物理课一般在初中二年级开设,对于大多数初二的学生来说,这是一个新鲜的、有趣的学科。课上教师和学生可以做很多有趣的实验,如,像魔术师一样让水杯倒立而水不流出;像巫婆一样让鸡蛋自己挤进广口瓶;或者组装一个电路,让报警的电铃响起来, The physics class is generally set up in the second grade of junior high school. For most students in Grade two, this is a fresh and interesting subject. In the class, teachers and students can do a lot of interesting experiments. For example, like a magician, let the cup upside down without water flowing out; like a witch, let the eggs themselves squeeze into the jar; or assemble a circuit and let the alarm bell ring.
