Unit 1: How often do you exercise?
【语言目标】
会使用频率副词及短语；能描述课余时间的活动安排；会描述基本饮食结构。
1.How often do you exercise？你多久锻炼一次？
本句是对“动作发生的频率”进行的提问，其中“how often”是一个特殊疑问词。
所谓的“频率”指的是某个动作多长时间/多久发生一次。
试比较：How often do you swim ？你多久游一次泳？
How often does your father go to a movie？你爸爸多久看一次电影？
针对“how often”引导的问句所进行的回答：本单元常用的表示频率的短语有：once a week, twice a week, three times a month等等。当然，也可以用一些常见的频度副词来进行回答，如always ,usually, often, sometimes, hardly ever, never.
例：对划线部分提问：
He always takes a bus to school. 注：划线部分都是对“频率”的描述，所以答案为He takes a bus to school twice a week. How often does he take a bus to school？
He never takes a bus to school.
