--- How _____ hours do you sleep a day?

问题选择题

--- Well, about eight hours. But how _____ sleep do we students really need?

A．many; many

B．much; much

C．much; many

D．many; much

答案

答案：D

题目分析：根据hours可知，前面应该用many，因为many修饰可数名词的复数；根据sleep是不可数名词，故用much，因为much修饰不可数名词。所以本题选D。

点评：many 和much虽然都有“许多”的意思，但是many修饰可数名词的复数，而much修饰不可数名词。
