    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.

随着世界性能源危机的日益加剧,一向为人们所唾弃的垃圾也身价倍增,变成了能源再生的“宝库”。利用垃圾的一种方式就是将垃圾填埋后,通过厌氧发酵产生沼气,这些沼气燃烧,产生高温燃气,推动汽轮机转动,汽轮机驱动发电机来发电。

(1)根据上面的短文,请你将垃圾发电过程中的能量转化填写完整。

(2)垃圾填埋后产生的沼气是一种                   (填“可再生”或“不可再生”)能源。利用垃圾发电与传统的垃圾填埋处理方法相比有哪些优点(写出一条):                 

(3)若每吨填埋垃圾可产生沼气150m3,集中收集后可发电250 kw·h.巳知沼气的主要成分是甲烷,其热值为2.0×107J/ m3,则沼气发电的效率为多少?
