第Ⅰ卷·第三部分·閱讀理解

I was at a dance club when I was nineteen.One day my new friend walked with me to my car.It was a very cold night.As we were walking to my car, a man walked up to us.Behind him was a woman pushing a stroller with a child inside who was about 2 years old.The child had only a jacket on and it wasn’t zipped（拉上拉鏈）.The man began to tell us he wanted to borrow some money for the night and that he had a job but no place to live and was waiting for his first paycheck.He confirmed he could get our mailing address and mail the money back to us.The guy I was with reached into his pocket to give this man a $20 bill.As the man was extending his hand out to take the money, I put my hand on my new friend’s hand and said, “Can I talk to you for a minute?” I told him some people earned money by begging and that they always cheated those with soft hearts.And if they were 3 truly worried about their child being out in the cold, they would have at least zipped his jacket.My friend looked at me with disapproval and said, “Michael, I know there are some people out there that take advantage of others.I also know some people out there that are one paycheck away from being homeless.If I gave $20 to 10 people and only one of them really needed it and used it for the right thing, it was worth it.” I am now thirty-seven years old and have never forgotten what he said to me.I don’t even remember his name now.But I do remember that this experience changed my perspective（觀點(diǎn)）.56.When the story happened, the author ____.A.was in his late thirties B.served as a car repairman C.had much money in his pocket D.was walking towards his car with his friend 57.The underlined word “stroller” in the first paragraph probably means “____”.A.a big bookcase B.a large box C.a baby carriage D.a small bicycle 58.Why did the author think the man was telling a lie?

Language experts say that spoken English was almost the same in the American colonies（殖民地）and Britain.Americans began to change the sound of their speech after the Revolutionary War in 1776.They wanted to separate themselves from the British in language as they separated themselves from the British government.Some American leaders proposed（提議）major changes in the language.Benjamin Franklin wanted a new system of spelling.His reforms were rejected.But his ideas influenced others.One was Noah Webster.Webster wrote language books for schools.He thought Americans should learn from American books.He published his first spelling book in 1783.Webster published The American Dictionary of the English 5 Language in 1828.It established rules for speaking and spelling the words used in American English.Webster believed that British English spelling rules were too complex.So he worked to establish an American version of the English language.For example, he spelled the word “center” “c-e-n-t-e-r” instead of the British spelling, “c-e-n-t-r-e”.He spelled the word “honor” “h-o-n-o-r” instead of “h-o-n-o-u-r” as it is spelt in Britain.Noah Webster said every part of a word should be spoken.That is why Americans say “sec-re-ta-ry” instead of “sec-re-t-ry” as the British do.Webster’s rule for saying every part of a word made American English easier for immigrants（移民）to learn.The different languages of the immigrants who came to the United States also helped make American English different from British English.Many foreign words and expressions became part of English as Americans speak it.Sometimes Americans and British people do not understand each other because of different word meanings.For example, a “jumper” in Britain is a sweater.In the United States, it is a kind of dress.French fried potatoes in the United States are called “chips” in Britain.All these differences led British writer George Bernard Shaw to joke that Britain and America are two countries separated by the same language.64.Americans wanted to speak a different kind of English because____.A.the British government didn’t allow them to speak British English B.they wanted to show they were independent of the UK C.they thought British English was hard to learn and speak D.they were advised by some language experts to create their own language 65.It seemed that Benjamin Franklin____.A.was happy to see his reform carried out in America B.wrote a dictionary of American English C.was influenced by Noah Webster in the 18th century D.had intended to change the spelling of British English 66.We know from the passage that ____.A.Webster’s rule was good for immig-rants B.Franklin was influenced by Webster’s idea

C.Webster’s dictionary was published in 1783

D.immigrants preferred British English 67.What do we know from George Bernard Shaw’s words?

A.It is right that different countries have different languages.B.American English is better than British English.C.Although there are differences, American and British English are still the same.D.The English language separates the United States from Britain.6 Not everyone wants to take medications forever.In my research, people with diabetes(糖尿病)who eat a totally plant-based, low-fat diet will lose weight, reduce their cholesterol(膽固醇)and improve their blood sugar better than those on a portion(部分)control diet.You can use diet to change the condition, but if you return to your old habits, it will come right back.— Neal D.Barnard, MD, President, Physicians Committee for Responsible Medicine Diet and exercise have the biggest impact, and the best diet is high in fiber and low in what can be slowly changed into sugar.The American Diabetes Association recommends eating about 30 grams of fiber a day, but studies suggest that eating up to 50 grams provides significant benefits, because fiber lowers insulin（胰島素）and cholesterol levels.— Dwight McKee, MD, Aptos, California Being overweight is a main cause of type 2 diabetes.Exercising is the key to changing the condition.As you change your diet, aim to burn 300 calories a day through exercise.If you have to, work out twice a day if you can’t do it in one shot.And as you get fitter, gradually increase your exercise time.— Joel Fuhrman, MD, Flemington, New Jersey Diabetes is a disease, not a moral failing.Lifestyle changes can make it better, but that doesn’t necessarily mean horrible lifestyle choices cause it.If diet and exercise don’t help, we try a drug that doesn’t cause weight gain.If that still doesn’t work, we add more medications.Type 2 diabetes is generally a progressive disease.Even if you do everything right, you may need to increase your medicine over time.— Robin Goland, MD, Columbia University Medical Center, New York 68.The phrase “your old habits” in Par-agraph 1 probably means ____.A.taking more medications to cure diabetes B.having a totally plant-based, low-fat diet C.having a portion control diet D.eating meat and sugar only 69.What can we learn from the passage? A.The higher cholesterol level is, the more serious diabetes is.B.What can be slowly changed into sugar must be high in fiber.C.One tends to eat more fiber when he has diabetes.D.Diabetes will always last a short period of time.70.Expert Robin Goland may probably think that____.A.improper lifestyles will cause dia-betes B.proper lifestyles may help treat dia-betes C.being overweight can cause diabetes D.people with diabetes should take medicine quickly 71.The passage is written mainly for ____.A.people with poor health

B.people with horrible lifestyles C.people with overweight problems D.people with type 2 diabetes

Some people say that friendship is the only channel through which human beings can ever experience the value of life.In our daily life, it is likely that you share some common interests with others — they may like the same sport, go to the same school or like the same kind of music as you do.Since you often meet them, they become your acquaintances(熟人).Although some people develop many acquaintances, only a few become their good friends in their lifetime because there are differences between acquaintances and friends.It is said that true friendship begins when someone knows what you are really like, but still likes you anyway.A true friend shows loyalty（忠誠(chéng)）from the very beginning of the relationship.A friend will go through challenges to help you without expecting anything in return.A“friend” today may probably become a “true friend” tomorrow when they get involved in unexpected circumstances(狀況)together with you — for example, when you are going through a difficult experience and your friend is there to help you out.However, some acquaintances might leave you when you badly need their help.At this time, you can experience what true friendship is.In our life, some people seem to go through life with plenty of friends.They may be funny or they may have a bright and pleasant personality.For these people, wherever they go, people seem to like them and welcome their company.But when they go through challenging life experiences, some of their friends are not there to help them.Therefore we can say some of their friends are not real friends and their friendship is just skin-deep.However, others seem to go through life with no friends at all.They like to be alone, to travel by themselves or to do their own thing.It’s a pity that few of these people find success in life because they have no friends.They lack the best gift in life — friendship.72.According to the passage, which of the following statements about acquain-tances is true? A.They have all of the same interests as you do.B.You seldom meet them in your life.C.They are sure to become your good friends.D.Not all of them can become your friends.73.According to the passage you may get to know the meaning of friendship better when you ____.A.go to the same school as your friend B.enjoy the same kind of music as your friend C.get into trouble D.see your friend often 74.We know from the passage that ____.A.it doesn’t matter whether one has friends or not

B.people with bright personality are easy to have friends C.people without friends are always unhappy D.it’s easier to lose a friend than to get one 75.What’s the writer’s attitude towards people without friends in their life? A.Interested.B.Angry.C.Hopeful.D.Regretful.第Ⅱ卷·第四部分·寫(xiě)作

Zhai Wanming has become famous in railway engineering.Zhai, born in 1963 in Jiangsu Province, has been focusing on research of the increasing of train speeds.In 1985 he graduated from Southwest Communication University and received a doctor’s degree there in 1992.Later, because of his outstanding contribution, he gained the Award of Chinese Youth Scientist.Serving as a specialist, Zhai did so much work in his field that his achievements have been successfully applied to more than 10 important engineering projects in Chinese railways.In my opinion, Zhai is a great scientist who has closely combined his studies with practice.We students should learn from his devotion to science and put our heart into our studies.21.A?？疾楣谠~用法。draw a conclusion為固定搭配，意為“得出結(jié)論”；“the universe”指宇宙，與the sun, the earth等等一樣指世界上獨(dú)一無(wú)二的東西，前面的冠詞用the；但本句中的“universe of his own”指的是 “他的個(gè)人世界”，形容詞little以輔音音素開(kāi)頭，所以前面用不定冠詞a。

22.B?？疾榍榫敖浑H。根據(jù)問(wèn)句 “Will you do me a favour and fetch some chalk?”可知是求助?！癏elp yourself”是招待客人用語(yǔ)，意為：請(qǐng)隨便用；“With pleasure.”用來(lái)回答別人的幫助或請(qǐng)求，意為：樂(lè)意幫忙；“Congratulations！”用于祝賀；“I’ve no idea.”意為：我不知道。

23.D?？疾閎lame用法。be to blame(for sth)對(duì)（壞事）負(fù)有責(zé)任。根據(jù)句意“是你而不是Lucy應(yīng)對(duì)這次事故負(fù)責(zé)”可知，謂語(yǔ)動(dòng)詞對(duì)應(yīng)的主語(yǔ)是you。C項(xiàng)中如果是should be blamed就正確了。

24.C?？疾槊~辨析。句意：眾所周知，人類(lèi)主要的特征是會(huì)思考。characteristic“特 10 征，特性”，符合句意；statistic“統(tǒng)計(jì)量”；application“應(yīng)用，用途”；function“作用，功能”。25.B?？疾閑nthusiastic 用法。amazed at“對(duì)??感到吃驚”；enthusiastic about “熱心于??”；absorbed in“專(zhuān)心于??”；responsible for“對(duì)??負(fù)責(zé)”句意：Nancy下個(gè)月將去華盛頓，但是她對(duì)去那不太感興趣。26.C。考查動(dòng)詞辨析。句意：政府上周向記者宣布創(chuàng)造一個(gè)大型商業(yè)中心的計(jì)劃。announce“宣布，通告”，符合句意。admit“承認(rèn)”；respond“回答”；instruct“命令，指示”。27.A?？疾楣潭ù钆?。contribute sth to...是固定短語(yǔ)，意為“向??捐獻(xiàn)，捐贈(zèng)”。句意：Professor Smith個(gè)人向?yàn)?zāi)區(qū)捐贈(zèng)了50萬(wàn)美元。

28.D。考查動(dòng)詞短語(yǔ)辨析。句意：在會(huì)議上，Jessica提出了一條深受在場(chǎng)的每個(gè)人歡迎的建議。put forward“提出”，符合句意。put though“完成，實(shí)現(xiàn)”；put down“記下”；put off“推遲，延期”。

29.B?？疾閟uspect用法。suspect sb of(doing)sth懷疑某人做某事。句意：那個(gè)名字叫David的人被懷疑在法庭上提供假證詞。

30.D?？疾槎陶Z(yǔ)辨析。句意：除了Filippo Inzaghi之外，意大利還有很多優(yōu)秀的足球明星名揚(yáng)全世界。apart from“除??之外”，符合句意。instead of“代替”；rather than“而不是”；in order to“為了”。

31.B?？疾檫^(guò)去分詞作定語(yǔ)。句意：暴露于外太空的微小的動(dòng)物能否活下來(lái)還不清楚。expose...to“暴露”。在本句中exposed to...是作tiny animals的后置定語(yǔ)。

32.A?？疾樾稳菰~辨析。句意：我的老板Mr Brown是一位MBA(工商管理碩士)，所以他采取了一種非常科學(xué)的管理方法。scientific“科學(xué)的”，符合句意。intelligent“智能的”；independent“獨(dú)立的”； technological“科技的”。33.D?？疾橥徽Z(yǔ)從句。分析句意可知，本題應(yīng)選擇同位語(yǔ)從句的引導(dǎo)詞，作idea的同位語(yǔ)；從句意義完整，并不缺少成分，因而用that來(lái)引導(dǎo)。句意：突然間我有個(gè)想法——我們要寫(xiě)一篇關(guān)于本地區(qū)野生生物的論文。

34.C?？疾閕nstruct用法。instruct sb to do sth命令/指示某人做某事。句意：這個(gè)公司里所有的人都依照指示交回了昨天做的調(diào)查。35.C?？疾檫^(guò)去分詞作表語(yǔ)。be+過(guò)去分詞作表語(yǔ)，表示一種狀態(tài)，其中的過(guò)去分詞相當(dāng)于形容詞。句意：那個(gè)小村莊——我的家鄉(xiāng)，三面環(huán)山。

36.B。根據(jù)上文的“I was busy all the time.”可推知, 作者的生活總是圍繞著丈夫和孩子。

37.C。根據(jù)連詞so 前的分句“My life always centred around my husband and children”尤其是nearly可以確定正確答案，“be stuck with...”意為：擺脫不了??，受困于；“我”的精力受困于此，即把主要精力都花費(fèi)在丈夫和孩子身上。

38.A。根據(jù)后句中的“over the phone”可推知，Judy是打電話過(guò)來(lái)。

39.D。由上文的“...she would join an oil painting class on Friday night.”以及下文的“...whether to join her or not...”可以確定作者此處并未答復(fù)Judy是否參加油畫(huà)班。

40.D。根據(jù)上文的“I hesitated to answer her immediately over the phone”可以確定，作者并不確定是否和Judy一起參加油畫(huà)班。

46.C。根據(jù)下文中的“We painted the most beautiful and ugly thing”可以確定，作者的作品中包含其所討厭的。

47.B。根據(jù)上文的“the most beautiful and ugly thing.”可知，作者可以把其思維中的一切事物繪畫(huà)出來(lái)。

48.D。根據(jù)句中的“I forget everything that worried me most”可以確定，此處應(yīng)表達(dá)作者有些時(shí)候“甚至”忘記了時(shí)間。

51.D。分析上文可以確定，作者從繪畫(huà)中收獲很多快樂(lè)，因而兩個(gè)分句間為轉(zhuǎn)折關(guān)系。52.B。由后面的“expresses his feelings”可以確定此處應(yīng)填“代表”。

53.A。根據(jù)后面的“I could sense the passion and the energy from his painting.”可以確定，此處表達(dá)作者在欣賞梵高作品時(shí)的收獲。

56.D。細(xì)節(jié)理解題。根據(jù)第一段的“I was at a dance club when I was nineteen.”可以排除A和B；C在文中并未提到；由“One day my new friend walked with me to my car”可以確定D正確。57.C。詞義猜測(cè)題。根據(jù) “pushing”以及 “with a child inside”可以確定“stroller”應(yīng)是指嬰兒坐的小推車(chē)。58.B。細(xì)節(jié)理解題。從第二段的“And if they were truly worried about their child being out in the cold, they would have at least zipped his jacket.”可知，這對(duì)夫妻對(duì)他們的孩子漠不關(guān)心，由此作者判斷他們?cè)谡f(shuō)謊。59.A。推理判斷題。根據(jù)第三段中作者的朋友所說(shuō)的“I also know some people out there that are one paycheck away from being homeless.”可以推斷出，作者的朋友認(rèn)為存在許多勉強(qiáng)生活的窮人。

【文章大意】我們網(wǎng)上交通學(xué)校的目的就是方便學(xué)生學(xué)習(xí)。學(xué)習(xí)時(shí)間由你掌握。如果你未學(xué)好，我們百分之百退還費(fèi)用。我們的費(fèi)用中并不包含隱藏的費(fèi)用，而且收費(fèi)在同類(lèi)學(xué)校中最低。

60.C。段落大意題。第一段從幾個(gè)方面提到了網(wǎng)上交通學(xué)校的優(yōu)勢(shì)（如No wasting gas driving to classrooms以及All you need is just your computer and an Internet connection.）。61.B。細(xì)節(jié)理解題。根據(jù)第二段中的“There’s NO HIDDEN FEES”以及“Everything is spelled out ahead?”可知該校并沒(méi)有隱藏的費(fèi)用，一切費(fèi)用都會(huì)提前通知學(xué)員。

62.C。細(xì)節(jié)理解題。根據(jù)第四段中的“We take great pride in the fact that...if you have any questions, you can get help from our Expert Service Team 24 hours a day, 365 days a year.”可以確定答案。

63.A。推理判斷題。本文是篇廣告，首先介紹了這個(gè)學(xué)校（與其他同類(lèi)學(xué)校相比的）一些優(yōu)勢(shì)，廣告最后的祈使句“Sign up today!”暗示了此廣告的目的?！疚恼麓笠狻坑⑹接⒄Z(yǔ)與美式英語(yǔ)在單詞拼寫(xiě)以及意思上有所差別。大量講不同種語(yǔ)言的移民的涌入，也使得美式英語(yǔ)不同于英式英語(yǔ)。64.B。細(xì)節(jié)理解題。根據(jù)第一段中“They wanted to separate themselves from the British in language as they separated themselves from the British government.”可知，美國(guó)人想要獨(dú)立，他們想講另外一種英語(yǔ)。65.D。推理判斷題。根據(jù)第二段中“Benjamin Franklin wanted a new system of spelling.” 可知答案。

66.A。推理判斷題。根據(jù)第四段中“Webster’s rule for saying every part of a word made American English easier for immigrants to learn.”可知，Webster的規(guī)定對(duì)移民來(lái)說(shuō)是有好處的。67.C。細(xì)節(jié)理解題。根據(jù)關(guān)鍵詞“two countries, the same language”可知，George Bernard Shaw認(rèn)為，盡管美式英語(yǔ)和英式英語(yǔ)有所區(qū)別，但是它們?nèi)耘f是同一種語(yǔ)言。

【文章大意】隨著糖尿病日益受到關(guān)注，美國(guó)的幾位專(zhuān)家也相應(yīng)推出了自己的研究結(jié)果；尤其是關(guān)于Ⅱ型糖尿病，專(zhuān)家們提出了相應(yīng)的治療建議。

68.C。細(xì)節(jié)理解題。第一段主要講述專(zhuān)家Neal D.Barnard通過(guò)研究發(fā)現(xiàn)，嚴(yán)格的素食習(xí)慣能比部分地控制飲食習(xí)慣對(duì)治療糖尿病更有利?？梢钥闯?，“your old habits”是指素食以前的舊習(xí)慣，即a portion control diet。

69.A。細(xì)節(jié)理解題。根據(jù)第一段“...reduce their cholesterol(膽固醇)and improve their blood sugar better than...”和第二段 “...because fiber lowers insulin and cholesterol levels.”可知，膽固醇含量降低證明糖尿病癥狀得到了改善,而A項(xiàng)從相反的一面說(shuō)明了這一點(diǎn)。

70.B。細(xì)節(jié)理解題。根據(jù)第四段中的“Lifestyle changes can make it better, but that doesn’t necessarily mean horrible lifestyle choices cause it.”可知正確答案。71.D。推理判斷題。閱讀全文可知，這些專(zhuān)家的研究結(jié)果均是針對(duì)糖尿病患者，尤其是關(guān)于Ⅱ型糖尿病，專(zhuān)家們提出了相應(yīng)的治療建議。

【文章大意】本文主要講述了熟人和朋友之間是有區(qū)別的，熟人不一定都會(huì)變成好朋友，生活中不能缺少朋友，朋友就是那個(gè)在你有困難的時(shí)候一起共渡難關(guān)的人。72.D。細(xì)節(jié)理解題。根據(jù)第一段中“Although some people develop many acquaintances, only a few become their good friends in their lifetime because there are differences between acquaintances and friends.”可知，熟人不一定全都成為朋友。73.C。細(xì)節(jié)理解題。根據(jù)第二段中“for example, when you are going through a difficult experience and your friend is there to help you out...At this time, you can experience what true friendship is.”可知答案。

74.B。推理判斷題。根據(jù)第三段中“In our life, some people seem to go through life with plenty of friends.They may be funny or they may have a bright and pleasant personality...welcome their company.”可推出答案。75.D。推理判斷題。根據(jù)最后一段中“It’s a pity that few of these people find success in life because they have no friends.”可以推出，作者為那些沒(méi)有朋友的人感到遺憾。

A OTTAWA — Canada’s western city of Calgary is the world’s best city when it comes to healthy living, local press reported Monday.According to an international survey by Mercer Human Resource Consulting, a London-based consulting firm, Calgary was put at the top of a list of 144 cities.It scored 121 points, just above Honolulu’s score of 120.Helsinki（赫爾辛基，芬蘭首都）and Ottawa followed at 119.5 and 118.5 respectively.Three other Canadian cities came in the top 20.Montreal and Vancouver tied for ninth and Toronto came in at 18th.The scores are based on air pollution levels, availability and quality of hospitals and medical supplies, as well as the efficiency of waste removal and sewage systems.3

In America, the lowest scoring city was Atlanta, which was ranked 76th.Athens was the lowest scoring city in Western Europe, ranking 120th because of its air pollution.London was ranked 59th.1.How many Canadian cities are in the top 20? A.3.B.4.C.5.D.6.2.Which of the following is NOT taken into account when the cities were scored? A.Weather conditions.B.Air quality.C.Waste removal.D.Medical supplies.3.Among the following cities, which is the lowest scoring one? A.Atlanta.B.Athens.C.London.D.Helsinki.B Canada is one of the few nations in the world that have two official languages：English and French.There are 10 provinces in the country but only one of these—Quebec is known as “French Canada”.This is because it was founded by French explorers while British adventurers discovered the rest.Canada left the British empire in 1867 to become an independent country，and English and French have become the official languages ever since.Most people speak English as their first language and the two national television networks broadcast in English throughout the country.Apart from in Quebec and a few places on the east coast，F(xiàn)rench television is very rare.The same goes for traffic signs and menus，for example，outside of Quebec，there are only a few places where you’ll see traffic signs in French.In restaurants，it’s almost impossible to find French on the menu unless you are in the heartland of French Canada.However，it is claimed by law thay all products sold in Canada must have labels and instructions in both languages.In Canada’s English speaking provinces，official bilingualism(雙語(yǔ))means that students can choose to complete a special French language course.Under this programme，they are taught most of their subjects in French.If a student begins the course in kindergarten or Grade One，it is likely that all their lessons will be in French.However，if they start at junior high school，25 percent of the teaching will continue to be in English.4.How many provinces are there in Canada? A.Ten.B.Nine.C.Eleven.D.Two.5.Which country controlled Canada before its independence? A.France.B.Britain.C.America.D.Germany.6.Where can you watch French television programmes? A.Only in Quebec.B.In Quebec and a few other places.C.From the two national television networks.D.All over Canada.7.What about the education in Canada? A.In English speaking provinces only English courses are offered there.B.If you choose a special French language course，most of the subjects are taught in French.C.The courses in primary school are all taught in English.D.Most of the courses in junior high schools are taught in English.8.Which of the following sentences is right? A.English is the only official language，though French is also spoken there.B.The two national television networks broadcast both in English and French.C.All products sold in Canada must，by law，have labels and instructions in both English and French.D.The lessons in kindergarten or Grade One are likely to be only in English.第2課時(shí)reading 5 基礎(chǔ)練習(xí)

I was at a dance club when I was nineteen.One day my new friend walked with me to my car.It was a very cold night.As we were walking to my car, a man walked up to us.Behind him was a woman pushing a stroller with a child inside who was about 2 years old.The child had only a jacket on and it wasn’t zipped（拉上拉鏈）.The man began to tell us he wanted to borrow some money for the night and that he had a job but no place to live and was waiting for his first paycheck.He confirmed he could get our mailing address and mail the money back to us.The guy I was with reached into his pocket to give this man a $20 bill.As the man was extending his hand out to take the money, I put my hand on my new friend’s hand and said, “Can I talk to you for a minute?” I told him some people earned money by begging and that they always cheated those with soft hearts.And if they were truly worried about their child being out in the cold, they would have at least zipped his jacket.My friend looked at me with disapproval and said, “Michael, I know there are some people out there that take advantage of others.I also know some people out there that are one paycheck away from being homeless.If I gave $20 to 10 people and only one of them really needed it and used it for the right thing, it was worth it.” I am now thirty-seven years old and have never forgotten what he said to me.I don’t even remember his name now.But I do remember that this experience changed my perspective（觀點(diǎn)）.41.When the story happened, the author ____.A.was in his late thirties 2 B.served as a car repairman C.had much money in his pocket D.was walking towards his car with his friend 42.The underlined word “stroller” in the first paragraph probably means “____”.A.a big bookcase B.a large box C.a baby carriage D.a small bicycle 43.Why did the author think the man was telling a lie? A.His expression was strange.B.He didn’t care for the baby at all.C.He said he had a job.D.He gave the author his mailing address.44.According to the author’s new friend, some people ____.A.were poor and about to be homeless B.often wished to have no paycheck C.weren’t out of work but they said they were D.were always making fun of others 45.We can infer the author could learn from the experience that ____.A.one should be very kind to everyone B.anybody has a time when he needs help C.one should do whatever is worthy actively D.one should keep away from those poor people B 難度：★★ Not everyone wants to take medications forever.In my research, people with diabetes(糖尿病)who eat a totally plant-based, low-fat diet will lose weight, reduce their cholesterol(膽固醇)and improve their blood sugar better than those on a portion(部分)control diet.You can use diet to change the condition, but if you return to your old habits, it will come right back.— Neal D.Barnard, MD, President, Physicians Committee for Responsible Medicine Diet and exercise have the biggest impact, and the best diet is high in fiber and low in what can be slowly changed into sugar.The American Diabetes Association recommends eating about 30 grams of fiber a day, but studies suggest that eating up to 50 grams provides significant benefits, because fiber lowers insulin（胰島素）and cholesterol levels.— Dwight McKee, MD, Aptos, California Being overweight is a main cause of type 2 diabetes.Exercising is the key to changing the condition.As you change your diet, aim to burn 300 calories a day through exercise.If you have to, work out twice a day if you can’t do it in one shot.And as you get fitter, gradually increase your exercise time.— Joel Fuhrman, MD, Flemington, New Jersey Diabetes is a disease, not a moral failing.Lifestyle changes can make it better, but that doesn’t necessarily mean horrible lifestyle choices cause it.If diet and exercise don’t help, we try a drug that doesn’t cause weight gain.If that still doesn’t work, we add more medications.Type Ⅱ diabetes is generally a progressive 3 disease.Even if you do everything right, you may need to increase your medicine over time.— Robin Goland, MD, Columbia University Medical Center, New York 46.The phrase “your old habits” in Paragraph 1 probably means ____.A.taking more medications to cure diabetes

B.having a totally plant-based, low-fat diet C.having a portion control diet D.eating meat and sugar only 47.What can we learn from the passage? A.The higher cholesterol level is, the more serious diabetes is.B.What can be slowly changed into sugar must be high in fiber.C.One tends to eat more fiber when he has diabetes.D.Diabetes will always last a short period of time.48.According to Joel Fuhrman, ____.A.eating less won’t lead to type 2 diabetes B.exercise plays an important role in treating diabetes C.changing diet is the best way to treat diabetes D.people with diabetes should exercise twice a day regularly 49.Expert Robin Goland may probably think that ____.A.improper lifestyles will cause diabetes B.proper lifestyles may help treat diabetes C.being overweight can cause diabetes D.people with diabetes should take medicine quickly 50.The passage is written mainly for ____.A.people in poor health

B.people with horrible lifestyles C.people with overweight problems D.people with type 2 diabetes C 難度：★★★ Language experts say that spoken English was almost the same in the American colonies（殖民地）and Britain.Americans began to change the sound of their speech after the Revolutionary War in 1776.They wanted to separate themselves from the British in language as they separated themselves from the British government.Some American leaders proposed（提議）major changes in the language.Benjamin Franklin wanted a new system of spelling.His reforms were rejected.But his ideas influenced others.One was Noah Webster.Webster wrote language books for schools.He thought Americans should learn from American books.He published his first spelling book in 1783.Webster published The American Dictionary of the English Language in 1828.It established rules for speaking and spelling the words used in American English.Webster believed that British English spelling rules were too complex.So he worked 4 to establish an American version of the English language.For example, he spelled the word “center” “c-e-n-t-e-r” instead of the British spelling, “c-e-n-t-r-e”.He spelled the word “honor” “h-o-n-o-r” instead of “h-o-n-o-u-r” as it is spelt in Britain.Noah Webster said every part of a word should be spoken.That is why Americans say “sec-re-ta-ry” instead of “sec-re-t-ry” as the British do.Webster’s rule for saying every part of a word made American English easier for immigrants（移民）to learn.The different languages of the immigrants who came to the United States also helped make American English different from British English.Many foreign words and expressions became part of English as Americans speak it.Sometimes Americans and British people do not understand each other because of different word meanings.For example, a “jumper” in Britain is a sweater.In the United States, it is a kind of dress.French fried potatoes in the United States are called “chips” in Britain.All these differences led British writer George Bernard Shaw to joke that Britain and America are two countries separated by the same language.51.Americans wanted to speak a different kind of English because____.A.the British government didn’t allow them to speak British English B.they wanted to show they were independent of the UK C.they thought British English was hard to learn and speak D.they were advised by some language experts to create their own language 52.It seemed that Benjamin Franklin ____.A.was happy to see his reform carried out in America B.wrote a dictionary of American English C.was influenced by Noah Webster in the 18th century D.had intended to change the spelling of British English 53.We know from the passage that ____.A.Webster’s rule was good for immigrants B.Franklin was influenced by Webster’s idea C.Webster’s dictionary was published in 1783 D.immigrants preferred British English 54.According to the fifth paragraph, which of the following is TRUE? A.The Americans and the British have no trouble understanding each other.B.American English has got new words from British English.C.Immigrants have a strong feeling of independence in the United States.D.Many new words came into American English because of immigrants.55.What do we know from George Bernard Shaw’s words? A.It is right that different countries have different languages.B.American English is better than British English.5 C.Although there are differences, American English and British English are still the same language.D.The English language separates the United States from Britain.第二節(jié) 信息匹配（共5小題；每小題2分，滿分10分）閱讀下列應(yīng)用文及相關(guān)信息，并按照要求匹配信息。以下是一些招收國(guó)際志愿者的信息： A.Volunteers on Straw Project We are looking for volunteers to help out with Straw Project this summer.We are building other houses besides Straw Project.Through their help, volunteers will get a better idea of how to build their own houses in the future.This will be valuable hands-on experience.For further information, click.B.Teaching and recreational activities for mentally handicapped children Volunteers will be involved in teaching, playing, cooking and feeding kids in a home for mentally handicapped children.There will be cultural presentations to present volunteers’ countries and cultures.Volunteers will be free to choose presentation methods like story telling, singing, dancing, or giving speeches.For more details, please visit:.C.FREE Dental Cleaning SAIT Dental Assisting PDM is looking for patients(between the ages of 12-35)who are interested in having their teeth cleaned.It is FREE!Do you know anyone who might be interested?

When was it formed then? All these interesting things are just like some forces pushing me to be a scientist, as I want to know the answers to all these questions.I want to be a scientist because scientists are great.They are respected and admired by others.Most of us appreciate their achievements.Admittedly, unlike the people doing business, scientists don’t have the chance to earn “big” money within a 7 short time.However, in my mind, being a scientist is much more challenging than being a businessman!All these make me want to be a scientist.[寫(xiě)作內(nèi)容] 1.以約30個(gè)詞概括上文的要點(diǎn)；

Curiosity about everything has made the author want to be a scientist since his childhood.And the idea that being a scientist is great and challenging makes him decide to be an excellent scientist.All the scientists have some qualities in common.First, a scientist should be interested in things around him, which in turn enables him to look at things from a special angle.Second, he should have a professional knowledge of the subject he is interested in and should have his own style of understanding of the area.With the professional knowledge and understanding, he will have the ability to contribute 8 to society.Being creative is another important quality for a scientist.From many stories of famous scientists, we can see that they like to solve problems in a new and special way.All in all, being curious, professional and creative in a certain area may make people be scientists.21.B。根據(jù)下文“I don’t mind admitting that I’m afraid to take this bear.”可知，Ali很害怕，所以應(yīng)該是很“緊張地”和他的朋友說(shuō)話。

22.C。根據(jù)下文“...the whole affair from the tree”可知，他快速地爬到了樹(shù)上。23.A。熊越來(lái)越近，根據(jù)下文他的槍走火沒(méi)有射中目標(biāo)可知，這里應(yīng)該是越來(lái)越怕。scared“害怕的”。

24.B。既然是很害怕那么當(dāng)時(shí)他一定是在“顫抖”（tremble）。25.D。他還沒(méi)有來(lái)得及瞄準(zhǔn)目標(biāo)，槍就走火了。

26.C。根據(jù)前面的“went off”可知，他“沒(méi)有擊中目標(biāo)”(miss the target)。27.D。此處說(shuō)的是：Hasan想起熊不碰死人的事情。

28.C。根據(jù)上文“bears never touch a dead body”可知，熊不碰死人，所以他是想要裝死，即 “屏住呼吸”（hold one’s breath）。

29.A。當(dāng)這個(gè)事件發(fā)生的時(shí)候Ali一直在樹(shù)上“觀看”（watch）。

30.A。熊走開(kāi)了沒(méi)有傷害到Hasan，所以Ali從樹(shù)上下來(lái)，祝賀Hasan 能夠“死里逃生”。31.As。考查定語(yǔ)從句關(guān)系代詞。as引導(dǎo)的定語(yǔ)從句可以置于句首，有“正如”之意。“As their name suggests，...”可以理解為“顧名思義，??”。

32.intended?？疾榉侵^語(yǔ)動(dòng)詞。分析句子結(jié)構(gòu)可知，tools與intend為被動(dòng)關(guān)系，故用intend的過(guò)去分詞形式intended作tools的定語(yǔ)，相當(dāng)于 “which are intended for...”。33.With?？疾榻樵~。此處的“With a digital camera which is built in them”為復(fù)合結(jié)構(gòu)，在該句中作狀語(yǔ)。34.convenience?？疾樵~形變化。分析該句的結(jié)構(gòu)可知，appreciate后缺少賓語(yǔ)，故使用convenient的名詞形式convenience。appreciate their convenience意為“欣賞它們的方便”。

35.a?？疾楣谠~。threat為可數(shù)名詞，在此處為泛指，故填不定冠詞a。句意為“但是，我們或許沒(méi)有意識(shí)到濫用拍照手機(jī)會(huì)對(duì)我們的隱私構(gòu)成嚴(yán)重威脅”。

36.others。考查代詞。由句意可知，我們是與“其他人”分享照片，所以others符合句意。

37.embarrassed。feel embarrassed意為“感到窘迫”。embarrassed在此處作feel的表語(yǔ)。

38.But?？疾檫B詞。上文陳述了當(dāng)我們的朋友在用手機(jī)給我們拍照時(shí)我們不會(huì)感到尷尬或不安，下文則說(shuō)在這種情況下，我們的隱私遭到侵犯，由此可知，上下文應(yīng)該為轉(zhuǎn)折關(guān)系，而空格后沒(méi)有逗號(hào)，故but符合句意。

39.worse。考查形容詞比較級(jí)。句意為“更糟糕的是，一些人可能違背我們的意愿為我們拍照??”。what’s worse意為“更為糟糕的是??”。40.that?？疾槊~性從句引導(dǎo)詞。本句中it為形式主語(yǔ)，真正的主語(yǔ)為that所引導(dǎo)的主語(yǔ)從句。

47.A。細(xì)節(jié)理解題。根據(jù)第一段“...reduce their cholesterol(膽固醇)and improve their blood sugar better than...”和第二段 “...because fiber lowers insulin and cholesterol levels.”可知，膽固醇含量降低證明糖尿病癥狀得到了改善,而A項(xiàng)從相反的一面說(shuō)明了這一點(diǎn)。48.B。細(xì)節(jié)理解題。第三段中Joel Fuhrman所提建議的中心內(nèi)容是加強(qiáng)鍛煉（Exercising is the key to changing the condition.），所以B正確；A項(xiàng)的說(shuō)法過(guò)于絕對(duì)；根據(jù)“As you change your diet, aim to burn 300 calories a day through exercise.”可以排除C；最后一句“If you have to, work out twice a day if you can’t do it in one shot...” 可以排除D。
