In the teaching process, the students are guided to observe, analyze and summarize the rules through pictures, examples and exercises, which improves the students' learning enthusiasm and initiative. However, in the teaching, it is also found that some students still have some difficulties in the choice of crown words, and in the future teaching, we need to strengthen targeted exercises and guidance. At the same time, the design of teaching activities can be more diversified, and some interesting games or competitions can be added to further improve students' interest and participation in learning.
