When Christopher Columbus landed on the then unnamed Costa Rica in 1502, he saw many Indians wearing gold earrings.So he thought the land must be rich in gold.He named the place Costa Rica, which means “rich coast” in Spanish.Though little gold was found, Costa Rica today is indeed rich with coffee and bananas.Coffee is the most important product in Costa Rica and most of it is exported(出口)to other countries like America and West Germany.Bananas are the country’s second most important export.Costa Ricans also grow many other crops such as fruits, corn and beans for their own use.Costa Ricans love colors and their houses are painted in bright colors.Education is very important to the Costa Ricans.Almost every village has a school and education is a must for children between seven and fourteen years of age.Boys and girls go to separate(單獨(dú)的)schools.Classes begin in March and end in November.The other three months of the year are harvest time and the children have to help their parents to pick coffee beans.51.What’s the main idea of the first paragraph?

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java.Many peopleAt first, Eijkman thought some kind of germ(細(xì)菌)caused beri-beri.He raised some chickens.He didn’t eat them, but made experiments on them.The local people were quite surprised at that.One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice(精煉米).When he fed them with unrefined rice, also known as brown rice, they recovered.Eijkman realized that he had made an important discovery — that some things in food could prevent disease.These things were named vitamins(維生素).The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins.Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat.If they don’t, they can also take vitamin pills.56.The underlined word “cure” in Paragragh 1 probably means ______.A.a medical treatmentB.a kind of vitamin C.a kind of germD.a kind of rice

57.Christian Eijkman went to the island of Java to ______.A.spend his holiday

B.find ways to grow better cropsC.do some research about the island D.help the Javanese with their illness

58.Why did Christian Eijkman raise some chickens? A.To eat them.B.To carry out his experiments.C.To give the Javanese a surprise.D.To make money by selling them.59.If a person doesn’t get enough vitamins in his diet, he’d better ______.A.eat more riceB.eat more meat C.eat some chickenD.eat vitamin pills 60.We can learn from the passage that ______.A.beri-beri was caused by chickens B.the Javanese didn’t like vitamins

D.the Javanese’s disease was caused by a kind of germ

C ★★

America is a mobile society.Friendships between Americans can be close and real, yet disappear soon if situations change.Neither side feels hurt by this.Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more.If the same two people meet again by chance, even years later, they pick up the friendship.This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending(延伸)sometimes deeply into both families.Americans are ready to receive us foreigners at their homes, share their holidays, and their home life.They will enjoy welcoming us and be pleased if we accept their hospitality(好客)easily.Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time.This is usually the opposite of the practice in our country where we may be night to meet a friend.We may take days off to act as guides to our foreign friends.The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine.They will probably expect us to get ourselves from the airport to our own hotel by bus.And they expect that we will phone them from there.Once we arrive at their homes, the welcome will be full, warm and real.We will find ourselves treated hospitably.For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters.So accept their hospitality at home!61.The writer of this passage must be ______.A.an AmericanB.a ChineseC.a professorD.a student 62.Which of the following statements is TRUE according to the passage? A.Friendships between Americans usually extend deeply into their families.B.Friendships between Americans usually last for all their lives.C.Americans always show their warmth even if they are very busy.D.Americans will continue their friendships again even after a long break.63.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.A.warmly welcomed at the airportB.offered a ride to his home

C.treated hospitably at his homeD.treated to dinner in a restaurant

64.The underlined words “generous with our time” in Paragraph 3 probably mean ______.A.strict with timeB.serious with time C.careful with timeD.willing to spend time

65.A suitable title for this passage would probably be “______”.A.Friendships between ChineseB.Friendships between Americans C.Americans’ hospitality

D.Americans’ and Chinese’s views of friendships

The other day I heard a few local musicians talking:

“I hate all the terrible pianos in this town.I hate that rubbish they play on the radio.They can’t even understand a bit of music.”“I’m never playing in that club again.Too many drunks and nobody listens to us.”But, one younger musician said, “There are a few clubs that book my band a few nights a month, and I’m trying to find other places to play.I’m also looking to book a few summer festivals this year.”I’ve heard that you are the average of the five people whom you spend the most time with, or to put it another way, you are who your friends are.you’re around people who complain about lack of work and about other musicians, or blame(責(zé)怪)others, and you play the role of victim(受害者), chances are you will start to as well.So it’s time to take a look at the people you call “friends”.This is an easy exercise: Make a list of the people who you hang out with, and simply stop spending time with the negative people on your list.Set a new standard(標(biāo)準(zhǔn))for yourself and don’t become friends with people who fall below that standard.Keep successful people around you and your own chances for success will be much better.Ask them how they do it.Ask if they will help you get the work you’re looking for, or maybe give you some advice to help you on your career path.66.Which of the following would be the best title for this passage? A.A friend in need is a friend indeed B.How to make friendship last for ever C.You are who your friends are

D.Friends are the most important in one’s success

67.The underlined sentence “they’re rubbing off on you” in Paragraph 6 means ______.A.they’ll push you ahead B.they’ll influence you

C.they’ll cover your shortcomings D.they’ll help you achieve your goal

68.The musicians’ words at the beginning are written mainly to show ______.A.the musicians’ living conditions are quite poor B.people have poor taste in music

C.people have different attitudes towards the same thing D.young people have greater chances of succeeding

69.By taking the exercise mentioned in Paragraph 7, you can ______.A.improve a lot in making more friends B.come to the right way of making friendsC.develop a better relationship with your friends D.arrange the time with your friends properly 70.The passage is mainly written for ______.A.musiciansB.managersC.negative people

This lesson is taken from the New Senior English for China, Student’s Book1, and Unit1 Friendship.It is the second period of this unit.Unit 1 mainly talks about friendship and the problems appearing in it.Today’s lesson focuses on Reading and Comprehending.In warming-up and Pre-reading, the students have learned some vocabulary and expressions about friendship.Therefore, when talk about best friend, they will be more interested and have more ideas & opinions.Reading part is a diary of Anne, which talks about Jewish girl Anne how to hide away from Nazis, how to get on with friend and how much she longed for friend.By studying this passage, not only will students train their reading skills and learn some new words and expressions, but also they will learn to appreciate the beauty of English and Anne’s positive attitude for life.2.Analyzing the Students

Although the students have the basic of listening, speaking, reading and writing, they still need many opportunities to practice what they have learned and express their ideas, feelings and experience.3.Analyzing Teaching Aims According to the requirement of the New English Curriculum Standard and combining with the students’ practical situation, the teaching aims of this unit as follow:(1).Knowledge Aims:

According to the New Curriculum Standard, the teacher should be the guide, organizer and the cooperator in teaching.During the class, the teacher should guide the students to learn by themselves rather than tell everything to them.Therefore, I mainly use the following teaching methods in this class.Task-based teaching approach, Communicative teaching, cooperative learning and discussion

III.Teaching procedures step1.Leading-in(5mins)The students will work in their groups to discuss these two questions: 1.What is important in your life? 2.What do you think a real friend is like?

②老師老了,頭發(fā)花白,臉上添了皺紋,背有些駝,但依然是那么和藹、親切。老師原本是可以走出鄉(xiāng)村,去過(guò)富足的生活的,可她丟不開(kāi)她的學(xué)生。http:/ /www.tmdps.cn ③老師很熱情,但也有些惶恐和拘束。我倆坐在竹片隔出的辦公室中,她說(shuō):“文老師,幾十年了,我還是一個(gè)民辦教師,可你已經(jīng)成了有名的中學(xué)教師,據(jù)說(shuō)還經(jīng)常發(fā)表文章,快要成為教師作家啦!”這下我才明白了老師惶恐和拘束的緣由。平時(shí)聽(tīng)?wèi)T別人叫我文老師,現(xiàn)在從我的老師的嘴里喊出來(lái),是多么的刺耳!她為什么不喊我“猛子”,像15年前一樣?

④15年前,我在這里讀小學(xué)。那時(shí),我是有名的調(diào)皮學(xué)生,小小校園中任何一出惡作劇都少不了我,諸如捉蛇扔進(jìn)女廁所、大路上挖陷坑、砍課桌凳烤火等等。王老師沒(méi)有放棄我,苦口婆心地教育我,甚至用選我當(dāng)班長(zhǎng)、中隊(duì)長(zhǎng)等等辦法來(lái)鞭策我,可我總是維持不了幾天“優(yōu)秀”,便又“舊病復(fù)發(fā)”。班上同學(xué)恨我,都不給我?guī)э垇?lái),蘇教版語(yǔ)文六年級(jí)上冊(cè)第七單元復(fù)習(xí)

老師就把自家?guī)?lái)的飯給我吃。后來(lái)有一次我犯了一個(gè)嚴(yán)重的錯(cuò)誤,將被學(xué)校開(kāi)除,是王老師為我在校長(zhǎng)面前多次求情,保住了我。這件事終于感動(dòng)了我這匹“野馬”。從此,我從自認(rèn)為“輝煌”的泥潭中跳了出來(lái),居然考上了初中。想起這些,我內(nèi)心十分不安。世人無(wú)不稱贊鋼的堅(jiān)硬.然而要知道是誰(shuí)把鋼從粗野的礦石中冶煉出來(lái)的呢? ⑤ 老師又去上課了。看著樹上掛著的打鐘的破犁,聽(tīng)著隔壁王老師生動(dòng)的講課,我說(shuō)不出心里的感覺(jué),我不想去討論“青出于藍(lán)而勝于藍(lán)”的哲理,只知道沒(méi)有藍(lán)便無(wú)從提煉青,只知道師恩永遠(yuǎn)!新課 標(biāo) 第 一 網(wǎng) ⑥灑向大地的雪花,天氣暖和的時(shí)候,它們的身影便無(wú)影無(wú)蹤,失去一切詩(shī)情畫意,可是青青的麥苗記著,鮮活的小溪記著,飛轉(zhuǎn)于藍(lán)藍(lán)天空中的小鳥記著??

二、非選擇題1.閱讀下面短文并回答:用小刀切下一小塊金屬鈉,切面呈銀白色,將鈉投入水中,它浮于水面,與水發(fā)生劇烈反應(yīng),并在水面急速游動(dòng),發(fā)出嘶嘶聲,頃刻間熔化成一個(gè)銀白色小球,小球逐漸縮小,最后完全消失。根據(jù)以上內(nèi)容,請(qǐng)歸納金屬鈉的有關(guān)物理性質(zhì):(1)(2)(3)(4)2.有A、B、C、D四種物質(zhì),A是無(wú)色無(wú)氣味的氣體,B在A中可以劇烈燃燒,產(chǎn)生明亮的藍(lán)紫色火焰,且生成有刺激性氣味的氣體C,將燃燒的木條伸入無(wú)色無(wú)味的D中,木條熄滅,向D中加澄清石灰水并振蕩,石灰水變渾濁。由此可以推斷: A是;B是;C是;D是。3.市場(chǎng)上有些食品裝在充滿氣體的塑料袋內(nèi),顯得鼓鼓的。經(jīng)詢問(wèn)得知:這樣充氣的包裝,主要是為了使食品能較長(zhǎng)時(shí)間保鮮、保質(zhì)和不易壓碎。那么,這是什么氣體呢? 大明猜想是二氧化碳,小明猜想是氮?dú)狻"偶僭O(shè)猜想正確,請(qǐng)你用實(shí)驗(yàn)方法證明。驗(yàn)證方法及操作可能看到的現(xiàn)象結(jié)論 4.下面這則短文是某科普雜志上一篇文章的一部分, 請(qǐng)認(rèn)真閱讀, 并回答問(wèn)題。臭氧在通常狀況下是淡藍(lán)色、有魚腥味的氣體。臭氧不穩(wěn)定,一旦受熱極易轉(zhuǎn)化成氧氣,并放出大量的熱。臭氧的氧化能力比氧氣強(qiáng)得多。臭氧層能吸收太陽(yáng)輻射中的大量紫外線,使地球上的生物免遭紫外線的傷害,它是一切生命的保護(hù)層。超音速飛機(jī)排出的廢氣中的一氧化碳、二氧化碳、一氧化氮等氣體,以及家用電冰箱中的制冷劑“氟里昂”等,對(duì)臭氧層有很大的破壞作用,會(huì)使臭氧層形成空洞,從而使更多的紫外線照射到地球表面,導(dǎo)致皮膚癌的發(fā)病率大大增加,如不采取措施,后果不堪設(shè)想。

(1)氧氣和臭氧是不是同種物質(zhì)?。

(2)將帶火星的木條伸人盛有臭氧的集氣瓶中,可以觀察到的現(xiàn)象是:(3)你認(rèn)為應(yīng)采取什么方法保護(hù)臭氧層?

5.甲、乙兩種氣體混合后通入澄清石灰水中,石灰水無(wú)明顯變化;將灼熱至發(fā)紅光的黑色固體丁放到混合氣體中,丁燃燒生成新的氣體丙,丁熄滅后,測(cè)知甲氣體已全部耗盡;往乙、丙混合氣中加入澄清石灰水,石灰水變渾濁。已知乙氣體約占空氣體積的4/5,則:(1)這些物質(zhì)分別是:甲乙丙(2)甲與丁反應(yīng)的文字表達(dá)式為。6.實(shí)驗(yàn)室制取氧氣時(shí),如果用排水法集氣時(shí),當(dāng)氣泡放出時(shí)就可以收集。當(dāng)停止反應(yīng)時(shí),如果先熄滅酒精燈,再把導(dǎo)管從水槽里撤出,造成的后果是。7.(4分)把某種金屬用小刀輕輕切下一小塊放入盛水的燒杯中,觀察到該金屬能與水劇烈反應(yīng),并放出熱,本身熔化成銀白色的小圓球,浮在水面上,根據(jù)以上敘述,推斷該金屬的物理性質(zhì)有:①硬度________;②熔點(diǎn)________;③密度________;④顏色________。8.(5分)在①潔凈的空氣;②液態(tài)氧;③四氧化三鐵;④高錳酸鉀;⑤二氧化碳;⑥自來(lái)水中

(1)屬混合物的是(填序號(hào),下同);(2)屬于純凈物的是(3)屬于氧化物的是(4)鐵絲在氧氣中燃燒是一種 9.(15分)暗紫色固體A在加熱的條件下反應(yīng)生成B和C以及D,常溫下過(guò)氧化氫溶液遇到C時(shí)分解放出D,其中C在反應(yīng)前后的質(zhì)量和化學(xué)性質(zhì)都沒(méi)有改變,若將細(xì)鐵絲放在D中點(diǎn)燃能劇烈燃燒,火星四射,生成黑色固體E。(1)寫出各物質(zhì)的名稱: A; B;C;D;E。(2)寫出有關(guān)化學(xué)反應(yīng)方程式,并指出反應(yīng)所屬的類型(化合反應(yīng)、分解反應(yīng)): ①(); ②(); ③()。(3)C是過(guò)氧化氫反應(yīng)中的。(填“催化劑”或“氧化劑”)

四、在“ 氧氣的制取和性質(zhì)”實(shí)驗(yàn)中,某同學(xué)取一段紗窗網(wǎng)上還能任意彎曲的細(xì)鐵絲,在新制較純凈的氧氣中做“鐵絲燃燒”的實(shí)驗(yàn)。結(jié)果沒(méi)有觀察到“火星四射”的現(xiàn)象,請(qǐng)分析此實(shí)驗(yàn)失敗的原因:
