    I prefer my English classes to be taught in English only. What we all know, a good learning environment is of greatly importance if we want to study English well. Classes teaching in English provide students for a better environment. When English is an only language in class, students will have more opportunity to practise listening and speaking. However, there were problems with this method. Sometimes we may find difficult to follow the teacher and some slow learners may even give up learn English. In spite of these difficulties, but I believe practice makes perfect. With enough practice, we can overcome the difficulties and benefit from English classes in the long run.

    Yesterday, I saw the old lady fall down when I was hurrying to school. I was about to help her up while suddenly a passer-by stop me, saying that I might be accused of knocking him down. Heard his words, I began to hesitate and slowed down my step. At the same time, another student, who saw everything, went up to help. The old lady said nothing but lots of thanks to the good boy.

    What qualities do you think heroes should have? To me, heroes are brave and helpful. They're people you respect of. My heroes are the volunteers who go to the earthquake-hit areas last week. The disaster caused great damages to the areas. Therefore, the volunteers' efforts relieved the victims' suffering. They helped the victims by giving themselves food, water and shelter. They were also many doctors and nurses who volunteered help the wounded. The rescue work turned out dangerously, but no one showed fear nor gave up rescue the unfortunate people. I think nothing is equal to which the brave people did in the earthquake.
