我们知道,七、八年级期末考试通常是地区(县、区)为单位组织命题,然而相比中考命题来看,由于研制团队、打磨时间等诸多因素的影响,不少考题仍然有打磨优化的空间,本文梳理两道考题的批阅手记、变式改编,最后再就命题研究提出一些初步思考,供研讨.一、两道考题的批阅手记和变式改编考题1:如图1,平面直角坐标系中,点A的坐标为(4,0),以OA为一边,在第四象限作等边△OAB,点C是y轴上一动点,连接AC,以AC为一边,在直线AC的下方作等边
We know that the 7th and 8th grade final exams are usually regional (county, district) organizational propositions. However, compared to the Chinese exam propositions, due to the impact of many factors such as the development team and the grinding time, many exam questions are still polished and optimized. In the space, this paper combs the examination notes and variant adaptations of the two questions, and finally puts forward some initial thoughts on the proposition research for discussion. One or two examination questions for the review notes and variant adaptations Question 1: As shown in Figure 1, the plane rectangular coordinates In the system, the coordinate of the point A is (4, 0), the OA is one side, the fourth side is an equilateral △ OAB, the point C is a moving point on the y-axis, and the AC is connected to the AC side, on the straight line AC Lower edge
