首先，无疑有问。在教学过程中，常出现这种现象：你问学生说懂了，再问学生又答错了。似乎已真的理解了，实则是似懂非懂，然而又提不出问题来。对此，要具体分析，查清原因，区别对待。有的学生看书学习，一目十行，走马看花，自然提不出问题，有的甚至有疑不问，这些都需要 First of all, no doubt asked. In the teaching process, this phenomenon often occurs: You ask the students to understand, and ask the students to answer the wrong. It seems to have been really understood, but in reality it seems to be incomprehensible, but it never raises questions. In this regard, it is necessary to analyze in detail, find out the reasons, and treat them differently. Some students read books and study one line at a time. If they go to see flowers, they naturally cannot ask questions. Some even ask questions, and these need to be asked.
