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." We can conclude from the article that the researchers think that _ . A) people should be true to their feelings B) smiling helps to put people in a good mood and become more efficient C) it is unnecessary to cultivate positive emotions D) deep acting can improve mood in the long run

As the oldest university in the English-speaking world, Oxford is a unique and historic institution. There is no clear date of foundation, but teaching existed at Oxford in some form in 1096 and developed rapidly from 1167, when Henry II banned English students from attending the University of Paris. From 1878, academic halls were established for women and they were admitted to full membership of the University in 1920. Five all-male colleges first admitted women in 1974. St Hilda's College, which was originally for women only, was the last of Oxford's single sex colleges. It has admitted both men and women since 2008. By 1200, the town of Cambridge had at least one school of some distinction. Then, in 1209, some scholars settled there. By 1226 the scholars were numerous enough to have set up an organisation, and seem to have arranged regular courses of study, taught by their own members. From the start there was conflict between the town and the students. Students, usually aged about fourteen or fifteen, often caused disturbances; citizens of the town, on the other hand, were known to overcharge for rooms and food. King Henry III took the scholars under his protection as early as 1231 and arranged for them to be sheltered from exploitation by their landlords. The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts. Founded in 1861 in response to the increasing industrialization of the United States, MIT adopted a European university model and stressed laboratory instruction in applied science and engineering. The current 168-acre campus opened in 1916 and extends over 1 mile (1.6 km) along the northern bank of the Charles River basin. On April 29, 1911, Tsinghua Xuetang began its first term of study, and from that year on, the Tsinghua's anniversary has fallen on the last Sunday of April. Following the outbreak of the War of Resistance against Japan in 1937, Tsinghua University, Peking University and Nankai University combined to form the National... When the University of Cambridge was set up, _ . A) there were too many scholars B) students were mostly adults C) King Henry III gave much help D) the town people were very friendly

Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include. "I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene. The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented reality, a technology already available on smartphones and tablets that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would _ showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you. "As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. "We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device that's hundreds and hundreds of dollars." Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this is a step there. " One of the possible functions of the smartphone-like glasses is to _ . A) program the opening hours of a bar B) supply you with a picture of the future C) provide information about your surroundings D) update the maps and GPS in your smartphones
