One possible version:

We have held a discussion about whether it is good or not for a top student to share a desk with a slower student.

Some are for the idea. They believe everyone has strengths as well as weakness. Although lower students are not good at lessons, they might do well in other fields like sports or arts. Therefore, they can learn from each other, and they may develop friendship.

However, some top students don’t hold the same view. They think some slower students are always making trouble, such as keeping talking in class, breaking school rules, which has a bad effect on their studies. Besides, they may often be asked questions by slower students, which will probably distract them from their lessons.

In my point of view, that top students share desks with slower students does good to them all.

They can learn from each other and improve themselves in different fields.

题目分析：本文属于正反观点类作文，是议论文的一种，本文讨论的话题是：成绩好的学生和成绩差的坐在一起的好处有益处。要以一般现在时和第三人称为主。在叙述过去发生的事情的时候，可以使用一般过去时，在发表个人观点的时候可以使用第一人称。

要点：1.赞成的观点：人人都有长处和不足, 成绩差的学生也有可取之处;相互学习, 建立友谊.2.反对的观点：部分学习差的学生常常上课说话, 违反校规, 成绩好的学生可能会受到影响;总是问问题, 使成绩好的学生不能专心学习.3.你的观点：应该让好生和差生坐在一起，可以相互学习到对方身上的优点。

【亮点分析】本文最对连接词的使用很到位，如therefore，however，besides，In my point of view这些连接词把文章连成了一个整体。另外文章中的高级句式的运用较多，如They think some slower students are always making trouble, such as keeping talking in class, breaking school rules, which has a bad effect on their studies.这里的which引导的非限制性定语从句，which指代一句话的内容在句中做主语。
