(2016·新课标全国卷I) 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 ofMy elephant eats too many eelsspell out the hidden messageMeet 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 messageMeet mewould read135 520 135.

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 formeetandout might stand forme.The messageBridge outwould actually meanMeet 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. nother way to hide a message is to use symbols to stand for specific letters of the alphabet.
