The kids ______ their reading when their class teacher came into the room.
A.just have finished B.are just finishing
C.have just finished D.had just finished
详解,谢
答
这题的答案应该是D。
原题“came into the room”告诉我们整个句子的时态是过去时；
然后根据题意，当老师进来的时候，kids的动作已经完成，结合起来我们应该用过去完成时。所以因该用had而不是have。
答
d 首先这是一个由when引导的时间状语从句 而主语kids和finished之间没有被动的含义 所以排除b 而c 形势本身错误 故排除 现在答案只有a d 要根据具体的语境 从came into the room可以看出 在这里时态应该是一般过去式...
