英语中,插入语定语从句和双层定语从句区别的问题.希望有人能解答以下的疑问.英语中定语从句插入语问题：如此句：they pointed out the damage which they supposed had been done by last night's storm这里的插入语they supposed一插入,岂不是多了一个谓语动词?这句话可以怎么改写呢?还有双层定语从句中：He is the only person that we know who speaks so many foreign languages.岂不是可以看做一个插入语定语从句把,如who去掉.那么第一句不是就可以改写成：they pointed out the damage which they supposed that had been done by last night's storm了吗?而这就是双层定语从句啊!可书上说这样是错的.
