频度副词

更新时间:2016-7-18 17:04:00  手机版

  频度副词:

  usually, sometimes, always, often等词在英文中被称为“频度副词”。用来表示动作频率,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%)hardly(10%)   never(0%)

  频度副词用法列举:

  ◆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)

  Li Ping is not always late for school. 李平上学不总是迟到。(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)

  The boy is always asking for money. 这个小男孩总是要钱。(厌烦)

  ◆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。

  My mother and I usually go shopping on Sundays. 我和妈妈通常在星期天去买东西。

  ◆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。

  he 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。

  ◆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。

  ◆seldom意为“很少”;never意为“从不”。这两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。

  The boys never eat chocolate and the girls seldom eat it. 男生从不吃巧克力,女生很少吃。

  Btter late than never. [谚语] 迟到(迟做)总比不来(不做)好。

  ◆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。

  ◆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?

  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。

  如果有两个助动词,频度副词通常放在第一个助动词后面。如:

  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。

  频度副词位于助动词之前两种情况:

  1.为了表示强调,频度副词有时也可位于动词be、助动词、情态动词之前,此时助动词等应重读。如:

  She always was late. 她老是迟到。

  I never can remember. 我永远也记不住。

  2. 在简略答语中,当频度副词与动词be、助动词或情态动词位于句末时,频度副词必须前置。

  “Philip is late again.” —“Yes, he always is.” —“菲利普又迟到了。”—“是的,他总是迟到。”

  “Can you park your car near the shops?” —“Yes. I usually can.”

  “你可以在商店附近停车吗?”—“是的,通常可以。”

  频度副词在否定句中的用法:

  在否定句中,有的频度副词位于否定词之前或之后均可,而有的频度副词则必须位于否定词之后,而还有的频度副词却必须要位于否定词。大致情况如下:

  1. 频度副词usually和often可位于否定词not之前或之后。

  他们不常开这样的晚会。

  正:They don’t often hold such parties.

  正:They often don’t hold such parties.

  星期日我们一般不在9点以前起床。

  正:We don’t usually get up before nine on Sundays.

  正:We usually don’t get up before nine on Sundays.

  在否定句中,频度副词用于句中或句首,有时但会导致意思不同。

  He doesn’t usually sleep for two days at a time. 他很少一连睡两天。

  Usually he doesn’t sleep for two days at a time. 他连续两天不睡觉是常事。

  2. 频度副词always总是位于否定词之后,不可位于否定句之前。

  Things are not always what they seem to be. 外表往往是靠不住的。

  Silence must not always be read as consent. 沉默并不见得一定意味着同意。

  3. 频度副词sometimes总是位于否定词之前,不可位于否定词之后。

  Jim is sometimes not very punctual. 吉姆有时不太准时。

  Debbie is sometimes not responsible for what she does. 黛比有时对她所做的事不负责任。

  频度副词位于句末的用法:

  1.sometimes常可用于句末。 如:

  We all get into trouble sometimes. 我们有时都会遇到麻烦。

  You can’t work all the time,it does you good to go out and enjoy yourself sometimes.

  你不能总是工作,有时出去放松一下会对你有好处。

  2. often有时可置于句末,但通常会带有very, quite, fairly, more, so等修饰语。如:

  We’ve been there quite often. 经常去那里。

  When I was young, I used to play tennis very often. 我年轻时经常打网球。

  Diana used to travel a lot. These days she doesn’t go away so often.

  娜过去经常旅游。最近她不常出门了。

  We're not exactly on intimate terms, but we see each other fairly often.

  虽算不上关系密切,但还常见面。

  注:有时也可不带修饰语,但主要见于否定句或疑问句。 如:

  He writes to me often. 他经常给我写信。

  Do you come here often? 你常来这儿吗?

  I don’t come here often. 我不常来这儿。

  3. usually有时也用于句末,其前不用修饰语。

  I’m not late, usually. 我通常不迟到。

  I get paid on Fridays usually. 我通常在星期五领工资。

  4.seldom 一般不用于句末,除非其前带有only,very等修饰。

  We go out very seldom. 我们绝少外出。

  I play basketball very seldom indeed. 我很少打篮球。

  5. always一般不用于句末,偶尔用于句末,此时它不表法“总是”,而表示“永远”。

  I’ll love you always. 我将永远爱你。

  另外,有时用于句末是因为句子有所省略的缘故。

  Generally they walked together on Sunday, but not always.

  他们一般在星期日一起散步,但并不总是如此。

  句中的but not always=but they didn’t always walk together on Sunday。

  频度副词位于句首的用法:

  1. sometimes常可用于句首。

  Sometimes she comes late. 有时她来得晚。

  Sometimes she didn’t agree with me. 有时她和我意见不一致。

  Sometimes we get a lot of rain in August. 有时在8月份雨水很大。

  2. often用于句首时,通常表示强调,且其前一般有quite, very修饰。

  3.usually有时也用于句首,其前不用修饰语。

  4.always一般不用于句首,除非是用在祈使句中。

  另外,never也可用于祈使句的句首。

  5.在正式文体中,表示否定意义的副词seldom, never可位于句首,但此时其后要用倒装语序。

  Seldom has there been such a happy meeting. 过去很少有过这样愉快的会议。

  Never did he think the book would be finished so soon. 他可没想到这本书会这么快看完

  另外,once a year (每年一次), twice a week (每周两次), three times a day (一天三次), every Saturday afternoon(每星期六下午)等,

  这些时间状语也表示频率,它们可以和频度副词用在同一个句子中,表达上没有重复。如:

  We usually go to the cinema four times a month. 我们通常一个月看四次电影。
