问题补充:
He told me a piece of news, terrible.
A. I think it is
B. I think which is
C. which I think it is
D. which I think is
答案:
A. I think it is
B. I think which is
C. which I think it is
(答案→)D. which I think is
解析:考查定语从句,先行词是a piece of news,定语从句中I think是插入语,用which引导做定语,it是多余的,句意:他告诉我一个我认为很可怕的消息。选D。
