物理实验年年考,年年有变化,年年有创新,2007年高考物理实验题的显著特点主要体现在以下五个方面。一、源于课本又高于课本,推陈出新高考物理实验题从既定的教材实验中脱颖而出,这就要求考生不能死记硬背实验目的和原理等,而是要理解教材中的实验原理,再根据已学过的实验方法灵活解决变化的新问题,贵在灵活、善于应变.如:全国卷一中第22题的第(2)问是教材验证动量守恒实验的改进,天津卷中第22题的第(2)问、北京卷中第21题的第(2)问
Annual examinations of physics experiments have changed year after year, and there are innovations every year. The significant features of the 2007 physics experiments in college entrance examinations are mainly reflected in the following five aspects. First, from textbooks and higher than textbooks, the physics experiment problems of the new college entrance examination come to the fore from the established textbook experiments. This requires candidates not to memorize experimental purposes and principles, but to understand the experimental principles in the textbooks. The experimental methods that have been learned flexibly solve the new problems of change, and you are flexible and adaptable. For example, the (2) question of the 22nd question in the national volume one is the improvement of the momentum conservation experiment in the textbook verification. Question (2), Question (2) of Question 21 in Beijing
