Is this the reason _____ at the meeting for his carelessness in his work?

A．he explained	B．what he explained
C．how he explained	D．why he explained

答案

A

解析

试题分析：句意：这就是他在会上解释的他的工作上的疏忽的理由吗？这里是定语从句，先行词是reason，关系词在从句中作explain的宾语，当然可以省去，how与why在从句中作状语，不能作宾语，故排除CD；what不能引导定语从句，故选A。
点评：本题难度适中。定语从句的考查关键在于定语从句的成分分析，如果缺少主语，宾语，表语，定语就使用关系代词，否则，就使用关系副词。

A. that          B. of which         C. which      D. whose
解析：D。whose 在从句中作定语，修饰hosts。
