题目内容

【题目】One day, Amy is digging in the ground for a potato when along comes Tom. Seeing that there is no one in sight, Tom starts to scream. Tom’s angry mother rushes over and drives Amy away. Once his mum has gone, Tom helps himself to Amy’s potato.

We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Amy and Tom are not humans. They’re African baboons(狒狒).1

Tom’s scream and his mother’s attack on Amy could have been a matter of chance, but Tom was later seen playing the same tricks on others.2

Studying behavior like this is complicated but scientists discovered apes() clearly showed that they intended to cheat and knew when they themselves had been cheated.3An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”

Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe.4But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.

It seems that trickery does play an important part in ape societies.5Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.

AAn amusing example of this comes from a psychologist working in Tanzania.

BAnd playing tricks is as much a part of monkey behavior as it is of human behavior.

CSo the psychologists asked his colleagues if they had noticed this kind of trickery.

DOf course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

E. This use of a third individual to achieve a goal is only one of the many tricks commonly

used by baboons.

F. The ability of animals to cheat may be a better measure of their intelligence than their use

of tools.

G. In most cases the animal probably doesn’t know it is cheating.

【题目】Global warming happens when greenhouse gases trap heat and light from the sun in the earths atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out. As a result,the temperature rises.

Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it,so people,plants,and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat,and it would also limit the food that animals have. With less food for the animals that we need to/span> survive we would even have less food. Gradually,people,plants,and animals would all die of hunger.

People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now,more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming,kids call do just as much.

【题目】Personal computers and the Internet give people new choices about how to spend their time.

Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.

E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren't necessarily much shorter than they once were, but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she'd been born before electronic mail became such a practical tool.

The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun—see a great movie perhaps and there are four or five friends who might want to hear about it. If you call each one, you may be tired of telling the story.

With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.

E-mail is also an inexpensive way to stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.

We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don't take the place of any of the old ways.
