生命科学是一门实验科学,生物学中很多知识的更新都归功于实验技术的进步,好的实验方案往往能达到事半功倍的效果。纵观高中生物教材,很多经典实验的设计都十分巧妙,既易懂又精确。但是在练习和考试中很多学生往往面对实验设计题目没有解 Life science is an experimental science. The update of many knowledge in biology is attributed to the advancement of experimental technology. Good experimental programs can often achieve a multiplier effect. Throughout the high school biology textbooks, many classic experimental design are very clever, both easy to understand and accurate. However, in the practice and examination, many students often face the problem of experimental design without solution
