On-line friend(s)

Recently ,people have had a heated discussion about whether students should make friends on-line. Different people hold different opinions.

Some of them agree with the opinion . The reasons are as follows: first, we can make more friends with others on the Internet. Second, We can express our ideas freely. Besides, making friends on line can contribute to learning English.

However, others are against the opinion .The reason why they disagree is that they think it is a waste of time to make friends on line and has a bad effect on study. What’s more, students are likely to be cheated on line .

Each coin has its two sides .In my opinion, making friends on line is good for us because it is very convenient and can widen our horizon.

All the best ,

Yours，

题目分析：这是一篇议论文，第一段赞同学生网上交友的人的观点，第二段是反对学生网上交友观点，第三段是表述作者自己的观点。第一段陈述赞同的理由时作者用了Firstly, Secondly, they can express their feelings Besides,来连接，是文章有层次，并且很流畅。第二段是反对的人的观点和他们的理由，作者没有重复第二段的方法而是用了 in addition来过渡。第三段是作者自己的观点，范文中用In my opinion/ From my point of view来表达自己的观点，观点明确，还有自己的令人信服的理由。一篇好的作文要做到：要点要全，表达要清晰明确，使用短语，句型要准确，注意避免拼写和语法错误，熟练运用好的词组。例如as follows、 a waste of time get cheated、 As for friendship 和widens our eyes and enriches our knowledge.都用了我们学过的重点短语，另外这篇文章里的好句型也是亮点，例如：chatting on line is also helpful for our language study. /They say making friends on line is a waste of time, which should be spent more meaningfully/ Only in this way can making online friends be valuable to us.熟练正确的使用这些句型能体现考生的水平，也会给自己的文章加分。

点评：这类作文的写作方法要注意认真审题，可以分三段写：赞成；反对；你的看法。注意过渡性语言的使用。做到：要点要全，表达要清晰明确，使用短语，句型要准确，注意避免拼写和语法错误，熟练运用好的词组。
