過(guò)去分詞和現(xiàn)在分詞完成被動(dòng)形式有什么區(qū)別
在紙上默寫你背過(guò)的單詞時(shí)你應(yīng)該合上字典.這句我寫了幾個(gè)句子不知道哪個(gè)對(duì) 1.writing your memorized words on the paper from your memory,you would shut up your dicationary.2.writing your words having been memorized on the paper from your memory,you would shut up your dicationary.用when來(lái)寫 3.when you write your memorized words on the paper from your memory,you would shut up your dicationary.4.when you write your words having been memorized on the paper from your memory,you would shut up your dicationary.分詞和when哪個(gè)比較好?現(xiàn)在分詞的被動(dòng)having been done 與 過(guò)去分詞有什么區(qū)別 哪個(gè)正確?另外,不知道“合上字典”的“合”字應(yīng)該用 shut 還是 close.you would shut up your dicationary.you would close your dicationary.幫我看看吧 這句有錯(cuò)誤的地方嗎?
