Article: Hong Kong is one of the most densely populated cities in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation for its light pollution. A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard. The crowded city of 7 million residents , full or residential high-rises, towering office blocks and neon advertisements, has no laws to control outdoor lightning. The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai. "In Hong Kong , you can't go anywhere outdoor in the evening without your eyes being blinded by this really disturbing outdoor lightning," the light pollution survey's head Jason Pum told AFP. "The fact that we have all this light in the sky means energy is wasted," he said, adding that too much artificial lightning also affects nightly wildlife. Research has suggested that light pollution can cause a number of harmful health effects in humans, including sleeplessness and headaches and can also interrupt body clocks and hormones . The university survey, the result of five million measurements taken from points across the city, was released just days before the start of the annual Earth Hour event, organized by the World Wildlife Fund. People around the world will be encouraged to turn off the lights for an hour on Saturday night to raise awareness of climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour. "Anyway, we should do our best to reduce the amount of lightning and adjust it for the benefit of the environment." Question: .which of the following statements about too much lightning is NOT true? Yes or no, is the answer "It can make the sky and the city more beautiful."?

Article: Very old people do raise moral problems for almost everyone who comes in contact with them. Their values--this can't be repeated too often--are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms , and an old person lying alone in bed, taking no notice of the worms. But is it interfering with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old. Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you stop treating the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there's life, there's hope. When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun. Question: Some social workers think that _ . Yes or no, is the answer "health and safety are more important than personal freedom"?

Article: Old people are easy to feel lonely because their children are busy with their work and have little time to spend with them.Most of them have to be companied by pet dogs.However,it is sometimes impossible for some old people to keep pet dogs because they are too old or ill to take care of pet dogs. Experts are studying the influence of robotic dogs on old people's depression ,physical activity,and life satisfaction.Researchers are placing robotic dogs in the homes of lonely old people to see whether they can improve the quality of life for old people.Alan Beck,an expert in human-animal relationship,said,"Old people should be more active,challenged,excited.The problem is how we promote that,especially for those without friends or help.A robotic dog could be a solution." In the study,the robot,called AIBO,is placed for six weeks in the houses of some old people who live alone.These old people will keep a diary to note their feelings and activities before and after AIBO.Researchers will collect basic data for six weeks.Then,the researchers will review the data to decide if there are any changes in the life of its owner. "I talk to him all the time,and he responds to my voice,"says a 70-year-old lady."When I'm watching TV,he'll stay in my arms until he wants down.He has a mind of his own." The AIBOs respond to certain orders.The researchers say they have some advantages over real dogs,especially for old people.Often the elderly are disabled and cannot care for an animal by walking it or playing with it.A robotic dog needn't any exercise and feeding concerns. "At the beginning,it was believed that no one would prefer the robotic dog because it was metal and not furry ,"Beck says."But it's amazing how quickly we have given up that belief." Hopefully,these robotic pets could become a more valuable health helper.They will record their masters'blood pressure,oxygen levels,or heart rhythms.AIBOs may even one day have games that can help exciting older people's minds. Question: From the passage we can learn that old people can easily feel lonely because . Yes or no, is the answer "their children are too busy to stay with them"?
