【细嚼慢咽】 in order to的用法

　　in order to意为“为了……”，强调目的，后面接动词原形，可以放在主句的前面，也可以放在主句的后面。in order (not) to do sth.表示“为了（不）做某事”。如：

　　为了能让学生听见他（讲话），他大声地说。
　　In order not to be late for school, she took a taxi.

　　含有in order to的句子可以转变为由so that或in order that引导的状语从句。如：  
　　She spoke loudly in order to let us hear her.
　　= She spoke loudly in order that we could hear her.
　　= She spoke loudly so that we could hear her.
　　为了让我们能听见她，她说话很大声。
　　so as to也表示“为了;以便”之意，相当于in order to，其后跟动词原形，否定形式为so as not to，有时so和as to可以分开。如：  
　　Please take enough money with you so as to buy anything you want.
　　请带上足够的钱以便买任何你想的东西。
