At the beginning of the nineteenth century, the American educational system was desperately in need of reform. Private schools existed, but only for the very rich. There were very
few public schools because of the strong sentiment that children who would grow up to be laborers should not “waste” their time on education but should instead prepare themselves for their life’s work. It was in the face of this public sentiment that educational reformers set about their task. Horace Mann, probably the most famous of the reformers, felt that there was no excuse in a republic for any citizen to be uneducated. As Manager of Education in the state of Massachusetts from 1837 to 1848, he initiated various changes, which were soon matched in other school districts around the country. He extended the school year from five to six months and improved the quality of teachers by instituting teacher education and raising teacher salaries. Although these changes did not bring about a sudden improvement in the educational system, they at least increased public awareness as to the need for a further strengthening of the system.

We find that bright children are rarely held back by mixed- ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed- ability teaching contributes to all these aspects of learning. In our classrooms, we work in various ways. The pupils often work in groups; this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teachers. Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments; and they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them the skills they need in order to do this effectively. An advanced pupil can do advanced work; it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.

Read the following passage and choose the best answer (A, B, C, D):
Like the revolutions that preceded it, the Fourth Industrial Revolution has the potential to raise global income levels and improve the quality of life for populations around the world. To date, those who have gained the most from it have been consumers able to afford and access the digital world; technology has made possible new products and services that increase the efficiency and pleasure of our personal lives. Ordering a cab, booking a flight, buying a product, making a payment, listening to music, watching a film or playing a game — any of these can now be done remotely. In the future, technological innovation will also lead to a supply-side miracle, with long-term gains in efficiency and productivity. Transportation and communication costs will drop, logistics and global supply chains will become more effective and the cost of trade will diminish, all of which will open new markets and drive economic growth. At the same time, as the economists Erik Brynjolfsson and Andrew McAfee have pointed out, the revolution could yield greater inequality, particularly in its potential to disrupt labor markets. As automation substitutes for labor across the entire economy, the net displacement of workers by machines might exacerbate the gap between returns to capital  and returns to labor. On the other hand, it is also possible that the displacement of workers by technology will, in aggregate, result in a net increase in safe and rewarding jobs. We cannot foresee at this point which scenario is likely to emerge, and history suggests that the outcome is likely to be some combination of the two. However, I am convinced of one thing — that in the future, talent, more than capital, will represent the critical factor of production. This will give rise to a job market increasingly segregated into “low-skill/low-pay” and “highskill/high-pay” segments, which in turn will lead to an increase in social tensions. In addition to being a key economic concern, inequality represents the greatest societal concern associated with the Fourth Industrial Revolution. The largest beneficiaries of innovation tend to be the providers of intellectual and physical capital — the innovators, shareholders and investors — which explains the rising gap in wealth between those dependent on capital versus labor. Technology is therefore one of the main reasons why incomes have stagnated, or even decreased, for a majority of the population in high-income countries: the demand for highly skilled workers has increased while the demand for workers with less education and lower skills has decreased. The result is a job market with a strong demand at the high and low ends, but a hollowing out of the middle. This helps explain why so many workers are disillusioned and fearful that their own real incomes and those of their children will continue to stagnate. It also helps explain why middle classes around the world are increasingly experiencing a pervasive sense of dissatisfaction and unfairness. A winnertakes-all economy that offers only limited access to the middle class is a recipe for democratic malaise and dereliction.

Preschool offers many benefits. It can be a great place for kids to interact with peers and learn valuable life lessons such as how to share, take turns, and follow rules. But going to preschool does come with some emotions, for both the parent and the child. For a child, entering a new preschool environment (1) ___________ with unfamiliar teachers and kids can cause both anxiety and excitement. Parents might have mixed emotions about (2) ___________ their child is ready for preschool. When you enter the classroom on the first day, calmly reintroduce the teacher to your child, then step back to allow the teacher to begin (3) __________ a relationship with your child. Your endorsement of the teacher will show your child that he or she will be happy and safe in the teacher’s care. If your child clings to you or refuses to participate in the class, don’t get upset — this may only upset your child more. Always say a loving goodbye to your child, but once you do, leave (4)________. Don’t sneak out. Leaving without saying goodbye can make kids feel abandoned. A long farewell, on the other hand, might only reinforce a child’s sense that preschool is a bad place. A consistent and predictable farewell routine can make leaving easier. Some parents wave from outside the classroom window or make a funny goodbye face, while others have a special handshake before parting. Transitional objects — a family picture, a special doll, or a favorite blanket — can also help comfort a child. Also, (5)___________ in mind that most kids do well after their parents leave

Alexander Hamilton was born on January 11, 1755 or 1757 in the West Indies. Due to his mother’s lack of marital status, Hamilton was not seen as a legitimate child and was thus denied access to church schools. When his mother died he was adopted by a merchant in Nevis, where he worked as a clerk. During his time in Nevis, Hamilton continued to write; one of his essays impressed the community leaders so much that they worked together and collected funds to send Hamilton to the colonies. Hamilton served in the revolutionary war, during which time he worked his way through battles and earned himself a place aiding General Washington. After the war, Hamilton was elected into the Congress of the Confederation. He was dissatisfied with the decentralized government that was set up and the inability to raise money from the states to pay the soldiers. Hamilton was involved in the Constitution Convention but did not fully agree with the document; despite his disagreements, he promoted the document because he believed it was a vast improvement over the Articles of Confederation. He pushed the ratification of the Constitution, teaming up with John Jay and James Madison to write the Federalist papers, which were often cited when pushing for the Constitution’s ratification. Alexander Hamilton was appointed as the country’s first Secretary of The Treasury on September 11, 1789. During his time as Secretary of the Treasury Hamilton helped write economic policies, develop the funding of state debts, establish the national bank, create a national currency, a system of tariffs, and a peaceful trade relationship with Britain. After his time in politics finished, Alexander Hamilton went back to New York to practice law. He died in a duel with Aaron Burr in Weehawken, New Jersey on July 12, 1804

Read the following passage and choose the best answer (A, B, C, D):
Egypt’s 100 millionth citizen was born last week, undoubtedly a happy occasion for one family, but a moment filled with foreboding for a country struggling to contain a population explosion. In the past year the government has scrambled to stem the birth rate with a new program called “Two is Enough.” It is establishing family planning clinics throughout the country, where Egyptians can purchase heavily subsidized contraceptives. But many doctors and activists fear that this is too little, and comes too late to reverse the uptick in population growth. Doctors complain that the new “Two is Enough” program lacks in a clear strategy to bring down birthrates. The financial resources deployed thus far have been a fraction of previous efforts; some family-planning clinics have reportedly run out of contraceptives. While clinics funded by the campaign to provide some reproductive health education, sexual education remains taboo in Egyptian schools. There is also a lack of adequate services for the poor and pensioners. Many Egyptians opt to have more children in the hope they will look after them as they age, a phenomenon common in countries with high levels of poverty and inadequate safety nets. While over 30 million Egyptians live in poverty, only 9.4 million receive means-tested cash transfers from the government’s welfare programs. Economic reforms undertaken as part of a recently completed International Monetary Fund program have cut subsidies in a number of areas, contributing a spike in inflation that at one point exceeded 30%. For newborns like the 100-millionth Egyptian, the outlook is grim. A burgeoning population exacerbates many problems. Despite Egypt’s limited supply - it depends almost exclusively on the Nile - there has been a systemic failure to adequately address water waste. From wasteful megaprojects draining the Nile to literally dumping waste in the river, Egyptian officials have consistently failed to prudently protect what is perhaps the country’s most vital natural resource. In 2018, Egypt temporarily reduced the farming of rice, a water intensive crop - only to expand cultivation the following year. The New Administrative Capital that Sisi has set out to erect is projected to need 650,000 cubic meters of water per day when finished. Failure to quickly and dramatically improve water management practices in Egypt could be disastrous, and the risk is the greater for the country’s rapid population growth

Light, litter and noise from boating and water sports are all major stressors on marine  life, a new study aims to enhance our knowledge of the effects of these stressors. Researchers will be gathering data from sporting events, leisure boating, tourism and beach activities. The project will assess the impact that these activities have on the environment and marine life in order to offer further guidance to organisers and water sports enthusiasts.  Mike Laflin said: “I’ve worked in the sports industry for 30 years, providing market intelligence and information services and a few years ago I started to measure the impact of sporting events on host cities and nations. I’m excited to support this new research so that we can understand more about how our activities impact the environment and how we can mitigate against any negative effects.” Theresa Laflin said: “We are very excited to be able to support all the wonderful work that the university is doing in the area of marine research, and for increasing our awareness of the detrimental impact we have on our environment.”  The PhD project will be supervised by Tamara Galloway, Professor of Ecotoxicology at Exeter, who conducts research into the human health effects of pollutants, particularly micro-plastics in water; and Steve Simpson, Associate Professor in Marine Biology and Global Change at the University of Exeter, who has shown that man-made noise is having a detrimental effect on the marine world. Simpson said: “Noise from offshore construction, shipping and motorboats all change the ocean soundscape, disrupting acoustic communication, robbing animals of fundamental sensory information and causing stress. However, working with industry we have found that by managing when and where noise is made, and developing new technology to reduce the noise, we can mitigate the impacts of noise. Finding solutions to reduce the impacts of sporting activities will further help to protect the marine environment.” Galloway said: “We’ll be looking at all forms of pollution both from everyday leisure activities and major sporting events. Investigating specific events gives us the opportunity to measure environmental quality before and after the event, and to return after a period of time to assess recovery. Such an event could be seen as an ‘acute stressor’. Then we’ll also assess ongoing sporting activities, akin to a ‘chronic stressor’ and will try to compare and contrast different types of impact.”

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Clara Barton became known as “The Angel of the Battlefield” during the American Civial War. Born in Oxford, Massachusetts in 1821, Clara Barton’s interest in helping soldiers on the battlefield began when she was told army stories from her father. Another event that influenced her decision to help soldiers was an accident her brother had. His injuries were cared for by Barton for 2 years. At the time, she was only 11 years old. Barton began teaching school at the age of 15. She taught for 18 years before she moved to Washington, D.C. in 1854.
The civil war broke out 6 years later. Immediately, Barton started was service by helping the soldiers with their needs. At the battle of Bull Run, Clara Barton received permission from the government to take care of the sick and hurt. Barton did this with great empathy and kindness. She acknowledged each soldier as a person. Her endurance and courage on the

battlefield were admired by many. When the war ended in 1865, she used 4 years of her life to assist the government in searching for soldiers who were missing during the war.
The search for missing soldiers and years of hard work made her feeble physically. In 1869, her doctors recommended a trip to Europe for a rest. While she was on vacation, she became involved with the International Red Cross, an organization set up by the Geneva Convention in 1864. Clara Barton realized that the red Cross would be a big help to the United States. After she returned to the United States, she worked very hard to create an American red Cross. She talked to government leaders and let American people know about the Red Cross. In 1881, the Notional Society of the Red Cross was finally established with its headquarters in Washington, D.C. Clara Barton managed its activities for 23 years.
Barton never let her age stop her from helping people. At the age of 79, she helped flood victims in Galveston, Texas. Barton finally resigned from the Red Cross in 1904. She was 92 years old and had truly earned her titled “The Angel of the Battlefield”.

Read the following passage and choose the best answer (A, B, C, D):
The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.
6. According to paragraph 3, what is NOT one of the changes the AM technologyintroduces to hospital?

The International Monetary Fund (IMF) is an organization of 189 member countries.  It stabilizes the global economy in three ways. First, it monitors global conditions and identifies risks. Second, it advises its members on how to improve their economies. Third, it provides technical assistance and short-term loans to prevent financial crises. The IMF’s goal is to prevent these disasters by guiding its members. These countries are willing to give up some of their sovereign authority to achieve that aim.  The IMF has the rare ability to look into and review the economies of all its member countries. As a result, it has its finger on the pulse of the global economy better than any other organization. The IMF produces a wealth of analytical reports. It provides the World Economic Outlook, the Global Financial Stability Report, and the Fiscal Monitor each year. It also delves into regional and country-specific assessments. It uses this information to determine which countries need to improve their policies. Hence, the IMF can identify which countries threaten global stability. The member countries have agreed to listen to the IMF’s recommendations because they want to improve their economies and remove these threats.  Since the Mexican peso crisis of 1994–95 and the Asian crisis of 1997–98, the IMF has taken a more active role to help countries prevent financial crises. It develops standards that its members should follow. For example, members agree to provide adequate foreign exchange reserves in good times. That helps them increase spending to boost their economies during recessions. The IMF reports on members countries’ observance of these standards. It also issues member country reports that investors use to make well-informed decisions. That improves the functioning of financial markets. The IMF also encourages sustained growth and high living standards, which is the best way to reduce members’ vulnerability to crises.  The IMF provides loans to help its members tackle balance of payments problems, stabilize their economies, and restore sustainable growth. Because the Fund lends money, it’s often confused with the World Bank. The World Bank lends money to developing countries for specific projects that will fight poverty. Unlike the World Bank and other development agencies, the IMF does not finance projects. Traditionally, most IMF borrowers were developing countries. They had limited access to international capital markets due to their economic difficulties. An IMF loan signals that a country’s economic policies are on the right track. That reassures investors and acts as a catalyst for attracting funds from other sources. All that shifted in 2010 when the Eurozone crisis prompted the IMF to provide short-term loans to bail out Greece. That was within the IMF’s charter because it prevented a global economic crisis.  The role of the IMF has increased since the onset of the 2008 global financial crisis. In fact, an IMF surveillance report warned about the economic crisis but was ignored. As a result, the IMF has been called upon more and more to provide global economic surveillance. It’s in the best position to do so because it requires members to subject their economic policies to IMF scrutiny. Member countries are also committed to pursuing policies that are conducive to reasonable price stability, and they agree to avoid manipulating exchange rates for unfair competitive advantage.

There is still no consensus about how the Neanderthals were driven to extinction,  leaving our Homo sapien ancestors without any competition. The disappearance of the native European Neanderthals is odd partly because their shorter, stockier bodies must have made them better able to withstand the colder temperatures that prevailed when their cousins from Africa entered Europe. With a smaller surface area the Neanderthal body would have been able to retain more heat. The once common assumption that the key was the inferior vocal abilities of the Neanderthal has since been disproved by research on the Neanderthal hyoid bone, located in the throat. The larger skull capacity and brain is another respect in which they do not seem to have been inferior.  It was once thought that proof of a superior intellect was to be found in the narrower Homo sapien stone tools known as “blades”, which were assumed to be more efficient than the broader “flakes” used by the Neanderthals. In a number of important respects, including durability, this idea has proved to be unfounded. However, the blades would have been more effective as tips for throwing spears whereas the stone flakes would have been limited to the kind of thrusting spears the Neanderthals are believed to have used. This could have combined with the greater agility of the Homo sapiens to give them a distinct advantage in hunting on open terrain. Crucial in this respect were the larger canals in the Homo sapien inner ear, providing a more acute sense of balance, in addition to the longer limbs and lighter build. The Neanderthal technique of hiding and lying in wait for passing animals ceased to be viable when the dense forests of Europe began to recede. After a period of co-existence with their cousins, the Neanderthals were slowly eradicated.
According to the passage, what is now believed about the stone tools used by the

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

Read the following passage and choose the best answer (A, B, C, D):
Alzheimer's disease impairs a person's ability to recall memories, both distant and as a few hours before. Although there is no yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs. Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiment do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.

Read the following passage and choose the best answer (A, B, C, D):
Deforestation is the clearing, destroying, or otherwise removal of trees through  deliberate, natural or accidental means. It can occur in any area densely populated by trees and other plant life, but the majority of it is currently happening in the Amazon rainforest. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.  Deforestation occurs for a number of reasons, including: farming, mostly cattle due to its quick turn around; and logging for materials and development. It has been happening for thousands of years, arguably since man began converting from hunter/gatherer to agricultural based societies, and required larger, unobstructed tracks of land to accommodate cattle, crops, and housing. It was only after the onset of the modern era that it became an epidemic.  One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat; not only do we lose those known to us, but also those unknown, potentially an even greater loss. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. The trees of the rainforest that provide shelter for some species also provide the canopy that regulates the temperature, a necessity for many others. Its removal through deforestation would allow a more drastic temperature variation from day to night, much like a desert, which could prove fatal for current inhabitants. In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Presently, the tropical rainforests of South America are responsible for 20% of Earth’s oxygen and they are disappearing at a rate of 4 hectares a decade. If these rates are not stopped and reversed, the consequences will become even more severe.  The trees also help control the level of water in the atmosphere by helping to regulate the water cycle. With fewer trees left, due to deforestation, there is less water in the air to be returned to the soil. In turn, this causes dryer soil and the inability to grow crops, an ironic twist when considered against the fact that 80% of deforestation comes from small-scale agriculture and cattle ranching.  Further effects of deforestation include soil erosion and coastal flooding. In addition to their previously mentioned roles, trees also function to retain water and topsoil, which provides the rich nutrients to sustain additional forest life. Without them, the soil erodes and washes away, causing farmers to move on and perpetuate the cycle. The barren land which is left behind in the wake of these unsustainable agricultural practices is then more susceptible to flooding, specifically in coastal regions. Coastal vegetation lessens the impact of waves and winds associated with a storm surge. Without this vegetation, coastal villages are susceptible to damaging floods.
2. The word “indigenous” in the first paragraph probably means _________
