回来了，今天早晨差不多六点到的学校。硬座，很受罪，上午睡到十二点，头晕脑胀。睡得不好，论文没写完。

     there is so much to learn and no time to mourn over the dark side of life. busy the schedule and make the best of time. no game, no movie in any other language but english, to make breakthrough, and improve efficiency and take part in more activities. make the best use of the internet.
