④ Who do you think will he help?
⑤When do you suppose is he going to start?
⑥Where do you think has she gone?
（错误的原因是没有分析句子结构，全采用去掉插入语的方法来解题。）
三、成分简化法
为了快捷、正确的理解题意，去掉插入语或附加的次要信息成分，就会迅速找出答案。
例7：He felt that he, rather than Alice and Lisa, ___for the coldness that had grown between them.
A、were to blame B、was to be blamed
C、were to be blamed D、was to blame
解析：去掉rather than Alice and Lisa，便可看出本句实际上是He felt that he was to blame for the coldness…，而be to blame是固定搭配，应用主动形式。这样问题就简单了，故答案为D项。
例8：His health is .
A、as poor as, if not poorer than, his sister’s
B、as poor, if not poorer than, his sister
C、poor as his sister’s if not poor
D、as poor, if not poorer than his sister’s
解析：本题乍一看很难，其实，只要把插入语if not poorer than 去掉，原句就是His health is as poor as his sister’s.故答案为A项。
四、句式还原法
1、感叹句还原为陈述句
例9：____ what little Tom said to his mother sounded !
A、How a reasonable B、How reasonable
C、What a reasonable D、What reasonable
解析；题干为一感叹句，还原成陈述句，即What little Tom said to his mother sounded____ 。很轻易发现sound之后应接形容词作表语。故答案为B项。
2、疑问句还原为肯定句
例10：Has ___can be done ____?
A、 A、all,been done B、all that,done C、all what,been done D、all that,been done
解析：题干为疑问句，还原为肯定句，即：All that can be done has been done.that can be done是定语从句，that在定语从句中作主语，不能省略。故答案为D项。
例11：Is this factory ____you visited yesterday?
A. that B.which C.the one D.where
解析:本题的干扰项是A项，其实只要把原句还原成肯定句：This factory is the one you visited yesterday。 You visited yesterday是定语从句，引导词that在定语从句中作宾语,省略了。
3、复合句还原为简单句
例12：He suggested the problem worth paying attention at the conference.
A、to discussing B、to discuss
C、to be discussed D、to being discussed
解析：本题轻易误选D项，误把being discussed当成paying attention to的宾语。假如把此复合句还原成两个简单句，即He suggested the problem at the conference. The problem is worth paying attention to.很轻易看出空白处应填“(should) 动词原形”，而worth paying attention to是修饰宾语从句主语the problem的，是形容词短语作后置定语，故答案为C项。
4、省略句还原为完整句
例13：“What will Andrew be doing in the fall?”
“____ maths at a private boys’ school.”
A、To teach B、Teaching C、To be teaching D、Be teaching
解析：题干为省略句。根据题意，答语可补充完整为Andrew will be teaching maths at a private boys’ school。一般来说，助动词全都省略，只剩下实义动词，故答案为B项。
例14： None of us could agree on where to go on vacation, so we went to different places,____to Shanghai and to Xiamen.
A、them; me B、they; I C、they; me D、them; I
解析：本题轻易误选C项。其实，题干为省略句。根据题意，特殊是so we went to different places这一句中的主语we，答语可补充为they went to Shanghai and I went to Xiamen.。故答案为B项。
单项填空题的解题方法很多，答题时我们应留意灵活运用。值得着重一提的是，在平时的高考应试复习中，光抓解题技巧的练习是不够的，要害是具备扎实的基础知识与语言运用能力，倘若这两点都能做到，考试就会得心应手，成功也就离你不远了。
