第10题: [简答题]1. 书本知识和实践经验哪一类更重要 2．我的理由。 参考答案: Not Everything That Is Learned Is Contained in Books Would you want a doctor to operate on you who has only learned about operations from a textbook Would you want a dentist to drill your tooth who has never before done so The answer to these questions is obviously“no"．Knowledge gained from books must always be complemented by knowledge gained from actual experience，to be of real value．Of the two，the latter is certainly more important．The reasons are as follows： The first and most important reason is that knowledge from books is theoretical knowledge， while that gained from experience is applied knowledge．In any field of endeavor，actual experience is a must to fully understand how to do something，whether it be driving，teaching or cooking. The second reason why knowledge gained from experience is more important than book knowledge is that all new inventions and all creative endeavors do not come from books，but from experiments and experience．In other words，the knowledge contained in books is old knowledge． In conclusion，while knowledge gained from books is important，and can lay a basic foundation for learning，it is our actual experience which enables us to really learn how to do something，how to face and resolve the inevitable issues that come up which were not covered in the books．
