(C)18._______ do you study the hardest in your class for?
A.Why B.How C.What D.Which
为什么选C,请翻译整句话,

B 因为it's +adj+to do这个句型.live在这里是不及物动词所以要加介词.
C 因为在这里use是被动语态.杯子被用来喝茶.所以是be used.for是表原因.
used to do 表示过去常常做某事,而现在往往不做了
be used to doing 表示习惯于做某事
be used to do表示...被用来做某事 所以这句话也可以:
A cup is used to drink tea.
C 因为what.for=why
