The depth of knowledge to be gained from books is much richer and broader than what can be learned from direct experience.
------正文------
       In a sense, I agree with the speaker in that the depth of knowledge gained from books is relatively richer and broader than that from direct experience. However, it should also be mentioned that knowledge learned from direct experience has its advantages too. We will not be able to learn comprehensive knowledge unless the two kinds knowledge are combined together during our studying.

        Admittedly, knowledge gained from books is richer and broader compared with that from direct experience for the reason that such knowledge usually reflects thousands of years' human wisdom as well as some experts' hard working. Before us, numerous learned persons had researched all kinds of problems in various areas, which was recorded in the tremendous volumes of books. It is no doubt that nobody is able to have so affluent direct experience because of the lack of time and energy. Therefore, it is reasonable to make the conclusion that the depth of knowledge gained from books is richer and broader than that from direct experience. Additionally, knowledge gained from books are generally thought for a long time by a lot of people and organized systematically by the writer. Compared with knowledge learned from direct experience, such knowledge digs deeper into the problems, which renders it more irradiative at the same time. For example, it is common for some of us to predict the following day's weather by observing the clouds, but few of them are capable of telling the reasons. In fact, their ability is derived from many years' observation, namely, direct experience. Only through studying books interpreting the scientific reasons behind these phenomena can we really understand and master the relevant knowledge.

         Nevertheless, we should also pay attention to direct experience, which provides with us vivid and direct description of the world. Often, we are still at a loss after carefully reading a book partly because the knowledge contained in the book is too abstract to understand. Under such condition, it is advisable for us to turn to direct experience, which will display a vivid description of such knowledge to make easy our understanding. A case in point is physics experiments helping us to understand the abstruse theories. About four hundred years ago, people were confused with Galileo's theory concerning falling objects. They could not imagine that two objects with different weight would fall at the same speed. However, Galileo proved his theory by doing an experiment in Pisa, which disproved what they had conceived for almost two thousand years.
         
         Last but not the least, much knowledge in books is derived from direct experience and it is direct experience that is able to judge whether knowledge in books is right or not. In my point of view, no knowledge is thoroughly irrelevant with direct experience. It is rare, maybe impossible, that thoughts, concepts and ideas would suddenly appear in one's brain. On the contrary, they are often the result of one's dedication to direct experience. In fact, it was direct experience that made many great inventions possible such as radium, X-ray.
        
         To sum up, while it is reasonable for the speaker to emphasize the importance of knowledge gained from books, advantages of direct experience can not be ignored, which is able to provide with us not only vivid knowledge but also judgment of theories.

good, 思想很深刻，值得学习。

第二段最后一句可能不是很有说服力，前面的例子没有体现出“Only”，只是说明learn from books 的人比没有的更能了解本质。

首先感谢楼上的回复。 加尔闪金的逻辑很严密，only 的理由确实不够充分。  不过我写的的时候蛮紧张的，没顾得上仔细想，而且我感觉写的时候节奏很重要，一旦停一下就很可能写不完。   不知道大家是不是这样。
