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.
