现在分词是指：有动词原形+ing形式组成.具有双重性,一面具有动词的特征,可以有自己的宾语和状语；另一面具有形容词和副词的特征,可以充当表语,定语,状语,补足语,可以表示主动或正在进行的动作.

现在分词（Present Participle）(又称-ing形式、现在进行式) ，是分词的一种，分词又分为现在分词和过去分词，它们都是非限定动词，即在句子里面不能单独充当谓语，但能充当其它的一些成分（定语，表语，补语和状语），并且它们具有动词的性质，所以又是类动词的一种。一般式doing 一般被动式being done 完成式havingdone 完成被动式having been done 所有...

You'd better ask Mr. Wang for help when (you are )having problems.
you are 被省略了而已。

when, after, before, if等连词后面如果直接加动词的话，一定是加V-ing(动词的-ing形式）。
比如：I'll tell you before going there. (去那儿之前我告诉你。）
