What time is it still up?

In some can not fall asleep in the classroom I will pretend to be a scholar and then show a pair of good and tireless appearance, "carefully listen to the class". At this time the thoughts have long been waved to the clouds. I always thought of the same things, driving down Pumiang Street in a sports car OF my own design, or having three dogs at home, an Alaska sled dog, a husky, a border collie, and a black and white cat, and living a worry-free life. One boring time actually gave them all good names. Or like Meng Xingsoul and the late sleeper in the scene of the battle, I killed him, just as the class. Then I would walk out into the hallway, take a deep breath, look at the blue, green sky, and say: Time is precious.
