2019年高考英語(yǔ)一輪復(fù)習(xí) 第一部分 教材課文要點(diǎn) Module 4 Sandstorms in Asia語(yǔ)篇解題微技巧 外研版必修3推斷句題(七選五)方法指導(dǎo)在七選五中對(duì)推斷句的考查主要包括兩個(gè)層面。1)段中推斷句:做題時(shí)閱讀空格前后的相鄰內(nèi)容,抓住體現(xiàn)邏輯關(guān)系的信號(hào)詞(thus、therefore、however等),確定上下文并列、遞進(jìn)、轉(zhuǎn)折、因果等關(guān)系。2)段尾推斷句:閱讀前文,鎖定高頻詞或體現(xiàn)邏輯關(guān)系的信號(hào)詞并且注意與下一段開頭的銜接關(guān)系。典例引領(lǐng) (xx課標(biāo))根據(jù)短內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩處為多余選項(xiàng)。Secret codes(密碼)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.1Code 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.2For example, the first letters of “My elephant eats too many eels”spell out the hidden message“Meet me.” 3You 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.4For example, “bridge”might stand for “meet”and“out”might stand for “me”.The message“Bridge out”would actually mean“Meet me.”5However, 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.方法運(yùn)用 語(yǔ)篇解讀本文是一篇說(shuō)明文。介紹了密碼的用途、歷史以及三種密碼方式。1.D過(guò)渡句。上句提到:人們使用密碼已經(jīng)幾千年了。下句提到:密碼的破解從未太落后于密碼的設(shè)定。由此可知D項(xiàng)符合語(yǔ)境,意為“只要有密碼,人們就會(huì)盡力去破解它們?！?.E過(guò)渡句。上句提到:有三種主要的密碼設(shè)定方式。下句提到:例如,“My elephant eats too many eels”的首字母就拼出了“Meet me”這一隱藏起來(lái)的信息。由此可知本句應(yīng)該為一種密碼的設(shè)定方式,根據(jù)下句舉到的例子,可知E項(xiàng)正確,意為“你可以用每個(gè)單詞的首字母拼寫出一條信息,以此來(lái)隱藏它?！?.G主旨句。上段指出有三種主要的密碼設(shè)定方式,上段已經(jīng)提到了一種,本段應(yīng)該指出另外一種。下文舉例說(shuō)明了用數(shù)字來(lái)代替字母的密碼方式,由此可知G項(xiàng)能起到統(tǒng)領(lǐng)本段的作用,意為“另外一種隱藏信息的方式就是用符號(hào)來(lái)代替字母表中特定的字母?！?.F細(xì)節(jié)句。上句指出:要解讀某個(gè)真實(shí)密碼的信息,你必須要有密碼本。本句是對(duì)上句的解釋說(shuō)明,結(jié)合下文舉到的例子,可推斷出本句主要解釋如何利用密碼本來(lái)破解隱藏起來(lái)的信息。F項(xiàng)符合語(yǔ)境,意為“擁有了密碼本,你也許就能寫出代表其他單詞的單詞。”5.A細(xì)節(jié)句。上文指出了利用密碼本來(lái)破解密碼的方式。A項(xiàng)是總結(jié)上文內(nèi)容得出的結(jié)論,意為“沒有密碼本就很難破解密碼”,而且根據(jù)下句“.it is also hard to.”的句型結(jié)構(gòu)也可得知A項(xiàng)符合語(yǔ)境。
