问题选择题

______ the students who took part in the training is 450.

A．A number of

B．A lot of

C．Lots of

D．The number of

答案

答案：D

题目分析：考查主谓一致。根据后面的is说明主语是单数形式。而ABC三项是复数形式。D项the number of…指…的数量。做主语时，谓语动词用单数形式。故D正确。句意：参加训练的人的数量是450.

点评：本题考查了number形成的两个短语的谓语动词的单复数。A number of修饰可数名词复数，谓语动词用复数形式；the number of…指…的数量；做主语，谓语动词用单数。
