I ran to my mom for 36 but instead of taking me to a doctor, my mom set my hand 37 .After wrapping my hand with several layers of cotton, then soaking it in wine, she put a chopstick into my mouth, and lit the cotton. Heat quickly went through the cotton and began to roast my 38 . The sharp pain made me want to scream, but the chopstick 39 it. All I could do was watch my hand burn - one minute, then two minutes - 40 mom put out the fire.At that time there was no doctor available my mother could bring me to see about my spider bite.For those who study biology, you may have grasped the science 41 my mom's cure: heat deactivates (使不活跃) proteins, and a spider's venom, (毒液) is 42 a form of protein. It's 43 how that folk remedy actually includes basic biochemistry, isn't it? But I am a PhD student inbiochemistry at Harvard. I now know that better, less 44 and less risky treatments existed. So I can't help but ask myself why I didn't 45 one at that time.Now I am happy to report that my hand is fine. But this question remains, and I continue to be troubled by the unequal 46 of scientific knowledge throughout the world. Despite the knowledge we have accumulated, we haven't been so 47 in deploying (配置) it to where it's needed most. We constantly see these problems of poverty, illness, and 48 of resourcespreventing the flow of scientific information. Lifesaving knowledge we take for granted in the modern world is often 49 in underdeveloped regions.While studying at Harvard, I saw 50 scientific knowledge can help others in simple, yet profound ways. The bird flu in the 2000s looked to my village like a spell cast by devils. When I realized that simple hygiene (卫生) practices like 51 different animal species could contain the spread of the disease, and that I could help make this knowledge available to my village, that was my first "Aha" moment as a budding scientist.Harvard dares us to dream big, to aspire (立志) to change the world. Here on this Commencement Day, we are 52 thinking of grand destinations and big adventures that await us. As for me, I am also thinking of the farmers in my village. My experience here 53 me how important it's for researchers to communicate our knowledge to those 54 . Because by using the science we already have, we can probably bring my village and thousands like it into the world you and I take 55 every day. And that's an impact every one of us can make!36. A. medicine B. help C. advice D. decision37. A. in water B. on fire C. in trouble D. on strike38. A. leg B. chest C. hand D. face39. A. preserved B. forbade C. cancelled D. prevented40. A. before B. until C. when D. while41. A. beside B. behind C. after D. within42. A. accurately B. simply C. constantly D. continuously43. A. cool B. right C. absurd D. puzzling44.

Companies such as Canfor and West Fraser Timber Co., the second and third largest lumber (木材) producers in the world, are headquartered in Vancouver. Vancouver is also a major centre for the mining industry.International TradeInternational trade is a key part for Vancouver's economy. The city has Canada's largest port and is one of North America's major gateways for Pan-Pacific trade. The Port of Vancouver ranks first in North America in total foreign exports and second on the West Coast in total goods volume.Banking and FinanceThe headquarters for HSBC Canada is located in the Financial District in downtown. Canada's third largest commercial entity (实体), Jim Pattison Group is also based in Vancouver.International RelationV ancouver is a major centre for diplomacy (外交) and foreign relations. Most countries of the world have consulate (领事馆) or general offices in the Central Business District. In fact, many major diplomatic conferences are hosted by the city - including the world famous G7 summit with President Clinton, APEC, and the World Trade Organization. Greenpeace has its world headquarters in the city. Therefore, Vancouver was among the first NorthAmerican cities to declare itself a Nuclear Weapons Free Zone.TourismTourism is a leading industry to Vancouver. The Whistler-Blackcomb Resort is among the most popular skiing resorts in North America, and was the site of the downhill events of the 2010 Winter Olympics. Vancouver's beaches, parks, waterfronts, and mountain backdrops and its multi-cultural character attract more and more tourists.FilmsVancouver was also called "Hollywood North", for hosting the production of about ten percent of Hollywood's movies. Many U.S. television and film series are shot exclusively in Vancouver. This has partly been because of the favourable Canadian dollar exchange rate.56. Which of the following description about Vancouver is NOT true according to the passage?A. The Port of Vancouver ranks first in North America in total foreign exports.B. Vancouver is a film production centre and called "Hollywood North".C. International forestry conferences and events were held in Vancouver.D. Vancouver is a leading centre for the global agriculture and industry.57. Which of the following organizations or events is not related to Vancouver?A. Jim Pattison GroupB. WHOC. GreenpeaceD. The 2010 Winter Olympics58. The passage is probably taken from .A. a business magazineB. a geography bookC. a financial newspaperD. an entertainment bookBIf you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses.Here is an example, which I heard at a nurses' convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and. is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps (重踏) over to a table by himself. "Who is that?" the new arrival asked St. Peter. "Oh, that's God." came the reply, "but sometimes he thinks he's a doctor."If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it'll be appropriate for you to make a passing remark about the uneatable canteen food or the chairman's notorious (臭名昭著的) bad taste in ties. With other audiences you mustn't attempt to cut in with humor as they will resent an outsider making remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats (替身) like the Post Office or the telephone' system.If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff (即兴) remarks which you can deliver in a relaxed and unforced manner. Often it's the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don't succeed, give up" or a play on words or a situation. Search for exaggeration and understatements (轻描淡写). Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.59. To make your humor work, you should .A. take advantage of different kinds of audienceB. make fun of the disorganized peopleC. address different problems to different peopleD. show sympathy for your listeners60. In the eyes of nurses, the joke about doctors implies that they are .A. impolite to new arrivalsB. entitled (有资格) to some privilegesC. very conscious of their godlike roleD. very busy even during lunch hours61. It can be inferred from the text that public services .A. have benefited many peopleB. are the focus of public attentionC. are an inappropriate subject for humorD. have often been the laughing stock62. The best title for the text may be .A. Effective ways to use humorB. An appropriate topic matters in humorC. How to add humor to speechD. Casualness makes for natural humorCWhy do some people flush when they drink alcohol? This effect is a common reaction to alcohol among EastAsians. It affects about 36 percent of Japanese, Chinese and Koreans.For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation (感觉), increased heart rate, shortness of breath and headaches.The cause is a genetic difference that they are born with called an ALDH2 deficiency (缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus (食道) from drinking alcohol.The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers have found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world's population.Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.63. The underlined word "flush" in Paragraph 1 probably means" ".A. walk unsteadilyB. turn red in the faceC. appear unpleasantD. talk more than usual64. The second paragraph is mainly about .A. the cause of the effects of alcoholB. Asians and alcoholC. the advantages of drinking alcoholD. unpleasant effects caused by alcohol65. Esophageal cancer is considered one of the deadliest cancers in that .A. it can't be treated at allB. it is not easy to be discovered earlyC. it is hard to cure once it has developedD. people are addicted to alcohol66.We can infer from the passage that .A. only some East Asians have the ALDH2 deficiencyB. about 36 percent of Japanese, Chinese and Koreans are heavy drinkersC. unpleasant effects occur only when people with this deficiency drink a lotD. the ALDH2 deficiency may be passed on from generation to generationD"I moved him," the old man said. "I moved him then." He felt faint again now but he held on the great fish all the strength that he could. 1 moved him, he thought. Maybe this time I can get him over. Pull, hands, he thought. Hold up, legs. Last for me, head. Last for me. You never went. This time I'll pull him over.But when he put all of his effort on, starting it well out before the fish came alongside and pulling with all his strength, the fish pulled part way over and then righted himself and swam away."Fish," the old man said. "Fish, you are going to have to die anyway. Do you have to kill me too?"That way nothing is accomplished, he thought. His mouth was too dry to speak but he could not reach for the water now. I must get him alongside this time, he thought. I am not good for many more turns. Yes, you are, he told himself. You're good for ever.On the next turn, he nearly had him. But again the fish righted himself and swam slowly away.You are killing me, fish, the old man thought. But you have a right to. Never have I seen a greater, or more beautiful, or a calmer or more noble thing than you, brother. Come on and kill me. I do not care who kills who.Now you are getting confused in the head, he thought. You must keep your head clear. Keep your head clear and know how to suffer like a man. Or a fish, he thought."Clear up, head," he said in a voice he could hardly hear. "Clear up."Twice more it was the same on the turns.I do not know, the old man thought. He had been on the point of feeling himself go each time. I do not know. But I will try it once more.He tried it once more and he felt himself going when he turned the fish. The fish righted himself and swam off again slowly with the great tail heaving in the air.I'll try it again, the old man promised, although his hands were mushy now and he could only see well in flashes.He tried it again and it was the same. So he thought, and he felt himself going before he started; I will try it once again.The old man dropped the line and put his foot on it and lifted the harpoon (鱼叉) as high as he could and drove it down with all his strength, and more strength he had just summoned (召集), into the fish's side just behind the great chest fin that rose high in the air to the altitude of the man's chest. He felt the iron go in and he leaned on itand drove it further and then pushed all his weight after it.Then the fish came alive, with his death in him, and rose high out of the water showing all his great length and width and all his power and his beauty. He seemed to hang in the air above the old man in the skiff. Then he fell into the water with a crash that sent spray (喷) over the old man and over all of the skiff.67. Why did the old man keep talking to himself while fighting against the fish?A. To rescue himself from great pressure.B. To remind himself of the hidden danger.C. To prevent himself from feeling tired.D. To give himself constant encouragement.68. Which of the following statements is true about the fisherman?A. The fisherman seemed to be playing a cat-and-mouse game with the fish.B. The fisherman showed respect for his rival in this fierce battle.C. The fisherman has been fighting with the fish for long, which made him anxious.D. The fisherman, experienced as he was in fishing, nearly got killed on several occasions.69. What can be inferred from the sentence "Fish, you are going to have to die anyway"(Para. 3) ?A. Quite a few fishermen were chasing and hunting the fish.B. The fish had been seriously injured and couldn't live long.C. The old man had much confidence in catching the fish.D. As a matter of fact, the fish was too old to live any longer.70. Which of the following words best describes the old man?A. Ambitious.B. Aggressive.C. Strong-willed.D. Sympathetic.。

Twain's racial tone was not perfect. One is left uneasy,for example,by the lengthy passage in his autobiography(自传 )about how much he loved what were called “nigger shows” in his youth mostly with white men performing in lackface and his delight in getting his mother to laugh at them. Yet there is no reason to think Twain saw the shows as representing reality. His frequent attacks on slavery and prejudice suggest his keen awareness that they did not.

The bird flu in the2000s looked to my village like a spell cast by devils.When I realized that simple hygiene(卫生) practices like51different animal species could contain the spread of the disease,and that I could help make this to my village,that was my first"Aha"moment as a budding scientist.Harvard dares us to dream big,to aspire(立志)to change the world.Here on this Commencement Day,we are 52thinking of grand destinations and big adventures that await us.As for me,I am also thinking of the farmers in my village.My experience here53me how important it's for researchers to communicate our knowledge to those54.Because by using the science we already have,we can probably bring my village and thousands like it into the world you and I take55every day.And that's an impact every one of us can make!36.A.medicine B.help C.advice D.decision37.A.in water B.on fire C.in trouble D.on strike38.A.leg B.chest C.hand D.face39.A.preserved B.forbade C.cancelled D.prevented40.A.before B.until C.when D.while41.A.beside B.behind C.after D.within42.A.accurately B.simply C.constantly D.continuously43.A.cool B.right C.absurd D.puzzling44.A.powerful B.stressful C.painful D.regretful45.A.accept B.receive C.adopt D.adapt46.A.distribution B.donation C.allocation D.distraction47.A.involved B.absorbed C.successful D.careful48.A.separation B.plenty C.absence ck49.A.unavailable B.unwanted C.unexpected D.Unnecessary50.A.when B.where C.how D.why51.A.dividing B.separating C.splitting D.breaking52.A.skilfully B.probably C.preferably D.relativelyrms B.recalls C.reminds D.refers54.A.in danger B.in need C.in order D.in shape55.A.for granted B.for example C.into consideration D.into practice第三部分阅读理解(共15小题:每小题2分,满分30分)AVancouverNatural ResourcesAs a major centre for the global forestry industry,Vancouver is host to many international forestry conferences and events,and the natural home of the massive BC forestry panies such as Canfor and West Fraser Timber Co.,the second and third largest lumber(木材)producers in the world,are headquartered in Vancouver.

GroupB.WHOC.GreenpeaceD.The2010Winter Olympics58.The passage is probably taken from.A.a business magazineB.a geography bookC.a financial newspaperD.an entertainment bookBIf you intend using humor in your talk to make people smile,you must know how to identify shared experiences and problems.Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view.Depending on whom you are addressing,the problems will be different.If you are talking to a group of managers,you may refer to the disorganized methods of their secretaries;alternatively if you are addressing secretaries,you may want to comment on their disorganized bosses.Here is an example,which I heard at a nurses'convention,of a story which works well because the audience all shared the same view of doctors.A man arrives in heaven and.is being shown around by St.Peter.He sees wonderful accommodations,beautiful gardens,sunny weather,and so on.Everyone is very peaceful,polite and friendly until,waiting in a line for lunch,the new arrival is suddenly pushed aside by a man in a white coat,who rushes to the head of the line,grabs his food and stomps(重踏)over to a table by himself."Who is that?"the new arrival asked St.Peter."Oh,that's God."came the reply,"but sometimes he thinks he's a doctor."If you are part of the group which you are addressing,you will be in a position to know the experiences and problems which are common to all of you and it'll be appropriate for you to make a passing remark about the uneatable canteen food or the chairman's notorious(臭名昭著的)bad taste in ties.With other audiences you mustn't attempt to cut in with humor as they will resent an outsider making remarks about their canteen or their chairman.You will be on safer ground if you stick to scapegoats(替身)like the Post Office or the telephone' system.If you feel awkward being humorous,you must practice so that it becomes more natural.Include a few casual and apparently off-the-cuff(即兴)remarks which you can deliver in a relaxed and unforced manner.Often it's the delivery which causes the audience to smile,so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.Look for the humor.It often comes from the unexpected.A twist on a familiar quote"If at first you don't succeed,give up"or a play on words or a situation.Search for exaggeration and understatements(轻描淡写).Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.59.To make your humor work,you should.A.take advantage of different kinds of audienceB.make fun of the disorganized peopleC.address different problems to different peopleD.show sympathy for your listeners60.In the eyes of nurses,the joke about doctors implies that they are.A.impolite to new arrivalsB.entitled(有资格)to some privilegesC.very conscious of their godlike roleD.very busy even during lunch hours61.It can be inferred from the text that public services.A.have benefited many peopleB.are the focus of public attentionC.are an inappropriate subject for humorD.have often been the laughing stock62.The best title for the text may be.A.Effective ways to use humorB.An appropriate topic matters in humorC.How to add humor to speechD.Casualness makes for natural humorCWhy do some people flush when they drink alcohol?This effect is a common reaction to alcohol among EastAsians.It affects about36percent of Japanese,Chinese and Koreans.For many,even a small amount of alcohol can cause unpleasant effects.Most commonly,their face,neck and sometimes their whole body turn red.People might also feel uncomfortable and sick to their stomach.They might experience a burning sensation(感觉),increased heart rate,shortness of breath and headaches.The cause is a genetic difference that they are born with called an ALDH2deficiency(缺乏).It prevents their bodies from treating alcohol the way other people do.But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus(食道)from drinking alcohol.The more alcohol people with this deficiency drink,the greater their risk is.In Japan and South Korea,for example,many people have the deficiency but still drink heavily.Researchers have found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.Esophageal cancer is one of the deadliest cancers.It can be treated when found early,but once it grows the chances of survival drop sharply.The researchers estimate that at least five hundred forty million people have the deficiency,about eight percent of the world's population.Philip Brooks is a researcher at the National Institute in the United States.He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer.He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol.Those with a history of it should be advised to limit their alcohol use.They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.63.The underlined word"flush"in Paragraph1probably means"".A.walk unsteadilyB.turn red in the faceC.appear unpleasantD.talk more than usual64.The second paragraph is mainly about.A.the cause of the effects of alcoholns and alcoholC.the advantages of drinking alcoholD.unpleasant effects caused by alcohol65.Esophageal cancer is considered one of the deadliest cancers in that.A.it can't be treated at allB.it is not easy to be discovered earlyC.it is hard to cure once it has developedD.people are addicted to alcohol66.We can infer from the passage that.A.only some East Asians have the ALDH2deficiencyB.about36percent of Japanese,Chinese and Koreans are heavy drinkersC.unpleasant effects occur only when people with this deficiency drink a lotD.the ALDH2deficiency may be passed on from generation to generationD"I moved him,"the old man said."I moved him then."He felt faint again now but he held on the great fish all the strength that he could.1moved him,he thought.Maybe this time I can get him over.Pull,hands,he thought. Hold up,st for me,st for me.You never went.This time I'll pull him over.But when he put all of his effort on,starting it well out before the fish came alongside and pulling with all his strength,the fish pulled part way over and then righted himself and swam away."Fish,"the old man said."Fish,you are going to have to die anyway.Do you have to kill me too?"That way nothing is accomplished,he thought.His mouth was too dry to speak but he could not reach for the water now.I must get him alongside this time,he thought.I am not good for many more turns.Yes,you are,he told himself.You're good for ever.On the next turn,he nearly had him.But again the fish righted himself and swam slowly away.You are killing me,fish,the old man thought.But you have a right to.Never have I seen a greater,or more beautiful,or a calmer or more noble thing than you,e on and kill me.I do not care who kills who.Now you are getting confused in the head,he thought.You must keep your head clear.Keep your head clear and know how to suffer like a man.Or a fish,he thought."Clear up,head,"he said in a voice he could hardly hear."Clear up."Twice more it was the same on the turns.I do not know,the old man thought.He had been on the point of feeling himself go each time.I do not know. But I will try it once more.He tried it once more and he felt himself going when he turned the fish.The fish righted himself and swam off again slowly with the great tail heaving in the air.I'll try it again,the old man promised,although his hands were mushy now and he could only see well in flashes.He tried it again and it was the same.So he thought,and he felt himself going before he started;I will try it once again.The old man dropped the line and put his foot on it and lifted the harpoon(鱼叉)as high as he could and drove it down with all his strength,and more strength he had just summoned(召集),into the fish's side just behind the great chest fin that rose high in the air to the altitude of the man's chest.He felt the iron go in and he leaned on itand drove it further and then pushed all his weight after it.Then the fish came alive,with his death in him,and rose high out of the water showing all his great length and width and all his power and his beauty.He seemed to hang in the air above the old man in the skiff.Then he fell into the water with a crash that sent spray(喷)over the old man and over all of the skiff.67.Why did the old man keep talking to himself while fighting against the fish?A.To rescue himself from great pressure.B.To remind himself of the hidden danger.C.To prevent himself from feeling tired.D.To give himself constant encouragement.68.Which of the following statements is true about the fisherman?A.The fisherman seemed to be playing a cat-and-mouse game with the fish.B.The fisherman showed respect for his rival in this fierce battle.C.The fisherman has been fighting with the fish for long,which made him anxious.D.The fisherman,experienced as he was in fishing,nearly got killed on several occasions.69.What can be inferred from the sentence"Fish,you are going to have to die anyway"(Para.3)?A.Quite a few fishermen were chasing and hunting the fish.B.The fish had been seriously injured and couldn't live long.C.The old man had much confidence in catching the fish.D.As a matter of fact,the fish was too old to live any longer.70.Which of the following words best describes the old man?A.Ambitious.B.Aggressive.C.Strong-willed.D.Sympathetic.。
