- 试题详情及答案解析
- The reason _______ he didn’t come was _______he was injured.
| A．that, because | B．why, that |
| C．why, because | D．that, that |
- 答案：B
- 试题分析：考查定语从句和表语从句。句意：。the reason是先行词，定语从句“he didn’t come”不缺少主语或宾语，是完整的，因此用关系副词why引导定语从句，排除A、D；was后跟表语从句，“he was injured”不缺少成分，that引导表语从句无意义，只起连接作用，且不可省略，the reason why...is that...可以看作一个固定句型，故选B。
考点：考查定语从句和表语从句
