Question

English is a language shared by several diverse cultures, _________ uses it differently.

A．all of which

B．each of which

C．all of them

D．each of them

Answer 1

B

解析试题分析：句意：英语是一种被被几个不同的文化共享的语言，每种语言都有不同的用法。逗号后面是非限制性定语从句，所以排除C、D 选项；A. all of which 中的all强调整体，谓语用复数形式；B.each of which 则强调固个体，谓语用单数形式。非限制性定语从句中的谓语动词是uses ,是动词的单三形式，所以选B。 
如果逗号后有and，则选D，前后构成并列句。
考点：考查非限制性定语从句和主谓一致。
