Mr Smith _________ a book about China last year but I don’t know whether he has finished it.
A. has written
B. wrote
C. had written
D. was writing

Answer 1

答案D
这是由 but I don’t know whether he has finished it 这一句话的语境决定的，全句意为“史密斯先生去年在写一本书，但我不知道他现在是否写完了”。有的同学可能由于受 last year的影响而误选B。但若选B，则句子前半部分的意思则变为“史密斯先生去年写了一本书”，既然是“写了”，那么这与下文的“但我不知道他现在是否写完了”相矛盾。
