4． In order to / so as to

in order to　 和so as to 后接动词原形，用作目的状语时，二者用法一致，但in order to do语气强烈，可放在句首、句中；而 so as to do 语气较弱，只能放在句中，不能放在句首；它们的否定形式把not 放在to 的前面。

注意：in order to 引导目的状语从句时，不定式的逻辑主语同句子主语保持一致。

________ get a better score, she has been studying hard all day.

A. so has to　 B. in order to　 C. so that　 D. in order that　

(B, so that 和in order that 引导从句)
