【考點(diǎn)】說明文；環(huán)境保護(hù)．

【答案】We have only one earth and it's our home，so it's our duty to take care of it.If we harm it，it's unavoidable that we will have a terrible end.There is no doubt that protecting the environment is still worth people's attention in the new century.As teenagers，we are supposed to play an active role in improving the environment.
    Two years ago，my parents asked me to participate in a summer camp to improve my living ability.I spent different days there.One day，our head teacher invited us to the park.I thought it would be a relaxing trip，but when we got there，I was disappointed with everything I saw：so many plastic bags and bottles.So we began to clean it up.I felt very happy，bored and tired for what I had done.Finally，when the park was finally cleaned up，I felt a strong sense of satisfaction.This experience has taught me the importance of environmental protection，and we have the responsibility to call on more people to take action.As a teenager，I can do some small things to protect our environment，such as taking the bus to school.At the same time，I can wash my hands.I'm sure everybody is able to do something meaningful to make the world better.
