30、riving为了减少空气污染，我们应 当乘坐公汽或地铁而不是开车。本句中To cut down air pollution是动词不定式作目的 状语。动词不定式做目的状语时的用法一、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。为了使目的意义 更加清楚或表示强调意义时，还可以在前面加in order to 或 so as tQ 例如：I've written it down in order notto forget.He shouted and waved so as to be no ticed.在句子中作谓语动词的状语的不定

31、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：To draw maps prop erly, you n eed a sp ecial pen.由in order to引导的目的状语，既可以置于句尾， 也可以置于句首，而由so as to引导的目的状语，只 能置于句尾，而不能置于句首。比较：They started early in order to get there in time.In order to get there in time, they started early.They started early so as to get there

32、in time.二、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。例如：He opened the door for the childre n to come in.She fetched several bottles which she pl aced on the coun ter for Harry to insp ect.三、目的状语从句与不定式的转换英语中的且的状语从句-还可以变为不定式或不定式短语作状语，从而使句子在结构上得以简化。可 分为两种情况：1. 当目的状语从句中的

33、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：We'll start early in order that/so that we may arrive in time.We'll start early in order to/so as to arrive in time.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。例如：I came early in order that you might read my report before the meeti ng.I came early (in ord
