"Terrible," said Greg Dudzinski,17,of Ripon High School in Wisconsin,as he toured the US capital. "The regular hamburgers are bad enough,so soyaburgers would be a lot worse," offered Zach Richey,13,of Scottsboro Junior High in Alabama,another tourist. But the United States government--hoping to reduce the amount of fat that children are eating--has approved the use of soy as a meat substitute in meals for schools and day-care centers. Not all kids dislike the change Mariel Spano,17,of Sandy Creek High School in New York,also visiting the capital,said she likes soyaburgers:"There's less fat,and they're better for you.They taste the same,and they're just as good." The government tried to make soy a meat substitute nearly 20 years ago-but later dropped the idea.At the time,the plan was intended as a cost-cutting move .US Agriculture Department officials say their purpose now is only to make meals healthier. Schools are likely to increase the amount of soy that is mixed with hamburgers and other foods already on their menus,and they will also be looking to food companies to develop new soy products that children will like "I can't see putting tofu on a student's plate as being acceptable.I can see taking a product that's familiar to the students and adding a large amount of soy to it and having it be acceptable," said Jill Benza,director of food services for the Mesa,Arizona schools. Question: What is the newspaper report mainly about? Options: A: The difficulty in using soy products for US schools. B: Various opinions on soy products for US schools. C: The plan that is made by the US government for school lunch. D: Healthy foods for students in US schools.

Read the article and select the best answer. Article: What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many... Question: According to Theory Second, the disaster happened to the Titanic mainly because _ . Options: A: the freezing weather made the watcher not be able to watch clear B: the mirage on the sea attracted the watcher and made him forget his work C: the high tides drove the icebergs float so fast that the watcher didn't respond to them D: the mirage made the watcher not find icebergs and a nearby ship delay rescuing

Read the article and select the best answer. Article: Several years ago, a student working on a research project in my laboratory approached me with concern."I'm doing something wrong,"she exclaimed. I had seen her research results and knew she was making good progress, so I was surprised to hear that she was having a problem. Over the next several days we went through her experiment; yet I could not find a problem. Finally, I asked her,"Why do you think you're doing something wrong?" "Because I'm not getting what you said I should get,"she replied with some confusion. Her response shocked me. I had not told her what she"should get", but we had discussed some published hypotheses several weeks earlier. On seeing the research data that did not fit these predictions, I recognized that she had a new finding and came to change my hypotheses. But she was interpreting her results as a mistake. With almost four years of a college science major behind her, this student still had the common misunderstanding that science is a boring exercise in proving something we already know to be true. But how can this happen? Throughout school, science is often described in textbooks as a series of"known"facts and figures; for example, DNA is a double helix; earthquakes occur at plate boundaries, etc. Unfortunately, the process by which these discoveries were made and how they fit into scientific progress are often ignored in the classroom. These details help show the nature of scientific discoveries and the tails help show the nature of scientific discoveries and the skepticism that goes with new discoveries before they are accepted. Understanding science is more than memorizing that DNA is a double helix. It is to have the ability to take in new information on diet, exercise, or disease and apply it to our own lives. Understanding the process of science and scientific problem-solving can help us make better decisions every day. Question: What is to blame for the student's misunderstanding about science? Options: A: Her own carelessness. B: Her teacher's lack of experience. C: The method of science education. D: The publication of some wrong hypotheses.
