正如于漪老师所说:“在课堂教学中,要培养激发学生的兴趣,首先应抓住导入课文的环节,一开课就要把学生牢牢地吸引住。课的开始好比提琴家上弦、歌唱家定调,第一个音定准了,就为演奏和歌唱奠定了基础。上课也是如此,第一锤就应敲在学生的心灵上,像磁石一样把学生牢牢地吸引住。” As Yu Yi teacher said: “In the classroom teaching, to cultivate the interest to stimulate students, we must first seize the introduction of the text of the link, the students must be firmly entrenched at the beginning of the class begins like a violinist, The singer sets the tone and the first tone is set, which sets the stage for playing and singing, and so is the lesson, and the first hammer should be knocked on the student’s heart, holding the student like a magnet. ”
