Mr Wangan article on how to improve spoken English last month, but I don’t know whether he has finished it.

A. has written

B. wrote

C. had written

D. was writing

答案：

A. has written

B. wrote

C. had written

(答案→)D. was writing

解析：此题旨在考查一般过去时态和过去进行时态的区别。一般过去时态表示动作已完成，而过去进行时态则表示动作并未完成，但后面分句指出”但我不知他现在是否写完”，因此答案为D。此题容易受last month的干扰而误选B项。
