这一章的实验具有十分重要的作用。学生是否能基本上掌握使用低倍显微镜和制作装片的技能,是认识细胞的构造和保证以后的许多实验顺利进行的关键。在笔者所碰到的实验课中,发现不少学生甚至到植物学的学习接近结束时,还不会合乎要求地使用低倍显微镜和制作装片。其原因虽然很多,但主要问题 The experiment in this chapter has a very important role. Whether or not a student can basically master the skills of using a low magnification microscope and making a tablet is the key to recognizing the structure of a cell and ensuring the success of many experiments in the future. In the experiment class that I encountered, I found that many students even went to botanic learning near the end, and would not be able to use the low magnification microscope and make the filming as desired. Although the reasons for many, but the main problem
