- 试题详情及答案解析
- The reason _____ they held a party was _____ it was Sue’s birthday.
| A．why; because | B．why; that |
| C．that; that | D．that; because |
- 答案：B
- 试题分析：考查定语从句和表语从句。句意：他们举办晚会的原因是给Sue过生日。the reason是先行词，定语从句不缺成分，用why引导定语从句，排除C、D；was后跟表语从句，表语从句不缺少成分，用that引导，排除D，The reason why...is/was that...“......的原因是......”，可以看作固定句型，故选B。
考点：考查定语从句和表语从句
