I want to be a model student. What shall I do？

　　I should be polite. I should study hard. I should capful and helpful. I should walk in the corridors. I should throw rubbish in the bin. I should be quiet in the library. I shouldnt walk and run on the grass. I shouldnt throw rubbish on the floor. I shouldnt run in the corridors. I shouldnt fight. I shouldnt be noisy in the library.

　　One afternoon an old woman was crossing the street with a basket in her hand. She was going to do some shopping. Just then a car ran up fast and she was knocked down. One of her legs was hurt and she couldnt move any more. A kind cleaner saw whis and rushed to her at once. He helped her stand up and took her to the nearest hospital. What a warm-hearted man he was！

　　一天下午,一位老太太提着篮子过马路,她想去买点东西。就在这时一辆汽车快速开过来,老太太被撞倒了。她的一只腿受了伤,不能动了。一位好心的清洁工人看到了这个情景,便立刻向她冲过去。她帮助老人站起身来,并把她送到附近的医院。
