1、外研版高中英语必修二grammar 不定式作目的状语和结果状语从句 一、不定式和不定式短语作目的状语 不定式和不定式短语作目的状语，主要用来修饰动词，表示某一动作或状态的目的。1to do.这种形式可置于句首(加强强调，有逗号与句子隔开)或句尾(通常不用逗号隔开)。在句首时常译为“为了”；在句尾时常译作“以便，目的是”。The Government set up a working party to look into the problem.政府成立了工作组调查那个问题。To save time，our teacher has us do half the exercises in clas

2、s.为了节约时间，我们老师要求我们在课堂上做一半练习。名师指津：在句子中作谓语动词的状语的不定式或不定式短语，表示的是主语的目的，因此，其逻辑主语通常是句子的主语。比较：为了画好地图，你需要一支特殊的钢笔。To draw maps properly，you need a special pen.(正)To draw maps properly，a special pen is needed.(误)2in order to do.为了 这种形式更能突出目的性，既可以置于句首又可以置于句尾。Ive written it down in order not to forget.In order no

3、t to forget Ive written it down.为了不忘记，我已经把它写了下来。3so as to do.为了 这种形式与in order to do.一样突出目的性，但so as to do.只能位于句尾。They started early in order to/so as to get there in time.(正)In order to get there in time，they started early.(正)So as to get there in time，they started early.(误)名师指津：以上不定式的三种形式的否定式均是在to前加

4、not。We had better hurry up in order not to be late for class.为了不上课迟到，我们最好快点。4不定式的复合结构作目的状语 当不定式或不定式短语有自己的执行者时，要用不定式的复合结构(即在不定式或不定式短语之前加for名词或宾格代词)作状语。He opened the door for the children to come in.他打开门以便孩子们进来。She fetched several bottles for Harry to inspect.她取来几个瓶子为了让哈利检查。5目的状语从句与不定式的转换 不定式或不定式短语作目的

5、状语可以转换成目的状语从句。可分为两种情况：(1)当目的状语从句中的主语与主句中的主语相同时，可以直接简化为不定式或不定式短语作状语。例如：我们穿戴整齐以便早点动身。We dressed up in order that/so that we could start early.We dressed up in order to/so as to start early.(2)当目的状语从句中的主语与主句中的主语不相同时，要用动词不定式的复合结构作状语。我早点到来为了你在会前可以看我的报告。I came early in order that you might read my report

6、before the meeting.I came early for you to read my report before the meeting.二、结果状语从句 结果状语从句表示事情的结果，常置于主句之后。结果状语从句由so that，so.that.，such.that.三种形式来表示。1so.that.句型(1)so形容词/副词that从句 Some people were so moved by the sight that they began to cry.一些人对此情景如此感动，以致开始哭了出来。The ball struck him so hard that he ne
