动词不定式在句中可充当主语、表语、宾语、宾补、定语和状语等。
一、作主语
动词不定式作主语可位于句首。例如:
To learn a skill is very important for everyone in society.
也可使用it作形式主语,而将其置于句末。例如:
It is necessary for young students to learn a foreign language.
动词不定式作主语的常用句型有:
1. It is+adj./ n. (+for sb./sth.) + to do sth.
用于此句型的形容词有:easy, hard, difficult, possible, important, impossible, necessary, good, bad, exciting, interesting, surprising等。
考例1:Is ____ possible to fly to the moon in a spaceship (88 MET)
A. now B. man C. that D. it
用于此句型的名词有:pity, shame, pleasure, one’s duty, one’s job, fun, joy, good manners, bad manners等。
2. It is+adj.+of sb.+to do sth.
该句型中只能使用描述某人的品德、特征的形容词,如: kind, nice, wise, silly, polite, impolite, friendly, foolish, clever等。
3. It takes sb.+some time+to do sth.
该句型意为“做某事花费某人多长时间”。
二、作表语
动词不定式作表语常用于以下结构:My wish/ job/ aim/ goal is…及The next step/ measure is …等。
三、作宾语
常见的只能使用动词不定式作宾语的动词有:agree, choose, decide, hope, fail, wish, refuse, expect, manage, plan, intend, pretend, promise, offer, afford, demand, arrange等。
believe, think, consider, feel, make等动词可用于“动词+ it +adj. / n+to do sth.”句型,其中使用it作形式宾语,而将真正的宾语动词不定式置于句末。
四、作宾补
可后接动词不定式作宾补的动词有:advise, allow, ask, hear, order, see, tell, want, wish, watch等。believe, consider, count, declare, deny, feel, find, guess, imagine, judge, know, prove, realize, suppose, think等动词后可接to be型不定式作宾补。 hope, demand, suggest等动词不能后接动词不定式作宾补。例如:
【误】I hope my son to be back soon.
【正】I hope my son will be back soon.
【误】She suggests us to have a discussion about it.
【正】She advises us to have a discussion about it.
【正】She suggests that we (should) have a discussion about it.
在主动结构中,下列动词后作宾补的动词不定式应省略to:“五看”(see, watch, notice, observe, look at)“三使”(make, let, have)“两听”(hear, listen to)“一感觉”(feel)。
但是,改为被动结构后,应补出省略的to。
五、作定语
动词不定式作定语,应位于所修饰词语之后,即:作后置定语。例如:
Have you got anything to eat (to eat修饰anything,位于其后)
下列名词后常接动词不定式作定语:ability, attempt, chance, courage, decision, effort, failure, promise, way, wish等。由only, first, last, next以及序数词或形容词最高级修饰的名词后,也常接不定式作定语。
六、作状语 动词不定式作状语,可表示目的、原因、结果或条件。
作目的状语,还可以使用in order to或so as to。结果状语还可以使用enough to, too…to…, so…as to, such… as to等结构。
