第4讲　议论文
议论文是高考完形填空较难的一种文体，一般由三个要素组成：论点、论据、结论。论点和论据形成一体，相互印证。有时作者为了使文章脉络清楚，行文流畅，会使用一些连接词，如：on the contrary，all in all，in short，generally speaking，worse still，on the other hand，in conclusion，as a consequence等。做题时要注意以下几点：

内容解读
首句制胜，论点明确
议论文类完形填空的首句常常是文章的主旨句。作者一般在文章的首段提出论点，然后在各段的首句提出分论点。
不同的论点提出方式
①开门见山地提出论点，然后再通过具体的论据去说明论点，论据有时候既有正面的论据，也有反面的论据，最后总结全文。②导入式提出论点。先通过叙述生活中的一件具体的事情或描述生活中的现象，然后根据事情或现象所反映的问题提出自己的论点，再用具体的论据去说明自己的论点。③最后提出论点。有些议论文作者一开始仅仅是列举生活中的现象，不表明自己的观点，而是通过对具体现象的分析，最后得出一种结论。

尾段通常照应论点
