both…and…连接相同词类的词或相同的句子成分，意为“既……又……”两者都连接两个词作主语时，谓语动词用复数。

她既会唱歌也会跳舞。She can both sing and dance.

2. Neither my mother nor my father likes it, but I like it a lot. 我父母都不喜欢它，但我非常喜欢它。
①neither…nor…既不……也不……表示“既不……也不……”“两者都不”连接两个并列的成分，当连接两个主语时，遵循就近原则。

②neither用于没有冠词、物主代词或指示代词的单数名词之前，动词用单数，而neither of用于名词带有冠词、物主代词或指示代词的情况，名词是复数，而动词可以是单数或复数。
如：（两个学生）没有学生知道答案。Neither student knows the answer.
＝Neither of the students know(s) the answer.
③neither of、none of的区别
两者均含否定意义，neither只能用来指两者，而none是指三者或三者以上，后接复数名词，动词用单数或复数。
