Part 5. Comments
When my students took this lesson, they showed a big interest in it. They are active and many students could present themselves bravely. But I know I still have some problems in designing and teaching, For example, a few students still can’t blend into the class. I still need to come up with a better design to draw these students’ attention.【来源：21·世纪·教育·网】
