People do not analyze every problem they meet. Sometimes they try to remember a solution, from the last time they had a 1 problem. They often accept the opinions or ideas of other people. Other times they begin to act without 2 , they try to find a solution by trial or error. 3 , when all of these methods 4 , the person with a problem has to start analyzing. There are six 5 in analyzing a problem.
6 the person must recognize that these is a problem. For example, Sam's bicycle is broken, and he cannot ride it to class as he usually does. Sam must 7 that there is a problem with the bicycle.
Next, the person must find 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 decides that his bicycle does not work because there is something wrong with the brakes. 11 , 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 12 the problem, the person should have 13 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 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 new or sees something in a different way. Sam, for example, suddenly sees there is a piece of chewing gum (口香糖) stuck to a brake. He 18 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.
