The teacher told him to speak louder by everybody.

A. so as to be heard

B. so as to hear

C. in order that heard

D. in order to hear

答案：

(答案→)A. so as to be heard

B. so as to hear

C. in order that heard

D. in order to hear

解析：句意：老师让他大声讲话，为了让每一个人都听到。so as to意思是为了，且“他”是被听到，故用被动语态；in order that后面要接从句；in order to意思是为了，且“他”是被听到，故用被动语态，只有A正确，选A。
