　　引语作文：

　　Knowledge is a treasure, but practice is the key to it.练习才有进步。

　　参考范文：

　　There is a famous saying goes like that “Knowledge is a treasure, but practice is the key to it.” This saying shows the relationship between knowledge and practice vividly.

　　As far as we know, if we don’t have corresponding knowledge of some fields, we cannot do well in the fields. There are innumerable examples to illustrate this point. For instance, a singer can sing well only if he or she possesses musical knowledge; a dancer can dance well only if he or she knows how to dance; a worker can get the job well-done only if he or she is familiar with the basic principles of the job, and so on. But in turn, if we do not apply what we have known to practice, knowledge cannot play its role. For example, if we have learned different methods of cooking vegetables, but we do not cook, then the different methods of cooking vegetables do not produce value for us.

　　Therefore, if we do not have knowledge, we have nothing to practice, but if we have knowledge without putting it into practice, knowledge is of no avail. So we should acquire as much knowledge and put it into practice.
