Dr Wiseman started “the laugh lab” project in September 2001. It is the largest study of humour. Participants（參加者）are invited to log on to the laugh lab website, give a few personal details, tell their favourite jokes and judge the jokes told by other people.
　　The project will last for a year, and the organizers hope to finally discover the world’s funniest joke. But there is also a serious purpose. The researches want to know what people from different nations and cultures find funny. And they want to find out the differences between the male and female sense of humour. The idea is that if we want to understand each other, we have to find out what makes us laugh.
　　This is a subject that has long interested psychologists（心理學(xué)家）and philosophers（哲學(xué)家）. Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves.
　　By December 2001 over 10, 000 jokes had been submitted. This gave the scientists enough evidence （證據(jù)）to make early conclusions. It seems that men and women do have different senses of humour, for instance.
　　“Our findings show the major differences in the ways in which males and females use humour, ” said Dr.　Wiseman. “Males use humour to appear superior（優(yōu)越）to others, while women are more skilled in languages and prefer word play. ”
　　Researchers also found that there really is such a thing as a national sense of humour. the British enjoy what is usually called “toilet humour”. But the French like their jokes short and sharp: “You’re a high priced lawyer. Will you answer two questions for  500?” “Yes. What’s the second question?”
　　The Germans are famous for not having a sense of humour. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don’t know, but let’s say yes, just to be safe.
　　Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.
　　39．Scientist started“ the laugh lab” project________
　　A. to find the funniest joke in European countries
　　B. to know what funny people are from different nations and cultures
　　C. to find out the differences between the male and female sense of humour
　　D. to get more personal details about participants
　　40．We can infer from the passage that________.
　　A. most of the people all over he world are completely honest
　　B. psychologists and philosophers take interest in the “l(fā)augh lab” project
　　C. ordinary people are not interested in “the laugh lab” project at all
　　D. people tell the truth about themselves only when they laugh
　　41．What is the main idea of the 4th and 5th paragraph?
　　A. Man and woman have different senses of humour.
　　B. male and female have similar senses of humour.
　　C. About 10, 000 jokes have been submitted from September 2001 to December 2001.
　　D. Scientists have collected enough evidence to make conclusions.
　　42．The writer gave the examples of the British, the French and the Germans________.
　　A. to show that French people have a better sense of humour
　　B. to prove the British people have a sense of “toilet humour”
　　C. to show people from different nations have different senses of humour
　　D. to prove that the Germans have no sense of humour
　　43．Which statement is true according to the passage?
　　A. The jokes by computer are less funny than those by humans.
　　B. The Germans cannot find the submitted jokes amusing.
　　C. Males are better at word play compared with women.
　　D. Females like to use humour to show that they are superior.

Several days ago, a Beijing - based IT company fired about 400 people overnight. No one had expected the job cuts, which broke with traditional ways of letting go of workers in China. Moreover, what was special about this case was that the day before the 400 were fired, they all received from their boss a gift - the book “Who Moved My Cheese?”.
　　The book - a bestseller in the US - is being used by men and women to deal with changes in their lives and work. Some large organizations, including Coca- Cola, Kodak and General Motors, ask their employees to read it in order to encourage them to be active towards changes.
　　Cheese is something related to everyone’s livelihood - our jobs, the industries we work in, relationships and love as well.
　　With China’s official entry into WTO, the whole nation will face up to more changes and challenges. So what should we do once this “cheese” on which we are so dependent is moved?
　　“Whatever challenges and changes we meet, we should face up to them bravely” Jiang Hengwei, a civil servant said after reading the book.
　　Professor Yang in Renmin University of China agrees. “We should change our way of thinking. The coming competitive foreign companies and products provide us with great chances to learn from them and improve our own products to meet international standards and be more competitive.”
　　“With hard work and wisdom, we will create a much larger and better piece of cheese. ”Zhang smiled confidently.
　　44．The whole passage is about________.
　　A. a bestseller in the US
　　B. what people think about China’s entry into the WTO
　　C. people’s attitude toward changes and challenges
　　D. how a book influences the Chinese workers
　　45．The company in Beijing gave each of the 400 fired workers a copy of “Who Moved My Cheese” in order to________.
　　A. be more competitive with foreign firms
　　B. find an excuse for their job cuts
　　C. let the workers make a living on their own
　　D. encourage the fired workers
　　46．The word “cheese”in the passage can refer to________.
　　A. something we depend on for a living
　　B. a most important kind of food
　　C. change or challenge
　　D. way of life
　　47．From what Hengwei and Professor Zhang Yang said, we can know that________.
　　A. they have different opinions on changes and challenges
　　B. people are not afraid of competition from foreign companies
　　C. the Chinese people are ready to face any changes and challenges
　　D. they are both greatly encouraged by the book

If you don’t want people to know too much about you, then you had better keep your fridge contents secret according to a British market research document released last week.

    Researchers peered (凝視) into the fridges of 400 people in Britain and compared the contents with the owners’ lifestyles. They claim to be able to classify the nation’s people by fridge contents.

    They say those people can be separated into five categories："nutrition nerds (no social sense)", "food faddies (whatever’s in style)", "martyr mums", "fast food fanatics" and "restaurant regulars".

    "Nutrition nerds" care much about what they put into their bodies. Their fridges are stocked with fruit, vegetables and healthy meat.

    People in this category tend to be highly organized and usually work in law or accountancy. The vast majority are single, but if they have a partner, that person will be similar.

    A fridge full of vitamins ― enriched juices implies its owner works in media or fashion. They tend not to eat the foods they buy. Known as the "food faddies", they just want to be seen as purchasing the latest important things.

    A fridge filled with everything from steak to frozen fish suggests the "martyr mum". Her fridge tends to be stocked with every kind of product, except what she herself would want. This fridge hints at difficulty balancing family and work life.

    "Fast food fanatics" always buy mineral water for soda pop; the nearest they will get to fresh fruit is tomato sauce. Their fridges hint at someone who works hard and plays hard. Also, someone who is not into long term planning.

    Finally, a fridge filled with nothing more than a bottle of white wine and some sparkling mineral water implies an owner who is single, lives in a big city and enjoys the finer things in life. The fridge is empty because this person regularly eats in restaurants.

48．We can know from the first two paragraphs that ______.

   A．some researchers are fond of staring at other people’s fridges

   B．people don’t want others to know about their secrets

   C．the food you put in the fridge has something to do with your personality

   D．there are mainly five kinds of lifestyles among British people

49．According to the passage, people who belong to "food faddies" ______.

   A．don’t care much about money when buying things

   B．will try their best to stay healthy

   C．often stay up late to finish their job

   D．prefer to ask others about what to do next

50．What will those who often dine out put in the fridge?

   A．All kinds of food they like.                  B．Only something to drink.

   C．Fruit, vegetables and meat.                  D．Food rich in vitamins.

51．What might be the most suitable title for the text?

   A．Keep your fridge a secret                     B．You are what’s in your fridge

   C．What to put in the fridge?                    D．Be careful about your fridge

Botany, the study of plants, plays a strange role in the history of human knowledge. For many thousands of years it was one field about which humans had little knowledge. It is impossible to know today just what our Stone Age Ancestors knew about plants, but from what we can observe of preindustrial societies that still exists, a detailed learning of plants and their properties（特征）must be very ancient. This is reasonable. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been greatly important to the good of peoples, not only for food, but also for clothing, weapons, tools, medicines, housing, and a great many other purposes. Tribes(部落)living today in the woods of the Amazon recognize hundreds of plants and know many properties of each. To them botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all.

Unfortunately, the more industrialized we become the farther away we move from direct relation with plants, and the less clear our knowledge of botany grows. Yet everyone comes unconsciously on a surprising amount of botanical knowledge, and few people will fail to recognize a rose or an apple. When our New Stone Age ancestors, living in the Middle East about 10 000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer production the next season, the first great step in a new connection of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: planted crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the collected knowledge of tens of thousands of years of experience and close relations with plants in the wild would begin to disappear.

52. Which of the following assumptions（假設(shè)）about early humans is expressed in the passage?

A. They probably had wide knowledge of plants.

B. They clearly divided knowledge into separate fields

C. They did not enjoy the study of botany.

D. They placed great importance on ownership of property.

53.According to the passage, why has general knowledge of botany decreased?

A.     People no longer value plants as a useful resource.

B.      Botany is not recognized as a special branch of science.

C.      Research is unable to keep up with the increasing number of plants.

D.     Direct relation with a variety of plants has decreased.

54.In paragraph 2, the underlined word “marvel” is closest in meaning to _____.

   A. edge      B. sign      C. beginning      D. wonder

55. According to the passage, what was the first great step toward the practice of agriculture?

A.     The invention of agriculture tools and machines.

B.      The development of a system of names for plants.

C.      The discovery of grasses that could be harvested and replanted.

D.     The changing food of early humans.

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self- respect? The collection of happiness actions broadly categorized as "honor" help you create this life of good feelings.

      Here's an example to show how honorable actions create happiness.

     Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.

     Then, what is it to do with our sense of happiness?

     In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot lie trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased.  Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.

     There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

1. According to the passage, the positive action in the example contributes to our

A. self-respect                    B. financial rewards

C. advertising ability              D. friendly relationship

2. The author thinks that keeping silent about the uncharged item is equal to___.

A. lying         B. stealing         C. cheating        D. advertising

3. The phrase "bringing the error to the clerk's attention" (in para. 5) means___.

A. telling the truth to the clerk               B. offering advice to the clerk

C. asking the clerk to be more attentive

D. reminding the clerk of the charged item

4. How will we feel if we let the clerk know her mistake?

A. We'll be very excited.                 B. We'll feel unfortunate.

C. We'll have a sense of honor.            D. We'll feel sorry for the clerk.

5. Which of the following can be the best title of this passage.*

A. How to Live Truthfully                  B. Importance of Peacefulness

C. Ways of Gaining Self-respect             D. Happiness through Honorable Actions

書(shū)面表達(dá)：

Dear headmaster,

Knowing that our school is going to install air-conditioners, the students of our class had a heated discussion. Some students are for the plan while others are against it.

Students who are for the plan think that air-conditioners can make us comfortable both in summer and in winter. Besides, their families are well off and can afford the cost.

But other students think that air-conditioners can make the environment get worse, and air-conditioners will make a lot of noise which will have a bad effect on their studies. Meanwhile, installing air-conditioners will increase their economic burden.

In my opinion, I don’t agree to install air-conditioners. We are students, so we should pay much more attention to our study instead of seeking so-called comfortable conditions What’s more, the most important thing is that we should protect our environment as well.

With best wishes.

                                                                                           Yours,
