我们每月收到大量来稿,受版面所限,每期只能刊发20余篇,为了扩大杂志的信息量,同时也为了鼓励广大读者的创作热情,我们从2007年1～2合期开始,对部分不能全文刊登的文章,筛选、摘录其中有新意的观点和内容局部展示,希望对读者的教学教研有所启迪,有所帮助.也真诚欢迎大家为此栏目撰写短小精悍的文章(千字以内). We receive a large number of submissions each month, limited by the layout, and can only publish more than 20 articles in each issue. In order to increase the amount of information in the magazines and to encourage readers to create enthusiasm, we started from the 1st to 2nd period of 2007. For some of the articles that cannot be published in full, the ideas and content of the new articles are selected and excerpted. It is hoped that they will be instructive and helpful to the teaching and research of readers. We also sincerely welcome everyone to write short and detailed articles for this column (thousands of words). Within.
