Questions are based on the following passage.

Cocoa contains chemicals calledflavanols （黄烷醇） that may help reduce the risk of strokes and heart attacks by lowering blood pressure and improving the body"s use of insulin （胰岛素） .

Washington chocolate producer Steve Kumar said that is one reason dark chocolate is increasingly popular among his customers. "A lot of people are attracted by dark chocolate because they just decide they love it， and they also have been reading all about the health benefits of dark chocolate，" said Kumar.

But those benefits have not been confirmed by studies involving large numbers of people. Also， during the production of chocolate， a lot of flavanols are destroyed， while sugar and fats are added to contribute to flavor.

Scientists now want to learn the benefits of flavanols in their pure form.

They plan a four-year study of 18，000 adults， who will take pills of pure cocoa flavanols， in what is being called the largest test of its kind. Jo-Ann Manson， of the Brigham and Women"s Hospital in Boston， is the lead researcher. "This pill of cocoa flavanols will avoid having the calories and the sugar and the fat found in chocolate，" said Manson. The pills also won"t have any taste. Participants，divided in two groups， will take two identical pills a day. One group"s pills will contain flavanols， while the others will getplacebo （安慰剂） pills. "The amount of chocolate that it would take in order to have this amount of cocoa flavanols would be more than ten times the amount that people would ordinarily eat，" said Manson.

Whatever the outcome of the study， Kumar said he"s not worried about his business. "People like the experience of actually biting into a piece of chocolate，whatever their favorites are，" he said.

The flavanol benefits test is still in the early stage， so scientists are not sure when the participants will be handed their first chocolate pills.

What chemical in cocoa may do good to the heart according to the passage？查看材料

A.Fat.

B.Insulin.

C.Sugar.

D.Flavanols.

Questions are based on the following passage．He was a qualified doctor who rarely practice

Questions are based on the following passage．

He was a qualified doctor who rarely practiced but instead devoted his life to writing．He once said: "Medicine is my lawful wife, and literature is my lover．" Russian writer Anton Pavlovich Chekhov was a great playwright and one of the masters of the modem short story．

(77) When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family． After he graduated, he wrote regularly for a local daily newspaper．

As a writer he was extremely fast, often producing a short story in an hour or less． Chekhov&39;s medical and science experience can be seen through the indifference（冷漠) many of his characters show to tragic events． In 1892, he became a full time writer and published some of his most memorable stories．

Chekhov often wrote about the sufferings of life in small town Russia． Tragic events control his characters who are filled with feelings of hopelessness and despair．

It is often said that nothing happens in Chekhov&39;s stories and plays． He made up for this with his exciting technique for developing drama within his characters． (78) Chekhov&39;s work combined the calm attitude of a scientist and doctor with the sensitivity(敏感）of an artist．

Some of Chekhov&39;s works were translated into Chinese as early as the 1940s． One of his famous stories, The Man in a Shell (装在套子里的人), about a school teacher&39;s extraordinarily orderly life, was selected as a text for Chinese senior students．

Questions （1）to（5） are based on the following passage:What makes a person a scientist？

Questions （1）to（5） are based on the following passage:

What makes a person a scientist？ Does he have ways ---or tools ---of learning that are different from those of others？ The answer is no. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the condition permit. What works under one set of conditions at one time mustwork under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was latter tested through investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations.

（1）A sound scientific theory should be one that .

A) works under one set of conditions at one time and also works under the same conditions at other times

B) leaves no room for improvement

C) does not allow any change even under different conditions

D) can be used for many purposes

（2）What, according to the passage, makes a scientist？

A) The tools he uses.

B) His ways of learning.

C) The way he uses his tools.

D) The various tools he uses.

（3） Albert Einstein built up his theory of relativity through .

A) investigation

B) experiments

C) tests

D) mathematics

（4）“…Knowing how to investigate, how to discover information, is important to everyone.” The author says this to show .

A) the importance of information

B) the importance of thinking

C) the difference between scientists and ordinary people

D) the difference between carpenters and ordinary people

（5） What is the main idea of the passage？

A) Scientists are different from ordinary people.

B) The theory of relativity.

C) Exactness is the core of science.

D) Exactness and way of using tools are the key to the making of a scientist.

Questions下列各 are based on the following passage. A newstudy shows a large gender gap on

Questions下列各 are based on the following passage.

A newstudy shows a large gender gap on economic policy among the nations professional economists,a divide similar to the gender divide found in the general public.

"Asa group, we are pro-market," says Ann Marl May, co-author of the study anda University of Nebraska economist. "But women are more likely to acceptgovernment regulation and involvement in economic activity than our malecolleagues. "

"Itsvery puzzling," says free market economist Veronique de Rugy of the Mercatus Center at George Mason University. "Not a .day goes by that Idont ask myself why there are so few women economists on the free market side."

A nativeof France, de Rugy supported government intervention (干预) early in her life butchanged her mind after studying economics. "We want many of the samethings as liberals--less poverty, more health care--but have radicallydifferent ideas on how to achieve it. "

IAberaleconomist Dean Baker, co-founder of the Center for Economic Policy andResearch, says male economists have been on the inside of the profession,confirming each others antiregulation views. Women, as outsiders, "aremore likely to think independently or at least see people outside of theeconomics profession as forming their peer group," he says.

Thegender balance in economics is changing. One-third of economics doctorates (博士学位) now go to women."More diversity is needed at the table when pubflc policy isdiscussed," May says.

Economistsdo agree on some things. Female economists agree with men that Europe has toomuch regulation and that Wal-mart is good for society. Male economists agreewith their, female colleagues that military spending is too high.

Thegenders are most divorced from each other on the question of equality forwomen. Male economists overwhelmingly think the wage gap between men and womenis largely the result of indi~fluals skills, experience and voluntary choices.Female economists overwhelmingly disagree by a margin of 4-to-1.

Thebiggest disagreement: 76% of women say faculty opportunities in economics favormen. Male economists point the opposite way: 80% say women are favored or theprocess is neutral.

What is the finding of the new study？

A.The gender divide is a big concern of the general public.

B.Men and women understand economics quite differently.

C.The gap between male and female economists needs to be closed.

D.Male and female economists disagree widely on economic policy,

听力原文：M: Can we make you an offer？ We would like to run the campaign for four extra wee

ks.

W: Well, can we summarize the problem from our point of view？ First of all, the campaign was late. It missed two important trade fairs. The ads also did not appear into key magazines. As a result, the campaign failed. Do you accept that summary of what happened？

M: Well, the delay wasn't entirely our fault. You did in fact make late changes to the specifications of the advertisements.

W: Hmm, actually, you were late with the initial proposals, so you had very little time. And in fact, we only asked for small changes.

M: Well, whatever. Can we repeat our offer to run the campaign for four extra weeks？

W: That's not really the point. The campaign missed two key trade fairs. Because of this, we're asking you either to repeat the campaign next year for free, or we only pay 50% of the fee for this year.

M; Could we suggest a 20% reduction to the fee together with the four-week sustention to the campaign？

W: We are not happy. We lost business.

M: I think we both made mistakes. The responsibility is on both sides.

W: Ok, let's suggest a new solution. How about a 40% cut in fee, or a free repeat campaign？

M: Well, let's take a break. We're not getting very far. Perhaps we should think about this.

Questions 22 to 25 are based on the conversation you have just heard.

22. What do we learn about the man's company？

阅读：The oldest and simplest method, then of describing differences in personality was to classify

Questions 36 to 40 are based on the following passage:

The oldest and simplest method, then of describing differences in personality was to classify people according to types, and such a system is called a Typology. A famous example of this method was set forth in Greece about the year 400 BC.A physician named Hippocrates theorized that there were four fluids, or humors, in the body. Corresponding to each humor, he believed, there existed a definite type of personality.

The four humors were blood, yellow bile, black bile, and phlegm. A person in whom all four humors were in perfect balance had a harmonious personality. If a person had too much blood, he was called sanguine(血红色), or cheerful and optimistic. Someone with too much yellow bile was choleric, or irritable and easily angered. Too much black bile made a person melancholy, or depressed and pessimistic. An oversupply of phlegm caused a human being to be phlegmatic, or slow and unfeeling. Scientists have long since discarded Hippocrates’ fluid theory. But the　names of the humors, corresponding to these temperaments, have survived and are still useful, to some extent, in describing personality.

Other features of people, such as their faces and physics, have also been used to classify personality. Today, however, personality theories and classifications　may also include factors such as heredity(遗传特征), the environment, intelligence , and emotional needs. Psychology, biology, and sociology are involved in these　theories. Because of the complexity of human personality, present day theories are often very different from one another. Psychologists vary in their ideas about what is most important in determining personality.

36.According to Hippocrates’ fluid theory, a man with too much phlegm will be ____.

A.optimistic B.easily angered C.unexcitable D.pessimistic

37.The main idea of this passage is about ____.

A.the complicated factors in determining one’s personality

B.Hippocrates’ fluid theory and its development

C.the past and today of personality classifications and theories

D.different personalities and their details

38.At present, psychologists ____.

A.have common opinion about personality theories and classifications

B.use biology, archaeology and sociology to study personality theories

C.have abandoned Hippocrates’ fluid theory entirely

D.all agree that human beings are characterized with complex personalities

39.The third paragraph mainly talks about ____.

A.Hippocrates’ fluid theory

B.scientists’ points of view on Hippocrutes’ fluid theory

C.Hippocrates’ fluid theory and its fate

D.defects in Hippocrates’ fluid theory

40.According to this passage the factors which are still NOT used to clas sify personality are ____.

A.one’s born features and needs of love and success

B.one’s height and weight

C.one’s hobbies and ideals

D.the environment and intelligence

根据下列材料，请回答下列各题： Passage One Questions 56 to 60 are based on the following pas

sage. Living in a time when an ever-increasing number of news providers push a constant stream of headlines at us every day, people cannot say they do not feel overwhelmed. But what of its the ways we choose to read the news that make us feel overwhelmed？ An interesting new study conducted by Avery Holton and Iris Chyi from the University of Texas looks at the factors that contribute to the concept of information overload. They surveyed more than 750 adults on their digital consumption habits and perceptions of information overload. What the findings suggest, Holton said, is that the news platforms a person is using can play a bigger role in making him feel overwhelmed than the sheer number of news sources being consumed. So even if you read The Huffington Post and The New York Times in a day, you may not feel as drowned with news ff you read on your phone instead of on your desktop. The more contained, or even constrained, aplat form. feels, the more it can contribute to people feeling less overwhelmed, Holton said. That may also explain why people have feelings of being overwhelmed by Facebook, which like reading on the web, can be a bottomless hole of stories, videos, and endless links. But it doesnt explain why people in the survey had different feelings towards Twitter, which can also be a stream of links. One possible explanation is whether you define yourself" as a news fan. The survey asked people to report. how much they enjoyed keeping up with the new——people who said they did had less of a perception of information overload. If youre the type of person who wants to follow news during the day, its likely you have an established routine and a set of sites you check regularly. You also may not need as much context around the news. All of that would make Twitter a good source for you. Conversely, if youre more passive about following the news, you might need to make more , of an effort to find the right sources or find background or contextual information, which could lead to feelings of being overloaded, Holton said. "Knowing what youre looking for can decrease overload or perceptions of overload. So can constant engagement," he said. The new study conducted by Avery Holton and Iris Chyi

A.examines how news providers take advantage of headlines

B.studies what can lead to the concept of information overload

C.discusses solutions for people who feel overwhelmed

D.reviews different attitudes to the digital consumption
