In our discussion with people on how education can help them succeed in life, a woman remembered the first meeting of an introductory science course about 20 years ago.
The professor 1 the lecture hall, placed upon his desk a large jar filled with dried beans (豆),and invited the students to 2 how many beans the jar contained. After 3 shouts of wildly wrong guesses, the professor smiled a thin, dry smile, announced the 4 answer, and went on saying, "You have just learned an important lesson about science. That is: Never 5 your own senses."
Twenty years later, the woman could guess what the professor had in mind. He 6 himself, perhaps, as inviting his students to start an exciting 7 into all unknown world invisible (无形的) to the eye, which can be discovered only through scientific 8 . But the seventeen-year-old girl could not accept or even 9 the invitation. She was just 10 to understand the world. And she believed that her firsthand experience could be the 11 . The professor, however said that it was 12 . He was taking away her only 13 for knowing and was providing her with no substitute (替代). "I remember feeling small and 14 ," the woman says, "and I did the only thing I could do. I 15 the course that afternoon, and I haven't gone near science since."
