【应掌握的句子】
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。
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.”
“他多久去购一次物？”“一个月一次。”                                                          
“How often does he go shopping?” “He goes shopping once a month.”
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。
