(79)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 the windows. It is much better to concentrate on a few subjects which interest you and to deal lightly with the others than to march heavily through the whole range(范围) of learning, like a silly tourist going through a museum and not missing a single object. (80) 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(品质) of the cultured(有修养的) man, the power to pick and choose. A student looking for mental food in a library should take the camel as his model.

Many people in the United States worry about not looking young and attractive. For many people, looking good also means being thin. Other people worry about their health. Many doctors say being overweight is not healthy. But are Americans really fat?
Almost 30 million Americans weigh at least 20 percent more than their ideal weight. In fact, the United States is the most overweight country in the world. "The stored fat of adult Americans weighs 2. 3 trillion pounds," says University of Massachusetts anthropologist(人类学家) George Armelagos. He says burning off that stored energy would produce enough power for 900,000 cars to go 12,000 miles.
Losing weight is hard work, but most people want to find a fast and easy way to take off fat. Bookstores sell lots of diet books. These books tell readers how to lose weight. Each year, dozens of new books like these are written. Each one boasts to help people to get rid of fat.

When anyone opens a current account at a bank, he is lending the bank money, repayment of which he may demand at any time, either in cash or by drawing a check in favor of another person. Primarily, the bank-customer relationship is that of debtor and creditor who is which depending on whether the customer's account is in credit or overdrawn. But, in addition to that basically simple concept, the bank and its customer owe a large number of obligations to one another. Many of these obligations can give rise to problems and complications but a bank customer, unlike, say, a buyer of goods, cannot complain that the law is loaded against him.
The bank must obey its customer's instructions, and not those of anyone else. When, for example, a customer first opens an account, he instructs the bank to debit (把……记入借方) his account only in respect of checks drawn by himself. He gives the bank specimens of his signature, and there is a very firm rule that the bank has no right or authority to pay out a customer's money on a check on which its customer's signature has been forged. It makes no difference that the forgery may have been a very skillful one: the bank must recognize its customer's signature. For this reason there is no risk to the customer in the practice, adopted day banks, of printing the customer's name on his checks, ff this facilitates forgery, it is the bank which will lose, not the customer.
