Code breaking never lags(落落后后) far behind code making.The science of creating and reading coded messages is called cryptography.牛刀小试1There are three main types of cryptography.37.(E.You can hide a message by having the first letters of each word spell it out.) For example，the first letters of “My elephant eats too many eels” spell out the hidden message “Meet me.”38.(G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet.)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.(F.With a code book，you might write down words that would stand for other words.) 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.A.It is very hard to break a code without the code book.B.In any language，some letters are used more than others.C.Only people who know the keyword can read the message.D.As long as there have been codes，people have tried to break them.E.You can hide a message by having the first letters of each word spell it out.F.With a code book，you might write down words that would stand for other words.G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet. 答案解析 (2017全国全国，片段，片段)We slept in a tent，cooked over an open fire，and walked a long distance to take the shower and use the bathroom.This brief visit with Mother Nature cost me two days off from work，recovering from a bad case of sunburn and the doctors bill for my sons food poisoning.I was，nevertheless，talked into going on another fun-filled holiday in the wilderness. 38 Instead，we had a pop-up camper with comfortable beds and an air conditioner.My nature-loving friends had remembered to bring all the necessities of life. 二、语意判断典例2解解析析 根根据据前前文文“We slept in a tent.”可可知知作作者者第第一一次次露露营营时时住住帐帐篷篷，而而后后文文中中“Instead，we had a pop-up camper with comfortable beds and an air conditioner.”说说明明作作者者这这次次露露营营有有床床有有空空调调。由由此此可可知知，这这次次没有帐篷了。故选没有帐篷了。故选A。A.This time there was no tent.B.Things are going to be improved.C.The trip they took me on was a rough one.D.I was to learn a lot about camping since then，however.E.I must say that I have certainly come to enjoy camping.F.After the trip，my family became quite interested in camping.G.There was no shade as the trees were no more than 3 feet tall.答案解析点津点津七七选选五五解解题题时时要要读读懂懂前前后后文文的的句句子子，弄弄清清楚楚前前后后的的逻逻辑辑关关系系，然然后后选选取取正正确确答答案案，因因此此正正确确理理解解设设空空前前后后文文是是解解题题的的关关键键，拿拿到到试试题题后后要要瞻前顾后，科学解题。瞻前顾后，科学解题。(2016全国全国，片段，片段)People have used secret codes for thousands of years. 36 Code breaking never lags(落落后后) far behind code making.A.It is very hard to break a code without the code book.B.In any language，some letters are used more than others.C.Only people who know the keyword can read the message.D.As long as there have been codes，people have tried to break them.E.You can hide a message by having the first letters of each word spell it out.F.With a code book, ,you might write down words that would stand for other words.G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet. 牛刀小试2答案解析 (2017全国全国，片段，片段) 37 We slept in a tent，cooked over an open fire，and walked a long distance to take the shower and use the bathroom.A.This time there was no tent.B.Things are going to be improved.C.The trip they took me on was a rough one.D.I was to learn a lot about camping since then，however.E.I must say that I have certainly come to enjoy camping.F.After the trip，my family became quite interested in camping.G.There was no shade as the trees were no more than 3 feet tall. 三、黄金三步骤典例3答案解析点津点津步步骤骤一一：从从原原文文设设空空的的前前后后寻寻找找关关键键词词；步步骤骤二二：阅阅读读各各个个选选项项，标标记关键词；步骤三：把两类关键词进行匹配，迅速锁定正确答案。记关键词；步骤三：把两类关键词进行匹配，迅速锁定正确答案。(2016全国全国，片段，片段)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.”A.It is very hard to break a code without the code book.B.In any language，some letters are used more than others.C.Only people who know the keyword can read the message.D.As long as there have been codes，people have tried to break them.E.You can hide a message by having the first letters of each word spell it out.F.With a code book, ,you might write down words that would stand for other words.G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet. 牛刀小试3答案解析 (2017全国全国，片段，片段)39.(F.After the trip，my family became quite interested in camping.)
