   Among the lesson I had in my schooldays, the one given by an American is the most unforgettably. One morning, our teacher told us he had been invited an American to give us a lesson. Then a man came in. He introduced himself with English and began his class. It was different from those classes they had before. He told many funny jokes, teaching us English songs and helped us act out dialogues. He neither taught us English grammar or asked us to do written exercises.
