1、八年级英语语法专项II八年级英语语法专项II 动词一. 动词是表示动作或处于某种状态的词，它分为行为动词，系动词、助动词和情态动词，动词种类多，变化又复杂，是学习英语的难点之一，下面根据动词的特点进行归类，并提供一些辨别方法，以便于理解和掌握。 1. 行为动词在动词中数量最多，它含有实在的意义（又叫实义动词），表示动作或状态，在句中可以单独作谓语，行为动词又分为及物动词和不及物动词，及物动词后面必须加宾语，意义才完整，不及物动词后面不能直接带宾语，常需要在宾语前加介词才能带宾语。 eg: We study English very hard. She has a book in her han

2、d. The sun rises in the east. 2. 连系动词本身有一定词义，但不能独立作谓语，必须与表语一起构成谓语，常见的连系动词有：be, look, sound, get, become等。 eg: My parents are both farmers. The milk tastes terrible. The song sounds good. 3. 助动词本身无词义，不能独立作谓语，必须和主要动词构成谓语，表示疑问，否定，时态或其它语法形式。常见的助动词有：be, have, do, will, shall等。 eg: Do you have a brother?

3、Have you got an English-Chinese dictionary? I didnt go to the cinema yesterday. 4. 情态动词本身有词义，但不能独立作谓语，只能和主要动词一起构成谓语，表示说话者的语气和情态，情态动词没有人称和数的变化，情态动词本身可以构成疑问和否定，常见的情态动词有：can, may, must, will, shall, need等。 eg: Can you sing the English song? Everyone must get to school on time. 二. 动词的时态：（一）时态概述：作谓语的动词用来

4、表示动作（情况）发生时间的各种形式称为时态，英语中的时态，就是通过特殊的动词词尾或加一些相关的助动词be, have（has）等，用来表示动作或事件发生的不同时间和方面。 eg: He reads newspapers every day. He read the newspaper yesterday. He is going to read the newspaper tomorrow. （二）一般现在时： 1. 动词变化：一般现在时主要用动词原形表示，但第三人称单数后要加词尾-s，另外be和have有特殊的人称形式。 在加词尾-s时要注意：情况加法例词一般情况加-sreads, writ

Are you good at English? 4. 一般现在时的否定式是do not（dont）或does not （doesnt）动词原形来构成的，be动词做谓语动词只需在be后加not构成否定。 eg: I dont like oranges at a
