he has had trouble with cars and their owners里面的has had 是不是因为这里的人称是第三人称才加了has?
问题描述:
he has had trouble with cars and their owners
里面的has had
是不是因为这里的人称是第三人称才加了has?
答
has 表示完成时 已经
had 有,遇到
不是的 是因为表示完成时态 所以用
sb has/have done sth
如果是一般时态的话 直接写has 就不用加had了
答
has是助动词,没有实意,这里只用作引导一个现在完成时
had是实意动词,有的过去分词.
