Who and from where did the man come to find out if Chinese people are against the state. 怎么样理解由where and who 引导的从句？谢谢！ Where'd you come from? Where'd是什么的缩写？还是写错啦？ select from where like Where are lion from? where is beckham from??? select sum(*) from...where..... Who's John Paul Ⅱ?And where does he live? 有一句歌词是I don't care who you are,where you from是睡的歌 --Who (A.took the pens and books) B(out) C(from) my bag?
