The basic features of the communication process are identified in one question:Who says _____ through what channel to whom?
A、what
B、when
C、how
D、such
【正确答案】:A
【题目解析】:通讯过程的基本特征可归结为一个问题:谁通过何种渠道向谁告知了什么 [题解]本题所缺的是says的宾语。how是副词,不能作宾语;when作代词时意为“什么时候”,不合句意;such作代词时是指上下文已经提到过的事物,也不合句意;只有what“什么”可以作says的宾语。
