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?

在纸上默写你背过的单词时你应该合上字典. . 分词和when从句一样 最好用 when 加分词 表示比较好 强调了时间 句子也简练 when writing your memorized words on the paper from your memory,you should shut your dicationary 作定语 应用过去分词 不能用 现在分词完成被动式having been done “合上字典”的“合”字用 shut 或close都可以. shut 比close通俗 但无需用shut up
