Social networking sites such as Facebook and MySpace do not help you make more  genuine close friends, according to a survey by researchers who studied how the websites are changing the nature of friendship networks. Although social networking on the internet helps people to collect hundreds or even thousands of acquaintances, the researchers believe that face to face contact is nearly always necessary to form truly close friendships.  “Although the numbers of friends people have on these sites can be massive, the actual number of close friends is approximately the same in the face to face real world,” said psychologist Will Reader, from Sheffield Hallam University. Social networking websites such as Facebook, Bebo and MySpace have taken off rapidly in recent years. Facebook was launched initially in 2004 for Harvard University members but has since expanded to more than 34 million users worldwide. MySpace, which was set up in 2003, has more than 200 million users and was bought by Rupert Murdoch’s News Corporation in 2005 for $580m (£285m). Previous research has suggested that a person’s conventional friendship group consists of around 150 people, with five very close friends but larger numbers of people whom we keep in touch with less regularly. This figure is so consistent that scientists have suggested it is determined by the cognitive constraints of keeping up with large numbers of people. But Dr. Reader and his team have found that social networking sites do allow people to stretch this figure. The team asked more than 200 people to fill in questionnaires about their online networking, asking for example how many online friends they had, how many of these were close friends and how many they had met face to face. The team found that although the sites allowed contact with hundreds of acquaintances, as with conventional friendship networks, people tend to have around five close friends. Ninety per cent of contacts whom the subjects regarded as close friends were people they had met face to face. “People see face to face contact as being absolutely imperative in forming close friendships,” added Dr. Reader. He told the British Association Festival of Science in York that social networking sites allow people to broaden their list of nodding acquaintances because staying in touch online is easy. “What social network sites can do is decrease the cost of maintaining and forming these social networks because we can post information to multiple people,” he said.  But to develop a real friendship we need to see that the other person is trustworthy, said Dr. Reader. "What we need is to be absolutely sure that a person is really going to invest in us, is really going to be there for us when we need them … It’s very easy to be deceptive on the internet."

Go is a game that has been around for 3000 years. It is widely accepted as the most challenging strategy game that exists. It takes years of playing for several hours every day to master the game. In other words, even though it has simple rules, it is not a simple game to excel at. Surprise! Deep Mind managed to create a machine that could master the game, without being programmed with explicit rules and without being taught by a professional Go player. AlphaGo mainly played against itself and learned from this self-play. At its core, it learned like a human learns, by looking at the board, evaluating the options, making moves, and learning from mistakes - it just did it a lot faster than any human can. This is extremely exciting because, at its core, what it means is that computer scientists have had all the tools they needed to do this for years. Neural networks have been known about and discussed since the middle of the last century. All it really took was simply getting creative with them, applying them in new ways. AlphaGo beating the world’s best Go player proves that AI has the potential to do anything. It can learn anything and understand anything, and from that learning and understanding it can accomplish what humans can accomplish in a much shorter period of time. You’re probably wondering what this all means. We’re much closer to the dream of an AI best friend than most of us would have dared to imagine a few years ago. AlphaGo can learn the most complex, intuition and creativity based logic game known to man and it didn’t do so through a finite database or search trees alone. It learned from practice and experience, just like we do, and the ability to create amazing new solutions to ancient puzzles suggests a realm of digital creativity never before fathomed. AlphaGo is not like other game playing AIs that have come before it. It is the future of intelligent and intuitive machines, one that we plan to turn toward more than just board games. From practical applications to that friend you’ve been hoping for, AlphaGo is sure to be the first of a new generation of self-learning intuitive AIs that go above and beyond the limited calculating capacities of its older siblings and contemporaries. The AI winter is over.

Read the following passage and choose the best answer (A, B, C, D):
A generation gap in the workplace can make workers both young and old feel inferior, as well as hamper productivity and teamwork. Differences between generations can be seen in work ethics, habits and communication styles. Younger workers might fear not being taken seriously by their older colleagues, while older workers might fear that their experience is not valued but replaced by workers with knowledge of more current technology. However, members of each generation can close the gap between them if they’re willing to meet one another halfway. Older workers can show respect to the younger set by asking for their opinions and recognizing their contributions to the workplace as valid, or complimenting them on a job well done. Younger workers can show their elders respect by asking for advice on how to manage a situation with work, based on the older worker’s many years of experience. It’s important for both entry- and senior-level workers to see each other as equals, regardless of the type of position in which they work. No one wants to feel inferior or irrelevant just because of their age. Rather, a generation gap at work can be a learning opportunity. Workers can also put themselves in their colleagues’ shoes to determine what might be bothering them about their generational age difference. If a person is much older than another, perhaps it is bitterness about fewer job opportunities, or fear that a younger worker might seem more relevant and edge him out of his job. If workers open their minds to understand where co-workers are coming from, it can help ease any tension between them and appreciate each other’s work contributions.  If age seems to be a problem for someone at the workplace, it can be helpful to do the very opposite of what a co-worker might expect from someone of a different age set due to stereotypes. For example, if a worker is considerably younger such as right out of college, she can share researched information to indicate that she knows what she’s doing, or show curiosity instead of upset to indicate emotional maturity if the person makes a disparaging remark about her youth. Older workers can maintain an enthusiastic attitude about work instead of showing boredom or bitterness from past experiences. Workers can, moreover, directly address the concern of age differences at work with the colleague at odds with them by asking the person for constructive advice on how to handle the issue. For example, older workers who are unfamiliar with new software that younger colleagues understand might acknowledge to them that they did the same tasks differently in years past but show interest in learning the program to keep up with modern technology. Learning to speak their technological language can make them feel more connected. Likewise, a younger worker can admit to being green on the work scene, but eager to gain experience by learning from senior colleagues.

Read the following passage and choose the best answer (A, B, C, D):
Stonehenge, the prehistoric stone circle in southern England, is one of the most distinctive and mysterious monuments in the world. The monument, which attracted more than one and a half million visitors last year, is thought to be up to 5,000 years old, and the heaviest stone weighs 38 tons. No one really knows how the stones got there, or the reason they look the way they do – but a piece removed from one of the stones six decades ago could bring some answers. At first glance, the new “discovery” - a cylinder of rock - might look unremarkable. But for Lewis and Robin Phillips, it meant one thing: their dad, Robert. In 1958, Robert Phillips worked on a major restoration project commissioned by the British government. The goal was to make the monument safer, and help historians better understand what Stonehenge was and why it was there. The team drilled through the largest of the sarsen rocks, removing three stone cores. Robert Phillips was gifted one as a souvenir. At the time, the core sample was considered to be “waste material,” Lewis said. “I think that the standards of the day, in conservation, were a bit different to what they are now,” Robert added. Six decades later, Robert - who’s now in his 90s - asked his sons to return the “waste material.” But what had become a family heirloom for the Phillips’ was “the Holy Grail” of Stonehenge for geologists, according to Susan Greaney, an archaeologist at English Heritage. “When the Phillips family first got in touch with us, we had no idea that this existed,” Greaney said. “We’d just assumed that they’d been thrown away.” In 1958, samples like this couldn’t provide much information - but now, Greaney added, it can help archaeologists understand where the stones were from and how they were transported. It could even provide clues to one of the biggest questions: why move all these rocks to one location? Right now, “we don’t know” is the answer to that, Greaney said. "We think this is a prehistoric temple. It’s aligned with the movements of the sun, so we think it’s some kind of ceremonial space. But exactly what the stones mean, why they built them in this way and set them up in the way we see today, there are lots of mysteries about Stonehenge that we have yet to get to the bottom of.

In 1988, a year before the Soviet Union collapsed, the 13th National Congress of the  Communist Party of Vietnam adopted a resolution to have “more friends and fewer enemies”. So it was not surprising when Vietnam expressed interest in joining ASEAN as early as 1992, or when it did in fact join in July 1995.   Vietnam’s membership of the grouping integrated its security with the whole of Southeast Asia and created a favourable environment for economic development. This, in turn, raised Vietnam’s global image, leading to increased cooperation with multiple players in the region and greater bargaining clout with super powers like the United States and China. As an ASEAN member, Vietnam has worked hard to secure peace and reconciliation among Southeast Asian nations, which were once deeply divided by war. Vietnam was the first Indochinese country to join ASEAN, and its move helped end confrontation between the Indochinese bloc and ASEAN. Vietnam has also helped ASEAN partner with non-regional players.  Vietnam also led efforts within ASEAN to ensure regional security. Soon after becoming a member, Vietnam signed the Treaty on the Southeast Asian Nuclear-WeaponFree Zone and was one of the founding members of the ASEAN Regional Forum. But the most proactive steps by Hanoi towards regional stability have revolved around disputes in the South China Sea. A direct claimant in the dispute, Vietnam, along with the Philippines, has made constant efforts to put the South China Sea on ASEAN’s agenda, ensuring conflict is dealt with in a constructive way. Vietnam has shown constant support for the Declaration on the Conduct of Parties in the South China Sea, ASEAN’s Six-Point Principles on the East Sea, and the soon-to-be-concluded Code of Conduct of Parties in the East Sea. Vietnam calls for the settlement of disputes by peaceful means on the basis of international law and the 1982 United Nations Convention on the Law of the Sea — including through regulations on respecting exclusive economic zones and the continental shelf of coastal countries. Vietnam has remained committed to ASEAN since it joined in 1995 and Vietnam is beginning to integrate further with the global community, and  cooperation with ASEAN will always be an important pillar in its foreign policy. But Vietnam’s interest in ASEAN is not
limited to security issues. Its leadership also drives efforts toward an ASEAN Economic Community (AEC).

On an Old Quarter thoroughfare of Hanoi, known as train street, locomotives rumble down an active track just inches away from homes and other buildings. The juxtaposition of train tracks and residential housing has made it hugely popular among travelers to the capital of Vietnam. But the municipal government of Hanoi has ordered that cafes alongside the heavily Instagrammed train tracks – which sprung up to cater to the tourism boom – must close. Authorities cite danger to human life as the primary motivator for the shutdown. The boiling point apparently came on Sunday, when a train traveling through Hanoi was forced to reroute because there were too many tourists on the tracks, which were built in 1902 by the French. “Though the railway cafes attract tourists, they are, in fact, violating some regulations,” Ha Van Sieu, vice chairman of the Vietnam National Administration of Tourism, told reporters at a press briefing. In 2018, Vietnam-based writer Dave Fox told CNN Travel that “overtourism is a new buzzword for something that has been going on a long time.” A longtime Hanoi resident, he watched as “train street” transformed from a cool novelty into a safety concern. “Travelers need to be mindful of optics,” he added. When it comes to overtourism, some destinations face more of a challenge than others. In Indonesia, moves have been made to greatly restrict traveler access to Komodo Island, home to the famous Komodo dragon. Initially, the country had considered shutting the island to tourists completely, but settled on a plan with limited access to visitors who could pay a high access fee. And nearby in Thailand, the heavily popular Maya Bay, made famous by the film “The Beach” has been closed since 2018 to repair the most severe outcome – environmental damage. 
2. According to Hanoi authorities, the reason for the shutdown is ___________

Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal. Nonverbal communication has been defined as communication without words. It includes apparent behaviors such as facial expressions, eyes, touching, tone of voice, as well as less obvious messages such as dress, posture and spatial distance between two or more people. Activity or inactivity, words or silence all have message value: they influence others and these others, in turn, respond to these communications and thus they are communicating. Commonly, nonverbal communication is learned shortly after birth and practiced and refined throughout a person's lifetime. Children first learn nonverbal expressions by watching and imitating, much as they learn verbal skills. Young children know far more than they can verbalize and are generally more adept at reading nonverbal cues than adults are because of their limited verbal skills and their recent reliance on the nonverbal to communicate. As children develop verbal skills, nonverbal channels of communication do not cease to exist although become entwined in the total communication process.

Read the following passage and choose the best answer (A, B, C, D):
English teenagers are to receive compulsory cooking lessons in schools. The idea is to encourage healthy eating to fight the country’s increasing obesity rate. It’s feared that basic cooking and food preparation skills are being lost as parents turn to pre-prepared convenience foods. Cooking was once regarded as an important part of education in England – even if it was mainly aimed at girls. In recent decades cooking has progressively become a minor activity in schools. In many cases the schools themselves have given up cooking meals in kitchens in the schools. But the rising level of obesity has led to a rethink about the food that children are given and the skills they should be taught. “What I want is to teach young people how to do basic, simple recipes like a tomato sauce, a bolognaise, a simple curry, a stir-fry – which they can use now at home and then in their later life”, said Ed Balls, the minister responsible for schools. The new lessons are due to start in September, but some school without kitchens will be given longer to adapt. There is also likely to be a shortage of teachers with the right skills, since the trend has been to teach food technology rather than practical cooking. Also the compulsory lessons for hands on cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believes it will be worth it. “If we’d done this thirty years ago we might not have the crisis we have got now about obesity and lack of knowledge about food and so on. Every child should know how to cook, not just so that they’ll be healthy, but because it’s a life skill which a real pleasure”. The renewed interest in cooking is primarily a response to the level obesity in Britain which is among the highest in Europe, and according to government figures half of all Britons will be obese in 25 years if current trends are not stopped

Nowadays, dozens of interventions are known that extend the lifespan of various living organisms ranging from yeast to mammals. They include chemical compounds, genetic interventions, and diets. Some targets of these interventions have been discovered. However, there is still no clear understanding of the systemic molecular mechanisms leading to lifespan extension. A group of scientists from Skoltech, Moscow State University and Harvard University decided to fill this gap and identify crucial molecular processes associated with longevity. To do so, they looked at the effects of various lifespan-extending interventions on the activity of genes in a mouse, a commonly used model organism closely related to humans. “In our lab, we subjected mice of different sexes and ages to 8 longevity interventions and analyzed gene expression changes induced by these treatments. After aggregating our data with the datasets published by other groups, we obtained gene activity profiles of 17 interventions. Although in general the effects produced by individual treatments turned out to be rather specific, a certain group of genes changed its expression in a similar way in response to different lifespan-extending interventions,” says the first author of the study, Alexander Tyshkovskiy. The scientists then applied the discovered biomarkers to search for other interventions with the same effect on their activity and, therefore, high potential for lifespan extension "Currently, we are validating these hits by testing their effect on the mouse lifespan. We hope that our biomarkers will significantly facilitate the search for new longevity interventions and help improve the healthspan and lifespan in rodents and, in the long term, in humans," says Alexander. 
2. According to paragraph 2, what approach did the scientists take to uncover the genetic mystery?

It is estimated that by 2050 more than two-thirds of the world's population will live in cities, up from about 54 percent today. While the many benefits of organized and efficient cities are well understood, we need to recognize that this rapid, often unplanned urbanization brings risks of profound social instability, risks to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues.
 How effectively these risks can be addressed will increasingly be determined by how well cities are governed. The increased concentration of people, physical assets, infrastructure and economic activities mean that the risks materializing at the city level will have far greater potential to disrupt society than ever before.
 Urbanization is by no means bad by itself. It brings important benefits for economic, cultural and societal development. Well managed cities are both efficient and effective, enabling economies of scale and network effects while reducing the impact on the climate of transportation. As such, an urban model can make economic activity more environmentally-friendly. Further, the proximity and diversity of people can spark innovation and create employment as exchanging ideas breeds new ideas.
 But these utopian concepts are threatened by some of the factors driving rapid urbanization. For example, one of the main factors is rural-urban migration, driven by the prospect of greater employment opportunities and the hope of a better life in cities. But rapidly increasing population density can create severe problems, especially if planning efforts are not sufficient to cope with the influx of new inhabitants. The result may, in extreme cases, be widespread poverty. Estimates suggest that 40% of the world's urban expansion is taking place in slums, exacerbating socio-economic disparities and creating unsanitary conditions that facilitate the spread of disease.
 The Global Risks 2015 Report looks at four areas that face particularly daunting challenges in the face of rapid and unplanned urbanization: infrastructure, health, climate change, and social instability. In each of these areas we find new risks that can best be managed or, in some cases, transferred through the mechanism of insurance.

The term “generation gap” may have been coined not long ago but the problem itself is as old as the hills. All sorts of conflicts and misunderstanding between younger and older generations occur in probably every family. Adults complain about arrogance and insensitivity of young people whereas the latter claim that their parents have no idea about what they are going through. There seems to be no perfect solution to this problem as the young and the old find it difficult, if not impossible, to communicate and accept opposite views. The fact that teenagers develop different values from those held by their parents leads to numerous conflicts. There are many reasons why the problem of generation gap arises. First of all, the period of adolescence is difficult. Teenagers are not children any longer, but they are no adults yet. They search for a sense of identity and crave independence. On the other hand, they depend on their parents financially and still need their parent consent when they want to go out, go for holidays, buy something expensive, invite friends home, etc. Very often teenagers treat their parents like enemies especially when they are not permitted to do one thing or another. Obviously, it is understandable when parents insist a teenager returns home before midnight. They have a wide knowledge of the world and all kinds of risks involved – reckless youngsters see no danger in walking alone in the middle of the night or getting a lift from a stranger who might be a serial killer. When children grow up and start their own families they are able to admit that their parents were usually right, although a bit overprotective at times  However, we must remember that adolescence is the period of making important decisions. Sixteen or seventeen-year-olds want to choose their career path or at least develop their talents, which in turn will enable them to decide upon a job later on. Secondly, it is in their late teens when they form their lifelong friendships, go for their first dates, analyze what qualities they will look for in their future partners. Unfortunately, a lot of parents do not want to accept the fact that their child is growing up and has the sole right to choose who she or he wants to become in the future. Such mothers and fathers often have their own idea what their child’s life should be. To my mind, this kind of behavior is really harmful and it can result in a very serious family conflict. Every now and then we meet forty-year-old people who accuse their parents of making them study the subject they hated or marrying the person they never loved. The generation gap problem, which usually disappears a few years later, in such families turns into an emotional wound which might never heal and the feeling of a wasted life on both parts. To sum up, although conflicts between teenagers and their parents are unavoidable, they definitely do not have to lead to an open war. My advice to parents is to try and treat teenagers as their equal partners and to accept their ideas. Teenagers should respect their mothers and fathers more, and be always ready to discuss serious problems with them. All in all, who else loves them more than their parents do?  
2. Which of the following best serves as the title for the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions:
If you were going to choose a job that involves travel, what would be your first choice? There are many jobs available today that give people opportunities to travel. Although may traveling careers sound fantastic, they also have disadvantages.
Being an au pair is an excellent way to not only go to different countries, but to live in different places around the world and really get a feel for the culture. Au pairs lives with the families they are placed with and take of children. Many parents include au pairs in family events and vacations, so they experience many aspects of the new culture while on the job. However, many of the activities are centered around the children, so they may not get to experience many things that interest adults.
For people who want a bit more freedom working abroad, being an English teacher maybe a good choice. There are English teaching jobs in almost countries in the world. People teaching English in other countries often have a chance to travel on the weekends around the country. One drawback is that many teachers often wind up hanging out with other English teachers, and they don’t have time to learn the country’s language.
The nickname “roadie” implies that this job involves life on the road. Roadies are people who work and travel with bands and provide technical support. Roadies can be lighting and stage crew who set up the stage and break it down before and after events. They can also be technicians helping band members with their instruments. International tours take a band’s crew to cities around the world, often requiring air travel. However, the crew doesn’t get much time off, so they may travel to several countries without seeing much besides concert venues and hotels.
Similarly, flight attendants often travel to cities around the world, but they don’t see much besides the inside of airplanes and hotels. However, when they do have time off, they can often fly at no cost, and family member can sometimes fly free as well. Its is widely thought that a flight attendant job is
glamorous, but flight attendants must deal with travel hassles, as well as security issues.
All jobs gave advantages and disadvantages whether or not you travel for work, so if you have the travel bug, keep these jobs in mind for the future.
