题型：不详难度：来源：
It was quite a long time ________ I made it out what had happened.| A．after | B．before | C．when | D．since |
|
答案
| B |
解析
| 选B。“It + be + 时间名词+before / since”从句句型中，连词before 与since 混淆。用before引导时，句意是“过了多久才……”，主句中的be动词为过去时或将来时态；用since引导时，其句间是“自从……以来已经多久了”，主句中的be动词多为现在时(或现在完成时)或一般过去时(此时since从句要用过去完成时)。 |
