许多教师在上课时最怕学生吵闹,一来,课堂秩序不好,二来,怕自己在学生面前没有威信。尤其自然课,许多东西对学生来说,都是新鲜事物。学生的年龄特点决定了其强烈的好奇心,而且,在这好奇心驱使下,他们往往会情不自禁地想说想做。 Many teachers are most afraid of students in class when noisy, one to poor order in the classroom, and secondly, afraid they have no prestige in the students. In particular, natural class, many things for students, are new things. The age characteristics of the students determine their intense curiosity, and, driven by curiosity, tend to feel compelled to say what they want to do.
