As a famous saying goes, “Knowledge is a treasure, but practice is the key to it.” Knowledge gained from textbooks must always be complemented by knowledge gained from practice so that we can truly master it.

Several facts can account for this saying. To begin with, practicing leaves a much deeper and lasting impression than mere knowing something. Only through constant trail and error will we be able to commit knowledge in our memory. Besides, practice offers an opportunity for better understanding and further development of methods and knowledge. For example, an experienced doctor knows better about diseases and more therapies to cure them than a green hand, because he has accumulated them through practice of numerous treatment and operations, and therefore grasped the essence of many diseases.

To conclude, practice is of great importance if we are to master knowledge. As college students, we’d better put the knowledge we acquire into practice.

参考译文：

正如一句名言所说：知识是一种财富，但实践是打开财富的钥匙。从课本中学到的知识必须通过实践所得的知识加以补充，我们才能真正掌握。

一些事实可以说明这句名言的合理性。首先，实践给人的印象比简单地了解要深刻长久得多。只有通过不断地实践、纠错我们才能把知识牢记在心。此外，实践使我们有机会更好地理解知识并进一步延伸理论知识。例如，经验丰富的医生比新手医生要更了解各种疾病，也知道更多的治病疗法，因为他从无数次的治疗和手术中积累经验并抓住疾病的本质。

总而言之，如果我们想掌握知识，实践十分重要。作为大学生，我们最好把所学知识付诸实践。

本题要求评论一句名言：“知识是一种财富，但实践是打开财富的钥匙。”并要求给出一两个例子来证明观点。本质上这篇作文要求就理论知识和实践之间的关系进行阐述：实践对于掌握理论知识很重要。可以先引出引言，并简要解释，之后详细阐述引言的合理性并进行举例论证，最后总结并提出自己的建议：要注重实践。
