1、动词讲解与练习一、动词分类1.行为动词（实义动词）。实义动词可分为及物动词（一般情况下，其后要跟宾语，意义才完整）和不及物动词（之后不能也不需要跟宾语），许多动词既是及物动词又是不及物动词。如：We study English.(及物) We study hard.（不及物）2.连系动词。连系动词和表语一起连用，充当谓语。常用的连系动词是be（是），look（显得），feel（感到），turn（变成），get（变得），become（成为）。3.助动词。助动词本身没有词义，不能独立作谓语，只能和主要动词一起构成谓语，表示否定，疑问，简略答语等。如：Do you like oranges ?Yes
2、, I do. I dont know him . Will you go to the zoo?4.情态动词。本身有意义，但不能独立作谓语，只能和主要动词一起构成谓语，表示说话人的语气和情态，情态动词没有人称和数的变化，常见的情态动词有：can（could）, may（might）, must, need等。二、动词时态在英语中，同样一个动作，由于发生的时间不一样，所表示的形式就不一样，这就叫时态。1、一般现在时用法：(1)表示经常发生，反复进行的动作，常用的时间状语有：often，usually，always，everyday，sometimes等。We have breakfast ev

They will stay at home if it rains .构成：(1).主语不是第三人称单数时，动词用原型。如：They often play football .(2).主语是第三人称单数时，动词必须用第三人称单数形式，即在动词原型后面加s。She likes English .第三
