Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.

   There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.

   Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.

   These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.

   We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.

   The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

It was a cold winter. The day my husband fell to his death, it started to snow, just 36 any November day. His 37 , when I found it, was lightly covered with snow. It snowed almost every day for the next four months, while I sat on the couch and watched it 38 . One morning, I walked slowly 39 and was surprised to see a snow remover clearing my driveway and the bent back of a woman clearing my walk. I dropped to my knees and crawled back upstairs, 40 those good people would not see me. I was 41 . My first thought was, how would I ever 42 them? I didn’t have the  43 to brush my hair, 44 clear someone’s walk.

Before Jon’s death, I felt proud that I 45 asked for favors. I identified myself by my competence（能力） and 46 . So who was I if I was no longer capable? How could I 47 myself if I just sat on the couch every day and watched the snow fall?

Learning to receive the love and 48 from others wasn’t easy. Friends cooked for me and I cried. Finally, my friend Kathy said, “Mary, cooking for you isn’t a 49 for me; it makes me feel good to be able to do something for you.”

Over and over, I heard 50 words from the people who supported me during those 51 days. One wise man told me, “You aren’t doing nothing because being fully open to your 52 may be the hardest work you will ever do.”

I am not the person I 53 was, but in many ways I have changed for the 54 . I’ve been surprised to learn that there is incredible freedom coming from 55 one’s worst fear and walking away whole. I believe there is strength, for sure, in accepting a dark period of our life.
