经验是最好的老师 英语演讲稿
Experience— the best teacher
We gain knowledge in different ways. We gain it from books or by doing something. The knowledge gained by doing something, is experience. What we learn through experience is more lasting than that acquired through reading. It is accurate, complete and permanent. It is first-hand knowledge.
We can learn through our own experience and partly through other peoples experience. A child does not stop playing with fire till he burns his fingers. He learns from his own experience. So, experience is the best teacher.
