The whole secret of the teacher's force lies in the conviction that men are convertible. 教师力量的全部秘密，就在于深信人是可以改变的。

    No one deserves a bigger thank you than you. One day is hardly enough to show our gratitude.没有人比您更值得如此深厚的谢意。仅这一天远不足以表达我们对您的感激之情。

    Thank you for making learning not a dull thing but a great joy. 感谢您使我们把枯燥的学习变成了巨大的乐趣.
