长期以来 ,阅读教学存在着两种常见的弊端 :一是缺乏动态机制。对教材内容原型输出 ,只局限于平面传授 ,没有揭示出其中的动态因素和发散性联系 ;二是缺乏实践意识。只注重结论 ,缺乏结论传授过程中的能力训练和结论之后的延伸巩固。若要长善救失 ,必须突出教学中的读写互动因 For a long time, reading teaching has two common disadvantages: First, there is a lack of dynamic mechanisms. The prototype output of the teaching material is limited to plane teaching. It does not reveal the dynamic factors and divergence links; the second is the lack of practical awareness. Only focusing on conclusions, lack of ability training in conclusions and extension and consolidation after conclusions. To be good at saving, it is necessary to highlight the reading and writing interaction in teaching.
