怎么区分英语的名词，动词，形容词等词

首先把常用的词类给你介绍一下：在英语语法中主要把词分为8大类：
1．名词：表示人、物或地方等,如：John,teacher；table,pen；London；beauty．
2．代词：用来代替名词,以避免重复某个名词,如：I,you,it,that,those,them．
3．形容词：用来修饰或限制某个（些）名词,如：good（man）,white（paper）,every（book）,much（water）,（John is）hon－est,（He seems）lazy．被修饰或限制的名词,叫做主体词（head-word）.
4．动词：表示行为或状态,如：speak,read,go,think,is,seem．
5．介词：表示它后面的名词（或代词）跟它前面的动词、另一名词或形容词的关系.这些名词（或代词）称为介词的宾语.
介词宾语和介词构成介词短语.
He went to school．（介词to把名词school和动词went联系起来）
He stood by me．
He asked for it．
The book on the desk is mine．（介词on把名词book和另一名词desk联系起来）
He lives in a house on the mountain．他住在山上的一幢房子里.

He is sure of it．他对此很有把握.（of联系it和sure．）
It is good for you．这对你有好处.
He is angry with Mary．他生玛丽的气.
6．副词：修饰或限制动词、形容词或其他副词,乃至介词、连词及整个句子.
He walked slowly．他走得很慢.
He did it carefully．他干得很仔细.
He is a very kind man．他是一个非常善良的人.

Luckily,he got back his money．幸好他把钱要回来了.
Historically,China is a great nation．从历史上看中国是个伟大的国家.
7．连词：用来连接词、词组（短语）或句子,如：and,but,or,so；或把一个句子和一动词或名词联系起来,如：when,because,as,though,that．
He visited Hong Kong and Singapore．（连词and把Hong Kong和Singapore连接起来）他访问了香港和新加坡.
She is pretty but cruel．她很漂亮却很残忍.
He does exercise in class or at home．他在课堂上或是在家里做练习.（or把in class和at home两个短语连接起来）

He was writing when it was rainning．下雨时他正在写作.（when把动词was raining和he was writing连接起来）
He became a beggar because he had been a gambler．他成了乞丐因为他爱赌博.
He went to school though he was sick．他虽病了,但他仍然上学.
The news that the enemy had surrendered soon reached us．不久传来了敌人投降的消息.
8．感叹词：用来表示说话时的感情,如Oh!,Alas!,My!上面只是对8大词类粗略的解释.另外冠词、数词也可算作两个词类,冠词只有a,an,the3个字,数词可归入形容词中.

跟语文一样罢了,名词指人或的物称呼,动词就表示动作的词,如走啊,跑啊,形容词就是起修饰作用的,如漂亮的,愚蠢的等
