动名词和现在分词的区别及用法.

关键是现在分词和动名词做的句子成分不一样.
动名词是名词性成分,主要做句子的主语,表语和宾语.
比如I like swimming. My hobby is swimming. Swimming is my hobby.
这里的swimming就是动名词.
而现在分词,可以做定语,状语,补语,表语.
比如There is a man standing there.这里做后置定语.
Being ill today, I won't come.这里做原因状语.
I see him standing there. 这里做补语.
He is speaking.这里做表语.（注意它和动名词做表语的区别,你记住动名词是个名词性成分就可以了）
PEOPLE WAITING FOR THE BUS. 这句话,如果是独立的句子,那肯定是不对的,因为没有谓语.要改成People are waiting for the bus.
如果不是独立的句子,那就有可能对
People waiting for the bus are all women.
