2. 误点点拨：①改为it’s convenient for them, convenient的主语不可为人。
②them改为themselves。
③改为for example。注意后面应加上逗号，such as后面不能接句子。
画龙点睛：文章的第一段由于数据的堆砌使得句式单调，如40% have QQs.可改为the rate doubled。可将In 2006, about 50% of them owned QQs, and in 2007, 60% of them had QQs. 整合为一句，Likewise, it rose from about 50% in 2006 to 60% in 2007. 这样修改使句子更加简洁，避免了重复。
[范文]
As is shown in the chart, the rate of students who owned QQs increased in the past four years from 2004 to 2007. Back in 2004, only 20% of them have QQs; one year later, the rate becomes twice larger; compared with about 50% in 2006, the rate in 2007 rose to 60%. Clearly, it is tending to increase.
In my opinion, the increase can be accounted for two factors. For one thing, the widespread use of the Internet makes it convenient for students to communicate with each other. For another, QQ provides all kinds of entertainments, such as playing games and enjoying music. What’s more, QQ has gradually become the main means for the public to know the latest news. Personally, students should make proper use of and not be addicted to QQ, and only so can it serve its purpose beautifully.

1. 总体评价：本文是一篇叙议结合的短文，要点基本齐全。作者首先简要描述了变化，并在第二段就QQ流行的原因做了说明，最后提出建议。此外，本文作者合理使用了一些关联词和过度词语，使文章前后连贯，内容紧凑，过渡自然，提高了文章的得分档次。但是由于第一段过于单调，减去2分，加上出现一些明显的词语用法错误，使得文章失分不少。
