如何對頻度副詞提問

對頻度副詞提問，英語通常用how often。How often的本意是“多經(jīng)�！�，通常譯為“多久”“隔多久”。如：

How often do you wash your hair? 你多長時間洗一次頭發(fā)?

How often do you go to church? 你隔多久去做一次禮拜?

How often do you have a bad back? 你多長時間腰痛一次?

How often do the buses run? 公共汽車隔多長時間一班?

How often do you hear from your sister? 你多長時間接到你姐姐一次信?
