It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野). For Killing Wolves In Alaska, the wolves almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, laws were established to protect the wolves from sportsmen and people who catch the animals for their fur. So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life. When the deer can"t find enough food, they die. If the wolves continue to kill large numbers of deer, their prey(猎物)will disappear some day. And the wolves will,too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We"d also save some farm animals. In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population. Against Killing Wolves If you had lived long ago, you would have heard many different stories about the dangerous wolf. According to most stories, hungry wolves often kill people for food. Even today, the stories of the "big bad wolf" will not disappear. But the fact is wolves are afraid of people. and they seldom travel in areas where there is a human smell. When wolves eat other animals, they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature. Although some people say it is good sense to kill wolves, we say it is nonsense! Researchers have found wolves and their prey living in balance. The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life. The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs. The wolves can"t always find enough food. So they travel to the nearest source, which is often a farm.Then there is danger. The "big bad wolf" has arrived! And everyone knows what happens next. |

Safety in thehighway is not totally out of hands. Here are four ways we canprotect ourselves when we travel. You are safer in a large car. People in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products" safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem. Being thrown into glass and metal car parts, or being thrown from the car, can really damage to you. That"s why safety belts should be worn. The safety belt"s main purpose is if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of fatal injury by 45% and the chance of serious injury by 50%. Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal ( 正面的) crashes-the type of crash that kills the most drivers- when they are also wearing safety belts. Most people are demanding air bags in the cars they buy. But the protection provided by air bags is limited in side or rear crashes; effective as they are, they can"t take the place of safety belts. Drunk driving crashes are less likely to happen if you don"t drink. Drunk driving is the most serious problem. Many people have realized that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties ( 处罚) for drinking and driving. |

[1]Losing weight is hard enough. Keeping it off is even harder. Now a new study by researchers at Penn State suggests that the techniques that work for losing weight aren"t necessarily the same as those that help keep you slim. [2]First the researchers surveyed over 1,100 people who had achieved significant weight loss and maintained ( 维持) it. The researchers identified 36 weight-loss and weight- maintenance practices that at least 10% of the group used. [3]Then the researchers conducted a national telephone survey of overweight people who had tried to lose weight and keep it off with varying success: about 11% reported successfully losing weight, and 21% were able to maintain that loss for at least a year. [4] The survey found people who ____ did so by participating in weight loss programs, cutting back on sugar, eating healthy snacks, not skipping meals and participating in different types of exercise. [5]Still,say many nutrition and obesity experts. The basic principles of weight loss and maintenance are the same; you have to eat a healthy diet and increase your exercise. People who lose weight and keep it off tend to eat significantly healthier foods and do a lot more exercise than the average American. [6] But what may maintain between weight-loss and maintenance is a person"s attitude; rather than focusing on actively losing weight in the short term. People have to start focusing on long-term, permanent lifestyle changes and behaviors, if they want to maintain the weight that"s been lost. The key to success, experts agree, is motivation, not necessarily the particulars of your weight-loss program.

Solar electric systems pay off most quickly for consumers who use a lot of energy because extra charges are given for heavy use, but the solar system still makes sense for low-energy users such as myself. So much of Americans" carbon footprint results from buildings-about 43%, according to the U.S. Department of Energy. I"m in a household of 1.5 (mom and 7-year-old), and we use only about 4 kilowatt hours of electricity per day, something we"ve managed through behavioral changes, such as turning off the lights in rooms after we"ve exited, and through in-home efficiencies (效率), such as swapping out all my light bulbs for energy-saving ones and using power boards that can turn off DVD players, coffee makers and other electrical equipment. Using less electricity means I can get by with a smaller, less expensive solar system that not only covers my use but also produces a credit on my power bill. Going solar also meant my house was upgraded with a time-of-use meter. This type of meter allows me to receive credit for the electricity I produce during peak hours when electricity costs the most, but pay the least for the electricity during off-peak hours, when I recharge my cell phone and laptop and perform other tasks requiring power. The downsides are that I am tied in to the grid (电网) and still affected by power failure, and I now have solar panels (太阳能电池板) that need to be cleaned. It"s a subject of debate, but REC Solar said dirty panels decrease energy production by 6% to 8%.Many panel producers recommend cleaning panels at least once during the summer. I wash mine whenever they look dirty or dotted with bird droppings, which is about every other week. I think $6,000 is a small price to pay, not only for panels that should produce my next 20 years of electricity, but also for the greenhouse gases I"m not creating. |
1.What is mainly talked about in this article? |
A. The ways of cutting power bills. B. The tips on reducing electricity use. C. The benefits of using solar systems. D. The importance of protecting the environment. |
2.Why does the writer recharge her mobile phones during off-peak hours? |
A. To save credit. B. To save time. C. To save energy. D. To save money. |
3.The underlined word "downside" in Paragraph 4 is close in meaning to ______. |
A. discount B. disadvantage C. disapproval D. disagreement |
4.The author cleaned her power panels ______. |
A. to make them work properly B. to protect the environment C. to make them look better D. to avoid power failure |

You might think that "global warming" means nothing more than a rise in the world"s temperature. But rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation-the citizens of Tuvalu will have to leave their homeland. During the 20th century, sea level rose 8-12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the country"s drinking water. Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms. Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international. agreement calling for industrialized nations to reduce their greenhouse gas emissions (导 致温室效应的气体排放 ) , which are a main cause of global warming. "By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years," Laupepa told the BBC. Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries . Tuvalu is not the only country that is vulnerable(易受影 响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an "endangered nation". |

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States. The result:10% fewer heart attacks.8% fewer storkes.4% fewer deaths.11% fewer new cases of heart disease. And 240 billion dollars in health care savings. Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year. The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University. Each gram of salt contains four hundred milligrams of sodium(钠),which is how foods may list their salt content. The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure. New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference. Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children"s Research Institute shows that the calorie information on the menu can influence what parents order for their children. |
