过去分词been
He has been busy since last week为什么不直接用busy的过去分词,而是用been

过去分词beenHe has been busy since last week为什么不直接用busy的过去分词,而是用been
英语最重要的是理解.
这句话是说他从上星期开始就很忙了.你知道的
但是到现在还一直很忙 所以要用been
如你所说,直接用busy的过去分词那就是He has busied since last week.
这样的句子一看就很不爽.有since必须要有been
如果变成He has busied last week那意思就完全不一样了
意思是他上星期很忙 但没说现在也很忙
has been是完成进行,has done是现在完成 不一样的

have+been +过去分词，现在完成式的被动语态
English has been taught in China for many years.
had+been+过去分词, 过去完成时的被动语态
Cleopatra's nose had been shortened.
