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

(  1  )频度副词通常和一般现在时连用,表示在特定时间内某动作或状态出现的频率。例如:

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:
