Question

【题目】The speaker raised his voice _____ make himself _____ by the listeners．

A．so that; heard B．in order to; hearing

C．so as to; heard D．to; to be heard

Answer 1

【答案】C

【解析】句意：讲话者提高嗓门，这样就可以使观众听到自己的声音。so that(以便，为了 ……）引导目的状语从句，显然后面不是一个完整的句子，排除A。因为make oneself done(使自己被……），第二个空需要填过去分词，排除B、D。so as to do表目的，所以选C。
