Nowadays people are troubled by the violence that spreads throughout the media. Movies, television and video games are full of gunplay and bloodshed, and one might reasonably ask what's wrong with a society that presents videos of violence as entertainment. Viewing large amounts of violent television and video games may well contribute to violent behavior in certain individuals. The trouble comes when researchers downplay uncertainties in their studies or overstate the case for causality . Skeptics were dismayed several years ago when a group of societies including the American Medical Association tried to end the debate by issuing a joint statement: "At this time, well over 1,000 studies... point to a causal connection between media violence and aggressive behavior in some children." Freedom-of-speech advocates accused the societies of catering to politicians, and even disputed the number of studies (most were review articles and essays, they said). When Jonathan Freedman, a social psychologist at the University of Toronto, reviewed the literature, he found only 200 or so studies of television-watching and aggression. And when he weeded out "the most doubtful measures of aggression", only 28% supported a connection. The critical point here is causality. The alarmists say they have proved that violent media cause aggression. But the assumptions behind their observations need to be examined. When labeling games as violent or non-violent, should a hero eating a ghost really be counted as a violent event? And when experimenters record the time it takes game players to read "aggressive" or "non-aggressive" words from a list, can we be sure what they are actually measuring? The intention of the new Harvard Center on Media and Child Health to collect and standardize studies of media violence in order to compare their methodologies, assumptions and conclusions is an important step in the right direction. Another appropriate step would be to tone down the criticism until we know more. Several researchers write, speak... What does the writer think of the debate concerning the relationship between the media and violence? A) He more than agrees with the views held by the alarmists. B) It should come to an end since the matter has now been settled. C) The past studies in this field have proved to be misleading. D) More studies should be conducted before conclusions are drawn.

More and more Americans are showing an interest in healthy and locally-produced food. As the interest increases, raising chickens has been gaining popularity in some American cities. "Look, we get three eggs this time." Collecting eggs is a daily pleasure for the Hurst family. Naomi Hurst says her family started to raise chickens in back of their home in Maryland a month ago. "We have wanted to try having backyard chickens for a couple years now. And really just didn't have the time to build my own coop(;) and look out where to buy chickens. And then we met Rent a Coop," said Naomi Hurst. Rent a Coop is a chicken rental business. Tyler Phillips launched the company with a partner 18 months ago. It comes with a mobile coop on wheels, two egg-laying hens, feed, bedding, water bowl, feed bowl, and our 24-hour chicken hotline. You can call with any questions. The price is 185 dollars for four weeks. After the four weeks passed, individuals can extend the rental agreement, return everything or purchase the animals and supplies. Tyler Phillips designs and makes the coops. He says he wants to do as little damage as possible to the environment. "We always try to have as many recycled materials as possible. And I want the coops to be safe for kids. I want the chickens to be comfortable and they have access to the grass while being inside the coop. I want it to be easily movable, light weight," he said. Some cities require people have large pieces of land, if they want to raise farm animals. Others require an agreement with neighbors, limit the number of chickens, or, even ban the birds. Tyler Phillips expects that would change as interest in small poultry coops grows. "I see cities around the D. C. area changing laws almost monthly and different cities will change the law to being prochicken . That is happening all around the United States," he said, He believes that there will be chicken rental businesses in most American cities within five years. We can learn from the passage that _ . A) you can enjoy the Rent a Coop service after 18 months B) you can search online for any questions related to raising chickens C) you can pay for keeping the supplies and the chickens for ever D) you can pay 185 dollars a week for renting things to raise the chickens

Ques: When Omega was born in Uganda, she did two things: Smile and then sing. When Omega was 4 years old, her talent for music was recognized, so she became one of the youngest members of the first African Children's Choir . She traveled the world with the choir, and it was from this experience that she grew into a singer today. Although having a beautiful voice, she had to find other ways besides music to earn a living at first. When she was 16, her parents sent her to the USA to study. Like her mother, Omega wanted to become a doctor and do something meaningful in her country of Uganda. However, like many artists, _ that she had to choose. With encouragement from her family and friends, she opened her own production company after graduation. Since then, she has been working as an artist. Her songs make people feel good about life. Apart from that, she is also interested in health care and education. Omega is one of those Ugandan females who are showing the world their valuable talents. We can learn from the passage that Omega is _ . A) a good teacher B) a famous African artist C) a kind politician D) a warm-hearted doctor
Ans: B
Ques:Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem. In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator. "The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible," he said. Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built. Good initial results were repeated by a larger working model called Vortex installed in a nearby field. "What we have is a mast , which is the top piece and acts as a blade," Yanez said. "It's constructed from the same material as a conventional generator, and what it does is it oscillates , transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind's energy into electric energy." Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and--even more important for many environmentalists--it does not present a threat to passing birds. The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall... What do we know from the passage? A) The original idea was considered as practical in an engineering firm. B) Yanez and Martin's initial tests by themselves proved to be successful. C) The material for constructing the mast is different from that of the past. D) The new generator is better at creating energy than a comparable bladed one.
