单选题Do you often feel the quality of the goods we buy these days isn"t as good as it ought to be? In the past, when things were made by hand, it seems there was a lot of pride in individual workmanship. People were really proud of things they made. But now, of course, individuals don"t make things. Most things are made on assembly lines and one person only has a very small part in putting something together so there isn"t any workmanship any more. A good example of this is a friend of mine, Mary. She bought a toaster last summer at a sale. She used it, I guess, pretty often, but she only had it a couple of months when suddenly the plastic base of the toaster cracked wide open, and at the same time the heating system in the toaster burned out. She took it back to the store, but the clerk in the store said they wouldn"t take it back, and they wouldn"t give her money back, because she bought it on sale. So the only thing she could do was to buy a new one. I"m sure Mary is more careful when she buys things now, and that"s what we all have to be.

单选题Did you examine your paper money closely? See if you can locate a ＄5, ＄10, or ＄20 bill printed before 1964 and marked "Federal Reserve Note" over the portrait. In the upperleft portion above the seal, a statement written in fine print says that the note is legal tender (法定货币) and that "it is redeemable (可兑现的) in lawful money at the United States Treasury (美国财政部), or at any Federal Reserve Bank (联邦储备银行)." Does this mean that the bin is not lawful? At the bottom center the same bill says, "Will pay to the bearer on demand X dollars." Does this mean that your X-dollar bill is not X dollars? Much confusion exists about the real nature of money. Many people think that money has no value unless it is backed by gold or silver. They think that the Federal Reserve note is only a symbol for money, and that real money is the metal backing the note. Some people look on money as wealth and believe that it must have intrinsic (内在的) value. If we were to study the history of money, we would find that in different places and at different times a variety of things have been used as money. Cattle, shell, beads (珠子),tobacco leaves, and various metals--including iron, zinc (锌), bronze (青铜), and copper--have all been used as a basis of exchange. The precious metals, particularly silver and gold, have proved most satisfactory for this purpose and have been most commonly used in modem times. Until early 1968, the United States backed its Federal Reserve notes with 25 percent gold, but this did not mean that citizens could use gold as money or convert paper dollars to gold. Clearly, it is not what money is but what it does that is important.
