Unit 1 How often do you exercise?
重点语法：频率副词
询问别人做某事的频繁程度
提问用 How often 引导特殊疑问句
回答用 always, sometimes, twice a day 等频率副词。
例句：A: How often do you watch TV?(你多长时间看一次电视？)
B: I watch TV every day.(我每天都看电视。)
A: What's your favorite program?(你最喜欢的节目是什么？)
B: It's Animal World.(是《动物世界》。)
A: How often do you watch it?(你多长时间看一次这个节目？)
主要频率副词的等级排序：
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)
four times a year 一年四次
