Read the article and select the best answer. Article: Exhausted and unhappy, you still have to squeeze a smile to your friends, or teachers. That's just life, you may think. But new research suggests that putting on a fake smile can worsen people's mood and even lower work efficiency. Lead researcher Brent Scott with other researchers studied a group of bus drivers for two weeks. They tried to find out what happened when the drivers were involved in "surface acting" or fake smiling, and the opposite, "deep acting" which means people put on real smiles by recalling pleasant memories or thinking about their current situation more positively. The results showed that on days when drivers were forced to smile, they felt depressed and didn't want to work. On days when they smiled due to positive thoughts, their mood improved a lot as well as their work efficiency. The research goes against the popular belief among companies that employees should be cheerful to customers at all times. They include employees of shops, banks, call center workers and others who have face-to-face contact with members of the public. "Smiling for the sake of smiling can lead to emotional exhaustion and coldness, and that's bad for the organization," Scott told the Daily Mail. The study also showed that women were harmed more by fake smiling than men. Their mood and work performance both worsened more. But they were helped more by deep acting -- their mood became better and they worked more efficiently. However, while deep acting seemed to improve mood in the short term, Scott says it's not a long-term solution for unhappiness. "There have been some suggestions that if you do this over a long period that you start to feel inauthentic ," Scott said. "You may be trying to cultivate positive emotions, but at the end of the day you may not feel like yourself anymore." Question: According to the article, which of the following statements about "fake smiling" is TRUE? Options: A: It is good for the business but bad for the employees. B: It doesn't work on people who are emotionally expressive. C: It is a widely accepted cultural practice in the US. D: It causes more harm to women than men.

Read the article and select the best answer. Article: Have you ever noticed advertisements which say "Learn a foreign language in 6 weeks, or your money back! From the first day your pronunciation will be excellent. Just send..." and so on? Of course, it never happens quite like that. The only language that is easy to learn is one's mother tongue. And think how much practice that gets! Before the Second World War people usually learnt a foreign language in order to read the literature of the country. Now speaking a foreign language is what most people want. Every year millions of people start learning one. How do they do it? Some people try at home, with books and records of tapes; some use radio or television programmes; some use computers and network; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like learning a foreign language at school. A few people try to learn a language fast by studying for 6 or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary. They need the language in order to do their work better. For example, scientists and doctors chiefly need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the student's work for him. Question: According to some advertisements, you _ . Options: A: have to pay your money if you cannot master a foreign language in 6 weeks B: needn't pay you money if you cannot learn a foreign language in 6 weeks C: must pay your money if you cannot master a foreign language in 6 weeks D: will be paid much money if you cannot learn a foreign language in 6 weeks

Ques: Read the article and select the best answer. Article: Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment. Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school inprefix = st1 /New Jerseyhad to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area. Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health. Some governments have realized how serous the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce. Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods. Question: From the text we know that _ . Options: A: chromium can poison people when there is a wind B: chromium pollution makes the local government close the school C: Some governments don't realize how serious the problems are until people suffer a lot from harmful waste D: about two-thirds of the waste can pollute the environment

Ques: Read the article and select the best answer. Article: Contestants from around the world met in Pomona, California, this month to test their skills at things like driving a car, walking down stairs, and opening doors. Sounds easy, right? But the competitors weren't people--they were robots! The bots were participating in the final round of the US's DARPA(Defense Advanced Research Projects Agency) Robotics Challenge. This event, which took place on June 5-6, tested robots on how well they could respond during a disaster and the winning team finally took home a $2 million grand prize. The DARPA challenge was created after the 2011 Fukushima nuclear disaster in Japan. An earthquake caused a tsunami, which damaged a nuclear power plant. Workers at the plant needed to shut off an important valve , but it was too dangerous for humans to reach it. The US scientists at DARPA wondered whether the disaster could have been avoided if a robot had been sent to do _ . So they set up the robotics competition. Turning a valve was just one task a robot might have to perform when entering a disaster zone. In addition to doing this, robots participating in the challenge had to navigate a course containing several other tasks: driving and exiting a vehicle, opening a door, walking over or clearing objects, cutting a hole in a wall, plus climbing a flight of stairs. Teams had to complete the challenge in one hour, and points were awarded based on how quickly the robots completed a task. They didn't have to attempt all the tasks. To make things even more realistic, challenge organizers caused short computer-system blackouts that prevented robots and the human operators controlling them from communicating. That means teams had to program their robots to be partially autonomous . Robots also couldn't be attached to anything that could keep them from falling down, which happened a lot. Question: What do we know about this year's DARPA challenge? Options: A: It lasted five days. B: It was held in Japan. C: Its winner got a cash prize. D: Its winner will work in Fukushima.
