Both可作形容词、代词或副词用,意思是“两个”、“双方”、“两个都”.在句中可作主语、宾语或同位语.如：
Both are right.两者都对.
I like both.两个我都喜欢.
Both可参与构成名词词组,也可和动词连用,还可与and构成并列连词.
1.Both和both of 后都可接复数名词,构成名词词组.但Both后的名词前可有定冠词、指示代词或物主代词作修饰限定,也可没有；both of后的名词前却一定要有定冠词、指示代词或物主代词作修饰限定.如：
可以说both children；
也可以说both of thechildren；
但一般不说both of children.
Both of后可接人称代词宾格,both后则不可；但人称代词宾格后可接both.
可以说both of us,一般不说both us,但可以说usboth.
2.、Both与动词连用时,大多数放在系动词be之后,其它动词之前.如：
His parents are both workers.他的父母两个都是工人.
They both enjoy reading.他们两个都喜欢阅读.
若句中谓语动词包含情态动词或助动词时,both大多放在第一个情态动词或助动词之后.如：The bridges must both be built this year.两座桥都必须在今年修建.
kate and Mary have both gone to English.凯特和玛丽都去了英国.
3.Both可与and构成并列连词,连接两个性质相同并在句中作相同成分的并行结构.如：
Both he and his brother are good at English.
She can both dance and sing.
Mary is both kind and beautiful.
4.含both的句子变为否定时,是将改为neither.
如：当肯定句为Both of the boys are clever.时,否定句当为
Neither of the boys are clever..
5.含both…and…的句子变为否定句时,将both…and…改为neither…nor..,连接的两个部分若是名词,可以是单数,也可以是复数.如：
I know both the man and the woman.我既认识那男子,也认识那妇女.
I know neither the man nor the woman.我既不认识那男子,也不认识那妇女.
Both bears and birds would have the bat as their friend.熊和小鸟都会当蝙蝠是朋友.
Neither bears nor birds would have the bat as their friend.熊和小鸟都不当蝙蝠是朋友. 望采纳~
关于both用法。
一、both可用于名词或代词之后，比如你的第二句＂You both are respectable.” 二、可与of连用，后接名词或代词，如你的第三句＂Both of us play the ball.＂ 当然这一句也可以说we both。
三、“每一”这概念应用every或each，何况你这句子不通，我们平时说“把每天都过好才是最幸福的”才通顺。
both什么时候加are
是有的，但是both与not连用表示的是部分否定，如Both Jack and Tom are not our classmates.杰克和汤姆并不都是我们的同学。
若表示两者都不，应该用neither，如Neither Jack nor Tom are our classmates.杰克和汤姆都不是我们的同学。

＂both”的用法和位置。
（要完整的）
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+ +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。
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=========================================================Both的用法及注意事项一、形容词both作“两”、“双”解：1.Both instruments are valuable to this process.（定语）这两个仪器对这个过程都是很有价值的。
2.Both student have made a good few experiments on electricity.（定语）这两个学生都做了不少电学实验。
二、代词both作“两人”、“两者”解：1.Bothe have been to Beijing.（主语）他们两人都去过北京。

四、注意“both+否定式谓语+…”构成部分否定：1.Both instruments are not precision ones.并非这两个仪器都是精密仪器。
2.Both of the books are not helpful.这两本书并非都是有益的。
如果要将上述两句改成全部否定，则就应写成：1.Neither instrument is precision one. The worst way to miss someone is to be sitting right beside them knowing you can't have them. 失去某人，最糟糕的莫过于，他近在身旁，却犹如远在天边。

both 与 be 动词的顺序
最经典的嘛就是《阿甘正传》的：Life is like a box of cholocate,you never know what you will go to get.Miracles happen every day. （奇迹每天都在发生） If you are ever in trouble, don't try to be brave, just run, just run away.（你若遇上麻烦，不要逞强，你就跑，远远跑开） 《简爱》：If God had gifted me with some beauty and much wealth, I should have made it as hard for you to leave me, as it is now for me to leave you. I am not talking to you now through the medium of custom, conventionalities, nor even of mortal flesh: it is my spirit that addresses your spirit; just as if both had passed through the grave, and we stood at God's feet, equal — as we are！ ' -------如果上帝赐予我财富和美貌，我会使你难于离开我，就像现在我难于离开你。
上帝没有这么做，而我们的灵魂是平等的，就仿佛我们两人穿过坟墓，站在上帝脚下，彼此平等——本来就如此！”《终结者》I'll be back.《love story》Love means you never have to say you're sorry。
《乱世佳人》：Tomorrow is another day.还是同样的出处：Land is the only thing in the world worth working for, worth fighting for, worth dying for. Because it's the only thing that lasts.（土地是世界上唯一值得你去为之工作， 为之战斗， 为之牺牲的东西，因为它是唯一永恒的东西） Whatever comes, I'll love you, just as I do now. Until I die.（无论发生什么事，我都会像现在一样爱你，直到永远） In spite of you and me and the whole silly world going to pieces around us, I love you.（哪怕是世界末日我都会爱着你）
