The Problem of　 ‘Three Merits Student’

Professor Wang suggests abolishing the system of 'Three Merits Student'. Many schools pay close attention to students' academic achievements when they elect Three Merits Students. They ignore students' other abilities. In order to become Three Merits Students, a lot of students spend much time on study. Therefore ,they have no time for rest and sports, which greatly affects students' health.

　　 Many people agree with him．They think it is wrong to elect the Three Merits Students in the original way for it can't completely represent the all qualities of the students. It is sided. Besides, their self-esteem is seriously hurt.

　　 On the other hand, there are still a great many people who hold opposite opinions. They think it is an encouragement for the students because study is the most important task to the students.

　　 As far as I'm concerned, schools may elect the best student, but the standard had better be improved. We should praise those students who do well in every aspect in their school life including study, morality, sports and so on.

Passage 15

(江西省师大附中2009届高三第三次模拟考试)

最近，你校举行了“改革开放30年”征文活动，请结合下列图画，用英语写一篇120-150词左右的短文，内容包括：(1)图画所体现的变化；(2)你的感受。

参考词汇：改革开放the reform and opening – up

[参考范文]

It is 30 years since China carried out the reform and opening up. Great changes have taken place and each part of China can give a clear sign of the rapid development and advance in today’s China.

Take people’s communication for example. In the past, our grandpas had to ask someone who could write for help when they wanted to contact their relatives or friends. As for our fathers, they kept in touch with each other by writing letters by themselves. With the development of science and technology, we can communicate with each other anytime and anywhere by mobile phone.

As a new generation, we are so lucky living in the new century. We’re proud of our country and its achievements. So we should cherish the happiness of today’s life. Meanwhile, we should put more effort and make more contributions to our beloved motherland. We believe she will become stronger and stronger.

1、词数150左右。

2. 可适当增加细节，以使行文连贯

Mrs. Wang decided to make a trip to Beijing. When she told her son about her decision, he was so overjoyed that he jumped up and down. They began to pack their luggage. When the day came, the son became worried, for nobody would take care of his flower. It would die if it was not watered. Suddenly a good idea came to his mind. “Mum,” he said to his mother, “We can use a piece of cloth to take care of the flower.” He showed his mother what he meant by putting one end of the cloth into the basin, full of water, and other end into the flowerpot.

Five days later, when they came back from Beijing, the flower was still alive and even started to blossom.

Dear teachers and students，

Our government is trying hard to promote scientific development. It is everybody’s duty to work hard and reach this goal.

However, not everybody has realized the importance of it. Take our school for example. Sometimes we can see that lights and computers are still on after class. Some students even forget to turn off the tap after using it and have water running all the time. Our papers are printed on only one side, causing much waste.

It’s time we did something to avoid this kind of waste. Firstly, make sure that all the lights and other electric facilities are turned off when we leave the rooms. Try to form the habit of turning off the tap immediately after using it. What’s more, papers should be printed on both sides and reused if possible.

In a word, if everybody has the awareness of reducing the waste and takes action, we can contribute to our society.
