| A． | How long | B． | How much | C． | How soon | D． | How often |
分析 William，你父母多久进行一次锻炼？--一周不到三次．
解答 答案：D 根据答句"Less than three times a week"（一周不到三次），可知回答的是父母做运动的频率．询问频率用how often．how long提问时间段；how much提问价格和不可数名词的数量；how soon提问多久之后．故选D．
点评 本题考查疑问词组．如果答句是three times，那么就应该用how many times提问．注意频率和次数的区别．
