阅读理解。

    Is there someone you hate? Well, maybe you don't really hate them. But you get really

angry every time you think of them. If you don't let this anger go, it can turn into

bitterness (痛苦).

    Bitterness appears when we can't forgive (原谅) someone who has hurt us or made us

angry. Someone might say or do something that hurts us. But instead of controlling the

anger, we keep it beep inside. Before long, a bitter feeling begins to grow. We may think

we're hurting that person by criticizing (指责) him or her often, but we're really only

hurting ourselves.

     Bitterness can not only lead to serious health problems such as heart disease, but

also hurt our relationships with friends and family members. No one enjoys being around

an angry person for very long.

    If you see bitterness in your life, here are some ways to deal with it. 

   ·Accept it

    Instead of trying to deny your anger, make it clear to yourself and accept it. See

your anger

   ·Stop making excuses for it

    You may feel you have a right to be angry.

    You may think you're right and the other person is wrong. You may even secretly enjoy

making the other person look bad. But in the end, bitterness hurts you much more than the

other person. The bitterness will hold you back, and the other person will go on with his

or her life.

   ·Forgive and forget it

    You probably can't completely put the anger out of your mind. But you can decide to

forgive the other person. Forget it and move on. You'll enjoy better heath and peace of

mind.
