it's a waste of time your talking to him

问题描述:

it's a waste of time your talking to him
it's a waste of time your talking to him.
It' doesn't make any difference my being there.
第一句中的your能不能改成you?第二句同理,这两句有没有省略什么的?最好做一下具体分析

第一句不能换.这是现在分词短语作主语.it是一个形式主语,真正主语是your talking to him.
正常语序就是Your talking to him s a waste of time.你跟他说话就是浪费时间.
第二句情况类似.
