---how many students are there in the classroom? ---_____Idon’t know where they have gone. A．No one B．None C．Nobody D．Nothing

Answer 1

B

试题分析：句意：上文有多少学生在教室里，一个都没有。none 既可以指代物也可以指代人，no one ,nobody只可以指代人，nothing只能够指代物。 2、none用于回答how many ,how much提出的问题，no one,nobody用于回答who提出的问题，nothing 用于回答what提出的问题。3、上文如果已经出现过的名词下文只能用none来替代（人或物）故选B
