China news, Oct. 26--China Great Wall Society's secretary-general Zhang Ji says that the Chinese Academy of Social Sciences (CASS) would join hands with the Society to produce a 3D picture of the Great Wall so that  _ could view its original looks. When the website opens, a picture of the revolving   earth will appear against the background of the universe. A click on the Great Wall will bring the earth nearer, and slowly a white line is seen across the Chinese land in the north. A closer view shows that this is the Great Wall.  Netizens will be able to appreciate the Great Wall with the eye of a tourist and "walk" from Shanhai Pass in the east of the Great Wall to Jiayu Pass in the west in just a couple of days. They can also take a look at the mineral resources and economic status of regions along the Great Wall. CASS and the Great Wall Society are trying their best to make this dream come true through working together closely.  According to Zhang, to achieve the above effects, scientists will rely on airborne   remote sensing, national geographical information system and global positioning system to collect detailed data of the Great Wall, analyze and process the data, apply them to satellite images for 3D translation, and thereafter create a 3D digital image of the Great Wall for the entire world to appreciate the really great Great Wall of China via the Internet. The scientists will rely on the following except  _   to collect detailed data. A) airborne remote sensing B) national geographical information system C) global positioning system D) satellite images

As Artificial Intelligence(AI) becomes increasingly sophisticated, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code. Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language. For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell. Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do. It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules. Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless. The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboo . One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation. If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps , and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else. The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity. What is most difficult to do when we turn human values into a programmable code? A) Determine what is moral and ethical. B) Design some large-scale experiments. C) Set rules for man-machine interaction. D) Develop a more sophisticated program.

Everyone has good days and bad days. Sometimes, you feel as if you're on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork. For more than 20 years, scientists have suggested that high self-esteem   is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. "Forget about self-esteem," says Jennifer Crocker, a psychologist   at the University of Michigan, US. "It's not the important thing." Feeling good Crocker's advice may sound a bit strange because it is good to feel good about yourself. Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and wicked people often have the highest self-esteem of all. He also said: "There's no evidence that kids with high self-esteem do better in school." Problems All types of people have problems. People with high self-esteem can have big egos   that can make them less likeable to their peers , said Kathleen Vohs, a psychology professor at Columbia University. People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. What to do Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something try to learn from the experience. "The best therapy   is to recognize your faults," Vohs says. "It's OK to say, 'I'm not so good at that,' and then move on." The new research comes to the conclusion that high self-esteem   _  . A) is not important at all B) has taken on a different meaning C) may not be the key to success D) does not help you do better at school
