Q: Read the following article and select the best answer. Article: Vacation is a time for refreshment. In work, we are often called to think. Sometimes, it's good to give our brains a rest. Without a break, we may not be able to perform up to our potential. This can be a problem, not only for the employee, but for the employer as well. "The main benefit of vacation is for the worker to come back energized," says Weaver. "If they haven't had a break, then they're not coming back with new energy. They haven't had a chance to step back and get perspective , and come back with renewed enthusiasm." Long working hours without a break, insecurity about one's job, and other work-related worries can lead to burnout and stress. Humans can usually adapt to pressure, but not for a limitless amount of time. "It is a problem of relating good workers and having them loyal to the firm while they're _ ," says David Maume, PhD, professor of sociology at the University of Cincinnati. He says burnout can also affect employees' productivity, creativity, and effectiveness. In addition, high levels of stress are likely to be precursors to depression, which can hit both the employer and employee's pocketbook. Even people who manage to remain productive at work can have problems. If they're always at work, then they're not with their family and friends. If they're working while on vacation, for the time that they're on the job, they're not really present. An unbalanced emphasis on work can strain family and social life. When you come up for air, you may see that you're alone, or that your relationships have gone on without you. Question: Which of the following is the best title for the passage? - Why Workers Need Vacation - Why Workers Need New Energy - How to Deal with Daily Pressure - How to Spend Vacation Effectively
A: Why Workers Need Vacation

Q: Read the following article and select the best answer. Article: Soap operas from South Korea have been popular in China for two decades now. So, it is not the first time Chinese TV dramas have paled in comparison. But this time, the one-two punch from The Heirs and My Love From the Star really hurts. A senior official freely admitted to being an occasional participant in the vast club of Korean soap watchers. It has also been reported that he follows House of Cards, an American political thriller that would understandably fascinate him. His remark opened the flood gate of complaints about why we are falling behind in the creative industry. Most seem to agree that, given some content limits, China's television industry is not able to produce something like House of Cards, which is very dark and filled with conspiracy . But there is a concern about our inability to make something as entertaining as My Love from the Star, a Korean love story about a time-traveling professor and a proud movie star. Judging from Chinese shows in recent years, time travel is not strictly forbidden, but allowed when it is used as a background and handled with kid gloves. A series of palace dramas is built on the plot that the female leading character is transported from contemporary times back to ancient China, playing the game of an unhappy girl and a real prince coming to her rescue. There are many reasons why Chinese soap operas have become the favorite punching bag. Among them is the most important one that the industry itself has never set right its mechanism for operation. The role of the creator, the most important job for American TV series programming that is often taken on by the head writer, is vacant in China. Because Chinese television came from the film industry, few have realized that, unlike director-dominated films, TV is the art of the writer, which is accepted in almost all countries with highly developed television industries. Question: What can we learn about time travel? - Time travel is forbidden in Chinese shows. - Time travel can be used but not freely. - Time travel is only used in palace dramas. - Time travel stories are often about princes and princesses.
A: Time travel can be used but not freely.

Q: Read the following article and select the best answer. Article: 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. Question: What does the author say about the threat of robots? - It may constitute a challenge to computer progranmers. - It accompanies all machinery involving high technology. - It can be avoided if human values are translated into their language. - It has become an inevitable peril as technology gets more sophisticated.
A: It can be avoided if human values are translated into their language.
