在有些情况下，考生如果不能很有把握地直接得出某一道题的答案，可以把排除法和词汇、语法分析结合起来运用，缩小选择的范围，提高正确率。如：
The woman looked carefully at me ____ through her glasses, and then questioned me in a low voice.
A. as usualB. for a whileC. in a minuteD. once again
答案B. 这篇文章讲述的是没有工作经验的作者找到工作的故事。此题的解题关键词是carefully，既然是“认真地看”，就不会是in a minute (立刻、马上)；既然互不相识，作者也未曾去找过工作，不会是as usual(像往常一样)；前面没说已经打量过作者一次了，所以用once again(再一次)是不合理的。
He put the books into the return box. And after a brief ____ in the toilet, he would be on his way to the playground to meet Eric.
A. restB. breakC. walkD. stop
此题答案为D。人不可能在厕所里休息（rest, break）或是散步（walk），由此排除另外三个选项。
When I started playing ____ him, he told me I needed to relax because I looked nervous.
A. atB. by C. for D. around
此题用排除法，by 和around都有“在……旁边”的意思，要选都要选，故排除这两个答案，play at后接游戏名，是“做……游戏”的意思，也可排除。故答案为C。
