both的用法总结

both的用法有两种，它可以和名词、代词连用，也可以和动词连用，在句中作主语、宾语及同位语，也可作定语。现将其用法归结如下：

1)both与名词、代词连用

(1)both＋(of) ＋the/ 物主代词/指示代词+名词，如：

①Both of the cats are asleep. 两只猫都睡着了。

②I bought both of these bottles in China two years ago.

两年前我在中国买了这一对瓶子。

③Both of his daughters are doctors. 他的两个女儿都是医生。

(2)both直接修饰名词时，不加of。如：

【注意】不能说both of children，但可以说 both of the children.

②I've got oil on both hands. 我两手都是油。

【注意】不能说both of hands，可说both of my hands。

(3)在人称代词前一定要用both of，不能说 both we或 both us，但可以说

us both, them both等。如：

①Both of us like skating. 我们俩都喜欢滑冰。

= We both like skating.

②I want both of them. 两个我都要。

= I want them both.

2)both与动词连用

当both在句中作主语的同位语时，也可与动词连用，both在句中的位置有以下三种情况：

(1)放在是动词be之后。如：

①The children are both lovely. 这两个孩子都很可爱。

= Both of the children / Both children are lovely.

②They are both from Australia. 他们两个都是澳大利亚人。

= Both of them are from Australia.

【注意】在感叹句或简略答语中，both应置于be之前。如：

④----Are you both from Japan? ----Yes, we both are.

“你们俩都是日本人吗？”“是的，我们是。”

(2)放在行为动词前。如：

①We both like watching TV.我们俩都喜欢看电视。

②The men both looked French.那两个人看起来都像是法国人。

(3)当谓语动词是由几部分组成时，both要放在第一个助动词后面。如：

①We have both studied acting. 我们俩都学过演戏。

②The rooms have both been cleaned. 这两间屋子都已打扫过了。

3)both作代词时，可单独使用，其后不接名词。如：

①The brothers are good at playing basketball. Both will take part

in the game.这弟兄俩人篮球打得好，他们俩都将参加比赛。

②----Which one do you want?

----I'll take both please.

“你要哪一个？”“两个我都要。”

【注意】both与not连用，是部分否定。如：

①Both the doors are not open. 两扇门并不都开着。

○2Both of us are not students.我们并不都是学生。

====================================================== both 表示“两者都… ”是个副词,也可以做代词,例:

副词:We are both students.

代词:Both of us are students.

它的否定形式是neither 词性和both一样,例:

副词:We are neither STUDENT, 注意是单数名词.

代词:Neither of us IS a student 同样注意也是单数
