　　When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in the chemicals in its blood�瞫tream.If the danger continues,it will defend itself,or it will run away as fast as possible.

　　Something like this also happens to people.When we are excited,angry,scared or aroused(沖動) by others�� emotions,our bodies go through many physical changes,all of which make us more alert(警惕的) and ready to react.We also get ready to defend ourselves or run.Human beings,however,have a problem that animals never face.If we give way to our feelings and let them take over,we can get into trouble.Have you ever said something in anger—or hit somebody—and regretted it later? Have you ever shouted at a teacher,told somebody you were lonely,or said you were in love,and then wished later you had kept your mouth shut? It isn�餿 always wise to express your feelings freely.

　　Does this mean that it�餾 smarter always to hide our feelings? No! If you keep your feelings of anger,sadness,and bitterness hidden away or bottled up(掩飾) inside,your body stays tense.Physical illnesses can develop,and you can feel disturbed badly inside.It can actually be bad for your health.

　　You can try to treat emotions as if they were bananas in the cupboard.You can hide them and you can pretend they don�餿 exist,but they�餷l still be around.And at last you�餷l have to deal with them,just like those bananas.
