It has been said, “Not everything that is learned is contained in books.” Compare and contrast knowledge gained from experience with knowledge gained from books. In your opinion, which source is more important? Why?
Knowledge gained from experience and that from books are the two major sources where people’s knowledge come from. When asked about which source is more important, the majority may choose experience. Others, however, like me, would like to vote for books, from which gaining knowledge is more efficient, widely-covered and systematic.
No one can deny the fact that acquiring knowledge from books is far more efficient than that from experience. In the time of information explosion(在信息爆炸的时代是否这样说?), efficiency is of vital importance and everyone wants to get more information in less time. By books, we can understand a principle in a single day which may have taken the experts several years to discover(能否用discover a principle?), we can quickly go through the thousand-year-history in several hours, and we can learn about a foreign country without having been there for a minute.
Furthermore, books has another conspicuous benefit, that is its universality(广泛性用这个词合适吗?). Human’s life is finite, too short to experience everything in this (此处想用一个表示“广大”的形容词，不知用什么合适)world. Often there are things that ordinary people cannot experience in their lives. But by reading books, which cover almost every field in this world, can provide what they want to know. For example, only few people can set foot on the moon, but we can also know the details about the moon by reading relevant books.
In addition, knowledge gained from books is more systematic. The knowledge which comes from experience is concrete, specific but often scrap(这几个形容词不知用得对不对，想表达“具体，有针对性，但比较零碎”), while knowledge acquired from books is more systematic and can give an abstract overview.
While it is true that in learning practical activities such as swimming, experience plays a more important role, I think that gaining knowledge from books weighs more because nowadays, we need to know things more quickly, widely, and systematically.结尾是不是最好再写点什么?可是我已经想不出来了-___-||
修改意见:
总得来说还是不错得。
最后一段，可以写成admittedly,
然后加上一段， to sum up, 你可以看一下模板，找找感觉。
