1簡單句、并列句、復合句
根據語法形式，即句子的結構，英語的句子可分為簡單句、并列句和復合句。
1簡單句
句型：主語+謂語
只包含一個主謂結構，而句子的各個結構都只由單詞或短語表示。
They are playing baseball in the garden.
他們正在公園里打棒球。
Her brother and sister both are teachers.
她的哥哥和姐姐都是老師。
2并列句
句型：簡單句+并列連詞+簡單句
(常見的并列連詞有and，but，or)
并列句是由兩個或兩個以上的簡單句連接而成。并列句中的各簡單句意義同等重要，相互之間沒有從屬關系，是平行并列的關系。它們之間用連詞連結。
My friend was at home， and we talked for along time.
我的朋友在家，我們談了好長時間。
Her father is a doc** and her mother is a teacher.
她父親是個醫生，她母親是個老師。
I liked the s**y very much but Li Ming wasn't interested in it.
我非常喜歡這個故事，可是李明卻對它不感興趣。
Hurry up，or you'll be late.
快點，否則你就會遲到的。
3 復合句
句型：主句+連詞+從句;或連詞+從句+主句(包含一個主句、一個或一個以上的從句，或只包含一個從句，但有兩個或兩個以上的主句的句子叫復合句。)
基本句型 五： S V O C (主+謂+賓+賓補) 此句型的句子的共同特點是：動詞雖然是及物動詞，但是只跟一個賓語還不能表達完整的意思，必須加上一個補充成分來補足賓語，才能使意思完整。 賓語補足語：位于賓語之后對賓語作出說明的成分。賓語與其補足語有邏輯上的主謂關系，它們一起構成復合賓語。 名詞/代詞賓格 + 名詞The war made him a soldier. 名詞/代詞賓格 + 形容詞New methods make the job easy. 名詞/代詞賓格 + 介詞短語I often find him at work. 名詞/代詞賓格 + 動詞不定式The teacher ask the students to close the windows. 名詞/代詞賓格 + 分詞 I saw a cat running across the road. S │V(及物)│ O(賓語) │ C(賓補) 1. They │appointed │him │manager. 2. They │painted │the door │green. 3. This │set │them │thinking. 4. They │found │the house │deserted. 5. What │makes │him │think so? 6. We │saw │him │out. 7. He │asked │me │to come back soon. 8. I │saw │them │getting on the bus.
S V O (主+謂+賓)
此句型句子的共同特點是：謂語動詞都具有實義，都是主語產生的動作，但不能表達完整的意思，必須跟有一個賓語，即動作的承受者，才能使意思完整。
這類動詞叫做及物動詞。賓語位于及物動詞之后，一般同主語構成一樣，不同的是構成賓語的代詞必須是代詞賓格，如：me，him，them等 S│V及物動詞│O
1. Who │knows │the answer?
2. She │smiled │her thanks.
3. He │has refused │to help them.
4. He │enjoys │reading.
5. They │ate │what was left over.
6. He │said │"Good morning."
7. I │want │to have a cup of tea.
8. He │admits │that he was mistaken
： S V O C (主+謂+賓+賓補) 此句型的句子的共同特點是：動詞雖然是及物動詞，但是只跟一個賓語還不能表達完整的意思，必須加上一個補充成分來補足賓語，才能使意思完整。 賓語補足語：位于賓語之后對賓語作出說明的成分。賓語與其補足語有邏輯上的主謂關系，它們一起構成復合賓語。 名詞/代詞賓格 + 名詞The war made him a soldier. 名詞/代詞賓格 + 形容詞New methods make the job easy. 名詞/代詞賓格 + 介詞短語I often find him at work. 名詞/代詞賓格 + 動詞不定式The teacher ask the students to close the windows. 名詞/代詞賓格 + 分詞 I saw a cat running across the road.

S V o O (主+謂+間賓+直賓)
有些及物動詞可以有兩個賓語，如：give給，pass遞，bring帶，show顯示。這兩個賓語通常人為間接賓語;物為直接賓語。間接賓語一般位于直接賓語之前。一般的順序為：動詞 + 間接賓語 + 直接賓語。如：Give me a cup of tea,please. 強調間接賓語順序為：動詞 + 直接賓語 +介詞+ 間接賓語。
如： Show this house to Mr.Smith. 若直接賓語為人稱代詞：動詞+ 代詞直接賓語 +介詞+ 間接賓語。
如：Bring it to me,please. S│V及物│o多指人)│O(多指物)
1. She │ordered │herself │a new dress.
2. He │brought │you │a dictionary.
3.She │cooked │her husband │a delicious meal.
4. He │denies │her │nothing.
5. I │showed │him │my pictures.
6. I │gave │my car │a wash.
7. I │told │him │that the bus was late.
8. He │showed │me │how to run the machine.
S V P (主+系+表)
此句型的句子有一個共同的特點：句子謂語動詞都不能表達一個完整的意思，必須加上一個表明主語身份或狀態的表語構成復合謂語，才能表達完整的意思。這類動詞叫做連系動詞。系動詞分兩類：be, look, keep, seem等屬一類，表示情況;get, grow, become, turn等屬另一類，表示變化。be 本身沒有什么意義,只起連系主語和表語的作用。其它系動詞仍保持其部分詞義。感官動詞多可用作聯系動詞：look well/面色好,sound nice/聽起來不錯,feel good/感覺好，smell bad/難聞 S │V(是系動詞)│ P His face │turned │red. 1. This │is │an English-Chinese dictionary. 2. The dinner │smells │good. 3. He │fell │in love.4. Everything │looks │different.5.He│is growing │tall and strong. 6. The trouble│is │that they are short of money.7. Our well │has gone │dry. There be 結構： There be 表示存在有。這里的there沒有實際意義，不可與副詞
there那里混淆。此結構后跟名詞，表示(存在)有某事物 試比較：There is a boy there.(那兒有一個男孩。)/前一個there無實意，后一個there為副詞那里。
