利用固定搭配解题
完形填空题中对词汇知识的考查，主要体现在习惯用法和同义词、近义词的辨析两方面。习惯用法是英语中某种固定的结构形态，即所谓的“习语”，不能随意改动。所以，考生平时应掌握好习惯用法。对词义辨析题的考查有加大力度的趋势。要做好这类题，需要有较大的词汇量和词语搭配能力、词语辨析能力，特别是在特定的语境中能灵活运用的能力。如：
They couldn’t read or write. They didn’t like to work and they never ___12___ baths.
12. A. took B. washed C. ran D. covered
【解析】本题考查的是固定搭配take a bath，意为“洗澡”。
I did very badly at school. My headmaster thought I was useless and when I was 14 he said, “You’re never going to be ___2___ but a failure.”
2. A. anything B. something C. everything D. nothing
【解析】本题考查习语anything but，意为“决不”“根本不”，即校长认为我肯定是一个失败的人。
