大英教材1,unit2中的"he sounds as if he had a cold or something"是虚拟语气吗?
对过去事实虚拟从句不是要用过去完成时吗?

你好
he sounds as if he had a cold or something是虚拟语气,是对现在事实的虚拟,所以从句用的是一般过去式：had
对过去事实虚拟,从句要用过去完成时（但上面的句子不是噢）比如：He talks about Rome as if he had been there before．他说起罗马来好像他以前去过罗马似的.
保证准确率~

祝你学习进步,更上一层楼!
不明白请及时追问,满意敬请采纳,O(∩_∩)O谢谢~~
再问：第二句中的“if he had been there before”，应该不是过去完成时吧，它只是对“has been there”实行一般过去时态罢了，因为“has been there”表示已经到过那里了。这是我的理解，对吗？
再答：。。。。。。if he had been there before 是过去完成时。过去完成时：had done （这个理解吧）过去式：was was的过去完成时：had been was there 的过去完成时：had been there
再问：你看看那个as if 句型怎么理解
再问：收到吗
再答： as if 好像。。犹如。。。没问题吧。。收到，比较慢而已
再问：我感觉这里应该用虚拟语气，但是又不符合虚拟语气的语法
再答：。。。哪里不符合了。 he sounds as if he had a cold 他听起来好像感冒了是对现在事实的虚拟，所以用从句用过去式。因为你不知道到底他是不是真感冒了。。。所以才虚拟
再问：照片上是sounded
再答： as if 虚拟，从句的时态不受主句时态的影响。关键是看对什么时候事实的虚拟。
再问：那就是说?
再答： - - 关键是看对什么时候的事实虚拟了对现在：He sounded as if he had a cold. 对过去：He sounded as if he had had a cold.

He appeared as if he were sick.后面虚拟语气为什么用were而不是had been 英语虚拟问题He looks as if he had been ill for long.虚拟语气定义是说动作或状态不 as if 虚拟语气的问题,He talks about Rome as if he had been to there Hetode me that he had had a cold for three days.此句中的“had had 虚拟语气He talks as if he knew where she was .He talks as if he 英语翻译It sounds as if it is raining.He talks as if he is drunk as if引导的虚拟句是否遵循时态倒退原则呢?He talks about Rome as if he had been 为什么是He told me that he had had a bad cold for two days. he acted as if nothing had happened. He told as if he knew everything.还是He told as if he had know he had got a bad cold 同义句转化 He had a cold because he caught him.He had cold ___ __
