2.3.2  Impromptu Humor
In the class, there are many unexpected situations. Teachers should change the plan and use humor according to the specific situation. For example, when a teacher was explaining the phrase on the move, he cited the example: Americans are always on the move. At that moment, the upstairs students were moving their chairs that caused great noise. Therefore, the teacher gave another example: The class upstairs is also on the move. The students all laughed happily.

2.3.3  Humorous Comment on Students’ work
Homework is an important process in language teaching. From the exercise that the students have done, teachers can know how well the students grasp the knowledge. Teachers can use some humorous language to give comments. For example, the teachers can write in the student’s composition like this: Your composition is both good and original. However, the part that is good is not original, and the part that is original is not good. It will not only point out the defect in the exercise, but also encourage the students to work harder.
