Self-study
不定式作定语,一般都是作后置定语,修饰前面的名词或代词,常表示一个将来的动作,有时也表示过去某一特定动作。
动词不定式做定语
The Infinitive as the Attribute
一、被修饰词是不定代词
不定代词 something, nothing 等后面常用不定式作后置定语。
二、不定式作后置定语的情况
1. There’s nothing to worry about.
2. I have something important to deal with.
二、名词被特定词修饰
当名词被序数词或only, next, last, right等词修饰,中心词为不定式的执行者时用to do(主动式),中心词为不定式承受者时用to be done(被动式)。
二、不定式作后置定语的情况
那位男孩是最后一个走出山洞的。
这是要讨论的第三个问题。
That boy was the last to walk out of the cave.
This is the third question to be discussed.
三、不定式作定语与特定名词连用:
1.由动词派生的名词,原动词常用不定式作宾语,此类名词有wish,decision,refusal,arrangement,intention,agreement,hope,need,plan,promise,failure,attempt等
2.由形容词派生的名词,原形容词常用不定式作状语,此类名词有ability,eagerness,anxiety,patience,willingness等。
3.名词本身是抽象名词,常用不定式解释其中的内容,此类名词有chance,plan,means,courage,effort,measure,movement,opportunity,power,reason,right,skill,strength,idea,way,approach等。
三、不定式与所修饰词之间的关系
①主谓关系
被修饰的名词或代词实际上是不定式的逻辑主语。
We need someone to help with the work.
(someone will help with the work)
我们需要有人来帮忙做这工作。
②动宾关系
被修饰的名词或代词是动词不定式的逻辑宾语。
I have many letters to write.
(to write many letters)
我有许多信要写。
注意:1.不定式与其所修饰的词构成逻辑上的动宾关系,而该不定式为不及物动词时,其后须加上适当的介词,构成及物动词短语。
I am looking for a room to live in. 我正在找个房间住。
I need a piece of paper to write on.我需要一张写字用的纸。
There is nothing to worry about.没什么可担心的。
*不定式作定语且所修饰的名词是time,place或way时,不定式后的介词一般要省去。
He had no money and no place to live.他没有钱也没有地方住。
③同位关系
不定式与所修饰的名词指的是一回事。
We have made a plan to learn from Lei Feng.
我们制订了一个向雷锋学习的计划。
④动状关系
被修饰的名词实际上表示动词不定式动作的方式、时间等。这些名词是抽象名词。
That's the way to do it.那样做才对。
I have no time to go there.我没有时间去那儿。
1. I have a lot of things to do tomorrow.
2. Please give me something to drink.
3. He will show you the right path to take.
在一些固定句型中,动词不定式作定语用__________表__________,如 have / get / give / show sth to do。
注意:当不定式修饰的名词或代词为不定式动作的承受者时,不定式主动形式与被动形式的含义有所不同。
如:
She has two children to take care of. (主语自己照顾)
She has two children to be taken care of. (别人帮助主语照顾)
如果不定式为主动,则不定式逻辑主语为句子主语, 如果不定式为被动,则不定式逻辑主语不是句子主语。
