第二节 读写任务（共1小题，满分25分）

阅读下面的短文，然后按照要求写一篇150词的英语短文。

When students first go to a library, they may be at a loss as to what to read of all the different

subjects. Well, Bacon tells you to “look at weak places in your armor (盔甲)”, and shows you how to fill up the blanks in your knowledge. On the other hand, it is no good just trying to fill your mind with knowledge. Knowledge in itself is often useless. A mind filled with too much knowledge is like a room too full of furniture; a man cannot walk about freely in it, and look out of the windows. It is much better to concentrate on a few subjects that interest you and to deal lightly with the others than to march heavily through the whole range of learning, like a silly tourist going through a museum and not missing a single object. If you try to master every subject you may become very wise, but you will be very lonely and you will probably lose all your friends. So you must learn to pick and choose, and you must also learn to look here and there in a library like a camel eating grass on the grassland. If you watch it eating, you will see that although he is supposed to be one of the most stupid animals in the world, he has at least one of the qualities of the cultured man, the power to pick and choose. A student looking for mental food in a library should take the camel as his model.
