U.N. diplomats abandoned efforts to draft a treaty that would outlaw human cloning. They will likely settle for a weaker statement, and won’t seek a widespread ban, officials said. The debate began when Italy introduced a document into the UN. to stop any attempt at cloning human life. The Belgians objected to the use of the term “human life” in the document, because they feared it would put a stop to all forms of human cloning.
[1] There is near universal support among the United Nations’ 191 members for a ban on reproductive cloning-creating cloned babies. [2] Many countries have wrestled over whether to allow cloning for stem cell and other types of research. [3] Indeed, many researchers believe that stem cells could be used to repair nerve tissue or cure diseases, including Alzheimer’s. [4] Stem cells are taken from embryos and cloned, but extracting these cells kills the embryo. Opponents say that this is equal to murder.

Which is the best place for the following sentence? “Another type of cloning is the cause of the controversy.”

Translators and interpreters for tech jobs of the future are expected to be one of the fastest growing occupations in the nation, according to a just released survey by Vietnamworks. Almost all positions for programmers, application developers, database and network administrators, engineers, designers, architects, scientists, technicians, and tech support will require bilingual or multilingual fluency. In just the last two years the demand for tech professionals with foreign language skills has increased more than two and one-half fold, said the survey, and the uptick shows no signs of abating anytime soon. Roughly 400,000 jobs are expected to open for interpreters (who focus on spoken language) and translators (who focus on written language) in the tech segment, between 2017 and 2020, says Tran Anh Tuan. Tuan, who works for the Centre for Forecasting Manpower Needs and Labour Market Information in Ho Chi Minh City doesn't include other industries in his prediction,
which are also recruiting ferociously for more people with these same language skills.
While that claim might seem a bit overblown (and amounts to little more than a guess by Tuan), it is clear that innovative technologies like robotics, 3D printing, drones, artificial intelligence   and virtual reality will create major upheavals in all sorts of labor markets, not just technology over     the next few years. In the last month alone, most every job posted on employment websites throughout Vietnam included the word bilingual. Far higher salaries go to people who work in high    tech positions and can speak a foreign language such as English in addition to Vietnamese, says Tran Quang Anh from the Posts and Telecommunications Institute of Technology.
Unfortunately, the surveys show that most graduating Vietnamese students are unable to do more than understand a few basic phrases of foreign languages, and practically none of them  can speak any foreign language coherently, The good paying jobs with high salaries and benefits are only available to translators and interpreters who specialize in high tech jobs, says Anh. But it's    not just English— graduates are needed with fluency in middle eastern languages like  Arabic, Farsi and Pashto (Afghani) as well as German, Japanese and Korean to name just a few. Spanish is  also in high demand in Vietnam, primarily because it is the second most common language in the US after English.
A recent tech expo in Hanoi sponsored by Vietnamworks and the Navigos Group attracted nearly 4,000 young tech graduates and recruiters from 14 leading companies looking to fill job  vacancies with skilled bilingual workers. The job applicants were young and industrious, said the recruiters. However, missing were candidates with the requisite language skills and most lacked  basic 'soft skills' such as written and verbal communication abilities to effectively communicate  even in their native Vietnamese language.
Notably, the recruiters said they considered language abilities and soft skills just as, if not more important, than academic ability. Yet virtually all the prospective academically qualified employees lacked even the most basic of interpersonal communication abilities.

Most forms of property are concrete and tangible, such as houses, cars, furniture or anything else that is included in one’s possessions. Other forms of property can be intangible and copyright deals with intangible forms of property. Copyright is a legal protection extended to authors of creative works, for example, books, magazine articles, maps, films, plays, television shows, software, paintings, photographs, music, choreography in dance and all other forms of intellectual or artistic property.
Although the purpose of artistic property is usually public use and enjoyment, copyright establishes the ownership of the creator. When a person buys a copyrighted magazine, it belongs to this individual as a tangible object. However, the authors of the magazine articles own the research and the writing that went into creating the articles. The right to make and sell or give away copies of books or articles belongs to the authors, publishers, or other individuals or organizations that hold the copyright. To copy an entire book or a part of it, permission must be received from the copyright owner, who will most likely expect to be paid.
Copyright law distinguishes between different types of intellectual property. Music may be played by anyone after it is published. However, if it is performed for profit, the performers need to pay a fee, called a royalty. A similar principle applies to performances of songs and plays. On the other hand, names, ideas, and book titles are accepted. Ideas do not become copyrighted property until they are published in a book, a painting or a musical work. Almost all artistic work created before the 20th century is not copyrighted because it was created before the copyright law was passed.
The two common ways of infringing upon the copyright are plagiarism and piracy. Plagiarizing the work of another person means passing it off as one’s own. The word plagiarism is derived from the Latin plagiarus, which means “abductor”. Piracy may be an act of one person, but, in many cases, it is a joint effort of several people who reproduce copyrighted material and sell it for profit without paying royalties to the creator. Technological innovations have made piracy easy and anyone can duplicate a motion picture on videotape, a computer program, or a book. Video cassette recorders can be used by practically anyone to copy movies and television programs, and copying software has become almost 'as easy as copying a book. Large companies zealously monitor their copyrights for slogans, advertisements, and brand names, protected by a trademark.

 It can be inferred from the passage that it is legal if     .

                  ENGLISH SPEELING
Why does English spelling have a reputation for being difficult? English was first written down when Christian monks came to England in  Anglo-Saxon (1)........... . They used the 23 letters of Latin to write down the sounds of Anglo-Saxon speech as they heard it. However, English has a (2)...............   range   of basic sounds (over 40) than Latin. The alphabet was too small, and so combinations of letters were needed to express the different sounds. Inevitably, there were inconsistencies in the way that letters were combined.
With the Norman invasion of England, the English language was put at risk. English survived, but the spelling of many English words changed to follow French (3)...... , and many French words were introduced into the language. The result was more irregularity.
When the printing press was invented in the fifteenth century, many early printers of English texts spoke other first languages. They made little effort to respect English spelling. Although one of the shortterm (4)................ of printing was to produce a number of variant spellings, in the long term it created    fixed spellings. People became used to seeing words spelt in the same way. Rules were drawn up, and dictionaries were put together which printers and writers could refer to. However, spoken English was not fixed and continued to change slowly - just as it still does now. Letters that were sounded in the Anglo- Saxon period, like the 'k' in 'knife', now became (5)............. Also, the pronunciation of vowels then had  little in common with how they sound now, but the way they are spelt hasn't changed.

The diary and the letter were the most extensively practiced forms of life writings in eighteenth- century America. From the numerous examples of these two types of writing from the period, a portrait of daily life of the period can be gleaned.
Many of the diaries that were kept during this period were life diaries by authors interested in maintaining day-to-day records of reflective self-examination, but some of the most compelling were situational diaries; those prompted by and limited to lengthy descriptions of personal reflections about a particular event. Three of the many situational journals of this period are those written by Sarah Kemble Knight, William Burd II, and Dr. Alexander Hamilton. Sarah Kemble Knight's diary of her five-month trip at the end of 1704 and the beginning of 1705 from Boston to New Haven to New York and back again to Boston was published more than a century later as The Journal of Madam Knight. Though this diary does include an account of the hardship that she encountered along the way, it is principally composed of humorous descriptions of and commentary on the hospitality that she was offered and the manners of those that she encountered. William Burd II kept two diaries to describe his experiences on a 1729 surveying expedition to settle a border dispute between Virginia and North Carolina. One of the diaries, History of the Dividing Line between Virginia and North Carolina, was published in 1842, while its companion, Secret Diary, was published in 1929. In these diaries, Burd used a humorous and satirical approach to describe not just the day-to-day events of the trip but also the characteristics which set his beloved Virginia culture apart from the (in his opinion) decidedly less praiseworthy culture of those non- Virginians that he encountered in his trip. Dr. Alexander Hamilton's Itinerarium (1744) describes a four- month voyage of discovery undertaken by Hamilton through the mid-Atlantic and New England colonies; in the diary that he kept of this trip. Hamilton provides considerable commentary on the social customs of various areas, comparing the customs and culture of the better homes of the American colonies with those of the great salons of Europe.
Letter-writing also held a place of importance in eighteenth-century America (indeed, the ability to produce cultured letters was considered a form of art), and many letters extant from that period provide insights into the culture, mores, and styles of written communication of that era. Many of the letter writers employed devices in common usage in European models of the time, demonstrating that letter writers felt a sense of cohesiveness with the cultured classes of Europe: John and Abigail Adams signed the names Lysander and Constantia to their early letters, while Thomas Jefferson created an elaborate dialogue between his head and his heart to discuss the nature of friendship in  a 1786 letter to Maria Cosway. The variety of purposes that these letters served provides additional insight into the priorities of the society of the time. The letters were used to cement love matches and friendships, as the previously mentioned letters did; they were the primary method for relaying news among family and friends who were scattered across various geographic locations; they were often used as a means of carrying out business in this era before more rapid long-distance communication; they were often used used as a way of sharing professional, social, or political ideas among leaders in various fields who perhaps had no other way to get together and exchange ideas.

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:
Industrialization came to the United State after 1790 as North American entrepreneurs increased productivity by reorganizing work and building factories. These innovations in manufacturing boosted output and living standards to an unprecedented extent; the average per capita wealth increased by nearly 1 percent per year - 30 percent over the course of a generation. Goods that had once been luxury items became part of everyday life.
The impressive gain in output stemmed primarily from the way in which workers made goods, since the 1790’s, North American entrepreneurs - even without technological improvements - had broadened the scope of the outwork system that made manufacturing more efficient by distributing materials to a succession of workers who each performed a single step of the production process. For example, during the 1820’s and 1830’s the shoe industry greatly expanded the scale of the outwork system. Tens of thousands of rural women, paid according to the amount they produced, fabricated the “uppers” of shoes, which were bound to the soles by wage-earning journeymen shoemakers in dozens of Massachusetts towns, whereas previously journeymen would have made the enduring shoe. This system of production made the employer a powerful “shoe boss” and eroded workers’ control over the pace and conditions of labor. However, it also dramatically increased the output of shoes while cutting their price.
For tasks that were not suited to the outwork system, entrepreneurs created an even more important new organization, the modem factory, which used power-driven machines and assemblyline techniques to turn out large quantities of well-made goods. As early as 1782 the prolific Delaware inventor Oliver Evans had built a highly automated, laborsaving flour mill driven by water power. His machinery lifted the grain to the top of the milt, cleaned it as it fell into containers known as hoppers, ground the grain into flour, and then conveyed the flour back to the top of the mill to allow it to cool as it descended into barrels. Subsequently, manufacturers made use of new improved stationary steam engines to power their mills. This new technology enabled them to build factories in the nation’s largest cities, taking advantage of urban concentrations of inexpensive labor, good transportation networks, and eager customers.

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:
In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.

If you ask any Vietnamese girl right now who she has a crush on, chances are you will encounter the name of the 20-year-old goalkeeper who plays for Vietnam national team. Bui Tien Dung made a name for himself in the AFC U23 Championship where he accurately blocked opponents' shots time after time and saved Vietnam’s chance at the championship in the process. Bui Tien Dung was born on February 28th, 1997 in a poor farming family in Thanh Hoa Province. Dung has loved soccer since he was a kid, but his family was so poor that they could not even
afford a plastic soccer ball for him and his brother. The Bui brothers had to resort to playing with balls made from scrap papers and old grapefruits.
Dung's parents recognized the brothers' passion for football and used the little money they had to support their sons' early training. When a big football club in the city announced a recruitment event, Dung convinced his younger brother to go to the tryout. He passed on the opportunity knowing that his parents could not afford to have both their sons gone to city.
While his younger brother training in the city, Dung's local training center went bankrupted and abruptly ended Dung's football career. For a year, instead of kicking balls, the young man worked as a construction worker to support his parents. He seemingly gave up on football.
Fate finally smiled on Dung when a football coach rediscovered him and sent him to train with a local football team. Reentering the football field, Dung wanted to play in a defense position but he was pushed to goalkeeping because of his height. At first, Dung was unhappy about his new position, but his parents advised him to follow and make the best out of it. And Dung did.
The young goalkeeper trained hard for his new position and patiently climbed up the ranks the following years. Through hard work, he was named the best goalkeeper of Vietnam's U19 division. Those who have worked with Dung described him as a likable young man. He is very respectful to others and speaks very little. However, when the gloves are on, the nice young man transforms into a fierce competitor and an unyielding goalkeeper.
At AFC U23 Championship, Dung finally reunited with his brother on the field. They fought battle after battle together with other amazing players on the team and helped Vietnam made history for Southeast Asian football.
Even though Vietnam came short of winning the championship, Dung and his teammates are already heroes and legends in the heart of Vietnamese people. They played fairly and lost with glory and grace.

By adopting a few simple techniques, parents who read to their children can considerably increase their children’s language development. It is surprising, but true. How parents talk to their children makes a big difference in the children’s language development. If a parent encourages the child to actively respond to what the parent is reading, the child’s language skills increase.
A study was done with two or three-year-old children and their parents. Half of the thirty children participants were in the experimental study; the other half acted as the control group. In the experimental group, the parents were given a two-hour training session in which they were taught to ask open-ended questions rather than yes-no questions. For example, the parent should ask, “What is the doggy doing?” rather than, “Is the doggy running away?” Experimental parents were also instructed how to expand on their children’s answer, how to suggest alternative possibilities, and how to praise correct answers.
At the beginning of the study, the children did not differ on levels of language development, but at the end of one month, the children in the experimental group were 5.5 months ahead of the control group on a test of verbal expression and vocabulary. Nine months later, the children in the experimental group still showed an advance of 6 months over the children in the control group.

"Most of us are interested in one kind of sport or another, even if we don't go in for it actively. Lots of people take up a particular sport at an early age, for example tennis, skiing, or ice-skating. If they get up to a suitably high standard, they may go in for local competitions or even championships. But special training is hard work and most young people don't keep it up. Many of them opt out when they come up against tough competition.

To become a professional in any sport, you have to go through with a strict training schedule. And it's not easy! It means doing without some of life's little pleasures, too. For example, to build up your physical strength you may have to stick to a special diet and give up some of your favorite foods. Smoking and alcohol are out, and to keep fit you have to work out regularly every day.

Sometimes it all pays off, but the road to success is long and there are no guarantees. No wonder that countless young talents decide to settle for a regular job instead, and, as far as professional sport is concerned, for looking on as spectators."

Read the passage below and choose one correct answer for each question.

In developing countries, people are sometimes unaware of the importance of education, and there is economic pressure from those parents who prioritize their children's, making money in the short term over any long-term benefits of education. Recent studies on child labor and, poverty have suggested that when poor families reach a certain economic threshold where families are able to provide for their basic needs, parents return their children to school. This has been found to be true, once the threshold has been breached, even if the potential economic value of the children's work has increased since their return to school.

Other problems are that teachers are often paid less than other professions; a lack of good universities and a low acceptance rate for good universities are evident in countries with a relatively high population density.

India has launched EDUSAT, an education satellite that can reach remote parts of the country at a greatly reduced cost. There is also ail initiative supported by several major corporations to develop a $100 laptop. The laptops have been available since 2007. The laptops, sold at cost, will enable developing countries to give their children a digital education. In Africa, an "e-school program" has been launched to provide all 600,000 primary and high schools with computer equipment, learning materials and internet access within 10 years. Volunteer groups are working to give more individuals opportunity to receive education in developing countries through such programs as the Perpetual Education Fund. An International Development Agency project started with the support of American President Bill Clinton uses the Internet to allow co-operation by individuals on issues of social development.

Dark matter in the universe is believed by some scientists to be a substance that is not readily observable because it does not directly refract light or energy. Its existence can only be deduced because of the effect that it has on surrounding matter. In fact, some members of the scientific community have argued that dark matter does not actually exist. Others, however, believe in its existence, in part because the scientific community does not have a complete understanding of gravita science. On the other hand, some would argue that it is the understanding of gravitational science that leads most scientists to believe in the existence of dark matter, because without dark matter, there are many cosmological phenomena
that are difficult to explain.
For example, dark matter in the universe may have a peculiar effect on the Milky Way galaxy. Some scientists believe that the interaction between dark matter and other smaller, nearby galaxies is causing the Milky Way galaxy to take on a warped profile. It has been asserted that not only does dark matter exist, it may also be responsible for the Milky Way’s unusual shape. The interaction referenced involves two smaller galaxies near the Milky Way, called Magellanic clouds, moving through an enormous amount of dark matter, which, in effect, enhances the gravitational pull that the two Magellanic clouds could have on the Milky Way and other surrounding bodies. Without the existence of the dark matter, the Magellanic clouds would not have sufficient mass to have such a strong effect on the bend of the Milky Way galaxy.
The strongest evidence for the validity of this hypothesis rests in Newtonian physics, and the hypothesis that anything with mass will exert a gravitational pull. The Milky Way and other galaxies with peculiar warped shapes are being molded by a gravitational force. However, there is nothing readily observable with sufficient mass that could cause such a high level of distortion via gravitational pull in the vicinity of the Milky Way. Therefore, something that is not easily observed must be exerting the necessary force to create the warped shape of the galaxy.
Aaron Romanowsky and several colleagues have questioned the effect that dark matter might have on galaxies. They point to the existence of several elliptical galaxies surrounded by very little dark matter as evidence that dark matter is not, in fact, the cause of the warped galaxies. While they do not claim that their findings should be interpreted to conclude that dark matter does not exist, they apparently believe that the results of their studies cast doubt on some of the conventional theories of galaxy formation and manipulation.
Several models constructed by researchers from the University of California at Berkeley, however, point to the idea that dark matter is the most likely explanation for the distorted shape of the Milky Way and other galaxies. Using computer models, they have mapped the likely interactions between certain galaxies and the surrounding dark matter, and those models have shown not only the possibility that dark matter is responsible for the warped shape of the Milky Way, but that the relationship between the dark matter and the Magellanic clouds is dynamic; the movement of the clouds through the dark matter seems to create a wake that enhances their gravitational influence on the Milky Way.

In ancient Greece, athletic festivals were very important and had strong religious associations. The Olympic athletic festival, held every four years in honour of Zeus, eventually lost its local character, became first a national event, and then, after the rules against foreign competitors had been abolished, international. No one knows exactly how far back the Olympic Games go, but some official records date from 776 B.C.
The Games took place in August on the plain by Mount Olympus. Many thousands of spectators gathered from all parts of Greece, but no married woman was admitted even as a spectator. Slaves, women and dishonoured people were not allowed to compete. Records show that the evening of the third day was devoted to sacrificial offerings to the heroes of the day, and the fourth day, that of the full moon, was set aside as a holy day. On the sixth and last day all the victors were crowned with holy garlands of wild olive from a sacred wood. So great was the honour that the winner of the foot race gave his name to the year of his victory. How their results compared with modern standards, we unfortunately had no means of telling.
After an uninterrupted history of almost 1,200 years, the Games were abolished in A. D. 394 because of their pagan origin. It was a great many years before there was another such international athletic gathering. The Greek institution was brought back into existence in 1896 and the first small meeting took place in Athens. After the 1908 London Olympics, success was re-established and nations sent their best representatives.
Today, the Games are held in different countries in turn. The host country provides vast facilities, including a stadium, swimming pools and living accommodation, but competing countries pay their own athletes' expenses. Athletic contests are still the main feature, but now many more sports are represented, women compete, the ancient pentathlon, for example, has been modified into a more comprehensive test, and the marathonraces, initiated in 1896, are now a celebrated event.
The Olympics start with the arrival in the stadium of a torch, lighted on Mount Olympus by the sun's rays. It is carried by a succession of runners to the stadium. The torch symbolizes the continuation of the ancient Greek athletic ideals, and it burns throughout the Games until the closing ceremony.
