We know the mosquito very well. Mosquitoes fly everywhere. They can be found almost all over the world， and there are more than 2，500 kinds of them.

No one likes the mosquito. But the mosquito may decide that she loves you. She？ Yes，she. It‘s true that male mosquito doesn’t bite（咬） and only the female mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds， she bites. But if she doesn‘t like your blood，she will turn to someone else for more delicious blood. Next time a mosquito bites you，just remember you are chosen. You’re different from the others！

If the mosquito likes you，she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites，you will have an itch（痒） on your body because she puts something from her mouth together with your blood. By the time the itching begins，and she has flown away.

And then what happens？ Well，after her delicious dinner，the mosquito feels tired. She just wants to find a place to have a good rest. There，on a leaf or a wall， she begins to lay eggs，hundreds of eggs.

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 (同龄人) 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 (油门) but a weak brake (刹车). 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.”

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

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.
