| People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 1 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 2 ; they try to find a solution by trial and error. However, when all of these methods 3 , the person with a problem has to start analysing. There are six 4 in analysing a problem. 5 , the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot ride it to class as he usually does. Sam must 6 that there is a problem with his bicycle. Next the person must 7 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 8 the parts that are wrong. Now the person must look for 9 that will make the problem clearer and lead to 10 solutions. For example, suppose Sam 11 that his bike does not work because there is something wrong with the brakes. 12 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully. After 13 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 14 , his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones. In the end, one 15 seems to be the solution to the problem. Sometimes the 16 idea comes quite 17 because the thinker suddenly sees something in a 18 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 19 the brake. Finally the solution is 20 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem. | ||||
