选择题
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
答案：A
题目分析：首先判断到底引导的什么从句，第一步应先将反问句还原成陈述句，This is the reason at the meeting for his carelessness in his work。句意：他工作粗心是他在会议上解释的原因吗？很明显是定语从句。先行词the reason,引导词that作宾语省略。故选A。
点评：此题很容易受the reason why…is that句型的影响，注意必须先理解句意。此外，这种疑问形式的句子，最好还原成陈述句有助于找准先行词。比如下次如遇上“Is this school _____...?”和“Is this the school_____...?”前者缺先行词，而后者的先行词为the school.
