要學好英語，首先要了解句式結構。
英語中有四種基本的句式：陳述句、祈使句、疑問句和感嘆句。
例如：
Declarative: Tom’ll come to the meeting tomorrow.
陳述句：(湯姆明天會參加會議。)
Imperative: Turn to page 232 in your science book.
祈使句：(請把你的科學課本翻到第232頁。)
Interrogative: Where do you live?
疑問句：(你住在哪里啊?)
Exclamatory: That’s awesome!
感嘆句：(太棒了!)
陳述句
陳述句是對事實、安排或觀點進行“聲明”或陳述。陳述句可以是肯定句，也可以是否定句。陳述句以句號(.)結尾。
I’ll meet you at the train station.
(我們在火車站見面吧。)
The sun rises in the East.
(太陽從東方升起。)
He doesn’t get up early.
(他不早起。)
祈使句
祈使句是發出命令(有時是要求)的一種句式。祈使句中一般沒有主語，you是隱含的主語。祈使句以句號(.)或感嘆號(!)結尾。
Open the door.
(把門打開。)
Finish your homework.
(把你的作業做完。)
Pick up that mess.
(把這亂七八糟的收拾一下。)
疑問句
疑問句就是提出問題的句式。疑問句中，助動詞位于主語前面，而主語后則跟著主動詞(例如：Are you coming..?)。疑問句以問號結尾。
How long have you lived in France?
(你在法國住了多久呀?)
When does the bus leave?
(公交什么時候開走的?)
Do you enjoy listening to classical music?
(你喜歡聽古典音樂嗎?)
感嘆句
感嘆句通過感嘆號(!)對一個陳述(陳述句或祈使句中)進行了強調。
Hurry up!
(快點!)
That sounds fantastic!
(聽起來棒極了!)
I can’t believe you said that!
(我真不敢相信你會那么說!)
說完了句式，我們再來看一下基本的句型結構：
最常見的是簡單句，
簡單句
簡單句中沒有連接詞(如and, but, or等)。

(上個星期六，皮特和蘇去了博物館。)
Are you coming to the party?
(你會去那個派對嗎?)
并列復合句
復合句由兩個陳述構成，這兩個陳述由連接詞(如and、but、or等)連在一起。

(我是想來的，但太晚了。)

(公司這年效益不錯，所以給每個人都準備了獎金。)
I went shopping, and my wife went to her classes.
(我去購物，我妻子去上課。)
主從復合句
主從復合句中含有一個獨立的從句，且至少有一個。兩個從句由一個從屬連詞(如which, who, although, despite, if, since等)連接起來。

(我女兒上課遲到了，鈴聲響了一會才到。)

(就是那個男人買下了我們的房子。)
Although it was difficult, the class passed the test with excellent marks.
(雖然難度很高，這個班級還是以高分通過了測試。)
并列復合句—主從復合句
并列復合句和主從復合句都含有一個或以上的獨立的從句。從句由連詞(如but, so, and等)和從屬連詞(如who, because, although等)
