Read the following passage and choose the best answer (A, B, C, D):
Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.

Read the following passage and choose the best answer (A, B, C, D):
For nearly all of human history, there haven’t been that many of us. Around the year zero, Earth’s population is estimated to have been 190 million. A thousand years later, it was probably around 250 million. Then the Industrial Revolution happened, and human population went into overdrive. It took hundreds of thousands of years for humans to hit the 1 billion mark, in 1800. We added the next billion by 1928. In 1960, we hit 3 billion. In 1975, 4 billion. That sounds like the route to an overpopulation apocalypse, right? To many midcentury demographers, futurists, and science fiction writers, it certainly predicted one. Extending the timeline, they saw a nightmarish future ahead for humanity: human civilizations constantly on the brink of starvation, desperately crowded under horrendous conditions, draconian population control laws imposed worldwide. Stanford biologist Paul Ehrlich wrote in his best-selling book, “In the 1970’s, hundreds of millions of people will starve to death” because of overpopulation. None of that ever came to pass. The world we live in now, despite approaching a population of nearly 8 billion, looks almost nothing like the one doomsayers were anticipating. Starting in the 19th century in Britain and reaching most of the world by the end of the 20th century, birthrates plummeted — mostly because of women’s education and access to contraception, not draconian population laws. In wealthy societies where women have opportunities outside the home, the average family size is small; in fact, it’s below replacement level. Called the demographic transition, it is one of the most important phenomena for understanding trends in global development. There’s still significant debate among population researchers about the extent of the sea change in population trends. Researchers disagree on whether global populations are currently on track to start declining by midcentury. There’s also disagreement on what the ideal global population figure would be, or whether it’s morally acceptable to aim for such a figure. While academic research seeks to nail down these questions, it’s important to be clear what is consensus among researchers. Our projections around population are used to make global health and development policy. They’re critical for planning, especially about climate change. Fears of overpopulation sometimes turn into hostility to immigrants, those who choose to have large families, and countries in an earlier stage of their population transition. Having an informed conversation about population is crucial if we are to get humanity’s future right.

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.

Read the following passage and choose the best answer (A, B, C, D):
Whether a species is endangered—meaning at risk of extinction—depends on which definition you use. The International Union for Conservation of Nature’s Red List of Threatened Species classifies an animal as endangered when its numbers in the wild have dropped so low that it’s at “extremely high risk” of extinction. Meanwhile, the United States’ Endangered Species Act of 1973 takes into consideration any destruction to a species’ habitat, whether it has been over-consumed, any disease or predation that threaten it, whether any other man-made factors put it in danger, and what policies currently exist to protect it. When members of the public or a state agency propose to the U.S. Fish & Wildlife Service or the National Marine Fisheries Service that a species be listed as endangered under the law, research and management plans are formed to help those species survive. It is illegal under the Endangered Species Act to capture, hunt, shoot, or otherwise harm an animal that’s listed as endangered. Sometimes, federal agencies decide that although a species could be considered endangered, other species are higher priorities. In those cases, the animal or plant gets limited protections. One animal whose numbers have increased through conservation is the bald eagle. There were only about 500 bald eagles in the continental United States in the 1960s because of pesticides that damaged the shells of their eggs. Conservation efforts including captive breeding programs, habitat protection, and a ban on the insecticide DDT helped the bald eagle’s numbers soar back into the thousands. Another is the giant panda, which was declared no longer endangered in 2016 thanks to 50 years of efforts to save it. U.S. Rep. John Dingell, who wrote the Endangered Species Act, argued that “only natural extinction is part of natural order.” Scientists believe that 227 species - including the grizzly bear, the peregrine falcon and the gray wolf - were saved from extinction in the first 33 years of the law’s existence. Still, critics argue that the act is expensive and ineffective because it protects so many species. Several federal courts have heard and rejected arguments that the Endangered Species Act is unconstitutional, and members of Congress have tried to weaken the law in small ways.

Read the following passage and choose the best answer (A, B, C, D):
Rains that are almost biblical, heat waves that don’t end - there’s been a change in the weather lately. What’s going on? Extreme weather is an unusual weather event such as rainfall, a drought or a heat wave in the wrong place or at the wrong time. In theory, they are very rare. But these days, our TV screens are constantly showing such extreme weather events. Take just three news stories from 2010: 28 centimetres of rain fell on Rio de Janeiro in 24 hours, Nashville, USA, had 33 centimetres of rain in two days and there was record rainfall in Pakistan. The effects of this kind of rainfall are dramatic and lethal. In Rio de Janeiro, landslides followed, burying hundreds of people. In Pakistan, the floods affected 20 million people. Meanwhile, other parts of the world suffer devastating droughts. Australia, Russia and East Africa have been hit in the last ten years. And then there are unexpected heat waves, such as in 2003 in Europe. That summer, 35,000 deaths were said to be heat-related. Peter Miller, a National Geographic columnist, says what is happening to our weather is probably a mixture of numerous factors. On the one hand, the most important influences on weather events are natural cycles in the climate. Two of the most famous weather cycles, EI Nino and La Nina, originate in the Pacific Ocean. The heat from the warm ocean rises high into the atmosphere and affects weather all around the world. On the other hand, the temperature of the Earth’s oceans is slowly but steadily going up. And this is a result of human activity. We are producing greenhouse gases that trap heat in the Earth’s atmosphere. This heat warms up the atmosphere, land and oceans. Warmer oceans produce more water vapour - think of heating a pan of water in your kitchen. Turn up the heat, it produces steam more quickly. Satellite data tells us that the water vapour in the atmosphere has gone up by four percent in 25 years. This warm, wet air turns into the rain, storms, hurricanes and typhoons that we are increasingly experiencing. Climate scientist, Michael Oppenheimer, says that we need to face the reality of climate change. And we also need to act now to save lives and money in the future

Read the following passage and choose the best answer (A, B, C, D):
Set aside time each day Most of us can find 15 minutes or half an hour each day for some specific regular activity. It may be a free period or a regular wait, stay in the queue for a bus or meal - even while eating breakfast. One famous surgeon always made it a rule to spend at least 15 minutes on general reading before he went to sleep each night. Whether he went to bed at 10:00 p.m or 2:30 a.m. made no difference. Even if you cannot keep to this kind of discipline, it is a good idea to make sure you always have a general interest book in your pocket. Don’t forget it should be a book which entertains you and the English must not be too difficult for you. Checking your progress through pacing Nearly all speed reading courses have a "pacing element - some timing device which lets the student know how many words a minute he is reading. You can do this simply by looking at your watch every 5 or 10 minutes and noting down the page number you have reached. How do you know when 5 minutes have passed on your watch if you are busy reading the book? Well, this is difficult at first. A friend can help by timing you over a set period. Pace yourself every three or four days, always with the same kind of easy, general interest book. You should soon notice your habitual w. p. m rate creeping up. Check comprehension Obviously there is little point in increasing your w. p. m rate if you do not understand what you are reading. When you are consciously trying to increase your reading speed, stop after every chapter (if you are reading a novel) or every section or group of ten or twelve pages (if it is a textbook) and ask yourself a few questions about what you have been reading. If you find you have lost the thread of the story, or you cannot remember clearly the details of what was said, re-read the section or chapter. “Lightening speed” exercise Take 4 or 5 pages in the general interest book you happen to be reading at the time. Read them as fast as you possibly can. Do not bother about whether you understand or not. Now go back and read them at what you feel to be your normal w. p. m rate, the rate at which you can comfortably understand. After a “lightening speed” read through (probably around 6 w. p. m) you will usually find that your normal speed has increased - perhaps by as much as 50 -100 w. p. m.

Read the following passage and choose the best answer (A, B, C, D):
Learning shouldn’t end when you reach a certain point in your career; it should be something you continuously pursue across your lifetime. As you mature, your areas of interest may change. Perhaps your personal and career goals may morph into something altogether different than what you originally intended. In some cases, life happens and you might find it necessary to take a break from your career or your education. But for people with a strong desire for lifelong learning, this pause is only temporary. Even though you may have begun an educational program and needed to take a pause later, it’s never too late to go back and finish what you started. People in modern age have more options to gain the knowledge they want and need. From a higher education standpoint, universities and colleges are working hard to transform themselves in different ways. For example, there has been a transition from traditional Ph.D.-style doctorates to applied doctorates like the Doctorate in Strategic Intelligence or Doctorate in Global Security. These academic programs have their students work to address real-world problems of practice. In this manner, they take the education they receive in their classes and work to apply it within the fields in which they are currently employed or hope to work in. In addition, some universities now offer dual degree programs, such as the dual master’s degree in emergency and disaster management and homeland security. Some institutions are also starting to provide accelerated degrees to allow their students to rapidly advance from a B.A. to an M.A., saving those students time and money on their educational pursuits. However, lifelong learning doesn’t just encompass full degree programs. With employers focusing on skillset development, there is an increasing desire for short program offerings as well. “Short programming” includes sets of courses that lead to a specific credential or badge. For instance, ASIS International offers a series of certifications, related to security and global studies, which can be used to add value to your professional portfolio. Another relevant certification is the Certified Threat Manager (CTM) certification offered by the Association of Threat Assessment Professionals. Short programming involves learning tracks, competency-based micro-credentials or stackable credentials. In some cases, certificates are perceived to be more valuable as they signal that their owner has current knowledge of a particular area; however, this perception differs from field to field

In the past, technology and progress was very slow. People “invented” farming 12,000 years ago but it took 8,000 years for the idea to go around the world. Then, about 3,500 years ago, people called “potters” used round wheels to turn and make plates. But it took hundreds of years before some clever person thought, if we join two wheels together and make them bigger, we can use them to move things. In the last few centuries, things have begun to move faster. Take a 20th-century invention like the aeroplane, for example. The first aeroplane flight on 17 December 1903 only lasted 12 seconds, and the plane only went 37 metres. It can’t have been very exciting to watch, but that flight changed the world. Sixteen years later, the first plane flew across the Atlantic, and only fifty years after that, men walked on the moon. Technology is now changing our world faster and faster. So what will the future bring? One of the first changes will be the materials we use. Scientists have just invented an amazing new material called grapheme, and soon we will use it to do lots of things. With grapheme batteries in your mobile, it will take a few seconds to charge your phone or download a thousand gigabytes of information! Today, we make most products in factories, but in the future, scientists will invent living materials. Then we won’t make things like cars and furniture in factories - we will grow them! Thirty years ago, people couldn’t have imagined social media like Twitter and Facebook. Now we can’t live without them. But this is only the start. Right now, scientists are putting microchips in some disabled people’s brains, to help them see, hear and communicate better. In the future, we may all use these technologies. We won’t need smartphones to use social media or search the internet because the internet will be in our heads! More people will go into space in the future, too. Space tourism has already begun, and a hundred years from now, there may be many hotels in space. One day, we may get most of our energy from space too. In 1941, the writer Isaac Asimov wrote about a solar power station in space. People laughed at his idea then, but we should have listened to him. Today, many people are trying to develop a space solar power station. After all, the sun always shines above the clouds!

If parents bring up a child with the sole aim of turning the child into a genius, they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes which ambitious parents make. Generally, the child will be only too aware of what his parents expect, and will fail. Unrealistic parental expectations can cause great damage to children.
However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child. Michael Collins is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers twice a week for violin lessons. Michael's mother knows very little about music, but his father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling.
Winston Smith, Michael's friend, however, is not so lucky. Both his parents are successful musicians, and they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.Who have criticized the methods of some ambitious parents?

With exams approaching, you should be thinking about how to get better at time management and organize your days so you can strike the right balance between home, work and university life. You should also try and eat some brain food - and no, we don’t mean crisps and energy drinks! By taking the time to arrange your priorities, you can give yourself the best chance of staying on track and being organized during the exam period, which in turn can help reduce stress levels, something that can be the difference between success and failure at university. Take a look at our top time management tips, so that you can do your best at university and also find moments to relax and even earn some money on the side. First and foremost, allow time for planning to avoid repetition. Taking the time to research, plan and think about your work is crucial for good time management. Allow yourself the time to process new information and plan how you are going to use it, as this can help you to avoid having to re-read and repeat any research. One way of effectively planning before researching is to make a list of everything you want to find out, so that you can make notes below each subheading as you go Secondly, avoid procrastination and distraction. One way to avoid procrastination is to think about the different places you have been when studying - where were you the most focused? Where were you most distracted? Is there anything you can do to make studying actually somewhat enjoyable? Remember, what works for one person might not necessarily work for you. For some, studying with friends can limit their productivity. But for others, studying in groups can help to increase motivation and avoid procrastination. Next, exercise to clear your head in between study sessions. Believe it or not, exercise works in the same way sleep does. It can focus your state of mind, helping you to clear your head and boost your brain power in between study sessions. If you’re new to exercise, aim to fit in a 10-minute run here and there, steadily increasing the amount you do as you go on. Finally, ask yourself the question, “Has your organization been effective?” Constantly reviewing and reassessing your schedule can help you to recognize whether you need to make any changes in order to help you complete any university tasks and also have time to relax and spend time with friends and family.

There is a new type of advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it does not offer anyone a job, and sometimes it appears “situations wanted”, although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job. “Contact us before writing your application”, or "Make use of our long experience in preparing your curriculum vitae or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right. There was a time when job seekers simply wrote letters of application. “Just put down your name, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment, the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest. Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for,” was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job in view

If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the plants, without whose prior invasion of the land, none of the other migrations could have happened. Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches. There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of he dinosaurs, with
fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.

Music can bring us to tears or to our feet, drive us into battle or lull us to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that very reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia, even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet- sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system – an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For example, the fact that whale and human music have so much in common even though our evolutionary paths have not intersected for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene.
Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers – and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazing, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also berather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes – singing the new whales’ songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.
The underlined word “sophisticated” in paragraph 1 can be best replaced by .

Once restricted to luxury or super-tech buildings, home automation is proving to be an increasingly fundamental and affordable addition to architectural projects. The idea is to connect devices, which in turn connect and talk through a centralized control unit, accessible by computers, tablets, and mobile phones. For example, home automation users can turn the lights on or off at specific times each day, adjust the heater or air conditioner to turn on a few minutes before they arrive home. In addition to these immediate effects, monitoring applications can also provide accurate home information by generating detailed reports on equipment that could be working better or spending less. That is, in addition to smartphones and personal computers, appliances and sensors are able to identify patterns, process information, and perform tasks both through commands and automatically. Although it sounds like a science fiction script, these are technologies that are not so far from us. Artificial intelligence can be used to automate threat detection and perhaps more proactively alert us if something looks wrong, such as heat sensors and video cameras setting off alarms and calling firefighters in the event of a short circuit. Through facial recognition algorithms on social media, the system itself can tell if someone outside your circle of acquaintances is trying to access your space and send a message to your mobile phone. This type of technology can improve the efficiency of security systems and reduce false alarms. Automation can be useful for people with disabilities and for the elderly. People with Parkinson’s disease or other motor diseases can trigger switches without touching them, and motion sensors can trigger safety lights automatically. Blood pressure sensors and blood sugar levels can be incorporated into these systems, providing peace of mind to close relatives. The ability to automate repetitive housekeeping can free time for more important things. For example, an internet-connected refrigerator can check for missing items and make purchases online. It is important to mention that these systems must be highly protected, as a single attempt to break into this centralized system can lead to the invasion of privacy and the loss of valuable confidential information. Still, most people who have experienced life in an automated space will likely be uncomfortable returning to traditional systems
