StepVIII Teaching Reflection
Through the study of this class, most students have already mastered the basic forms and their functions of infinitive. But during the class ,some students can’t participate in the class actively. Later ,I should pay attention to helping students improve their ability to think positively and cooperate with other students.

Of course, some students who are poor in English still need think harder and practice more to consolidate the grammar. Meanwhile, a teacher should be good at developing students’ potential and stimulate their interest in English.
