频度副词
1.定义
表示某一动作或状态出现的频率的副词被称为频度副词。
( 2 )表示具体频率的频度副词短语:once/twice a week“一周一次/两次”,four times a day“一天四次”,every day/week/year“每天/每星期/每年”等。
注意:表示三次或三次以上一般用“基数词+times”来表示。
2.用法

It often rains here in July.这里七月份经常下雨。
I usually drink a glass of milk before sleep.我睡觉前通常会喝一杯牛奶。
( 2 )频度副词一般置于实义动词之前,若句子里有情态动词、助动词或系动词be,则放在这类动词( 第一个 )的后面。sometimes可位于句首、句中或句尾。例如:
I’m hardly ever late for school.我上学几乎从不迟到。
Sometimes we play games in class.有时我们在课堂上做游戏。
( 3 )对频度副词或“次数+时间段”提问时要用how often,意为“多久一次”,用于询问某件事或某项活动发生的频率。例如:
