何为中档题?考试说明中的定义为:难度为0.4~0.7之间的题为中档题.一般中档题占整个试卷的50%,中档题加上基础题占到试卷分值的80%以上,抓好这80%就能在高考中取得好的成绩.由此可见做好中档题是取得数学高分的必要条件,也是首要条件.下面我们从审题、解题思路和方法、回顾和反思等几方面来谈谈如何提高解中档题的正确率.

What is the mid-range title? The test description is defined as: difficulty for the title of the mid-range between 0.4 ~ 0.7 title mid-grade questions accounted for 50% of the entire papers, mid-range questions plus basic questions account for more than 80% of the papers score , Do a good job this 80% can get good grades in the college entrance examination.Thus we can see the mid-range question is to obtain the necessary conditions for math high score, but also the first condition.From the exam, problem solving ideas and methods, review and reflection And other aspects to talk about how to improve the correct rate of solution mid-range questions.
