- 试题详情及答案解析
- _______ from toothaches for some time, he had to go to hospital for an examination.
| A．Suffered | B．Being suffered |
| C．Suffering | D．Having suffered |
- 答案：D
- 试题分析：考查非谓语动词。句中的逻辑主语为he，与suffer之间为主动关系，根据时间状语for some time，表示时间有先后性，故用having suffered。句意：患牙痛一段时间了，他不得不去医院检查。故D正确。
考点：考查非谓语动词
