Bill gates: Unleashing your creativity
I’ve always been an optimists and I suppose that is rooted in my belief that the power of creativity and intelligence can make the world a better place.
For as long as I can remember, I’ve loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a chunky old teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.
When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of “a computer on every desk and in every home,” which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have.
And after 30 years, I’m still as inspired by computers as I was back in seventh grade.
I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness to help us solve problems that even the smartest people couldn’t solve on their own.
Computers have transformed how we learn, giving kids everywhere a window into all of the world’s knowledge. They’re helping us build communities around the things we care about and to stay close to the people who are important to us, no matter where they are.
Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it “tap-dancing to work”. My job at Microsoft is as challenging as ever, but what makes me “tap-dancing to work” is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetime’s worth of photos, and they say, “I didn’t know you could do that with a PC!”
But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world. There are still far too many people in the world whose most basic needs go unmet. Every year, for example, millions of people die from diseases that are easy to prevent or treat in the developed world.
I believe that my own good fortune brings with it a responsibility to give back to the world. My wife, Melinda, and I have committed to improving health and education in a way that can help as many people as possible.
As a father, I believe that the death of a child in Africa is no less poignant or tragic than the death pf a child anywhere else, and that it doesn’t take much to make an immense difference in these children’s lives.
I’m still very much an optimist, and I believe that progress on even the world’s toughest problems is possible and it’s happening every day. We’re seeing new drugs for deadly diseases, new diagnostic tools, and new attention paid to the health problems in the developing world.
I’m excited by the possibilities I see for medicine, for education and, of course, for technology. And I believe that through our natural inventiveness, creativity and willingness to solve tough problems, we’re going to make some amazing in all these area in my life. (563 words)

More Than 8 Hours Sleep Too Much of a Good Thing
Although the dangers of too little sleep are widely known，new research suggests that people who sleep too much may also suffer the consequences.
Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep，as well as a number of other sleep problems，than people who sleep 8 hours a night.People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers.
These findings, which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night’s rest may not need to set aside。more than 8 hours a night.He added that“it might be a good idea'’for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this.
Previous studies have shown the potential dangers of chronic shortages of sleep一for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
For the current report，Kripke reviewed the responses of 1，004 adults to sleep questionnaires，in which participants indicated how much they slept during the Week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night，arising early in the morning and being unable to fall back to sleep，and having fatigue interfere with day-to-day functioning.
KriDke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed.As evidence，he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake.”he said.
1. Paragraph 2 ___.
2. Paragraph 4___.
3. Paragraph 5___.
4. Paragraph 6___.
A. Keprike’s research tool
B. Dangers of Habitual shortages of sleep
C. Criticism on Kripke’s report
D. A way of overcoming insomnia
E. Sleep problems of long and short sleepers
F. Classification of sleep problems
标准答案：E,B,A,D
解 析：1. E： Investigators ...found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling, than...该句回应了文章的主题—睡眠时间太长不是好事;对应被选项发现只有E和F与这个内容有关系，但段落最后一句中又提到了睡眠不足的人的问题，因此判断E是答案(睡眠长和睡眠短的人所面临的睡眠问题)。
2。B.分析：段落的结构-- Previous studies have shown the potential dangers of chronic shortages of sleep一for instance..表明了该段的中心是讲述“长期睡眠不足的潜在危险”
3. A. 分析：对于该段落答案的选择具有一定的迷惑性，A和F容易相互成为干扰项，但由于段落中提到的“睡眠问题”是属于问卷上要回答的内容，是和Keprike的直接研究有关，所以判断A是答案。同时猜测F可能是干扰项
4. D： 段落中出现的Kripke found， Kripke noted和he added表明“Kripke的观点和态度应该是该段的中心”，对比被选项排除C(段落中没有出现批评的话语)和F(段落中没有具体提到睡眠问题的表现形式)，而段落最后第2句提到了克服失眠的方法—少花时间在床上，与D呼应。
19、 5.To get a good night’s rest，people may not need to ___.
6.Long sleepers are reported to be more likely to___.
7. One of the sleep problems is waking in the middle of the night，unable to___.
8. One survey showed that people who habitually ___each night have a higher risk of dying.
A fall asleep again
B become more energetic the following day
C sleep less than 7 hours
D confirm those serious consequences
E suffer sleep problems
F sleep more than 8 hours
标准答案：F,E,A,C
解 析：5.F.分析：根据搭配结构need to do sth.判断所有选项都在语法上合适。借助搭配句意：“为了获得晚上好的休息，人们没有必要。。”判断F(睡眠超过8小时)。
6.E.分析：借助搭配句意：“睡眠时间长的人根据报道更有可能。。”，并结合文章主题—睡眠时间长不是好事情，判断E合适。也可借助文章中的相关内容(利用题干中的Long sleepers和more likely 作为答案线索)：Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.
7.A. 分析：借助搭配句意：“其中的一个睡眠问题是在午夜醒来，不能。。”，直接判断A(再次入睡)合适。
8.C.分析：借助搭配句意：“一项调查显示那些习惯性每晚...的人有更高的死亡风险。”
下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案涂在答题卡相应的位置上。
第1篇
Eating potatoes gives your immune system a boost
Eating potatoes is not only good for bowel health, but also for the whole immune system, especially when they come in the form of a potato salad or eaten cold. In a study on an animal model, researchers in Spain found that pigs fed large quantities of raw potato starch (RPS)1 not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease, generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body.2 The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.
In what was the longest study of its kind, pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. “The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch”, said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,3 Spain.
Humans do not eat raw potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch - starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).4
Immunology expert Lena Ohman’s team previously found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth trying in IBS patients. Ohman is currently at the Department of Internal Medicine, Goteborg University, Sweden.5 The study is published in the journal Chemistry and Industry, the magazine of the SCI.6
1.What a form of potato is the most nutrient to the human body?
A) Potato soup.
B) Potato cake.
C) Potato salad.
D) Hot boiled potato.
2. What does the reduction in leucocyte levels in the body mean?
A) It may mean the reduced levels of inflammation.
B) It may mean somewhere in the body is inflamed.
C) It means that the body is challenged.
D) It means that the body cannot produce leucocytes any more.
3. For what a purpose did the researchers use raw potato starch in their experiment?
A)They wanted to observe how the leucocyte levels reduced in the experimental pigs?
B)They wanted to simulate the effects of a diet high in resistant starch.
C)They wanted to see how much potato an experimental pig ate every day.
D)They wanted to see how much body weight each experimental pig gained in the end.
4. All of the following foods are rich in resistant starch EXCEPT __________.
A) Pasta
B) Grains
C) Legumes
D) Vegetables
5.What a kind of starch is resistant starch after all?
A)It may cause irritable bowel syndrome.
B) It may bring about at least partially inflammatory disorder.
C) It may raise leucocyte and lymphocyte levels in the body.
D) It cannot be digested in the small intestine and ferments in the large intestine.
标准答案：C,A,B,D,D
解 析：1.C. 细节题。 利用问题句中以最高级的形式出现的修饰结构及细节信息结构(the most nutrient, human body)及被选项中的细节信息词(A: soup; B: cake; C: salad; D: boiled potato)共同作为答案线索， 在文章中查找答案相关句：

答案相关句(第4段倒数第2句)已经解释了耐久淀粉的特点：“不能在小肠中消化，而是分流到大肠，在大肠中发酵”。
第2篇
Find Yourself Packing It On? Blame Friends
Obesity can spread from person to person, much like a virus, researchers are reporting today. When one person gains weight, close friends tend to gain weight, too.
Their study, published in The New England Journal of Medicine, involved a detailed analysis of a large social network of 12,067 people who had been closely followed for 32 years, from 1971 to 2003.
The investigators knew who was friends with whom as well as who was a spouse or sibling or neighbor, and they knew how much each person weighed at various times over three decades. That let them reconstruct what happened over the years as individuals became obese. Did their friends also become obese? Did family members? or neighbors?
The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a persons chances or becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight，however, and family members had less influence than friends.
It did not even matter if the friend was hundreds of miles away, the influence remained. And the greatest influence of all was between close mutual friends. There, if one became obese, the other had a 171 percent increased chance of becoming obese, too.
The same effect seemed to occur for weight loss, the investigators say. But since most people were gaining, not losing, over the 32 years, the result was, on average, that people grew fatter.
Dr. Nicholas A. Christakis, a physician and professor of medical sociology at Harvard Medical School and a principal investigator in the new study, said one explanation was that friends affected each others’ perception of fatness. When a close friend becomes obese, obesity may not look so bad.
“You change your idea of what is an acceptable body type by looking at the people around you,” Dr. Christakis said.
The investigators say their findings can help explain why Americans have become fatter in recent years each person who became obese was likely to drag along some friends!
Their analysis was unique, Dr. Christakis said, because it moved beyond a simple analysis of one person and his or her social contacts and instead examined an entire social network at once, looking at how a person's friend's friends, or influence on a person's weight or a spouse's sibling's friends, could have an influence on a person’s weight.
The effects, he said, “highlight the importance of contagion, that spreads through the network.”
Of course, the investigators say, social networks are not the only factors that affect body weight. There is a strong genetic component at work, too.
Science has shown that individuals have genetically determined ranges of weights, spanning perhaps 30 or so pounds for each person. But that leaves a large role for the environment in determining whether a person’s weight is near the top of his or her range or near the bottom. As people have gotten fatter, it appears that many are edging toward the top of their ranges. The question has been why.
If the new research is correct, it may say that something in the environment seeded what some call an obesity epidemic, making a few people gain weight. Then social networks let the obesity spread rapidly.
1. Who had the greatest influence on people who became obese?
A. their friends
B. their neighbors
C. their family members
D. their colleagues
2. Which of the following statement about a friend's influence is false according to the report?
A. Friends had more influence than family members on people who became obese.
B. Even if the friend lives far away, the influence still remained
C. People were not likely to lose weight when they have skinny friends.
D. The greatest influence of all was between close mutual friends.
3. According to Dr. Nicholas A. Christakis, what is the explanation for friends being the greatest influence?
A. Friends usually spend a lot of time together.
B. Friends share similar eating habits.
C. Friends are more important than family members.
D. Friends affected each others’ feelings of fatness
4. Which factor of becoming obese is not mentioned in this report?
A. social contact
B. genetic information
C. life style
D. environmental influence
5. In what way is obesity contagious and epidemic?
A. social networks let the obesity spread rapidly
B. individuals have genetically determined rages of weights.
C. Obesity can easily spread from one to another within any physical contact
D. Obesity can spread rapidly and extensively by infection and affecting many individuals in an area or a population at the same time.
标准答案：A,C,D,C,A
解 析：1.A. 该题可根据文章主题(文章标题内容)“如果你发现自己变胖了， 你应该责怪你的朋友们”直接判断答案。 也可以依据文章中的相关内容判定答案：利用备选项中的细节信息词(A：friends; B: neighbors; C: family members; D: colleagues)共同作为答案线索， 在文章中查找答案相关句：
(第一题答案相关句)(第4段)The answer(答案), the researchers(研究者) report(报告), was that people were most likely to (很可能...)become obese(肥胖的) when a friend (朋友)became obese. That increased(增加) a person’s chances of (...的机会/可能性)becoming obese by (了)57 percent(百分之). There was no effect(influence的近义词)(影响， 实现) when a neighbor gained or lost weight(增肥或减肥)，however(然而), and family members had less (较少的， 不太，不(如))influence(影响) than friends.
答案相关句(第四段)说“提到研究者发现，当周围朋友发福时，人最容易发胖.而邻居则不会对人产生影响，甚至家庭成员的影响也不如朋友大。而关于同事的内容，文章中并没有提到。
2.C. 可以借助文章主题或接着解答上一题所获得的相关信息直接判断C错误。 也可以借助文章中的相关内容判断答案：
(第一题答案相关句)The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a persons chances or becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight，however, and family members had less influence than friends.
(第二题答案相关句)It did not even(甚至) matter(有关系。 事情， 物质)if (是否， 如果)the friend was hundreds of miles away(在远处， 到远处), the influence remained(继续). (与选项B内容一致)And the greatest influence of all was between close (亲密的)mutual(相互的) friends(与选项D内容一致). There, if one became obese, the other had a 171 percent increased chance of becoming obese, too.
A选项说的是“朋友产生的影响大于庭成员”，该选项内容与第一题答案相关句内容一致; B选项也是正确的， 因为第五段第一句话提到，即使朋友远在千里之外，这种影响仍然存在：第五段第二句特合D选项的愈思：那些关系亲密的朋友产生的影响最大。因此只有C不正确。
3.D. 利用问题句中的特征词(Nicholas A. Christakis)作为答案线索， 同时利用备选项B中的典型细节信息结构(eating habits)作为答案线索， 在文章中查找答案相关句
(第2题答案相关句)(第5段)It did not even matter if the friend was hundreds of miles away, the influence remained. And the greatest influence of all was between close mutual friends. There, if one became obese, the other had a 171 percent increased chance of becoming obese, too.
(第6段)The same effect seemed to occur for weight loss, the investigators say. But since most people were gaining, not losing, over the 32 years, the result was, on average, that people grew fatter.
(第7段)Dr. Nicholas A. Christakis, a physician(医生) and(兼) professor (教授)of medical(医学的) sociology(社会学) at Harvard Medical School(哈佛医学院)and a principal(主要的， 校长， 负责人) investigator(调查人) in the new study(研究), said one explanation (问题句中的核心词)was that friends affected(影响) each others(彼此)’ perception(理解)(perception是feeling的近义词) of fatness(肥胖). When a close friend (亲密的朋友)becomes obese, obesity may not look so bad.
答案相关句(第七段第一句)涉及到了Dr. Nicholas A. Christakia对于这种现象的解释：朋友之间对于肥胖的感知是互相影响的。因此D是答案。

第2篇
Find Yourself Packing It On? Blame Friends
Obesity can spread from person to person, much like a virus, researchers are reporting today. When one person gains weight, close friends tend to gain weight, too.
Their study, published in The New England Journal of Medicine, involved a detailed analysis of a large social network of 12,067 people who had been closely followed for 32 years, from 1971 to 2003.
The investigators knew who was friends with whom as well as who was a spouse or sibling or neighbor, and they knew how much each person weighed at various times over three decades. That let them reconstruct what happened over the years as individuals became obese. Did their friends also become obese? Did family members? or neighbors?
The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a persons chances or becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight，however, and family members had less influence than friends.
It did not even matter if the friend was hundreds of miles away, the influence remained. And the greatest influence of all was between close mutual friends. There, if one became obese, the other had a 171 percent increased chance of becoming obese, too.
The same effect seemed to occur for weight loss, the investigators say. But since most people were gaining, not losing, over the 32 years, the result was, on average, that people grew fatter.
Dr. Nicholas A. Christakis, a physician and professor of medical sociology at Harvard Medical School and a principal investigator in the new study, said one explanation was that friends affected each others’ perception of fatness. When a close friend becomes obese, obesity may not look so bad.
“You change your idea of what is an acceptable body type by looking at the people around you,” Dr. Christakis said.
The investigators say their findings can help explain why Americans have become fatter in recent years each person who became obese was likely to drag along some friends!
Their analysis was unique, Dr. Christakis said, because it moved beyond a simple analysis of one person and his or her social contacts and instead examined an entire social network at once, looking at how a person's friend's friends, or influence on a person's weight or a spouse's sibling's friends, could have an influence on a person’s weight.
The effects, he said, “highlight the importance of contagion, that spreads through the network.”
Of course, the investigators say, social networks are not the only factors that affect body weight. There is a strong genetic component at work, too.
Science has shown that individuals have genetically determined ranges of weights, spanning perhaps 30 or so pounds for each person. But that leaves a large role for the environment in determining whether a person’s weight is near the top of his or her range or near the bottom. As people have gotten fatter, it appears that many are edging toward the top of their ranges. The question has been why.
If the new research is correct, it may say that something in the environment seeded what some call an obesity epidemic, making a few people gain weight. Then social networks let the obesity spread rapidly.
1. Who had the greatest influence on people who became obese?
A. their friends
B. their neighbors
C. their family members
D. their colleagues
2. Which of the following statement about a friend's influence is false according to the report?

D. The greatest influence of all was between close mutual friends.
3. According to Dr. Nicholas A. Christakis, what is the explanation for friends being the greatest influence?
A. Friends usually spend a lot of time together.
B. Friends share similar eating habits.
C. Friends are more important than family members.
D. Friends affected each others’ feelings of fatness
4. Which factor of becoming obese is not mentioned in this report?
A. social contact
B. genetic information
C. life style
D. environmental influence
5. In what way is obesity contagious and epidemic?
A. social networks let the obesity spread rapidly
B. individuals have genetically determined rages of weights.
C. Obesity can easily spread from one to another within any physical contact
D. Obesity can spread rapidly and extensively by infection and affecting many individuals in an area or a population at the same time.
标准答案：A,C,D,C,A
解 析：1.A. 该题可根据文章主题(文章标题内容)“如果你发现自己变胖了， 你应该责怪你的朋友们”直接判断答案。 也可以依据文章中的相关内容判定答案：利用备选项中的细节信息词(A：friends; B: neighbors; C: family members; D: colleagues)共同作为答案线索， 在文章中查找答案相关句：
(第一题答案相关句)(第4段)The answer(答案), the researchers(研究者) report(报告), was that people were most likely to (很可能...)become obese(肥胖的) when a friend (朋友)became obese. That increased(增加) a person’s chances of (...的机会/可能性)becoming obese by (了)57 percent(百分之). There was no effect(influence的近义词)(影响， 实现) when a neighbor gained or lost weight(增肥或减肥)，however(然而), and family members had less (较少的， 不太，不(如))influence(影响) than friends.
答案相关句(第四段)说“提到研究者发现，当周围朋友发福时，人最容易发胖.而邻居则不会对人产生影响，甚至家庭成员的影响也不如朋友大。而关于同事的内容，文章中并没有提到。
2.C. 可以借助文章主题或接着解答上一题所获得的相关信息直接判断C错误。 也可以借助文章中的相关内容判断答案：
(第一题答案相关句)The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a persons chances or becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight，however, and family members had less influence than friends.

The Arctic Ice is Thawing
Father Christmas may have to move his “workshop” from the North Pole because global warming is thawing the ice beneath his feet and his reindeers' feet as well. His “workshop” is in dire straits. The “platform” for the “workshop” is melting, said Stefan Norris of the World Wildlife Fund environmental group's Arctic Program.
An eight-nation report by 250 scientists published recently predicted the Arctic Ocean could be ice-free in summer by 2100 because of a build-up of heat-trapping gases in the atmosphere, mainly from burning fossil fuels in cars or factories. The North Pole is getting more and more inhabitable to Father Christmas. ___1___. Young people learn that Father Christmas' “workshop” produces millions of gifts delivered by him on a flying, reindeer-drawn sleigh. Hollywood movies like "The Polar Express" tried to make viewers believe that Father Christmas lives at the North Pole. ___2___.
The "Fortress of Solitude" is near the North Pole that could be under threat in a warmer world. Alan Boldt, spokesman of the Danish Ministry of Science, suggested ways to rescue Father Christmas. ___3___. Another alternative, he argued, would be building some electrical facilities to ensure the ice stays on the North Pole for him. "This should be a subject for the United Nations," he said. “Danmark could build windmills to provide Father Christmas with power." Denmark says Father Christmas’s real home is Greenland, which will help, Denmark thinks, to strengthen its position in claiming the sovereignty over the Pole. ___4___.
"Doesn't he already speak Danish?" Boldt said frostily when asked if Father Christmas would be forced to learn Danish if Denmark won international recognition of its claim to the Pole. Last month's Arctic report said the region is warming twice as fast as the rest of the globe, partly because dark ground or water, once uncovered, soaks up more heat than ice or snow. Finland has been most favored by Father Christmas and it has about 500,000 tourists a year to visit its Christmas center in Rovaniemi in Lapland6. ___5___.
A.However, Nordic nations all reject it by claiming that their countries are his home.
B.Therefore the North Pole is the most attractive place in the world.
C.If Denmark’s claim were accepted internationally, it would have the legal right to search for oil and gas at the North Pole.
D.One of them would be building a giant floating ice rink for the workshop if the Pole thaws.
E.Maybe Father Christmas has already moved to Rovaniemi.
F.He may have to move from the North Pole within our children's lifetimes.
标准答案：F,A,D,C,E
解 析：1. F “空1” 前面两个句子讲的是，受全球气候变暖的影响，北极的冰正在融化，估计到2100年夏天北极将成为无冰的世界。北极越来越不适合圣诞老人居住了。于是，读者或许会猜想，在这种情况下，圣诞老人该怎么办呢?选项 F 说， “He may have to move from the North Pole within our children's lifetimes”，其意思与上文配合得天衣无缝，北极住不下去了，只能移居他处。因此 F 是答案。
2. A “空2”前面一句说，好莱坞电影 “极地快车”想让观众相信圣诞老人的故乡在北极。下面该填什么呢?选项A说， “However, Nordic nations all reject it by claiming that their countries are his home”，北欧国家不同意这种说法，都声称自己的国家才是圣诞老人的故乡。意思和上文配得上，但意思正好相反。 所以，“空2”句子的句首用 however 与前一句接起来。A 是答案。
3. D “空3”前面一句说，丹麦科学部发言人提出拯救圣诞老人的几个办法。 “空3”的内容应该涉及具体的拯救办法。选项 D 符合这个要求。D 说其中一个办法是：如果北极的冰融化，就人工造个浮冰场地，上面可以承载圣诞老人的工场。 从上下文意思的连接上，从 one of them (指代前一句的 ways) 的用词上，都可以确定，D 是答案。
4. C 选项 C 的句子一开始就用 “Denmark’s claim”重复“空4”前面一句的 “claiming (to the sovereignty over the Pole)”，从词汇重复上，我们可以判断，填入“空4”的句子应该是 选项 C 的句子。我们再从意思上分析一下。丹麦认为，说圣诞老人的故乡是格陵兰有助于加强丹麦声称自己拥有北极的主权的地位。选项 C 说，如果丹麦的这一要求得到国际社会认可的话，它就拥有合法的权利去勘测北极的石油和天然气。上下文意思是连贯的，所以 C 是答案。
5. E “空5”前面一句说，“ Finland has been most favored by Father Christmas and it has about 500,000 tourists a year to visit its Christmas center in Rovaniemi in Lapland”。当看到 选项 E 中重复出现 Rovaniemi，就知道 “空5”的位置上应该是选项 E 的句子。圣诞老人如此眷顾 Rovaniemi，每年约有50万游客来参观 Rovaniemi 的圣诞中心。E 的句子说 “Maybe Father Christmas has already moved to Rovaniemi (说不定圣诞老人已经移居罗瓦涅米了) ”，是对前一句 “眷顾”的颇有风趣的总结，也是对与“空1”的句子 “He may have to move from the North Pole within our children's lifetimes” 遥相呼应。选项 E 是本题的答案。
阅读下面的短文，文中有15处空白，每处空白给出了4个选项，请根据短文的内容从4个选项中选择1个最佳答案，并涂在答题卡相应的位置上。
The placebo effect
Placebo is a Latin word. It means “I shall please”. And sometimes it just might. When scientists want to test a new drug, they usually divide a large number of people __1__ two groups. One group takes the medicine, the other takes a substance __2__ as a placebo. It may contain nothing more than sugar. The people do not know which pill they are taking, the active one or the inactive one. In this kind of experiment, the medicine must perform __3__ than the placebo to prove it is effective.
Yet, people who take a placebo, sometimes experience improvements in their health. This is known as “the placebo effect”—the effect of something __4__ is not supposed to have any effect.
Some doctors even use the placebo effect in their treatments. They might tell patients that a new drug will stop their pain. The patient does not know that the pills are __5__. The patient __6__ the pills and later tells the doctor that the pain is gone.
Now research in Sweden suggests that placebo treatments can also __7__ the emotional effects of unpleasant experiences. The effects in the brain were similar to those seem when placebos have been used to ease pain. The researchers say that in both cases expectations of improvement are a major __8__ on the effectiveness of placebos. The new study involved a group of people who looked at unpleasant pictures, __9__ images of dead bodies. Predrag Petrovic of the Karolinska Institute in Stockholm led the study. The findings appeared in the publication Neuron.
An influential study on placebos appeared in 1955. It said treatment with a placebo __10__ patients feel better 35% of the time. But in 2001, Danish researchers reported that they had examined more than 100 studies. They found __11__ evidence of healing as a result of placebos.
Some researchers think a good relationship between a doctor and patients can increase the effectiveness of real medicines. In any case, some medical researchers are against the use of __12__. They think it is __13__ to give some people inactive substances when testing new medicines. They say it would be better to __14__ new drugs with existing drugs. That way, a study would show __15__ the new drug is more effective.
1. A. in B. to C. into D. for
2. A. named B. called C. referred D. known
3. A. better B. worse C. more weakly D. more slowly
4. A. which B. that C. what D. whatever
5. A. active B. inactive C. effective D. helpful
标准答案：C,D,A,B,B
解 析：1. C. divide...into.../把...分成...
2.D.known as.../被称为...
3.A. 该句说“在这种试验中， 药物应该比安慰剂表现得更...，以证明自己是有效的”， 因此判断A(更好地)是答案。
4.B. 空格所在的从句为定语从句。现行词为不定代词(something, some, any, anything, all, little, etc)时引导定语从句的连接词只能为that.
5. B. 如果空格处的词义为“起作用的”， 则C和D也能出现在空格中， 因此这三个选项彼此排除掉， 答案只能为B(不起作用的)。
25、 6. A. gets B.buys C. takes D. brings
7. A. reduce B.increase C. raise D. enhance
8. A.information B. inspiration C.incident D. Influence
9. A. inasmuch as B.such as C. as if D. as for
10. A. got B. made C. caused D.rendered
标准答案：C,A,D,B,B
解 析：6. C。 根据上文内容和空格处的搭配(...the pills)判断C(服用)是答案。
7.A. C和D是近义词，这两个词不能与effect(影响)搭配使用， 因此排除C和D;空格所在的句子说“安慰剂效应也能...令人不愉快的情绪的影响” ， 借助上文内容 谈及安慰剂的积极作用， 因此空格处应该填reduce。
8.D.能与介词on搭配的只有influence和information: influence on.../对...的影响; information on.../关于...的消息， 根据句意判断D(影响)是答案。
9.B. 空格后出现的是名词性短语结构， 因此排除A和C(都是连词性的短语结构)。空格前面说“令人不愉快的图片”， 空格后是具体列举的内容， 因此B(例如)是答案。
10.B. 空格后出现不带to的不定式结构，因此空格处应该填made。
26、 11. A. few B. much C. many D. little
12. A. drugs B. cures C.placebos D. medicines
13. A. wrong B. right C. sensible D. reasonable
14. A. take B. produce C.combine D. compare
15. A. if B. how C. when D. where
标准答案：D,C,A,D,A
解 析：11. D. 空格后出现不可数名词(evidence/证据)， 因此答案只能来自B和D。 前句说“但是在2001年， 丹麦的研究者查看了100多项研究，他们发现有很多?很少? 证据证明因为安慰剂而使病人痊愈。”， 这一句句意发生转折(前文中说安慰剂)还有一点作用， 因此空格处应该填little(很少， 几乎没有)。
12. C. C 是文章主题词， 填入空格中句意通顺。
13.A. 如果B(正确的)能填入空格中， 则C和D也能填入空格中， 因此这三个选项彼此排除掉， 答案只能选择A(错误的)。
14.D. D(比较)填入空格中， 句意通顺(他们说最好把新药和现存的药进行比较)。
15. A . A (是否)填入空格中句意通顺(那样的话，研究将证明是否这种新药更有效)。
