parents, mine were hard to”，下文的“so I figured this was a great opportunity to get them something”以及接下来介绍的作者兄弟姊妹几人为父母买礼物的内容可知，此处指作者觉得给父母买东西是很难的，故选shop“购物”。3B根据上文的“Dad mentioned hed always wanted a Crimson King Maple Tree for the yard.”及下文介绍的为父母买礼物的内容可知，此处指作者认为这是一个给父母买他们欣赏的东西的好机会。deserve“值得，应得”；appreciate“感激，欣赏”；advertise“为做广告”；imagine“想象”。4C根据下文的“but all of my siblings(兄弟姊妹)agreed to give some money to buy the trees”可知，作者在上班时查看了一下枫树的价格(price)，认为它的价格比自己能支付得起(afford)的还要高一点。express“快递”。5A参见上题解析。6C从下文作者联合其姑姑来帮忙实施这个计划以及计划具体实施的内容可知，作者他们想给父母一个惊喜(surprise)。assist“帮助，协助”。7B根据上下文语境及句中的“In northern Ohio, you dont plant maple trees at Christmas”“a special Christmas in October before the ground”可知，作者他们决定在土地上冻之前让父母度过一个特别的圣诞节。freeze“结冰”符合语境。soften“变软，软化”。8A根据上下文语境可知，作者询问姑姑是否可以帮忙实施这个“骗局(trick)”。9A根据上下文语境可知，作者的姑姑提前(in advance)给作者的父母打电话说她会在周日来拜访。in time“及时”；by accident“意外地”；on purpose“故意地”。10B根据下文的“planning a big holiday turkey dinner”可知，随后，作者的姊妹和嫂子(或弟媳)行动起来。go into action“行动起来”符合语境。go into service“投入使用”；go into effect“生效”；go into production“投产”。11D根据语境可知，作者和亲人们在选定的(chosen)那个周日聚到自己家里。regular“惯常的，有规律的”。12B根据下文的“the trees into a truck”可知，作者他们把树装上(loaded)卡车。transport“运输，运送”；transplant“移植”。13A根据下文的“as Santa Claus”可知，作者把自己装扮(dressed up)成圣诞老人。pass sb./sth.off as“把冒充为”；look on sb./sth.as“把当做”；start out as“以开始，起初是”。14D根据上下文语境及句中的“something was wrong first”可知，作者的父亲一开始坚信哪里出了问题。convinced“确信，坚信”符合语境。15C根据语境可知，当我们告诉他们我们为什么(why)会在那里的时候，父母感到很吃惊。16A根据下文的内容可知，当又到圣诞节时，作者他们去探望父母。e around“再次出现，再度发生”；drop out“退出”；turn up“出现”；draw in“(白天变得)渐短”。17C根据上文的“In northern Ohio, you dont plant maple trees at Christmas so we decided to.with a special Christmas in October”可知，作者他们在十月份的时候已经为父母送上了一份特别的圣诞节礼物，而在真正的圣诞节到来的时候，他们又不能空手去拜访自己的父母，故作者的父母那年是收到了双份的(double)圣诞节礼物。additional“额外的”。18D根据上下文语境可知，时隔几乎半个世纪之后，当作者看到那些高大、漂亮的枫树(trees)时依然(still)会面带微笑地驶过那个农场。19B参见上题解析。20B作者看着那些枫树时，会想起自己多年前在特别的圣诞节送给父母特别的礼物(gift)。上文中的“presents that year”亦是关键提示。donation“捐赠物”；greeting“问候”。四、七选五。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. 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. 【语篇解读】本文是一篇说明文，主要介绍了密码的设置和破解的方法。比如利用该字母在字母表中排序的数字来代表该字母，或者利用一些单词的首字母来组成一个密码等。1.D 【解题思路】根据后面一句Code breaking never lags(落后) far behind code making可知，此空该选D(只要有密码的存在，人们就会试图去破解它们)。2.E 【解题思路】根据后一句的For example, the first letters of My elephant eats too many eels spell out the hidden message Meet me.可知，此空该选E(你可以拼写每个单词的第一个字母来隐藏信息)。3.G 【解题思路】上一段介绍了第一种密码类型，本段介绍的是第二种类型，再根据空后的内容可知，空处选G(另外一种隐藏信息的方式是用符号来代表字母表中的特定字母)。4.F 【解题思路】由前一句的a code book和空后的bridgemight stand for.me.可知，此空该选F(有了密码书，你就可以写下代表其他单词的单词)。5.A 【解题思路】本段介绍的是密码书，根据空后的转折可知，此处该选A(没有密码书是很难破解密码的)。
