how many times “多少次”，它不问动作发生的频率， 只询问次数， 即“多少次”。其答语为once，twice，three times 等。
单元语法

考题4：[甘孜] —How often do you play football, Peter
—______.
A. For one week B. One week ago
C. In one week D. Once a week
【点拨】For one week 一周，表示时间段；One week ago 一周前，表示过去的时间；In one week 一周后，表示将来的时间；Once a week一周一次，表示经常性的动作。根据“How often”可知是问频率。
