    One day, when I am walking in my neighborhood after supper, I saw wallet on the ground. I picked it up or opened it. I found there were several $100 bills in it but I didn't know whom it belonged for as there was no information about the owners. Just as I was wondering how to deal with it, I saw a man look for something. I went to him and asked how he was trying to find. He said he had been lost his wallet. Then I asked him how many it was in it. I returned it to him after making sure the wallet was him. He couldn't thank me enough.

Dear Editor,

    Recently our school has set up a rule that no student allowed to take their mobiles into class, which has aroused a lot of discussions among we students.

    Many of the students feel strong against the rule, arguing that the mobile had become a necessary part of our life. They also consider that a must for us to get relaxing from our busy studies.

    When it comes to me, like some other student I hold a different opinion. While a mobile phone can help us get some relief, with it we can be more devoted to our studies, but spare more time to communicate with those around us. Therefore, I believe in this school rule is beneficial to every student.

Yours,

Li Hua

    It was Sunday yesterday. I didn't need go to school. So together with my friend, I went on a picnic. Carrying a bag of food, we set it out. The sky was blue but the air was fresh to breathe. We were very excited. All of the sudden, I felt my bike became very heavy. I realize there must have been something wrong with it. Sure enough, one of the tires got flatter. I had no choice but to walk. However, with two friends around me, I didn't feel disappointed. Late, a truck driver volunteered to get my bike repair. I was really lucky to meet such kind a man.
