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：
①Both children won prizes. 两个孩子都得了奖。
【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。
②I want both of them. 两个我都要。
◆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。
②They are both from Australia. 他们两个都是澳大利亚人。
【注意】在感叹句或简略答语中，both应置于be之前。如：
③How beautiful they both are! 他们俩多漂亮啊!
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。
both 表示两着都… 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

4.He and I are both from Tianjin.(both作同位语。注意both在本句中的词序和上两句不同。)他和我都是天津人。
◆三、“both…and…”起连接词作用，作“两者都”、“又……又”、“不但……而且”解：
注意：“both…and…”能连接各种并列成分，甚至两个句子。
