Unit 7 知识点讲义
一.频率副词:表示动作频率,但程度上有区别的副词叫频率副词。
用法:频率副词的用法
①我们按照频率发生的高低,可以将这几个词排列为:
always>usually>often>sometimes>seldom>never
总是 通常 常常 有时 很少 从不
其他频率副词:once,twice,once a week,twice a day
②对频率副词提问时,用how often如:
I sometimes write to my brother.(对划线部分提问)
________ ________ do you write to your brother?
③频率副词的位置
通常放在be动词之后。如:
I am always very happy on my birthday.
主要放在动词之前。如:
My father usually walks home.
主要放在情态动词之后。如:
I will always love you.
在答句中,频率副词必须放在助动词之前。
Do you often go there?--Yes,i often do
(sometimes可以放句中,句首,句末。Often一般不放句首,可放句中,句末)
④频率副词并不影响句中动词的变化。
My father usually walks home.
