面对纷繁的物质世界,作为认识它的高中化学知识,内容是十分丰富的高中化学素有“多、难、乱”之说,“多”指实验现象多,概念多;“难”指知识抽象难懂;“乱”指结构、性质、制法、用途的规律性差,不像数学、物理规律性强。因此,要获得好的复习效果,就必须明确复习要求,重视复习方法,注重记忆的科学性。
In the face of the numerous material world, as a high school chemistry knowledge of its understanding, the content is very rich in high school chemistry known as “more difficult, chaotic ”, “more ” refers to the experimental phenomena and more concepts; “Difficult” refers to the abstract knowledge difficult to understand; “chaos” refers to the structure, nature, system of law, the use of the law is poor, unlike mathematics, physical laws and strong. Therefore, in order to obtain a good reviewing result, it is necessary to review the requirements clearly, attach importance to the reviewing method and pay attention to the scientificity of memory.
