Teachers have always been a sacred and great role in everyone's mind, with high social status and respect. In my opinion, teachers are not only the imparting of knowledge, but also the representative of positive energy. The positive energy of teachers gives people a positive motivation. Teachers are not only standing on the platform to impart knowledge, but also the leaders of students' lives. Teachers are also promoters of students' learning. In the new teacher-student relationship, teachers are the cultivators of students' learning ability. He is no longer simply imparting knowledge, but becoming the motivation and mentor of students' learning, striving to cultivate students' innovative ability and awareness. At the same time, teachers are also the guides of students' lives. In the long life, when students haven't had a preliminary understanding and cognition of this society, teachers need to constantly set up signposts on their life path while imparting knowledge to guide them to higher goals.
