A lesson begins with warming-up, so a more attractive way to present warm-up is a key answer to the question. There are three methods that we can refer to. The first one is to sing a song and students can sing it with teachers together which can enhance friendship between teachers and students. The second one is to guess a riddle which can stimulate students’ interest and help them focus on the lesson. The last one is to play a video related to the topic. When students watch it, they can get a first impression on what we are going to learn today. All these methods can be used in a lesson to achieve this goal.
