By the time she ________ tomorrow, the work ________.| A．arrives ; will be finished | | B．arrives ; will have been finished | | C．will arrive ; will have been finished | | D．arrives ; will have finished |
|
答案
| B |
解析
| 考查时态。By+将来的时间，主句用将来完成时；by+过去的时间，主句用过去完成时。By引导的从句用一般现在时代替将来时。work和finish主句是动宾关系，故用被动语态；再根据tomorrow可知，主句用将来完成时；综合用将来完成时的被动语态。句意“到明天她到达的时候，工作已经被做完了。”故选B。 |
