--Which of parents is a teacher?--____ A are B is C both D all不好意思,选项写错了,A Any B Either C Both D All

问题描述:

--Which of parents is a teacher?--____ A are B is C both D all
不好意思,选项写错了,A Any B Either C Both D All

选C.
--Which of parents is a teacher?
--Both(of my parents are teachers)
回答的部分事实上是个省略句,补全后就可以非常清楚是选C了.
就算不清楚这是个省略句,也可以用排除法,其他3个选项没有一个是符合语法的,所以直接排除ACD后选C.
