Question

【题目】________David’s classmate wanted to tell him was________great an effort his teacher had made to help him out.

A．What；what B．That；how

C．What；how D．What；that

Answer 1

【答案】C。

【解析】考查主语从句与表语从句。在题干中，was之前为主语从句，从句中him之后缺少直接宾语，故应用what作为引导词；was之后是表语从句，根据感叹句的句型“how＋adj.＋a/an＋名词＋主谓”可知，第二个空应用how，故选C。
