为了培养同学们的发现问题，分析问题，和解决问题的能力，命题人也常常出一些通过排除从而推知未知的东西的试题，而这我们要用排除法。
所谓排除法就是根据题目的要求，结合所学知识，排除题干中的冗余信息或者四个选项中的错误选项，从而降低理解难度，缩小选择范围，快速明确答案，提高命中率。具体来说有以下几点：
一、排除题干中的冗余信息
这些冗余信息包括插入语、定语从句、伴随状语等：
1. John plays football ___, if not better than, David.
A. as well B. as well as C. so well D. so well as
解析：若能排除题干中的插入语。If not better than 此题难度则大大降低，该题考查副词的比较等级的用法，as well as 这里意为“和......一样好”。答案是B。
2. Is this the girl ___you think is kind and honest?
A. which B. who C. whom D. of whom
解析：若能排除题干中的插入语you think，便会发现定语从句缺少主语。而且指人，应用关系代词who，因此答案为B。
3. Hardly had all the points that the teacher taught ____down when the bell rang.
A. to taken B. taking C. taken D. been taken
解析：此题句子结构复杂，难度颇大，里边包含hardly…when句型，表示“一......就......”。若能识别出定语从句that the teacher taught ，则会发现其余部分是被动语态。“知识点被摘抄下来”，答案为D。该句意为：我刚抄写完老师教的知识点就下课了。
4. Mr. Green together with his wife and children ___to Egypt by air for the ten –day holiday.
A. go B. have gone C. is going D. are going
解析：题干中together with his wife and children 是伴随状语而不是并列主语。这样主语只有Mr. Green，据此判断谓语动词应用单数形式，只有C项符合乎要求。因此答案是C。
5. We didn’t plan our art exhibition like that but it ____very well.
A. worked out B. tired out C. went on D. carried on
解析：本题中的tired out 是“精疲力竭”；went on 是“继续进行”；carried on是“进行下去”。通过上文“并没计划着象那样”，说明这一活动已结束，而从上面已知的B/C/D都无法表达这一语义，我们熟知work out 有“算出、解决”的意思，进一步延伸就是“结果”，所以选A。
6. It’s generally believed that teaching is ___it is a science.
A. an art much as B. much an art as
C. as an art much as D. as much an art as
解析：本题考查的是as…as 结构中的语序，所以A.B都不合适。因为第一个as 是副词，所以它不能直接修饰名词结构，它要求把这一结构中的形容词提到冠词之前，故本题选D。 即使选出之后，我们对这一陌生结构仍然糊里糊涂="Times New Roman">
评注：为了培养学生们的探索精神，以及在阅读中面对未知单词有良好的心理素质，命题人有意设计一个我们十分陌生的表达方式。我们可以依据我们所知道的、熟知的条件把它放在新的语境中，如果都不合适，那麽不熟悉的就可能是我们要选择的。
二、排除选项中的错误选项
1．Little Jim should love ____to the theatre this evening.
A. to be taken B. to take
C. being taken D. taking
解析：首先根据句意，“小吉姆是被带到剧院”，应用被动结构，故排除B、D，其次should love to do相当于would like to do，表示“想做某事”，后接不定式短语，可排除C，故答案是A.
2. My dictionary ___. I have looked for it every where but still ____it.
A. has lost; don’t find B. is missing; don’t find
C. has lost; haven’t found D. is missing; haven’t found
解析：首先根据句意“我的字典丢了”，我到处找但是还没有找到，物品丢失可以说be lost , be missing ; be gone ， 据此排除A/C，其次，这是一个并列句，前后时态应一致，用现在完成时表示过去发生的动作对现在造成的影响；没有找到字典，因此排除B，答案是D。
3. ____, Mother will wait for him to have dinner together.
A. However late is he B. However he is late
C. However is he late D. However late he is
解析：首先however 引导的状语从句应用陈述语序，排除A/C；其次，在该状语从句中，however后边要紧接一个形容词或副词，排除B，故答案是D。
