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~本回答被网友采纳
