1、定义:表示现在或现阶段正在进行或发生的动作。句中常有now,look,listen等词。
如:I am washing clothes now.
Look! Liu Tao is climbing the tree.
Listen! Jane is singing in the music room.
2、构成:be动词(am/is/are)+ 动词现在分词(V-ing)
3、动词现在分词构成:
一般是在动词原形后加ing。

以不发音的e结尾的动词,去掉e,再加ing 。
如:write-writing,make-making,ride-riding,take-taking

如:sit-sitting,swim-swimming,put-putting,run-running,stop-stopping,get-getting,begin-beginning,jog-jogging,forget-forgetting
4、动名词其实就是动词的现在分词,它既有名词性质(可作主语),又有动词性质(可带宾语)。
如:Asking the way
