关系副词用法:
1.关系副词兼有副词与连接词两种作用,在不及物动词的连接中要求用关系副词。
2.关系副词所引导的形容词子句用于修饰主要子句中的某一名词或代名词,被修饰的词称作先行词,关系副词要放在先行词之后。
例如:关系副词when在定语从句中用作状语,表示时间,用以修饰表示时间的先行词。
3.关系副词主要有三个,即when,where,why。此外that也可代替关系代词引导代词子句。
4.关系副词=preposition(介词)+relative pronoun(关系代词)
例如:where=in which,when=on which,why=for which
这些关系副词在从句中做状语。
Would you please tell me the way how I can get to the zoo?
你能告诉我去动物园的路吗?(the way是先行词。)
This is the place where(that) I first met her.
这是我第一次见到她的地方。
在口语中that可以充当关系副词,代替when,why,how,只有先行词是the place时,才可代替where。
A:When should we start to work?
B:The sooner (we start),the better (it will be).
我们应该什么时候开始工作? 越早越好。
the作关系副词是引导副词子句,句子结构一般为:The+比较级...+the+比较级...,第一个the是关系副词。
5.time,day,year,place,house,reason,way等作先行词时可以被省略,其后的子句不再是形容词子句,而变成名词子句或副词子句。
中文:这是他出生的地方。
This is where he was born.
where he was born是名词子句。
This is the place where he was born.
where he was born是形容词子句。
中文:我将在第一次见到她的地方见她。
I'll meet her at the place where I first met her.
where I first met her是形容词子句。
I'll meet her where I first met her.
where I first met her是副词子句。
6.关系副词有限定用法,指的是关系副词引导的形容词子句只修饰先行词。
We were very happy in those days when we studied in school.
我们在学校里上学的那些日子里很快乐。
7.关系副词有补述用法,即关系副词引导的是对等子句而不是形容词子句,主要用于对主要子句中的不足之处加以补充,前面都要加逗点与主要子句分开。
Tom got married the day before yesterday,when it was his birthday too.
汤姆前天结婚了,那天也是他的生日。
8.wherever,whenever,however是复合关系副词,表示"不论",引导一个修饰主要子句里的动词的副词子句,可加强语气或表示让步。
Wherever he goes,he would bring an umbrella with him.
不论他去那里,他都带着一把雨伞。
定语从句中关系词省略的6种情形:
关系词有时可以省略,但这只限于限制性定语从句中,在非限制性定语从句中,关系词则不可省略。

always(100%)>usually(80%)>often(60%)>sometimes(40%)>seldom(20%)>hardly (10%)>never(0%)
频度副词在句中不同位置的用法比较:
一、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。

三、频度副词位于句首的用法

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。
频度副词的用法:
频度副词是副词的一种,在初中阶段常用的有四个,即always, usually,often,sometimes。它们的用法如下:
一、频度副词在句中的位置。
1.频度副词在句中习惯上位于be动词、助动词之后,行为动词之前。如:
She is often late for school.她上学经常迟到。
He usually goes to bed at about 12.他通常(午夜)十二点钟睡觉。
When do you usually get up in the morning?早上你通常什么时候起床?
2.sometimes是个特殊的频度副词,既可以放在be动词、助动词之后,行为动词之前,也可以放在句首,还可以放在句尾。如:
I sometimes think that it is a great mistake.我有时想这是一个大错。
Sometimes I help my mother in the house.有时候我帮助妈妈做家务。
3.often可以放在句中,也可放在句尾,习惯上不放在句首。如:
We have been there quite often.我们经常到那儿去。
She writes to me often. 她经常给我写信。
4.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。
5.这些频度副词的位置与句中谓语动词有无助动词有关。句中没有助动词时,副词置于动词be之后,其它动词之前。
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。”
6.频度副词后的动词可以是动词的任何形式,具体什么形式和频度副词本身没有关系。
如:
I have never been to the moon.
He sometimes goes to school by bike.
二、表示频度方面的区别:
1.always是频度最大的词,意为"总是;永远"。如:
I shall always remember my first day at school.我将永远记住我上学的第一天。
2.usually意为"通常",即很少例外,频度仅次于always。如:
What do you usually have for breakfast?你通常早餐吃什么?
3.often意为"经常",在频度上不如usually那么频繁。如:
Li Ping often does his homework in the afternoon.李平经常在下午做作业。
4.sometimes意为"有时候",频度比often小,表示动作偶尔发生,间断较大。如:
1.I sometimes go to the library.我有时去图书馆。
2.Sometimes I read a book in the evening.我有时在晚上看书。
三、频度副词与not连用时,表示部分否定;对频度副词进行提问时,要用how often。如:
1.A great scholar is not always a very wise man.大学者未必一定是极聪明的人。
2.We go to the cinema sometimes.(对划线部分提问)
How often do you go to the cinema?
