______ 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

Answer 1

D

解析試題分析：考查主謂一致。根據(jù)后面的is說明主語是單數(shù)形式。而ABC三項是復數(shù)形式。D項the number of…指…的數(shù)量。做主語時，謂語動詞用單數(shù)形式。故D正確。句意：參加訓練的人的數(shù)量是450.
考點：考查主謂一致
點評：本題考查了number形成的兩個短語的謂語動詞的單復數(shù)。A number of修飾可數(shù)名詞復數(shù)，謂語動詞用復數(shù)形式；the number of…指…的數(shù)量；做主語，謂語動詞用單數(shù)。
