Helen _____ a report on the state of the traffic last week but i don't know wheter or not she has finished it

A.wrote
B.had written
C.would wrote
D.was writting

选哪个？为什么？

D.was writting
“but i don't know wheter or not she has finished it”由此可见，“last week ”的时候是还没有“finish”的，所以选D，“上星期在写”。其他3个都不对。C.would wrote是过去将来时，其余两个都表示动作已经完成了。

D.was writting

D.was writing. 表示昨晚正在写。
