新教材第118页有这样一道“想想议议”:有两组砖规格相同,A 组一块,B 组两块,每块砖长:宽:高=4:2:1,要使这两组砖对地面的压强相等,可以怎样放?要使 A 组砖对地面的压强比 B 组大,应该怎样放?你能各想出几种放法?教参给出的答案以及其他资料的答案均不相同.我们物理组经过集体讨论认为,该题的 The new textbook page 118 has such a “think about the resolution ”: There are two sets of bricks of the same size, group A, group B, each brick length: width: height = 4:2:1, to make The two groups of bricks have the same pressure on the ground. How can they be put? To make the pressure of group A bricks on the ground larger than that of group B, how should they be put? Can you think of several methods for putting them out? Answers given by teaching parameters and others The answers to the data are not the same. Our physical group believes that the questions are
