1、初中物理课本第一册第2页第3行:“例如飞机从北京飞往上海,它的地理位置在改变,但飞机仍然是飞机,它并没有变成别的东西。……这些都是物理现象。”这里,教材把物体和物质混为一谈了。“它”是指飞机,“它并没有变成别的东西”只能说明“飞机仍然是飞机”,即物体没有变化,与物质有没有变化不是一回事。如果飞机飞到上海后被拆散(不是飞机了),但只要组成飞机的物质没有变化,仍属物理现象。因此,用此例说明物理现象欠妥。笔者建议:“但飞机仍然是飞机,它没有变成
1. In the junior high school physics textbook booklet 1, page 2, line 3: “For example, if an airplane flies from Beijing to Shanghai, its geographical location is changing, but the plane is still an airplane. It has not become something else.... These are It is a physical phenomenon.“ Here, teaching materials confuse objects and substances. ”It“ refers to the aircraft. ”It does not become something else“ can only indicate that ”the aircraft is still an airplane“. That is, the object has not changed. It is not the same thing as if the material has changed. If the aircraft is disassembled (not an airplane) after it flies to Shanghai, it is still a physical phenomenon as long as the material that makes up the aircraft does not change. Therefore, use this example to explain that the physical phenomenon is not right. The author suggested: ”But the plane is still an airplane and it does not become
