Consider. Feel. Find. Know. Make . regard例: we think it important to obey the laws. √ we think to obey the laws is important. ×I know it impossible to finish so much homework in a day.不定式作介词宾语当介词but、except、besides前面有行为动词do及其各种形式时,介词后面的不定式可以省略to,否则不省略。

动词不定式 讲解、专项练习及答案
初中英语语法(动词不定式)1.不定式的基本形式与结构动词不定式指通常由to加上动词原形(如to write) 所构成的一种非限定性动词形式,但在有些情况下to可以省略。
动词不定式有进行体和完成体(如上to be writing,to have written),也有被动态(如to be written),所有的主动词,不论是及物动词还是不及物动词,也不论是动作动词还是状态动词,都有不定式形式。
助动词除be和have外,没有不定式形式。
动词不定式在语法功能上可作主语、宾语、表语、定语和状语。
2.不定式的用法1)不定式结构作主语1.Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago.2.To finish that task in such a short time is really a challenge.在上述情况下,如果不定式较长,显得头重脚轻,则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替),而将不定式放到后面。
如:1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago.2.John admitted that it is always difficult for him to be on time.不定式结构所表示的动作是谁做的,即不定式的逻辑主语,通常可以通过for sb. to do sth. 结构表达:1.It is quite important for us to read good books during a general review.2.It is not difficult fot those talented students to pass the exam.在某些形容词(如careless,clever,considerate,foolish,good,impolite,kind,naughty,nice,silly,stupid等)作表语时,不定式后可以加of来引导出其逻辑主语:1.It is very kind of you to tell me the truth.2.It is stupid of him to do such a silly thing.2)不定式作宾语不定式作宾语有两种:一种是及物动词后直接跟带to的不定式,另一种是“及物动词+疑问词+带to的不定式。

不定式作动词宾语He decided to invite all of his classmates to attend the holiday at the beach. 不定式作宾语He promised not to tell anyone about it.如果宾语有自己的补语,则常用it作形式宾语,而把真正作宾语的不定式放在后面放在后面,常带有形式宾语的动词有:believe. Consider. Feel. Find. Know. Make . regard例: we think it important to obey the laws. √ we think to obey the laws is important. ×I know it impossible to finish so much homework in a day.不定式作介词宾语当介词but、except、besides前面有行为动词do及其各种形式时,介词后面的不定式可以省略to,否则不省略。
What do you like to do besides play football? We have no choice but to wait.个别介词可以用“疑问词+不定式”作宾语The boy has him own idea of how to finish it.不定式起形容词作用作定语不定式作定语用来修饰名词或代词,置于它所修饰的词后,而且放在其他后置定语的后面。
同时与它所修饰的名词或代词形成逻辑上的动宾关系或主谓关系。
He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系The next train to arrive was from Seattle. To arrive 和train形成主谓关系Do you have anything interesting to read?如果作定语用的不定式是不及物动词,就要加上介词,使被修饰的这个词成为这个介词的逻辑宾语。
He is looking for a room to live in. to live in a room. A room 是介词in的宾语。
Please pass me some paper to write on.上述不定式后加介词时,一般不能省略介词,但当修饰place,time,way时,介词可以省略。
He has no money and no place to live (in). The time to arrive is 8 o’clock. (at)I think the best way to travel is on foot.不定式作定语时,用主动语态表示被动含义的情形一、在某些固定句型中, 动词不定式作定语, 用主动形式表被动意义。
1)have(give, show)sth. to do在这种句型中的不定式与前边的名词有动宾关系, 又和句中另一名词或代词构成主谓关系。
例如: I have a lot of things to do this afternoon. to do与things是动宾关系, 与I是主谓关系。
否则, 在表示被动意义时, 仍需要被动式。
试比较:Have you anything to do this afternoon? 今天下午你有事要做吗?(to do是由you发出的)Have you anything to be taken to your parents? 你有要带给你父母的东西吗? (谁带不得而知)再如: Please get me something to read. 请给我弄点读的材料。
He'll show you the right path to take.2)It(This, That)+be+a/an+adj. + n. +to do在这种句型中, 不定式与前面的名词有动宾关系。
动词不定式可改为动词不定式复合结构。
例如: This is a difficult question to answer. 这是个难答的问题。
question与to answer为动宾关系。
to answer 可改为 for me to answer。
再如: It is an easy sentence to translate. 这个句子很容易翻译。
3)There +be +n. +to do在此句型中, 用来修饰主语的不定式, 可用主动式, 也可用被动式, 只是侧重点不同。
用主动式作定语, 重点在人, 用被动式作定语, 重点在物。
例如:没有时间可以耽误。
可译成:There is no time to lose(to be lost). 用 to lose可看成for us to lose; 用to be lost, 谁 lost time不明确。
但下述两句用主动不定式与被动不定式意义不同:a. There is nothing to do now. (=We have nothing to do now. )现在没事干。
b. There is nothing to be done. (=We can do nothing now. )现在没办法了。
a. There is nothing to see. (nothing worth seeing)没有东西值得看。
b. There is nothing to be seen. (nothing there at all)看不见什么东西。
二、在某些“形容词+不定式”的结构中, 不定式有被动意义, 与句子主语构成动宾关系。
其句型有: 1)n. +be+adj. +to doThe question was very difficult to answer. 这问题很难回答。
The job is very easy to do. 这工作很容易做。
2)n. +be+too+adj. +to doThe thing is too small to see. 这东西太小看不见。
I was too excited to say a word. 我激动得连一句话也说不出。
3)n. +be +adj. +enough to doThe box is light enough to carry. 这盒子轻得可带走。
The book is cheap enough to buy. 这本书很便宜可以买。
但下列两句可用不定式的主动式, 也可用被动式:This plant is fit to eat /to be eaten. 这种植物可以食用。
The cake is ready to eat /to be eaten. 这块饼可以吃了。
三、某些动词, 如to let, to blame (责备), to seek(寻找)用主动式表被动意义。
例如: The house is to let. 这房子要出租。
Who is to blame for it? The reason is not far to seek. 这理由不难找到。
不定式的省略不带to的动词不定式作宾语补足语不定式在某些感官动词,如 feel, hear, listen to, watch, look at, notice, observe等,以及使役动词let, have, make等后作宾语补足语时,要省去to,但在被动语态中,不省略。
They made the workers work day and night. The workers were made to work day and night.The PLA men noticed the spy steal some papers. Let me hear you play the piano.在下列句型中Had better/had best + (not) do sth You’d better/best turn the bottle upside down to empty out the oilHad/would rather + (not) do sth I’m tired, I’d rather not go out this evening.Had/would rather/sooner + do sth. + than + do sth. 宁愿做某事而不愿做某事I’d rather stay at home tonight than go to the cinema.Prefer + to do sth + rather than + do sth She prefers to travel rather than attend the wedding.Cannot but + do sth. Or cannot choose/help but + do sthI can’t but think so. I can’t help but laugh on hearing his joke.Do nothing (= not do anything) but/except + do sthYou can do nothing but wait = you cannot do anything but wait.在系动词be后作表语当不定式在系动词be后作表语时,如果主语部分带有行为动词do,不定式就可省略to。
The only thing I can do is lie in bed. What I want to do is have a good rest.疑问词why引导的省略 Why not do sth? / why do sth? Why not?不定式省略动词原形如果一个动词在前面已经出现过,为了避免重复,这个动词可以省略Did you get the new stamps? No, I tried to, but there wasn’t any left in that post office.不定式的否定形式Not/never + 不定式 my father told me never to see her again. The door was not to open until 10 am.表示动作通常与主要谓语所表示的动作或状态几乎同时发生,或是在它之后发生。
