问题: 三、选择

19、The teacher raised his voice _____ every one could hear her.
A.in order to
B.so as to
C.so that
D.since that

解答:

选C
由题意,我们知道横线上应填的是目的状语,可排除D
in order to 的用法是:in order to do sth 在这题中不合适,可排除A
so as to 的用法是:so as to do sth 在这题也不合适,可排除B

so that 做目的状语时的用法是:so that + 从句,这题横线后的正是一个句子,充当从句,所以应选C。
