ed A,B), C)and D). You should decide on the best choice and mark the correspo nding letter on the Answer Sheet with a single line through the centre. Pa Questions 21 to 25 are based on the following passage People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the o pinions or ideas of other people. Other times they begin to act without thinking they try to find a solution by trial and error However, when all these method fail, the person with a problem has to start analyzing. There are six stages i n analyzing a problem. First the person must recognize that there is a problem. For example, sa that there is a problem with his bicycle Next the thinker must define the problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if th e problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, h e can look in his bicycle repair book and read about gears. He can talk to his f riends at the bike shop He can look at his gears carefull, After studying the problem, the person should have several suggestions for a pos sible solution. Take Sam as an illustration. His suggestions might be: put oil o n the gear wheels: buy new gear wheels and replace the old ones tighten or loos en the gear wheels Eventually one suggestion seems to be the solution to the problem. Somet imes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum([lHW)between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear whee ls and finds that afterw ards his bicycle works perfectly. In short, he has solved the problem. 21.

Passage 1 Questions 21 to 25 are based on the following passage: People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the o pinions or ideas of other people. Other times they begin to act without thinking ; they try to find a solution by trial and error. However, when all these method s fail, the person with a problem has to start analyzing. There are six stages i n analyzing a problem. First the person must recognize that there is a problem. For example, Sam’s bic ycle is broken, and he cannot ride it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if th e problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, h e can look in his bicycle repair book and read about gears. He can talk to his f riends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a pos sible solution. Take Sam as an illustration. His suggestions might be: put oil o n the gear wheels; buy new gear wheels and replace the old ones; tighten or loos en the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum(口香糖)between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterw ards his bicycle works perfectly. In short, he has solved the problem. 21.In analyzing a problem we should do all the following except ____ . A) recognize and define the problem
