You have no idea_____when we saw so many IT companies booming in our country.
A.that how happy we were
B.how happy we were
选哪一个,为什么?
谢谢!
但书中答案是B,WHY?

A
关系代词THAT在定语从句中常用做介词的宾语，指人或物
the man that he was talking about,,,
the problem that we've spent a lot of time on...
其实the boys that.... 和the building is extablished in New York that......个两个句子差不多的
如果我在the boys后面加个are playing football然后再加that的话，那个两个句子就一样的
Mary has a euphonic voice that..... 这句也是
这里that后面要引出的是a euphonic voice 怎么样
上面个些that还是可以省略的
Most of us don't believe that living thing exist in outer space.
most of us don't believe可以单成个句子，它后面那个that就是引出不相信的内容。

A.that how happy we were

这是一个定语从句， that 后是修饰idea的定语

that起到一个先行词的作用
