People do not analyze every problem they meet．Sometimes they try to remember a solution from the last time they had a  36  problem．They often accept the opinions or ideas of other people．Other times they begin to act without   37  ; they try to find a solution by trial and error．However, when all of these methods   38  , the person with a problem has to start analyzing．There are six   39   in analyzing a problem．

       First 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   40  that there is a problem with his bicycle．

       Next the person must  41  the problem．Before Sam can repair his bicycle, he must know why it does not work．For example, he must   42   the parts that are wrong．

       Now the person must look for   43   that will make the problem clearer and lead to  44 ．   solutions．For example, suppose Sam   45   that his bike does not work because there is something wrong with the brakes．At this time, 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  46  the problem, the person should have  47  suggestions for a possible solution．Take Sam as an example   48  , his suggestions might be: tighten or loosen the brakes, buy new brakes and change the old ones．

       In the end, one   49   seems to be the solution   50   the problem．Sometimes the  51   idea comes quite  52  because the thinker suddenly sees something new or sees something in a          53   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  54   the brake．

       Finally the solution is  55  ．Sam does it and finds his bicycle works perfectly．In short, he has solved the problem．

People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a   21  problem. They often accept the opinion or ideas of other people. Other times they begin to act without   22 ；they try to find a solution by trial and error.   23  .，when all of these methods   24  ，the person with a problem has to start analyzing. There are six    25  in analyzing a problem.
   26  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 see that there is a problem with his bicycle.
Next the person must   27   the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must determine the parts that are wrong.
Now the person must look for   28  that will make the problem clearer and lead to  possible solutions. For example, suppose Sam   29   that his bike does not work because there is some thing wrong with the brakes(刹车).   30  , he can look in his bicycle repair book and read about brakes,   31  his friends at the bike shop, or look at his brakes carefully.
After studying the problem, the person should have   32  suggestions for a possible solution. Take Sam as an example   33 ，his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one   34  seems to be the solution to the problem. Sometimes the __35__ idea comes quite   36  because the thinker suddenly sees something new or sees something in a   37   way. Sam, for example, suddenly sees there is a piece of chewing gum（口香糖）stuck to a brake. He   38   finds the solution to his problem ：he must___39___the brake.
Finally the solution is tested .Sam finds that his bicycle   40  perfectly. In short he has solved the problem.
