题目

How wonderfui you are playing the piano!_____do you practice it a week?一道初中英语选择.
How wonderfui you are playing the piano!_____do you practice it a week?
----Twice.Practice makes perfect.
A.How often B.How many times
我想知道为什么不能选A,因为A也是提问频率的.

答案

这个问句的意思是：你一周练习几次?
所以选How many times
如果句末没有a week,就是你练习的频率是多少,这样才选How often
