Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.

重要的是不要停止提问。好奇心有其存在的理由。

教师的人格是教育的基石。

生活就是抓住机会尝试新事物。
