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.

Last week, I have the honor of experiencing teaching. Our school asked some volunteer to teach some kids which lived in the countryside.

I treasured this chance so much and joined in the team. When I met those kids, they were so happily to see me and listened to me carefully. Given the warmest welcome by them, I enjoyed being their teacher. However, I tried my best to teach them and play games with them.

Back to school, I missed our students so much. They liked me a lot but some of them even kept in the touch with me. I felt so proud being a teacher. This precious experience helped me make up my mind to realizing my dream.

As new students at an university in Boston，many of us were unfamiliar with the campus but consequently late for class. One professor，however，was particular intolerant of being late，making clear that no excuse would be acceptable. So when a girl student came to his class one morning later，we expected the worst results. Then the professor demands the reason for her coming late.“I was being waiting online to buy your new book，”she replied very nervously. While looked at the rest of the class，the professor asked，“Well，why was not the rest of you late？”
