频度副词
(1)频度副词的含义
★频度副词是表示动作发生的频率,多与一般现在时连用。频度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。
主要的频度副词always>usually>often>sometimes>rarely>hardly never>never
① 100﹪ always意为“总是,一直;始终”。这是频率最大的词,表示动作重复,状态继续,中间没有间断。
如:Mary is always late for school.玛丽总是上学迟到。
He always comes late. 他总是迟到。
② 90﹪ usually意为“通常,经常”,表示习惯动作,频率仅次于always,相当于most often。表示除个别情况外,基本上没有变化。
如:He usually gets up at 6 o'clock.他通常6点钟起床。
I usually go to bed at 10:00. 我通常10点钟睡觉。
③ 70﹪ often意为“时常,经常,常常”,表示动作重复,中间有间断,表示发生的频率比usually要小,但比sometimes要大。
如:I often go to school by bike,but sometimes I go to school by bus.
我经常骑自行车上学,但有时乘公共汽车去。
They often clean the classroom after school. 他们常常在放学后打扫教室。
④ 40﹪ sometimes意为“有时”,表示发生的频率比较小。sometimes一词在书写时要十分小心,若分开写成 some times就成了“好几次,数次”。 sometimes的位置较为灵活,可位于句首、句中或句末。
如:They are always late for school. 他们总是上学迟到。

频度副词
1.定义usually/ sometimes/always/often等词在英文中被称为“频度副词”,是用来表示动作频率的,但程度上有别。常见频度副词按频率大小排列如下:
always(100%)>usually(80%)>often(60%)>sometimes(40%)>seldom(20%)>
never(0%)
2.频度副词的位置
◆频度副词在句中习惯上位于be动词、助动词等之后,行为动词之前。
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 this lesson. 我将永远忘不了这一课。
3. 在实义动词之前。如:
We often go there. 我们常去那儿。
◆sometimes也可放在句首、句中或句末,often也可放在句末(一般不放在句首)。如:
Sometimes she writes to me. =She writes to me sometimes. 她有时候给我写信。
She writes to me often. 她经常给我写信。
频度副词的用法
◆always 频率最高,表示动作重复、状态继续,表示“一直、总是”,其反义词为never。always等与not连用时,表示部分否定。如:
The rich are not always happy. 有钱的人并不总是快乐的。
如果要变为否定句,应将always改为never才能全部否定。如:
Li Ping is always late for school. 李平上学总是迟到。
Li Ping is never late for school. 李平上学从不迟到。(全部否定)
