)著，只有奮斗，只有勇于擔(dān)當(dāng)。這就是我的中國(guó)夢(mèng)！

that is my speech,thanks everyone.我的演講就到這里，謝謝大家。

we are the world ,we are the future 世界是我們的，未來(lái)是我們的

someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”.i don?t know who wrote these words, but i?ve always liked them as a reminder that the future can be anything we want it to be.we are all in the position of the farmers.if we plant a good seed ,we reap a good harvest.if we plant nothing at all, we harvest nothing at all.一些人說(shuō)?我們正在讀一本無(wú)窮的書(shū)中的第一章的第一節(jié)。?我不知道誰(shuí)寫(xiě)了這些話，但是我一直很喜歡它，因?yàn)樗嵝蚜宋遥覀兡軌騽?chuàng)造我們想要的未來(lái)。

we are young.“how to spend the youth?” it is a meaningful question.to answer it, first i have to ask “what do you understand by the word youth?” youth is not a time of life, it?s a state of mind.it?s not a matter of rosy cheeks, red lips or supple knees.it?s the matter of the will.it?s the freshness of the deep spring of life.我們都是農(nóng)夫。如果我們播下好的種子，我們將會(huì)豐收。如果我們的種子很差，有很多草籽，收割的將是無(wú)用的莊稼。如果我們什么也不播種，什么收獲也沒(méi)有。

youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease.this often exists in a man of 60 more than a boy of 20.nobody grows old merely by a number of years.we grow old by deserting our ideals.years wrinkle the skin , but to give up enthusiasm wrinkles the soul.worry , fear , self –distrust bows the heart and turns the spirit back to dust.我們是年輕的。?怎樣度過(guò)青春??這是個(gè)有意義的問(wèn)題。為了去回答它，我首先要問(wèn)?從‘青春’這個(gè)詞中你能理解到什么?? 青春不是人生的一個(gè)時(shí)期，而是精神的一種狀態(tài)。青春不是桃面、丹唇、柔膝，而是深沉的意志。青春是生命的深泉在涌流.whether 60 of 16 , there is in every human being ?s heart the lure of wonders, the unfailing childlike appetite of what?s next and the joy of the game of living.in the center of your heart and my heart there?s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young.a poet said “to see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour.several days ago, i had a chance to listen to a lecture.i learnt a lot there.i?d like to share it with all of you.let?s show our right palms.we can see three lines that show how our love.career and life is.i have a short line of life.what about yours? i wondered whether we could see our future in this way.well, let?s make a fist.where is our future? where is our love, career, and life? tell me.yeah, it is in our hands.it is held in ourselves.一位詩(shī)人說(shuō)?從一粒沙看世界，從一朵花看天堂，把無(wú)限放在你的手掌，永恒在一剎那里收藏?。幾天前，我有了一個(gè)聽(tīng)講座的機(jī)會(huì)，從中我學(xué)到了很多東西。現(xiàn)在，我想把這些與大家共享。讓我們伸出右手，我們可以看到手掌中的展示我們的愛(ài)，事業(yè)和生活的三條線。我在生活方面這條線很短，那你們的呢?我想知道我們是否可以用這種辦法去看我們的未來(lái)。好的，讓我們一起握拳。我們的未來(lái)在哪兒?我們的愛(ài)、事業(yè)和生活在哪兒?告訴我!是的，它們就在我們的手中。它們被我們自己掌握著。

if youre middle-aged and your memorys not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do.the findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life.reporting in the journal neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link.but its also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain.measurement of weight in relation to height used to define overweight and obesity.a bmi of 25 or more indicates overweight, and 30 or more is obese.the study also investigated the relationships between bmi and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in france through the use of four cognitive tests.the study found a higher bmi was associated with lower cognitive test scores.results from a test involving word memory recall show people with a bmi of 20 remembered an average of nine out of 16 words, while people with a bmi of 30 remembered an average of seven out of 16 words.研究報(bào)告在《神經(jīng)學(xué)》期刊上發(fā)表，研究人員推斷，心血管疾病及糖尿病的高發(fā)現(xiàn)象可以解釋其中的原因。此外，脂肪細(xì)胞所產(chǎn)生的物質(zhì)，如瘦體激素，對(duì)大腦有直接影響。此項(xiàng)研究將調(diào)查對(duì)象的智力與體重指數(shù)進(jìn)行了對(duì)比。體重指數(shù)指的是身高和體重之間的比例，主要用來(lái)衡量一個(gè)人是否偏胖或肥胖。體重指數(shù)為25或25以上的人偏胖，達(dá)到30或30以上的人則為肥胖。

研究人員還對(duì)體重指數(shù)和認(rèn)知功能間的關(guān)系進(jìn)行了研究，他們?cè)诜▏?guó)對(duì)2223位年齡在32歲至62歲間的健康男女進(jìn)行了認(rèn)知測(cè)試。

研究發(fā)現(xiàn)，體重指數(shù)越大，認(rèn)知測(cè)試的得分越低。其中一項(xiàng)單詞記憶的測(cè)試結(jié)果表明，在16個(gè)單詞中，體重指數(shù)為20的人平均能記住9個(gè)，而體重指數(shù)為30的人平均只能記住7個(gè)。

people who do not get enough sleep are more than twice as likely to die of heart disease, according to a large british study released monday.a 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.the findings highlight a danger in busy modern lifestyles, francesco cappuccio, professor of cardiovascular medicine at the university of warwicks medical school, told the annual conference of the british sleep society in cambridge.a third of the population of the uk and over 40 percent in the us regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.previous research has highlighted the potential health risks of shift work and disrupted sleep.but the study by cappuccio and colleagues, which was supported by british government and us funding, is the first to link duration of sleep and mortality rates.the study looked at sleep patterns of participants aged 35-55 at two points in their livesand then tracked their mortality rates until 2004.the results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.in terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(agencies)本周一公布的一項(xiàng)大規(guī)模英國(guó)調(diào)查表明，睡眠不足的人死于心臟病的幾率是睡眠充足者的兩倍多。

目前其中的原因尚不清楚，但研究人員稱(chēng)，睡眠不足會(huì)導(dǎo)致血壓升高，從而增大患心臟病和中風(fēng)的風(fēng)險(xiǎn)。

一項(xiàng)針對(duì)1萬(wàn)名政府職員、長(zhǎng)達(dá)17年的跟蹤調(diào)查表明，每晚睡眠時(shí)間從七個(gè)小時(shí)減少到五個(gè)小時(shí)或更少的人因各種原因而死亡的幾率是睡眠正常者的1.7倍，而且死于心血管疾病的風(fēng)險(xiǎn)也增加了1倍多。

沃里克大學(xué)醫(yī)學(xué)院的心血管藥物學(xué)教授弗朗西斯哥?卡普西奧在英國(guó)睡眠學(xué)會(huì)在劍橋召開(kāi)的一年一度的研討會(huì)上說(shuō)，這一研究成果揭示了忙碌的現(xiàn)代生活中潛在的危險(xiǎn)。

他在接受記者采訪時(shí)說(shuō)：“三分之一的英國(guó)人以及超過(guò)40%的美國(guó)人每晚的睡眠時(shí)間常常達(dá)不到五個(gè)小時(shí)，所以這個(gè)問(wèn)題不可小視。”

此前有調(diào)查發(fā)現(xiàn)輪班及睡眠中斷會(huì)對(duì)健康產(chǎn)生潛在威脅。但卡普西奧及其同事的這項(xiàng)調(diào)查則首次揭示了睡眠時(shí)間長(zhǎng)短與死亡率之間的關(guān)系。該調(diào)查由英國(guó)政府和美國(guó)基金提供資助。

該調(diào)查對(duì)年齡在35歲至55歲之間的人在1985年至1988年以及1992年至1993年兩個(gè)階段的睡眠模式進(jìn)行了探究，并對(duì)這一人群截至2004年的死亡率進(jìn)行了追蹤。

調(diào)查還考慮到了調(diào)查對(duì)象的初始年齡、性別、是否吸煙喝酒、體重指數(shù)、血壓及膽固醇指標(biāo)等其它可能的風(fēng)險(xiǎn)因素。

卡普西奧說(shuō)，睡眠時(shí)間過(guò)長(zhǎng)也可能導(dǎo)致如抑郁癥及癌因性疲乏等其它健康問(wèn)題。他說(shuō)：“就預(yù)防而言，我們的研究結(jié)果表明，每晚睡眠時(shí)間持續(xù)保持在七小時(shí)左右最益于身體健康。

（一）Good afternoon，ladies and gentlemen！

I’m very honored to stand here and give you a short speech!To begin with ,I want to ask a question.Does everybody dream a good dream last night? Actually ,today I want to talk about dream with you.Of course, What I want to talk is not a dream you have last night,but a dream—— about life.Everyone has dreams about life, different dreams at different life stage,and we need dreams to support us.Dreams are like the stars we never reach in the sky,but like most mariners（水手）,we can chart our course by them.With the dream,we have a direction,with a direction, we were no longer confused.With the dream, there is hope,With hope, we have the strength to fight.But I know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead.Young!Fortunately, I am young now.Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way.I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses.If no people believe you, you can make it to prove that you are right.If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.“My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains.” At some time in the past I also had am bitious words and I had some achievements.Each achievement results from my hard work.I always believe that “If you want to have more achievements than others, you must work harder.”

In some extent, the dream is the hope.If you can insist on doing something, the victory will come.Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly.Hold fast to dreams, for when dreams go, life is a barren field frozen with snow.So my dear friends,think of your old and maybe dead dreams.Whatever it is, pick it up and make it alive from today.Let's---move---out!

Thank you for your listening!

（二）Good afternoon，ladies and gentlemen！

I’m very honored to stand here and give you a short speech!my topic is Opportunities and Challenges.First, I would like to know, what does your destiny offer you? Happiness, wisdom, a strong body or something else.If I had asked this question to president Nixon, he would probably had said,”O(jiān)ur destiny offers not the cup of despair, but the chalice of opportunity.”

Needless to say, one of the biggest opportunities given to China is the 2015 Olympic Games.Till now, we have used two sevenths of the preparation time.How much changes have you seen? New roads, new subway lines, public-exercising equipments with beautiful colors,()large blocks of grass fields, and also lots of modern gyms which are under construction.Other than those, there are even more good effects brought to us by the Olympic Games that cannot be seen directly.For example, more and more people will get to know China.I’m sure the mysterious Chinese culture will attract them strongly.And the games will also do good to the economy and environment, for it is gaining the attention of foreign investors and the awareness of environmental protection is being strengthened.What is more, Olympic Games give a unique opportunity to inspire and educate a new generation of Chinese youth with the Olympic values and the Olympic spirit.Now that we have seen so many advances, could you even imagine us losing the holding rights?

I’ve already said a lot about the Olympics and China.But I think everyone should use some time to think of this question, ”Does the Olympic Games have any special meaning to you?”

For us, I mean the Chinese youth, 2015 Olympic Games is a tremendous gift.Because what we are waiting for is to do something significant as repaying the love given to us.The society is just like a ship, and in our dreams the captain is waving his hand and saying ”Hey!Come here and take the helm!”How charming his voice is, but we have never heard of it in our true life.This morning, however, when we wake up, we will see the Olympic Games waving its hand.After chewing, most of us will have at least one plan about what to do for the Olympic Games.And mine is to be a “comforter”----that is someone who will give comfort to others.At the end of my speech, I hope all the preparation will go well, and everyone will show their ability to the world.Let us seize opportunities and give a big smile to challenges.大學(xué)三分鐘英語(yǔ)演講稿

（三）Good afternoon everybody!It's my honor to speak here and I am very glad to share my topic with all of you.Today I'd like to talk about “my dream”.I do not just have one dream, in fact, I have three.They are: a healthy life, a happy family and to travel my great country.I have always admired the long healthy life my grandparents have.They are older than 80 years of age and they are still alive and kicking!How do they do that!? My grandparents plant vegetables and grow rice themselves;even in their old age they still make food for themselves!I guess that is why they can remain healthy.More importantly they remain humble and never ask for too much from life.Perhaps that makes them common, but they live a happy life.My grandmother once told me this:” I do not want to live long, only long enough for some grand children to be running around in my house”.I want to live a long, healthy and happy life just as they have.Since my graduation from primary school, until now, every time on my birthday I make the same wish.I wish my parents will not fight anymore.I am not complaining that they gave me a bad childhood, they just fight so much!I am unhappy but that does not mean they do not love me.They do!They love me with all their heart.I love my parents also;I want them to live a happy life as well.I want to travel this great country of ours.I want to see the beauty of our country.I want to see the miracles that made this country great!I want to go from the east to west, from the north all the way down to the south!I have a dream, that one day I can travel and see my country with my family and friends!If that is not possible, seeing my country on my own is good enough also.If I can fulfill all three of my dreams in life, then God can take me away.I would be happy, and l would have lived a full and prosperous life.Thank you everyone for listening to my dreams.I thank you!

i am very glad to stand here to give thier a short speech.today my topic is that the youth are the future of motherland 很高興站在這里做這篇短小的演講，我演講的主題是青年是祖國(guó)的未來(lái)。

在準(zhǔn)備英語(yǔ)演講比賽的時(shí)候，我本想簡(jiǎn)單地從網(wǎng)上搜索一些文章作為我演講的內(nèi)容。我看過(guò)很多文章，有著名主持人的、北大教授的、大學(xué)生的，也有初中生的。但是看完之后，我放棄了當(dāng)初的想法，我甚至為當(dāng)初的想法感到有一些羞愧。因?yàn)榻裉煳艺驹谶@里向大家演講的主題，是一個(gè)莊重而嚴(yán)肅的主題；是一個(gè)充滿榮耀與自豪的主題；是每一個(gè)中華兒女共同期盼的主題。每個(gè)人都有屬于他們自己的中國(guó)夢(mèng)，而我，當(dāng)然也有一直縈繞在心懷只屬于我的中國(guó)夢(mèng)。

so what?s my chinese dream ? finally i will announce.we had learned a lot of knowledge and understood a lot of truth in the book.we had a basic concept to our country at that time.we know that our country is full of sunshine , and we are the future of our country, and our dreams are to be the hope of our motherland.我的中國(guó)夢(mèng)是什么樣的？先賣(mài)個(gè)關(guān)子。

記得剛剛上學(xué)那會(huì)兒，我們天真無(wú)邪。在課本里，我們學(xué)到了很多很多知識(shí)，也明白了很多很多道理，我們對(duì)祖國(guó)也有了一個(gè)最基本的概念。我們知道我們的祖國(guó)到處充滿陽(yáng)光，正在慢慢發(fā)展，而我們，就是祖國(guó)未來(lái)的花朵，未來(lái)的希望。我們夢(mèng)想將來(lái)能夠成為祖國(guó)的希望。

這，是我們最初的中國(guó)夢(mèng)。最真誠(chéng)的我們，最真誠(chéng)的夢(mèng)。

但是，不知道什么時(shí)候開(kāi)始，我們長(zhǎng)大了，生活似乎一下子變得和以前不太一樣了，與此同時(shí)，雖然我們很不想承認(rèn)但是卻又不得不承認(rèn)的是，我們的思想，我們的為人處世觀，我們對(duì)我們祖國(guó)的看法，也潛移默化中慢慢開(kāi)始了轉(zhuǎn)變。我們的社會(huì)變得到處充滿欺騙、冷漠、勾心斗角、壓力、腐敗、險(xiǎn)惡，我們變得暴躁，不冷靜，憤世嫉俗。我們的國(guó)家，似乎也開(kāi)始變得千瘡百孔。而好多我們親愛(ài)的祖國(guó)委以重任培養(yǎng)的青年學(xué)生們變得輕浮、急躁，更別提什么夢(mèng)想，什么中國(guó)夢(mèng)了？

are we sick, or is our dear motherland sick? 我很驚訝，當(dāng)大街上有老人摔倒，我們不敢再去扶起；我很難過(guò)，當(dāng)有人做了好事被報(bào)道，更多的人說(shuō)他做作；我很傷心，當(dāng)我看到我們眾多的青年人變得冷漠、市儈、欺詐以及缺乏理想。

到底是我們病了，還是我們親愛(ài)的祖國(guó)病了？

i dont want to talk about the construction of our country politics, and also speak impassioned speech on the diaoyu island event.i just want to appeal young people,showing the side of youth,good and confidence.we must learn to organize our own thoughts, correct our own concept, and change our direction to the right side in future life.china dream actually lies in our young generation, especially of the intellectuals.我的中國(guó)夢(mèng)，不想大談?wù)危膊幌雽?duì)釣魚(yú)島事件發(fā)表慷慨激昂的演講。我只想呼吁，呼吁我們年輕人，呼吁我們祖國(guó)的希望能夠?qū)⑽覀兊那啻阂幻妫瑢⑽覀兊纳屏家幻妫瑢⑽覀兊淖孕乓幻婧煤谜宫F(xiàn)出來(lái)。我們要學(xué)會(huì)整理自己的思想，端正自己看問(wèn)題的觀念，擺正自己的人生方向。我們的中國(guó)夢(mèng)實(shí)際上正掌握在我們自己手上，掌握在我們年青一代，尤其是知識(shí)分子手上。

也許，一個(gè)人，是渺小的；但是當(dāng)他和祖國(guó)聯(lián)系起來(lái)時(shí)，就是偉大的。也許，一個(gè)夢(mèng)想，是渺小的，但是當(dāng)它成為祖國(guó)的夢(mèng)想時(shí)，就是不可估量的。也許，我無(wú)法用自己一個(gè)人的力量撬起整個(gè)中國(guó)，但是我們千千萬(wàn)萬(wàn)年輕人一起為祖國(guó)的夢(mèng)想去奮斗時(shí)，我們的祖國(guó)就足以令世界顫抖、動(dòng)容。

i dream to construct our beauty china with millions of young people who have the same dream.we do it without exaggeration but only with persistence.我夢(mèng)想和萬(wàn)千具有相同夢(mèng)想的年輕人去建設(shè)我們的美麗中國(guó)，沒(méi)有虛浮，只有執(zhí)著，只有奮斗，只有勇于擔(dān)當(dāng)。這就是我的中國(guó)夢(mèng)！that is my speech,thanks everyone.我的演講就到這里，謝謝大家。we are the world ,we are the future 世界是我們的，未來(lái)是我們的

someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”.i don?t know who wrote these words, but i?ve always liked them as a reminder that the future can be anything we want it to be.we are all in the position of the farmers.if we plant a good seed ,we reap a good harvest.if we plant nothing at all, we harvest nothing at all.一些人說(shuō)?我們正在讀一本無(wú)窮的書(shū)中的第一章的第一節(jié)。?我不知道誰(shuí)寫(xiě)了這些話，但是我一直很喜歡它，因?yàn)樗嵝蚜宋遥覀兡軌騽?chuàng)造我們想要的未來(lái)。we are young.“how to spend the youth?” it is a meaningful question.to answer it, first i have to ask “what do you understand by the word youth?” youth is not a time of life, it?s a state of mind.it?s not a matter of rosy cheeks, red lips or supple knees.it?s the matter of the will.it?s the freshness of the deep spring of life.我們都是農(nóng)夫。如果我們播下好的種子，我們將會(huì)豐收。如果我們的種子很差，有很多草籽，收割的將是無(wú)用的莊稼。如果我們什么也不播種，什么收獲也沒(méi)有。youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease.this often exists in a man of 60 more than a boy of 20.nobody grows old merely by a number of years.we grow old by deserting our ideals.years wrinkle the skin , but to give up enthusiasm wrinkles the soul.worry , fear , self –distrust bows the heart and turns the spirit back to dust.我們是年輕的。?怎樣度過(guò)青春??這是個(gè)有意義的問(wèn)題。為了去回答它，我首先要問(wèn)?從‘青春’這個(gè)詞中你能理解到什么?? 青春不是人生的一個(gè)時(shí)期，而是精神的一種狀態(tài)。青春不是桃面、丹唇、柔膝，而是深沉的意志。青春是生命的深泉在涌流.whether 60 of 16 , there is in every human being ?s heart the lure of wonders, the unfailing childlike appetite of what?s next and the joy of the game of living.in the center of your heart and my heart there?s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young.a poet said “to see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour.several days ago, i had a chance to listen to a lecture.i learnt a lot there.i?d like to share it with all of you.let?s show our right palms.we can see three lines that show how our love.career and life is.i have a short line of life.what about yours? i wondered whether we could see our future in this way.well, let?s make a fist.where is our future? where is our love, career, and life? tell me.yeah, it is in our hands.it is held in ourselves.一位詩(shī)人說(shuō)?從一粒沙看世界，從一朵花看天堂，把無(wú)限放在你的手掌，永恒在一剎那里收藏?。幾天前，我有了一個(gè)聽(tīng)講座的機(jī)會(huì)，從中我學(xué)到了很多東西。現(xiàn)在，我想把這些與大家共享。讓我們伸出右手，我們可以看到手掌中的展示我們的愛(ài)，事業(yè)和生活的三條線。我在生活方面這條線很短，那你們的呢?我想知道我們是否可以用這種辦法去看我們的未來(lái)。好的，讓我們一起握拳。我們的未來(lái)在哪兒?我們的愛(ài)、事業(yè)和生活在哪兒?告訴我!是的，它們就在我們的手中。它們被我們自己掌握著。

we all want the future to be better than the past.but the future can go better itself.don?t cry because it is over, smile because it happened.from the past, we?ve learnt that the life is tough, but we are tougher.we?ve learnt that we can?t choose how we feel, but we can choose what about it.failure doesn?t mean you don?t have it, it does mean you should do it in a different way.failure doesn?t mean you should give up, it does mean you must try harder.我們所有人都希望未來(lái)能比過(guò)去更美好，但是未來(lái)能自己變得更好。不要因?yàn)榻Y(jié)束而哭泣，微笑吧，為你的曾經(jīng)擁有。從過(guò)去來(lái)看，生活是艱苦的，但我們是更堅(jiān)強(qiáng)。我們知道我們不能選擇感覺(jué)，但是我們能選擇和它相關(guān)的東西。失敗并不意味著你不擁有成功，它只意味著你應(yīng)該用另一種方式去做這件事。失敗并不意味著你應(yīng)該放棄，只意味著你應(yīng)該更加努力。

as what i said at the beginning, “we are reading the first verse of the first chapter of a book, whose pages are infinite”.the past has gone.nothing we do will change it.but the future is in front of us.believe that what we give to the world, the world will give to us.and from today on, let?s be the owners of ourselves, and speak out “we are the world, we are the future.”

正如我在前面所說(shuō)的?我們正在讀一本無(wú)窮的書(shū)中的第一章的第一節(jié)。?過(guò)去的已經(jīng)過(guò)去，無(wú)論我們無(wú)力改變，但是未來(lái)卻在我們前方。相信?我們給了世界什么，世界也將給我們?。并且從今天起，讓我們一起做我們自己的主人，一起大聲說(shuō)出?世界是我們的，未來(lái)是我們的。? friendship 友誼

every one of us, rich or poor, should at least have one or two good friends.my friends will listen to me when i want to speak, will wipe my eyes when i cry, will take care of me when i am sick, and my friends will go together with me side by side through this journey of life.我們每個(gè)人,不論富裕還是貧窮,至少應(yīng)該有一個(gè)或兩個(gè)好朋友。我的朋友會(huì)聽(tīng)我說(shuō),如果我想說(shuō)話,要擦去我的眼睛當(dāng)我哭泣,會(huì)照顧我在我生病時(shí),我的朋友將與我一起肩并肩在這人生旅程。

friendship is a kind of treasure in our lives.it is actually like a bottle of wine, the longer it is kept, the sweeter it will be.it is also like a cup of tea.when we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink.友誼是一種財(cái)寶在我們的生活。它實(shí)際上是像一瓶酒,越久保留,這將是更香甜。它就像一杯茶。當(dāng)我們口渴時(shí),這將是對(duì)我們最好的選擇,但當(dāng)我們有足夠的時(shí)間去玩得很開(kāi)心的,它也是最芬芳的飲料。

我們所有的人都要花點(diǎn)時(shí)間來(lái)個(gè)人的生活。我們必須找到機(jī)會(huì)來(lái)表達(dá)我們的感情和愛(ài)。當(dāng)住在我們的朋友,我們可以放松自己完全。我們可以做任何我們想要的,我們能一起大聲笑,一起交談,甚至哭泣下。我應(yīng)該說(shuō),是我們最好的朋友一起是最精彩的時(shí)刻,我們的生活。as we know, we would feel lonely if we didnt even have a friend.but it doesnt mean we could depend on our friends all the time.there is a famous motto saying that “a friend is like a quilt with cotton wadding, but the real thing that keeps you warm is your own temperature.” it is really true.we have to work hard together with our friends, encourage each other and help each other.when we receive love and friendship, we should repay as much as we can.正如我們所知道的,我們會(huì)感到寂寞,如果我們還沒(méi)有一個(gè)朋友。但這并不意味著我們可以依靠我們的朋友。有個(gè)著名的格言說(shuō):?一個(gè)朋友就像一個(gè)棉花棉絲被子,但真正的東西,是使你暖和是你自己的溫度。?這是真的。我們必須努力同我們的朋友,互相激勵(lì),互相幫助。當(dāng)我們能收到更多的愛(ài)與友誼,我們應(yīng)該償還高達(dá)就可以了。

finally, lets pray together now that one day, all of us could find the person we want to find, and could enjoy a real beautiful friendship in our lives.lets pray the flower of friendship be-tween our friends and us would always bloom brightly in our hearts 最后,讓我們一起祈禱了,有一天,我們都能找到我們想找的人,就可以享受一段美好友誼的真正左右我們的生活了。讓我們一起祈禱友誼之花卻成為我們的朋友,我們將永遠(yuǎn)綻放鮮艷的在我們的心中

篇四：大學(xué)英語(yǔ)演講比賽3分鐘演講 my china dream for 170 years, thousands of our forbears have given their energy, their faith, their devotion and even their lives for the realization of this dream.they bring their endeavor to the great rise and rejuvenation of our country, they melted their dreams deeply to the dream of china, and light our country, we can feel the glow from its fire, and we believe that this fire can truly light the world!and now, it’s our turn to take on this endeavor, for the pursuit of our own dream, also for the realization of the dream of our nation!finally, i want to finish my speech with the words from president kennedy’s first inaugural address: with a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking his blessing and his help, but knowing that here on earth, gods work must truly be our own!篇五：大學(xué)三分鐘英語(yǔ)演講稿 soy food good for women women who ate soy regularly as children have a lower risk of breast cancer, american researchers report.and men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the american association for cancer research.many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or cox-2 enzyme.cox-2 affects inflammation, which may play a role in tumour growth.據(jù)美國(guó)研究人員報(bào)告，兒童時(shí)期經(jīng)常吃豆類(lèi)食品的女性患乳腺癌的風(fēng)險(xiǎn)較小。另一組研究人員則向美國(guó)癌癥研究協(xié)會(huì)提出，一周吃幾次魚(yú)的男性患結(jié)腸癌的幾率較小。

這兩項(xiàng)研究進(jìn)一步證明了飲食對(duì)于防癌的作用。癌癥防治專(zhuān)家認(rèn)為，在所有種類(lèi)的癌癥中，多達(dá)三分之二都是由吸煙、節(jié)食及缺乏鍛煉等不健康的生活方式造成的。

美國(guó)全國(guó)癌癥研究所和夏威夷大學(xué)的研究人員發(fā)現(xiàn)，在5歲至11歲時(shí)經(jīng)常吃豆腐、味噌等豆類(lèi)食品的女性患乳腺癌的幾率要低58%。至于豆類(lèi)食品為什么可以防癌還不清楚，不過(guò)大豆中所含的名叫異黃酮的化合物具有雌性激素的作用。

另一項(xiàng)研究表明，一周吃魚(yú)至少五次的男性患結(jié)腸癌的風(fēng)險(xiǎn)要比那些一周都吃不到一次魚(yú)的男性低40%。

很多魚(yú)類(lèi)中所富含的omega-3脂肪酸能夠抑制環(huán)氧化酶2的活性。環(huán)氧化酶2會(huì)引起發(fā)炎，這可能會(huì)刺激腫瘤的生長(zhǎng)。

if youre middle-aged and your memorys not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do.the findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life.reporting in the journal neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link.but its also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain.measurement of weight in relation to height used to define overweight and obesity.a bmi of 25 or more indicates overweight, and 30 or more is obese.the study also investigated the relationships between bmi and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in france through the use of four cognitive tests.the study found a higher bmi was associated with lower cognitive test scores.results from a test involving word memory recall show people with a bmi of 20 remembered an average of nine out of 16 words, while people with a bmi of 30 remembered an average of seven out of 16 words.研究人員提醒，如果你已步入中年，發(fā)現(xiàn)自己的記憶力不如從前，那么你得小心體重了。研究表明，超重的人記憶測(cè)試的得分要比較瘦的人低。

研究發(fā)現(xiàn)，體重偏大的中年人今后患老年癡呆癥的可能性較大。

研究報(bào)告在《神經(jīng)學(xué)》期刊上發(fā)表，研究人員推斷，心血管疾病及糖尿病的高發(fā)現(xiàn)象可以解釋其中的原因。此外，脂肪細(xì)胞所產(chǎn)生的物質(zhì)，如瘦體激素，對(duì)大腦有直接影響。

此項(xiàng)研究將調(diào)查對(duì)象的智力與體重指數(shù)進(jìn)行了對(duì)比。體重指數(shù)指的是身高和體重之間的比例，主要用來(lái)衡量一個(gè)人是否偏胖或肥胖。體重指數(shù)為25或25以上的人偏胖，達(dá)到30或30以上的人則為肥胖。

研究人員還對(duì)體重指數(shù)和認(rèn)知功能間的關(guān)系進(jìn)行了研究，他們?cè)诜▏?guó)對(duì)2223位年齡在32歲至62歲間的健康男女進(jìn)行了認(rèn)知測(cè)試。

研究發(fā)現(xiàn)，體重指數(shù)越大，認(rèn)知測(cè)試的得分越低。其中一項(xiàng)單詞記憶的測(cè)試結(jié)果表明，在16個(gè)單詞中，體重指數(shù)為20的人平均能記住9個(gè)，而體重指數(shù)為30的人平均只能記住7個(gè)。

people who do not get enough sleep are more than twice as likely to die of heart disease, according to a large british study released monday.although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.a 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.the findings highlight a danger in busy modern lifestyles, francesco cappuccio, professor of cardiovascular medicine at the university of warwicks medical school, told the annual conference of the british sleep society in cambridge.a third of the population of the uk and over 40 percent in the us regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.previous research has highlighted the potential health risks of shift work and disrupted sleep.but the study by cappuccio and colleagues, which was supported by british government and us funding, is the first to link duration of sleep and mortality rates.the study looked at sleep patterns of participants aged 35-55 at two points in their livesand then tracked their mortality rates until 2004.the results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.in terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(agencies)本周一公布的一項(xiàng)大規(guī)模英國(guó)調(diào)查表明，睡眠不足的人死于心臟病的幾率是睡眠充足者的兩倍多。

目前其中的原因尚不清楚，但研究人員稱(chēng)，睡眠不足會(huì)導(dǎo)致血壓升高，從而增大患心臟病和中風(fēng)的風(fēng)險(xiǎn)。

一項(xiàng)針對(duì)1萬(wàn)名政府職員、長(zhǎng)達(dá)17年的跟蹤調(diào)查表明，每晚睡眠時(shí)間從七個(gè)小時(shí)減少到五個(gè)小時(shí)或更少的人因各種原因而死亡的幾率是睡眠正常者的1.7倍，而且死于心血管疾病的風(fēng)險(xiǎn)也增加了1倍多。

沃里克大學(xué)醫(yī)學(xué)院的心血管藥物學(xué)教授弗朗西斯哥?卡普西奧在英國(guó)睡眠學(xué)會(huì)在劍橋召開(kāi)的一年一度的研討會(huì)上說(shuō)，這一研究成果揭示了忙碌的現(xiàn)代生活中潛在的危險(xiǎn)。

他在接受記者采訪時(shí)說(shuō)：“三分之一的英國(guó)人以及超過(guò)40%的美國(guó)人每晚的睡眠時(shí)間常常達(dá)不到五個(gè)小時(shí)，所以這個(gè)問(wèn)題不可小視。”

此前有調(diào)查發(fā)現(xiàn)輪班及睡眠中斷會(huì)對(duì)健康產(chǎn)生潛在威脅。但卡普西奧及其同事的這項(xiàng)調(diào)查則首次揭示了睡眠時(shí)間長(zhǎng)短與死亡率之間的關(guān)系。該調(diào)查由英國(guó)政府和美國(guó)基金提供資助。

該調(diào)查對(duì)年齡在35歲至55歲之間的人在1985年至1988年以及1992年至1993年兩個(gè)階段的睡眠模式進(jìn)行了探究，并對(duì)這一人群截至2004年的死亡率進(jìn)行了追蹤。

調(diào)查還考慮到了調(diào)查對(duì)象的初始年齡、性別、是否吸煙喝酒、體重指數(shù)、血壓及膽固醇指標(biāo)等其它可能的風(fēng)險(xiǎn)因素。

卡普西奧說(shuō)，睡眠時(shí)間過(guò)長(zhǎng)也可能導(dǎo)致如抑郁癥及癌因性疲乏等其它健康問(wèn)題。

他說(shuō)：“就預(yù)防而言，我們的研究結(jié)果表明，每晚睡眠時(shí)間持續(xù)保持在七小時(shí)左右最益于身體健康。
