我在和学生一起测量太阳高度时,学生趴在地上,有的测量,有的绘图,兴致高涨,全然不顾脏与热。这时,教师却犯难了:他们懂得了测量太阳高度的各种方法,知道了正午和早晚的太阳高度,必然会比较起不同时刻的太阳高 When I was measuring the sun’s height with the students, the students squatted on the ground, and some of them measured, and some of the drawings were high-spirited, ignoring the dirt and heat. At this time, the teachers were guilty: They learned various ways of measuring the height of the sun, and they knew the height of the sun at noon and early morning and evening, and they were sure to compare the sun’s height at different times.
