分析一下这个英语句法
BBC上的句子：
The government is now launching a voluntary donation scheme, which it hopes will also curb the illegal trafficking in organs.
作为定语从句,which后面为什么还有个it呢?希望能从语法上给点解释!
谢谢!
答
it hopes 是一起的啊,作为句子中的插入语.其实应该是 The government is now launching a voluntary donation scheme,which,it hopes,will also curb the illegal trafficking in organs.
举个例子吧：He also likes the one which I think is the best.这里I think 就是插入语.
能明白么?
