1. To tell you the truth, I am not in favour of your plan.
答案：To tell you the truth
此处是状语性的插入语,相当于于汉语的“说实话吧、老实讲”,本意可以理解为“为了告诉你实话”,阐述的是目的.
A 项 Telling you the truth 是分词短语,在句首一般用作时间或原因状语；
B 项 To tell you the truth 是不定式短语,用作目的状语,加之告知的是后面提到的 I am not in favour of your plan 所以 truth属于特指,必须用定冠词,此项是正确答案；
C 项介词短语 For telling you the truth 虽然也可以用作目的状语,但是与 B 项不同的是前者不定式表示未来.指的是其后提到的事实,而后者介词加动名词则表示发生过的行为,即“为了已经说过的实话”,与题意不符；
D 项中 To tell you a truth 的不定冠词是错误的.
2. They exchanged views on the question of ___
答案选 B whom to be elected
该题是考查动词 elect 和 whom 的逻辑关系,显然它们是动宾关系,即 whom 是被选的,而不定式的被动形式表示将要被选的,另外连接代词 whom （兼作逻辑宾语）必须放在整个短语的首位.
3. They were made __like a dog.
答案：B to work
该题是被动语态,是由主动语态 XX made them work 变来的,them 是宾语,work 是不带 to 的不定式补足语,但是句子变为被动以后,原来的宾语改为主语,不定式就成了主语补足语,这种补足语的 to 的是不能省略的.
4 This machine isn't very complicated. All you have to do is ___and it starts.
答案：D to pull the switches.
不定式表示将要做的事情就是要这些电闸或开关拉开.
A. to put these switches away 意思是“要把这些开关/电闸放在一边”
B. putting these switches away 意思是“总把这些开关/电闸放在一边”
C. to pull yourself together 意思是“集中自己的全部力量”
5. Did he miss his stop? The bus was so crowed that he had a hard time ___
答案：B. getting off
短语have time doing sth. 表示做某事用去很长时间,也可以用 spend time doing sth. 这里的分词短语伴随方式状语.
6. How did you learn to speak English so fluently? ___whenever I had a chance .
答案： D. By practicing speaking
回答是个省略句,说完整了就是：I learned to speak English so fluently by practicing speaking whenever I had a chance. 介词短语by doing sth. 表示借助做某事的方法.
7. Has the question been settled? No it is ____
答案：D far from being settled
选项分析：
A far from to be settled：介词后一般不能用不定式
B. not yet to be settled：不定式表示未来被解决,而 not yet 则是至今还没有,前后矛盾.
C. going to settle it：代词 it 指代question,不具备行为能力,即使不考虑 it的重复问题,它也不能去解决问题,如果改为 it is going to be settled 则可用
D. far from being settled: 意思是“离被解决还很远”,介词 from 后跟动名词短语符合语法结构.
8. ____form the hill, the village looks magnificent.
答案：D Seen
句首的分词用作时间或原因状语,不定式只表示目的,本句中表示的就是时间,即“当从山上看那个村庄的时候”；分词的逻辑主语是句子的主语,现在分词 seeing 与 the village 是主谓关系,即“村庄从山上看”,这显然是荒谬的；而过去分词 seen 则与 the village 是动宾关系,即“村庄从山上被看”,是符合逻辑关系的.
