Do you know how a young dog or cat gets to know a new home? The animal uses its nose. Right away it smells its new places. Then it makes wider and wider circles, smelling all the time. Before long it can find its way home very well, even in the dark. It simply follows something it knows well.

Stories happen about animals who found their way across land they had never smelled before. Take the case of Smoky, a small white cat. Smoky had some funny red hair around its right ear. One day Smoky and his owner began a long journey. They were moving from Oklahoma to Tennessee. When they were just eighteen miles from their Oklahoma home, Smoky jumped out of the car. Then he found his way back to the old house. There he wandered around outside for many days. Finally he disappeared.

A year later Smoky meowed at the door of a house in Tennessee. A man opened the door. “Is that you, Smoky?” he said in surprise. At first he couldn’t believe it. Then he saw the red hair around its right ear. It was Smoky!

Having a teenager at home can be a real headache. Many teenagers smoke, drink and even fight. They often do something dangerous.

Earlier studies have shown that teenagers are more likely (可能) to make irrational decisions than people from any other age group, including children and adults. Is it that teenagers are too young to tell right from wrong? Not really. So what’s the reason?

According to Laurence, a teacher from a US university, the reason is that teenagers care a lot about how their peers (同齡人) view them—that is “peer influence”.

As children enter their teenage years, they spend more time with their friends and classmates, and also they care more about what they think of them. This makes teenagers make decisions without thinking about the costs.

In a test, a group of teenagers were asked to play a video driving game. When they played with their friends watching around them, they took more chances and drove more carelessly because that would increase their possibility of winning. But when they played alone, they drove more safely.

Why do peers have such a big influence on teens’ behavior?

As Laurence sees it, a teenager’s brain is like a car with a good accelerator (油門) but a weak brake (剎車). The “accelerator” is fully developed by teenage years while the “brake” is still not fully developed. When teenagers are watched by their peers, they usually push hard on the accelerator. With their weak brake, it is likely that they are going to end up in an accident.

But the good news is that a violent (暴力的)teenager doesn’t necessarily become a violent adult. About two-thirds to three-quarters of violent youth grow out of it. “They get more self-controlled.”

1.What does the underlined word “irrational” in the 2nd paragraph mean?

A. Quick. B. Crazy. C. Careful.

2.Why are teenagers likely to make wrong decisions according to the text?

A. They like difficult tasks.

B. They don’t care about costs.

C. They care a lot about what their peers think of them.

3.How does Laurence explain the influence of peer pressure on teens’ behavior?

A. By comparing it with how a car works.

B. By comparing it with an accident.

C. By showing research findings.

4.What can we learn from the text?

A. Teenagers are easy to have traffic accidents.

B. Peer influence is bad on teenagers.

C. Most of the teenagers become less violent when they grow up.
