现在分词的变化规则

动词的现在分词都是规则变化的,变化规则如下:

1. 以不发音的e结尾的动词,去掉词尾的e加ing,比如:come→coming;

2. 以“ie”结尾的动词,把ie变为y加ing,比如:lie→lying,tie→tying,die→dying;

3. 动词的结尾音节是重读音节,末尾的三个字母是“辅音字母+元音字母+辅音字母”,对应的是“辅音+元音+辅音”的发音,这个时候双写末尾的辅音字母再加ing,比如:stop→stopping, admit→admitting,control→controlling。

4. 剩下的情况是直接在词尾加ing,比如:see→seeing,open→opening,visit→visiting,play→playing,snow→snowing, fix→fixing。

不用进行时的动词

like, love, want, know, understand, remember, depend, prefer, hate, need, mean, believe, forget通常不用于进行时,但是可以用于一般现在时。I’m tired. I want to go home.

与一般现在时的区别

现在进行时强调的是目前阶段暂时性的动作,而一般现在时是长期性的行为。I usually get up at 7 o’clock, but I am getting up at five o’clock this week to cook breakfast for my sick mother.
