并列连词引导两个并列的词、词组或句子。

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)例如：

Make up your mind， and you’ll get the chance. 拿定主意，这次你会有机会的。

= If you make up your mind， you’ll get the chance.

One more effort， and you’ll succeed. 再努力一下，你会成功的。

= If you make one more effort， you’ll succeed.

2) both…and两者都。例如：

She plays (both) the piano and the guitar. 她弹钢琴，也弹吉他。

3)not only…but (also)， as well as不但…而且。例如：

She plays not only the piano， but (also) the guitar. 她不但弹钢琴，也弹吉他。

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。例如

Not only does he like reading stories， but also he can even write some.他不但喜欢读小说，甚至还会写。

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。例如：

Neither you nor he is to blame. 你和他都不该受指责。
