一道英语选择题,麻烦告诉我为什么这样选
I_to help you but I was not able to spare any time.I _a paper last night and I will finish it
tonight.
A wanted;have been writing B have wanted ;wroted
C had wanted;wrote D had wanted;was writing
答
was writing强调过去正在忙着呢，所以没时间搭手帮忙，然后had wanted是在忙之前打算的要帮忙。发生在was writing之前，是过去的过去，遂用过去完成时
答
i prefer answer A
答
我过去想要帮助你 强调对现在的影响 所以用过去完成时 但是当时正在忙着写东西 用过去进行时 明白了吗 谢谢
答
选B， 第一个空是 主句有现在完成时表示过去时，从句用过去时；第二个空就是一般过去时，昨天晚上。
