英语基础-动词的分类

1. 实义动词

实义动词是表示具体动作的词。常见的分类：及物动词和不及物动词。

1. 及物动词：后面直接加宾语，并且必须加宾语；

比如：I love you. I buy a book.

2. 不及物动词：后面不能直接加宾语，必须要加了介词以后才能加宾语；

比如：I agree with you. I live in Beijing.

如何区分及物动词和不及物动词呢？

1. 根据意思；

buy ; eat

2. “动词+ 介词”中的动词为不及物动词；

arrive at ; listen to ; look at

3. 看单词记忆；

V.：既可以作及物动词，也可以作不及物动词

Vt.：及物动词

Vi.：不及物动词

2. 系动词

状态：be动词

表象：seem, appear

保持：keep, stay, remain, stand

感官 : look, sound, taste, smell, feel

变化：get, become, turn, grow, fall

终止：prove

3. 情态动词

情态动词是本身有一定的词义、表示说话人主观态度的词。

情态动词不能单独出现，后面必须和实义动词/系动词（原型）一起构成谓语。

特殊用法：情态动词的完成时表示推测。

1. should have done : 本应该做某事；

2. could have done : 本可以做某事，却没做，表遗憾；

3. needn’t have done : 本无需做某事，却做了；

4. must have done : 一定做过某事；

举例： 明天就要考试了，但小明通宵玩了一晚的游戏。第二天一早匆匆忙忙读了一会儿语文，来到学校考场……

1. 老师刚刚发试卷，他就想睡觉，心里好后悔：我本该早点睡觉的；

I should have gone to bed early.

4. 走出考场，看到同桌兴高采烈，小明想：他肯定努力学习了；

4. 助动词

助动词就是帮助谓语动词一起构成否定、疑问、时态、语态等的词。
