【题目】Kid’s health: Four steps for fighting stress

Everybody gets stressed from time to time. 【1】 Some ways of dealing with stress—like screaming or hitting someone-don’t solve(解决)much. But other ways, like talking to someone you trust, can lead you to solving your problem or at least feeling better.

Try taking these four steps the next time you are stressed:

(1)Get support. When you need help, reach out to the people who care about you. Talk to a trusted adult, such as a parent or other relatives. 2 They might have had similar problems, such as dealing with a test, or the death of a beloved pet.

(2)Don’t take it out on yourself. Sometimes when kids are stressed and upset they take it out on themselves. Oh, dear, that’s not a good idea. Remember that there are always people to help you. Don’t take it out on yourself. 3

(3)Try to solve the problem. After you’re calm and you have support from adults and friends, it’s time to get down to business. 4 Even if you can’t solve it all, you can solve a piece of it.

(4)Be positive. Most stress is temporary(暂时的). Remember stress does go away, especially when you figure out the problem and start working on solving it.

These steps aren’t magic, but they do work. And if you can stay positive as you make your way through a tough time, you’ll help yourself feel better even faster. 5

A. Ask for a helping hand to get you through the tough situation.

B. Notice your friends’ feelings and find a way to help them.

C. Different people feel stress in different ways.

D. Ah, it feels so good when the stress is gone.

E. You need to figure out what the problem is.

F. And don’t forget about your friends.

G. Then, find a way to calm down.
