handsome”，故此處應(yīng)是母親也欣然同意，認(rèn)為楓樹很漂亮(pretty)。distinctive“與眾不同的”；fragrant“芳香的”。2A根據(jù)上文的“Like many other parents, mine were hard to”，下文的“so I figured this was a great opportunity to get them something”以及接下來介紹的作者兄弟姊妹幾人為父母買禮物的內(nèi)容可知，此處指作者覺得給父母買東西是很難的，故選shop“購物”。3B根據(jù)上文的“Dad mentioned hed always wanted a Crimson King Maple Tree for the yard.”及下文介紹的為父母買禮物的內(nèi)容可知，此處指作者認(rèn)為這是一個(gè)給父母買他們欣賞的東西的好機(jī)會。deserve“值得，應(yīng)得”；appreciate“感激，欣賞”；advertise“為做廣告”；imagine“想象”。4C根據(jù)下文的“but all of my siblings(兄弟姊妹)agreed to give some money to buy the trees”可知，作者在上班時(shí)查看了一下楓樹的價(jià)格(price)，認(rèn)為它的價(jià)格比自己能支付得起(afford)的還要高一點(diǎn)。express“快遞”。5A參見上題解析。6C從下文作者聯(lián)合其姑姑來幫忙實(shí)施這個(gè)計(jì)劃以及計(jì)劃具體實(shí)施的內(nèi)容可知，作者他們想給父母一個(gè)驚喜(surprise)。assist“幫助，協(xié)助”。7B根據(jù)上下文語境及句中的“In northern Ohio, you dont plant maple trees at Christmas”“a special Christmas in October before the ground”可知，作者他們決定在土地上凍之前讓父母度過一個(gè)特別的圣誕節(jié)。freeze“結(jié)冰”符合語境。soften“變軟，軟化”。8A根據(jù)上下文語境可知，作者詢問姑姑是否可以幫忙實(shí)施這個(gè)“騙局(trick)”。9A根據(jù)上下文語境可知，作者的姑姑提前(in advance)給作者的父母打電話說她會在周日來拜訪。in time“及時(shí)”；by accident“意外地”；on purpose“故意地”。10B根據(jù)下文的“planning a big holiday turkey dinner”可知，隨后，作者的姊妹和嫂子(或弟媳)行動起來。go into action“行動起來”符合語境。go into service“投入使用”；go into effect“生效”；go into production“投產(chǎn)”。11D根據(jù)語境可知，作者和親人們在選定的(chosen)那個(gè)周日聚到自己家里。regular“慣常的，有規(guī)律的”。12B根據(jù)下文的“the trees into a truck”可知，作者他們把樹裝上(loaded)卡車。transport“運(yùn)輸，運(yùn)送”；transplant“移植”。13A根據(jù)下文的“as Santa Claus”可知，作者把自己裝扮(dressed up)成圣誕老人。pass sb./sth.off as“把冒充為”；look on sb./sth.as“把當(dāng)做”；start out as“以開始，起初是”。14D根據(jù)上下文語境及句中的“something was wrong first”可知，作者的父親一開始堅(jiān)信哪里出了問題。convinced“確信，堅(jiān)信”符合語境。15C根據(jù)語境可知，當(dāng)我們告訴他們我們?yōu)槭裁?why)會在那里的時(shí)候，父母感到很吃驚。16A根據(jù)下文的內(nèi)容可知，當(dāng)又到圣誕節(jié)時(shí)，作者他們?nèi)ヌ酵改浮 around“再次出現(xiàn)，再度發(fā)生”；drop out“退出”；turn up“出現(xiàn)”；draw in“(白天變得)漸短”。17C根據(jù)上文的“In northern Ohio, you dont plant maple trees at Christmas so we decided to.with a special Christmas in October”可知，作者他們在十月份的時(shí)候已經(jīng)為父母送上了一份特別的圣誕節(jié)禮物，而在真正的圣誕節(jié)到來的時(shí)候，他們又不能空手去拜訪自己的父母，故作者的父母那年是收到了雙份的(double)圣誕節(jié)禮物。additional“額外的”。18D根據(jù)上下文語境可知，時(shí)隔幾乎半個(gè)世紀(jì)之后，當(dāng)作者看到那些高大、漂亮的楓樹(trees)時(shí)依然(still)會面帶微笑地駛過那個(gè)農(nóng)場。19B參見上題解析。20B作者看著那些楓樹時(shí)，會想起自己多年前在特別的圣誕節(jié)送給父母特別的禮物(gift)。上文中的“presents that year”亦是關(guān)鍵提示。donation“捐贈物”；greeting“問候”。四、七選五。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. 1 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. 2 For example, the first letters of My elephant eats too many eels spell out the hidden message Meet me. 3 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. 4 For example, bridge might stand for meet and out might stand for me. The message Bridge out would actually mean Meet me. 5 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. 【語篇解讀】本文是一篇說明文，主要介紹了密碼的設(shè)置和破解的方法。比如利用該字母在字母表中排序的數(shù)字來代表該字母，或者利用一些單詞的首字母來組成一個(gè)密碼等。1.D 【解題思路】根據(jù)后面一句Code breaking never lags(落后) far behind code making可知，此空該選D(只要有密碼的存在，人們就會試圖去破解它們)。2.E 【解題思路】根據(jù)后一句的For example, the first letters of My elephant eats too many eels spell out the hidden message Meet me.可知，此空該選E(你可以拼寫每個(gè)單詞的第一個(gè)字母來隱藏信息)。3.G 【解題思路】上一段介紹了第一種密碼類型，本段介紹的是第二種類型，再根據(jù)空后的內(nèi)容可知，空處選G(另外一種隱藏信息的方式是用符號來代表字母表中的特定字母)。4.F 【解題思路】由前一句的a code book和空后的bridgemight stand for.me.可知，此空該選F(有了密碼書，你就可以寫下代表其他單詞的單詞)。5.A 【解題思路】本段介紹的是密碼書，根據(jù)空后的轉(zhuǎn)折可知，此處該選A(沒有密碼書是很難破解密碼的)。
