英语.关于THAT的用法..
其实我一定对从句里THAT的用法有点混淆.
有时候,我经常看到THAT前只跟一个先行词,比如说the fact that.
the boys that.
但有时候,我又看见THAT前可以跟一个句子,比如说the building is extablished in New York that.Mary has a euphonic voice that.
什么情况下THAT前面是跟单独的先行词,什么时候是可以跟一个句子?
会有追加分．

答案

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.
