“Some university teachers prefer to record their lectures in advance so that students can familiarize themselves with the material before class. Then teachers can use the class time to help students to practice what they learned while watching or listening.
Do you think this method of watching or listening before class is an effective way for students to learn? Why or why not?”

中心句： One more benefit is on the side of teachers. Teachers will be glad that students develop some elementary [“基础性的”] ideas of the content before the class, and they may therefore teach well. 展开explanation：The delight will motivate teachers, enabling them to dedicate their mind, heart and spirit to teaching, and it is only when the teacher is energetic that the students can learn.
