单选题{{B}}Text 3{{/B}} Americans today have different eating habits than in the past. There is a wide selection of food available. They have a broader knowledge of nutrition, so they buy more fresh fruit and vegetables than ever before. At the same time, Americans purchase increasing quantities of sweets, snacks and sodas. Statistics show that the way people live determines the way they eat. American life styles have changed. They now include growing numbers of people who live alone, single parents and children, and double income families. These changing life styles are responsible for the increasing number of people who must rush meals or sometimes skip them altogether. Many Americans have less time than ever before to spend, and almost all American homes now have microwave ovens. Moreover, Americans eat out nearly four times a week on the average. It is easy to study the amounts and kinds of food that people consume. The United States Department of Agriculture (USDA) and the food industry growers, processors, marketers and restaurateurs compile sales statistics and keep accurate records. This information not only tells us about what people are eating, but in, fluences them on what to eat. Red meat, which used to be the most popular choice for dinner, is no longer an American favorite. Instead, chickens, turkey, and fish have become more popular. Sales of these foods have greatly increased in recent years. This is probably a result of the awareness of the dangers of eating food which contains high levels of cholesterol, or animal fat. Doctors believe that cholesterol is a threat to human health. According to a recent survey, Americans also change their eating patterns to meet the needs of different situations. They have certain ideas about which foods will increase their athletic ability, help them lose weight, make them alert for business meetings, or put them in the vegetables, which supply them with carbon hydrates, to give them strength for physical activity, such as sports. Adults choose foods rich in fiber, such as bread and cereal for breakfast, and salads for lunch to prepare them for business appointments. For romantic dinners, however, Americans choose shrimp and lobster. While many of these ideas are based on nutritional facts, some are not. Americans' awareness of nutrition, along with their changing tastes and needs, leads them to consume a wide variety of foods — foods for health, for fun, and simply for good taste.

单选题NASA, the U.S.space agency, believes there's a good chance that we're not alone in the universe. Last fall, NASA began a new project called the High Resolution Microwave Survey (HRMS). Its aim: to find evidence of life in one of the billions of galaxies in the universe. The search for intelligent life on other planets isn't new. It began almost 100 years ago. That's when scientists built a huge transmitter to beam radio waves into space. Scientists thought smart beings on other planets might pick up the signals. Scientists also have beamed a message about humans and our solar system to a nearby constellation. But because the constellation is 25,000 light years away, a return message wouldn't reach Earth for 50,000 years! So don't wait up for an answer. So far, no Ets ( Extraterrestrial beings ) that we know of have returned our "calls." But according to Dr. Jill Tarter, an HRMS scientist, we haven't exactly had our ears wide open. "Now, however," says Dr. Tarter, "we've built the tools we need to listen well." Last October, Dr. Tarter switched on the largest radio receiver in the world. It's an enormous metal bowl stretching 1,000 feet across a canyon in the jungles of Puerto Rico. Meanwhile, another NASA scientist flipped on a huge radio antenna in California's Mojave Desert. NASA hopes these big dishes—and others around the world—will pick up radio signals from new world. Dr. Frank Drake had been searching for life in outer space for years. He explains the HRMS project this way: To listen to your radio, you move the tuner on the dial until the channels come in loud and clear. Now imagine radio receivers that scan our galaxy "listening" to 14 million channels every second. That's what NASA's radio telescopes in Puerto Rico and California are doing. But that's not all. Powerful computers hooked to the telescopes sift through every signal. The computers try to match the signals to ones that scientists already recognize, such as human-made signals. If they can't, Drake and Tarter check on them. "It could prove there is radio technology elsewhere in the universe," says Dr. Tarter. "And that would mean we're not alone./
