Lunar New Year
As one of the traditional Chinese festivals, it has been enjoying great popularity in our country.
Usually, no matter how far away or how busy we are, we will try to come home for the celebration. It is our pleasure to celebrate the Spring Festival, such as setting off fireworks, putting up spring festival couplets and paying new year’s call. Of course, we also like the lion dance and dragon dance. As a junior, we can get red envelops. As long as you are outstanding, you can get much more encouragement or pocket money. During the spring festival, everyone must be all smiles to face everything. However, the most important thing is that we can get together to share feasts, which is so great to us.
In short, the Chinese New Year is a prosperous party. We should enjoy this time entertaining each other. Please open your eyes and heats and you will find happiness all over the world.

TV is a necessary part of our life, and most of us spend a lot of time enjoying a variety of TV programmes every day. What benefit does TV bring to us? Does it have any bad effect on us? And why?
One possible version
First of all, watching TV brings us a feeling of relaxation. After a busy day, people can forget the pressures and challenges of work when sitting in front of TV. In addition to this, TV is a way of helping us to know the latest news and some national policies. As is known to all, TV can also enrich our knowledge and open our views by providing some relevant information.
However, TV has a bad effect on people, too. For one thing, people waste a lot of time in it. Secondly, TV kills people’s creativity undoubtedly. While watching TV, people become receptive and unquestioning. Finally, some TV shows are harmful to children, whose mind may be filled with confusing, misleading, and violent ideas.
如今很多学生带手机上学。为此，学 校组织了一场讨论。讨论的主题是： 中学生是否有必要带手机上学。请你 根据下表提供的信息，将讨论的结果 用英语整理成文。短文的开头已给出， 不计入总词数。
多数老师认为 1.中学生年龄尚小， 还不能自控 2.用手机玩游戏，发 短信, 浪费时间 3.容易引起同学间 相互攀比（vie with …）
1.方便与家长同 学联系（keep in touch with …）
Nowadays many middle school students carry mobile phones during school hours. Is it necessary? We had a big discussion. Most students think mobile phones can help them keep in touch with their friends and family. Also carrying phones is a way to be cool.
But most teachers think differently. They say using mobile phones during school hours often causes lots of problems. Firstly, students are so young that they don’t have self-control. Secondly, they waste too much time playing games and sending text messages on the phone, which will influence their study. Thirdly, carrying phones to school may make students vie with each other.
In my opinion, students shouldn’t carry phones during school hours because it has more disadvantages than advantages. Students should learn to use mobile phones at the right time.
