单选题One of Britain's bravest women told yesterday how she helped to catch suspected (可疑的) police killer David Bieber, and was thanked with flowers by the police. It was also said that she could be in line for a share of up to the ￡30,000 reward money. Vicki Brown, 30, played a very important role in ending the nationwide manhunt. Vicki, who has worked at the Royal Hotel for four years, told of her terrible experience when she had to steal into Bieber's bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building. She said: "I was very nervous. But when I opened the hotel door and saw 20 armed policemen lined up in the car park I was so glad they were there. " The alarm had been raised because Vicki became suspicious (怀疑) of the guest who checked in at 3 pm the day before New Year's Eve with little luggage and wearing sunglasses and a hat pulled down over his face. She said: "He didn't seem to want to talk too much and make any eye contact (接触)." Vicki, the only employee on duty, called her boss Margaret, 64, and husband Stan McKale, 65, who phoned the police at 11 pm. Officers from Northumbria Police called Vicki at the hotel in Dunston, Gateshead, at about 11:30 pm to make sure that this was the wanted man. Then they kept in touch by phoning Vicki every 15 minutes. "It was about ten past two in the morning when the phone went again and a policeman said 'Would you go and make yourself known to the armed officers outside?' My heart missed a beat." Vicki quietly showed eight armed officers through passages and staircases to the top floor room and handed over the key. "I realized that my bedroom window overlooks that part of the hotel, so I went to watch. I could not see into the man's room, but I could see the passage. The police kept shouting at the man to come out with his hands showing. Then suddenly he must have come out because they shouted for him to lie down while he was handcuffed (戴上手铐)./

单选题Tom: Kate, you are back from vacation! How was it? Kate: To tell you the truth, I feel tired. Tom: ______? Kate: I had to visit all my relatives.

单选题Are you planning a vacation? If you like hot and extremely dry summers, go to Phoenix, Arizona. For hot temperatures but lots of rain and thunderstorms, try Miami, Florida. If you want average temperatures and rainfall, St. Louis, Missouri, is the spot. Or if you're a cold weather fan, head to Fairbanks, Alaska. Its winters are very cold with little precipitation. Each of these cities has a certain type of weather. The average weather for a place over many years is called climate, and in no two places in the world is it exactly the same. How can this be? Many things in nature, such as sunshine, temperature, and precipitation, affect climate. Nearness to mountain, oceans, and large lakes affects it too. Another factor is altitude, or height above sea level. Air cools as altitude increases. So a city at a higher altitude may be colder than one at a lower altitude. Finally, winds affect climate. They move heat and moisture between the oceans and continents. Winds keep the tropics from overheating. They keep the polar regions from getting overly cold. Climate changes over long periods of time. Some scientists think, for example, that the earth's climate changed at the time of the dinosaurs. They think the dinosaurs died because of the change. What causes a climate to change? One possible cause may be changes in the sun. Sunspots, for example, are cool, dark spots that form on the sun. Sunspots may decrease precipitation on the earth and cause unusually dry periods. Changes in the atmosphere may change climate too. Volcanic eruptions, for instance, release solid particles into the air. These particles may form a cloud that blocks out the sun's heat. Human activity is another cause of climate change. Air pollution and the reduction of forest cover may have long-term effects on climate.

单选题Several fishermen in Maine recently completed a study program at the country's first ever "Cod(金枪鱼)School." It trains fishermen who usually earn a living fishing in the ocean to be fish farmers. The program is aimed at helping commercial fishers to find a new way to carry out their trade. On a recent morning, a fishing boat left, but the men on the boat were not going fishing, they were going farming. They are going to move the cages and sorting codfish. About one and a half kilometers out to sea, the boat finds eight circular pens. A rubber tube encloses each one. The pens are covered with netting material to keep out seabirds. Inside each of the fifty-meter wide areas are up to fifty thousand cod. Most of these fish will be served on dinner tables around the world. The program will teach the students how to feed the fish and not to over-feed the fish. It means that they should give them enough feed, and not waste any feed and make it as efficient as possible. The fish-farmers in training take turns throwing special fish food into the pen. Air bubbles appear as thousands of cod come up to feed. They can be seen from the boat with an underwater camera. Bill Thompson is one of the Cod School's four students. He says the program has showed him that fish-farming is a wise choice. He said: "Even if the wild stocks came back to their fullest capacity they still wouldn't feed the world. So this is the way of the future. And it's possible for a family to run a business also./
