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.

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.
