step ⅰ greeting and revision
t: morning, boys and girls! do you still remember the poem i gave you last time?
ss: yeah!
t: who’d like to recite it to the whole class?
s1: me. listen! 心平何勞持戒，行直何用修禪，恩則孝養(yǎng)父母，義則上下相憐。讓則尊卑和睦，忍則眾惡無喧。若能鉆木取火，淤泥定生紅蓮。
t：very good! thank you. i think knowledge is important. but wisdom is more important. if a person only knows how to invent and creat something, but doesn’t think over whether his inventions can bring people the true happiness; or he only does thing for his or his group’s interest. moreover, sometimes what he made can do harm to society, then he will be the most dangerous person in the world. the poem above is very easy to understand. if you do things as it tells us, you can turn out to be a wise man who will bring the world the happiness.
