7 不定式 不定式由“to+动词原形”构成,其否定形式是“not/never to do”,不定式可以带宾语或状语构成不定式短语,没有人称和数的变化,但有时态和语态的变化。不定式可以作主语、宾语、补足语、状语、表语和定语,但不能单独作谓语。不定式的逻辑主语有时用“for+名词或代词宾格”构成。

8 动词不定式的作用 Functions of Infinitive
1 主语 (subject) 2 表语 (predicative) 3 宾语 (object) 4 主|宾补 (subject|object complement) 5 定语 (attribute) 6 状语 (adverbial) 7 独立结构 (absolute construction)

9 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,不定式后置。

10 注 意 It is +adj+for sb +to do sth(如果说明不定式表示的动作的发出者的话,要在不定式的前加for引起的短语,构成“for+名词/代词宾格)+不定式。) Eg,It is easy for him to work out this math problem. It is +adj +of sb+to do sth(表示人的品行形容词;clever,kind,nice,wise,foolish,polite,stupid,silly)作表语时,不定式前常用of引起的短语。 Eg,It was foolish of him to make such a mistake. =He was foolish to make such a mistake.

11 My job to protect the world. Your task _____________. to work hard
2 不定式作表语 (predicative) My job to protect the world. Your task _____________. is to work hard is

12 × × √ √ 不定式常用在系动词 be, seem, appear, get, remain等后作表语。
Seeing is to believe. To see is believing. Seeing is believing. To see is to believe. × 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。

13 practise more 3 不定式作宾语 (object) Yao Ming likes to play basketball.
I find it still necessary (for him) to _________ if he wants to win. practise more 句型:think/ consider/ find it + adj.+ to do

14 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,etc。

15 My mum asks me to play the piano two hours every day.
4 不定式作宾补 (object complement) My mum asks me to play the piano two hours every day.

16 warn, tell, allow, help, ask, force等
引导不定式作宾补的动词: warn, tell, allow, help, ask, force等 +sb to do sth The teacher told me to clean the blackboard. I expect you to give me some help.

17 五看 三使 一感觉: watch see let look at make observe have notice + sb do sth
(不带to) listen to 二听 hear 一感觉: feel

18 但当以上的动词用于被动式,to要还原: 1. They saw the boy fall suddenly from the tree. The boy was seen to fall suddenly from the tree. Mother made John wash the car for a week. John was made to wash the car for a week.

19 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;

20 另外不定式用在介词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.

21 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.

22 不定式作定语 1. 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.

23 不定式作定语与所修饰的词之间有 三种关系: (1) 动宾关系 I have a lot of work to do. 我有很多工作要做。 He is always the first to come. 他总是第一个来。 We all have a chance to go to college. 我们都有上大学的机会。 (2)主谓关系 (3)同位关系

24 2. 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 come and the last to leave. 3. something, anything, nothing, everything等复合不定代词常用不定式做后置定语。

25 (不定式to send的动作执行者是you) 已被省略的me 或someone else)
注意比较: 1) Have you anything to send? 你有什么东西要寄吗? 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 send的动作执行者是you) (不定式to be sent的动作执行者是 已被省略的me 或someone else)

26 3. 也可用在have … to do和there be
句型中。 There is no one to take care of her. I have no jewelry to wear. 4. 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

27 I got up early to _____________. You came here to________.
6 不定式作状语 (adverbial) catch the train I got up early to _____________. You came here to________. 在一些短语中也有体现 in order to, so as to, enough to, only to, too ... to

28 不定式作状语 1. 表示目的: to in order to so as to eg: He spoke loudly (so as / in order) to be heard.

29 2. 表示原因: 不定式可以用在作表语的形容词后作状语, sorry, surprised, happy, glad, eager, angry, foolish, right, wrong, slow, quick, rude, cruel, disappointed等。 eg: I’m glad / pleased to see you. We were surprised to hear the news.

30 3. 结果状语: so + adj. / adv. + as to do… such + adj. + 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.
