论文部分内容阅读
读者一看题目,可能引起猜疑;此题不就是高中代数第一册第一章第一节的第一例吗?这还值得做起大块文章来么?遗憾的是,有人认为例1简单,授课时往往一带而过,复习时更觉得不值一提。盲目地去搜罗课外的“新题”,到头来,却落得一个抛宗背义,把一个完整的教材体系弄得支离破碎。笔者辗转题海多年,迷途知返,追本寻源回到教材上,在如此例1上花功夫,感到受益非浅。
The reader’s first look at the topic may give rise to suspicion; is this question not the first example of the first section of the first chapter of the first edition of the Algebra Algebra? Is it worthwhile to start a large article? Unfortunately, some people think that Example 1 is simple. When teaching, it often goes over and over, and it is not worth mentioning when reviewing. Blindly searching for “new questions” outside the class, in the end, it ended up being a treachery and a complete textbook system was fragmented. The author has changed the subject for many years, lost his way, and pursued the source to return to the textbook. In this example 1, he took time and felt that he had benefited greatly.
