英語(yǔ)句子按照使用目的和交際功能分為陳述句，疑問(wèn)句，祈使句，感嘆句。

一、陳述句

用來(lái)表述一件事或表達(dá)一種看法，有肯定式和否定式，常用降調(diào)。

1.陳述句的肯定式主要由主語(yǔ)和動(dòng)詞或動(dòng)詞短語(yǔ)兩部分構(gòu)成，如：He finished his homework.

2.陳述句的否定式的構(gòu)成是在肯定式的基礎(chǔ)上在其系動(dòng)詞be(am, is, are, was, were)或情態(tài)動(dòng)詞（can, must, may, should…），助動(dòng)詞（do, does, did, have, has, will, would）的后面直接加not構(gòu)成。如：He didn&39;t finish his homework./She isn&39;t a teacher.

二、疑問(wèn)句

用來(lái)提問(wèn)的句子，句末用問(wèn)號(hào)。疑問(wèn)句考查內(nèi)容有一般疑問(wèn)句，特殊疑問(wèn)句，選擇疑問(wèn)句，反意疑問(wèn)句。

1.一般疑問(wèn)句的基本結(jié)構(gòu)為：Be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞+主語(yǔ)+動(dòng)詞+其他？句子要用聲調(diào)。如：Is your father a teacher? Do you enjoy listening to music? Can you speak English?

2.特殊疑問(wèn)句多數(shù)以who, when, where, what, why, which, whose, how這類(lèi)特殊疑問(wèn)詞開(kāi)頭。其基本結(jié)構(gòu)為：特殊疑問(wèn)詞+一般疑問(wèn)句，即特殊疑問(wèn)詞+be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞+主語(yǔ)+動(dòng)詞+其他？如：What is your father? When will the meeting start?

3.選擇疑問(wèn)句是用來(lái)提出兩種或者兩種以上的選擇（用or連接），要求對(duì)方選擇一種情況回答的問(wèn)句。語(yǔ)調(diào)一般是前面的選擇用升調(diào)，最后一種選擇用降調(diào)。選擇疑問(wèn)句分為一般選擇疑問(wèn)句和特殊選擇疑問(wèn)句兩種。

（1）一般選擇疑問(wèn)句的構(gòu)成：一般疑問(wèn)句+or+選擇部分？如：Do you like red or yellow?

（2）特殊選擇疑問(wèn)句的構(gòu)成：特殊疑問(wèn)句，A or B ? 如：Which colour do you like, red or yellow?

4.反意疑問(wèn)句是一種常用于口語(yǔ)的疑問(wèn)句，這種問(wèn)句由兩部分組成，前一部分是陳述句，后一部分是附加的簡(jiǎn)短問(wèn)句，中間用逗號(hào)隔開(kāi)，因此反意疑問(wèn)句又稱(chēng)附加疑問(wèn)句。

反意疑問(wèn)句的特點(diǎn)：如果陳述句是肯定句式，附加句式用否定句式；如果陳述句是否定形式，附加問(wèn)句用肯定句式。如：They didn&39;t clean the classroom yesterday, did they? 如果陳述句中有no, never, nothing, seldom, hardly, few, little等否定意義的詞時(shí)，陳述句就可以看成是否定句，附加句式就用肯定形式。如：He has few friends, does he?

幾種特殊形式的反意疑問(wèn)句：（1）Let&39;s go to school, shall we? （2）Let us go to school, will you? （3）祈使句（肯定形式和否定形式），will you? 如：Open the door, will you?/Don&39;t open the door, will you?

三、祈使句

表示命令，請(qǐng)求，建議或勸告等。祈使句的主語(yǔ)是第二人稱(chēng)you,常常省略，謂語(yǔ)動(dòng)詞用原形。沒(méi)有時(shí)態(tài)變化，不能與情態(tài)動(dòng)詞連用。有肯定式和否定式兩種形式。如：Be quiet. Stand up, please. Don&39;t shout.

四、感嘆句

用來(lái)表達(dá)說(shuō)話(huà)人強(qiáng)烈的喜怒哀樂(lè)等情緒，用how或what引導(dǎo)。how和what所修飾的詞放在其后，其他部分用陳述語(yǔ)序。在口語(yǔ)中主語(yǔ)和謂語(yǔ)常省略，句末使用感嘆號(hào)。

1.What引導(dǎo)的感嘆句，句式基本結(jié)構(gòu)：

What+a/an+形容詞+可數(shù)名詞單數(shù)+（主語(yǔ)+謂語(yǔ)）！如：What a nice watch (it is)!

What+形容詞+可數(shù)名詞復(fù)數(shù)/不可數(shù)名詞+（主語(yǔ)+謂語(yǔ)）！如:What beautiful flowers(they are)! /What important news (it is)!

2.How引導(dǎo)的感嘆句，句式基本結(jié)構(gòu)：

How+形容詞/副詞+主語(yǔ)+謂語(yǔ)！如：How tall the girl is!/ How hard he works!
