听力原文： Well, I manage a small branch of a large super-market, and we lose a lot of money through shoplifting. I have to try to prevent it or else I'll lose all my profits. A lot of shoplifting is done by young people, teenagers in groups. They do it for fun. They're not frightened so we have to make it difficult for them. Obviously a supermarket can't have chains or alarms on the goods, so we have store detectives, who walk around like ordinary shoppers, otherwise they'll be recognized. We have big signs up, saying: "shop-lifters will be prosecuted," but that doesn't help much. We've started putting cash desks at all the exits, we've found we have to do that, or else the shoplifters will walk straight out with things. Of course, that worries the ordinary shopper who hasn't found what he wanted. We also use closed-circuit television, but that's expensive. In fact all good methods of prevention are quite expensive, and naturally they make our prices more expensive, but it has to be done, otherwise shoplifting itself will make all the prices much higher, and the public doesn't want that!

We have a rather small house, with only one spare(多余的)bedroom. You can imagine (想像)our alarm(惊恐)when Aunt Clara wrote to say that she was coming with her children to stay for the weekend. Her family was not a small one, with four boys all under the age of twelve.
I sent off a telegram(电报)at once, explaining that our house was too small. Aunt Clara called us up the next morning. "I forgot to mention(提到)to you," she said in her sweetest voice, "the boys will be bringing their tents(帐篷)."
Even so ,my wife was still worried. It was true we had a large garden, but there was still the problem of feeding(喂养)four growing boys.
"And what if it rains？ she added.
Luckily Saturday morning turned out to be bright and clear when I went to the station to meet Aunt Clara. I pushed the boys, together with the luggage(行李) ,into the back of the car, with great difficulty of course. The youngest sat in front, with Aunt Clara and me.
On the way home. I talked over the shoulder(肩)to David, the eldest boy," I didn't see your tents among your luggage"
"The tents!" cried David. "My God! We left them at home."
We were not glad to have Aunt Clara's family with us because ______.
A．she and four boys
B．our house was small
C．it was the weekend
D．her family was not small

Food and Health
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to the diet as well, especially cancer of the colon (结肠). Different cultures are more likely to develop certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates (硝酸盐)commonly used to preserve color in meats, and other food additives, accused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin(青霉素) to beef and poultry(家禽),and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drags are administered to animals not for medicinal purposes, hut for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.
As a result of scientific intervention (介入) ,some harmful substances have been added to our food.
A．Right
B．Wrong
C．Not mentioned

Why Humans Walk on Two Legs
A team of scientists that studied chimpanzees (黑猩猩) trained to use treadmills(跑步机) has gathered new evidence suggesting that our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.
Michael Sockol, researcher of UC Davis, worked for two years to find an animal trainer willing to coax (劝诱) adult chimps to walk on two legs and to walk on ail fours.
The five chimps also wore face masks used to help the researchers measure oxygen consumption. While the chimps worked out, the scientists collected data that allowed them to calculate which method of locomotion (移动) used less energy and why. The team gathered the same information for four adult humans walking on a treadmill.
The researchers found that human walking used about 75 percent less energy and burned 75 percent fewer calories than quadrupedal and bipedal walking in chimpanzees. They also found that for some but not all of the chimps, walking on two legs was no more costly than on all fours.
"We were prepared to find that all of the chimps used more energy walking on two legs -but that finding wouldn't have been as interesting," Sockol said. "What we found was much more telling. For three chimps, bipedalism was more expensive, but for the other two chimps, this wasn't the case. One spent about the same energy walking on two legs as on all fours. The other used less energy walking upright." These two chimps had different gaits (步法) and anatomy (解剖) than their quadrupedal peers.
Taken together, the findings provide support for the hypothesis that anatomical (解剖学的) differences affecting gait existed among our earliest apelike ancestors, and that these differences provided the geneticvariation which natural selection could act on when changes in the environment gave bipeds an advantage over quadrupeds.
Fossil and molecular evidence suggests the earliest ancestors of the human family lived in forested areas in equatorial Africa in the late Miocene era (中世纪) some 8 to 10 million years ago, when changes in climate may have increased the distance between food patches. That would have forced our earliest ancestors to travel longer distances on the ground and favored those who could cover more ground using less energy.
"This isn't the complete answer," Sockol said. "But it's a good piece of a puzzle humans have always wondered about: How and why did we become human？ And why do we alone walk on two legs？"
Michael Sockol and his team were interested in
A．where humans came from.
B．how chimpanzees could be trained to use treadmills.
C．why our apelike ancestors came to walk on two legs.
D．when our earliest ancestors began to live in forested areas.

听力原文： Bad as well as good moods spice life and build character. The key is balance.
We often have little control over when we are swept by emotion. But we can hove some say in how long that emotion will last. Psychologist Dianne Tice of Case Western Reserve University asked more than 400 men and women about their strategies for escaping bad moods. Her research, along with that of other psychologists, provides valuable information on how to change a bad mood.
Of all the moods that people want to escape, rage seems to be the hardest to deal with. When someone in another car cuts you off on the highway, your thought may be, That jerk ! He could have hit me ! I can't let him get away with that! The more you stew, the angrier you get. Such is the stuff of hypertension and reckless driving.
What should you do to relieve rage？ One myth is that ventilating will make you feel better. In fact, researchers have found that's one of the worst strategies. Outbursts of rage pump up the brain's arousal system, leaving you much angrier, not less.
A more effective technique is "reframing," which means consciously reinterpreting a situation in a more positive light. In the case of the driver who cuts you off, you might tell yourself: Maybe he had some emergency. This is one of the most potent ways, Tice found, to put anger to rest.
Going off alone to cool down is also an effective way to defuse anger, especially if you can not think clearly. Tice found that a large proportion of men cool down by going for a drive—a finding that inspired her to drive more defensively. A safer alternative is exercise, such as taking a long walk. Whatever you do, don't waste time pursuing your train of angry thoughts.
Your aim should be to distract yourself.
The techniques of reframing and distraction can alleviate depression and anxiety as well as anger. Add to them such relaxation techniques as deep breathing and meditation and you have a store of weapons against bad moods. "Praying, "Dianne Tice also says, "works for all moods."

A．We can take control when we are swept by emotion.
B．We can control the length of time emotion lasts.
C．We can find the cause of emotion.
D．We can prevent bad emotions from happening.

第11题
There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes—the link between the two halves of the brain.
The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum. Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibers than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "What？" , and, if this difference exists, are there others？ Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution？ We tend to think that is the influence of society that produces these differences. But could we be wrong？
Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for wordhanding, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections.
But it isn't all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at "language subjects" and boys better at maths and physics. If these differences correspond with the differences in the hemispheric trunkline, there is an unalterable distinction between the sexes.
We shan't know for a while, partly because we don't know of any precise relationship between abilities in school subject and the functioning of the two halves of the brain, and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.
Which of the following statements is CORRECT？
A．Biologists are conducting research where psychologists have given up.
B．Brain differences point to superiority of one sex over the other.
C．Results of scientific research fail to support popular belief.
D．The structural difference in the brain between the sexes has long been known.
