both的用法总结归纳
以下是小编为大家总结的both的用法,希望能帮助大家更好地掌握both的用法,提高英语水平。
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)

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。在使用时,要注意下列几点:
一、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。
二、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.
They both enjoy reading.
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。

四、含both的句子变为否定时,是将both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)。
五、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。
