经常对做过的错题进行分析是一个好习惯.于婧婧同学就是如此,让我们去看看吧.期末临近,我们总会进行多次的模拟练习,而每次的题目都不一样,或易或难,总能反映一些问题.比如说,在第一次模拟练习中,我在最后一题失了分,其原因不是其他的,而是模型识别错误,应该选用不等式组来解答,我却用了二元一次方程组,很显然,方向选择出错,被扣了好几分.在第二次模拟练习中,我被扣的分更多 Often done on the wrong question is a good habit to analyze. Jing Jing students is the case, let us go and see it. At the end of the approaching, we will always conduct many simulated exercises, and each time the subject is not the same, Or easy or difficult, always reflect some problems.For example, in the first simulation exercise, I lost points in the last question, the reason is not the other, but the model recognition error, you should use the inequality group to answer, I used a binary system of equations, it is clear that the wrong choice of direction, was detained a few points in the second simulation exercise, I detained points more
