（2）The professor marched into the lecture hall,placed upon his desk a large jar filled with dried beans（豆）,and invited the students to guess how many beans the jar contained.After listening to shouts of wildly wrong guesses the professor smiled a thin,dry smile,announced the correct answer,and went on saying,” You have just learned an important lesson about science.That is Never trust your own senses.”
（3）Twenty years later,the woman could guess what the professor had in mind.He saw himself,perhaps,as inviting his students to start an exciting voyage into an unknown world Invisible（无形的）to the eye,which can be discovered only through scientific methods.But the seventeen-year-old girl could not accept or even hear the invitation.She was just beginning to understand the world.And she believed that her firsthand experience could be the truth .The professor,however,said that it was wrong.he was taking away her only tool for knowing and was providing her with no substitute（替代）.“I remember feeling small and frightened,” the women says,“and I did the only thing I could do.I frightened the course that afternoon,and I haven’t gone near science since.”

教授走进讲堂,他把一个充满了豆干类的大罐子放在了桌子上,并请同学们猜罐子里有多少豆子.当他听完学生们叫出的错得离谱的答案后,教授露出了淡淡的,有点干的微笑.他宣布了正确的答案并说道：你们刚刚学到了有关科学的重要一课,那就是不要凭自己的直觉去判断.
