      In the near term, the goal of keeping AI’s impact on society beneficial motivates research in many areas, from economics and law to technical topics such as verification, validity, security and control. Whereas it may be little more than a minor nuisance if your laptop crashes or gets hacked, it becomes all the more important that an AI system does what you want it to do if it controls your car, your airplane, your pacemaker, your automated trading system or your power grid. Another short-term challenge is preventing a devastating arms race in lethal autonomous weapons.
       In the long term, an important question is what will happen if the quest for strong AI succeeds and an AI system becomes better than humans at all cognitive tasks. Such a system could potentially undergo recursive self-improvement, triggering an intelligence explosion leaving human intellect far behind. By inventing revolutionary new technologies, such a superintelligence might help us eradicate war, disease, and poverty, and so the creation of strong AI might be the biggest event in human history. Some experts have expressed concern, though, that it might also be the last, unless we learn to align the goals of the AI with ours before it becomes superintelligent.
      There are some who question whether strong AI will ever be achieved, and others who insist that the creation of superintelligent AI is guaranteed to be beneficial. At FLI we recognize both of these possibilities, but also recognize the potential for an artificial intelligence system to intentionally or unintentionally cause great harm. We believe research today will help us better prepare for and prevent such potentially negative consequences in the future, thus enjoying the benefits of AI while avoiding pitfalls.

According to paragraph 3, which information is incorrect about the future of AI?

As Chinese society changes, higher education is undergoing major transformations. The university model of the United States and other Western countries has a powerful influence. New trends in Chinese higher education are attracting the attention of global educators. Since the establishment of Western-oriented modern universities at the end of nineteenth century, Chinese higher education has continued to evolve. Over the past two decades, however, tremendous economic development in China has stimulated reforms in higher education that have resulted in some remarkable changes.

The first modern institution, Peiyang University, was founded in Tianjin. The university changed its name to Tianjin University in 1951 and became one of the leading universities in China: Next, Jiaotong University was founded in Shanghai in 1896. In the 1950s, most of this university was moved to Xi'an, an ancient capital city in northwest China, and became Xi'an Jiaotong University; the part of the university remaining in Shanghai was renamed Shanghai Jiaotong University.

Tianjin University celebrated its hundredth anniversary in 1995, followed by Xi'an Jiaotong and Shanghai Jiaotong Universities in 1996. Other leading universities, such as Zhejiang University (1897), Beijing University (1898), and Nanjing University (1902) also recently celebrated their hundredth anniversaries, one after another. These celebrations marked the beginning of a new chapter in Chinese higher education.

Tianjin University was founded in _______.

Do you think you're smarter than your parents and grandparents? According to James Flynn, a professor at a New Zealand university, you are! Over the course of the last century, people who have taken IQ tests have gotten increasingly better scores-on average, three points better for every decade that has passed. This improvement is known as "the Flynn effect," and scientists want to know what is behind it.
IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what was happening in the 20th century that was helping people achieve higher scores on intelligence tests?
Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better on any test. Others have pointed to better nutrition since it results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles, with teachers encouraging children to learn by discovering things for themselves rather than just memorizing information. This could prepare people to do the kind of problem solving that intelligence tests require.
Flynn limited the possible explanations when he looked carefully at the test data and discovered that the improvement in scores was only on certain parts of the IQ test. Test takers didn't do better on the arithmetic or vocabulary sections of the test; they did better on sections that required a special kind of reasoning and problem solving. For example, one part of the test shows a set of abstract shapes, and test-takers must look for patterns and connections between them and decide which shape should be added to the set.
According to Flynn, this visual intelligence improves as the amount of technology in our lives increases. Every time you play a computer game or figure out how to program a new cell phone, you are exercising exactly the kind of thinking and problem solving that helps you do well on one kind of intelligence test. So are you really smarter than your parents? In one very specific way, you may be.a

Until recently, hunting for treasure from shipwrecks was mostly fantasy; with recent technological advances, however, the search for sunken treasure has become more popular as a legitimate endeavor. This has caused a debate between those wanting to salvage the wrecks and those wanting to preserve them.
Treasure hunters are spurred on by the thought of finding caches of gold coins or other valuable objects on a sunken ship. One team of salvagers, for instance, searched the wreck of the RMS Republic, which sank outside the Boston harbor in 1900. The search party, using side-scan sonar, a device that projects sound waves across the ocean bottom and produces a profile of the sea floor, located the wreck in just two and a half days. Before the use of this new technology, such searches could take months or years. The team of divers searched the wreck for two months, finding silver tea services, crystal dinnerware, and thousands of bottles of wine, but they did not find the five and a half tons of American Gold Eagle coins they were searching for.
Preservationists focus on the historic value of a ship. They say that even if a shipwreck's treasure does not have a high monetary value, it can be an invaluable source of historic artifacts that are preserved in nearly mint condition. But once a salvage team has scoured a site, much of the archaeological value is lost. Maritime archaeologists who are preservationists worry that the success of salvagers will attract more treasure-hunting expeditions and thus threaten remaining undiscovered wrecks. Preservationists are lobbying their state lawmakers to legally restrict underwater searches and unregulated salvages. To counter their efforts, treasure hunters argue that without the lure of gold and million-dollar treasures, the wrecks and their historical artifacts would never be recovered at all.

Is there life on Mars? Many people have (1) ______ about this question. Some writers    of science-fiction think of people from Mars as little green creatures. Others imagine 'Martians' as monsters with many eyes.
In studying this planet, astronomers have found that life may be possible on Mars. The first (2) _____ of this is that Mars has seasons, just like Earth. In other words, Earth's seasons, such as spring or summer, occur on Mars too. Because these seasons exist, it may be possible for (3) ____and other higher life forms to be found on Mars.
Astronomers also think that perhaps a small (4) ______ of  water vapor could be  found  on Mars. In 1887, an Italian astronomer, Giovanni Schiaparelli, discovered markings on Mars' surface. These markings looked like canals. This finding led astronomers to believe that since water exists on Mars, life forms could exist as well.
 However, there are others who feel that life on Mars is not possible. This is because there is little or no trace of oxygen on the planet. In 1965, the Mariner IV capsule managed to take photographs of the planet. It discovered that the only forms of  life found are vegetation like fungi and mosses. (5) ______ people remain fascinated by the idea that there could one day be life on Mars.

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question. 
Though gambling is typically associated with casino games, strategic sports betting is rapidly gaining in popularity – and that's a whole other ball game, Prof. Dannon explains. "Sports gamblers seem to believe themselves the cleverest of all gamblers. They think that with experience and knowledge – such as player's statistics, manager's habits, weather conditions, and stadium capacity – they can predict the outcome of a game better than the average person."
But in a study published in the journal Psychopathology, Prof. Dannon and Dr. Ronen Huberfeld of the Beer Yaakov Mental Health Center determined that neither betting experience nor knowledge of the arcane details of the game is connected to successful betting outcomes. Indeed, he says, the two most successful gamblers in their study had no prior experience in gambling or knowledge of the sport in question. This should inform how psychologists approach sports gamblers, who need to be treated using different methods than their casino-addicted counterparts. For their study, the researchers focused on the field of soccer betting, one of the most popular and growing forms of sports gambling. They recruited three groups of participants, including 53 professional sports gamblers, 34 soccer fans who were knowledgeable about the sport but had never gambled, and finally, 78 non-gamblers with no prior knowledge of soccer at all. All participants were asked to place bets on the final scores of the 16 second-round matches of the Champion's League, organized by the Union of European Football Associations. This model mimics how gamblers actually put their money on the games, where they need to bet on exact scores to win.
Although those who had prior knowledge of soccer were expected to have a higher success rate, the researchers discovered that, in fact, their success rate was no better than those of the other two groups. Interestingly, the two participants with the most successful record, correctly betting on seven out of the 16 games each, hailed from the group with no prior understanding of the sport.
This doesn't indicate that there is an advantage to inexperience, says Prof. Dannon – many others in the third group were unable to predict any of the results correctly. But the outcome exposes the myth of knowledge as a powerful betting advantage. The sense of control that encourages sports gamblers in their betting is just an illusion.

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 questions:
The Internet started out as a limited network called the ARPANET (Advanced Research Projects Agency Network). It was a network of computers that allowed communication even if computer became non- functioning. It was the academic and scientific community that adopted Internet, using a protocol called TCP/IP. TCP/IP allows a number of different network computers to be connected together. This is called the Internet. The Internet allows the creation the World Wide Web or the Web for short. The Web consists of Internet sites that allow data to be shared by others. Aside from making the Web possible, the Internet also makes e-mail, chat rom and file-sharing and telephoning possible. It even allows people to watch media and play games.
The Web can be read in a browser. A browser is simply a software program that uses HTTP (Hyper Text Transfer Protocol) data transmission. This will allow you to view Web pages. HTTP let you browser read the text, graphics, animation, video and music that are on the Web page. It also enables you to click on a link on the page using the mouse. The links on a Web page that guide you to go from one Web page to another are called hyperlinks. A Web page usually contains many hyperlinks so that you can “browse” the Internet. It is much like reading a book. You can go from page to page and get new information. One example of a browser is Internet Explorer. In the address box of your browser, you can type in an address called a URL for “uniform resource locator”.
To be able to use the Internet, you must have a computer with an Internet connection and software that lets you view that Web pages. Internet connection is called a dial-up connection. It needs the use of your telephone to connect your computer to an Internet service. A faster type of connection is called broadband. This requires a cable or some other equipment. If you turn on the computer with a broadband connection, it connects you the Internet at a time.

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 questions:
Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear
The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores
In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed- species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases
The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen
Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

According to the information in the passage, all of the following terms refer to ants beginning to the genus Formica EXCEPT

National parks play a highly valuable role in documenting climate change. Researchers have utilized the vast tracts of pristine wilderness to collect data on species and habitats. At first, they collected observational data on foot; now, they use sophisticated methods such as aerial surveillance with drones like those used in Northrop Grumman’s Wildlife Challenge to collect information on polar bears.
Observational longitudinal data collection shows the effects of climate change that impact vegetation and animal species. The pika is the perfect example of an animal who may need to be relocated from the parks due to climate change, as described in Smithsonian Magazine. The park service is taking this very seriously. “It is … openly discussing the possibility of “assisted migration”: manually relocating some animals and plants if it turns out they can’t survive within the park’s changing landscapes.”
National park research also documents glacier retreat, finding that some ice fields have lost as much as 85 percent in the last five decades, according to U.S. Geological Survey. Glacier Park might be recognizable only as a historical name by 2030, it projects. It’s not just glaciers retreating. The Conversation notes that national park data shows that trees are also affected by climate change: “Climate change is killing trees due to increased drought, changes in wildfire patterns and increased bark beetle infestations. Tracking of trees in … national parks has contributed to a database that revealed how climate change has doubled tree mortality since 1955 across the western United States.”
We should not forget that at its inception, the National Parks Service’s long-term intention was to protect the parks and “leave them unimpaired for the enjoyment of future generations.”

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 questions:
Rachel Carson was bom in 1907 in Springsdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master’s degree in 1933. In 1936, she was hired by the US Fish and Wildlife Service, where she worked most of her life.
Carson’s first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean’s surface, emphasizing human history as well as geology and marine biology. Her imagery and language had a poetic quality. Carson consulted no less than 1, 000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers.
In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokesmen for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President’s Science Advisory Committee.

Which of the following was not mentioned in the passage as a source of information for The Sea Around Us?

A report from the United Nations given at the conference unveils how worrying the pollution caused by plastic utensils, especially plastic bags, is becoming. In a single minute, the world consumes one million plastic bottles; in a year, the world consumes five billion single-use plastic bags, according to Vietnamplus. The scary fact is that such plastic bottles and bags are not properly treated, as each year, the world discharges 300 million tons of plastic waste, accounting for some 10% of all solid waste, putting the environment and human health under tenterhooks, according to the news site.
The conference also drew attention to another fact: “For a plastic bag that can be used for five minutes, it takes five seconds to produce, one second to discard, but 500 to 1,000 years to become totally decomposed,” says Vietnamplus.
In another message given by the UN General Secretary and delivered at the conference, it is reported that since more than eight million tons of plastic bags end up in the oceans each year, “microplastics in the seas now outnumber stars in our galaxy.” “If present trends continue, by 2050 our oceans will have more plastic than fish,” Dan Tri reports, quoting Caitlin Wiesen, country director of the UN Development Programme in Vietnam.
These above-mentioned fearful facts, however, are not merely global issues, but domestic problems as well, according to local media. Many local news outlets, when relating data from the conference, point out that white pollution – a term used to indicate the overwhelming discharge of plastic bags into the environment – is even getting worse in Vietnam than elsewhere.

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 questions:
How is the news different from entertainment? Most people would answer that news is real but entertainment is fiction. However, if we think more carefully about the news, it becomes clear that the news is not always real. The news does not show us all the events of the day, but stories  from a small number of chosen events. The creation of news stories is subject to specific constraints, much like the creation of works of fiction. There are many constraints, but three of the most important ones are: commercialism, story formulas, and sources.
Newspapers, radio, and TV stations are businesses, all of which are rivals for audiences and advertising revenue. The amount of time that the average TV station spends on news broadcasts has grown steadily over the last fifty years - largely because news is relatively cheap to produce, yet sells plenty of advertising. Some news broadcasts are themselves becoming advertisements. For example, during one week in 1996 when the American CBS network was airing a movie about the sinking of the Titanic, CBS news ran nine stories about that event (which had happened 84 years before). The ABC network is owned by Disney Studios, and frequently runs news stories about Mickey Mouse. Furthermore, the profit motive drives news organizations to pay more attention to stories likely to generate a large audience, and to shy away from stories that may be important but dull. This pressure to be entertaining has produced shorter, simpler stories: more focus on celebrities than people of substance, more focus on gossip than on news, and more focus on dramatic events than on nuanced issues.
As busy people under relentless pressure to produce, journalists cannot spend days agonizing over the best way to present stories. Instead, they depend upon certain story formulas, which they can reuse again and again. One example is known as the inverted pyramid. In this formula, the journalist puts the most important information at the beginning of the story, than adds the next most important, and so on. The inverted pyramid originates from the age of the telegraph, the idea being that if the line went dead halfway through the story, the journalist would know that the most crucial information had at least been relayed. Modern journalists still value the formula for a similar reason. Their editors will cut stories if they are too long. Another formula involves reducing a complicated story into a simple conflict. The best example is "horse race" election coverage. Thorough explication of the issues and the candidates' views is forbiddingly complex. Journalists therefore concentrate more on who is winning in the opinion polls, and whether the underdog can catch up in the numbers than on politicians' campaign goals.
Sources are another constraint on what journalists cover and how they cover it. The dominant sources for news are public information officers in businesses and government offices. The majority of such officers try to establish themselves as experts who are qualified to feed information to journalists. How do journalists know who is an expert? In general, they don't. They use sources not on the basis of actual expertise, but on the appearance of expertise and the willingness to share it. All the major news organizations use some of the same sources (many of them anonymous), so the same types of stories always receive attention. Over time, the journalists may even become close friends with their sources, and they stop searching for alternative points of view. The result tends to be narrow, homogenized coverage of the same kind.

Read the passage carefully and choose the correct answer.

University Entrance Examination is very important in Vietnamese students. High school graduates have to take it and get high results to be admitted to universities. The pressure on the candidates remains very high despite the measures that have been taken to reduce the heat around these exams, since securing a place in a state university is considered a major step towards a successful career for young people, especially those from rural areas or disadvantaged families. In the year 2004, it was estimated that nearly 1 million Vietnamese students took the University Entrance Examination, but on average only 1 out of 5 candidates succeeded.  Normally, candidates take 3 exam subjects, and each lasts; 180 minutes for the fixed group of subjects they choose. There are 4 fixed groups of subjects: Group A: Mathematics, Physics, and Chemistry; Group B: Mathematics, Biology, and Chemistry; Group C: Literature, History, and Geography; Group D: Literature, Foreign Language, and Mathematics.

In addition to universities, there are community colleges, art and technology institutes; professional secondary schools, and vocational schools which offer degrees or certificates from a-few-month to 2-year courses. According to Vietnam's Ministry of Education and Training, there are currently 23 non-public universities, accounting for 11% of the total number of universities. These non-public universities are currently training 119,464 students, or 11.7% of the total number of students. The government is planning to increase the number of non-public universities to 30% by 2007.
