　　答案：

　　Which One is More Important， Knowledge Gained from Practical Experiences or Knowl-edge Acquired from Books?

　　Knowledge can be acquired from many sources. These include books，teachers and practical experiences，and each has its own advantages.

　　The knowledge we gain from books and formal education enables us to learn about things that we have no opportunity to experience in daily life. We can study all the places in the world and learn from people we will never meet in our lifetime，just by reading about them in books. We can also develop our analytical skills and learn how to view and interpret the world around us in different ways. Furthermore，we can learn from the past by reading books. In this way， we won‘t repeat the mistakes of others and can build on their achieve-ments.

　　Practical experiences，on the other hand，can give us more useful knowledge. It is said that one learns best by doing，and I believe that this is true，whether one is success-ful oI think making mistakes is the best way to learn. Moreover，if one wants to make new advances，it is necessary to act. Innovations do not come about through reading but through experimentation. Finally, one can apply the skills and insights gained through the study of books to practical experiences，making an already meaningful experi-ence more meaningful. However，unless it is applied to real experiences，book knowledge remains theoretical and，in the end，is useless. That is why I believe that knowledge gained from practical experiences is more important than that acquired from books.
