初中英語(yǔ)知識(shí)點(diǎn):頻度副詞

編輯: 逍遙路 關(guān)鍵詞: 初中英語(yǔ) 來(lái)源: 高中學(xué)習(xí)網(wǎng)

頻度副詞:
是表示動(dòng)作發(fā)生頻率的詞。
常見的有:
ever, never, rarely, seldom, once, often, occasionally, constantly, frequently, usually,continually, always 等。
例如:He often came to see us.
She always was late.
常見頻度副詞在表示程度上有別,按頻率大小排列如下:
always(100%)>usually(80%)>often(60%)>sometimes(40%)>seldom(20%)>hardly (10%)>never(0%)



常見程度副詞用法列舉:
◆always 頻率最高,表示動(dòng)作重復(fù)、狀態(tài)繼續(xù),表示“一直、總是”,其反義詞為never。always等與not連用時(shí),表示部分否定。如:
The rich are not always happy. 有錢的人并不總是快樂(lè)的。
如果要變?yōu)榉穸ň洌瑧?yīng)將always改為never才能全部否定。如:
Li Ping is always late for school. 李平上學(xué)總是遲到。
Li Ping is never late for school. 李平上學(xué)從不遲到。(全部否定)
Li Ping is not always late for school. 李平上學(xué)不總是遲到。(部分否定)
頻度副詞通常和一般現(xiàn)在時(shí)連用,表示動(dòng)作發(fā)生的頻率。但always與進(jìn)行時(shí)連用時(shí),并不強(qiáng)調(diào)動(dòng)作正在進(jìn)行,而是表示贊嘆、厭煩等情緒。如:
He is always thinking of others. 他總是想著別人。(贊嘆)
She is always asking silly questions. 她總是問(wèn)些愚蠢的問(wèn)題。(厭煩)
The boy is always asking for money. 這個(gè)小男孩總是要錢。(厭煩)

◆usually意為“通常”,表示習(xí)慣性動(dòng)作或狀態(tài),很少有例外。如:
We usually go to school at seven in the morning. 我們通常在早上七點(diǎn)上學(xué)。
My mother and I usually go shopping on Sundays. 我和媽媽通常在星期天去買東西。

◆Often意為“經(jīng)常,時(shí)常”,表示反復(fù)性的動(dòng)作或狀態(tài),中間有間斷,不如usually那么頻繁。其反義詞是seldom。often在句尾時(shí)常被very或quite修飾。如:
It often rains here in April. 這兒四月份常下雨。
he boys often eat noodles and the girls sometimes eat them. 男生經(jīng)常吃面條,女生有時(shí)吃。
I often chat with my friends under the big tree. 我經(jīng)常在這棵大樹下和朋友聊天。
He writes to his friends quite often. 他常給他的朋友寫信。

◆sometimes意為“有時(shí)”,頻率不及often,表示動(dòng)作偶爾發(fā)生,間斷時(shí)間較長(zhǎng)。其位置比較靈活,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.
有時(shí)我們?nèi)タ措娪,有時(shí)我們?nèi)ド⒉健?BR>I sometimes watch TV in the evening. 我有時(shí)晚上看電視。
My father has lunch in the factory sometimes. 我父親有時(shí)在工廠吃午飯。

◆seldom意為“很少”;never意為“從不”。這兩個(gè)副詞表示否定意義,動(dòng)作幾乎不會(huì)發(fā)生。如:
He seldom eats breakfast. 他很少吃早餐。
The little girl seldom goes out. 這個(gè)小女孩很少外出。
I will never forget your kindness. 我永遠(yuǎn)忘不了你的好意。
The boys never eat chocolate and the girls seldom eat it. 男生從不吃巧克力,女生很少吃。
Btter late than never. [諺語(yǔ)] 遲到(遲做)總比不來(lái)(不做)好。

◆hardly具有否定意義,表示“幾乎不、簡(jiǎn)直不”,除非特殊情況,否則不會(huì)發(fā)生。如:
The boy is so young that he could hardly understand it. 這個(gè)孩子太小了,不可能懂得這件事。

◆對(duì)上述頻度副詞提問(wèn)時(shí),用how often。如:
I write to my brother sometimes.
→How often do you write to your brother?

頻度副詞在句中不同位置的用法比較:
一、頻度副詞在否定句中的用法
在否定句中,有的頻度副詞位于否定詞之前或之后均可,而有的頻度副詞則必須位于否定詞之后,而還有的頻度副詞卻必須要位于否定詞。
大致情況如下:
1. 頻度副詞usually和often可位于否定詞not之前或之后。
他們不常開這樣的晚會(huì)。
正:They don’t often hold such parties.
正:They often don’t hold such parties.
星期日我們一般不在9點(diǎn)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,頻度副詞用于句中或句首,有時(shí)但會(huì)導(dǎo)致意思不同。
He doesn’t usually sleep for two days at a time. 他很少一連睡兩天。
Usually he doesn’t sleep for two days at a time. 他連續(xù)兩天不睡覺是常事。

Do you come here often? 你常來(lái)這兒?jiǎn)?

5. always一般不用于句末,偶爾用于句末,此時(shí)它不表法“總是”,而表示“永遠(yuǎn)”。

另外,有時(shí)用于句末是因?yàn)榫渥佑兴÷缘木壒省?BR>Generally they walked together on Sunday, but not always.

5.在正式文體中,表示否定意義的副詞seldom, never可位于句首,但此時(shí)其后要用倒裝語(yǔ)序。

另外,once a year (每年一次), twice a week (每周兩次), three times a day (一天三次), every Saturday afternoon(每星期六下午)等,
這些時(shí)間狀語(yǔ)也表示頻率,它們可以和頻度副詞用在同一個(gè)句子中,表達(dá)上沒(méi)有重復(fù)。如:
We usually go to the cinema four times a month. 我們通常一個(gè)月看四次電影。



頻度副詞的用法:
頻度副詞是副詞的一種,在初中階段常用的有四個(gè),即always, usually,often,sometimes。它們的用法如下:
一、頻度副詞在句中的位置。
1.頻度副詞在句中習(xí)慣上位于be動(dòng)詞、助動(dòng)詞之后,行為動(dòng)詞之前。如:
She is often late for school.她上學(xué)經(jīng)常遲到。
He usually goes to bed at about 12.他通常(午夜)十二點(diǎn)鐘睡覺。
When do you usually get up in the morning?早上你通常什么時(shí)候起床?
2.sometimes是個(gè)特殊的頻度副詞,既可以放在be動(dòng)詞、助動(dòng)詞之后,行為動(dòng)詞之前,也可以放在句首,還可以放在句尾。如:
I sometimes think that it is a great mistake.我有時(shí)想這是一個(gè)大錯(cuò)。
Sometimes I help my mother in the house.有時(shí)候我?guī)椭鷭寢屪黾覄?wù)。
3.often可以放在句中,也可放在句尾,習(xí)慣上不放在句首。如:
We have been there quite often.我們經(jīng)常到那兒去。
She writes to me often. 她經(jīng)常給我寫信。
4.如果有兩個(gè)助動(dòng)詞,頻度副詞通常放在第一個(gè)助動(dòng)詞后面。如:


We have never been invited to one of their parties. 他們聚會(huì),一次也沒(méi)邀請(qǐng)過(guò)我們。


She must sometimes have wanted to run away. 她有時(shí)候一定想到過(guò)要逃走。
5.這些頻度副詞的位置與句中謂語(yǔ)動(dòng)詞有無(wú)助動(dòng)詞有關(guān)。句中沒(méi)有助動(dòng)詞時(shí),副詞置于動(dòng)詞be之后,其它動(dòng)詞之前。
頻度副詞位于助動(dòng)詞之前兩種情況:
①為了表示強(qiáng)調(diào),頻度副詞有時(shí)也可位于動(dòng)詞be、助動(dòng)詞、情態(tài)動(dòng)詞之前,此時(shí)助動(dòng)詞等應(yīng)重讀。如:
She always was late. 她老是遲到。
I never can remember. 我永遠(yuǎn)也記不住。
②在簡(jiǎn)略答語(yǔ)中,當(dāng)頻度副詞與動(dòng)詞be、助動(dòng)詞或情態(tài)動(dòng)詞位于句末時(shí),頻度副詞必須前置。
?“Philip is late again.”
?“Yes, he always is.”
?“菲利普又遲到了!
?“是的,他總是遲到!
? “Can you park your car near the shops?”
?“Yes. I usually can.”
? “你可以在商店附近停車嗎?”
?“是的,通?梢!
6.頻度副詞后的動(dòng)詞可以是動(dòng)詞的任何形式,具體什么形式和頻度副詞本身沒(méi)有關(guān)系。
如:
I have never been to the moon.
He sometimes goes to school by bike.

二、表示頻度方面的區(qū)別:
1.always是頻度最大的詞,意為"總是;永遠(yuǎn)"。如:
I shall always remember my first day at school.我將永遠(yuǎn)記住我上學(xué)的第一天。
2.usually意為"通常",即很少例外,頻度僅次于always。如:
What do you usually have for breakfast?你通常早餐吃什么?
3.often意為"經(jīng)常",在頻度上不如usually那么頻繁。如:
Li Ping often does his homework in the afternoon.李平經(jīng)常在下午做作業(yè)。
4.sometimes意為"有時(shí)候",頻度比often小,表示動(dòng)作偶爾發(fā)生,間斷較大。如:
1.I sometimes go to the library.我有時(shí)去圖書館。
2.Sometimes I read a book in the evening.我有時(shí)在晚上看書。

三、頻度副詞與not連用時(shí),表示部分否定;對(duì)頻度副詞進(jìn)行提問(wèn)時(shí),要用how often。如:
1.A great scholar is not always a very wise man.大學(xué)者未必一定是極聰明的人。
2.We go to the cinema sometimes.(對(duì)劃線部分提問(wèn))
How often do you go to the cinema?
