I have been busy since yesterday.
我从昨天就很忙
为什么不写成 I have been busied since yesterday.
这里句子的成分你搞错了
这里不是主谓宾，而是主系表
原来是 i am busy
这里是将am变成完成时，就成为了I have been busy
am就是动词，系动词

2楼的错啦~busy是形容词,不可能像动词那样变形,LZ原来的是对的

I have been busy since yesterday. I have been busy since yesterday.现在完成时是have加过去分词,但这里的过去分词在哪里 I have been busy yesterday afternoon为什么要用have been busy而不用ha I have been sick since yesterday.中have been 是什么是时态为什么要用been. I have been very busy. i have been busy getting ready for the camp since last week翻 I have been busy since Monday这个句子中哪个是过去分词? have been busy”与“I'm very busy”的区别 I HAVE BEEN HERE SINCE TIME i have been skating since nine years I have been in CZ since last year.这话对么?been in后可加since吗 I have lived here since then还是I have been here since then对啊?
