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
① 一般是在动词原形后加ing
如:read-reading,drink-drinking,eat-eating,look-looking
② 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
③ 以重读闭音节结尾,如末尾只有一个辅音字母,要双写这个字母,再加ing
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
My hobby is collecting stamps.
He is good at skating.
5、现在进行时的句型转换
