　　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。

　　你们多久到工厂去一次？每星期两次。 ?
　　他多久去购一次物？＂＂一个月一次。 ?
　　2. ＂what do you usually do on weekends?＂ ＂ i usually play soccer.＂
　　＂周末你通常做什么？＂＂我通常踢足球。＂
　　第一个do为助动词, 在这起帮助构成疑问的作用；而第二个do则是实义动词。

　　周末你通常做什么？我通常看电影。 ？
　　周末她通常做什么？她通常看远足。 ？
　　3. ＂what’s your favorite program?＂ ＂it’s animal world.＂ ＂你最喜欢什么节目？＂
