作业帮虚拟语气 请教rose老师

我是这样做的。根据这三条语法公式 现在事实相反：if+过去式(be的过去式用were)，主语+would(could/should/might)+do 与过去事实相反：if+had+done，主语+would(could/should/might)+have过去分词 与将来事实可能相反：if+动词过去式/should+动词原形/were to+do， 主语+would(could/should/might)+动词原形 第一题根据 如 I t was lucky that the old lady was not in the house when the fire broke out . Otherwise ,she would have lost(lose) her life.主句是I t was lucky that the old lady was not in the house when the fire broke out . 从句是Otherwise ,she would have lost(lose) her life，主句中有was，说明属与过去事实相反这一 条，那么otherwise引导的从句she后应该用had done呀 ,（otherwise 相当于if ） 而答案却是would have lost。再说主句也没有用主语+would(could/should/might)+do ，没有一一对应 如果这个题目象下列 这样很工整的例子，我是能够判断出来的， If my brother were here,everything would be all right. 但是题目中没有if 我就分不出哪个用主句，哪个用从句的模式套？
解题思路： 含蓄虚拟条件句
解题过程：
孩子，你对这道题理解有误。这道题考查的是含蓄虚拟条件句。所谓含蓄虚拟条件句，是指将条件从句隐藏在上下文一定的短语中的一类条件句。本题是有otherwise暗示的条件，又称为前陈后虚式。强调一下：otherwise是副词，不能引导句子。
I t was lucky that the old lady was not in the house when the fire broke out . （这个句子陈述过去的事实，是一个独立的主语从句。）
Otherwise ,she would have lost(lose) her life.（这一部分才是虚拟语气）
otherwise=if she was in the house (指代虚拟的从句部分)
she would have lost(lose) her life （这句是虚拟的主句部分）
明白了吗？孩子，老师再举几个例子：
1. I'm really busy,otherwise(＝if I weren't so busy),I would certainly go with you.
我确实太忙了。不然的话，我一定和你一块去。
2. You didn't follow my advice, otherwise(=if you had followed my advice), you shouldn't have made such mistakes.
你不听我的劝告，否则的话，你本不该犯这样的错误。
若有问题，再与老师继续讨论啊！祝开心！！
最终答案：略
