Do you go to school every day by bike or in your parents' car? The American English teacher Margaret told her story about taking a school bus in America:

When I was a primary school student, I loved taking the school bus. It was interesting to talk to my friends and play games on the bus. It was like children-only party every morning and afternoon. On the school bus there was only one adult(成年人)—the driver. Most of the time, we were well-behaved because we liked the driver and didn't want to make him unhappy. But one day, one of the boys made a face (做鬼脸) at a policeman(警察) driving behind our bus. The policeman made our bus drive stop. Then he scolded(训斥) the naughty boy loudly. We were all very good after that!

    It wasn't comfortable for young people to wait for the school bus in winter because it was very cold, especially when there were strong winds. Some students in cities had bus shelters(遮挡), but country children had to jump up and down to warm up. Hurry up, spring!

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." The message "bridge out" would actually mean "Meet me." {#blank#}5{#/blank#} However, it is also hard to keep a code book secret for long. So codes must be changed frequently.

    A good book can be satisfying, can improve your knowledge and can teach you a lot. There are several ways to develop a lifetime reading habit.

    Set times. You should have a few set times every day when you'll read for at least 5—10 minutes, no matter what happens. For example, make it a habit to read during breakfast and lunch (and even dinner if you eat alone).

    Always carry a book. No matter where you go, take a book with you. When you leave the house, make sure to have at least one book. You may keep the book in the car, or into the office or to anywhere you go, unless you' re sure you won't have time to read.

    Make a list. Keep a list of all the great books you want to read. You can keep this in a pocket notebook. Be sure to add to it whenever you hear about a good book. Keep a running list, and cross out the ones you have read.

    Find a quiet place. Find a place in your home where you can sit in a comfortable chair without television or computer near the chair. There should be no music or noisy family members.

    Set a high aim. For example. Tell yourself that you want to read 50 books this year. Your best to finish reading them. Just be sure you're still enjoying the reading.

    Last summer holiday I went to Taiwan with my parents. Taiwan is really beautiful! The weather is good. It is always warm and humid(潮湿的) because the sea is around Taiwan. In the north, there is winter, but in the south, there's no winter and you can enjoy sunshine(阳光). The typhoon(台风) season is from June to September.

    There are many mountains in Taiwan. Ali Mountain is one of the biggest mountains there. We went to climb Ali Mountain one afternoon. There are many trees in the forest there. They are very tall and many of them are really old.

    Sun Moon Lake is the largest natural lake in Taiwan. In the lake there are many kinds of fishes.

    We also went to the beach and enjoyed the sunshine. There are many kinds of foods in the small towns near the sea. A kind of dumplings with shrimps(虾) in them is my favourite.

    Taiwan is a beautiful island. I love it! I took many photos there. Would you love to see them?
