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 thinking; they try to find a solution by trial and error． 37 , when all of these methods fail, the person with a problem has to start analyzing．There are six 38 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 39 that there is a problem with his bicycle． Next the person must 40 the problem．Before Sam can repair his bicycle, he must know why it does not work．For example, he must 41 the parts that are wrong． Now the person must look for 42 that will make the problem clearer and lead to 43 solutions．For example, suppose Sam decides that his bike does not work because there is something wrong with the brakes． 44 , he can look in his bicycle repair book and read about brakes, 45 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 to the problem．Sometimes the 50 idea comes quite 51 because the thinker suddenly sees something new or sees something in a 52 way．Sam, for example, suddenly sees there is a piece of chewing gum（口香糖）stuck to a brake．He 53 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． 小题1: A．usual B．serious C．similar D．common 小题2: A．Instead B．Besides C．Otherwise D．However 小题3: A．conditions B．ways C．stages D．orders 小题4: A．prove B．explain C．show D．see 小题5: A．find B．judge C．describe D．face 小题6: A．determine B．check C．correct D．recover 小题7: A．skills B．answers C．explanation D．information 小题8: A．exact B．possible C．real D．special 小题9: A．Once in a while B．In other words C．First of all D．At this time 小题10: A．talk to B．look for C．agree with D．depend on 小题11: A．settling down B．discussing C．comparing with D．studying 小题12: A．enough B．extra C．several D．countless 小题13: A．again B．secondly C．also D．alone 小题14: A．conclusion B．suggestion C．decision D．discovery 小题15: A．clear B．next C．final D．new 小题16: A．late B．unexpectedly C．clearly D．often 小题17: A．different B．simple C．quick D．sudden 小题18: A．easily B．fortunately C．clearly D．immediately 小题19: A．separate B．clean C．loosen D．remove 小题20: A．completed B．recorded C．tested D．accepted
