- 试题详情及答案解析
- — Who called you up just now?
— Mary. She asked my homework.| A．if had I finished |
| B．if I had finished |
| C．I had finished |
| D．had I finished |
- 答案：B
- 试题分析：考查宾语从句。句义：—刚才谁打你的电话了？—Mary，她问我是否已经完成了家庭作业。所有的宾语从句都失业陈述语序，排除D项。根据句义可知表示的是不确定的事情，所以使用if；我完成作业是在她打电话之前，所以使用过去完成时。故B正确。
考点：考查宾语从句
