　　上面两道题都是考察构词法规则,一是采用单句形式,二是采用成段形式,要求根据提供的单词转换成为同一词根的另一种词类。需要注意的是，在成段形式中，也可能有一个词不必改变其词类。要想做好这两道题，教材中有关构词法的知识至关重要。对于成段形式的词类转换，我们建议先快速游览一遍整段内容，抓住整段内容有助于确定个别单词的正确形式。

　　（四）在下列单词中选择正确的词填空，每词限用一次。

　　这种完形填空是考察学生对语法和词汇的运用以及简单的阅读理解能力。试题的短文中有10个空格，要求考生从所提供的12-15个词中选择正确答案，填入空格中。本题的短文选自教材以外的文章。我们建议做这道题时，还是先快速浏览一遍全文，以求获得整体印象，然后再选择正确答案。此外，应该采取“优选法”，有把握的词先填入适当的位置，这样剩下不多的词就比较易“择优选择”了。
