    　　Imagine the situation．You are driving along a desert or on a mountain．You have no idea where you are．You passed the last house two hours ago．Then your car breaks down．It is night and it is cold．You have no mobile phone．What do you do? Well, next time take a GPS with you．This invention may be able to help you．It is a device(装置)which uses satellites(卫星)to find the user's position(位置)．It can find your position to within 20 metres．A GPS cannot start your car, but at least you will know where you are．

    　　GPS, which means Global Positioning System, is a small radio receiver．It looks like a mobile phone．You can hold it in your hand, or put in your pocket．It is sometimes put into a watch or a telephone．We also find GPS devices in cars, planes, or boats．Some of these devices have electronic maps, so you know where you are．For example, in a city they can tell you the name of the street．

    　　There are three parts to the Global Positioning System．The first part is the receiver．You can hold it in your hand, or have it fixed into your car, plane, etc．The second part is a group of satellites orbiting the Earth．The receiver contacts at least four of the satellites and calculates(计算)its position．The third part of the system is a network of ground stations．They are all over the world．They control the satellites and make sure they are working well．

    　　Some people think that in the future the GPS will be as common as the mobile．They are becoming cheaper and more and more accurate(精确的)．There are also new uses for the GPS．Perhaps they will become like watches．Everyone will have one and you will never be lost again．

    　　The United States is truly the land of the credit card(信用卡)．Americans use credit cards to buy almost everything．The use of credit cards has many important advantages(优势)．The use of cash(现金)is limited to the smallest amount．So less money would be stolen．People can carry their credit cards and use them instead of making withdrawals(收回)of cash from their accounts．People can also place orders for purchases(购物)by phone and by giving their credit card number．This is easier and faster than paying by check．

    　　However, the use of credit cards also troubles many Americans．If a credit card owner does not pay all of the money that he owes(欠)at the end of the month, he is really borrowing the money．Until he repays all of it, the rate of interest, often about twenty percent, is very high．Because no payment(付款)is needed until one month after the purchase, many Americans have trouble limiting their purchases．When the bills finally arrive, they see that they do not have enough money．The result is high interest payments．

    1．What is this passage about?

    ______________________________________

    2．What is an advantage of the use of credit card?

    ______________________________________

    3．What makes it easier to pay by credit cards than by check?

    ______________________________________

    5．What's the result if a credit card owner does not pay all of the money that he owns at the end of the month?

    ______________________________________
