选择题
The speech ____________ by Professor Smith was so interesting that the students talked about it all that day.
A.to be delivered
B.to be given
C.being delivered
D.delivered
答案
答案:D
题目分析:原句意思是,由史密斯教授发表的演讲太精彩了,以至于学生们一整天都在谈论它。通过分析句子结构,句子主语“演讲”和非谓语动词“发表”之间是被动关系,所以应该用过去分词作定语,故选D。
点评:解答这类题时首先分析句子结构,通过主语与非谓语动词的关系,来判断具体使用非谓语动词应该用哪种形式。
