My dear fellow students,

    The Olympics are just around the corner. Today I want to talk about good manners and courtesy.

    We Chinese have always been respected and highly praised for good manners and courtesy, which have, as well, become precious traditions of our people. In a couple of weeks beyond, a large number of foreign friends will come to China to join us in enjoying the Olympics. Before foreign guests, we should have an easy manner and behave politely and warm-heartedly. In public places, such ugly behaviors as uproar, pushing or squeezing together, spitting and so on should be determinedly forbidden. In a sense, each of us will not simply stand for ourselves but stand for China. Therefore, boys and girls, let’s do it well right now and the eyes of the world are to on us!
