阅读理解 Many young people want to become pop-stars．It is their great ambition(雄心)in life．They think：pop-stars earn a lot of money, they lead interesting and exciting lives．Thousands of fans adore(崇拜)them, they become famous． Yes, but first they must become stars．Most performances start life with a group．This is the pattern(模式)at the present time．But there are many groups and competition is stiff(激烈的)．Groups appear and disappear almost overnight．Only a small number survive(生存)．Almost without exception(例外)they have to work very hard before they reach the top． And very few reach the top and stay there．In England there are perhaps thirty or so groups at the top．Most of these do not earn so much money, Perhaps 400 pounds each time they perform．What is more, they have quite a lot of examples．They have to pay a manager, for example, he is a key person in their lives and he takes about twenty percent of their earnings－perhaps more．Then there are their clothes, their instruments(乐器)and their van(大篷车)． And don't forget they have to travel a great deal－sometimes 2,000 miles in one week．At times they even sleep in their van instead of hotel just to save money． |
