可持续性不是牺牲，而是机遇。
Perhaps one day you muster the courage, to make a clean breast of everything in the heart only ended up to let others see the joke, because they did not understand you to say what, also don't know why do you think things are so important, say, almost cried out. I think the worst thing in the world, than with full of heart and secret, but no one can tell, but no one can understand!
The beauty of science lies in its ability to surprise us.
我为什么要站到这儿，我站到讲台上，是想提醒我自己我们必须时刻用不同的眼光来看待事物。
