动词不定式精准训练
一、单选题
1. It's important ________ you ________ walk after supper．
A. of; to B. for; of C. to; to D. for; to
1. 【解析】 D 本题考查的是it + be + adj. + for / of sb to do sth 做某事对某人来说是……。介词for的选择取决于前面的形容词，描述的是后面的事情；介词of的选角取决于前面的形容词描述的是人的品质。根据句意：饭后散步时很重要的，important描述的是事情，故选介词for。
2. It's very kind ________ you ________ help me.
A. to; of B. of; to C. for; to D. to; to
2. B 【解析】本题考查的是it + be + adj. + for / of sb to do sth 做某事对某人来说是……。介词for的选择取决于前面的形容词，描述的是后面的事情；介词of的选角取决于前面的形
容词描述的是人的品质。本题中的形容词kind修饰的是人，故选B。
3. It always takes me 20 minutes ______to school.
A. go B. going C. to go D. went
4. It is our duty _______ our environment.
A. to protect B. protected C. protecting D. protect
4. A 【解析】本题考查的是it + be + n. + to do sth的固定句型，it作形式主语，真正的主语是后面的动词不定式，故选A。
5. I always tell my students ____ on the road because it’s really dangerous.
A. not to play B. to play not C. not playing D. not play
6. —I didn’t hear you come in just now. — That’s good. We tried _____ any noise, for you were sleeping.
A. not make B. not to make C. to make D. making
6. B 【解析】非谓语动词。试题解析：try to do sth:努力/尽力做某事.try not to do sth:尽力不要做某事。句意指尽量不去制造任何噪音。故选B。
7. I find ______ important _______ English.
A. it; to learn B. that; to learn C. it; learning D. that; learning
7. A 【解析】考查it作形式宾语：主语+ find / think/ feel / make / consider… it + adj. / n. + to do sth结构，故选A。
8. The pressure_____causes Americans to be energetic, but it also puts them under a
constant emotional strain.
A. to compete B. competing C. to be competed D. having competed
8. A 【解析】本句的意思是，“竞争的压力使美国人精力充沛，但也使他们的精神始终处于紧张状态。”名词pressure后应加不定式做定语，说明pressure的内容。因此本题答案是A。选项B是现在分词；D现在分词的完成式，都不符合语法规定。选项C中的compete是不及物动词，不能用被动语态，所以这三个选项都不正确。
9. Could you find someone________？
A. for me to play tennis with B. for me to play tennis
C. play tennis with D. playing tennis
miss a fei9. A 【解析】本句的意思是，“请你个人来和我打网球。”
10.Because air pollution has been greatly reduced, this city is still a good
place_________.
A. to live B. for living in
C. to be lived in D. to live in
10. D 【解析】本句的意思是，“因为污染大大减少了，这座城市是一个居住的好地方。”不定式to live in和前面的修饰语a good place形成了动宾关系，文中虽然没有出现to live in的逻辑主语，但是却隐含着 for us的意思，因此不定式应当使用主动形式。
11. With a lot of difficult problems ___________ , the newly-elected president is having a
hard time.
A. settled B. settling C. to settle D. being settled
11. C 【解析】本句的意思是，“由于有几次会议要参加，所以他不能和我们一起去长城了。”

14. —Mum. Why do you always make me eat an egg every day?
—_______ enough protein and nutrition as you are growing up.
A. Get B. Getting C. To get D. To be
14.C 【解析】本题考查非谓语动词作状语。分词作状语可以表示时间、原因、条件、伴随
情况；不定式作状语多表示目的和结果。问句以why 开头，暗示了要用非谓语动词作目的状语。作目的状语的不定式可用in order to 来引起；有时为了强调，也常常放在句首。答案为C。
15. The American troops tried many times to break into the mosque, ____
each time.
A. beaten back B. only to be beaten back
C. being beaten back D. having been beaten back
15.B 【解析】本题考查动词不定式作结果状语。A项为过去分词，其基本属性是表示“一个早于谓语动词而发生的被动动作”，通常说明谓语动词发生背景；C项为现在分词的被动体，其基本属性是表示“一个和谓语动词同时发生的被动动作”，但这种形式一般不用于作状语；D项为分词完成体的被动形式，用以强调该被动动作在位于发生之前已经完成。答案为B。
