经常会听到考生出了考场以后的一些感受:某道数学题不难,考得很基础,而且平时这些类题做得多了,自以为胜券在握,谁知却在这个地方丢了分.这就是典型的“会而不对”现象.笔者归纳了解题中容易犯的一些“低级”错误,希望能引起同学们的重视. I often hear some of the candidates’ feelings after going out of the examination room: A math problem is not difficult, and the test is very basic, and these types of questions are usually done more than ever. They think they are winning the game. Who knows but lost points in this place. This is a typical “can not ” phenomenon. The author summarizes some of the “low ” mistakes easy to make in the title, hoping to arouse the attention of the students.
