连词 可以 连接主、谓、宾、表、副、介、补语、定语、状语、同位语（如下面连词and中的示例）。
and
- I and he went to shanghai. 主语
- I like basketball and football. 宾语
- He is kind and friendly. 表语
- He runs fast and beautifully. 副词
- I went to BeiJing and (to) shanghai. 介词短语
- He came and left. 谓语
- He made me excited and happy. 补语
- My teachers, Mr.G and Mr.D, will come later. 同位语
- My old and beautiful friend. 定语
neither … nor …
含义：既不…也不，两者都不… 。 作主语时，由以下两个特性：
- 由于表否定，即使出现多个主语，动词也用单数。
- 多个主语时，动词形式采用就近原则，如下面第一个句子中want离he近，所以用第三人称单数。
- neither I nor he wants to see you. 主
- I like neither him nor his friend. 宾
- He is neither a teacher nor a doctor. 表
- He was born neither in Beijing nor (in) shanghai.
介词相同，可以提到前面来减少重复
- He found the wallet neither in the car nor at home.
两个介词不一样，不能提到前面
- He died neither upstairs nor downstairs. 副
- He neither called nor came. 谓
both … and …
含义：两者都… ，表肯定，动词要用复数形式。
- Both he and his wife are teachers. 他和他妻子都是老师。
- Both I and he want to see the doctor. 我和他都想看医生。
- I like both beer and white wine. 啤酒和白酒我都喜爱。
both … and … 与neither nor 正好意思相反。
either … or …
含义：不是…就是（二选一），作主语时动词用单数。
- either you or I am wrong.
动词形式采用就近原则，动词离
I最近所以用am。 - you’d better choose either this one or that one.
- He is either a teacher or a doctor.
- He went to either shanghai or (to) Beijing. 介词短语
- I met him either this month or that month. 状语
not only … but also…
含义：不仅…而且…，更强调后者。
- Not only he but also tom went to Beijing. 主
- He has not only a car but also a house. 宾
- He is not only a teacher but also a doctor. 表
- He went to not only Beijing but also (to) Shanghai. 介词短语
- He didn’t come not only this month but also last month. 状语
- He not only teaches English but also writes novels. 谓
as well as
含义：也是，唯一强调前者的连词。
- Tom as well as he went to Beijing.
- I like playing football. as well as basketball.
- He has a house as well as a car.
- He is a doctor as well as a teacher.
- He went to Beijing. tom went to Beijing as well(也：状语）
就近和就远原则
所有连词中一旦涉及单复数情况，除了as well as有就远原则，其他都是就近原则，动词形式只需要看动词前的名词或代词。
- Not only I but also he wants to watch the movie.
就近原则：want 对应距离更近的he，所以用wants。
- He as well as I wants to watch the movie.
就远原则：want对应距离更远的he，所以用wants。
