    ★Some kids run away because they have problems with their families.

    ★Some kids run away because they're afraid to tell their parents the bad things that they did at school or in society.

    ★Some kids run away because there is violence(暴力) in the family.

    What will you do if your friends want to run away from home?

    If your friend is thinking about running away, tell him or her that it is difficult to survive(幸存) in the streets. Try to help your friend feel less alone.

    Whatever the problem is, there are other ways to solve it. Maybe you can't think of the ways right now, but an adult(成年人) will know how to help you. You should tell an adult that your friend plans to run away as soon as possible. Being a real friend doesn't mean keeping a secret that may hurt someone. And running away isn't a solution(解决方法) for either of you. It only makes more problems and danger.

    Tyler opened the door to his house and went inside. His mother was in the kitchen. She felt surprised when she saw his sad face. “Tyler, what happened? Is everything okay?” “Nothing is okay, Mom.” “Is there anything I can do to help?” “That's just the thing, Mom. We can't help. There's nothing we can do.” Tyler kept talking,“Today, the teacher talked about Earth Day and the environment. Earth Day is a day when every person promises to do something to help take care of our world. Mrs. Green said that our world is getting dirtier and that many animals and plants are dying. She wants us to think of something we can do to help and I thought all the way home and there is nothing I can do. I can't stop people from polluting our air and water and I can't save all of the animals. There is not anything that I can do to make a difference.”

    His mother listened and after thinking for a minute said,“Of course you can. There are lots of things you can do. For example, you can walk to school. You can use both sides of your paper to save trees. You can plant a tree every year. You can clean up rubbish from your neighborhood park. Everything you do to help the planet makes a difference. The most important thing to remember is that Earth Day should be every day!” “Oh, I see. Mom, we each can make a difference to the world. Thank you, Mom.”

    Not only adults but also teenagers have problems in their life. Here is a survey showing the main problems of teenagers.

    They feel stressed because they have too much homework to do both at school and at home. They have lots of exams to take. And parents usually send them to different classes at weekends. (3)They don't have their own time to do what they are interested in.

    Now more and more teenagers are getting short-sighted. They often read in bed or keep reading for a long time without having a rest. Some of them are crazy about playing computer games. Some spend too much time watching TV. (4)Another serious problem among teenagers is that many of them are becoming fat. They eat too much junk food, but they take little exercise.

    I think teenagers should think of ways to deal with the problems. They should make a plan for study and hobbies and find time to relax as much as possible.
