3. Acknowledge Differing Viewpoints
4. When Appropriate, Grant the Merits of Differing Viewpoints
5. Rebut Differing Viewpoints

Developing an Essay with Emphasis on Argument
Considering Purpose and Audience
Your main purpose is to convince your readers that your particular point or opinion is correct.
第二部分结束了。如果你是一路看下来的，一定已经知道这本教科书不是针对科学家写科技论文的。不过，你多多少少还是学到了一些有用的写作知识。
这本书就讲这些。是的，这本教科书的第三部分是所谓的“学术写作”。但是，不是我们写科技论文的那种写作。当然，看了没有坏处。
教科书的第四部分是“句子写作技巧指南”。学生完完全全可以自学。（不过，我不赞成这种“看错句、学英语”的方式。因为，我可能从来不会“这么错”，何苦呢？）
教科书的第五部分非常不错，是阅读。建议大家慢慢看。
有问题，请留言。
