1. How often do you exercise? 你（你们）多久锻炼一次身体？

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。

always(总是) > usually (通常) > often(经常) > sometimes(有时) > hardly ever(很少) > never(从不) 隔一段时间做某事数次用 数词 + 时间间隔 的结构构成。如： once a week 一周一次(―一次‖用特殊词 once) twice a day 一天两次(―两次‖用特殊词 twice)

three times a month 一个月三次(三次或三次以上用 基数词 + times 的结构构成) sometimes 与some times，sometime，some time

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。
