A classic series of experiments to determine the effects of overpopulation on communities of rats was conducted by a psychologist，John Calhoun．In each experiment，an equal number of male and female adult rats were placed in an enclosure（场地）．The rat populations were allowed to increase．Calhoun knew from experience approximately how many rats could live in the enclosures without experiencing stress due to overcrowding．He allowed the population to increase to approximately twice this number Then he fixed the population by removing the children that were not dependent on their mothers．At the end of the experiments，Calhoun was able to conclude that overcrowding causes a breakdown in the normal social relationships among rats，a kind of social disease．The rats in the experiments did not follow the same patterns of behavior as rats would in a community without overcrowding．

       The females in the rat population were the most seriously affected by the high population density（密度）．For example，mothers sometimes deserted their children，and，without their mothers’care，the children died．The experiments showed that in overpopulated communities，mother rats do not behave normally．Their behavior may be considered diseased and pathological（病理学的）．

       The leading males in the rat population were the least affected by over population．Each of these strong males claimed an area of the enclosure as his own．Therefore，these individuals did not  experience the overcrowding in the same way as the other rats did．．However leading males did behave pathologically at times．Their antisocial（反社会）behavior consisted of attacks on weaker male，female，and immature rats．This unusual behavior showed that even though the leading males had enough living space，they too were affected by the general overcrowding．

       Non-leading males in the experimental rat communities also exhibited unusual social behavior．Some withdrew（缩回） completely ,avoiding contact with other rats．Other non-leading males were too active，chasing other rats and fighting each other．

       The behavior of the rat population has similarity in human behavior．People in densely（密） populated areas exhibit unusual behavior similar to that of the rats in Calhoun’s experiments．In large urban areas，such as New York City，London，and Cairo，there are deserted children．There are cruel，powerful individuals，both men and women．There are also people who withdraw and people who become too active．Is the major cause of these disorders（混乱）overpopulation?

       Calhoun’s experiments suggest that it might be．In any case，social scientists and city planners have been influenced by the results of this series of experiments．

Which of the following inferences（推断）can NOT be made from the first paragraph?

       A．Overpopulation causes pathological behavior in rat populations．

       B．Calhoun had experimented with rats before．

       C．Calhoun’s experiment is still considered important today

       D．Stress does not occur in rat communities unless there is overcrowding．

The author implies that the behavior of the leading male rats is sometimes similar to that of

       A．people who would like to keep to themselves 

       B．people who abandon their children

       C．too active people

       D．cruel，powerful people

The main point of this passage is that _______________．

       A．although rats are affected by overcrowding，people are not

       B．overcrowding may be an important cause of social pathology

       C．the social behavior of rats is seriously affected by overcrowding

       D．Calhoun's experiments have influenced many people

Americans can travel almost anywhere they choose. But to protect its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the traveller might not be safe. These countries are listed in a small book called a passport（护照）.
This passport is a government request for the safety of its travelling people. It is also a government’s pledge（保证） that the people will obey the rules of the host country（东道国）.
To receive a passport from the government, a traveller must prove that he is an American citizen （公民）. An American can not go overseas（外国） without a passport. Only certain close countries such as Canada and Mexico do not ask for passports.
Pasted （粘贴）inside the passport is the traveller’s picture. Children travelling with their parents are included in one parent’s book.
Thousands of people from the United States visit other countries every year. An American traveller might carry plane tickets, money, clothing and many other things. But the most important that he carries in another country is his passport.
68. A passport is not needed when an American goes to ______.
A. foreign countries   B. dangerous areas   C. Canada or Mexico   D. countries overseas
69. From the passage we can see that ______.
A. children can’t travel to foreign countries     B. Americans like to travel
C. a traveller is not safe in most countries      D. Americans like to travel to close countries
70. Why does a traveller need a passport?
A. He needs something more to carry when he travels.
B. It helps the country to protect the people.

When American students graduate from college, they must find jobs for themselves. But often they get help from their college and university. Every college has a career counseling office. The people who work there help students learn about different kinds of jobs and the chances for employment. Students can discuss their first year of college. Some use the information a counselor gives them when deciding what subjects to study.
For example, a girl student wants to be an engineer, but she does not know what kind. The counselor can tell the girl that, when she graduates in four years, there will be more jobs for structural engineers than for chemical engineers. Therefore, the student may study structural engineering.
The career counseling office also communicates with local and national companies. Company officials often visit the university to talk to students who want to work for them. The career counseling offices arrange these meetings for the company and the students. They also have classes for students. They teach the students how to find a job such as what to say to company officials and how to write letters telling about themselves.
Experts say that American students who are employed when they finish college usually find jobs in their own field of study. Those who must search for months after graduation usually take lower paid jobs, and their jobs are not connected to what they studied in college. The experts foretell that in coming years there will be more jobs for healthy workers, financial experts, teachers and computer scientists.
52．According to the passage, a career counselor______.
A．helps students pass the examinations successfully

These days, there’s a popular cartoon named happy sheep and gray wolf. It’s an excellent Chinese cartoon, which tells the stories of happy sheep and gray wolf. The poor gray wolf is always trying hard to catch the sheep, but the sheep could always run away from the danger. The sheep are so clever and lovely that the cartoon gets all the children’s love. At the same time, the cartoon is full of humor. The children could learn more knowledge and enjoyment from it.
The cartoon is shown repeatedly on many TV channels.The Zhejiang Channel broadcasts the cartoon on weekends and the vacations; the Sichuan Channel broadcasts the cartoon for an hour in the evening; the Shandong Channel broadcasts it in the morning, while CCTV-3 broadcasts it at noon every day.
On one hand, the cartoon gets the children’s love because the happy sheep is really clever. He always has a way to work out any problem and save his friends. What’s more , there’re many things about happy sheep and gray wolf, such as the books, the toys, the pencil-box, the clothings, and so on. Children are happy to buy them. On the other hand, many adults (大人) also like the cartoon, for the gray wolf is regarded as the perfect husband with skills and effort. He invents many things just to catch a sheep for his wife. Though he is often hit by his wife, he always makes her happy without complaining (抱怨).
We can learn more from the cartoon, including the skills, the stories, the details, the humor, and so on. We could see the humor of Chinese type during the cartoon. But I don’t like its being shown so often. It may make the children spend more time on watching TV and it is bad for their health and study.
【小题1】The underlined word “cartoon” in the first paragraph is ________.

A is for always getting to work on time.

B is for being extremely busy.

C is for the conscientious（勤勤恳恳的） way you do your job.

You may be all these things at the office, and more. But when it comes to getting ahead, experts say, the ABCs of business should include a P, for politics, as in office politics.

Dale Carnegie suggested as much more than 50 years ago: Hard work alone doesn’t ensure career advancement. You have to be able to sell yourself and your ideas, both publicly and behind the scenes. Yet, despite the obvious rewards of engaging in office politics—a better job, a raise, praise—many people are still unable or unwilling—to “play the game”.

“People assume that office politics involves some manipulative（工于心计的） behavior,” says Deborah Comer, an assistant professor of management at Hofstra University, “But politics derives from the word ‘polite’. It can mean lobbying（游说）and forming associations. It can mean being kind and helpful, or even trying to please your superior, and then expecting something in return.”

In fact, today, experts define office politics as proper behaviors used to pursue one’s own self-interest in the workplace. In many cases, this involves some forms of socializing within the office environment—not just in large companies, but in small workplaces as well.

“The first thing people are usually judged on is their ability to perform well on a consistent basis,” says Neil P.Lewis, a management psychologist. “But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It’ s simple human nature.”

Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people, they say, have an idealistic vision of work and what it takes to succeed. Still others associate politics with flattery(奉承), fearful that, if they speak up for themselves, they may appear to be flattering their boss for favors.

Experts suggest altering（改变） this negative picture by recognizing the need for some self-promotion.
