怎么区分谓语动词,to do doing done 和to be doing to be done to have do

to do 是不定式。做状语一般表示目的。如 to wake up early in the morning,he set the clarm 。to do 也可以做结果状语,表示意料之外的结果。也可以做原因状语。比如 nice to meet you 。有的动词后面又必须接to do。那就多了去了。可以网上搜索。doing 是现在分词,也是动名词形式done 是过去分词to be doing 是to do 的进行式 如 he seems to be waiting for her girlfriendto be done 是to do 的被动形式 如 he seems to be killed last night 。to have done 是 to do 的完成形式 1。he seems to have known the fact already。2。i'm so happy to have kept you by my side for so long。being done 是doing的被动形式 如 :being killed last month,the body is smelly now。having done是 表示主动 完成 如 :having known the truth,she can hardly forgive him。having been done 是表示 完成 被动 如：having been told many times,he finally understand it。
