由于中学生正处在青春期,声带处于变声阶段,特别是男生的声音变化较大,因此,以集体唱歌为主要形式的音乐课难以进行。而采用现代化的视听设备开展中学生音乐欣赏课,更容易让中学生接受。 As middle school students are in adolescence, the vocal cords are in the stage of changing vocals, especially the voice of boys is changing greatly. Therefore, it is very difficult to make music lessons with collective singing as the main form. The use of modern audio-visual equipment to carry out secondary school music appreciation class, more easily accepted by middle school students.
