过去完成时可以have+动词过去分词,也可以have+been如I've lived here since 1987或I've been here since1987吗

这个是现在完成时,不是过去完成时,过去完成时是had做助动词的
Have+done 是现在完成时基本结构
Have+been+doing 是现在完成进行时
I've lived here since 1987.强调的是我是从1987年开始在这里居住的.
I've been here since1987.强调的是我在这里居住的时间.
不过其实两个都可以看成是基本结构,表达上差别其实不大,不过完成进行时表示的一直持续不断的动作,且常带有感情色彩.

过去完成时可以have+动词过去分词,也可以have+been如I've lived here since 1987或I I've been here since 1976.为什麽要用been?如果改用lived可以吗? I have lived here since then还是I have been here since then对啊? 在英语现在完成式中 i have lived here since my childhood.i have been i 我知道been 是be的过去分词可是一般来说现在完成时是 have/has+动词过去分词（I have lived h 有since,for的现在完成时句子中的动词必须是延续性的吗?如I have lived here since then I HAVE BEEN HERE SINCE TIME 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英语翻译He has been to Beijing since 2007.I have lived in here s 现在完成时问题过去完成时不是说有两个表示过去的时间词时就用过去完成时么I have taught here since 填空 Have you a_____ live here?——of course.I've been lived her I have been busy since Monday这个句子中哪个是过去分词?
