过去分词和现在分词完成被动形式有什么区别
在纸上默写你背过的单词时你应该合上字典.这句我写了几个句子不知道哪个对 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来写 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.分词和when哪个比较好?现在分词的被动having been done 与 过去分词有什么区别 哪个正确?另外,不知道“合上字典”的“合”字应该用 shut 还是 close.you would shut up your dicationary.you would close your dicationary.帮我看看吧 这句有错误的地方吗?
