[单项选择] From Dr. R. S. Scorer of Britain’’s Imperial College of Science comes the latest theory about the cause of lightning flashes.

The notion that learning should have in it an element of inspired play would seem to the greater part of the academic establishment merely silly, but that is nonetheless the case. Of Ezekiel Cheever, the most famous schoolmaster of the Massachusetts Bay Colony, his onetime student Cotton Mather wrote that he so planned his lessons that his pupils "came to work as though they came to play," and Alfred North Whitehead, almost three hundred years later, noted that a teacher should make his/her students "glad they were there".
Since, we are told, 80 to 90 percent of all instruction in the typical university is by the lecture method, we should give close attention to this form of education. There is, I t
