画龙点睛比喻绘画、作文在紧要之处加上一笔,使其灵活而有神;画蛇添足比喻做事多此一举,反而坏事。“点睛”与“添足”道出了做事要做得恰如其分之真谛,做课件又何尝不是如此?做课件的道理很简单,为了使教学更精彩,即是说当我们用传统方法无能为力或有能乏力时,便请课件出马助 The finishing touches on paintings and writings add a touch to the critical points, making them flexible and godly; “Empty eye” and “adding foot” show the true meaning of doing things properly and doing courseware is not the case? The reason for doing courseware is very simple. To make teaching more exciting, it means that when we use the traditional methods, we cannot do anything or If you can’t work, you will need courseware.
