Have done是現(xiàn)在完成時,I have done my homework.
Had done是過去完成時,I had done my homework before 6 o’clock貌似沒有have did,had did吧我沒見過非謂語動詞是什么舉例說明一下用現(xiàn)在完成時還是過去完成時主要找時間標志就是不做謂語的動詞啊，像分詞和動名詞還有不定式to do,doing,done等His job is to clean the house中就是to clean非謂語動詞做表語了什么是表語be動詞后面的是表語句式結構有主語加謂語加賓語，如I hate you. 還有是主語加系動詞加表語，如I am young.I saw him beaten by his father為什么不能把beaten改為 be beated或 had be beated或 have be beated 為什么要用過去分詞，而不用過去式Be beated=beatenHad be beated語法錯誤，have后面該是beenhave been beat才對嗎不對，前后時態(tài)要一致，沒必要用完成時。上面的beated不對，沒這個詞啊，過去分詞就是beatenHe is consistent in reading books.在介詞in后面，所以用doingI saw him have been beat by his father,語法上還是通的，但是確實沒有必要這么說，有點羅嗦不太明白你為什么喜歡考慮完成時的被動語態(tài)，語意上過去時加上分詞就能表達，別鉆牛角尖了，開學問問老師，我不專業(yè)。。。解釋不明白。。
