Article: The use of mobile phones over a long period of time can raise the risk for brain tumors , a new Swedish study said on Friday , contradicting (......) the conclusions of other researchers . The Dutch Health Council , in an overview of research from around the world , last year found no evidence radiation from mobile phones and TV towers was harmful . A four-year British survey released in January showed no link between regular . long-term use of cell phones and the most common type of tumor . However , researchers at the Swedish National Institute for Working Life said they looked at the mobile phone use of 905 people between the age of 20 and 80 who had been diagnosed with a malignant brain tumor and found a link " A total 80 of these 905 cases were so-called high users of mobile phones , that is they began early to use mobile and or wireless telephones and used them a lot , " the study said . " The study also shows that the rise in risk is noticeable for tumors on the sided of the head where the phone was said to be used , " it added . Kjell Mild , who led the study , said the figures meant that heavy users of mobile phones , for instance of who make mobile phone calls for 2 , 000 hours or more in their life , had a 240 percent increased risk for a malignant tumor on the side of the head the phone is used .

And according to town manager Leslie Stanley, it doesn't look as if things will improve any in the immediate future. "We've got a real annoying problem on our hands," he says. The annoyance began in late May. About three miles outside of town a group of beavers built a dam near the mouth of a culvert that carries a stream under Canaan Road. Some 50 feet of roadway and several hundred feet of land on each side of the culvert were flooded. Stanley sent a road crew out to level the dam. The beavers rebuilt it. The crew tore it apart again. In fact, they tore it apart for ten mornings-and for ten straight nights the beavers rebuilt it. On the eleventh day, the foreman tossed the problem back to the town manager. He, in turn, tossed it on to the local game warden . The warden, absorbed in beaver knowledge, moved quietly and carefully out one night and placed a petrol-soaked bag over the dam. (Any beaver expert will tell you the creatures just can't tolerate petrol smell.) In the morning the bag was found artistically woven into the dam. The warden set out three steel traps that night. In the morning one was empty. The other two had been stolen by the beavers and used to strengthen the dam. The warden, cursing the state law against hunting beavers with firearms, got his traps back and set them out again and again. And every night the beavers stole them. Town manager Stanley enlisted additional troops. He telephoned his police chief. Those beavers were breaking a state law against blocking up a natural watercourse. "Why aren't you out there to _ the law?" Stanley asked. "You're the police chief. So remove them. Arrest them. Do something." Three mornings later, the police chief proudly announced the end of the dam. At 2:00 A.M., he said, he and a licensed dynamiter had blown it to small pieces. Stanley said he'd believe it when he saw it. They drove out to the culvert and found a new dam already half-built. They... Question: What can we learn about beavers from the passage? Options: A: The beavers seem to be stubborn about building dams. B: The beavers are allowed to be killed when causing trouble. C: The beavers can't adapt themselves to living in wilderness.

"Things haven't worked out," I said to myself. But, like so many other things I complain before my morning coffee, this one was ridiculously off-key. Things weren't bad; they were good. A hundred yards(91 meters) away was Summit Lake, with its wonderful early morning mists shimmering off the water. A couple of miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet (2,400 meters) above sea level, huge snow banks dotting the place even in mid August. It was beautiful. We fired up the camp stove, got out our cold boxes from the heavy metal locker ,fired up some bacon, cut open some bread, and boiled up a cup of coffee. Half an hour later, my 6-year-old daughter and I were in the parking lot of the Lassen Peak Trail, getting ready to hike. We wouldn't make it all the way-- young legs get pretty tired on a steep mountain path, but it didn't matter. We would see great views spread out below us, the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it. Later, on the hike, I felt stupid about my morning complaints. Everything had been worthwhile. It gave me enormous satisfaction to see my daughter so excited about the view from the mountain. Yes, camping is uncomfortable. But there's also something wonderful about being so close to nature. Just as importantly, there's something about getting young children out of their increasingly technology-filled comfort zones and forcing them to encounter the non-cyber world around them. We lose something when we spend all our time cocooned inside a carefully constructed modernity, when read about daily affronts to the environment, yet don't fully realize what is at risk, removed as we are from nature. It's a good thing to reconnect every so often with the Great Outdoors. By Sasha Abramsky Question: Which of the following is TRUEaccording to the article?
