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+不定式的情況下，動(dòng)詞不定式的主動(dòng)形式表示被動(dòng);這些形容詞一般為easy, hard difficult, important, interesting, heavy, pleasant, comfortable, sage等。此時(shí)動(dòng)詞不定式中的動(dòng)詞為及物動(dòng)詞。

　　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 此題考查非謂語動(dòng)詞的用法。本句為現(xiàn)在分詞短語做原因狀語，分詞的主語和句子的主語不一致，因此B為正確答案。本句的意思是：“已經(jīng)很晚了，我們決定立刻離開，因?yàn)槲覀儾幌胝`車�！边x項(xiàng)A中的as應(yīng)連接從句。

　　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。本題考查的是現(xiàn)在分詞表原因，變否定形式直接在ing之前加not。he與want 之間是主動(dòng)關(guān)系，排除B。Have no money與want沒有先后順序，所以排除不定式。本句意思是：因?yàn)闆]錢，又不認(rèn)識(shí)別人，他只說自己不吃晚飯也行。

　　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與前面的museum為被動(dòng)關(guān)系，所以用被動(dòng)形式，C和D項(xiàng)排除;由句意“據(jù)說，這座宏偉的博物館建成于大約100年前”可知，動(dòng)詞build表示的時(shí)已經(jīng)發(fā)生的動(dòng)作，故用不定式的完成被動(dòng)形式。be said to：據(jù)說……。

　　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

　　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相比較B而言，to是介詞，后面接名詞或動(dòng)名詞，所以選B項(xiàng)。

　　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。介詞后面要跟動(dòng)名詞做賓語，當(dāng)動(dòng)名詞的動(dòng)作在謂語動(dòng)詞所表示的動(dòng)作之前發(fā)生時(shí)，要用動(dòng)名詞的完成式。Thank you for having helped me so much.感謝你給了我這么多的幫助。

　　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。感官動(dòng)詞feel，hear，see，watch等后面接賓補(bǔ)的時(shí)候，要用無to不定式。但如果句子是主語的補(bǔ)足語的話，要加上to。A thief was seen to steal something from the room.一個(gè)小偷被看見從屋子里偷了東西。

　　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 從句意可知，對(duì)演講者來說重要的是“讓別人清楚地聽到自己地講話，即讓自己被聽見”;speaker作hear的邏輯賓語，所以用不定式的被動(dòng)語態(tài)形式;D項(xiàng)不是正確的表達(dá)方法。

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

　　A. to involve B. involve

　　C. involving D. involved

　　12. Tom said that he wouldn’t mind__________.

　　A. to wait for us

　　B. waiting for us

　　C. wait for us

　　13. I enjoy playing basketball and then _______.

　　A. taking a bath

　　B to take a bath

　　C. take a bath

　　D took a bath

　　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。本句是動(dòng)詞不定式的完成、被動(dòng)式。當(dāng)不定式的邏輯主語是不定式表示的動(dòng)作的對(duì)象時(shí)(或是動(dòng)作的承受者時(shí))，不定式一般要用被動(dòng)式。不定式的完成式所表示的動(dòng)作發(fā)生在謂語動(dòng)作或狀態(tài)之前。如：He is not likely to have been told the result.這個(gè)結(jié)果可能還沒有告訴他。

　　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 本題考察的是動(dòng)名詞的否定式. apologized for … 表示“為某事道歉”for是介詞，后面應(yīng)該接動(dòng)名詞(復(fù)合結(jié)構(gòu)),故排除C,D.動(dòng)名詞的否定形式是在動(dòng)名詞前加 not，故選 A. 句意是“海倫為她沒能去參加晚會(huì)而道歉.”
