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 thinking；they try to find a solution by trial and error._2_，when all of these methods fail，the person with a problem has to start analyzing.There are six _3_ in analyzing a problem._4_ the person must recognize that there is a problem.For example，Sams bicycle is broken，and he cannot ride it to class as he usually does.Sam must _5_ that there is a problem with his 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 _6_ the parts that are wrong.Now the person must look for _7_ that will make the problem clearer and lead to _8_ solutions.For example，suppose Sam decides that his bike does not work because there is something wrong with the brakes._9_，he can look in his bicycle repair book and read about brakes，_10_ his friends at the bike shop，or look at his brakes carefully.After _11_ the problem，the person should have _12_ suggestions for a possible solution.Take Sam as an example _13_，his suggestions might be：tighten or loosen the brakes；buy new brakes and change the old ones.In the end，one _14_ seems to be the solution to the problem.Sometimes the _15_ idea comes quite _16_ because the thinker suddenly sees something new or sees something in a _17_ 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.1A.seriousBusualCsimilarDcommon2A.BesidesBInsteadCOtherwiseDHowever3A.waysBconditionsCstagesDorders4A.FirstBUsuallyCIn generalDMost

they here now，they could help us.If they were here now，they could help us.如果他们现在在的话，就会帮助我们了。(2)Had you come earlier，you would have met him.If you had come earlier，you would have met him.如果你来得早一点，就会碰到他了。(3)Should it rain，the crops would be saved.If it should rain，the crops would be saved.如果下雨，庄稼就有救了。 答案.1.should get；would be expected2.would ask；were3.had come；would have seen4.could finish5.would show；were6.had stayed 7Were；would be saved8.rains.1.break the habit of staying up too late2.Make sure3.is famous as4.let alone5.dreamed of becoming6.The reason why he was absent.1.some；day2.as；carefully；as；possible3.as；cool；as；a；cucumber4.Had；trained；failed 5provided/supplied；with .1.A由从句的谓语形式were to do及从句时间状语tomorrow可知主句表示与将来事实相反的假设，故谓语用“should动词原形”。2B表示与过去事实相反时，从句中谓语用过去完成式，主句谓语用“would/could/mighthave动词过去分词”。3C本题考查与现在事实相反的虚拟语气。条件句中的if省略了，完整的句子是：If I were rich.。条件句中，如果是be的形式，不管主语是单数还是复数，都用were。4B本题考查与过去事实相反的虚拟语气。条件句中的if省略了，完整的句子是：If the captain had been more careful. 。省略if时应将had提至句首。5B句意为：要是我做这件事，我会用另一种方法。表示与将来事实相反，主句谓语用“would/should/could/might动词原形”。6B第二句的主句谓语为would have said，可知虚拟语气表述的是与过去事实相反的愿望，因此从句的谓语用过去完成时，故答案为B项。7C由问句可知，时态为一般现在时，故答句是对现在情况的虚拟，应用一般过去时，be动词用were，故选C项。8A句意为：汤姆不在这里，如果他来了的话我们会更高兴的。由句意和would可知题干用了虚拟语气，而且是对现在情况的虚拟，所以if从句用过去式。9C根据句子意思，这是与将来事实相反的虚拟语气，所以选C项。10B句意为：文章中他写的内容一般读者不知道。此题考查连词引导主语从句，主语从句中连词的使用关键要以连词在从句中所起的作用而定。此主语从句中referred to后面明显缺宾语，所以应该选连接代词，故C、D两项被排除；that在从句中不充当成分，故选B项。.1.C从上文的提示“try to remember a solution from the last time”，表明人们一旦遇上类似的问题，首先想到的是上次碰到这类问题的解决办法。2D下文用however表示转折，表明作者观点：有时靠老办法往往不灵，于是人们便开始分析问题，寻找新的解决途径。3C从下文的列举看，作者讲的是解决问题的六个阶段，且层层深入，而不是在阐述解决问题的六个办法、条件、顺序。4A下文next，finally等表明作者在列举分析问题、解决问题的几个步骤，故填first(首先)，与下文呼应。5D作为分析的第一步，Sam必须查看自行车的毛病出在哪儿。see在此的含义是：examine or recognize by looking。6Bdetermine在这里意为“断定，确定”的意思，因为只有确定哪个部分有问题，才会找到针对性的解决办法。下文也有暗示，用了同义词decide。7D
