连词
一．定义：
连词是一种虚词，它不能独立担任句子成分而只起连接词与词，
短语与短语以及
句与句 的作用。
连词主要可分为两类：并列连词和从属连词。
二．并列连词（并列关系，选择关系，转折关系）
1.
表示并列关系的连词
并列连词：并列连词用来连接平行的词、词组和分句。
1)
and
和
判断改错：
(
错
) They sat down and talk about something.
(
错
) I saw two men sitting behind and whisper there.
(
对
) They sat down and talked about something.
(
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：
（
1
）
、
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
)
Be
careful,
or
you
will
cut
ur
fingers.=If
you
are
not
careful,
you
will
cut
ur
fingers.
One
more
effort,
and
you'll
succeed.
=
If
you
make
one
more
effort,
you'll
succeed.

、
A and B
当表示整体或者指同一人时谓语动词用单数

，
every
，
many
等 词修饰时，谓语也用单数。

a knife and fork
The mother and teacher is very strict with her son.

）
、
and
连接的是两个相同意思的词，表示“渐渐”
，或加强语气
Read it again and again
2)

两者都
(
后面的谓语动词用复数
)

·同样
（谓语动词就前原则）

and

1)
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：

( pay attention to the differences between
“
on
”
and
“
in
”
) (surface and interior)
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
。

意思为
