在英文中用来表示动作频率的词被称为“频度副词”,例如:usually/sometimes/always/等,这些词在程度上有区别。

语法点讲解

1. 意义:

表示动作发生的次数、频率的副词。

always, sometimes, never, usually,often ...

常用频度副词的频率排序:

always 100%

usually 90%

normally 80%

often 70%

sometimes 50%

occasionally 30%

seldom 20%

hardly ever 5%

never 0%

2. 频度副词出现的位置(用法):

1.频度副词通常放在实意动词之前(1),be动词之后(2),如果句子中出现情态动词或助动词,则放在情态动词、助动词与实意动词之间(3)。

如:

I always do homework in the afternoon.(1)

He is never kind to us.(2)

She can never know your secret.(3)

2.频度副词的特殊位置:表示次数的频度副词,如once, twice,可以放在动词后或句末(4);有的频度副词也可放在句首表示强调(5)。

如:

The car broke down twice.(4)

Sometimes I go fishing with my dad.(5)

3. 常用频度副词精讲:

1. 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.(全部否定)Li Ping is not always late for school. (部分否定)频度副词通常和一般现在时连用,表示动作发生的频率。但always与进行时连用时,并不强调动作正在进行,而是表示赞叹、厌烦等情绪。如:He is always thinking of others. 他总是想着别人。(赞叹)She is always asking silly questions. 她总是问些愚蠢的问题。(厌烦)

2. usually 意为“通常”,表示习惯性动作或状态,很少有例外。如:We usually go to school at seven in the morning. 我们通常在早上七点上学。

3. Often意为“经常,时常”,表示反复性的动作或状态,中间有间断,不如usually那么频繁。其反义词是seldom。often在句尾时常被very或quite修饰。如:

It often rains here in April. 这儿四月份常下雨。The boys often eat noodles and the girls sometimes eat them. 男生经常吃面条,女生有时吃。I often chat with my friends under the big tree. 我经常在这棵大树下和朋友聊天。He writes to his friends quite often. 他常给他的朋友写信。

4. sometimes意为“有时”,频率不及often,表示动作偶尔发生,间断时间较长。其位置比较灵活,放在句首、句中、句末都可。如:Sometimes we go to the cinema and at other times we go for a walk.有时我们去看电影,有时我们去散步。I sometimes watch TV in the evening. 我有时晚上看电视。My father has lunch in the factory sometimes. 我父亲有时在工厂吃午饭。

5. seldom意为“很少”,这个副词表示否定意义,动作几乎不会发生。如:He seldom eats breakfast. 他很少吃早餐。The little girl seldom goes out. 这个小女孩很少外出。I will never forget your kindness. 我永远忘不了你的好意。

6. hardly具有否定意义,表示“几乎不、简直不”,除非特殊情况,否则不会发生。如:The boy is so young that he could hardly understand it. 这个孩子太小了,不可能懂得这件事。

7. never意为“从不”表示动作不会发生.例如:I never go to school by taxi.我从不坐出租车去上学。The boys never eat chocolate and the girls seldom eat it. 男生从不吃巧克力,女生很少吃。

8.对上述频度副词提问时,用how often。如:I write to my brother sometimes.→How often do you write to your brother?

4. 句型转换和其他频度用词:

(1)[句型转换]

疑问句:用how often对频率进行提问。

如:

-How often do you go swimming?

-I sometimes go swimming.

-How often does she play the piano?

-She plays the piano every day.

(2)[其他表示频率的单词或词组]

1. 表示某事发生的次数:

once(一次)、twice(两次),三次及三次以上都用具体数词加times,如three times(三次)、ten times(十次)。

如果某事经常发生,可用“a”加一个表示时间段的词,表示此事在一段时间内发生的次数。

如:

Joey and I meet twice a week.

She does sports three times a month.

2. 表示某事每隔一段时间发生:

every day(每天)、every week(每周)、every month(每月)every other day(每隔一天)、every other week(每隔一周)、every other year(每隔一年)……
