理科,行之有效的方法那便是打好基础。打好基础应立足于教材,对概念、定义要理解透彻;定理要亲手证明;例题要仔细推敲;练习应触类旁通;考试与作业中的错题更要究其根源。事实上,高考许多题目都是课本上例、习题的变形。数学除立足于教材外,老师上课讲的课外例题要格外认真琢磨,因为它是蕴涵了丰富数学思想、方法的交汇题。掌握好数学思想、方法再加上适量的训练,定能学 Science, the effective method is to lay a solid foundation. To lay a good foundation should be based on teaching materials, to understand the concepts and definitions thoroughly; the theorem should be personally proved; examples should be carefully scrutinized; practice should be analogous; the wrong questions in examinations and homework should be investigated. In fact, many subjects of the college entrance examination are examples of textbooks and the deformation of the exercises. In mathematics, apart from teaching materials, the extracurricular examples of classes taught by teachers must be carefully studied, because it is a convergence of mathematical thoughts and methods. Mastering mathematics ideas and methods plus proper training
