导入就是在一节课教学开始时，教师为有效地导入新课而进行的一种创造性劳动。它既是课堂教学内容的一部分，又是组织教学的科学而巧妙的手段。它如同桥梁，联系着旧课和新课；如同序幕，预示着后面的高潮和结局；如同路标，引导着学生的思维方向。总之，导入的过程乃是整个课 Import is a type of creative work that teachers perform to effectively introduce new lessons at the beginning of a lesson. It is not only a part of the classroom teaching content, but also a scientific and ingenious means of organizing teaching. It is like a bridge, linking old lessons and new lessons; like a prelude, it indicates the climaxes and endings behind; as a signpost, it guides students’ thinking direction. In short, the import process is the entire lesson
