　　Of all the knowledge we have, some comes from the books we read, some comes from personal experience in our lives. Different people attach different importance to different sources. The young and the educated, for example, may emphasize the former, the old may, however stress the latter. In my opinion, both book knowledge and personal experience are of equal importance. 　　Knowledge gained from experience may be firsthand, direct, and unforgettable. Books in the library may be outdated, giving you useless information. Everything is changing and so is knowledge. If you go out to make on the-spot investigations instead of depending on books, it is likely that you may be pleasantly surprised. Moreover, knowledge you get from your own experience will be everlasting. Therefore, it is important that students get involved in practical activities to accumulate different kinds of experience. 　　Experience, however, is limited in terms of time and space. It is impossible for anyone to experience everything to get the knowledge he needs. In addition, society is developing so fast that new problems come up with surprising speed. Over depending on experience could, therefore, make a person narrow minded and prejudiced. 　　Books are a summary of the wisdom of our ancestors. The best way to gain know ledge is, of course, to read books, and in the meantime, participate in various kinds of practicaL activities. A combination of the two will sure[y make us full and well informed.
