　　Give Up Or Not?

　　In the 2008 Beijing Olympic Games, the world-famous 100-meter huddle athlete Liu Xiang quit the race beyond expectation, which stirred up a debate among students.

　　The majority of the students hold the view that Liu Xiang made the right choice. If it hadn’t been absolutely necessary, he wouldn’t have quit. Giving up doesn’t necessarily mean weakness. Instead, giving up sometimes is a kind of wisdom and calls for courage. If Liu Xiang hadn’t dropped out, he could have suffered a more serious injury and left the running track forever, which no one would want to see.

　　In contrast, about 35% of the students hold the different opinion. They feel that Liu Xiang’s withdrawing from the 110m huddle disappointed the whole nation. What we expect from Liu Xiang is not a gold medal but his strong will. Even if he did not achieve his goal, he would win the respect of all.

　　In my opinion, it is wise of Liu Xiang to have quit the race. If his ankle had gotten injured again, how could he render more service to our country in the future? Let’s wish him a promising future.

　　Dear Editor,

　　Nowadays mobile phones are becoming more and more popular among the middle school students. In my opinion, we can bring mobile phones to school.

　　As we know, the 21st century is a modern age and full of information. A mobile phone is one of the quickest tools for us to exchange information. The mobile phone is a fashionable and useful invention, so we ought to make the best use of it. Suppose there’s a sudden accident, it is more convenient for us to dial for help immediately. There’re also some games in the mobile phone. We can relax ourselves by playing them when we’re tired of our studies. In my opinion, it’s not wrong to follow the fashion, but the most important thing is how to use the mobile phone in a right way.

　　Yours truly,

　　Wang Lin

　　作文Dear editor,

　　Recently our class have had a heated discussion on whether students should be accompanied by parents studying at school. Opinions are divided on the topic.

　　70% of my classmates hold the view that there is no need for parents to do so. For one thing, we may fall into the habit of dependence, which will have a negative effect on the development of our self-control ability. For another, it will affect our parents’ work, study and rest.

　　However, 30% of us are in favor of it. In their opinion, with parents accompanying us, we can spare more time to concentrate on our study and we will become more healthy. Furthermore, parents can help set our study goal and urge us to complete our study tasks. Also we can overcome difficulties on our own. with their encouragement and develop a good habit of studying.

　　Best wishes.

　　三、(One possible version)

　　I am Li Ming of Senior Three, from Guangming Middle School. I am writing to tell you about some symptoms of anxiety among us students before exams.

　　Most of us feel nervous whenever we‘re taking an important exam. Some will feel dizzy or tired， some will suffer from lack of sleep， and some will lose their appetite. In fact,all these symptoms have terrible effects on our exams and we are all eager to get rid of them.

　　First of all，in my opinion，it‘s important for us to have a fight attitude towards exams. They are only a means of checking how we are getting along with our studies,so there is no need to worry too much about the results. Study hard every day and make careful plans for every exam. In this way we can avoid suffering from the pressure of exams.　Besides,enough sleep can make us energetic and enable us to perform well in an exam. Therefore，during the period of exams，we should not stay up too late. We can also try a warm bath or a cup of warm milk before going to bed. They might help us to have a sound sleep.

　　We‘d better go out for a walk or do some outdoor exercises before and during an exam so that we can keep ourselves relaxed and then concentrate ourselves o
