Dear Sir or Madam,
I've learned that an art exhibition is (hold) and that you're collecting suggestions on its location. I'm writing this letter to share you my opinions.

Secret codes (密碼)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. 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. For example, the first letters of “My elephant eats too many eels” Spell out the hidden message “Meet me.”
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 “13 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. For example “bridge“ might stand for “meet” and “out” might stand for “me.” The message “bridge out” would actually mean “Meet me.” 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.
