After her husband had gone to work and the children ___to school,she went upstairs.A.had sentB.were sent C.had been sentD.were sending这句话中为什么选C,不选B
句中有个and
而and连接的两个句子要求前后时态一致
and前的那句her husband had gone to work 中had gone是过去完成时
所以and后面那句the children ___to school也要用过去完成时,即要用had been sent
选C.
因为and连接的前后应该时态保持一致,had gone是过去完成时,所以要用had been sent
C, had gone to work 是完成时,用and来连接的时态保持一致。
c 都要用过去完成时,前面有一个had done了
你好。你这样吧。你把下面的句子变成被动语态,这样你的问题就解决了:
After she had sent her children to school, she went upstairs.
--------After her children HAD BEEN SENT to school, she went upstairs.
语法原理:先送孩子上学,然後她到楼上去。
and前后连接的时态必须一致啊 前面用的had gone to 后面就得用had been sent 还有 had been sent 表被动
