1. One of the benefits of the new model is that it is easier____ than the old one.

　　A. operating

　　B. to be operated

　　C. to operate

　　D. operated

　　【答案】C 在有些be+adj+不定式的情况下，动词不定式的主动形式表示被动;这些形容词一般为easy, hard difficult, important, interesting, heavy, pleasant, comfortable, sage等。此时动词不定式中的动词为及物动词。

　　2. _____, we decided to leave at once, as we didn’t want to risk missing the bus.

　　A. As it being pretty late

　　B. It being pretty late

　　C. It was being pretty late

　　D. Being pretty late

　　【答案】B 此题考查非谓语动词的用法。本句为现在分词短语做原因状语，分词的主语和句子的主语不一致，因此B为正确答案。本句的意思是：“已经很晚了，我们决定立刻离开，因为我们不想误车。”选项A中的as应连接从句。

　　3. Having no money but ____ to know, he simply said he would go without dinner.

　　A. not to want anyone

　　B. wanted no one

　　C. not wanting anyone

　　D. to want no one

　　【答案】C。本题考查的是现在分词表原因，变否定形式直接在ing之前加not。he与want 之间是主动关系，排除B。Have no money与want没有先后顺序，所以排除不定式。本句意思是：因为没钱，又不认识别人，他只说自己不吃晚饭也行。

　　4. The magnificent museum is said ___ about a hundred years ago.

　　A. to be built

　　B. to have been built

　　C. to have built

　　D. to have being built

　　【答案】B。build与前面的museum为被动关系，所以用被动形式，C和D项排除;由句意“据说，这座宏伟的博物馆建成于大约100年前”可知，动词build表示的时已经发生的动作，故用不定式的完成被动形式。be said to：据说……。

　　5. We hurried to the station ______ find ourselves three hours earlier for the train.

　　A. only to

　　B. in order to

　　C. so as to

　　D. such as to

　　【答案】A 这句话的意思是我们赶到车站发现我们早到了三个小时，in order to 和so as to都表示为了，such as to不符合语法规范，B, C, D都可以排除。

　　6 “Do you like to ride on the old bus to school?” “Yes, I prefer it ___.”

　　A. to walk

　　B. to walking

　　C. walking

　　D. having walked

　　【答案】B。prefer A to B：更愿意做A相比较B而言，to是介词，后面接名词或动名词，所以选B项。

　　7. I am very sorry for ___ for so long.

　　A. keep you waiting

　　B. having kept you waiting

　　C. waiting for you

　　D. keep you wait

　　【答案】B。介词后面要跟动名词做宾语，当动名词的动作在谓语动词所表示的动作之前发生时，要用动名词的完成式。Thank you for having helped me so much.感谢你给了我这么多的帮助。

　　8. The middle-aged man was seen ___ out of the house on the afternoon of the murder.

　　A. came B. come

　　C. to come D. have come

　　【答案】C。感官动词feel，hear，see，watch等后面接宾补的时候，要用无to不定式。但如果句子是主语的补足语的话，要加上to。A thief was seen to steal something from the room.一个小偷被看见从屋子里偷了东西。

　　9. The ability ___ is very important for any speaker.

　　A. to hear clearly

　　B. to be clearly heard

　　C. to hearing clearly

　　D. to being clearly heard

　　【答案】B 从句意可知，对演讲者来说重要的是“让别人清楚地听到自己地讲话，即让自己被听见”;speaker作hear的逻辑宾语，所以用不定式的被动语态形式;D项不是正确的表达方法。

　　10. You ought to know better than ____ yourself in unnecessary expense.

　　A. to involve B. involve

　　C. involving D. involved

　　【答案】A 本题考察的是固定搭配. know better than to do sth. “不至于蠢到” 句意是“你应该不至于蠢到使自己陷入不必要的损失里吧!”

　　12. Tom said that he wouldn’t mind__________.

　　A. to wait for us

　　B. waiting for us

　　C. wait for us

　　D. for waiting us

　　【答案】B mind作介意讲后面接动名词,排除A,C.但mind是及物动词,不用介词,故排除D.答案选B.句意是“汤姆说他不介意等我.”

　　13. I enjoy playing basketball and then _______.

　　A. taking a bath

　　B to take a bath

　　C. take a bath

　　D took a bath

　　【答案】A 由and连接的并列句,前后应保持一致,enjoy的宾语用的是动名词形式,同样and 后的宾语也要用动名词形式.故选A. 句意是“我喜欢打篮球,然后洗个澡.”

　　14. The famous novel is said ___ into Chinese.

　　A. to have translated

　　B. to be translate

　　C. to have been translated

　　D. to translate

　　【答案】C。本句是动词不定式的完成、被动式。当不定式的逻辑主语是不定式表示的动作的对象时(或是动作的承受者时)，不定式一般要用被动式。不定式的完成式所表示的动作发生在谓语动作或状态之前。如：He is not likely to have been told the result.这个结果可能还没有告诉他。

　　15. Helen apologized for ____ to attend the party.

　　A. her not being able

　　B. her being not able

　　C. her to be not able

　　D. her not to be able

　　【答案】A 本题考察的是动名词的否定式. apologized for … 表示“为某事道歉”for是介词，后面应该接动名词(复合结构),故排除C,D.动名词的否定形式是在动名词前加 not，故选 A. 句意是“海伦为她没能去参加晚会而道歉.”
