Mr. Brown was a nice teacher．He taught ns science。In the first class，he gave us a talk on an animal called“birdcat”which had died out（灭绝）during the Ice Age．He passed around a skull（头骨）as he was talking．We all took notes carefully and later we had an exam on it．

    When he returned my paper the next day, I found there was a big red“X”on it．I falled! I couldn’t believe my eves! There must be some mistakes! 一 I wrote down exactly what Mr. Brown said．But then I learned that everyone in the class failed．What had happened?

    Very simple! Mr. Brown said that he had made up（编造）all that“birdcat”and there had never been such an animal．So the information in our notes was incorrect．

    But We all felt that was unfair．What kind of exam was this? And what kind of teacher was he?

    “You should have figured it out,”Mr. Brown said．“Actually, the‘birdcat’skull was a cat’s．”Hadn’t he been telling us no other findings about this animal except the skull? He had told us many unbelievable（难以置信）things about the animal，such as the size，the color, the diet…．but none of us had questioned him!

    Mr. Brown said he hoped we would learn something from that lesson．Teachers and textbooks are not always correct．In fact no one is．He told us not to let our minds go to sleep．and to speak up if we ever thought he or file textbook was wrong．

    Mr. Brown's class let me and my classmates learn something important：never fear to look people in the eye and tell them they are wrong．
