行为动词的一般现在时及相应练习

行为动词一般现在时的变化

我们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—play s like—like s read-read s sing-sing s dance-dance s cook- cook s look- look s

2、以s，x，sh，ch，o结尾的动词加es

go—go es wash—wash es watch-watch es catch-catch es

do- do es

3、以辅音字母加y结尾，把y改i再加es

fly—fl ies study—stud ies try-tr ies

(这种变化与名词的单数变复数有点相像)

那么，什么情况下用行为动词的一般现在时呢？

当这个动作经常发生或表示习惯性的动作时，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every day every year ,on Sunday, in the morning ,often, sometimes, usually, at one o’clock等词时，用一般现在时。

例句：He get s up at 6 o’clock.

She usually watch es TV in the evening.

Sometimes he go es to school by car.

Tom often fl ies 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。
