Ques:Article: 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... Question: What is the skeptics' view of media violence? Yes or no, is the answer "Most studies exaggerate   the effect of media violence on the viewers."?

Ques:Article: In the 1960s Walt Disney pictured in the mind a future utopian city with underground roads and a climate-controlled round roof. The real community of Celebration, Florida, built in 1999, applies the social and environmental goals of both Disney and the New Urbanism movement. Disney and the New Urbanism have imagined communities that promote social and local communication. Celebration has a central Market Street district to reduce traffic and encourage social contacts. The idea is that if the downtown area is neatly and closely ranked, people will walk and meet their neighbors. Downtown events like arts festivals also bring citizens together. Narrow, tree-lined streets are "traffic calm"----with slower speed limits----to encourage bicycling and walking.    Moreover, housing in Celebration includes both single- and multi-family houses that encourages socialization. Apartment buildings are located close to downtown, and houses are built close together with small yards. They feature entrance halls to encourage citizens to socialize.    "Many aspects of that kind of design are really aimed at maximizing social communication between citizens, not just on the streets but also in community institutions that are very much a part of public life there," says Andrew Ross, a New York University professor who lived in Celebration for one year.    Utopian communities such as Celebration are also designed with environmental protection in mind. The town itself is built on 4,900 acres surrounded by a 4,700 acre protected greenbelt. The greenbelt parks, and common areas accommodate native wildlife and animals.    High-rise office and apartment buildings provide close office and living space in a small geographic area in order to reduce urban  _ , the spread of today's cities onto nature areas. Buildings also minimize environmental influence by using cooling; and electric systems with insulated (;) glass, cooling towers, and energy-saving lamps.    "The town more or less borrows very heavily from New Urbanist principles...to... Question: Celebration mentioned in the passage is a   _   . Yes or no, is the answer "community promoting socialization"?

Ques:Article: Looking back on China's road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China's first satellite into the Earth's orbit in 1970 came four flights of unmanned Shenzhou missions  from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China's second human spaceflight, was launched, with a crew of two astronauts. What's more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration. Meanwhile, China's moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world's first man-made satellite, China's first circumlunar satellite Chang'e 1 took off on Oct.24, 2007, which became another milestone  in China's space achievements after the above-mentioned manned flights. Chang'e 1 was expected to fulfill four scientific goals, one of which was to probe mineral elements on the moon, especially those not existent on Earth. It's said that the lunar regolith  is abundant in helium-3, a clean fuel that may support the Earth's energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang'e 2, China's 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang'e 3 and Chang'e 4, as a preparation for a soft lunar landing in the future. With great expectations, people all over the world are looking forward to China's greater space achievements. Question: We can infer from the text that   _  . Yes or no, is the answer "China's scientists are researching into techniques for soft lunar landing"?

Ans:Yes

Ques:Article: In some countries,open campus   is widely accepted. For example, French students have a two-hour lunch break from 11:30 a.m. to 1:30 p.m. During their lunch break, they can eat at home or at a restaurant. But students in the Philippines have a tougher schedule. They have only two 15-minute breaks and an hour for lunch. What Schedule would be best for American schools? Having breaks between classes is great, but having breaks off campus is even better. There are several advantages to open campus, including simple conveniences such as being able to eat different meals during lunchtime, rather than having the cafeteria   dishes, as well as having the chance to take a break at home. However, there are more reasons I disagree with allowing high school students the right to have an open campus. Sure, it's great being able to escape school during the day for a while, but soon enough that may easily become the rest of the day. If open campus is allowed, it is very possible that such freedom will make it all too easy for students to skip their afternoon classes. Of course, there will be students responsible enough to come back to school. But unexpected problems such as heavy traffic, city bus delays   or cars breaking down may prevent them from returning to school. It benefits the students to stay in school during lunch hours to avoid transportation issues. Depending on how close the school is to restaurants and students' homes, open campus could be a great idea. Unfortunately, though, most public schools in America are not located close enough to restaurants or students' homes, thus causing the negative results to outweigh   the positives in the end. Question: What can we learn from the text about most American public schools? Yes or no, is the answer "They are far from students' homes."?
