此时国内不少书认为,这两个结构作主语,谓语均用单数。如:
One and a half months has passed. / A month and a half has passed. 已经过去了一个半月。
但是,国外一些词书则认为,谓语动词的数取决于这两个结构中名词的数:
One and a half months have passed. / A month and a half has passed. 已经过去了一个半月。
6.“the [a] number of+名词”作主语
该结构若用定冠词,其后谓语用单数;若用不定冠词,其后谓语用复数:
The number of students is 4000. 学生人数为4000。
A number of people were absent from the meeting. 许多人开会缺席。
注意类似结构:
The variety of goods in this shop is rich. 这家商店的品种丰富。
A variety of books have been published. 已出版了各种各样的书。
