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

A simple flower made headlines (头条新闻)in the British press last week. How could that be? British Prime Minister David Cameron and his ministers were attending a reception hosted by Chinese Premier Wen Jiabao in the Great Hall of the People in Beijing. They insisted on wearing poppies (罂粟花) in their buttonholes.

What's wrong with that?

According to the Global Times, Chinese officials clearly had asked the UK delegation(代表团) not to wear poppies. The British said that poppies meant a great deal to them on that day and they would wear them all the same.

So what's the importance of the poppy? It's a flower which has different cultural and symbolic meanings for British and Chinese people.

From the Chinese point of view, the poppy is a symbol of China's humiliation at the hands of European powers in the Opium Wars of the 19th century. Britain forced China to open the borders to trade — including in the opium — which was made from poppies grown in India.

Yet from the British viewpoint the poppy is a reminder of the killing during World War Ⅰ. Red poppies grew on the battlefields of Flanders in Belgium where many thousands of British soldiers died or were buried. Since then, Poppy Day (November 11 ) has become a time in the UK to wear poppies and remember the sacrifices of British soldiers and civilians in times of war.

So you can see that the poppy sets off strong feelings in the hearts of Chinese and British people for different reasons.And it makes sense for us to try to understand each other's standpoint(立场).

Of course cultural differences can also be interesting and funny. And what one nation thinks is an acceptable gift may be viewed differently by their guest from overseas. US President Barack Obama gave a gift of an iPod to Britain's Queen — a dull person with no interest in music.  Obama also presented Gordon Brown with a fine selection of American movies. But they were in US format (模式)and impossible to play on British DVD players.

Many countries have diplomats(外交官) stationed overseas. Diplomats provide information and advice to their governments back home. However, sometimes it would seem that even diplomats can overlook (忽视)the cultural importance of a small flower.

64.British Prime Minister David Cameron probably attended a reception in Beijing on ________.

A.October 1   B.November 11    C.December 31   D.January 1

65.The poppy reminds the Chinese of________.

A.the shame caused by European countries in the 19th century

B.the British soldiers who were killed and buried during World War Ⅰ

C.the Chinese soldiers killed during World War Ⅱ

D.the suffering caused by Britain during World War Ⅰ

66.The diplomatic(外交的)problem in Beijing is mainly caused by ________.

A.the translation mistake      B.the language difference

C.the cultural difference       D.the different lifestyle

67.We can infer that ________.

A.Britain's Queen is not interested in art

B.Gordon Brown was fond of American movies US President Barack Obama sent him

C.US President Barack Obama received a gift for music

D.Britain's Queen may not like the iPod US President Barack Obama presented her

Sometimes doing something for yourself - even shopping--can give others a lift. That's the case at charity shops and non-profit stores such as Ten Thousand Villages which helps provide skilled workmen with money in developing countries.
Their handicrafts(手工艺品) are sold throughout North America in 180 stores, 95 of them operated by Ten Thousand Villages.
"People come into the store because we have a lot of interesting things, but then they're drawn to us by the mission(慈善的行动) ," says organization spokeswoman Juanita Fox.
"It just feels good to be making a difference when you're buying something."
In the Alexandria, Virginia shop, generals display windows draw you in. They are filled with practical, attractive home furnishings in blue and white, all international in mood.
Once inside though, it's clear that this isn't just another import store. On the wall behind the cash register is the following note:
"Ten Thousand Villagers provides necessary, fair income to Third World people by marketing their handicrafts and telling their stories in North America. Your Buying Makes a Difference. "
The store was opened in 1994 as part of a network of shops across the USA run by the Mennonite Church, which is based in Akron, Pennsylvania.
Currently, 60,000 skilled workmen from 32 countries provide goods to the stores, with all proceeds (收益) re-invested in the organization.
Management of the Alexandria shop is overseen by an all-volunteer board of directors. More than 40 additional volunteers help doing everything from working the register to unpacking stock.
Maria Yannopoulos got involved after visiting a store and getting to know another volunteer. "Since we are non-profit, we are really looking for value because the more we sell, the more jobs we can create. Giving someone job rather than charity helps in so many ways. "
【小题1】The underlined part "give others a lift" in the first paragraph means ______.

D
When a storm is coming, most people leave the area as quickly as possible and head for safety…But there are a few people who will get into their cars and go straight for the center of the storm.These people are willing to risk (冒…危险) being killed by floods or 100-Kilometer- an-hour winds for the excitement of watching the storm close up.
“Storm chasing (追逐)”is becoming an increasingly popular hobby (喜好) ,especially in the Midwest of the United States, where there are frequent storms between March and July.A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to l,000 kilometers to where the storm will be and waits for it to develop.
Although anyone can do it,storm chasing is extremely dangerous.The power of a big storm  can throw a cow into the air or destroy a whole house in seconds.Storm chasers are also often hurt in accidents caused by driving in a heavy rain.If you are a beginner, it is much safer to join a group for storm - chasing vacations during the storm season.
Even then,storm chasing is not all adventure and excitement.“Storm chasing is 95%driving,”says Daniel Lynch,who spends most of his summer storm-chasing.“Sometimes you
Can sit around for hours waiting for something to happen,and all you get is blue sky and a few light showers.”
However,for storm chasers,it is all worth it. “When you get close to a storm,it is the most exciting sight you will ever see in your life,”says Jasper Morley.“Every storm is an example of the power of nature.It is the greatest show on Earth.”

C.efforts in storm chasing are well paid
D.a storm presents the greatest show on Earth
