Last Sunday, my family went for walk in a nearby park. We wanted to breathe the fresh air and having fun there. However, when gone out, we found it was cloudy and smoggy (烟雾弥漫的). Only a few people were walking quick on the streets wearing their masks. I was wondering what was the matter when my little brother begins to cough loudly. Suddenly I realized that it was air pollution. So we had to go back to home that day. Smoke from cars, buses, and factories make the air dirty, that is harmful to our health. I think they all should do some thing to keep the air clean.

I tried a new lifestyle. I gave up the Internet, but even didn’t watch TV. I thought I would feel very boring. However, I had very different day. I wrote two article that morning. In the past, I always want to write one, but I didn’t have time. While I was separated from the Net and TV, I could devote me to writing. I once read an article, that said that every morning the writer spent two hours write without the Net. At that time, I thought of she was too strict. After I tried the method myself, I found it real worthwhile.

After we moved to a newly country，my three-year-old daughter and I was often alone in our house. Although we lived in the countryside with no close neighbors，I needed to prepare for some possible emergencies. For example，I wanted make sure my daughter would be able to call 911 in case of that something happened to me. After instruct her，I decided to test her. I asked her，"Okay，what will you do if you found me on the floor and you couldn't wake me up？" I could see his little brain working. Then to my surprises，she said，"I would go into the kitchen and eat anything I want." What the naughty girl！

The day, May 16th, is my younger brother's birthday. That afternoon I went to the shopping center downtown, and buy a present for him. Then I took the subway train home. Seating on the train, I thought my brother would be very happy when he saw a present.

At the next station, an old lady with two heavy bag got on the train and stood in front of me. She looked tiring. I didn't hesitate for a moment, but then offered my seat to him. The old lady thanked me for a lot and sat down. I felt joyfully when seeing her smile. I will always ready to help others in the future.

Doing good daily doesn't necessary mean helping other people. We can also do something good for other little creatures on this earth. Today, I was on my way to home and saw the turtle trying to cross the road. I stop my car, picked up and brought it to a river nearby. It was the rush hour but there were a lot of cars behind me. It took me about five minute to finish doing that. Although my action might be an inconvenience with other cars, I knew that save a life was well worth their waiting. In my mind. what I did was meaningless.

My new friend Tom is good at English writing. One day, I asked him how he did so well in written English. He told me that he has a habit of keep a diary every day. "You can try them, too. I'm sure you will improve your written English quickly in this way, "he said. I thought Tom was right, but I decided to follow his advices. I started to write down something interested every day. Sometimes when I didn't know why to spell a word, I would look it up in a dictionary. When I didn't know how to write a sentence correct, I would ask my teacher for the help. My written English has really improved a lot because that.

I'm a booklover but like sharing my love for books！So I've been bought books constantly. Finishing reading one book，I placed it in my school so that some of my schoolmate can enjoy themselves when reading it. I especial like placing it on a stone table in the little garden that students might have time to take a rest. I was delighted when I saw the card left on the table to say thanks the other day. And from the card，I knew my book turned out of to be a birthday gift for a strange girl. It was so lovely find out that my book could bring anyone pleasure！

One afternoon in February，my classmates and I were on the way to the cinema. Sudden an old woman fell down heavily due to the ground covering with thick ice. Seeing what have happened，we called 120 without a second thought. On such cold weather，we stayed with her until the ambulance came to scene. And then they left for the cinema. Although we were later for the interesting film，but we all thought it was worthwhile. After all，helping people in need is a good way to obtain joy and happy. Now we all remember the day when when we spent together.

A Chinese and a German made up their mind cross the sea in a balloon in 1754. The balloon in what they discovered a hole was high over the water. A hole became bigger and bigger. The hot air keeping the balloon up was escaping quick and the balloon was coming down. The two men threw all their equipments in order to make the balloon lighter. It started to rise higher again，so it was still too close to the water. At last，the men throw away most of their clothes to save himself. The crowd waiting for to welcome them was very surprising to see this when the balloon landed in front of them.

It isn't hard for everyone to grow up into a responsible members of society.

I can well remember an accident that happens on a rainy Sunday afternoon. I was on my way to bookstore and was waiting for the green light at a crossing when a girl of about ten was knocked down by a passing car, what drove off quickly. A man immediately rushed to the girl to give him first aid and I joined in without hesitation. Lucky she was not badly injured but we sent her to the nearest hospital. Comparing with the escaped driver, I am pride of what I did.

As a member of society, I am aware of that being responsible is what it takes to make a better society.
