1、Grammar:动词不定式作定语和结果状语一 、动词不定式作定语 (1)不定式与所修饰词之间的关系 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。 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。 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 l

2、earn from Lei Feng. 我们制订了一个向雷锋学习的计划。 状语关系 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。 .Thats 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。(2) 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。

3、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)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。试对比： There is nothing to do.无事可做。（有“无聊感”） There is nothing to be done. 不能做什么了。（即“束手无策”了） There is nothing to see.没有东西值得看

4、。 There is nothing to be seen. 什么东西也看不见。拓：不定式作定语的几种情况：在chance,way,opportunity等名词后，既可用动词不定式，又可用“介词of+v.-ing”作定语。Im glad to have the opportunity to talk/of talking to you about biology. 我很高兴能有机会和你谈一谈生物学。 在ability,failure,promise,wish,tendency等名词后，通常用动词不定式作定语。 We have the ability to deal with any aggre

5、ssive behavior 我们有能力应对任何挑衅的行为。 The bosss promise to increase the workers pay was a reaction to their demand. 老板答应提高工人们的工资，这是对他们要求的一个回应。 当被修饰的名词或代词前有序数词修饰时，该名词或代词后也用动词不定式作后置定语。 In my family, my mother is always the first one to get up and wipe tables and chairs. 在我家，妈妈总是第一个起床擦拭桌椅的人。动词不定式作结果状语动词不定式作结果

6、状语的几种情况： 动词不定式表示结果时通常用基本形式且总是出现在句尾，其逻辑主语就是句子的主语。结果状语常常只限于learn,find,see,hear,be told,make(使得）等动词。 He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。 I had to shout to be heard. 我必须叫喊对方才能听得见。【误区警示】 only to do 结构表示意外的结果 He hurried to the station,only to find the train had left

7、他匆匆忙忙赶到车站，结果却发现火车已经离开了。 分词与不定式都可以作结果状语，但不定式经常表示一种出乎意料的、令人不快的情况，而分词表示的是自然而然的结果。 His parents died,leaving him an orphan. 他父母双亡，成了一名孤儿。 enough to do 结构 The boy is old enough to take care of himself. 这个男孩够大了，可以自己照顾自己。 . 写出划线部分所作成分 1.
