要实现知识和能力的相互转化，关键在于实践。严格训练便是一种特殊的实践形式，它是实现知识转化为能力的主要手段和必由之路。
训练必须讲求实效。训练的目的是为了将知识转化为能力，应该根据这一目的来确定训练的内容和方式。如果离开了这一点，任何训练便都失去了意义。因此，必须从教学实际出发，练有实效。练不在"多"而在"精"，要以少胜多。针对问题进行反复多次的训练，帮助学生提高。

Take your time
For thousands of years, animals have trodden a slow path, their spirits together with the body. But our human being's transportation is too fast. The body moves but the soul is left behind. We try to free ourselves in convenience, but we only imprison the soul. Since we invented how to count hours, we do everything to short the time, short the deadline. But the time saved can't be shorten. Nowadays, we spend lots of time staying in front of a TV just changing the channels, while we have no time to talk with a good friend or play with our family. We have plenty of time to search old news on the internet, while we hardly think about our life. In the end, the only thing apparent is our loneliness.
Take your time, please. Try to follow the natural steps and have your own clock. Try to share your time with everybody you love, share your mind, your happiness and sadness. Try to read the world we live in, do not only catch a quick glimpse at the society.Someday, when we know how to spend every second in our life, we can then live our own life.

学生有时反映，"化学不好学，学不懂，记不住，不会用"。这主要是因为他们还没有掌握化学知识结构和内在联系。化学变化的实质是物质构成的变化，教师要注重引导学生运用物质结构的理论和化学反应规律的知识，去指导元素及其化合物知识的学习。教师要弄清重点、难点，进而订出规划，具体落实，使知识连贯成索链，环环相扣，先后有序。这样，在教学中就能抓住关键，突出重点，循序渐进，步步深入，就能从整体出发来深刻地理解局部，将局部的知识纳入有机联系的知识整体中，有的放矢，促进学生主动地进行学习，有效地发展学生智能。
