Question

________ she couldn't understand was ________ fewer and fewer students showed interest in her lessons.

A．What ; why	B．That ; what
C．What ; because	D．Why; that

Answer 1

A

试题分析：句意：她不能理解的是越来越少的学生为什么对于她的课不感兴趣。第一空是what引导的主语从句，它在从句中作宾语，that不能在主句中作成分，why不能作宾语，故排除BD；第二空是why引导的表语从句，它在从句中作状语，根据句意故选A。
点评：本题难度适中。连词是近几年高考常考的语法项目，主要考查的是它们的用法及意义，还需正确理解句意及正确分析句子的成分才能做出正确的判断。

A.that; when                   B.which; that
C.that; before             D.which; when
解析：A。考查when表示“那时”的用法。根据句意，选A。
