However, scientists who study the brain have learned many interesting things from studying the brains of daydreamers. Far from being a waste of time, recent research has shown that daydreaming is a healthy and useful activity for all of our brains. To study the brain, scientists use special devices that scan the brain and show pictures of which parts of the brain are active at certain times. When a person is daydreaming, the device will show a distinct pattern of activity in the brain called the "default" mode of thinking. In the default mode, the top or outside part of the brain is very active. Actually, several regions of the brain are interacting in this mode. Some scientists describe this mode as a time when the brain focuses on itself rather than focusing on the environment around the person. Typically, this occurs when a person is doing simple, undemanding work or performing routine actions that don't need much attention, like walking to school or cooking simple foods. People tend to daydream during such activities. The importance of daydreaming lies in developing both creative and social skills. When the mind is not engaged in dealing with one's immediate situation or problem, then it is free to wander. A time of wandering allows the mind to create things. New inventions may be imagined, or possible solutions to a problem can be planned. For example, solutions to problems in relationships with other people may spring to mind. In fact, most daydreams involve situations with others. Perhaps these are daydreams based on past memories, or daydreams of what might be in the future. In either case, daydreams help us develop the appropriate skills we can use in real interactions with others. As brain specialist Dr. Marcus Raichle of Washington University explains: "When you don't use a muscle, that muscle really isn't doing much. But when your brain is supposedly doing nothing and daydreaming,... Question: Which statement would Dr. Raichle agree with? Options: A: The brain develops one's muscles. B: The brain and our muscles both need rest. C: The brain is a lot like a muscle. D: The brain is different from a muscle.

Read the article and select the best answer. Article: A federal agency on Tuesday called for a ban on all cellphone use by drivers -- the most far-reaching recommendation up to now -- saying its decision was based on a decade of investigations into distraction-related accidents, as well as growing concerns that powerful mobile devices are giving drivers even more reasons to look away from the road. As part of its recommendation, the National Transportation Safety Board is urging states to ban drivers from using hands-free devices, including wireless headsets. No state now has made laws to ban such activity, but the Board said that drivers faced serious risks from talking on wireless headsets, just as they do by taking a hand off the wheel to hold a phone to their ears. However, the concern was heightened by increasingly powerful phones that people can use to send e-mails, watch movies and play games. "Every year, new devices are being on sale." she said. "People are attracted to update their Facebook page, to play music with cellphone, as if sitting at a desk. But they are driving a car." The agency based its recommendation on evidence from its investigation of numerous crashes in which electronic distraction was a major contributing factor. Ms. Hersman said she understood that this recommendation would be unwelcome in some circles, given the number of drivers who talk and text. But she compared distracted driving to drunken driving and even smoking, which required wholesale cultural shifts to change behavior. "It's going to be very unpopular with some people." she said. "We're not here to win a popularity contest. We're here to do the right thing. This is a difficult recommendation, but it's the right recommendation and it is time." The agency's recommendation is not required for states to adopt such a ban. And it won't likely be agreed upon by state lawmakers who are unwillingly to anger those who have grown accustomed to using their device behind the wheel. The ban also deserves attention because it is the first call by a federal agency to end the practice... Question: Ms Hersman thinks that distracted driving, drunken driving and smoking _ . Options: A: are just common behaviors B: can be shifted to behaviors C: are behaviors to be changed D: are just cultural behaviors

Read the article and select the best answer. Article: The term "Industry 4.0" refers to the fourth industrial revolution. The first industrial revolution was the production of goods with machines like steam engines, which was followed by the second industrial revolution that introduced mass production with the help of electric power, followed by the digital revolution --the use of electronics and IT in production. Industry 4.0 is a high-tech project, which promotes the computerization of manufacturing . The basic principle of Industry 4.0 is that by connecting machines, work pieces and systems, we are creating intelligent networks along the entire value chain that can control each other automatically. The goal is the Smart Factory, which adapts well and uses resources efficiently as well as linking customers and business partners with great intelligence. Technological basis are the Internet systems and advanced factories. Experts believe that Industry 4.0 could be a reality in about 10 to 20 years. So, what effects does this change have on the classic manufacturing? According to an expert, "it is highly likely that the world of production will become more and more networked until everything is connected with everything else." Networks and processes have so far been limited to one factory. But in the time of Industry 4.0, the boundaries of individual factories will most likely no longer exist. Instead, they will be lifted in order to inter-connect multiple factories or even geographical regions. How is an Industry 4.0 factory different from a today's factory? In current industry environment, providing high-end quality service or product with the least cost is the key to success. Factories are trying to increase their profit as much as possible. In the time of Industry 4.0, various data sources are available to provide worthwhile information about different aspects of the factory. Using data for understanding the current condition and checking faults and failures is a natural thing. _ will enable these connected systems to manage themselves independently, work... Question: The writer's attitude toward Industry 4.0 can best be described as _ . Options: A: supportive B: negative C: doubtful D: cautious
