After() seemed an endless wait, it was his turn to enter the doctor’s office.


A、

not


B、

it


C、

what


D、

there


【正确答案】:C
【题目解析】:

这个句子是after(此处为介词:表示在时间,事件之后)引导宾语从句,括号处缺少主语成分,选项中BCD均可做主语,it seems...为固定句型,it在句中是形式主语,而且其完整形式通常为it seems to be 或it seems that....放在空白处是不合适的, there seems 是there be 句型的变形,其形式应该为there seems to be...,因此D选项也需要排除,只有C选项合适。

句意:经过了无休止的等待后,终于轮到他进医生的办公室了。
