Question

________see the children before they went to bed, he came home early

A．So as to

B．In order to

C．So that

D．In order that

Answer 1

B

试题分析：考查短语及连词用法。本题的四个选项都可以在句子做目的状语。CD两项后面不能接句子；A项不能放在句首。句意：为了在孩子们上床睡觉之前看见他们，他很早就回家了。故B正确。
点评：要特别注意so that, in order that后面都只能接句子，so as to和in order to后面可以接短语；so as to不能放在句首。固定搭配的用法在平时要牢记。
