1.用法

(1)表示说话时正在进行或发生的动作。

常与now, right now, at the moment等时间状语或动词listen, look等连用.

常和these days, this week, at present(现在)等时间状语连用。

其否定句要在be动词之后加not;变一般疑问句要将be动词提到句首。

(2)动词-ing形式的变化规则

规则	例词
一般在动词原形末尾直接加-ing	work→working  read→reading
以不发音字母e结尾的动词,先去掉e,再加-ing	live→living  write→writing
以重读闭音节结尾的动词且末尾只有一个辅音字母,应先双写这个辅音字母,再加-ing	stop→stopping  swim→swimming run→running  sit→sitting
以ie结尾的重读开音节的动词,将ie改为y,再加-ing	die→dying  tie→tying    lie→lying

【巧学妙记】

现在分词记忆歌诀

现在分词很好记,动词后缀-ing.

词尾若有哑音e,去e再加没问题.

一辅重音闭音节,这个字母要双写.

die, tie要注意,改ie为y再加-ing.
