both 的用法，并各造一句

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.(主语)
I like both.两个我都喜欢.(宾语)
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(the these,her) children；
也可以说both of the(these,her)children；
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(you,them),一般不说both us(you,them),但可以说us(you,them)both.
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.(连接两个主语)
She can both dance and sing.(连接两个谓语动词)
Mary is both kind and beautiful.(连接两个表语)
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.(两个男孩都聪明)时,否定句当为
Neither of the boys are clever.(两个男孩都不聪明).
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~
