教学反思1

This class, I found that students spent a lot of time taking notes. So there were little time to do exercises . but I think it is really necessary for them taking note in case that they should forget the knowledge . In a word, I should not waste much time dealing with words. 教学反思2 This class focused on the basic knowledge . and I found that they did not have a clear mind about this part of knowledge. The knowledge that the students get is not a system, so when meeting with a difficult question, they became confused again. 教学反思3：

Some students could not concentrate their attention on the whole class. Maybe it’s because there were too much unfamiliar words. Much work should be done. A part of students can translate the sentences in class, and their translation was satisfying.
