Passage 1(2016全国Ⅰ)
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Secret codes (密码)keep messages private.Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.
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. Let’s 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 “135520135.”
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.
【语篇导读】 这是一篇说明文。向读者介绍了密码在生活中的作用及密码学的三种基本类型。
1．D[考查综合分析能力。联系下一句的意思，“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。]
2．E[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。]
3．G[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。]
4．F[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。]
5．A[考查综合分析能力。由下文中的“also hard”二词可知答案非A莫属。]

【语篇导读】 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。
1．F[本题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可知，你是否参观过一个美丽的花园，再结合后面的It starts with looking inside yourself可知，故F项“你也可以把自己的花园弄得这么漂亮”符合语境。]
2．A[本题考查综合分析能力。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。]
3．E[本题考查综合分析能力。前两句谈到有些人认为花园只是一些花花草草，有些人关心的是少用水少用肥料的方法。本句应该仍然是人们对园艺的不同看法。故E项“还有其他人只是喜欢在户外接触植物”与上下文一致。]
4．C[本题考查运用语境进行推断的能力。根据前面的that’s not what’s 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。]
5．G[本题考查综合分析能力。这里介绍的是自己弄一个花园，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。]
