xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx原谅LZ把原文删了,我已经不纠结了,心里也有答案了。本来想把整个帖子删了的,不过想想如果能给和我有过同样疑惑的人一点启示也算好。然后真诚的谢谢在这个问题上试图帮助我理清思路的人,嘿嘿,祝你们性福。最后,我应该不会再回复了,让帖子沉了吧:)
