Question

The reason __________ she gave for not finishing the homework is that she was ill.

A．why

B．what

C．that

D．for

Answer 1

C

试题分析：考查定语从句：句意：她给出的没完成作业的原因是她生病了。先行词是the reason，定语从句中give缺少的是宾语，用that引导定语从句。选C。
点评：定语从句的考查主要就是考查关系词的辨析，关系代词that, which, whose, whom, as， who在句中做主语，宾语，表语或者定语；where, why, when在句中做状语。要分析句子成分，看缺少什么成分，就选用相应的关系词。
