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.AIt is very hard to break a code without the code book.BIn any language，some letters are used more than others.COnly people who know the keyword can read the message.DAs long as there have been codes, people have tried to break them.EYou can hide a message by having the first letters of each word spell it out.F
