2019-2020年高考英语二轮复习考前三个月专题二七选五精研高考真题寻找解题规律真题演练一(xx全国)Secret codes(密码) keep messages private.Banks，panies，and government agencies use secret codes in doing business，especially when information is sent by puter.People have used secret codes for thousands of years. 36 Code breaking never lags(落后) far behind code making.The science of creating and reading coded messages is called cryptography.There are three main types of cryptography. 37 For example，the first letters of “My elephant eats too many eels” spell out the hidden message “Meet me.” 38 You might represent each letter with a number，for example.Lets number the letters of the alphabet，in order，from 1 to 26.If we substitute a number for each letter，the message “Meet me” would read “13 5 5 20 13 5.” A code uses symbols to replace words，phrases，or sentences.To read the message of a real code，you must have a code book. 39 For example，“bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me.” 40 However，it is also hard to keep a code book secret for long.So codes must be changed frequently.AIt is very hard to break a code without the code book.BIn any language，some letters are used more than others.COnly people who know the keyword can read the message.DAs long as there have been codes，people have tried to break them.EYou can hide a message by having the first letters of each word spell it out.FWith a code book，you might write down words that would stand for other words.GAnother way to hide a message is to use symbols to stand for specific letters of the alphabet.36答案D解析考查综合分析能力。联系下一句“创设密码和破译密码总是相伴而生的”，可以推断此处意思是“只要有密码存在，人们总是千方百计地进行破译”。故选D项。37答案E解析考查联系上下文的能力。依据接下来的举例可知，这里讲的是选取每个单词的首字母这一方法来隐藏信息。因此答案为E。38答案G解析考查运用语境进行推断的能力。前文已经介绍了一种设置密码的方式，这里又介绍了另一种。故选G。G项中的another也是解题的关键标志词。39答案F解析考查联系上下文的能力。空格前的a code book暗示答案可能为F项，通过验证，两句意思通顺自然，衔接紧密。故答案为F。40答案A解析考查综合分析能力。分析语境可知，该处仍在谈论密码本，由此可锁定A项，该句与空后一句衔接紧密，可确定为答案。B(xx全国)A Garden Thats Just Right for YouHave you ever visited a garden that seemed just right for you，where the atmosphere of the garden appeared to total more than the sum(总和) of its parts？ 36 .But it doesnt happen by accident.It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process. 37 Some people may think that a garden is no more than plants，flowers，patterns and masses of color.Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料) 38 .However，there are a number of other reasons that might explain why you want to garden.One of them es from our earliest years.Recall(回忆) your childhood memoriesOur model of what a garden should be often goes back to childhood.Grandmas rose garden and Dads vegetable garden might be good or bad，but thats not whats important. 39 how being in those gardens made us feel.If youd like to build a powerful bond with your garden，start by taking some time to recall the gardens of your youth. 40 .Then go outside and work out a plan to translate your childhood memories into your grownup garden.Have fun.AKnow why you gardenBFind a good place for your own gardenCIts our experience of the garden that mattersDIts delightful to see so many beautiful flowersEStill others may simply enjoy being outdoors and close to plantsFYou can produce that kind of magical quality in your own garden，tooGFor each of those gardens，write down the strongest memory you have语篇解读这是一篇说明文。主要介绍的是如何做园艺，让美丽的花园给我们带来美好的视觉享受。36答案F解析考查联系上下文的能力。根据前面的“Have you ever visited a garden that seemed just right for you”，再结合后面的“It starts with looking inside yourself”可知，F项“你也可以使自己的花园产生那样一种魔力”符合语境。37答案A解析考查子标题。根据后面的“there are a number of other reasons that might explain why you want to garden”可知，这一部分主要说明的是首先要弄清楚从事园艺的原因。故A项与之相符。38答案E解析考查联系上下文的能力。根据上文中的“Some people may think.”和“Others are concerned about.”可知，此处表达的是人们搞园艺的不同原因，而E项中的“Still others may simply enjoy.”与上下文衔接自然，故选E项。39答案C解析考查运用语境进行推断的能力。根据前面的“thats not whats important”可知，这里强调的是在园艺中对我们来说真正重要的是什么。故C项“重要的是我们搞园艺的经历”符合上下文语境。40答案G解析考查综合分析能力。这里介绍的是自己建设一个花园，要回忆一下年轻时所看到的那些花园，并把这些花园的优点写下来，然后制定计划并去践行。故G项与上下文一致。C(xx全国)Everyone knows that fish is good for health. 36

cooking fish isnt difficult. 37 This text is about how to buy and cook fish in an easy way. 38 Fresh fish should smell sweet: you should feel that youre standing at the oceans edge.Any fishy or strong

disease.36答案G解析根据该空内容的前一句和后面的but 可知该空内容应是吃鱼的好处，故判断G选项符合语境。37答案D解析空格前说“买鱼、储藏鱼、做鱼并不难”，空格后说“本文就是关于如何买鱼并用一种简单方法做鱼的”。综观各选项，D项“这只需要一点儿知识”与上下文语意衔接紧密，故为答案。38答案F解析本段第二、三句讲了如何通过嗅觉来鉴别鱼是否新鲜，故F选项符合语境。39答案A解析此句是对上文的一个总结，根据因果关系，故选A选项。40答案B解析根据空前内容可知此处应填做鱼的方法，再结合文中的“a steam pot”可知，B选项符合语境。D(xx北京)The Science of RiskSeekingSometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward，the risk seems worth taking. 71 Some of us enjoy activities that would surprise and scare the rest of us.Why? Experts say it may have to do with how our brains work.The reason why any of us take any risks at all might have to do with early humans.Risktakers were better at hunting，fighting，or exploring. 72 As the quality of risktaking was passed from one generation to the next，humans ended up with a sense of adventure and a tolerance for risk.So why arent we all jumping out of airplanes then? Well，even 200,000 years ago，too much risktaking could get one killed.A few daring survived，though，along with a few stayinthecave types.As a result，humans developed a range of character types that still exists today.So maybe you love car racing，or maybe you hate it. 73 No matter where you are on the riskseeking range，scientists say that your willingness to take risks increases during your teenage years. 74 To help you do that，your brain increases your hunger for new experiences.New experiences often mean taking some risks，so your brain raises your tolerance for risk as well. 75 For the riskseekers，a part of the brain related to pleasure bees active，while for the rest of us，a part of the brain related to fear bees active.As experts continue to study the science of riskseeking，well continue to hit the mountains，the waves or the shallow end of the pool.AIt all depends on your character.BThose are the risks you should jump to take.CBeing better at those things meant a greater chance of survival.DThus，these wellequipped people survived because they were the fittest.EThis is when you start to move away from your family and into the bigger world.FHowever，we are not all using the same reference standard to weigh risks and rewards.GNew brain research suggests our brains work differently when we face a nervous situation.语篇解读本文是一篇议论文。生活中人们对冒险的态度各不相同，有些人热爱冒险，有些人却避而远之。专家说这是因为我们的大脑工作方式不同。另外，科学研究表明，这些表现也与人类的早期活动有关。71答案F解析根据空前面的“weigh the risk and the reward”可以看出和F项中的“weigh risks and rewards”对应，同时F项与空格前面的一句话之间是转折关系，句意衔接紧密，故选F项。72答案C解析根据空前面的“better at hunting，fishing，or exploring”可以看出和C项中的“Being better at those things”相呼应。故选C项。73答案A解析空格前第二句中出现character types与A选项中的character相对应；空格前一句中的you 与选项中的your在人称上保持一致；空格前一句中动词love与hate和A选项中的depends on对应，故选A项。74答案E解析空格前一句出现了teenager years 与E选项当中的this 相对，另外E选项当中提到“move away from family into the bigger world”也是对空格前一句中的teenager years的解释。故选E项。75答案G解析空格后一句中提及pleasure和fear，是从正反两方面进行对比，对应G项中的differently，再根据空格后一句中出现的riskseeker，brain，us等词与选项G中的nervous situation，our brains相对应，故选G项。
