How often + 助动词do(does或did) + 主语 + do sth.? 疑问词how often是问频率(多久一次),

（在这里助动词do(does或did) 是起帮助构成疑问的作用）与一般现在时或一般过去时连用，回答一般是用表示频率的副词，如：once, twice, three times…, sometimes, often, quite, often, never, every day, once a week , twice a month , three times a month , three or four times a month 等。

翻译：“你们多久到工厂去一次？”“每星期两次。” (“How often do you go to the factory?” “Twice a week. ”)

“他们多长时间举办一次舞会？”“通常每两周举办一次。” (“How often do they have a dancing party?” “Usually, once every other week.”)
