Article: One of my China Dialogue colleagues in Beijing recently bought a Philips energy-saving light bulb to replace a standard one.He was happy with his choice.It may have cost 30 yuan (just under US$4.50) - ten times the price of a filament bulb - but he wanted to save energy as part of his low-carbon lifestyle.And according to the shopkeeper, he would save, in the long run, much more than the 30 yuan he was spending. Yet only one month later, his expensive light bulb blew up, before he had saved even a small part of the purchase price.Will he stick to his high-cost, low-carbon lifestyle? China's environmental organizations have started to advocate low-carbon lifestyles and the decrease of carbon footprints to help fight against climate change.But they have overlooked one fact: in China, low-carbon living comes at a high cost.It means buying energy-saving bulbs and appliances, and environmentally friendly building materials and daily goods.Cost can no longer be the only standard for purchases.An energy-saving and environmentally friendly product is more expensive than a standard alternative - whether it's a simple light bulb or the house it shines.For average consumers, even buying an ordinary bulb is a huge burden.How can we persuade ordinary people to choose an energy-saving residence? This is not a trend they can afford to follow; perhaps this fashion is only for the rich. Most consumers today do not cause huge carbon dioxide (CO2) emissions.Their responsibility lies not in choosing a low-carbon lifestyle today, but in avoiding a high-carbon life in the future.The principle of "common but differentiated responsibility" - a basis of sustainable development - can be applied here as well. In China, low-carbon living still is resisted by a lack of social infrastructure . Even if your salary allows you to make that choice, nobody is there to help you accomplish it. Consider energy-saving homes. You need to find out whether or not the developer has used natural materials wherever possible; how effective the... Question: We can infer from the passage that _ . Yes or no, is the answer "All citizens in China don't have the same responsibility in living a low-carbon lifestyle."?
No

Article: Have you ever had a doctor write you a prescription for three laps around a local trail ? How about a prescription for sit-ups? These treatments may not be as typical as the drugs that are usually used to treat our problems, but maybe they should be: a new report shows that regular exercise can be just as effective as prescription drugs for patients with depression and anxiety. "Individuals who exercise report fewer symptoms of anxiety and depression, and lower levels of stress and anger, " said the paper's co-author, Jasper Smith, director of the Anxiety Research and Treatment Program at Southern Methodist University. " Exercise may help patients with depression re-establish positive behaviors. For patients with anxiety disorders, exercise reduces their fears of fear and related bodily sensations such as a racing heart and rapid breathing." In a separate study, published in Physical Therapy journal, scientists studied 161 women who' d recently given birth to babies, and decided them into two groups. New mothers tend to develop post-partum depression , and the scientists wanted to find out whether exercise could prevent such problems. One group of women was given specialized exercises as part of an eight-week parenting education program, while the other was given only written education. The physical element seemed to do the trick; the researchers report that the number of women identified as "at risk" for post-partum depression was reduced by half in the exercising group. Another recent study shows that even when a patient has a chronic illness like cancer or a heart condition, regular exercise can dramatically increase wellbeing by reducing anxiety. Researchers from University of Georgia analyzed 40 clinical trials involving almost 3,000 patients, and found that the patients who reported exercising regularly had a 20% reduction in symptoms of anxiety compared to those who didn't exercise. As a result, they were more likely to follow their recommended treatment plan. Of course, there are still some... Question: What is the text mainly about? Yes or no, is the answer "Regular exercise can reduce the symptoms of depression and anxiety."?

Ques: Article: People in Shanghai can quench their thirst with high quality water if the Shanghai Water Authority (SWA) is able to make good on its word. It has vowed to make the city's water match its status as a world class city. "The current tap water quality meets national standards, but, compared with that of the European Union and the United States, it still needs to be improved." said the SWA's director general, Hang Jiayi. In other developed countries, water fountains can be found almost everywhere--people do not bother with bottled drinking water. By 2020, the water of the Huangpu River will be treated to reduce the amount of organic waste in it. Major water works that draw water from the Huangpu will need more treatment facilities to improve the colour, texture, ammonia and nitrogen content before 2010. These treatment facilities are expected to cost 4 billion yuan, something that could affect the price of water, according to Chen Yin, SWA's deputy director general. Chen said that replacing water pipes was also a key project. The city's aged pipes are mostly to blame for the bad water quality. The SWA has started the water facilities renovation work, including the more than 14,000 kilometres of indoor piping, 107,000 tanks on top of the buildings, and more than 6,000 underground facilities. World Water Day came on March 22, and this year's theme is "Water for the future". Beijing is also drawing up plans during China's Water Week, which runs until March 28. By 2010, the water for the Shanghai EXPO is to be above World Health Organization standards. And, the people of Beijing will be able to drink their tap water as well. Question: What step need not be taken in order to improve the tap water? Yes or no, is the answer "Water fountains must be found."?
Ans: Yes

Article: Boris Worm of Dalhousie University in Nova Scotia ,prefix = st1 /Canada, led the international team that did the study . Professor Worm says species have recently been disappearing from oceans at increasing speed . At this rate , he says , all seafood species could collapse could collapse by 2048 . Other studies have also warned about the dangers of overfishing and the effects on ocean environments . But not everyone thinks the oceans are likely to be empty in fifty tears . Some scientists said parts of the world do have problems , but others are doing a good job of protecting fish populations . Government officals in several countries with large fishing industries also questioned the research . The study appeared earlier this month in Science magazine . The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems . These complex systems help control water quality . The scientists say the loss of different kinds of sea life appeared to increase the f fish kills and beach closures from harmful algae growth . The scientist examined the results of thirty-two experiments and observed forty-eight protected areas . They also looked at records of catches worldwide . They studied records from the United Nations Food and Agriculture Organization from nineteen fifty to two thousand three . And they examined archeological information and other historical records for twelve coastal areas . That research back over a thousand years . Boris Worm says the findings were , in his words , " beyond anything we suspected . " But he also said the situation is not too late to correct . He said that with good fisheries management , some species could completely recover in three to ten years . Question: Which statement of the following is NOT TRUE about the research led by Boris Worm ? Yes or no, is the answer "It lasted from 1950 to 2003"?
Yes
