how often 多久一次。How often + 助动词 do(does 或 did) + 主语 + do sth.? 用来询问（主语）多久进行一次某个（活动）的频率；回答时可用once / twice / three times a day, sometimes, never, often等。

辨析how often、how long、how soon、how many times

① how often “多久一次”，用来提问频率。

② how long “（延续）多长时间”，用来询问时间的长短；也可询问某物的长度。回答时用for 或since引导的时间状语。

③ how soon “还要多久（时间）才……”，一 般用将来时态，回答用in引导的时间状语。

④ how many times “多少次”，用于询问次数，回答用once, three times等。

(2)twice a week “一周两次”。once表示“一次”， 

   twice表示“两次”，“三次及以上”要用“基数词+times”表示。three times 三次
