Water is the most common substance(物质) found on the earth, but less than 1% of the earth’s water is suitable for drinking. More than 1,000,000,000 people around the world survive on just over 1 galon of water a day. Probebly more than 3,000,000,000 people may suffer from not having enough water by the year 2025. You are considered lucky if you live in a country where you can drink water out of your kitchen tap or bathroom tap. People in some countries have to pay for drinking water at home. So clean water is one of our most valuabe natural resources(资源).
In fact, peole waste so much clean water today. In factories lots of water is wasted. At home many people are not taking showers but still baths, and many are brushing their teeth with the tap turned on. Children are no longer taught how to save water….
You can save clean water in many ways. For example, if you keep gold fish, the tank water excellent for graden plants. And when you wash a milk bottle, pour the water on your house plants. Putting a brick or a water into your toilet tank many help use less water, saving many gallons over a long time.
Using rainwater is another simple way to save clean water. You can use rainwater to wash your hands after gardening, flush the toilet, and wash your car, your pet, your driveway when they are dirty.
For the same reason, people in Malaysia are encourageed to use rainwater. If one has a house with a small garden, he would buy a huge plastic tank to keep rainwater for their daily life.

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.”

B. They don’t care about costs.

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.
D. By giving examples.
