对频度副词never提问，要用how often 多久一次；多经常.
how 加adj. 或adv.可以很多构成疑问词组，例如：how many多少； how much多少； how old多大年龄； how big 多大；how often多久一次，多经常；how soon多快，多久以后；how long多长时间；等等
always, usually, often, sometimes, never等表示时间频度的副词，通常用来说明在一段时间内做某事的多少或某种状态存在的次数的多少。
针对上面所说的频度副词和表示“在某段时间内某种动作的次数”的状语提问时，都要用how often。换句话说，如果要回答由how often提问的句子，我们通常要用频度副词或诸如every day, each week, once a week, twice a day, four times a month等来回答。例如：
1. —How often do you play football?
—I usually play football after school.
2. —How often does Mary go to the concert?
—She often goes to it on Saturday evening.
3.—How often does my daughter take the medicine?
—Three times a day.
