中考英语频度副词及How问问频率及方式复习
一、专题讲解 
  1)频度副词
  知识点1:
概念:在英文中用来表示动作频率的词被称为“频度副词”,频度副词是表示与次数,频度有关的副词,
如:always(总是), usually(通常),frequently(经常) often (经常)sometimes(有时), seldom(不常),
rarely(极少),never(从不) once(一次), twice(两次),等。
知识点2:频度副词等级 :
all the time          100%;                 
almost , always      90%;
generally , usually    80%;
often , frequently      60-70%;
as often as not        40-50%;
sometimes , at times  20-30%;
occasionally , from time to time  10%;
hardly , seldom , rarely        5%;
never 0%。
知识点3:频度副词的位置以及用法
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.(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)
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seldomoften在句尾时常被veryquite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。
weigh的各种形式
Better 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
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助动词情态动词位于句末时,频度副词必须前置。
—“Philip is late again.” —菲利普又迟到了。
—“Yes, he always is.”—是的,他总是迟到。
— “Can you park your car near the shops?” — 你可以在商店附近停车吗?
—“Yes. I usually can.” —是的,通常可以。
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,还有的频度副词却必须要位于否定词之前。大致情况如下:
1. 频度副词usuallyoften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.
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。
