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 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. 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 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.
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.
If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me. 1.
The friends who introduced me to camping thought that it meant to be a pioneer. 2. We slept in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.
I was, nevertheless, talked into going on another fun-filled holiday in the wilderness. 3. Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.
4. We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.
5. It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.
A. This time there was no tent.
B. Things are going to be improved.
C. The trip they took me on was a rough one.
D. I was to learn a lot about camping since then, however.
E. I must say that I have certainly come to enjoy camping.
F. After the trip, my family became quite interested in camping.
G. There was no shade as the trees were no more than 3 feet tall.
Disneyland calls itself the happiest place in the world, but to keep visitors happy in its five locations across the globe, each theme park is adjusted to cater to local cultures and tastes. Outside of the two original resort areas in the US, Disneyland in California and Walt Disney World in Florida, the Disneylands in Paris, Tokyo and Hong Kong offer subtly different layouts to make their millions of visitors each year feel at home.
Disneyland Paris
After excitedly entering Disneyland Paris, which opened in 1992, visitors are greeted with an arcade(拱廊) that features a small replica(复制品) of the Statue of Liberty—a gift from France to the US in 1886, making it a fitting introduction to Europe’s only instance of this American theme park. The arcade also offers essential cover from the cold and rain that typically hit Paris.
As you venture further into Disneyland Paris, you will see a lot of European visionaries, such as Leonardo da Vinci with the Orbitron attraction, a unique theater show featuring French director and actress Julie Delpy on screen with synchronized live actors, and the character Remy, a French chef rat from the Disney cartoon Ratatouille with an attached restaurant to match the cartoon's fine-dining kitchen.
Tokyo Disneyland
Opened in 1983, Tokyo Disneyland is the third most visited of any theme park in the world after the two Disney parks in the US. Like Walt Disney World in Florida, Cinderella’s Castle is located at the center of the park, said to have been chosen because the princess's qualities of duty and a strong work ethic would resonate more deeply in Japanese culture than Sleeping Beauty, whose castle is featured in the center of Disneyland California.
Hong Kong Disneyland
The Hong Kong Disneyland, opened in 2005, incorporates feng shui and traditional Chinese elements into its design to attract tourists from the Chinese mainland.
Feng shui balances the elements of wood, fire, earth, metal and water to create positive energy, and these elements can be seen throughout the theme park. Rocks represent stability and prevent good luck from flowing away, so two gigantic boulders have been placed at the park's entrance to stop energy from flowing out of the resort. Water stimulates fortune and wealth, and the theme park is full of lakes, ponds and streams—not to mention the large fountain featuring Disney characters placed at the main entrance of the park.
1.From the text, we can conclude that in Disneyland Paris ________.
A. the arcade is a symbol of friendship between France and the US
B. there is a theater that shows the popular Disney cartoon Ratatouille
C. a theater shows famous French characters in great movies in different times
D. the Statue of Liberty replica reflects Disneyland's status as the latest moment in the historical relationship between France and the US
2.The text discusses how Hong Kong Disneyland ________.
A. is the oldest Disney theme park outside of America
B. has deep connections with traditional Chinese culture
C. has two boulders at the entrance to bring in good luck
D. provides many water-related entertainment activities
3.The main purpose of the text is to ________.
A. offer visitors some money-saving tips for visiting Disneyland theme parks
B. show how Disneyland parks outside of the US are adjusted to local people’s tastes
C. show the development of Disneyl and theme parks around the world throughout history
D. tell visitors how to enjoy themselves at Disneyland theme parks
(2016·上杭模拟)For many years, people around the world were crazy about a boy with blond hair. And perhaps these times have returned, as a new movie version of classic The Little Prince has been released in many countries. It came out in China on Oct. 16. Now we have an opportunity to look again at what has made this boy so popular with so many people of all ages, all over the world since the novel’s first publication in 1943.
A pilot crashes his plane in the desert. In this terrible situation he meets the Little Prince, who is a strange being from an asteroid(小行星). We learn that the Prince has been on a long journey. He left his home after an unhappy love affair. This love affair wasn't with another of the Prince's kind, but with a beautiful rose. Looking for a way to mend his broken heart, he toured planets looking for wisdom.
He met many different beings, but all were foolish and disappointed the Prince. One was a king who hated other people and lived on a planet with no other people on it. Another was a businessman who, because he could count the stars, thought that he owned them. Nothing that these men had to say to the Prince could end the sadness caused by his unhappy love affair.
Now he is on Earth, still in search of answers. In truth, this is where the story ends for the Prince. He dies in the desert. But because of his great warmth, he tells the pilot a story so that the pilot will not feel hopeless. The Prince tells him that although his body is dying, his soul will return to his asteroid.
But although the story is unhappy in this respect, the generous, self-sacrificing Prince himself sets an example to us. We all know that a great, popular book doesn’t have to be a happy one. Generally, the books that win the hearts of readers are neither simply happy nor simply sad. It will both charm you and make you cry, but you won’t quite understand why.

Yesterday I stepped into a restaurant for lunch. As I was waiting my order to come, I noticed the old man in a wheelchair roll himself over to a table. No one and me seemed to notice him. I got up and go over to his table and asked if that I could get him something to drink. He smiled and said,“Thank you. You are generously. I’d like any orange juice, please.”When I was getting ready to leave, I walked by the old man’s table to saying goodbye. He thanked me again and told me I had made his days, coming over and helping him out. I gave him a hug and told him he had made my day, either.
