1、Sometimes people call each other “scared-cat”, but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood- stream.

Although the cat doesn’t    16   this, its body is getting ready for action.

If the danger continues, this animal will do one of the two things. It will   17   itself, or it will run away as fast as it can.

  18  , when people are excited, angry, scared, or aroused by other emotions, our bodies also go through many   19   changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves   20   run.

Human beings,   21   , have a problem that animals never face. If we give way to our feelings and let them   22   , 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 someone you were lonely, or said you were in love, and then   23   later you had kept your mouth shut? It isn’t always   24   to express your feelings freely.

Does this mean that it’s smarter always to   25   our feelings? No! If you   26   feelings of anger, sadness, and bitterness hidden away or bottled up inside, your body stays   27  . Physical illnesses can develop. It can actually be   28   for your health.

Feelings that you keep all bottled up inside, don’t just   29   . It’s like you bought some bananas and stuck them in a cupboard. You might not be able to see them, but   30   you’d smell them. And if you opened the cupboard, you’d   31   little fruit flies hovering (盘旋) all over them. They’d be rotten.

You can try to treat emotions   32   they were bananas in the cupboard. You can   33   they don’t exist, but they’ll still be   34  . And at last you’ll have to   35   them. Just like those bananas.
