Step 4　问题探究
1．How often与How many times的用法区别
(1)你多久上一次钢琴课？
How__often__do__you__have__a__piano__lesson
(2)你一周上几次钢琴课？
How__many__times__do__you__have__piano__lessons
How__often＋助动词do(does或did)＋主语＋do sth.？是对频率(多久一次)进行提问。疑问词how often(在这里助动词do，does或did是起疑问的作用)与一般现在时或一般过去时连用，回答一般是用表示频率的副词always，usually，often，sometimes，never等或者是“次数＋一段时间”，如once/twice a month，three times a month，three or four times a month等。也可以用every day，every year，every week等短语来回答。
How__many__times对次数进行提问，其答语为once，twice，three times等表示次数的单词或短语。
