6、，表示频率的副词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
