never having done还是having never done

never having done还是having never done not having done 还是having not done? 现在分词的否定式现在分词作状语时never的位置?nver haveing done 还是having never done? 放在句子开头是Not having done还是Having not done not having done 还是having not done 为什么 我纠结半天了 是having done“绝”不作定语,还是having done“决”不作定语 非谓语动词的否定式是having not been done 还是not having been done?放在句首时 非谓语中having done being done表主动还是被动? 非谓语动词什么时候用having done,什么时候用being done,什么时候用done例如：Finally the 11-year-old girl left her home,( ) never to come back having done的用法 doing having done being done having been done 造句! 高中英语非谓语having been done和done有什么区别吗?成分不同么?还是说有逗号只能用having been done? 翻译:You'll never praise him too much for Ms having done so many good deeds for others. could never have done 非谓语做定语时,having done,和doing有什么区别?如果是在过去式中用having done还是doing？ 原谅某人做过某事用英语怎么说 是forgive sb. having done sth 还是 forgive sb. for having done sth having done和having been done怎么用 如题 not having done 和 having not done 的区别
