As I was talking about how I was studying English, the foreigner seemed to be astonished, gently shaking his head ,shrugging his shoulders, saying, "You don't say! You don't say!" I was puzzled, I thought, perhaps this is not a proper topic.Well, I had better change the topic. So I said to him, "Well, shall we talk about the Great Wall? By the way, have you ever been there?" "Certainly, everybody back home will laugh at me if I leave China without seeing it. It was magnificent(,)." He was deep in thought when I began to talk like a tourist guide. "The Great Wall is one of the wonders in the world. We are very proud of it. " Soon I was interrupted again by his order "You don't say!" I couldn't help asking, "Why do you ask me not to talk about it?" "Well, I didn't request you to do so," He answered, greatly surprised. I said, "Didn't you say you don't say?" Hearing this, the Englishman laughed to tears. He began to explain, "You don't say actually means really?

[Q]: Article: prefix = st1 /NEW YORK--So we're going away on weekends and sticking close to home. But are we traveling with the kids? Here's how the down economy is changing the way we travel. SECONDARY CITIES Some smaller cities are stealing the glory . Fort Myers,Fla.experienced double digit growth in January 2009 over January 2008, based on American Express Travel bookings. Cities like Portland,Ore.are also becoming popular destinations, with Travelocity data showing an increase of 38% over last year. EvenPhiladelphia's star is rising, said Travelocity senior editor Shaw Brown. Brown said it's hard to explain exactly the reason for the _ : it could be a decrease in airfare or hotel prices or excellent marketing. Hotel rates inFort Myersare down about 10%. But hotel rates inPortlandare up, she said. She thinksPhiladelphia's higher popularity is due to good marketing, a decrease in airfare of 16% compared to the overall 8% decrease for domestic flights and more interest in historic destinations in general. FAMILY TRAVEL Rather than take a two-week vacation to Europe, families are going to national parks. David Mandt, spokesman for the Association of Amusement Parks, is cautiously optimistic about the summer season. He said even when gas was $4 a gallon in 2008, people continued to visit theme parks--they simply selected parks closer to their homes. While for years, park operators have used special offers, promotions and discounts to encourage families to visit at a specific time, the deals may be easier to find this year, especially when it comes to packages that include accommodations. Universal Orlando Resort has a deal allowing families to book a three-night package and receive two additional nights free. Packages include accommodations at a hotel near Universal and unlimited theme park admission to both Universal Studios and Islands of Adventure.

[Q]: Article: We often use an Internet search engine to find a website that will provide information. For example, if we want to learn something about the Pepsi Cola Company, its website provides information about the history of the company. We can also find articles in newspapers and magazines. We confirm information with second and third sources to make sure the information is correct. Sometimes we also use an encyclopedia --- a set of books containing information on almost any subject. Encyclopedias are written by experts and have been a trust --- worthy source of information for years. Now there is also a free online encyclopedia called Wikipedia, which is written by people around the world. Anyone can edit or add to an article, but this has caused problems. Last year, a former editor of the paper USA Today discovered wrong information about him on Wikipedia. Someone had written an article that falsely linked him to a political assassination . This wrong information was quickly corrected. According to a recent study by the publication Nature, Wikipedia has more mistakes, compared with Britannica --- a well-known printed encyclopedia. It found an average of four mistakes in a Wikipedia article, and three in an article of Britannica's. But Wikipedia supporters note that they are able to correct information when they find a mistake while written publications are not able to do this. Wikipedia started in 2001. The word "wiki" comes from "wiki wiki", which means "quickly" in the Hawaiian language. It is said that it is the largest single source of information in history. It is also one of the fastest growing sites on the Internet. It offers more than three million articles in more than two hundred languages. Each month, it records more than two billion page visits. Jimmy Wales, who helped start Wikipedia, says that its purpose is to provide everyone with a free encyclopedia written in their native language. You can find information on nearly every subject on Wikipedia. However, some experts warn people not to believe everything they read online, no matter where they read it.

Options: (A) can be used for free (B) is written by experts (C) full of mistakes (D) is a set of books
