The best research often comes from unexpected observations.
最好的研究往往来自意想不到的观察。
I have to remind myself that some birds aren't meant to be caged. Their feathers are just too bright. And when they fly away, the part of you that knows it was a sin to lock them up DOES rejoice. Still, the place you live in is that much more drab and empty that they're gone. I guess I just miss my friend.
重要的不是金钱，而是你爱的人。
释义：一片浮萍顺水漂流，终飘向大海，人生又哪里不能再次重逢呢？
好的教师不是仅仅传授知识，而是激发学生自己去探索和发现
