A. It is very hard to break a code without the code book.

B. Only people who know the keyword can read the message.

C. As long as there have been codes, people have tried to break them.

D. You can hide a message by having the first letters of each word spell it out.

E. With a code book, you might write down words that would stand for other words.

F. Another way to hide a message is to use symbols to stand for specific letters of the alphabet.

    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. {#blank#}1{#/blank#}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. {#blank#}2{#/blank#}For example, the first letters of "My elephant eats too many eels" Spell out the hidden message "Meet me."

    {#blank#}3{#/blank#}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, 5, 20, 15, 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. {#blank#}4{#/blank#} For example, "bridge" might stand for "meet" and "out" might stand for "me."

Dear Miss Li,

    I'd like to thank you for giving money to "Animal Helpers", I'm sure you know that this group was set up to help people like me. You helped to make it possible for me to have Lucky. Lucky makes a big difference to my life. Let me tell you my story.

    What would it be like to be blind or deaf? Or imagine you can't walk or use your hands easily. Most people would never think about this, but many people have these difficulties, I can't use my arms or legs well, so normal things like answering the telephone, opening and closing doors or carrying things are difficult for me. Then one day last year, a friend of mine helped me out. She talked to Animal Helpers about getting me a special trained dog. She also thought a dog might cheer me up. I love animals and I was excited about the idea of having a dog.

    After six months of training with a dog at Animal Helpers, I was able to bring him home. My dog's name is Lucky—a good name for him because I feel very lucky to have him. You see, I'm only able to have a "dog-helper" because of your kindness! Lucky is very clever and understands many English words. He can understand me when I give him orders. For example, I say, "Lucky! get my book," and he does it at once.

    Lucky is a fantastic dog. I'll send you a photo of him if you like, and I could show you how he helps me. Thank you again for changing my life. Best wishes, Ben Smith

    Chogori(乔戈里峰)stands on the Chinese-Pakistan border. Chogori is from the Tajik language, it means" high, great and magnificent". Internationally, it is better known as K2. Chogori is about 8, 611 meters high, and it is the second highest mountain in the world.

    And Chogori is not Qomolangma. On the one hand, Chogori is a steeper(更陡峭的)and more dangerous peak. In fact, it is the most difficult peak to reach in the world. The first two people to reach the top of Chogori—Lino Lacedelli and Achille Compagnoni from Italy—did it in 1954. In 1986, the first woman did it too. Since 1954, only 281 people have reached the top, and 49 others have been killed (However, Qomolangma has been reached 3, 000 times and only 15 climbers lost their lives). Of all the over 8, 000-meter-high peaks, it has the highest death rate.

    On the other hand, this great peak is for professional climbers only. Here, no commercial(商业的)climbing organization will provide you any services, and even top-class climbers will choose their climbing partners with a particularly eagle(鹰)eye. The leader of a Japanese K2 team said when organizing his team in 1982, "We are professional climbers, and all know that if we run into trouble at a height of 8, 000 meters on K2, it is impossible to get help. If you do not have the confidence and determination(决心)to face possible trouble, you should not go!"

    This is Chogori! In the eyes of the top-class climbers, it is the most beautiful peak, and it is the danger that attracts them.
