可以在句子中作主语、宾语、表语、宾语补足语、定语、状语等。

1.作主语动词不定式作主语可位于句首，也可使用it作形式主语，而将其置于句末。

例如To learn a skill is very important for everyone in society.或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。

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”。

例如：It took us half an hour to ride to the town by bike.2.作表语动词不定式作表语常用于以下结构：My wish/ job/ aim/ goal is…3、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, promise, offer, afford,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。

例如：I think it necessary for us to have a good rest after the long work.She felt it her duty to help the old woman.4、作宾补可后接动词不定式作宾补的常见动词有：advise, allow, ask, hear, order, see, tell, want, wish, watch等。

例如：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)。

例如：Who made him work all night long?但是，改为被动结构后，应补出省略的to。

例如：He was seen to break the window. 5、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：6、作状语动词不定式作状语，可表示目的、原因、结果。

例如：We went there to see our grandparents.（目的）I am very sorry to hear that.（原因）She hurried home only to find her father dead.（结果）作目的状语，还可以使用in order to或so as to。

例如：The boy worked so hard in order to make up for the lost time.结果状语还可以使用enough to, too…to…, so…as to, such… as to等结构。

例如：He got up too late to miss the early bus.She was in such a hurry as not to notice me. 她如此匆忙，以致没有注意到我。

二）时间状语从句引导时间状语从句的从属连词有when（当……时），while（在……期间），as（当……，一边……一边……），before（在……之前），after（在……之后），since（从……以来whenever（无论何时），as soon as（一……就）till/until (直到……为止)，not…until (直到……才)等。

例如：When I went into the classroom, he was reading.He read a newspaper as he went along.We must strike while the iron is hot. 我们必须趁热打铁。

I will tell you after he leaves. 在他走后我再告诉你。

I waited till/until she was back. 我一直等到她回来。

Don’t get off the bus until it stops. 等车停稳后才下车。

注意：当主句为将来时态或具有将来意义时，时间状语从句通常要用一般现在时表示将来意义，而不能直接使用将来时态：三）条件状语从句引导条件状语从句的从属连词有: if(如果), unless (=if…not除非), as/so long as(只要)。
