Commentary from researchers in the College of Pharmacy at The University of Texas at Austin in the journal Science provide new findings in alcohol use disorder (AUD) research The article, “Compelled to drink: Why some cannot stop,” considers recent findings by researchers Siciliano et al. that discovered individual differences in the activity of neurons in a frontal cortex to brain stem circuit that predicts the later escalation of alcohol drinking to compulsive intake in a mouse model. “These researchers not only defined a new brain circuit involved in compulsive drinking, but showed individual differences at the level of electrical activity in the neurons that comprise this circuit,” Nixon said. “The individual differences in electrical activity predicted which mice would go on to drink compulsively after a binge-like drinking episode despite drinking the same amount of alcohol during that episode.” The research group previously found that this circuit is important for responses to aversive events, and they have now asked why aversive outcomes don’t deter everyone from drinking alcohol. These new findings point to a neurological explanation for why only some mice continue to drink alcohol even when it comes with negative consequences. “They found these differences in circuit activity before mice developed compulsive drinking behavior,” Mangieri said. “In other words, some mice had a biological predisposition that made them susceptible to developing alcohol drinking behaviors that are similar to humans with AUD.” The researchers said the work has important implications. It has potential as a biomarker of propensity to develop severe AUD based on electrical activity. Also, the discovery of this circuit’s role in compulsive drinking suggests that there may be novel pharmacological targets that could be identified and developed for the treatment of AUDs

Do you find the American education system to be confusing and different from the education system in your own country? Do you want to attend a university or a school in the USA? The American education system offers international students the most diverse set of options in the world. In fact, an international student who elects to take advantage of the American education system can pursue anything from nuclear science to film and dance. The possibilities are almost endless! The American education system requires that students complete 12 years of primary and secondary education prior to attending university or college. This may be accomplished either at public (or government-operated) schools, or at private schools. These 12 years of schooling (or their equivalent) may also be completed outside the USA, thus giving foreign students the opportunity to pursue the benefits of the American education system and obtain a quality American education. Perhaps one of the most impressive facts is the large number of presidents, prime ministers and leaders from other countries who have experienced the American education system and graduated from a university or school in the USA. In many fields and industries, the American education system offers the most cutting-edge, soughtafter programs at the world’s best schools. That is why graduating from an accredited American school and being exposed to the rigors of the American education system is an investment in your future. Whether you want to study at a USA university, a top college, or at an ESL, vocational or high school, a thorough understanding of how the American education system works is essential. Without a clear grasp of the system, an international student will find it difficult to make the right academic choices. The information provided in the Overview of the American education system section will help you develop that understanding. You can also search our list of Universities, colleges, community colleges, graduate schools, and boys and girls boarding schools. It is no surprise that the United States hosts more international students than any other country in the world!

Read the following passage and choose the best answer (A, B, C, D)
The greatest recent social changes have been in the lives of women. During the twentieth century there has been a remarkable shortening of the proportion of a woman’s life spent in caring for children. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, opportunity and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and can be expected to live another thirty-five years and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances and convenience food. This important change in women’s life-pattern has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity, and most of them took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school- leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards return to full-time or part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life, and with both husband and wife sharing more equally in providing the money, and running the home, according to their abilities and interests of each of them.

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.

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)

The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.

They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry.

The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.

Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.

“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

The word sophisticated in paragraph 4 is closest in meaning to ____.

Read the following passage and choose the best answer (A, B, C, D):
Esperanto is what is called a planned, or artifiial, language. It was created more than a century ago by Polish eye doctor Ludwik Lazar Zamenhof. Zamenhof believed that a common language would help to alleviate some of the misunderstandings among cultures. In Zamenhof's fist attempt at a universal language, he tried to create a language that was as uncomplicated as possible. This fist language included words such as ab, ac, ba, eb, be, and ce.This did not result in a workable language in that these monosyllabic words, though short, were not easy to understand or to retain. Next, Zamenhof tried a different way of constructing a simplified language. He made the words in his language sound like words that people already knew, but he simplifid the grammar tremendously. One example of how he simplifid the language can be seen in the suffies: all nouns in this language end in o, as in the noun amiko, which means "friend", and all adjectives end in -a, as in the adjective bela, which means "pretty". Another example of the simplifid language can be seen in the prefi mal-, which makes a word opposite in meaning;theword malamiko therefore means "enemy", and the word "malbela" therefore means "ugly" in Zamenhof's language. In 1887, Zamenhof wrote a description of this language and published it. He used a pen name, Dr. Esperanto, when signing the book. He selected the name Esperanto because this word means "a person who hopes" in his language. Esperanto clubs began popping up throughout Europe, and by 1950, Esperanto had spread from Europe to America and Asia. In 1905, the First World Congress of Esperanto took place in France, with approximately 700 attendees from 20 different countries. Congresses were held annually for nine years, and 4,000 attendees were registered for the Tenth World Esperanto Congress scheduled for 1914, when World War I erupted and forced its cancellation. Esperanto has had its ups and downs in the period since World War I. Today, years after it was introduced, it is estimated that perhaps a quarter of a million people are flent in it. This may seem like a large number, but it is really quite small when compared with the billion English speakers and billion Mandarin Chinese speakers in in today's world. Current advocates would like to see its use grow considerably and are taking  steps to try to make this happen.

Body postures and movements are frequently indicators of self-confidence, energy, fatigue, or status. Cognitively, gestures operate to clarify, contradict, or replace verbal messages. Gestures also serve an important function with regard to regulating the flow of conversation. For example, if a student is talking about something in front of the class, single nods of the head from the teacher will likely cause that student to continue and perhaps more elaborate. Postures as well as gestures are used to indicate attitudes, status, affective moods, approval, deception, warmth, arid other variables related to conversation interaction.
The saying “A picture is worth a thousand words” well describes the meaning of facial expressions. Facial appearance – including wrinkles, muscle tone, skin coloration, and eye color- offers enduring cues that reveal information about age, sex, race, ethnic origin, and status.
A less permanent second set of facial cues-including length of hair, hairstyle, cleanliness, and facial hair-relate to an individual’s idea of beauty. A third group of facial markers are momentary expressions that signal that cause changes in the forehead, eyebrows, eyelids, cheeks, nose, lips, and chin, such as raising the eyebrows, wrinkling the brow, curling the lip.
Some facial expressions are readily visible, while others are fleeting. Both types can positively or negatively reinforce the spoken words and convey cues concerning emotions and attitudes.

The United States has had approximately a thousand lights as well as light towers,  range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Most of the lights in the United States have been built and maintained by the Coast Guard. As navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership to other parties. The first navigational lights in the New World were probably lanterns hung at harbor entrances. The first lighthouse was put up by the Massachusetts Bay Colony In 1766 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by light dues levied on ships, the original beacon was blown up in 1776. By then there were only a dozen or so true lighthouses in the colonies. Little over a century later, there were 700 lighthouses.  The first eight erected on the West Coast in the 1850’s featured the same basic New England design: a Cape Cod dwelling with the tower rising from the center or standing close by. In New England and elsewhere, though, lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were built on rocky eminences, enormous towers were not the rule. Some were made of stone and brick, others of wood or metal. Some stood on pilings or stilts: some were fastened to rock with iron rods. Farther south, from Maryland through the Florida Keys, the coast was low and sandy. It was often necessary to build tall towers there - massive structures like the majestic Cape Hatteras, North Carolina lighthouse, which was lit in 1870. At 190 feet, it is the tallest brick lighthouse in the country. Notwithstanding differences in appearance and construction, most American lighthouses shared several features: a light, living quarters, and sometimes a bell (or, later, a foghorn). They also had something else in common: a keeper and, usually, the keeper’s family. The keeper’s essential task was trimming the lantern Nick in order to maintain a steady bright flame. The earliest keepers came from every walk of life-they were seamen. Farmers, mechanics, rough mill hands-and appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouses was taken over in 1852 by the United States Lighthouse 803rd, an agency of the Treasury Department, the keeper corps gradually became highly professional.  
6. It can be inferred from the passage that the Treasury Department, after assuming control of the lighthouses, improved which of the following?

Nature photographer Joel Sartore is passionate about endangered species. He uses his  camera to make people aware of environmental problems. They tell the stories of animals that may disappear unless we work fast to save them.  Sartore’s latest project is called Photo Ark. The goal of the project is to make a photographic record of the world’s biodiversity. As Sartore says, “For many of Earth’s creatures, time is running out.”  When asked how he became interested in saving endangered species, Joel said “When I was a child, I read about Martha, the very last passenger pigeon. Martha died in 1914. I was shocked. In the past, there were 5 billion passenger pigeons – probably more than any other bird. But here was the last one, and there was no way to save it. How did we let this happen? I couldn’t understand it. I still feel the same way. I want to prevent this from ever happening again.” Photography is the best way to show problems to the world. It gets people to care about the problem. It’s not enough to just show pretty animals in a beautiful landscape. Now, we must show the threats to these animals as well. The good news is that there are many ways to publish stories and photographs on environmental issues. Self-publishing on the Web is one way to do this. Even nonprofessional photographers can help to make us aware of these problems

Scientists have uncovered a new threat to the world’s endangered coral reefs. They  have found that most are incapable of growing quickly enough to compensate for rising sea levels triggered by global warming. The study suggests that reefs – which are already suffering serious degradation because the world’s seas are warming and becoming more acidic – could also become overwhelmed by rising oceans.  The research – led by scientists at Exeter University and published in Nature this week – involved studying growth rates for more than 200 tropical western Atlantic and Indian Ocean reefs. It was found only 9% of these reefs had the ability to keep up with even the most optimistic rates of sea-level rises forecast by the Intergovernmental Panel on Climate Change. “For many reefs across the Caribbean and Indian Ocean regions, where the study focused, rates of growth are slowing due to coral reef degradation,” said Professor Chris Perry, of Exeter University. “Meanwhile, rates of sea-level rise are increasing – and our results suggest reefs will be unable to keep up. As a result, water depths above most reefs will increase rapidly through this century.”  Sea levels rose by several inches over the past century and measurements indicate the speed of this increase is now rising significantly. Two key factors are involved: climate change is making ocean water warmer and so it expands. And as ice sheets and glaciers melt, they increase amounts of water in the oceans.  At the same time, reefs are being weakened by ocean warming and also by ocean acidification, triggered as the seas absorb more and more carbon dioxide. These effects lead to bleaching events that kill off vast stretches of coral and limits their ability to grow.  “Our predictions, even under the best case scenarios, suggest that by 2100, the inundation of reefs will expose coastal communities to significant threats of shoreline change,” said co-author Prof Peter Mumby of Queensland University. This point was backed by US marine scientist Ilsa Kuffner writing in a separate comment piece for Nature. “The implications of the study are dire. Many island nations and territories are set to quickly lose crucial natural resources.”

War: very bad for humanity, good for heavy metal. And cult Swedish rockers Sabaton are the best of the best when it comes to militaristic concept albums Iron Maiden’s ‘The Trooper’. Black Sabbath’s ‘War Pigs’. ‘One’ by Metallica. ‘Angel Of Death’ by Slayer. It’s quite the playlist. And yet it’s unlikely that anyone will ever rival Swedish power metallers Sabaton for their commitment to writing songs about humans shooting each other and blowing stuff up. Sabaton, it should be made clear, are a band who are named after a piece of armour worn on a medieval knight’s foot. The Swedes’ fourth album, 2008’s seminal ‘The Art Of War’, was a concept album based on the writings of the ancient Chinese military strategist Sun Tzu. And, on stage, they normally perform in front of a tank. This time round the theme is the First World War. It arrives 20 years since the band formed. If you’re a fan of this stuff – powerful, bruising, operatic, performed with absolutely no sense of irony whatsoever – then there’s no question that Sabaton are amongst the best of the best. ‘Fields Of Verdun’ gallops into a colossal hook that’s only superseded by the song’s killer chorus. Opener ‘The Future Of Warfare’ sees singer Joakim Brodén’s vocals building a path skyward, “while” Devil Dogs rampages like Iron Maiden did when punk was still part of their repertoire. This is the album that could take Sabaton upwards. The subject matter might be heavy, but Sabaton deserve credit for managing to deliver often difficult themes in a way that still manage to be fun – a quality the genre they exist within has lost sight of in recent times – while also maintaining some respect for the fallen

Read the following passage and choose the best answer (A, B, C, D):
Automated manufacture arose out of the intimate relationship of such economic forces and technical innovations as the division of labor, power transfer and the mechanization of the factory, and the development of transfer machines and feedback systems as explained below. The division of labor (that is, the reduction of a manufacturing or service process into its smallest independent steps) developed in the latter half of the 18th century and was first discussed by the Scottish economist Adam Smith in his book An Inquiry into the Nature and Causes of the Wealth of Nations (1776). In manufacturing, the division of labor results in increased production and a reduction in the level of skills required of workers. Mechanization was the next step necessary in the development of automation. The simplification of work made possible by the division of labor also made it possible to design and build machines that duplicated the motions of the worker. As the technology of power transfer evolved, these specialized machines were motorized and their production efficiency was improved. The development of power technology also gave rise to the factory system of production, because all workers and machines had to be located near the power source. The transfer machine is a device used to move a workpiece from one specialized machine tool to another, in such a manner as to properly position the workpiece for the next machining operation. Industrial robots, originally designed only to perform simple tasks in environments dangerous to human workers, are now extremely dexterous and are being used to transfer, handle, and index (that is, to position) both light and heavy workpieces, thus performing all the functions of a transfer machine. In actual practice, a number of separate machines are integrated into what may be thought of as one large machine. In the 1920s the auto industry combined these concepts into an integrated system of production. The goal of this assembly-line system was to make automobiles available to people who previously could not afford them. This method of production was adopted by most automobile manufacturers and rapidly became known as Detroit automation. Despite more recent advances, it is this system of production that most people think of as automation.
