基本连词
基本的并列连词一共有3个:and、or和but.此种并列连词可以连接对等的单词、短语和句子。
单词:He and I enjoy singing.
Is he happy or sad?
短语:I came to see him and to tell him the truth.
Does he work in Taipei or in Shanghai.
句子:He works hard,and his father is proud of him.
He doesn’t study hard, but his teacher likes him.
基本连词衍生的其他连词
And、or和but衍生的连词
And
both .. and .....两者都
Or
either...or...
要么..要么...
neither..nor...
既不..也不..
But
Not only ... but also ..
不..而且...
not...but... .
并不.而....
使用这些衍生词要注意一下事项:
① 连接主语时,both… and …之后始终接复数动词,其余衍生连词连接主语时,动词要随最近的主语做单复数变化。
例1:Both he and I are happy about it.
例2:Either he or I am wrong.
例3:Neither you nor he is to blame.
② both… and…/neither…nor…/not…but…等三组连词通常不连接句子,而not only…but also…可以用来连接句子,但not only引导的句子要采用倒装结构。
例:Not only can she sing, but she can also dance.(注意是第一分句倒,后面第二分句不倒)
③ not only…but also…中的also通常可以省略。若不省略吗,连接单词或短语时 but also不能分开,连接句子时要分开。
例:
连接单词:She is not only beautiful but(also)kind.
连接句子:Not only can she dance, but she can (also) sing.
as well as(以及…)与rather than (而不是…)做并列连词。可连接对等的单词、短语和句子。
例:We as well as John like it
He came here to learn English as well as to know more about life
注意:
As well as和rather than连接主语时,动词要始终随
第一个主语做变化
He as well as I is interested in music
= He no less than I is interested in music
= He together with me is interested in music
= He along with me is interested in music
他和我都对音乐感兴趣
副词连词
在主从复合句中,由because、if等引导的从句充当状语,类似副词的功能,所以把这类连词称为副词连词。
常用的副词连词有:because、though、if、unless、as soon as和once。具有以下特点:
① 副词连词冠于任何一个从句前,该从句就成为状语从句。整个状语从句可视为副词,用来修饰主句,不能单独存在。
例:I like him. Because he is nice. (错)
I like him because he is nice. (对)
② 副词连词只能连接从句。
例:When he came,I was writing a letter.
③ 状语从句的位置。任何一个副词连词所引导的从句若置于主句之后,两句之间通常没有逗号,但若状语从句置于主句之前,两句之间通常要加逗号。
注意
When(当)、if(如果)、once(一旦)、as soon as(一旦)和unless等副词连接所引导的从句,也可表示一种条件,形成所谓的条件句。若用来表示将来的状况时,条件句的时态要用一般现在时或现在完成时,主句时态用将来时。
例:When I am rich, I will buy a car.
If he has time, he will come here.
连接性副词
此类副词有连接的意味,但不能作为连词来用,此类副词称为连接性副词。这类词有however、nevertheless、therefore、thus、moreover、furthermore和besides等。此类副词在使用时,通常要和主从句隔开。
例:He is nice; however, I don’t like him
He is kind. Therefore, we all like him
