In order to get there in time, they started early.(正)

　　They started early so as to get there in time.(正)

　　So as to get there in time, they started early.(误)

　　2. 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 children to come in.

　　She fetched several bottles which she placed on the counter for Harry to inspect.

　　3. 目的状语从句与不定式的转换

　　英语中的目的状语从句，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 meeting.

　　I came early (in order) for you to read my report before the meeting.
