好久没有更新了，应该是因为自己肚子里的东西太少，所以交不出货来吧！可能也因为自己观察能力有限，所以，什么都看不透彻，自然也就没东西写了。希望到了某一天，这样的情形能改变吧！ I haven't upgraded the blog for such a long time bacause I see nothing before,so of course,nothing can be written down.I think my ability of observing is limited,so nothing can be shown clearly.Well,I can write what?!Ok,I realy hope that one day I can improve myself...should improve...
