原高中生物课本,是按照在高二讲授一学期,每周2课时的教学时数编写的。现在,教学计划有了改变,高中生物课程虽然仍设置在高二,但是讲授时间由一学期延长为一学年,每周仍授2课时。从去年暑假开始新的教学计划就实施了,因此,要把原高中生物课本加以修改,以适应今后高中生物教学的需要。现在,这项高中生物课本的修改工作,已经完成。下面我们把关于高中生物课本的修改情况,作一简单说明,首先说明修改后的课本全貌,接着再说明哪些内容作了较大的修改。
The original high school biology textbooks were prepared according to the number of teaching hours taught in high school for a semester and 2 hours per week. At present, the teaching plan has changed. Although the high school biology course is still set up in the second year, the teaching time is extended from one semester to one school year, and 2 class hours per week are still taught. Since the beginning of the summer vacation last year, a new teaching plan has been implemented. Therefore, the original high school biology textbook should be revised to meet the needs of high school biology teaching in the future. Now, the revision of this high school biology textbook has been completed. Now we will give a brief explanation of the revision of the high school biology textbook. First of all, we will explain the entire picture of the revised textbook, and then explain what has been greatly modified.
