Edward Wilson is America's, if not the world's, leading naturalist.In The Future of Life, he takes us on a tour of the world's natural resources.How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多樣性)of our earth.Wilson begins with an open letter to the pioneer in environment protection, Henry David

Thoreau.He compares today's Walden Pond with that of Thoreau's day.Wilson will use such

comparisons for the rest of the book.The problem is clear: man has done great damage to his home over the years.Can the Earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?

Biodiversity, Wilson argues, is the key to settling many problems the Earth faces today.Even our agricultural crops can gain advantages from it.A mere hundred species(物種)are the basis of our food supply, of which but twenty carry the load.Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.At the end of the book, Wilson discusses the importance of human values in considering the environment.If you are to continue to live on the Earth, you may as well read and act on the ideas in this book.16．What is the purpose of writing the book?

A．To call people on to protect the environment.B．To explore the nature.C．To make good use of the natural resources.D．To call on people to explore, make good use of and protect the Earth.17．We learn from the text that Wilson cares most about ________．

A．the environment for plants

B．the biodiversity of our earth

C．the waste of natural resources

D．the importance of human values

18．How many species are most important to our present food supply?

A．Twenty.B．Eighty.C．One hundred.D．Ten thousand.19．Wilson suggests that one way to keep biodiversity is to ________．

A．learn how to farm scientifically

B．build homes for some dying species

C．make it clear what to eat

D．use more species

20．We can infer that the text is ________．

A．a(chǎn) description of natural resources

B．a(chǎn) research report

C．a(chǎn) book review

D．a(chǎn)n introduction to a scientist

B

“Beating is a sign of affection, cursing(罵)is a sign of love.”

Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been—but experts say they still ring true.Today, it seems, Chinese parents are more likely to send their children to pre-college military academies in the United States in the hope that some tough love will pave the way to success.“Good education doesn't mean letting your child enjoy privileges, especially our boys，” said Song Wenming, an entrepreneur(企業(yè)家)in Jinhua, East China's Zhejiang Province.“They should be raised in tough conditions to know what to fight for in the future.”

In August, Song sent his 17-year-old son to Valley Forge Military Academy(VFMA)in Statistics shows that an increasing number of Chinese students have been registering with such academies.A few years ago, there were no Chinese students at Valley Forge.Today, there are 28.“All of the Chinese students at Valley Forge came from wealthy families, some of them were spoiled，” said Jennifer Myers, director of marketing and communications at the school.Song's only son, Song Siyu, had a rocky start during his first six weeks at the school.The teenager said he went to the school voluntarily but did not expect it to be as difficult.Now, three months later，he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision.He can even take criticism, no matter how unreasonable.“The training is hard but I know it is good for self-development of individuals，” said Song Siyu.“The endless training and scolding are just ways to build up our character, they are not personal.”

But his enthusiasm is not universal.Ten of the 13 Chinese students who joined the academy this year have transferred to other schools.But for those who stick with it, there is a reward for all the hard work.21．From the second paragraph, we can know the old Chinese saying ________．

A．is out of date in modern times

B．is disagreed by rich parents

C．is still worth trusting

D．is deeply believed by better educated parents

22．The underlined sentence means that ________.A．Song sent his only son to military school, so he feels lonely

B．Song is the only one who sends his child to military school

C．there are other people sending their children to military school besides Song

D．the fee of the military school is so high that only Song can afford it

23．Song Siyu got some achievements in the military school EXCEPT ________.A．taking a bath in a short time

B．having his meal with his eyes closed

C．taking unreasonable criticism

D．improving his character

24．How many Chinese students are there at Valley Forge before this year?

A．10.B．13.C．15.D．25.25．Which of the following can be inferred from the passage?

A．It's likely that more and more Chinese students will attend VFMA.B．Most Chinese parents approve of educating their children by beating and cursing nowadays.C．Song Siyu had no difficulty in adjusting to the life at VFMA.D．Most Chinese students support the way of education at VFMA.課時(shí)作業(yè)(四十)

Unit 2 Cloning Ⅰ.閱讀理解

A(2017·濰坊4月模擬)Every evening Sylvie left her grandmother's house at 530 to bring their cow home.The old animal spent her days out in the open country eating sweet grass.When the cow heard Sylvie's voice calling her, she would hide among the bushes, unwilling to go home.This evening it had taken Sylvie longer than usual to find her cow.The child hurried the cow through the dark forest, following a narrow path that led to her grandmother's home.“Hello, little girl，” a young man called out cheerfully.“I've been hunting for birds, but I've lost my way.” The young man explained he was a scientist, who searched for birds.“Do you put them in a cage？” Sylvie asked.“No，” he answered, “I shoot them and deal with them with special chemicals to preserve them.”

“I saw a white heron(蒼鷺)not far from here two days ago.It's a very rare bird.Have you seen it, too？” he asked Sylvie.Sylvie's heart began to beat fast.She knew that strange white bird!The young man was staring at Sylvie.“I would give $10 to the person who showed me where the white heron is.”

Sylvie had a plan that she would get the $ 10 for her grandmother and make the young man happy.Her plan was to climb to the top of a tall pine tree to see where the white heron had hidden its nest.The pine tree seemed to grow taller, the higher that Sylvie climbed.Suddenly a bird with broad white wings flew past Sylvie and landed on a pine branch below her.The white heron sat on its nest in a nearby tree.Sylvie gave a long sigh.She knew the wild bird's secret now.Slowly she began her dangerous trip down the ancient pine tree.About an hour later Sylvie returned.Both her grandmother and the young man stood up as she came into the kitchen.The splendid moment to speak about her secret had come.But Sylvie was silent.She could not tell the heron's secret and give its life away.【解題導(dǎo)語】 本文是一篇記敘文，講述了小女孩Sylvie最終因?yàn)樗纳屏级鴽]有把白蒼鷺的棲息地告訴年輕的科學(xué)家的故事。

1．Where would Sylvie usually meet the cow every evening? A.In the open country.B.Among the forest.C.On a narrow path.D.In the bushes.答案與解析：D 細(xì)節(jié)理解題。根據(jù)關(guān)鍵句可知，Sylvie是在灌木叢中遇到這頭奶牛。故D項(xiàng)符合題意。

【關(guān)鍵句】When the cow heard Sylvie's voice calling her, she would hide among the bushes, unwilling to go home.(第一段最后一句)譯文：當(dāng)這頭奶牛聽見Sylvie叫她的聲音時(shí)，她就會(huì)藏在灌木叢中，不愿意回家。2．What was the young scientist's job according to his introduction? A.Collecting birds.B.Raising birds.C.Observing birds.D.Protecting birds.答案與解析：A 推理判斷題。根據(jù)關(guān)鍵句可推知，這個(gè)年輕的科學(xué)家的工作可能是收集各種鳥類標(biāo)本。故A項(xiàng)符合題意。

【關(guān)鍵句】．..I shoot them and deal with them with special chemicals to preserve them.(第三段最后一句)譯文：??我射殺它們，并用特殊的化學(xué)藥劑來處理它們，目的是保存它們。3．What had Sylvie planned to do about the white bird? A.Make good friends with it.B.Prevent it from being caught.C.Find its nest but keep it secret.D.Find it for money and the man.答案與解析：D 細(xì)節(jié)理解題。根據(jù)關(guān)鍵句可知，因?yàn)殄X和這個(gè)年輕人，Sylvie想找到白蒼鷺。故D項(xiàng)符合題意。

【關(guān)鍵句】Sylvie had a plan that she would get the $10 for her grandmother and make the young man happy.(第五段第一句)譯文：Sylvie有了一個(gè)計(jì)劃，她可以為她的祖母掙10美元并且還能使這個(gè)年輕人高興。4．What saved the white bird's life at last? A.Grandmother's sympathy.B.The white bird's beauty.C.Sylvie's kindness.D.The young man's generosity.答案與解析：C 推理判斷題。根據(jù)文章最后一段的內(nèi)容可知，當(dāng)Sylvie找到白蒼鷺的巢的位置，回到家之后，她決定不把這個(gè)秘密告訴這個(gè)年輕人，因?yàn)樗幌氚咨n鷺丟掉性命。由此可推知，Sylvie是一個(gè)善良的小女孩。故C項(xiàng)符合題意。

【長難句分析】“I would give $10 to the person who showed me where the white heron is.”(第四段最后一句)分析：本句是一個(gè)復(fù)合句。who引導(dǎo)定語從句，修飾先行詞the person，在從句中作主語；where引導(dǎo)賓語從句，作動(dòng)詞showed的賓語。

譯文：“誰帶我去找白蒼鷺，我就給誰10美元。”

B(2017·福建省質(zhì)量檢查)When students read articles about scientific discovery, they learn what worked.Scientists present the methods that got the best result.They often show only the results that are significant and important.What they won't show are the mistakes or failures that came first.Yet sometimes those mistakes pointed the way to success.It can take a long time and many experiments to achieve scientific success.Robbin, 16, and Annabelle, 15, learned that while working this summer in a biochemistry lab at Stony Brook University in New York.What's more, they learned that failure is not necessarily something to fear.“I like the idea of scientific research，” says Robbin.It's the basis for “every lesson you learn in school and understanding everything you see in life”.This summer, Robbin has been working with Lauren, a chemistry student, who is making new drugs to fight harmful bacteria.At first, the tests made Robbin anxious.She worried that she might be making costly mistakes.But Lauren reassured her that finding out what doesn't work is“just part of the learning process”.With time, the teen got comfortable with the idea that every experiment wouldn't succeed.Annabelle also learned a lot about failure and success.She worked with graduate student Agnieszka Gil.“Sometimes I try something and it takes a while for the experiment to run.” This means that finding out whether Annabelle did something wrong can be a stressful waiting game, because “if you did something wrong you need to do it again”.But she's now learning to be patient and not to expect instant success.In science, figuring out why something failed is what may just put them on the road to success.【解題導(dǎo)語】 在閱讀科學(xué)發(fā)現(xiàn)的文章時(shí)，人們往往對(duì)科學(xué)成就過度關(guān)心，其實(shí)科學(xué)成就往往是建立在無數(shù)次失敗的基礎(chǔ)之上的。Robbin和Annabelle在實(shí)驗(yàn)室里體會(huì)到了坦然接受實(shí)驗(yàn)失敗的價(jià)值。

5．What impresses students most in articles about scientific discovery? A.Scientists' achievements.B.The reasons for success.C.The cause of mistakes.D.Stressful process of research.答案與解析：A 考查細(xì)節(jié)理解。根據(jù)第一段的第一句“When students read articles about scientific discovery, they learn what worked”以及第二段的第一句“It can take a long time and many experiments to achieve scientific success”可知，學(xué)生在閱讀科學(xué)發(fā)現(xiàn)的文章時(shí)，對(duì)科學(xué)成就的印象最為深刻，故A項(xiàng)正確。

6．What can we learn from the passage? A.Robbin is a graduate student.B.Lauren managed to make new drugs.C.Annabelle learns the value of patience.D.Agnieszka expected instant success.答案與解析：C 考查推理判斷。根據(jù)倒數(shù)第二段的最后一句“But she's now learning to be patient and not to expect instant success”可知，Annabelle學(xué)會(huì)了耐心，不期望立即成功；據(jù)此可以判斷，Annabelle知道了耐心的價(jià)值，故C項(xiàng)正確。

7．What did Robbin and Annabelle have in common in their experiments? A．They did their experiments independently.B．They realized not all experiments would succeed.C．They assisted graduate students to make new drugs.D．They made severe mistakes in the experiments.答案與解析：B 考查細(xì)節(jié)理解。根據(jù)第三段的最后一句“With time, the teen got comfortable with the idea that every experiment wouldn't succeed”可知，Robbin坦然接受了并不是每次實(shí)驗(yàn)都會(huì)成功的事實(shí)；根據(jù)第四段的最后一句“But she's now learning to be patient and not to expect instant success”可知，Annabelle學(xué)會(huì)了耐心，不期望立即成功；據(jù)此可知，Robbin和Annabelle的共同點(diǎn)是她們都意識(shí)到了不是每次實(shí)驗(yàn)都會(huì)成功，故B項(xiàng)正確。

8．What does the writer intend to tell us? A.The cause of making errors in science.B.The significance of scientific discovery.C.The importance of doing experiments.D.The correct attitudes towards failures.答案與解析：D 考查目的意圖。通讀全文可知，本文的主題句是文章最后一句“In science, figuring out why something failed is what may just put them on the road to success”；由此可知，探索科學(xué)世界，失敗是成功之母；據(jù)此可以判斷，本文旨在告訴人們對(duì)待失敗的正確態(tài)度，故D項(xiàng)正確。

(2017·河北石家莊考試)

How to Avoid an Internet Addiction

While it may seem like everyone surfs the web these days, there is a fine line between casually checking your social media pages and having a full-blown Internet addiction.If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction.__1__ Admit you are at risk of an addiction.More and more people in the world are becoming addicted to the Internet.You are not the only one with this problem, and it is becoming more and more common and more and more well-known.__2__ Set aside limited time for computer use.Make sure not to turn it on too many times a week.If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day.Try keeping the lid closed when you are not using it.__3__ If you have a desktop PC, try not to go near it or put something over it like a sheet.Call people instead of sending instant messages or texts.If you are free on weekends, call friends and ask them to go outside.This will distract you from the computer.__4__ Use an alarm clock or timer.Before using your computer, decide on a time limit such as 30 minutes.Set the clock or timer and make sure that you get off the computer when the time is up.Alternatively create a shutdown timer on your desktop.__5__ A.Make a small list of what you want to do within that time.B.When the computer is not looking at you, you are less likely to use it.C.This can be programmed to shut down your computer after the set time.D.Luckily, there are ways to avoid living your life in front of the computer.E.This will stop you from using the Internet so often or going on to another page.F.If you have a problem on weekdays, phone your friends or ask for help in person.G.Do not be embarrassed;find others with the same problem and help each other beat it.答案與解析 【文章大意】 網(wǎng)癮會(huì)給人們的生活帶來很大的影響，本文就如何避免網(wǎng)癮提出了建議。1．D 上文談到網(wǎng)癮會(huì)導(dǎo)致你對(duì)生活的其他方面失去興趣，下文的幾條建議則是有關(guān)如何避免網(wǎng)癮的，D項(xiàng)對(duì)全文起著承上啟下的作用。

2．G 本段的主旨是“Admit you are at risk of an addiction”，再結(jié)合本段講述的“越來越多的人有網(wǎng)癮，這是一個(gè)普遍現(xiàn)象”可知，選G項(xiàng)“不要覺得不好意思，找到和你一樣有網(wǎng)癮的人，互相幫助去戰(zhàn)勝網(wǎng)癮”。

3．B 根據(jù)空前的“Try keeping the lid closed when you are not using it”可知，作者建議你不用電腦時(shí)，把它合上，故選B項(xiàng)“看不到電腦時(shí)，你用它的可能性就小”。

4．F 本段的主題是“給朋友打電話而不是在網(wǎng)上發(fā)信息”，上文的“call friends and ask them to go outside”與F項(xiàng)中的“phone your friends or ask for help in person”，還有上文的“on weekends”與F項(xiàng)中的“on weekdays”前后呼應(yīng)。

5．C 本段的主題是“Use an alarm clock or timer”，作者建議使用鬧鐘或定時(shí)器來限制上網(wǎng)的時(shí)間，空前的“shutdown timer”與C項(xiàng)中的“shut down your computer after the set time”相對(duì)應(yīng)。

Ⅲ.語法填空

(2017·石家莊模擬考試)Dogs are __1__ very popular pet.Most of them just live with their families.But some dogs have very special jobs __2__(do).A group of dogs __3__(know)as “Therapy Dogs”.These dogs are family pets with special training, __4__ allows them to go into public buildings and comfort people __5__ need.The dogs are trained to be calm and quiet.Loud noises and unfamiliar places don't frighten them.They enjoy spending time with people.Some therapy dogs go into places, such as hospitals and nursing homes.When the dogs visit the patients, the patients are cheered up.They have fun __6__(pet)the dogs and look forward to their visits.The dogs help to brighten their day.Therapy dogs can improve people's health as well.Studies show that when people pet animals, their blood __7__(press)and heart rates go down.They are calmer and __8__(they)mood improves.Other therapy dogs work in schools and libraries.They serve as warm and caring __9__(friend)to children, but they also do __10__(much).In one town in California, therapy dogs have become children's reading buddies.The dogs make a great audience.The children look forward to reading to the dogs, and the dogs love the attention.答案與解析

【文章大意】 本文是一篇說明文，介紹了有著特殊用途的狗——治療犬。它們能給病人帶來心理上的安慰，能成為孩子的朋友。

1．a(chǎn) 考查冠詞。依據(jù)本句中的“very popular pet”可知，此處應(yīng)用不定冠詞，表示泛指。

2．to do 考查固定用法。本句中應(yīng)用不定式作后置定語，have sth.to do表示“要做某事”。

3．a(chǎn)re known 考查時(shí)態(tài)、語態(tài)和主謂一致。分析句子結(jié)構(gòu)可知，本句話缺少謂語動(dòng)詞，“a group of＋名詞復(fù)數(shù)”作主語時(shí)，謂語動(dòng)詞用復(fù)數(shù)，dogs與know是動(dòng)賓關(guān)系，此處描述的是一般情況，因此用一般現(xiàn)在時(shí)的被動(dòng)語態(tài)。

4．which 考查定語從句。這是一個(gè)非限制性定語從句，先行詞為“special training”。

5．in 考查介詞。由句意可知，這些治療犬可以到公共場(chǎng)所安撫那些需要幫助的人。in need表示“在困難時(shí)，在危難之中”，為固定搭配。

6．petting 考查非謂語動(dòng)詞。have fun(in)doing sth.表示“做某事有樂趣”。7．pressure 考查名詞。分析句子結(jié)構(gòu)可知，此處應(yīng)用名詞，blood pressure表示“血壓”。

8．their 考查代詞。修飾名詞mood要用形容詞性物主代詞，故用their。9．friends 考查名詞的數(shù)。根據(jù)句子的主語They可知，此處用名詞復(fù)數(shù)。

10．more 考查比較級(jí)。句中的but暗示這些狗對(duì)孩子來講不僅僅是朋友，它們會(huì)做得更多。

A

One summer my friend and I decided to go to Italy for a holiday and we decided to travel there without going through a travel agency.You know, you would be submerged(淹沒)in crowds of tourists and lose lots of opportunities to get familiar with the country more closely.We started to think over our trip and managed to come up with a free tour of Italy.The trip was not very long but it was still very impressive.We look forward to going there again!Of course, we spent lots of time arranging the trip, but it was well worth it!Of course I was afraid that something would go wrong and I was especially anxious about my visa, but everything went quite smoothly in the end.The most difficult part was getting a visa without an invitation.In the Italian consulate(領(lǐng)事館), one must hand in some official paper proving that one has a hotel booked for oneself in order to get the visa.Then we had to solve the ticket problem.Airlines often sell cheap tickets and we bought ours far in advance.The next step was to book a hotel.We finally booked a hotel about 30 km away from the heart of Rome and it was the perfect choice for our trip.Every day we took a train that carried us to the heart of Rome.Our big house, which was

surrounded by the forest, was a rare place for the fresh air and absolute silence, beautiful views,hospitable(好客的)hosts, comfortable living conditions delighted us to no end.Besides this, we were very lucky that our mistress was Russian.She gave us a lot of advice that was of great use.She told us what transport to choose and where the best places to go.Don't be afraid to arrange your trip by yourself.It's not difficult!The only thing I'll say right now is that we really enjoyed travelling by ourselves.We walked with a map and a guide-book to wherever we wanted and we even met some of our fellow countrymen on the way just two or three times.So, if you're also planning a “single” trip, don't forget to take a Russian-Italian phrasebook as people in Italy prefer to speak in their native tongue.16．Why does the author want to go to Italy again?

A．He had a great time there.B．Italy has a lot of attractions.C．His friend invited him there.D．He didn't stay in Italy long enough.17．What does the author think was the hardest in preparing for his Italian trip?

A．Buying cheap airline tickets to Italy before the travelling.B．Getting a visa without an invitation from the Italian consulate.C．Booking a comfortable hotel on his own in Rome.D．Solving the ticket problem far in advance.18．In the fourth paragraph the author mainly explains________.A．the reason why he chose to live in the center of Rome

B．the reason why the hotel he booked was the right choice

C．what transport they chose to travel in their Italian trip

D．the reason why the mistress gave them some advice

19．Which of the following questions has NOT been answered in the passage?

A．Why did the author decide to go to Italy for a holiday for the first time?

B．Why did the author decide not to follow a travel agency?

D．What tools did the author use for his travelling?

20．From the text we can know the author________.A．enjoys travelling everywhere in the world

B．likes being accompanied by tour guides

D．met with a lot of his countrymen in Italy

Carbon monoxide(一氧化碳)poisoning kills and injures many people and animals around the world.The gas has been a problem since people first began burning fuels to cook food or to create heat.It is a problem in all parts of the world that experience cold weather.Carbon monoxide is called the silent killer because people do not know it is in the air.The gas has no color.It has no taste.It has no smell.It does not cause burning eyes.And it does not cause people to cough.But it is very deadly.It robs the body of its ability to use oxygen.Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues.It does this by linking with the blood.When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it.Damage to the body can begin very quickly from large amounts of carbon monoxide.How

quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in.Carbon monoxide poisoning has warning signs.But people have to be awake to recognize them.Small amounts of the gas will cause a person's head to hurt.He or she may begin to feel tired.The person may feel sick.The room may appear to be turning around.The person may have trouble

thinking clearly.People develop severe head pain as the amount of gas continues to enter their blood.They will begin to feel very tired and sleepy.They may have terrible stomach pains.Medical experts say carbon monoxide affects people differently.For example, a small child will experience health problems or die much quicker than an adult will.The general health of the person or his or her age can also be important.An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems.People with heart disease may suffer chest pains.They may begin to have trouble breathing.21．Why is carbon monoxide called the silent killer?

A．Because it tastes and smells good.B．Because it is not easily noticed.C．Because it kills and injures people.D．Because it always harm people.22．How does carbon monoxide harm people?

A．It makes people's blood unable to move.B．It decreases the amount of blood in the body.C．It makes body tissues full of blood.D．It makes the blood less able to carry oxygen.23．When people breathe in small amounts of the gas, they may ________.A．feel a little dizzy

B．suffer a severe headache

C．go around in the room

D．have a terrible stomachache

24．Which of the following about carbon monoxide poisoning is TRUE?

A．Adults are affected more seriously than children.B．Young people are more severely affected than old people.C．People in poor health may have more severe consequences.D．People with heart problem only suffer from chest pains.25．The purpose of the passage is to ________.A．warn people not to burn fuels to keep warm in the winter

B．list the damages that carbon monoxide brings to people

C．give advice on how to avoid carbon monoxide poisoning

D．introduce some knowledge about carbon monoxide poisoning

Ⅰ.1.B 由上下文可知，還是小孩子的“我”，在圣誕節(jié)來臨時(shí)應(yīng)該是收到禮物。

2．C 聯(lián)系上下文，此處表達(dá)的意思是別人問“我”收到了什么禮物。

3．C show up出現(xiàn)。

4．B 有了禮物在學(xué)校就不會(huì)感到難堪了。

5．B 聯(lián)系上下文，提到new house，選擇first。

6．B 聯(lián)系上下文，可了解作者當(dāng)時(shí)那種激動(dòng)的心情，所以應(yīng)該是突然她想到了那件讓她難忘的事情。

7．C 根據(jù)第一段中描述那次圣誕節(jié)禮物給作者的感受和作者此刻的心情，她認(rèn)為送圣誕節(jié)禮物讓孩子們感到自己的重要性。

8．B 此處表示“夠得著，能聯(lián)系上”。不能選擇A，因?yàn)樽髡卟豢赡苷J(rèn)識(shí)很多孩子。

9．C 從上一段可以推斷，是“我”想出了(came up with)一個(gè)計(jì)劃。

10．B 每個(gè)人都有屬于自己的禮物，所以作者的意思是給孩子們啟示：每個(gè)人都是特殊的，獨(dú)一無二的。

11．A 從下文的One, two, three.Open your presents！可知，在分發(fā)禮物時(shí)，“我”提醒每個(gè)人開始不要打開禮物。

12．C 根據(jù)下文的意思，此處表示大家等待的拆禮物的時(shí)刻到來了。

Ⅱ.A

本文是一篇游記，講述了作者和朋友的意大利之行。文章介紹了旅游前的準(zhǔn)備工作，如自己取得簽證，還有意大利的住宿條件，突出了自己策劃意大利之游的優(yōu)點(diǎn)以及感受。

16．A 推理判斷題。根據(jù)第二段The trip was not very long but it was still very impressive.We look forward to going there again！并結(jié)合第四段的內(nèi)容以及最后一段中的The only thing I'll say right now is that we really enjoyed travelling by ourselves.可知，意大利之行他們玩得很盡興，給他們留下了深刻的印象，所以想再去意大利，因此選A。

17．B 細(xì)節(jié)理解題。根據(jù)第三段的第一句The most difficult part was getting a visa without an invitation.可知，最難的事情是在沒有邀請(qǐng)函的情況下向意大利大使館申請(qǐng)簽證，因此選B。

A、C和D雖然文中都涉及了，但是都不符合題意。

18．B 段落大意題。根據(jù)第四段對(duì)旅館周圍環(huán)境、交通情況以及該旅館的介紹可知，作者在第四段主要講對(duì)旅館滿意的原因。

19．A 細(xì)節(jié)理解題。文章第一段第二句講述了他們不愿意隨旅行社出游的原因，B項(xiàng)提到了；文章第二、三兩段講述作者怎么去準(zhǔn)備他的出行的，所以C項(xiàng)提到了；根據(jù)最后一段的We walked with a map and a guide-book to wherever we wanted?可知D項(xiàng)提到了。縱觀全文，作者并沒有提到他首次去意大利旅游的原因。

20．C 推理判斷題。根據(jù)文章的主要內(nèi)容，尤其是第一段及最后一段的Don't be afraid to arrange your trip by yourself.可以推斷出應(yīng)該選擇C。其余選項(xiàng)沒有依據(jù)。

B

這是一篇科普類的文章。文章向我們介紹了一氧化碳的特性以及傷害人的原理及癥狀。

21．B 細(xì)節(jié)理解題。題干關(guān)鍵詞為called the silent killer。由文章第二段的 The gas has no color.It has no taste.It has no smell.It does not cause burning eyes.And it does not cause people to cough.可以看出，一氧化碳無色、無味、不刺激眼睛，也不會(huì)讓人咳嗽，也就是說它不容易被人發(fā)覺。故選B。

22．D 細(xì)節(jié)理解題。由第三段的Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues.可以看出，一氧化碳傷害人體的方式是：降低血液攜帶氧的能力。

23．A 細(xì)節(jié)理解題。倒數(shù)第二段向我們描述了人體吸入一氧化碳時(shí)的反應(yīng)：吸入少量時(shí)，Small amounts of the gas will cause a person's head to hurt.He or she may begin to feel tired.The person may feel sick.The room may appear to be turning around.The person may have trouble thinking clearly.只有A項(xiàng)所說的feel a little dizzy對(duì)應(yīng)The room may appear to be turning around.。

24．C 細(xì)節(jié)理解題。最后一段講述了不同的人以及不同狀況的人吸入一氧化碳后的反

應(yīng)，老人等身體健康狀況欠佳的人所受的影響會(huì)更大。注意，D項(xiàng)干擾性最大，但是suffer from chest pains只是癥狀之一，而不是唯一的癥狀。

25．D 推理判斷題。縱觀全文可以看出，文章向我們介紹了一氧化碳的特性以及它使人中毒的原理以及中毒后人體的反應(yīng)。故D項(xiàng)符合。

Ⅱ.閱讀理解

A

My hate for my mother caused me a lot of years of pain, but I finally realized that I was not hurting her.I was hurting myself and I was in bondage to her because I held her in my heart full of hate.God set me free from this when I forgave her.A couple of years ago I came face to face with my mother at my

grandmother's funeral.I told her about the changes in my life and I told her that I forgave her.I was able to tell her that I loved her.I am still separated from my oldest daughter, but she knows that I love her and that I made some wrong

choices.I am now raising three of my own children and my sister's child.When I look into the eyes of my sister's baby—who is now the same age as my oldest child was when I left her—I can see myself at that age.I know that Jesus forgives, as I am allowed to be the mother I never knew.Take a look at your life.There are things we dream of doing one day;there are things we wish we could forget.In the Bible, it says that Jesus came to make all things new.What would your life look like if you could start over with a clean slate?

Live with hope.If you are looking for peace, there is a way to balance your life.No one can be perfect, or have a perfect life.But every one of us has the opportunity to experience perfect grace through a personal relationship with God through his son, Jesus Christ.You can receive Christ right now by faith through prayer.Praying is simply talking to God.God knows your heart and is not so concerned with your words as he is with the attitude of your heart.Jesus Christ will come into your life, just as he promised.As you learn more about your relationship with God, and how much he loves you, you'll experience life to the fullest.16．From Paragraph 1, we can infer that ________．

A．the author still lives with her mother

B．the author has three children but the oldest one does not live with her

________．

A．she couldn't forgive herself for making so many mistakes

B．she is separated from her oldest daughter

C．she hasn't any belief in her life

D．she couldn't get rid of the hate for her mother

18．According to the author, which one is NOT true?

A．Not all of us can experience a perfect life.B．There are various situations in life.C．When we pray, God cares more about our attitude than our words.D．We should be grateful to God for his help.19．In writing this passage, the author intends to ________．

A．tell us a story about her and her children

B．show her regret to her mother

B．How to live a perfect life

C．The right attitude towards our life

B[2012·廣東卷]

I was blind, but I was ashamed of it if it was known.I refused to use a white stick and hated asking for help.After all, I was a teenage girl, and I couldn't bear people to look at me and think I was not like them.I must have been a terrible danger on the roads.Coming across me wandering through the traffic, motorists probably would have to step rapidly on their brakes.Apart from that, there were all sorts of disasters that used to occur on the way to and from work.One evening, I got off the bus about halfway home where I had to change buses, and as usual I ran into something.“I’m awfully sorry，”I said and stepped forward only to run into it again.When it happened a third time, I realized I had been apologizing to a lamppost.This was just one of the stupid things that constantly happened to me.So I carried on and found the bus stop, which was a request stop, where the bus wouldn't stop unless passengers wanted to get on or off.No one else was there and I had to try to guess if the bus had arrived.Generally in this situation, because I hated showing I was blind by asking for help, I tried to guess at the sound.Sometimes I would stop a big lorry and stand there feeling stupid as it drew away.In the end, I usually managed to swallow my pride and ask someone at the stop for help.But on this particular evening no one joined me at the stop;it seemed that everyone had suddenly decided not to travel by bus.Of course I heard plenty of buses pass, or I thought I did.But because I had given up stopping them for fear of making a fool of myself, I let them all go by.I stood there alone for half an hour without stopping one.Then I gaveup.I decided to walk on to the next stop.21.Thegirl refused to ask for help because she thought ________．

A．she might be recognized

B．a(chǎn)sking for help looked silly

C．she was normal and independent

D．being found blind was embarrassing

22.After the girl got off the bus that evening, she ________．

A．began to run

B．hit a person as usual

C．hit a lamppost by accident

D．was caught by something

23.At the request stop that evening, the girl ________．

A．stopped a big lorry

B．stopped the wrong bus

C．made no attempt to stop the bus

D．was not noticed by other people

24.What was the problem with guessing at the sound to stop a bus?

A．Other vehicles also stopped there.B．It was unreliable for making judgments.C．More lorries than buses responded to the girl.D．It took too much time for the girl to catch the bus.25.Finally the girl decided to walk to the next stop, hoping ________．

A．to find people there

B．to find more buses there

C．to find the bus by herself there

D．to find people more helpful there

課時(shí)作業(yè)(一)

Ⅰ.友情可貴，但到底什么樣的友誼才是真正的友誼？當(dāng)朋友執(zhí)迷不悟時(shí)，你能曉之以理，動(dòng)之以情，忍受誤會(huì)，堅(jiān)持下去，使朋友懸崖勒馬，那才是真正的友誼。

1．D 根據(jù)句中one of my best friends和happiness and sorrow及with可推斷出正確答案為D，表示“能夠分享快樂和悲傷的好朋友”；share sth with sb意為“與某人分享某物(事)”。

2．C 根據(jù)句中的talking一詞可判斷此句應(yīng)用句型sb spend(s)some time(in)doing sth“某人花時(shí)間做某事”。

3．B 由下文中提到的她父母不同意她和男友的交往可知，她想要會(huì)見男友，只能向父母撒謊；lie to sb about sth“就某事向某人撒謊”。

4．D 按照常理，她和這樣一個(gè)吸毒男友的交往是一件不正常、不自然的事情，但是作者的朋友仍然不顧一切地要和男友在一起，因此在她看來，這件事對(duì)于她自己來說是可以接受的。句意為：我無法相信她真的認(rèn)為和這樣的男朋友繼續(xù)交往是可以接受的。

5．C 結(jié)合上題解析，作者極力勸阻朋友和其男友交往，所以作者認(rèn)為她的朋友是自毀前程，讓她自己陷入麻煩之中，故本題正確答案為C。

6．A 根據(jù)上一題的解析和destroying一詞可知答案為A。get into trouble“陷入困境”。

7．D attitude towards sb“對(duì)某人的態(tài)度”。

8．C come close to doing 表示“差一點(diǎn)做某事”。全句意思是“我有好幾次差點(diǎn)告訴她我們的觀點(diǎn)相差太遠(yuǎn)，以至于我們無法維系我們的友誼。”

9．D 由上下文可知作者擔(dān)心她朋友的前途和她們之間的友誼，故正確答案為D, be concerned about sth表示“為某事?lián)摹薄?/p>

10．A 根據(jù)文章第一段的第二句可知“我們已經(jīng)是很久的朋友了”。

11．C 作為朋友，“我”相信她一定會(huì)珍視“我”(及“我”的建議)。

12．B 根據(jù)下文的from hurting herself，可知“我是在盡力挽救她不要傷害到她自己”。

13．D 由下文可推斷出作者此處表達(dá)的意思是“我相信我們之間的友誼會(huì)戰(zhàn)勝一切”。

14．A think about our talk表示“思考我們的談話”。

15．C break up with sb 表示“與某人分手(絕交)”。

Ⅱ.A

我們的生活每天都不一樣，不應(yīng)該帶有仇恨地去生活，而應(yīng)該把上帝裝在心中，放下仇恨，寬容自己，寬容別人，這樣才能生活得更美好。

16．C 推理判斷題。根據(jù)文中第一段后半部分可知，當(dāng)作者看到自己姐姐家孩子的眼睛時(shí)，就會(huì)想起和她一樣大時(shí)的自己，推出當(dāng)作者和姐姐孩子一起時(shí)，就會(huì)禁不住回憶起她的當(dāng)年，故選C項(xiàng)。

17．D 細(xì)節(jié)理解題。根據(jù)文中第一段第二句可知“我”傷害“我”自己并束縛著自己，因?yàn)椤拔摇毙睦锍錆M了對(duì)母親的憎恨，故選D項(xiàng)，因?yàn)樗荒芟龑?duì)母親的憎恨。

18．A 細(xì)節(jié)理解題。根據(jù)文中倒數(shù)第三段中“No one can be perfect, or have a

perfect life.”，可知沒有人能有絕對(duì)完美的生活，A選項(xiàng)中“Not all of us”與文中原意不符。

19．C 推理判斷題。文中通過自己憎恨母親到慢慢原諒母親逐步切入主題：沒有人能過絕對(duì)完美的生活，我們只有改變態(tài)度，尋求上帝的幫助才能改變生活，推出選C。

20．D 推理判斷題。文章一開始講了“我”對(duì)母親的憎恨，后來慢慢原諒了母親，然后開始點(diǎn)題講述上帝在我們生活中的作用，所以D項(xiàng)最合適。

B

這是一篇記敘文。表達(dá)盲人的生活觀。文章記敘了作者身為盲人，而不愿意讓別人知道，還不愿意向別人求助的事情。作者等公共汽車的事情使她體會(huì)到了有的時(shí)候還是需要?jiǎng)e人的幫助的。

21.D 細(xì)節(jié)理解題。由本文第一句(I was blind, but I was ashamed of it if it was known.)可知。

22.C 細(xì)節(jié)理解題。由第二段前三句，特別是第三句(When it happened a third time, I realized I had been apologizing to a lamppost.)可知。

23.C 細(xì)節(jié)理解題。根據(jù)最后一段可知，作者害怕攔不到車使自己難堪，所以放棄攔車。故選C。

24.B 推理判斷題。根據(jù)第三段I tried to guess at the sound.Sometimes I would stop a big lorry and stand there feeling stupid as it drew away.和第四段的But because I had given up stopping them for fear of making a fool of myself, I let them all go by.看出根據(jù)聲音來判斷車輛是不可靠的。故選B。

25.A 推理判斷題。從第四段I had given up stopping them for fear of making a fool of myself可知，她本人不想攔車了，又由第三段managed to swallow my pride and ask someone at the stop for help可知，她是決定找人幫忙了，而在本站沒有人，去下一站當(dāng)然就是希望在那里可以找到人幫忙。

?f?x－1?－f?x－2?，x>0?

________．

答案 －2

解析 由題知，f(3)＝f(2)－f(1)，f(2)＝f(1)－f(0)，則f(3)＝－f(0)＝－2.三、解答題

14．(2010·遼寧卷改編)設(shè)2a＝5b＝m＋2，求m的值．

ab答案

解析 a＝log2 m，b＝log5 m，代入已知，得logm 2＋logm 5＝2，即logm 10＝2，所以m＝10.1－x

15．已知函數(shù)f(x)＝－x＋log2.1＋x

(2)若x∈[－a，a](其中a∈(0,1))，試判斷函數(shù)f(x)是否存在最大值或最小值？ 答案(1)0

(2)有最小值f(a)＝－a＋log2

1－a1＋a

f(－a)＝a＋log21＋a1－a

1－x

解析(1)得函數(shù)的定義域是(－1,1)，1＋x1＋x1－x

又f(－x)＋f(x)＝log2＋log2log21＝0，1－x1＋x∴f(－x)＝－f(x)成立，∴函數(shù)f(x)是奇函數(shù)，11

∴f(－)＋f(＝0，20072007

f(－

11)＋f(＝0，20082008

1111∴f(－)＋f(－)＋f()＋f()＝0.***8(2)f(x)＝－x＋log2(1－x)－log2(1＋x)，－11∴f′(x)＝－1＋<0，?1－x?ln2?1＋x?ln2有最小值f(a)＝－a＋log2

(3)若對(duì)于區(qū)間[3,4]上的每一個(gè)x的值，不等式f(x)>()x＋m恒成立，求實(shí)數(shù)m的取值范

2圍．

解析(1)∵f(x)是奇函數(shù)，∴f(－x)＝－f(x)，11＋ax11－ax即loglog

2－1－x2x－1

1＋axx－111＋ax1x－1即loglog，∴＝，2－x－121－ax－x－11－ax化簡整理得(a2－1)x2＝0，∴a2－1＝0，a＝±1，經(jīng)檢驗(yàn)a＝－1，f(x)是奇函數(shù)，∴a＝－1.1x＋1(2)證明 由(1)得f(x)＝log，2x－1設(shè)1
