一、插入语干扰
1. He believes in himself, _________, in my opinion, is of great importance.
A. that B. which C. what D. as
2. He hasn't come yet. What do you consider_________to him?
A. happens B. has happened C. happening D. to happen
3. John plays football _________, if not better than， David.
A. as well B. as well as C. so well D. so well as
4. The manager decided to give the job to_________he believed had a strong sense of duty.
A. whoever B. whomever C. who D. those
[析]这类题主要是利用插入语，增加句子的复杂程度，从而达到干扰学生视线的目的。我们只要去掉冗余信息(插入语)，答案就一目了然了。
二、标点符号干扰
5. Tom，_________sure to come tomorrow.
A. is B. be C. was D. would be
[析] 很明显，Tom在这里并不是句子的主语，而是称呼语。
三、疑问句干扰
命题人利用一般疑问句和特殊疑问句的特殊结构，达到干扰目的。解题时，只要把句子还原为陈述句，就可以看清它的庐山真面目了。如:
6. Who would you rather_________with you tomorrow， Tom or Smith?
A. have to go B. have go C. have gone D. had go
[析]我们可以把它变为陈述句:I would rather have Tom go with me tomorrow. 原来是把句子的宾语提前到了句首，go是省去了to的不定式作宾语补足语。
四、倒装句干扰
7. On the grass_________two sheep.
A. lies B. lie C. lying D. laid
[析]这个句子的语是two sheep而非grass，故选用复数谓语动词。
五、从句和先行词分离干扰
同位语和定语从句一般情况下是紧跟在先行词之后，但有时为了句子平衡的需要，先行词和从句分开，从而造成了干扰。如:
8. The question came up at the meeting _________ we had enough money for our research.
A. that B. which C. whether D. if
[析]后面的句子是一个同位语从句，而它的先行词是句首的question.
六、省略句干扰
9. The girl is very shy， and never speaks until_________to.
A. spoken B. speaking C. speak D. be spoken
[析]这个句子从句省去了相同的主语she和be动词，可以恢复为:The girl is very shy， and never speaks until she is spoken to.
10. If you don't go there，_________I.
A. neither do B. nor will C. so do D. neither did
[析]此句尽管条件状语从句用的是一般现在时态，但并不一定表示现在的动作。从句子意义来判断，动作发生的时间应该在将来，很显然，它省去了一个将来时间状语。
七、被动句干扰
11. Every minute is made full use of_________at our lessons.
A. to work B. working C. having worked D. being worked
[析]有些同学一见到介词，后面马上用名词或动名词。这恰恰落入了命题人设置的陷阱。此题of的宾语实际上是every minute.如果把它变为主动式，答案就显而易见了。即:We make full use of every minute to work at our lessons.
八、搭配干扰
有时，出题人故意造成是某种固定搭配的假象，似是而非，极易上当。
12. This is the very room_________I slept in that evening.
A. that B. which C. where D. at which
[析]时间状语that evening前面不必加介词in，故这个定语从句应用关系代词引导，考虑到先行词被very修饰，故用that引导定语从句。试比较:
This is the very room where I slept in the evening.
13. The country life he was used to_________greatly since the opening policy.
A. change B. has changed C. changing D. having changed
[析]he was used to在句中作定语从句，修饰life.分析句子结构，整个句子缺少谓语动词，故填入主句谓语。
九、定语从句干扰
14. The young student did all that he could_________the examinations.
A. pass B. to pass C. passing D. passed
[析]that he could (do) 是定语从句，修饰all.to pass the examinations在句子中作目的状语。
15. Mrs. Brown was much disappointed to see the washing machine she had had_________went wrong again.
A. it B. it repaired C. repaired D. to be repaired
[析]这道题考查了两个知识点，一是考查了have sth. done结构，二是定语从句。she had had repaired(had的宾语which在定语从句中提前，且省略了)是定语从句，修饰the washing machine.此句可译为:"布朗夫人很失望地发现她刚刚请人修理好的洗衣机又出了毛病。"
十、非正常语序干扰
16. The home improvements have taken what little there is_________my spare time.
A. from B. in C. of D. at
[析]为了保持句子平衡，该句采用了非正常语序。该句的正常语序是:The home improvements have taken what little of my spare time there is. 本句意为"改善家庭居住条件占去了我仅有的一点业余时间。"there is是定语从句，用来修饰前面的名词短语what little of my spare time.
十一、强调句干扰
17. It is the protection for the trees_________really matters， rather than how many trees are planted.
A. what B. that C. / D. which
[析]此句是强调句，强调主语。可还原为:The protection for the trees really matters， rather than how many trees are planted.
十二、词形变化干扰
18. -I like football.
-_________my sister and me.
A. So do B. So are C. So did D. So it is with
[析]如不仔细观察，学生很可能选择A.应该要注意这里的me.我们知道so does sb. 句式是一个倒装句，即sb. 是句子的主语，要求用主格。
十三、多义词干扰
试比较下列两个例句:
19. He is a strange character，_________is very hard to get along with.
A. who B. which C. that D. where
20. He has a strange character，_________makes him difficult to get along with.
A. who B. which C. that D. where
[析]多义词character在两个例句中有不同的含义。在例1中，character表示"人物"，例2中，character表示"性格".
