英语连词的用法
As
一.As 用作连词的用法:
1. as用作连词引导时间状语从句
①as与when,while都是引导时间状语从句的从属连词,含义都是"当??的时候"。但它们有区别:用when时,从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生;用while时,从句的动作为一过程,主句动作与从句动作同时进行或在从句动作过程中发生;用as时,主句和从句的动作同时发生,具有延续的含义。例如:
(1)It was snowing when he arrived at the construction site.他到达工地时,天正在下雪。
(2)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。 ②when作"当??的时候"解,可以指较短的(一点)时间,也可指一段时间。如: When he was at college, he could speak several foreign languages.
When the clock struck twelve, all the lights in the street went out. ③while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:
Work while you work. Play while you play.
④但属下列情形时,只用as, 而不用when或while。
A) 用于表示同一个人的两种动作交替进行,指"一边??,一边??"。如:
The girl dances as she sings on the stage.
He looked behind from time to time as he went forward.
B)表示两个同步发展的动作或行为,译为"随着??"。如:
As time went on / by, she became more and more worried.
As children get older, they become more and more interested in the things around them.
C)表示两个短促行为或动作几乎同时发生。如:
I thought of it just as you opened your mouth.
Just as the flying worm hit her face, she g*e a loud cry.
D) 后接名词表示某一年龄段时,用as。如:
As a young man, he was active in sports.
2. as用作连词引导原因状语从句
①as,because,since都可以表示因果关系,连接原因状语从句,含义是"因为,由于",但它们有区别:because表示的语气最强;as一般放在句首,语气较弱,较口语化;since常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因。例如:
(1) He will succeed because he is in earnest.他一定会成功,因为他很认真。
(2) Since you are so sure of it he’ll believe you.既然你对此如此有把握,他会相信你的。
(3) As rain has fallen, the air is cooler.因为下过雨,空气比较清爽。 ②as=since, 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由。如:
As / Since you're not feeling well, you may stay at dangerour place. As/Since he wasn't ready in time, we went without him.
3. as作连词引导让步状语从句
as与although (或though),however (或no matter how)等都可以引导让步状语从句,含义是"虽然,尽管",但它们有区别:although语气稍正式些,可放在句首,也可放在句中,主句中不能再用but,但可以用yet;as所表示的语气较强,引导的让步状语从句用倒装语序,即adj. /adv. / n.+ as +主语+谓语+主句;however引导让步状语从句时,它的后面可跟形容词或副词,也要用倒装语序。例如:
(1) Although he is quite old, he still jogs every day.他虽然年纪相当大,仍然每天慢跑。
(2) Strange as it may seem, nobody was injured in the accident.这次意外虽然显得令人不可思议,却没有人受伤。
Tired as they were, they walked on.
Child as he is, he knows a lot. (child前不用冠词)
(3) However hard he may try, he will not attain his goal.无论他怎样努力也达不到目标。
4.As作连词引导方式状语从句
As=in the way that, 作"像"、"按照??的方式"解,引导方式状语从句。如:
He speaks English as Americans do.
Remember, you must do everything as I do.
5. as...as的用法
as...as意为"和??一样",表示同级的比较。使用时要注意第一个as为副词,第二个as为连词。其基本结构为:as+ adj./ adv. +as。
例如:
(1)This film is as interesting as that one.这部电影和那部电影一样有趣。
(2)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。 其否定式为not as/so +adj./ adv. +as。例如:
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
若有修饰成分,如twice, three times, half, a quarter等,则须置于第一个as之前。例如:
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
用于as...as...或not so/ as...as...中,引导比较状语从句。如:
They helped the old man as often as possible.
I don't speak English so/ as well as he does.
几个关于as...as的常见句型:
(1)as...as possible
Please answer my question as soon as possible.请尽快回答我的问题。
(2)as...as usual/before
She looks as pretty as before.她看起来和以前一样漂亮。
(3)as long as... (引导条件状语从句)
It took us as long as three years to carry out the plan.我们花了长达三年的时间才完成这项计划。
(4)as far as
He walked as far as the railway station yesterday evening.昨天傍晚,他一直散步到火车站。
(5)as well as
She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。
一些带有as...as结构的常见短语归纳:
as busy as a bee像蜜蜂一样忙碌
as easy as ABC像ABC一样容易
as deep as a well像井一样深
as light as a feather像羽毛一样轻
as soft as butter像黄油一样软
as rich as a Jew像犹太人一样富裕
二、as作关系代词的用法
关系代词as引导定语从句时,既可以单独使用,也可以与其他词连用,其用法要比that和which更为复杂。
1. as引导定语从句与其他词连用
①用于the same...as结构中
This is the same book as I read last week.这本书和我上周读的那本是一样的。 I was reading the same book as he bought yesterday.
②用于such...as结构中
I don’t like such books as he recommends.我不喜欢他推荐的那些书。
Such a clever boy as he can learn anything quickly.
③用于"so +adj. + a/an + n. (单数) + as "结构中
I am not so strong a man as I was.我已经没有从前那么强壮了。
2. as单独引导定语从句
①as单独引导定语从句时,先行词可以是一个词,也可以是一个句子或短语。例如:
(1) She is late, as is often the case.她迟到了,这是经常的事。(先行词是整个主句)
(2) To shut your eyes to facts, as many of you do, is foolish.对事实视而不见---你们好多人都是如此的愚蠢。(先行词是不定式短语)
②as作关系代词,引导定语从句,作"正如"、"这一点"解。如:
He is very careful, as his work shows.
As is well-known, Taiwan belongs to China.
As is known to everybody, the moon travels round the earth once every month.
三、as作介词的用法
①as作介词,意思是"作为","以??身份"。例如:
He came to China as a tourist five years ago.他五年前以游客的身份来过中国。 As a League member, I'll take the lead in everything. (状语)
She works as a doctor. (状语)
②少数情况可引起宾语补足语。如:
They have me as one of their own children.(引起宾语补足语)
四、as作副词的用法
to the same degree or amount; equally "相同地","同样地"。例如:
They don’t have as many airplanes.他们没有同样多的飞机。
For
用法1:(表目的)为了。如:
They went out for a walk. 他们出去散步了。
What did you do that for? 你干吗这样做?
That’s what we’re here for. 这正是我们来的目的。
What’s she gone for this time? 她这次去干什么去了?
He was waiting for the bus. 他在等公共汽车。
【用法说明】
通常,英语不用 for doing sth 来表示目的。如:
他去那儿看他叔叔。
误:He went there for seeing his uncle.
正:He went there to see his uncle.
但是,若一个动名词已名词化,则可与 for 连用表目的。如:
He went there for swimming. 他去那儿游泳。(swimming 已名词化)
注意:若不是表目的,而是表原因、用途等,则其后可接动名词。(见下面的有关用法) 用法2:(表利益)为,为了。如:
What can I do for you? 你想要我什么?
We study hard for our motherland. 我们为祖国努力学习。
Would you please carry this for me? 请你替我提这个东西好吗?
Do more exercise for the good of your health. 为了健康你要多运动。
【用法说明】
(1) 有些后接双宾语的动词(如 buy, choose, cook, fetch, find, get, order, prepare, sing, spare 等),当双宾语易位时,通常用 for 来引出间接宾语,表示间接宾语为受益者。如:
She made her daughter a dress. / She made a dress for her daughter. 她为她女儿做了件连衣裙。
He cooked us some potatoes. / He cooked some potatoes for us. 他为我们煮了些土豆。
注意,类似下面这样的句子必须用 for:
He bought a new chair for the office. 他为办公室买了张新办公椅。
(2) 注意不要按汉语字面意思,在一些及物动词后误加介词 for:
他们决定在电视上为他们的新产品打广告。
误:They decided to advertise for their new product on TV.
正:They decided to advertise their new product on TV.
注:advertise 可用作及物或不及物动词,但含义不同:advertise sth=为卖出某物而打广告;advertise for sth=为寻找某物而打广告。如:advertise for a job=登广告求职。由于受汉语“为”的影响,而此处误加了介词 for。类似地,汉语中的“为人民服务”,说成英语是 serve the people,而不是 serve for the people,“为某人的死报仇”,说成英语是 avenge sb’s death,而不是 avenge for sb’s death,等等。
用法3:(表用途)用于,用来。如:
Knives are used for cutting things. 小刀是用来切东西的。
This knife is for cutting bread. 这把小刀是用于切面包的。
It’s a machine for slicing bread. 这是切面包的机器。
The doctor gave her some medicine for her cold. 医生给了她一些感冒药。
用法4:为得到,为拿到,为取得。如:
He went home for his book. 他回家拿书。
He went to his friend for advice. 他去向朋友请教。
She often asked her parents for money. 她经常向父母要钱。
We all hope for success. 我们都盼望成功。

用法5:给(某人),供(某人)用。如:
That’s for you. 这是给你的。
Here is a letter for you. 这是你的信。
Have you room for me there? 你那边能给我腾出点地方吗?
用法6:(表原因、理由)因为,由于。如:
I am sorry for it. 对不起。
Thank you for coming to see me. 谢谢你来看我。
You can’t see the wood for the trees. 你只见树木,不见森林。
He is famous for his poems. 他因为他的诗出名。
He was sent to prison for robbery. 他因为抢劫而坐牢。
I couldn’t speak for laughing. 我笑得说不出话来。
He couldn’t sleep for joy. 他高兴得不能入睡。
For several reasons, I’d rather not meet her. 由于种种原因,我宁愿不见她。
【用法说明】有些表原因的特殊结构不宜用介词 for 来引出,而用其他介词。如: 他由于努力工作而加了工资。
误:For the result of his hard work, he got a pay rise.
正:As a [the] result of his hard work, he got a pay rise.
注:as a [the] result of 是习语,意为“由于??的结果”。
因为母亲不在家,她只好自己做饭。
误:For Mother (being) away, she had to cook the meal herself.
正:With Mother (being) away, she had to cook the meal herself.
注:“with+宾语+宾语补足语”可用来表示原因,此时的 with 不能换成 for。类似地,下例中的 with 也不能换成 for:
With all this work to do, I don’t know if I’ll have time to go out. 有这么多工作要做,我不知是否有时间出去。
我们祝贺你的成功。
误:We congratulate you for your success.
正:We congratulate you on your success.
注:congratulate 后习惯上接介词 on 表示原因。
用法7:(表目标、去向)去。如:
Is this bus for Chicago? 这辆公共汽车开往芝加哥吗?
They’ll leave for Beijing tomorrow. 明天他们动身去北京。
They set off for the shops. 他们买东西去了。
Is this the train for Shanghai? 这是开往上海的火车吗?
Passengers for Tianjing must change at Beijing. 去天津的旅客必须在北京换车。
【用法说明】比较 for 与 to,两者均可表示目的地,注意以下区别:
for 通常与 leave, start, set out, set off, head, steer, depart, be bound, be destined 等动词连用,而 to 则通常与 come, drive, fly, get, go, lead, march, move, return, ride, run, travel, walk 等动词连用。如:
We departed for London at 10 am. 我们上午10点动身去伦敦。
Then we drove to the station. 然后我们就开车去了车站。
有时,同一个动词(如 sail)两者均可连用,但含义稍有差别:用 for 通常只表示向着某目的地那个方向,并不强调到达的意思;而 to 含有到达某目的地的意思。如:
They sailed for Shanghai. 他们开船驶往广州。
They sailed to Shanghai. 他们开船驶至广州。
若与名词连用,也有类似区别。如:
There will be a train for Wuhan. 有开往武汉的火车。(仅表示向武汉方向,但在武汉未必是停靠站)
There will be a train to Wuhan. 有开往武汉的火车。(开往武汉方向,且在武汉停靠)
顺便说一句,也有的辞书持几乎相反的观点,认为 for 与 to 表示目的地时,for 表示的是预定目的地,而to 表示的是假设将会到达的目的地。
用法8:(表时间、距离、数量等)达,计。如:
I’m going away for a few days. 我要走开几天。
I’ve been here for ten years. 我来这儿有10年了。
He walked for ten miles. 他走了10英里路。
The shop sent me a bill for $50. 商店给我送来了一张50美元的账单。
【用法说明】for 用于表示时间或距离的长度(尤其是紧跟在动词之后)时,有时可省略。如:
The meeting lasted (for) three days. 会议持续了3天。
They walked (for) fifty miles. 他们走了50英里。但是当 for 短语位于句首或在否定句中时, for 通常不宜省去。如:
For ten years he lived here. 他在这里住过10年。
We have not heard from him for a long time. 我们很久没收到他的来信了。
用法9:对,对于。如:
Eggs are good for you. 鸡蛋对你有好处。
Reading in bed is bad for your eyes. 躺在床上看书对你的眼睛不好。
Fortunately for me, the train was also late. 我很走运,火车也晚点了。
【用法说明】关于 for 与 to 表示“对??来说”时的区别,参见 to。
用法10:(表适合)适于,适合。如:

I bought a pound of apples for 70 cents. 我花了七角钱买了一磅苹果。

He knew that for a fact. 他知道那是事实。
The missing persons were given up for dead. 大家都认为那些失踪的人已死了。
【用法说明】用于此义时,有时相当于 as, to be, as being,但要注意不同句型的搭配习惯。如:
I took him for an honest man. / I took him to be honest. 我看他为人老实。 It was built for [as] a pleasure boat. 这船建作游艇之用。
比较:
He took her smile for agreement. 他把她的微笑视为同意。
Will you take me as your partner? 你把我看作你的合伙人好吗?
按传统语法,take?for? 通常指误认为是??,而 take?as [to be] 则主要指正确地认为是??。但在现代英语中,有时并未完全遵守此规则。
但是与 mistake 连用的则通常是 for 而不是 as。如:
We mistook the house for a hotel. 我们把那房子误以为旅馆。
用法13:(表支持、赞成)支持,赞成。如:
Are you for or against the plan?你是支持还是反对这个计划?
I’m all for the young enjoying themselves. 我完全赞成年轻人多玩玩。
用法14:(表基准)就??来说,以??而言,作为。如:

【用法说明】用于此义时,通常与 each, every 或数词连用。

What’s the “C” for in “BBC”? BBC中的C代表什么?
Red is for danger. 红色代表危险。
Let me do it for you. 让我替你做吧。

The appointment is for 10:30. 约会定在十点半。
We’ve invited our guests for 7 o’clock. 我们已邀请我们的客人7点钟来。 We’ve booked our holiday for the second week in July. 我们的假期安排在七月份的第二个星期。
The next meeting was arranged for the tenth of May. 下次会议已定于5月10日举行。
【用法说明】用于此义时,for 主要指安排或约定的时间,所以像下面两例中的介词 at,in 就不能换成 for。如:
He gets up at six every day. 他每天6点钟起床。
He was born in September, 1988. 他出生于1988年9月。
用法18:(表让步)尽管,虽然。如:

【用法说明】
(1) 下面两句同义,但以第一句为普通。如:
老人快跑是危险的。
正:It is dangerous for an old man to run fast.
正:For an old man to run fast is dangerous.
(2) 有时可表目的。如:
I’ve sent my coat away for it to be cleaned. 我把外衣送去洗了。
For sales to increase, we must lower our prices. 为了增加销量,我们必须降低价格。
(3) 有时用于 than 后引出不定式的逻辑主语。如:

链接of的用法
1. 表示\"属于关系\",意为\"(属于)......的\"。如:the leaves of the tree
2. 表示\"(关于)......的\"。如:stories of Lei Feng, a map of China

IF
一、if作为连词,引导条件状语从句。它表示的意思是“假如”“如果”等。在复合句中如果主句用将来时,则if引导的状语从句用一般现在时。例如:
1. If itdoesn’train, we will go to the park next Sunday. 如果天不下雨,下周星期天我们将去公园。
2. If you ask him,he will help you.如果你求他,他将会帮助你。
二、if还可以引导让步状语从句。这时if当作“即使是”,“虽说”解。例如:
1. If she’s poor,at least she’s honest. 虽说她很穷,但至少她还是诚实的。
2. If I am wrong,you are wrong, too. 即使说我错了,那么你也不对。
3. I’ll do it, even if it takes me all the afternoon. 虽然会花费我一下午的时间,我还是要做这事。
三、if作为连词还可以引导宾语从句。引导宾语从句时和whether意思相同。例如:
1. Lily asked if / whether she liked it. 莉莉问她是否喜欢它。
2. She asked if / whether they had a cotton one. 她问是否他们有一件棉织的。
四、if引导时间状语从句。当if做“当”或“无论何时”解而不含有条件之义时,if从句中的时态与主句中的时态相同。例如:
1. If youmix yellow and blue,you get green.你将黄色与蓝色混合,便会得到绿色。
2. If she wants the servant,she rings the bell.每当她需要仆人时,她便按铃。
五、if后接否定动词,用于感叹句中,表示沮丧、惊奇等。例如:
I. Well,if I haven’t left my false teeth at home!真倒霉,我把假牙丢在家里了!
2. And if he didn’t try to knock me down!(What do you think he did!He tried knock me down!)你猜他想做什么?他想把我撞倒!
六、用于虚拟语气中。if从句中用过去式,表示不可能实现,大概不会实现或提出作为考虑的假定条件。例如:
1. If you were a bird, you could fly.假使你是只鸟,你便会飞了。
2. If I asked him(if I were to ask him) for a loan,would he agree?如果我向他借贷,他会答应吗?
另外,if从句中用过去完成式,表示过去未实现的条件(例如由于不可能实现或某人之未能实行)。例如:
1. If they had startedearlier,they would have arrivedin time.要是他们早些动身,他们便可及时到达了。
2. If they had not started when they did,they would not be here now.如果他们那时不动身,现在他们就不会在此地了。
第三,在文学体栽中,if有时可省略,然后将主语与所用的限定动词(尤其是were,had,should)倒置。例如:
1. Should it (=if it should)be necessary,I will go. 倘若有必要,我会去的。
2. Were I(=if I were) in your place,I would do the same . 如果我处于你的位置,我也会这样干的。
3. Had I(=if I had)known earlier,I would come.如果我早一点知道,我就会来。
七、if与其它一些介词的连用。
首先,as与if连用,它的意思是:“仿佛、好像”同样引导从句。例如:
1. It isn’t as if we are rich.(We are not rich.)我们不像富有的样子。(即我们不富有)
2. It isn’t as if he doesn’t know the ruler.(i.e.He does know the rulers.)他不像不懂规则的样子。(即他懂得规则)
另外as if还可以引导感叹句。例如:
As if I would allow it!(i.e.I would certainly not allow it!)好像我会答应似的!(我才不会答应哩!)
其次, if与only连用。常表示愿望或一个未实现的条件,尤其用于感叹句中。例如:
1. If only he arrives in time!他若能及时到达就好了!
2. If only she would marry me!但愿她能嫁给我!
3. If only she had known about it!(But she didn’t know.) 她那时要是知道(但她不知道)这事就好了!
HOWEVER
1. 用作副词
(1) 表示让步:意为 “无论如何”“不管怎样”,用来修饰形容词或副词,其词序为:however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能,用以引导让步状语从句。如:
Phone me when you arrive, however late it is. 你到达之后就给我打电话,不论多么晚也要打。
However much he eats, he never gets fat. 不管他吃多少,他永远吃不胖。
However cold it is, he always goes swimming. 不管天有多冷,他都去游泳。 You won’t move the stone, however strong you are. 不管你力气有多大,也休想搬动那块石头。
However far it is, l intend to drive there tonight 不管有多远,我今晚也要开车到那儿去。
用于此用法时,请注意以下几点:
①此用法属however所有用法中最重要的考点,同学们务请引起高度重视。
②这样用的 however与 no matter how 大致同义。如:
People always want more, however [no matter how] rich they are. 人总是富了还想再富。
However [No matter how] hard I worked, she was never satisfied. 无论我多么努力地工作,她从来没满意过。
③有时从句谓语可用情态动词。如:
Don’t laugh, however funny it may be. 无论多么有趣也不要笑。
I’ll try to finish it in time, however hard it may be. 无论多么难,我也要按时完成。
④“however+形容词或副词+主语+谓语”有时可以有所省略。如:
I refuse, however favorable the conditions. 不管条件如何有利,我都不干。(conditions后省去了are)
I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小,我宁愿一个人住一间,而不愿意与别人合住一个房间。
A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则,不管如何正确,除非能懂,否则毫无用处。
(2) 表示转折:尤其用于谈及一个既成事实时,表示转折,其意为“可是”“仍然”等。可放在句首、句中或句末,通常用逗号与句子其他成分隔开。如:
My father, however, did not agree. 但是,我父亲不同意。
My room is small; however, it’s comfortable. 我的房间很小,但却很舒服。 My room is small; however, it’s comfortable. He said that it was so; he was mistaken, however. 他说情况如此,可是他错了。
注:however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)注意正句中的标点符号。如:
我们都已尽了最大的努力,不过我们还是输了。
误:We all tried our best, however we lost the game.
正:We all tried our best, but we lost the game.
正:We all tried our best; however, we lost the game.
正:We all tried our best. However, we lost the game.
(3) 表示惊奇或强调:相当于how ever的用法,其意为“究竟怎样,到底以什么方式”。如:
However did you get here without a car? 没有汽车你究竟是怎样来的呢? 没有汽车你究竟是怎样来的呢
However does he manage to write music when he is so deaf? 他聋成这个样子,究竟是怎样从事作曲的呢?
2. 用作连词。
用作连词引导方式状语从句,表示“无论以何种方式“”“不管怎样”。如:
However it may be, I shall take your word. 无论如何,我将会相信你的话。 However I approached the problem, I couldn’t find a solution. 这一问题我不管怎样都无法解决。
However you travel, it’ll take you at least two days. 无论你怎么个走法,至少要两天时间。
However you travel, /SPAN>The painting looks wrong however you look at it. 这张画不论怎么看都显得不对劲。
NEITHER EITHER比较
1. neither意为“既不是甲,也不是乙”,“两者都不??”,后面跟单数动词的肯定式。它可以单独使用,后面也可跟名词或of+the/these/those/所有格代词或人称代词:
(a)I tried both keys but neither(of them)worked.两把钥匙我都试了,但(两把)都不行。
(b)Neither of them knew the way/Neither boy knew?他们俩/两个男孩都不认得路。
(c) I’ve read neither of these(books).这两本(书)我都没看过。
2 .either意为“两者之一”,“两者中任何一个”。它后面跟动词单数形式。同neither一样,它可以单独使用,或跟名词/代词及of+the/these/those等连用。
3.either+否定动词可代替neither+肯定动词,但neither是主语时除外。所以either不能用于上面Al例句(a)或(b)中,只能用于例句(c)中:
I haven’t read either of these(books).这两本(书)我都没看过。 虽然either不能作否定句的主语,但它可作肯定句或疑问句的主语或宾语: Either(of these)would do.这两个中任一个都可以。
Would you like either of these?你喜欢二者中的任一个吗?
4.代词和所有格形容词与代表人的neither/either连用时,从语法上说应当用he/him,she/her及his/her,但是在英语的口语中用复数形式较为普遍:
Neither of them knows the way,do they?他们俩都不知道路,是吗?
Neither of them had brought their passports.他们俩都没带护照。
5.neither?nor,either? or neither? nor+肯定动词是把两个否定说法结合在一起的强调方式:
(a)Neither threats nor arguments had any affect on him.无论是恐吓还是讲道理对他都不起作用。
(b)They said the room was large and bright but it was neither large norbright.他们说这间房子又大又明亮,可它既不大也不明亮。
(c)He neither wrote nor phoned.他既没写信又没打电话。
6.either?or+否定动词可代替neither?nor+肯定动词结构,但neither?nor作动词主语时除外,如上述例句(a)。所以可以说:
(b)?but it wasn’t either large or bright.
(c)He didn’t either write or phone.
either?or不能作否定句的主语,但可作肯定句和疑问句的主语或宾语。这种用法是表示强调二者之中任何一个皆可以:
You can have either soup or fruit juice.汤和果汁你任意喝哪一种都行。
You must either go at once or wait till tomorrow.你要么马上走,要么等到明天。
It’s urgent,so could you either phone or telex?这事非常紧急,所以你或是打电话或是用电传,好吗?

范文五:英语连词用法
英语连词用法
话题:连词 两个 教育学习
1. 并列连词与并列结构并列连词引导两个并列的句
子。1) and 与or判断改错:(错) They sat down and talk about something.(错) They started to dance and sang.(错) I saw two
men sitting behind and whisper there.(对) They sat down and
talked about something.(对) They started to dance and sing.(对)I
saw two men sitting behind and whispering there.解析:第一句:
and 连接两个并列的谓语,所以 talk 应改为 talked。第二句:
and 连接两个并列的动词不定式,第二个不定式往往省略to,
因此sang 应改为 sing。第三句:and 连接感观动词saw 后
面的用作的宾补的两个并列分词结构,因此whisper应改为
whispering。注意:and 还可以和祈使句或名词词组连用表示
条件。(or也有此用法)Make up your mind, and
you´ll get the chance.= If you make up your mind,
you´ll get the chance.One more effort, and you´ll succeed.= If you make one more effort, you´ll succeed.2) both …and 两者都She plays
(both) the piano and the guitar.3) not only…but (also), as well as不但…而且)She plays not only the piano, but (also) the guitar.注意: not only… but also 关联两个分句时,一个分句
因有否定词not 而必须倒装。Not only does he like reading stories, but also he can even write some.4) neithe…nor 意思
为”既不……也不……”谓语动词采用就近原则,与nor后的
词保持一致。Neither you nor he is to blame.2 比较and和or1)
并列结构中,or通常用于否定句,and用于肯定句。2) 但有
时and 也可用于否定句。请注意其不同特点:There is no air
or water in the moon.There is no air and no water on the moon.在否定中并列结构用or 连接,但含有两个否定词的句子实
际被看作是肯定结构,因此要用and。典型例题---I
don´t like chicken ___ fish.---I don´t like chicken, ___ I like fish very much.A. and; and B. and;
but C. or; but D. or;and答案C。否定句中表并列用or,
but 表转折。判断改错:(错) We will die without air and water.(错) We can´t live without air or water.(对)
We will die without air or water.(对) We can´t live
without air and water.3 表示选择的并列结构1) or 意思为”
否则”。I must work hard, or I´ll fail in the exam.2) either…or 意思为”或者……或者……”。注意谓语动词采用
就近原则。Either you or I am right.4 表示转折或对比1) but
表示转折,while表示对比。Some people love cats, while others hate them.典型例题--- Would you like to come to dinner tonight?--- I´d like to, ___ I´m too busy.A. and B. so C. as D. but答案D。but与前面形
成转折,符合语意。而表并列的and, 结果的so,原因的
as都不符合句意。2) not…but… 意思为”不是……而
是……”not 和but 后面的用词要遵循一致原则。They were
not the bones of an animal, but (the bones) of a human being.5 表原因关系1) for判断改错:(错) For he is ill, he is absent
today.(对) He is absent today, for he is ill.for是并列连词,不能
置于含两个并列分句的句子的句首,只能将其放在两个分句
中间。2) so, thereforeHe hurt his leg, so he couldn´t play in the game.注意:a. 两个并列连词不能连用,但therefore,
then, yet.可以和并列连词连用。You can watch TV, and or you
can go to bed.He hurt his leg, and so / and therefore he couldn´t play in the game.b. although… yet…,但
although不与 but连用。(错) Although he was weak, but he
tried his best to do the work..(对) Although he was weak, yet
he tried his best to do the work.6 比较so和 such其规律由so
与such的不同词性决定。such 是形容词,修饰名词或名词
词组,so是副词,只能修饰形容词或副词。so 还可与表示
数量的形容词many,few,much, little连用,形成固定搭
配。so + adj. such + a(n) + n.so + adj. + a(n) + n. such + n. (pl.)so + adj. + n. (pl.) such +n.
(pl.)so + adj. + n. [不可数] such +n. [不可数]so foolish such a foolso nice a flower such a nice flowerso many/ few flowers such nice flowersso much/little money. such rapid progressso many people
such a lot of peopleso many 已成固定搭配,a lot of 虽相当于
many,但 a lot of 为名词性的,只能用such搭配。so…that
与such…that之间的转换既为 so与such之间的转换。
