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

Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student they always say, “My spoken English is poor.” However, their spoken English does not have to remain “poor”! I would like to suggest that there may be some reasons for their problems with spoken English.

First, they fail to find suitable words to express themselves due to a limited vocabulary. Obviously the better answer is to expand their vocabulary. However, you can speak with a limited vocabulary, if your attitude is positive. Others will follow you as long as you use the words that you know.

Second, they are afraid of making mistakes. Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY（准确性）. Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling them correctly. However, in speaking your aim is fluency. You want to get your message across, to talk to someone in English, as quickly and as well as you can, even though sometimes you may use a wrong word or tense, but it doesn’t matter because the person you are speaking to will understand you and make allowances for any mistakes he hears.

The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that hearing was necessary for you to start speaking.

Fourth, most Chinese students are reactive rather than proactive language learners. Instead of actively seeking out opportunities to improve their spoken English, they passively wait for speaking opportunities to come to them and wonder why their English always remains poor. If you have this proactive outlook, then you will see English opportunities wherever you go.

If you do not use your English beyond the classroom, you will forget what English you know. Remember: USE IT OR LOSE IT! You can learn how to speak English better by speaking English more.

What is most probably the writer’s purpose in writing the passage?

A．To improve your reading.                 

B．To improve your listening.

C．To improve your spoken English.        

D．To improve your vocabulary.

It can be inferred from the third paragraph that______.

A．don’t be fluency , Just be accuracy

B．don’t be nervous ,don’t be shy . Just write!

C．don’t be afraid of making mistakes . Just speak!

D．don’t be shy ,don’t be fluency. Just listen and write!

The last paragraph is possibly close to the meaning of “_____”.

A．more hurry, less speed             B．better late than never

C．silence is gold                    D．practice makes perfect

The text is most probably taken from a ______.

A．teacher’s diary                     B．report on study
