2 阅读理解。 As a child, I remember listening to a song called "Wonderful, Wonderful Copenhagen." When I visited the city last year, that song kept running through my head. It got me wondering: Just what is wonderful about Copenhagen? It"s not a place filled with world-famous tourist sites. But it does have a charm(魅力)that makes you want to linger. You can sample the food, visit the castles and museums, and learn about the life of the Danes. Stoget, the world"s longest pedestrian (人行道) mall, runs through the center of the old city. This string of lively street and squares makes walking a treat. I happily explored the mall, looking in the windows of shops and cafes. I followed Stoget from the square in front of the city hall to Nyhavn. Here, old houses painted bright colors look out over a picturesque harbor filled with sailing ships. Denmark"s beloved storyteller Hans Christian Andersen lived here when he wrote his first stories. From Nyhavan, I continued heading north. I wanted to see Copenhagen"s symbol, the statue of the Little Mermaid (美人鱼). She was set up in honor of Hans Christian Andersen"s famous story. As I continued my city tour, one thing impressed me all the bicycles. I learned that half the population of Copenhagen rides bikes every day. Only 20 percent of Copenhageners own cars because there is a 180 percent tax on them. That certainly keeps the city free of traffic jams and heavy pollution! It"s easy to join all the bicyclists pedaling (骑车) through the streets, too. The city provides free bicycles that anyone can use. The cycling around the castles and parks made a relaxing end to a full day. As darkness fell and the parks" lights began to twinkle, I watched families enjoying themselves. So what is wonderful about Copenhagen? Just about everything. 1. What is the purpose of referring to the song in the 1st paragraph? A. To arouse the interest of the readers in the city of Copenhagen. B. To show the readers that Copenhagen is a wonderful city. C. To express the puzzled feeling of the author. D. To ask the readers to find out what is wonderful about Copenhagen. 2. The word "linger" in the 2nd paragraph is most close to______. A. walk B. stay C. learn D. leave 3. The underlined sentence "makes walking a treat" in the 3rd paragraph means _______ . A. You can find various food in this string of lively street and squares B. You will meet many people when walking along the string of lively street and squares C. Walking will be a great pleasure because of the string of lively slmet and squares D. The string of lively strict and squares make people eager to walk along 4. Which of the following is TRUE? A. Copenhagen is a city with lots of places of interest. B. Stoget is the biggest pedestrian mall in the world. C. The government of Copenhagen does encourage people to ride bicycles. D. Nyhavn is a city hall where Hans Christian Anderson once worked.
