含义
用法
示例
both…
and…
……和
……都
连接两个主语时,谓语动词要用复数形式
Both Li Ping and her father take exercise every morning.
李萍和她的父亲每天都晨练。
not only…
but also…
不但……而且……
连接两个主语时,谓语动词的单复数与最近的主语的数保持一致,即遵循“就近原则”
Not only I but also my mother is going to the museum.不仅我而且我的母亲也要去博物馆。
either…
or…
或者……或者……
Either you or he is right.
要么你对，要么他对。
neither…
nor…
既不……也不……
Neither you nor I am right.
你和我都不对。
注意：
(1)“祈使句＋or＋结果句”与“If you don't…，you'll…”同义，其中or意为“否则”。如：
Hurry up，or you will be late.快点，否则你就会迟到。
＝If you don't hurry up，you will be late.如果你不快点，你就会迟到。
(2)否定句中两部分都有否定词时用and连接。如：
Bill has no brothers and no sisters.比尔没有兄弟姐妹。
(3)“A and B”当表示整体或指同一人时，谓语动词用单数。如：
The mother and teacher is very strict with her son.这个妈妈兼老师对她的儿子非常严格。
【典例剖析】
(2020·湘西)—How time flies! The middle school life is coming to an end.
—Yes.We have to say goodbye，________ our friendship will last forever.
A.and　　　 　B.but　　 　　C.or
剖析：句意：——时间过得真快啊！中学生活即将结束。——是的。我们不得不说再见，但我们的友谊会天长地久。and和；but但是；or否则。空前句意“我们不得不说再见”，空后句意“我们的友谊会天长地久”，句意出现转折，用but表转折。故选B。

注意：
(1)if意为“是否”时，引导宾语从句；意为“如果”时，引导条件状语从句。如：
Could you tell me if they'll come tomorrow？你能告诉我他们明天会来吗？
You can go out to play if your homework is finished.如果你的作业做完了，你就可以出去玩了。
(2)从属连词so…that…和such…that…都表示“如此……以至于……”，但用法不同：so…that…结构中的so为副词，后面跟形容词或副词；such…that…中的such为形容词，后面接名词(名词前可以有形容词或副词修饰)。试比较：
He was such a clever boy that he thought of a very good idea.＝He was so clever a boy that he thought of a very good idea.这个男孩很聪明，他想出了一个非常好的办法。
so…that…结构常与too…to结构互换。如：
My brother is so young that he can't go to school.＝My brother is too young to go to school.我弟弟太小了，不能去上学。
【辨析】when，while，as
(1)若主句表示的是一个短暂性的动作，而从句表示的是一个持续性动作时，when和while都可以用。如：
He fell asleep when/while he was reading.他看书时睡着了。
(2)若主、从句表示两个同时进行的持续性动作，一般只用while。如：
While he played the piano，I cooked the dinner.他在弹钢琴，我在做晚饭。
(3)若主、从句动作同时发生，且强调“一边……一边”的意思，一般要用as。如：
She sang as she went along.她边走边唱。
(4)若从句是一个短暂性动作，而主句是一个持续性动作，可用as/when，但不能用while。如：
When/As he came，I was listening to the radio.当他进来时，我正在听收音机。
(5)若主、从句表示的是两个同时发生的短暂性动作，一般用as。如：
I thought of it just as you opened your mouth.当你一开口我就想到它了。
(6)表示“每当……的时候”(强调规律性)，或主、从句动作不是同时发生，而是有先后顺序时，一般都用when。如：
It's cold when it snows.下雪的时候会冷的。
【典例剖析】
(2020·益阳)You can surf the Internet ________ you want to know more about the 2020 World Middle School Games.
A.if　　 　B.although　 　C.until
剖析：句意：________你想知道更多关于2020年世界中学运动会的信息，你可以上网。if如果，引导条件状语从句；although尽管，引导让步状语从句；until直到……为止，引导时间状语从句。空前句意为“你可以上网”，空后句意为“你想知道更多关于2020年世界中学运动会的信息”，空后是空前动作进行的条件，用if引导条件状语从句。故选A。
