When I was a child, I hoped to live in the city. I think I would be happy there. Now I am living in a city, but I miss my home in countryside. There the air is clean or the mountains are green. Unfortunately, on the development of industrialization, the environment has been polluted. Lots of studies have been shown that global warming has already become a very seriously problem. The airs we breathe in is getting dirtier and dirtier. Much rare animals are dying out . We must found ways to protect your environment. If we fail to do so ,we'll live to regret it .

Dear Sir,

    How are everything going? I am writing to tell you that I have made a lot of progresses. But I would prefer to moving into a single room in next term, as I find it inconvenient(不便的) to share a room with others. My roommate often held parties at night, making much noise. Besides, his friends are always visiting him, that disturbs me a lot. So I hope to draw your attention to this problem. I am surely you will agree that the only solution for I is to get a room of my own, one not in the same building and as near to the school campus as possible. I would appreciate very much if you could do me the favor.

Best wishes.

Yours sincerely,

Li Ming

    Great changes have been taken place in my village. Ten years ago, the small and low houses of my village lie on the north of a lake. The villagers produced many waste. As a result, the lake was serious polluted. To the west of the village was a sandy field, where was the source of much dust.

    Now the poor house have been replaced by green trees. However, the sandy field that the villagers used to plough has been covered of fruit trees. On the lake, now clean and clear, the villagers often spend their spare time fish.

    In word, my village has become a green one.

    Yesterday morning I was on my way to work. Suddenly I stopped by a woman on the sidewalk. She asked me if I knew how to get to CASS, that is a local shelter for the homeless. I could tell she was extreme upset, so I told her I'd look it up for her on my smartphones. While waiting, she told the she was losing and didn't have money for the bus. I took out of a 20-dollar bill from my purse but handed it to her. Then I accompany her to the nearest bus stop. See the happy smile on her face brightened up my day, either.
