1.I went to see you yesterday,but you weren't in.2.My friend booked a hotel room for me after I arrived in Shanghai.3.I booked a hotel in Shanghai three days in advance.4.We simply had a casual meal s...I wouldn't have gone to Shanghai if she hadn't invited me / I hadn't received her invitation 您帮我翻译的这句 这部分 wouldn't have gone时什么时态？？would have done是，虚拟语气 还是 过去将来完成时 结构？ 觉得这里不需要虚拟语气吧。谢谢我理解这是过去发生的事情，那么再讨论这个可能的话就是虚拟语气，主句用would have done, 从句用过去完成时had done。would have done 做虚拟语气的话？ 意思是： 本来应该做，结果 没做， 还是其他什么意思？，对过去的一种预测？ 我也觉得用虚拟语气合适如果不是她来邀请我 / 接到她的邀请， 我是不会去上海的觉得就是一个假设情况。呵呵谢谢是这样没错。事实是我接到邀请了，我去了。那么如果我没接到邀请的话，我没去这件事这就是虚拟了。哦。。多谢您，那 would have done是哪个意思啊，我问您了2个 ，是 应该做，结果没做，还是， 意思是 预测某事？2 I went to see you yesterday, but you weren't in.in 后面 不需要宾语吗？ 这里in难道是副词？哈were not there 也可以吧以后有问题了，多多交流吧。。。would就是虚拟语气的助词，意思是我可能会怎么怎么样，不是预测。you were out和 you were not in是一个意思，都是你不在，你出去了。这是常用法，跟were not there 一样，不过更简洁些。
