导入是教师在一项新的教学内容和活动开始前引导学生进入学习的行为方式。英语课堂教学的第一步是把学生引入到特定的英语语言环境之中。在英语教学法中,呈现的作用是提供充分的新的英语感性材料,让学生完成良好的感知任务。学生对语言材料感知、理解的效果如何,很大程度上取决于教师在呈现环节中与学生认知过程协调的效果。 Importing is a way for teachers to guide students into learning before a new teaching content and activity begins. The first step in English classroom instruction is to introduce students to a specific English language environment. In English pedagogy, the role presented is to provide sufficient new English sensory materials for students to accomplish good perceptive tasks. Students ’perception of language materials and their comprehension effect depend largely on the teacher’s coordination with the students’ cognitive process in the presentation process.
