行为动词一般现在时的变化

一般现在时的基本概念：当表示一个动作经常发生或习惯性发生时，或表示常见的一个状态和一个普遍的真理时，通常用一般现在时，它经常与表示频度的时间状语连用，如，当句子中有always usually often sometimes never every day every year ,on Sunday, in the morning , , , , at one o’clock,等词时，常用一般现在时。 He gets up at 6 o’clock. She usually watches TV in the evening. Sometimes he goes to school by car. Tom often flies a kite on Sunday.

只有第三人称单数动词才要变，其他人称（I, you ,we ,they）则用动

词的原形。

2.行为动词的基本变化格式（第三人称单数）：这里所说的行为动词,指的是除be动词、情态动词和助动词之外的全部动词。行为动词为数众多,主语为第三人称单数he, she, it时,词形有变化。当主语是第三人称单数时，行为动词的一般现在时通常有三种变化：

1、多数在动词后加s play—plays like—likes ,read-reads

sing-sings dance-dances cook- cooks look- looks 2、 以s，x，sh，ch，o结尾的动词加es go—goes wash--washes, watch-watches catch-catches do- does

3、 以辅音字母加y结尾，把y改i再加es fly—flies

study—studies try-tries

(这种变化与名词的单数变复数有点相像)

4. have -has
