专题六—连词
连词就是把两个或两个以上相关的单句组合起来的词语。连词用来连接词、短语、从句或句子,是一种虚词,不能单独作句子成分;连词可以使句子与句子联络比较紧凑,因此使上下文更加连接。
连词的分类
1.连词从本身含义及所连接的语言单位之间的逻辑关系,可分为并列连词和从属连词。
并列连词是用来连接彼此并列的词、短语、从句或句子的词,常用的有and, or, but, for, therefore, not only...but also 等。从属连词通常引导名词性从句即主语从句、宾语从句、表语从句、同位语从句(that, whether, if 等)以及状语从句(when, while, though, because, if, so that等 )。
2.连词从句子构造形式上分为:
简单连词:and, but, when, for, if, while等。关联连词:both ... and, neither ... nor, as...as 等。
短语连词:as if, so that等。分词连词:given, considering, supposing等。
考点一—并列连词
并列连词可表示多种意义,但主要有四种,即表示并列、转折、选择、因果等。
一、并列连词and/but/or/so的用法(9AUnit1---GrammarA)。
一.) and、or、 but、 so 的基本用法:
★and: ①表并列关系:“和、并且、又”;(and 在否定句中改为or)。e.g.:
Daniel is modest and never shows off.
I am active and energetic,and I love working with people.
②用于祈使句,表结果,and 通常是比较好的结果。e.g.:
Try your best,and you’ll make more progress.
★but:表转折关系:“但是”;(不能和(al)though同时使用)。(al)though用于表示原因的句子前,but用于表示结果的句子前。e.g.:
◆ Although/Though I have passed the exam, I am not pleased with the result.
=I have passed the exam, but I am not pleased with the result.
◆ He doesn't like to talk much, but his work shouts.
= Although/Though he doesn't like to talk much, his work shouts.
★or: ①表选择关系:“或者”; e.g.:
I can be a good teacher or a good doctor.
Which do you like better, apples or pears
②表并列关系:“和、并且、又”;在否定句中or表并列关系。 e.g.:
He does not like singing or dancing.
③用于祈使句,表结果,or通常表示不愉快或不理想的结果:“否则,要不然(=otherwise)”。e.g.:Get up quickly, or you’ll be late.
Study hard, or you won’t pass the exam.
Don’t lose heart, or you’ll lose all.
★so: 表因果关系:“因此、所以”;(不能和because同时用)。because用于表示原因的句子前,so用于表示结果的句子前。e.g.:
I want to share the best art with people, so I am always searching for something better or different.
It began to rain, so we went home.=Because it began to rain, we went home.
二.)and、or、 but、 so 的特殊用法:
(一)同义句改写:
◆ Study hard, and you can get good grades.
=If you study hard, you can get good grades.
=If you don’t study hard, you cannot get good grades.
◆Get up quickly, or you’ll be late.
=If you get up quickly, you’ll not be late.
=If you don’t get up quickly, you’ll be late.
(二)and连接主语时,谓语动词要灵活运用。
1.Bread and butter is his favourite food.
Bread and butter看作整体主语,谓语动词用单数。类似的还有knife and fork; lightning and thunder; the bow and arrow等。
2.The chairman and host of the meeting comes from/is from the USA.
(会议主席兼主持人是一个人。)
The chairman and the host of the meeting come from/are from the USA.
(会议主席和主持人是不同的两个人。)
3.Every boy and every girl is fond of the film.
(三)“so + be 动词/情态动词/助动词+主语”(某人也是)。
◆表示前一句中主语的肯定情况也适用于后者,在时态上应和前一句保持一致,但两句的主语应是不同的两人。例如:.
① “ He is a Chinese.” “ So am I.”
② “Tom can dance.” “ So can Mary.”
③ “Mother will go to Beijing.” “So will I.”
④ I have been to America. So has Li Lei.
⑤ She likes English. So do they.
⑥ Lily played basket yesterday. So did Lucy.
小小诊所:
so前面的句子都是肯定句。若前面的句子是否定句,那就不能用so引导这个句子了,而应该用“Neither/Nor + be 动词/情态动词/助动词+主语”(某人也不)。
◆“Neither/Nor + be 动词/情态动词/助动词+主语” (某人也不)
表示前一句中主语的否定情况也适用于后者,前后两句的主语是不同的。
“He isn’t a Chinese.” “Neither am I.”
Tom can’t dance.” “Neither can Mary.”
Mother won’t go to Beijing. “Neither will I.”
I haven’t been to America. Neither has Li Lei.
She doesn’t like English. Neither do they.
--- Lily didn’t play basketball yesterday. --- Neither did Lucy.
⑦ “I don’t like playing with that girl.” “Neither does he.”
◆“so +主语+ be 动词/情态动词/助动词”(的确如此)。当两句中的主语是同一人时,译成“的确如此”,句序不用倒装。
① ---It’s a bad day today. ---So it is.
---John studies English well. ---So he does.
(四)A or B 和 not A but B 结构作主语时,谓语动词要使用就近原则。
1. He or the twins come from the USA.
2. Not Tom but I am going to give the talk.
二、并列连词as well as的用法
as well as 起连词作用,表示“同、和、也”等。
The editors as well as the proofreaders are working overtime.编辑和校对者都在加班工作。
I have read his novels as well as his plays.我读过他的小说和剧本。并列连词 when的用法
三、并列连词when的用法
when 作为并列连词,意为“就在那时”。
I was about to leave when the telephone rang.我刚想走,突然铃响了。
We played outside till sunset, when it began to rain.我们在户外一直玩到太阳下山,那时天下起雨来了。
四、并列连词both ... and ...,not only ... but (also) ..., either ... or ... neither ... nor ...的用法。
both ... and ...、not only ... but (also) ...、either ... or ... 和neither ... nor ...都是常见的并列连词,它们可以连接两个并列的主语、谓语、宾语、表语、状语等。(9AUnit1---Grammar B)
一、)both ... and ...,not only ... but (also) ..., either ... or ... neither ... nor ...的基本用法。
★both ... and ...意思是“......和......两者都;既......又......”。
I did all this both for you and for myself.(连接两个并列的状语)
Both Li Ping and Wu Fang are League members.(连接两个并列的主语)
★not only ... but (also) ...意思是“不但......而且......;不仅......还有......”,其中also可以省略。
We must not only understand the text but also learn it by heart.(连接两个并列的谓语)
注意:当not only ... but (also) ...连接两个名词作主语时,其谓语动词应与最近的一个主语在人称和数上保持一致,这就是我们通常说的“就近原则”。
Not only the students but (also) Mr Li has lunch at school.(连接两个并列的主语)
★either ... or ...意思是“要么......要么......;或者......或者......;不是......就是......”,用于连接两个表示选择关系的词。
You may sit either this end or that end of the boat.
注意:当either ... or ...连接两个主语时,应遵循“就近原则”。
Either you or I am going there tomorrow.
★neither ... nor ...意思是“既不......也不......”,具有否定含义。
Neither Leo nor Cindy got the highest score. It was Daisy.
注意:当neither ... nor ...连接两个主语时,也应遵循“就近原则”。
Neither Dad nor Mum is at home today.
◆总结:
1、not only…but (also)… “不但...而且...; either…or… “要么...要么...;不是...就是...” neither…nor… “既不......也不......”连接两个并列的主语时谓语动词使用就近一致的原则。
2、否定句中too改为either。
3、Neither可用于倒装句中。
★Add:使用谓语动词“就近原则”的短语还有:
◆A or B:
①He or the twins come from the USA.
②The twins or he comes from the USA.
◆not---but---
①Not Lucy but her parents are searching for something better or different.
②Not her parents but Lucy is searching for something better or different.
知识拓展
◆both
Both可作形容词、代词或副词用,意思是“两个”、“双方”、“两个都”。在句中可作主语、宾语或同位语。如:Both are right.(主语) I like both.(宾语)Both pencils are mine.(同位语)
(一)Both和both of后都可接复数名词,构成名词词组。
1、Both后的名词前可有定冠词、指示代词或物主代词作修饰限定,也可没有;both of后的名词前却一定要有定冠词、指示代词或物主代词作修饰限定。如:
both(the these,her) children√both of the(these,her)children√;both of children×
2、Both of后可接人称代词宾格,both后则不可;但人称代词宾格后可接both。
both of us(you,them)√both us(you,them)×us(you,them)both√
(二)Both在句中的位置。
1、Both与动词连用时,大多数放在系动词be之后,行为动词之前。
His parents are both workers. They both enjoy reading.
2、若句中谓语动词包含情态动词或助动词时,both大多放在第一个情态动词或助动词之后,行为动词之前。如:
The bridges must both be built this year.
Kate and Mary have both gone to England.
(三)Both可与and构成并列连词,连接两个性质相同并在句中作相同成分的并行结构。
Both he and his brother are good at English.(连接两个主语)
She can both dance and sing.她能歌善舞。 (连接两个谓语动词)
Mary is both kind and beautiful.玛丽既友善又漂亮。(连接两个表语)
(四)含both的句子变为否定句的情况。
1、变为否定时,将both改为neither,变成完全否定。如:
Both of the boys are clever.两个男孩都聪明。
▲Both of the boys are not clever.不完全否定。并不是两个男孩都聪明(一个聪明一个愚笨)。
▲Neither of the boys are clever.两个男孩都不聪明。
I don‘t know both his teachers.他的两位老师我并非都认识。(半否定)
I know neither his teachers.他的老师我都不认识。(全否定)
2、含both…and…的句子变为否定句时,将both…and…改为neither…nor..,连接的两个部分若是名词,可以是单数,也可以是复数。
I know both the man and the woman. →I know neither the man nor the woman.
Both beats and birds would have the bat as their friend.
Neither beats nor birds would have the bat as their friend.
◆either
either : 指两者中的任意一个。如:
either side of the street/road=both sides of the street/road
Either of the films is good.
Either you or he has lunch at school. 其一般疑问句应为:
Do either you or he have lunch at school 是你还是他在学校吃午饭?
考点二—从属连词用法
从属连词通常引导名词性从句即主语从句、宾语从句、表语从句、同位语从句(that, whether, if 等)以及状语从句(when, while, though, because, if, so that等 )。
一、引导名词性从句的从属连词有that, whether, if等,它们在句中均不能充当任何句子成分,其中that没有词义,仅起引导从句的作用;whether /if 有词义,两者均表示“是否”。如:
She asked if/ whether he would go to her party 她问他是否要去参加她的晚会。
句中的if引导宾语从句,用作动词 ask 的宾语,if/ whether在此表示“是否”。
The question is whether he has signed the contract. 问题是他是否在合同上签了字
句中的 whether 引导表语从句,表示“是否”的意思。按英语语法习惯,引导表语从句时要用 whether,一般不用if,尽管它们意思是一样的。
Only she remembered that it was my birthday. 只有她记得这天是我的生日。
句中的 that引导宾语从句,用作动词 remember 的宾语,that 在中不表示任何意思,只起连接作用。
二、引导状语从句的从属连词比较多,同时状语从句根据其意义的不同,可以有很多种类型。1.引导时间状语从句的连词有when, while, as, before, after, as soon as, since, until等;
2.条件状语从句的连词通常由if, unless等来引导;
3.表示原因的状语从句叫原因状语从句,它通常由 because, as等来引导。
4.引导让步状语从句的从属连词主要有although, though, even though, even if, while, however, whatever, whoever whenever, wherever等。
Although [Though] he is poor, he is well contented.他虽穷却能知足常乐。
Though [Even though] it’s hard work, I enjoy it.尽管是苦活,但我乐意干。
Even if you don’t like wine, try a glass of this.即使你不喜欢喝酒,也尝尝这杯吧。
While we don't agree we continue to be friends.尽管我们意见不同,但我们还是朋友。
However you use it, it won’t break.不管你怎么使用,它都不会破。
Whatever you say, I believe you.无论你说什么,我都相信你。
Whoever telephones, tell them I’m out.不管是谁打电话,都说我出去了。
Whenever you come, you are welcome.你什么时候来,我们都欢迎。
However much he eats, he never gets fat. 无论他吃多少他都不发胖.
5.引导原因状语从句的从属连词主要有because, as, since, seeing (that),now (that),considering (that)等:He couldn't got to school because he had a cold.他因患感冒而未能去上学。
Since everybody is here. let's begin our discussion.大家都到了,我们就开始。
Seeing that it is 8 o‘clock, we’ll wait no longer.由于时间已到8点,我们将不再等了。

It's so difficult a question that none of us can answer it. 那是一个很难的问题,我们没有一个人能回答。
He shut the window with such force that the glass broke. 他关窗户用力很大,结果玻璃震破了。注: so that 中的that在口语中通常可以省略。
9.引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case等。
If anyone calls, tell them I m not at home要是有人打电话来,就说我不在家。
You will fail unless you work hard.你若不努力就会失败。
As[So] long as you need me, Ill stay. 只要你需要我,我就留下。
In case I forget, please remind me about it. 万一我忘记,请提醒我一下。
注:
在条件状语从句中,通常要用一般现在时表示将来意义,而不能直接使用将来时态。不过,有时表示条件的if之后可能用will,但那不是将来时态,而是表示意愿或委婉的请求(will为情态动词)。
10.引导时间状语从句的从属连词归纳
