某节物理课上,教师叫起一个学生提问:“什么是匀变速直线运动?”学生答:“是速度均匀变化的直线运动。”教师感到这不是期望的答案,但是似乎学生也没错,于是问题就被不置可否地放过去了。其实学生只是把“匀”解释为“均匀”,把“变”解释为“变 In a physics class, the teacher asked a student to ask: “What is a straight line moving at a constant speed?” The student replied: “It is a linear movement with a uniform speed change.” The teacher felt that this was not the expected answer, but it seemed that the student was right. So the question was left untouched. In fact, students only interpret “uniform” as “uniform” and “change” as “change.”
