1 不定式作主语 (subject) To keep smiling is healthy for you. It’s important to look up the new words in the dictionary when you study English. 单个不定式作主语时, 谓语动词用单数。若不定式太长, 往往用it作形式主语 句型：It ＋be＋adj. for/of sb to do sth.

It takes sb some time to do sth. 2 不定式作表语 (predicative) To see is to believe. /Seeing is believing. 不定式常用在系动词 be, seem, appear, get, remain等后作表语。 All you have to do is (to) finish the job quickly. 如果主语部分有个表示不定式内容的do, 用作表语的不定式可省略to。 3 不定式作宾语 (object) 句型: think / consider / find it + adj. + to do

常接动词不定式作宾语的动词有： agree, afford, appear, ask, attempt, care, choose, claim, dare, decide, demand, deserve, determine, expect, fail, get, hate, hesitate, hope, hurry, intend, learn, manage, offer, plan, prepare, pretend, promise, refuse, seem, tend, threaten, want, wish。 4 不定式作宾补 (object plement) My mum asks me to play the piano two hours every day. The teacher told me to clean the blackboard. I expect you to give me some help. 引导不定式作宾补的动词： warn, tell, allow, help, ask, force等+ sb. to do sth. 不定式做宾补时不带to的情况: 1 不定式在感官动词(feel, hear, listen to, watch, look at, notice, observe)后； 2 使役动词 (let, have, make)后边作宾补时, 省去to, 但是在被动语态中要还原to； 3 不定式用在介词but, except, besides后时, 如果这些介词前有行为动词do的各种形式, 那么介词后的不定式不带to,相反则带to。 1. She could do nothing but cry.

2. I have no choice but to go. 3. What do you like to do besides sleep. 5 不定式作定语 (attribute)

1. Kate is looking for a suitable coat to wear. 2. Tom has a nice pen to write with. ★不定式做定语时常放在被修饰的名词或代词之后 (a) She was very busy and had no time to visit her friends. (b) Ladies and gentlemen, I have something important to tell you. ★不定式作定语与所修饰的词之间有三种关系： I have a lot of work to do. 我有很多工作要做。 (1) 动宾关系 He is always the first to e. 他总是第一个来。 (2)主谓关系 We all have a chance to go to college. 我们都有上大学的机会。 (3)同位关系 ★当名词被the first, the last, the only等词以及形容词最高级修饰时 eg: She is always the first to e and the last to leave.

★ something, anything, nothing, everything等复合不定代词常用不定式做后置定语。注意比较： 1) Have you anything to send? 你有什么东西要寄吗？（不定式to send的动作执行者是you） 2) Have you anything to be sent? 你有什么要（我或别人）寄的东西吗？（不定式to be sent的动作执行者是已被省略的me或someone else）

★ 如果不定式是不及物动词, 则后面需适当的介词。 Please pass me some paper to write on.. 6 不定式作状语 (adverbial)

1. 表示目的: to ,in order to, so as to 2. 表示原因: 不定式可以用在作表语的形容词 sorry, surprised, happy, glad, eager, angry, foolish, right, wrong, slow, quick, rude, cruel, disappointed等后作状语。 eg: I’m glad / pleased to see you. We were surprised to hear the news. 3. 结果状语: Only to do

so + adj. / adv. + as to do … /such + n. + as to do …

adj. / adv. + enough + to do

too + adv. / adj. + to do

He was so foolish as to believe it. = He was such a fool as to believe it. = He was foolish enough to believe it. 7 独立结构 (absolute construction)
