The storms were dramatic and dangerous. George Snyder was driving the fire truck down Route 88 when he first noticed that a funnel (漏斗状的) cloud was behind him. "I stopped the truck and watched the funnel cloud. It was about 100 feet off the ground and I saw it go up and down for a while. It was moving toward Bradley Road and then suddenly it disappeared," Snyder said. Snyder only saw one of the funnel clouds that passed through northeastern Ohio on Saturday. In Trumbull County, a tornado turned trees onto their sides. Some trees fell onto houses and cars. Other trees fell into telephone and electrical wires as they went down. Amanda Symcheck was having a party when the storm began. "I knew something was wrong," she said." I saw the sky go green and pink (粉红色). Then it sounded like a train rushing toward the house. I started crying and told everyone to go to the basement for protection." The tornado caused a lot of damage to cars and houses in the area. It will take a long time and much money to repair everything. There was also serious water damage from the thunderstorms. The heavy rains and high wind caused the power to go out in many homes. The storms caused serious flooding in areas near the river. More than four inches of rain fell in parts of Trumbull County. The river was. so high that the water ran into streets and houses. Many streets had to be closed to cars and trucks because of the high water. This made it difficult for fire trucks, police cars, and other rescue vehicles to help people who were in trouble. Many people who live near the river had to leave their homes for their own safety. Some people reported five feet of water in their homes. Local and state officials opened emergency shelters for the people who were evacuated (撤走). The Red Cross served meals to them. "This was a really intense storm," said Snyder. "People were afraid. Mother Nature can be fierce. We were lucky this time. No one was killed."

Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area--and they can be devastating．In 1906，for example，a major quake destroyed about 28,000 buildings and killed hundreds，perhaps thousands of people．Residents now wonder when the next“Big One”will strike．It's bound to happen someday．At least seven active fault(断层)lines run through the San Francisco area． Faults are places where pieces of Earth's crust(地壳)slide past each other．When these pieces slip，the ground shakes． To prepare for that day，scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens． One new finding about the 1906 quake is that the San Andreas fault split apart faster than scientists had assumed at the time．During small earthquakes，faults rupture(断裂)at about 2.7 kilometers per second．During bigger quakes，however．ruptures can happen at rates faster than 3.5 kilometers per second． At such high speeds，massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself．Lucky for San Francisco，these pressure pulses(脉冲)traveled away from the city during the 1906 event．As bad as the damage was，it could have been far worse． Looking ahead．scientists are trying to predict when the next major quake will occur．Records show that earthquakes were common before 1906．Since then，the area has been relatively quiet．Patterns in the data，however，suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent． New buildings in San Francisco are quite safe in case of future quakes．Still，more than 84 percent of the city's buildings are old and weak．Analyses suggest that another massive earthquake would cause extensive damage． People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while．According to the new research，however．it's not a matter of“if”the Big One will hit．It's just a matter of when．

单选题New Material, New Fashion The January fashion show, called FutureFashion, exemplified (例证) how far green design has come. Organized by the New York-based non-profit Earth Pledge, the show inspired many top designers to work with sustainable fabrics (纤维) for the first time. Several have since made pledges to include organic fabrics in their lines. The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to find. "Most designers with existing labels are finding there aren't comparable fabrics that can just replace what you're doing and what your customers are used to," he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents. Those who do make the switch are finding they have more support. Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs (企业家) who attend its two springtime shows in Los Angeles and New York and gave special recognition to designers whose collections are at least 25% sustainable. It now counts more than 50 green designers, up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative aimed at helping cotton farmers go organic: it will buy transitional (过渡型的) cotton at higher prices, thus helping to expand the supply of a key sustainable material. "Mainstream is about to occur," says Hahn. Some analysts (分析师) are less sure. Among consumers, only 18% are even aware that ecofashion exists, up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted consumer. When asked if she owned any sustainable clothes, she replied: "Not that I'm aware of." Like most consumers, she finds little time to shop, and when she does, she's on the hunt for "cute stuff that isn't too expensive." By her own admission, green just isn't yet on her mind. But—thanks to the combined efforts of designers, retailers and suppliers—one day it will be.

Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights, nearly a third felt they were overweight and were trying to lose pounds. Even at the tender ages of 10, nearly 32 per cent of girls felt "too fat" and 31 per cent said they were trying to diet. McVey, a researcher at the Hospital for Sick Children in Toronto, and her colleagues analyzed dam collected in a number of surveys of southern Ontario school girls between 1993 and 2003, reporting their findings in Tuesday's issue of the Canadian Medical Association Journal. Nearly 80 per cent of the girls had a healthy body weight and only 7.2 per cent were considered overweight using standard weight-to height ratios. Most researchers suggest the rate of overweight children in this country is several times higher than that figure. Nearly 30 per cent of the girls reported they Were currently trying to lose weight, though few admitted to dangerous behavior such as self-induced vomiting. Still, a test that measured attitudes towards eating showed 10.5 per cent of survey Participantswere already at risk of developing an eating disorder. "We're not talking about kids who've been prescribed a diet because they're above average weight or overweight. We're talking about children who are within a healthy weight range. And they have taken it upon themselves to diet to lose weight," McVey said, acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task, with no easy solutions. overweight adj. 超重的，过重的 induce vt.引起，导致 prescribe vt.处方;开药;嘱咐

单选题Earth Rocks on Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates)slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4.5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust (地壳), eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is 1.3 billion years earlier than previous ones. Not long before 3. 8 billion years ago, lots of asteroids (小行星) were hitting Earth, keeping its crust in a hot, melted state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地壳) belt. The rocky crust there is between 3.7 and 3.8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock, called magma (岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beginning around 3.8 billion years ago.

Furthermore, during the summer there are few clouds in the sky to protect plans from the sun' s ray. Another problem is the fact that there are frequently strong winds that drive small, sharp particles of sand into the plants,earing and damaging them. The most difficult probiem for all forms of plant life, however, is the fact that the entire annual rainfall occurs during a few days or weeks in spring. Grasses and flowers in desert survive from one year to the next by existing through the long, hot, dry season in the form of seeds. These seeds remain inactive unless the fight amount of'rain falls. If no rain falls, or if insufficient rain falls, they wait until the next year, or even still the next. Another factor that helps these plants to survive is the fact that their life cycles are short. By the time the water from the spring rains disappears — just a few weeks after it falls — such plants no longer need any. The perennials (多年生植物) have special features that enable them to survive as plants for several years. Thus, nearly all desert perennials have extensive root systems below ground and a small shoot system above ground. The large root network enables the plant to absorb as much water as possible in short time. The small shoot system, on the other hand, considerably limits water loss by evaporation. Another feature of many perennials is that after the rainy season they 10se their leaves in preparation for the long, dry season, just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation (蒸发) duing the dry season. Then, in next rainy season, they come fully alive once more, and grow new branches, leaves and flowers, just as the grasses and flowers in desert do.

单选题 下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} How to Educate Children{{/B}} As Eleanor Roosevelt once said, “Universal human rights begin in small places, close to home.” And Tolerance, org, a Web site from the Southern Poverty Law Center, is helping parents across the country create homes in which tolerance and understanding are guiding themes. “The goal of nurturing open-minded, empathetic children is a challenging one,” says Jennifer Holladay, director of Tolerance; org. “To cultivate tolerance, parents have to instill in children a sense of empathy, respect and responsibility—to oneself and to others—as well as the recognition that every person on earth is a treasure.” Holladay offers several ways parents can promote tolerance: Talk about tolerance. Tolerance education is an ongoing process; it cannot be captured in a single moment. Establish a high comfort level for open dialogue about social issues. Let children know that no subject is taboo. Identify intolerance when children are exposed to it. Point out stereotypes and cultural misinformation depicted in movies, TV shows, computer games and other media. Challenge bias when it comes from friends and family members. Do not let the moment pass. Begin with a qualified statement: “Andrew just called people of XYZ faith ‘lunatics.’ What do you think about that, Zoe?” Let children do most of the talking. Challenge intolerance when it comes from your children. When a child says or does something that reflects biases or embraces stereotypes, confront the child: “What makes that joke funny, Jerome?” Guide the conversation toward internalization of empathy and respect—“Mimi uses a walker, honey. How do you think she would feel about that joke?” or “How did you feel when Robbie made fun of your glasses last Week?” Support your children when they are the victims of intolerance. Respect children’s troubles by acknowledging when they become targets of bias. Don’t minimize the experience. Provide emotional support and then brainstorm constructive responses. For example, develop a set of comebacks to use when children are the victims of name-calling. Create opportunities for children to interact with people who are different from them. Look critically at how a child defines “normal.” Expand the definition. Visit playgrounds where a variety of children are present—people of different races, socioeconomic backgrounds, family structures, etc. Encourage a child to spend time with elders—grandparents, for example. Encourage children to call upon community resources. A child who is concerned about world hunger can volunteer at a local soup kitchen or homeless shelter. The earlier children interact with the community, the better. This will help convey the lesson that we are not islands unto ourselves. Model the behavior you would like to see. As a parent and as your child’s primary role model, be consistent in how you treat others. Remember, you may say, “Do as I say, not as I do,” but actions really do speak louder than words.
