模糊频度副词
这些词都是表示事情发生频率的副词，但是不能够准确地说某事在一段时间内发生的次数，只能体现大致频度。
精确频度副词:
以下这些频度副词可以准确地表达事情发生的频率。
一次 once
每天every day
两次 twice
每个月every month 三次 three times
每年 every year
Rule：once（一次）和twice（二次）需要特殊记忆。其他次数只要用“基数词＋times”来表达就可以了。
e.g. I drink milk every day.
I exercise once a week.
I go to the movies twice a month.
every day
每天 once a week
一周一次 twice a month
一 个月两次
four times a year
一年四次 once two weeks
两周一次 six days a week
一周六天
我每天喝牛奶。
我每周锻炼一次。
我一个月去看2次电影。
观察得出频度副词在句中的位置

3.Do you usually eat fish

4.He often comes to see us.

放在be动词、助动词和情态动词之后，实义动词之前。
2.精确频率副词:句尾
Ask：
He sometimes eats apples.
How often does he eat apples
