动词不定式的简介
动词不定式是一种非限定性动词,由to+动词原形构成,但在有些情况下to可以省略.它还是属于动词,本身可以带宾语和状语.动词不定式在句中可以作主语、宾语、表语、定语和状语,还可用在复合结构中,而且有完成式、进行式、完成进行式和否定形式.动词不定式的被动形式除了一般形式外还有其完成式和进行式.
动词不定式的时态、语态
动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性
动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出.这一使动者我们称之为 逻辑主语,其形式如下:
主动形式 被动形式
一般式 (not) to make (not) to be made
完成式 (not) to have made (not) to have been made
进行式 (not) to be making
完成进行式 (not) to have been making
(1)语态
如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者,不定式一般要用被动语态形式.
(2)时态
1) 现在时:一般现在时表示的动词,有时与谓语动词表示的动作同时发生,有时发生在谓语动词的动作之后.
He seems to know this.
I hope to see you again.= I hope that I'll see you again.我希望再见到你.
2) 完成时:表示的动作发生在谓语动词表示的动作之前.
I'm sorry to have given you so much trouble.
He seems to have caught a cold.
3) 进行时:表示动作正在进行,与谓语动词表示的动作同时发生.
He seems to be eating something.
4) 完成进行时:
She is known to have been wreaking on the problem for many years.
动词不定式的语法功能
作定语
⒈不定式作定语
不定式在句中作定语,置于被修饰的名词或代词之后.如:
①The next train to arrive is from Washington.
②Have you anything to be taken to your sister?
③Do you have anything to say on the question?
④Would you please give me some paper to write on?
⑤My wish to visit France has come true at last.
不定式短语作定语和被修饰词之间表示以下关系:
(1)表示将来的动作(例①).
(2)与被修饰词之间有动宾关系,如是不及物动词,则需加介词(例④).
(3)与被修饰词之间有动宾关系,同时与句中其它词之间又有逻辑上的主谓关系时,尽管有被动含义,却仍 用主动语态(例③);如只有动宾关系,而无逻辑上的主谓关系,则需用被动语态(例②).
(4)不定式作定语时,一般可转换为定语从句,例①to arrive=that will arrive.
