英语语法笔记第10期——并列连词和连接性副词

这一期我们讲并列连词和连接性副词。
1、 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:heand i enjoy singing.
is he happyor 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.
2、 基本连词衍生的其他连词。

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 arehappy about it.
例2:either he or i am wrong.
例3:neither you nor heis 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,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.

3、 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:weas well as john like it
he came here to learn englishas well as to know more about life
注意:

4、 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 amrich, i will buy a car.
if he hastime, he will come here.

5、 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
