选择题是中考数学试卷中的必有题型,一般占全卷总分的30%,可见选择题所占比例之大,分量之重.由于选择题只需选择正确的答案,不需写出解题的过程,故在选择准确的前提下,应尽量减小计算量,争取更多的时间思考其他题,因此选用巧妙解法是不容忽视的.现介绍几种快速解答选择题的方法,供大家复习时参考.
The multiple-choice questions are necessary questions in the math test papers for mathematics, which generally account for 30% of the total scores of the whole volume. It can be seen that the proportion of the multiple-choice questions is large and the weight is heavy. Because the multiple-choice questions only need to select the correct answer, there is no need to write. The problem-solving process, therefore, under the premise of accurate selection, should reduce the amount of calculation as much as possible, and strive for more time to think about other issues, so the clever solution can not be ignored. Now we introduce several methods to quickly answer multiple-choice questions. Reference for everyone when reviewing.
