阅读A、B两部分内容，从各小题所给的四个选项中选出能回答所提问题或完成所给句子的最佳答案。

     Sometimes we feel good, such as when we get good grades or when something good happens.

Sometimes we feel bad, such as when we argue with our classmates or when the teachers criticize

(批评) us. Both kinds of feelings are common. Of course, we all enjoy good feelings, but when we feel

unhappy, sometimes we don't know what to do about it. Here is a plan that will help you when your

feelings are bothering you.

     ● ACCEPT your feelings.  Say to yourself  "I am sad. " "I am scared. " "I am angry. "  "I am

embarrassed. " It's all right to have these feelings.

     ● RELAX and have a rest before you act. Take slow deep breath (呼吸) and relax your body.

Imagine that you are in a safe place. You can listen to some music or sing a beautiful song!

     ● THINK about ways to help yourself. Thinking helps you do something smart instead of hurting

yourself or making things worse.

     ● DO something to help yourself. Maybe you can talk to someone, or do something you enjoy. If it

doesn't work, go back to Step 3.
