Listen A number of students ____in the classroom.
A talk B talks C is talking D are talking

Listen A number of students ____in the classroom.A talk B talks C is talking D are talking
D,这个是现在进行时,students 是复数

D
有listen 用完成时

我认为应该选C
因为这里的主体是A number of students ,而不是students,所以应动词该用单数形式,而句首有一个Listen!所以应该用现在完成时,所以应该用is talking,即选C。

还不如直接用talking更方便

D
Listen表示正在听,而a number of 指的是一些,所以用复数are.
a number of ... 一些,很多
the number of... 什么的数量,总额

D

d

C这是在考主谓一致

D. "a number of" 这里表示“许多”,因此应视为复数形式。listen暗示应为进行时。

D are talking
I'm sure it is right

d
A number of 谓语用复数
The number of 谓语用单数

D a number of 是指许多的意思 应该用复数形式
