英语三大基本句型句子按其结构可分为简单句、并列句和主从句。
一、简单句简单句只有一个主语（或并列主语）和一个谓语（或并列谓语）的句子。
We all learn English. (一个主语和一个谓语）My father and mother go to work at 7:00 in the morning.（一个并列主语和一个谓语）He once lived and worked there. (一个主语和一个并列谓语)1.主语+谓语这种句型简称为主谓结构，其谓语一般都是不及物动词，例：Things change.事物是变化的。
Nobody went.没有人去。
--Did you go by sea？你们走的是海路吗？--NO，we flew.不，我们是飞去。
2.主语+连系动词+表语这种句型称为主系表结构，其实连系动词在形式上也是一种谓语动词，但实质上表语成了谓语，例：Mr. Turner is an artist.特纳先生是位画家。
The milk turned sour.牛奶变酸了。
She became a lawyer.她当了律师。
3.主语+谓语+宾语这种句型可称为主谓宾结构，它的谓语一般多是及物动词，例：We never beat children.我们从来不打孩子。
My sister will fix everything.我姐姐会料理一切。
4.主语+谓语+宾语+宾语这种句型可称为主谓宾宾结构，其谓语应是可有双宾语的及物动词，两个宾语一个是间接宾语，一个是直接宾语，例：He gave the book to his sister.他把这本书给了他的妹妹。
I'll write you a long letter.我将写给你一封长信。
5.主语+谓语+宾语+宾补这种句型可简称为主谓宾补结构，其补语是宾语补语，与宾语一起即构成复合宾语，例：I found the book easy.我发现这本书不难。
（形容词easy作补语）I'll let him go.我将让他去。
（不定式go用作补语）注意：有时两个或更多的并列主语拥有一个共同的谓语，甚至并列有两个主语和两个谓语，这样的句子仍然是简单句，例：China and other countries in the east Asia are developing rapidly.中国和东亚其它国家正在迅速地发展。
（China and other countries并列主语）Mr. Wang and I often work together and help each other.王先生和我常在一起工作互相帮助。
6.There be +主语+状语（表示时间或则地点的状语）这种句型是一种常见的特殊句式结构，它表示存在。
There is（not）a twin bed in the room.房间里有（没有）一张双人床。
There are (not) a lot of tourists waiting for their turns.有（没有）许多游客在等着。
There will be rain tomorrow.明天将有雨。
There must be something wrong.一定有什么毛病了。
二、句子成分分析（定语）主语（状语）谓语（定语）宾语（状语）如：(The tall) boy (often) go (to the big) zoo.(The happy) child went (his) home （yesterday）句子成分划分巧计主在前，谓在中，宾语状语后面冲。
短语定语住宾后，形代定语住宾前。
间宾直宾紧相连，直间之间to, for 连。
宾补位于宾语后，地状常在时状前。
