(正)To draw maps properly, a special pen is needed. (误)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. (正)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)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 children to come in.She fetched several bottles which she placed on the counter for Harry to inspect.目的状语从句表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导，例如: You must speak louder so that/in order that you can be heard by all.He wrote the name down for
