all两者以上都反 none

用法:放在be后,实义动词前。

both:both…… and:同义词 not only...but also

意思都是:既。且。不但。而且。

both 表示“两者都…”,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。

用于连接两个表示并列关系的名词或代词。如:both new york and london h**e traffic problems. 纽约和伦敦都存在交通问题。

he both speaks and writes spanish. 他既会说也会写西班牙语。

说明:作为关联并列连词,它通常应连接两个相同性质的句子成分,但有时后一成分可能省略与前一成分相同的词。另外,若连接两个成分作主语,谓语总是用复数。

如:both she and i are good at english. 她和我都擅长英语。

either...or...意为"或者……或者……;不是……就是……"之意。表示两者之一,连接句子中两个并列的成分。

例如: when the girl is happy, she either sings or dances. 那个女孩高兴时,不是唱就是跳。

(此句中either...or...连接两个动词,因为主语是单数第三人称,谓语动词要用其相应的形式。

)either...or...连接两个主语时,其谓语动词应与最近的一个主语在人称和数上保持一致,这就是我们通常说的"就近原则"。

例如: either you or i am going there tomorrow. 明天要么你去那里,要么我去那里。

若要对either...or...句型进行否定时,只需把either...or...换成neither...nor...即可。

例如: either you or she is good at drawing. 变为否定句应为:

neither you nor she is good at drawing. 你和她都不擅长绘画。
