一、概念
频率副词是表示动作发生的频率,多与一般现在时连用。频率副词是一般现在时的“标志词”,它们是表示频率的副词。这些词表示经常性动作或情况,不是某一具体动作,常用于一般现在时。这些频率副词在句子中的位置比较灵活,可以用于句首、句中和句末。在表示动作发生的频率程度上可这样表示:always>usually>often>sometimes >never。
二、频率副词的位置
1. 在be动词之后。如:
She is sometimes very busy. 她有时很忙。
2. 在第一个助动词或情态动词之后。如:
I will never forget the first time I met you. 我将永远忘不了和你的第一次见面。
3. 在实义动词之前。如:
We often go there. 我们常去那儿。
4. sometimes也可放在句首、句中或句末,often也可放在句末。如:
Sometimes she writes to me. 她有时候给我写信。
She writes to me often. 她经常给我写信。
注:如果有两个助动词,频度副词通常放在第一个助动词后面。
We have never been invited to one of their parties. 他们聚会,一次也没邀请过我们。
She must sometimes have wanted to run away. 她有时候一定想到过要逃走。

(1)I shall always remember my first day at school. 我将永远记住我上学的第一天。
(2)He is always smoking. 他总是抽烟。
★usually
usually可以指通常的动作,但是侧重已经形成的习惯,它是从已经形成的角度来说明动作。e.g.
(1)I usually do some shopping with my parents on Sundays. 我经常在星期天和我的父母一起去买东西。

有时候他骑自行车上班,有时候他乘公共汽车上班。
(2)Sometimes I helped my parents in the house. 有时候我帮助父母做家务。

模糊频率副词
以下些词都是表示事情发生频率的副词,也是不准确地说某事在一段间内发生的次数。
always 总是usually 通常often 经常
sometimes 有时hardly ever 几乎never 从来不
例如:
On weekends I always surf the Internet.
I usually watch TV.
I often sleep late.
I sometimes listen to music.
I hardly ever play computer games.
I never play soccer.
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 > hardly ever > never。
请看下面的图解:
always usually often sometimes never
100% 70—80% 60-70% 30-40% 0
精确的频率副词
以下这些频率副词可以准确地表达事情发生的频率。
一次 once 两次 twice 三次 three times
