CAN ANIMALS TALK?

In 1977, a young Harvard graduate named Irene Pepperberg brought a one-year-old African gray parrot into her lab, and attempted something very unusual. At a time when her fellow scientists thought that animals could only communicate on a very basic level, Irene set out to discover what was on a creature's mind by talking to it. The bird, named Alex, proved to be a very good pupil.

Scientists at the time believed that animals were incapable of any thought. They believed that animals only reacted to things because they were programmed by nature to react that way, not because they had the ability to think or feel. Any pet owner would probably disagree. Pepperberg disagreed, too, and started her work with Alex to prove them wrong.

Pepperberg bought Alex in a pet store. She let the store's assistant pick him out because she didn't want other scientists saying later that she'd deliberately chosen an especially smart bird for her work. Most researchers thought that Pepperberg's attempt to communicate with Alex would end in failure.

However, Pepperberg's experiment did not fail. In fact, over the next few years, Alex learned to imitate almost one hundred and fifty English words, and was even able to reason and use those words on a basic level to communicate. For example, when Alex was shown an object and was asked about its shape, color, or material, he could label it correctly. He could understand that a key was a key no matter what its size or color, and could figure out how the key was different from others.

Pepperberg was careful not to exaggerate Alex's success and abilities. She did not claim that Alex could actually “use” language. Instead, she said that Alex had learned to use a two-way communication code. Alex seemed to understand the turn-taking pattern of communication.

Which of the following is NOT true about Irene's parrot Alex?

Very few people in the modern world obtain their food supply by hunting and gathering in the natural environment surrounding their homes. This method of harvesting from nature’s provision is the oldest known subsistence strategy and has been practised for at least the last two million years. It was, indeed, the only way to obtain food until rudimentary farming and the domestication of wild animals were introduced about 10,000 years ago.
Because hunter-gatherers have fared poorly in comparison with their agricultural cousins, their numbers have dwindled, and they have been forced to live in marginal environments, such as deserts and arctic wastelands. In higher latitudes, the shorter growing seasons have restricted the availability of plant life. Such conditions have caused a greater dependence on hunting, and on fishing along the coasts and waterways. The abundance of vegetation in the lower latitudes of the tropics, on the other hand, has provided a greater opportunity for gathering a variety of plants. In short, the environmental differences have restricted the diet and have limited possibilities for the development of subsistence societies.
Contemporary hunter-gatherers may help us understand our prehistoric ancestors. We know from the observation of modern hunter-gatherers in both Africa and Alaska that a society based on hunting and gathering must be very mobile. While the entire community camps in a central location, a smaller party harvests the food within a reasonable distancefrom the camp. When the food in the area has become exhausted, the community moves on to exploit another site. We also notice seasonal migration patterns evolving for most hunter-gatherers, along with a strict division of labor between the sexes. These patterns of behavior may be similar to those practised by mankind during the Paleolithic Period.

The word ''marginal'' in the second paragraph is closest in meaning to"     ".

Plants and animals will find it difficult to escape from or adjust to the effect of global warming, Scientists have already observerd shifts in the lifecycles of many plants and animals, such as flowers blooming earlier and birds hatching earlier in the spring. Many species have begun shifting where they live or their annual migration patterns due to warmer temperatures.
With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations. Plants will also attempt to shift their ranges, seeking new areas as old habitats grow too warm. In many places, however, human development will prevent these shifts. Species that find cities or farmland blocking their way north or south may become extinct. Species living in unique ecosystems, such as those found in polar and mountantop regions, are especially at risk because migration to new habitats is not possible. For example, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther to go.
Projecting species extinction due to global warming is extremely difficult. Some scientists have estimated that 20 to 50 percent of species could be committed to extiction with 2 to 3 Celsius degrees of further warming. The rate of warming, not just the magnitude, is extremely important for plants and animals. Some species and even entire ecosystems, such as certain types of forest, many not be able to adjust quickly enough and may disappear.
Ocean ecosystems, especially fragile ones like coral reefs, will also be affected by global warming. Warmer ocean temperatures can cause coral to "bleach", a state which if prolonged will lead to the death of the coral. Scientists estimate that even 1 Celsius degree of additional warming could lead to widespread bleaching and death of coral reefs around the world. Also increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters. This acidification furter stresses ocean ecosystems.

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. 
More than 200 reindeer have died of starvation on the Norwegian archipelago of Svalbard, with scientists blaming their deaths on climate change. The wild deer carcasses were found on the Arctic islands this summer by researchers from the Norwegian Polar Institute (NPI), which said it had never logged so many deaths at once in 40 years of monitoring the animals’ population level. “It’s scary to find so many dead animals,” project leader Ashild Onvik Pedersen told state broadcaster NRK. “This is an example of how climate change affects nature. It is just sad.”
Svalbard’s capital Longyearbyen, the northernmost town on earth, is thought to be warming quicker than any other settlement on the planet, climate scientists warned earlier this year. The milder temperatures in the region led to unusually heavy rainfall in December, leaving a thick layer of ice when the precipitation froze. This meant the reindeer could not dig through the hardened tundra to reach the vegetation they graze on in their usual pastures, the NPI said. Svalbard’s reindeer have been observed eating seaweed and kelp when food is scarce, but these are less nutritious and cause them stomach problems.
A relatively high number of calves born last year increased the death toll, as the youngest and weakest are often the first to die in harsh conditions. “Some of the mortality is natural because there were so many calves last year. But the large number we see now is due to heavy rain, which is due to global warming,” said Ms Onvik Pedersen.
A team of three scientists spent 10 weeks investigating population of the Svalbard reindeer earlier this year. Researchers warned the decline of reindeer would cause unwanted plant species, currently kept in check by the animals’ grazing, to spread across Arctic ecosystems in Europe, Asia and North America.
Arctic reindeer and caribou populations have declined 56 per cent in the last two decades, a report by the National Oceanic and Atmospheric Administration said last year. The report said food security was partly to blame for falling herd numbers, while warmer summers could also put the animals at greater risk of diseases spread by flies and parasites. The average temperature in Longyearbyen has risen by 3.7C since 1900, more than three times the global average increase of about 1C. In 2016, the entrance to the town’s “Doomsday” seed vault – which stores specimens of almost all the world’s seeds – was flooded following heavy rainfall.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. 
     How might volunteering contribute to lower blood pressure? Performing volunteer work could increase physical activity among people who aren’t otherwise very active, says lead study author Rodlescia Sneed, a doctoral candidate in social and health psychology at Carnegie Mellon University. It may also reduce stress. “Many people find volunteer work to be helpful with respect to stress reduction, and we know that stress is very strongly linked to health outcomes,” she says.
     As with any activity thought to improve health, researchers are trying to identify the specific characteristics of volunteering that provide the greatest benefit. For example, how much time would you need to put into volunteer work to lower your blood pressure or live longer? In the Carnegie Mellon study, 200 hours of volunteering per year correlated to lower blood pressure. Other studies have found a health benefit from as little as 100 hours of volunteering a year. Which types of volunteer activities improve health the most? No one really knows. Sneed speculates that mentally stimulating activities, like tutoring or reading, might be helpful for maintaining memory and thinking skills, while “activities that promote physical activity would be helpful with respect to cardiovascular health, but no studies have really explored this.”
     One key for deriving health benefits from volunteering is to do it for the right reasons. A 2012 study in the journal Health Psychology found that participants who volunteered with some regularity lived longer, but only if their intentions were truly altruistic. In other words, they had to be volunteering to help others—not to make themselves feel better.
      The Greek philosopher Aristotle once surmised that the essence of life is “To serve others and do good.” If recent research is any indication, serving others might also be the essence of good health.

What does the passage mainly discuss?

Read the passage below and decide whether the statements are TRUE or FALSE?

   According to the Academic Ranking of World Universities, more than 30 of the highest-ranked 45 institutions are in the United States, as measured by awards and research output. Public universities, private universities, liberal arts colleges, and community colleges all have a significant role in higher education in the United States. An even stronger pattern is shown by the Webometrics Ranking of World Universities with 103 US universities in the World's Top 200 universities.

   The 2006 American Community Survey conducted by the United States Census Bureau found that 19.5 percent of the population had attended college but had no degree, 7.4 percent held an associate's degree, 17.1 percent held a bachelor's degree, and 9.9 percent held a graduate or professional degree.

   Educational attainment in the United States is similar to that of other developed countries. Colleges and universities in the U.S. vary in terms of goals: some may emphasize a vocational, business, engineering, or technical curriculum while others may emphasize a liberal arts curriculum. Many combine some or all of the above. Students can apply to some colleges using the Common Application. There is no limit to the number of colleges or universities to which a student may apply, though an application must be submitted for each.'

Read the following passage and choose among A, B, C or D the correct answer to each of the questions.

In my experience, freshmen today are different from those I knew when I started as a counselor and professor 25 years ago. College has always been demanding both academically and socially. But students now are less mature and often not ready for the responsibility of being in college.

It is really too easy to point the finger at parents who protect their children from life's obstacle. Parents, who handle every difficulty and every other responsibility for their children writing admission essays to picking college courses, certainly may contribute to their children's lack of coping strategies. But we can look even more broadly to the social trends of today.

How many people do you know who are on medication to prevent anxiety or depression? The number of students who arrive at college already medicated for unwanted emotions has increased dramatically in the past 10 years. We, as a society, don't want to "feel" anything unpleasant and we certainly don't want our children to "suffer".

The resulting problem is that by not experiencing negative emotions, one does not learn the necessary skills to tolerate and negotiate adversity. As a psychologist, I am well aware of the fact that some individuals suffer from depression and anxiety and can benefit from treatment, but I question the growing number of medicated adolescents today.

Our world is more stressful in general because of the current economic and political realities, but I don't believe that the college experience itself is more intense today than that of the past 10 years. What I do think is that many students are often not prepared to be young "adults" with all the responsibilities of life.

What does this mean for college faculty and staff? We are required to assist in the basic parenting of these students - the student who complains that the professor didn't remind her of the due date for an assignment that was clearly listed on the syllabus and the student who cheats on an assignment in spite of careful instructions about plagiarism.

As college professors, we have to explain what it means to be an independent college student before we can even begin to teach. As parents and teachers we should expect young people to meet challenges. To encourage them in this direction, we have to step back and let them fail and pick themselves up and move forward. This approach needs to begin at an early age so that college can actually be a passage to independent adulthood.

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 “How many hours does it take to make a friend?” (2018), Jeffrey A. Hall describes the types of encounters that build a friendship.
       His study found that hours of time spent together was linked with closer friendships, as was time spent enjoying leisure activities together. Specifically, he found that the chance of making a “casual friend,” as opposed to a mere acquaintance, was greater than 50 percent when people spent approximately 43 hours together within three weeks of meeting. He further found that casual friends evolve into friends at some point between 57 hours after three weeks, and 164 hours over three months. Hall's research also demonstrated, however, that when it comes to time spent developing friendships, quality is more important than quantity. And when it comes to conversation, topics matter. When it comes to building quality relationships, the duration of conversation is not as important as the content. Meaningful conversation is the key to bonding with others. 
       Hall found that when it comes to developing friendships, sharing daily life through catching up and joking around promotes closeness; small talk does not. Consider the inane topics that often come up when you are trapped in an elevator with an acquaintance. Discussing the weather or speculating on how many stops you will make before finally reaching the lobby does not facilitate bonding. Nor does mere proximity. Hall found that obligatory time spent together, such as in a classroom or workplace, does not promote closeness. Friendships require an efficient use of time together. Someone who remembers the details of your life and asks questions about your family, your job, your latest vacation, etc., is much more likely on his or her way to becoming someone you consider a friend, as opposed to an acquaintance.

According to paragraph 2, what conclusion can be drawn from the finding of Jeffrey A. Hall?

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

Successful students often do the following while studying. First, they have an overview before reading. Next, they look for important information and pay greater attention to it (which often needs jumping forward or backward to process information). They also relate important points to one another. Also, they activate and use their prior knowledge. When they realize that their understanding is not good, they do not wait to change strategies. Last, they can monitor understanding and take action to correct or "fix up" mistakes in comprehension.

Conversely students with low academic achievement often demonstrate ineffective study skills. They tend to assume a passive role in learning and rely on others (eg, teachers, parents) to monitor their studying, for example, low achieving students often do not monitor their understanding of content they may not be aware of the purpose of studying, and they show little evidence of looking back, or employing "fix-up strategies to fix understanding problems.

Students who struggle with learning new information seem to be unaware that they must extent effort beyond simply reading the content to understand and remember it. Children with learning disabilities do not plan and judge the quality of their studying. Their studying may be disorganized. Students with learning problems face challenges with personal organization as well. They often have difficulty keeping track of materials and assignments, following directions, and completing work on time. Unlike good studiers who employ a variety of study skills in a flexible yet purposeful manner, low-achieving students use a restricted range of study skills. They cannot explain why good study strategies are important for learning, and they tend to use the same, often ineffective study approach for all learning tasks, ignoring task content, structure or difficulty.

Choose the item among A, B, C or D that best answers the question about the passage: 

"Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have been near extinction. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300, and by the year 2025 their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this. extinction will have been caused almost entirely by poachers who, according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like the Bengal tiger, as well as other endangered species, are a valuable part of the world’s ecosystem. international laws protecting these animals must be enacted to ensure their survival, and the survival of our planet.
 Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then change admission to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. With the money they get, they can invest in equipment and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of Products made from endangered species. This seems fairly effective, but it will not, by itself, prevent animals from being hunted and killed."

       Although television was first regarded by many as “radio with pictures,” public reaction to the arrival of TV was strikingly different from that afforded the advent of radio. Radio in its early days was perceived as a technological wonder rather than a medium of cultural significance. The public quickly adjusted to radio broadcasting and either enjoyed its many programs or turned them off. Television, however, prompted a tendency to criticize and evaluate rather than a simple on-off response.
      One aspect of early television that can never be recaptured is the combined sense of astonishment and glamour that greeted the medium during its infancy. At the midpoint of the 20th century, the public was properly agog about being able to see and hear actual events that were happening across town or hundreds of miles away. Relatively few people had sets in their homes, but popular fascination with TV was so pronounced that crowds would gather on the sidewalks in front of stores that displayed a working television set or two. The same thing happened in the typical tavern, where a set behind the bar virtually guaranteed a full house. Sports events that might attract a crowd of 30,000 or 40,000 suddenly, with the addition of TV cameras, had audiences numbering in the millions. By the end of television’s first decade, it was widely believed to have greater influence on American culture than parents, schools, churches, and government-institutions that had been until then the dominant influences on popular conduct. All were superseded by this one cultural juggernaut.
       The 1950s was a time of remarkable achievement in television, but this was not the case for the entire medium. American viewers old enough to remember TV in the ’50s may fondly recall the shows of Sid Caesar, Jackie Gleason, Milton Berle, and Lucille Ball, but such high-quality programs were the exception; most of television during its formative years could be aptly described, as it was by one Broadway playwright, as “amateurs playing at home movies.” The underlying problem was not a shortage of talented writers, producers, and performers; there were plenty, but they were already busily involved on the Broadway stage and in vaudeville, radio, and motion pictures. Consequently, television drew chiefly on a talent pool of individuals who had not achieved success in the more popular media and on the young and inexperienced who were years from reaching their potential. Nevertheless, the new medium ultimately proved so fascinating a technical novelty that in the early stages of its development the quality of its content seemed almost not to matter.
      Fortunately, the dearth of talent was short-lived. Although it would take at least another decade before areas such as news and sports coverage approached their potential, more than enough excellence in the categories of comedy and drama emerged in the 1950s to deserve the attention of discriminating viewers. They are the most fondly remembered of the Golden Age genres for both emotional and intellectual reasons. Live TV drama was, in essence, the legitimate theatre’s contribution to the new medium; such shows were regarded as “prestige” events and were afforded respect accordingly. The comedies of the era are remembered for the same reason that comedy itself endures: human suffering and the ever-elusive pursuit of happiness render laughter a necessary palliative, and people therefore have a particular fondness for those who amuse them.

According to paragraph 2, why would the public gather on the sidewalks in front of stores?

In the West, cartoons are used chiefly to make people laugh. The important feature of all these cartoons is the joke and the element of surprise which is contained. Even though it is very funny, a good cartoon is always based on close observation of a particular feature of life and usually has a serious purpose.
Cartoons in the West have been associated with political and social matters for many years. In wartime, for example, they proved to be an excellent way of spreading propaganda. Nowadays cartoons are often used to make short, sharp comments on politics and governments as well as on a variety of social matters. In this way, the modern cartoon has become a very powerful force in influencing people in Europe and tlie United States.
Unlike most American and European cartoons, however, many Chinese cartoon drawings in the past have also attempted to educate people, especially those who could not read and write. Such cartoons about the lives and sayings of great men in China have proved extremely useful in bringing education to illiterate and semi-literate people throughout China.
Confucius, Mencius and Laozi have all appeared in very interesting Stories presented in the form of cartoons. The cartoons themselves have thus served to illustrate the teachings of the Chinese sages in a very attractive way.
In this sense many Chinese cartoons are different from Western cartoons in so far as they do not depend chiefly on telling jokes. Often, there is nothing to laugh at when you see Chinese cartoons. This is not their primary aim. In addition to commenting on serious political and social matters, Chinese cartoons have aimed at spreading the traditional Chinese thoughts and culture as widely as possible among the people.
Today, however, Chinese cartoons have an added part to play in spreading knowledge.
They offer a very attractive and useful way of reaching people throughout the world, regardless of the particular country in which they live. Thus, through cartoons, the thoughts and teachings of the old Chinese philosophers and sages can now reach people who live in such countries as Britain, France, America, Japan, Malaysia or Australia and who are unfamiliar with the Chinese culture.
Until recently, the transfer of knowledge and culture has been overwhelmingly from the West to the East and not vice versa. By means of cartoons, however, publishing companies in Taiwan, Hong Kong and Singapore are now having success in correcting this imbalance between the East and the West.
Cartoons can overcome language barriers in all foreign countries. The vast increase in the popularity of these cartoons serves to illustrate the truth of Confucius's famous saying "One picture is worth a thousand words.”

No more polar bear?

We all know that the Earth is growing warmer and warmer. This problem is called “global warming”. We also know that global warming is causing a lot of problems. Ocean levels are getting higher and higher. Because ocean levels are getting higher, storms are getting stronger and stronger. This list of problems goes on and on.

Animals are suffering a lot because of global warming. Polar bears are suffering more than most animals. This is because polar bears live in the North Pole. In the North Pole, global warming is making ice melt. Polar bears hunt from large pieces of floating ice. They jump off the ice and hunt for food. Polar bears have to swim and find these floating pieces of ice. These days, they have to swim farther to find the floating ice. Many of them don’t have enough energy. They get too tired, and they die in the water.

Polar bears are suffering because of other problems, too. Pollution makes their water dirty. Many countries go to the North Pole to look for oil and gas, and they damage the environment of the bears. In addition, when ships sail through the North Pole, they cause a lot of damage. Finally, people hunt and kill too many polar bears. However, melting ice is definitely the biggest problem.

Right now, there are about 25,000 polar bears in the world. If global warming continues, there may be only about 12,000 in the year 2050. By the year 2080, that number might be much smaller.

It is important to study polar bears. When we learn about polar bears, we also learn about the health of the North Pole. If polar bears are doing well, then the environment in the North Pole is probably healthy. If polar bears are suffering then there are probably serious problems in the North Pole.

Right now, governments around the world are working to help polar bears. There are new laws that protect polar bears. However, if global warming continues to get worse, polar bears may disappear forever.

Which of the following is true according to the passage?

Very few people in the modern world obtain their food supply by hunting and gathering in the natural environment surrounding their homes. This method of harvesting from nature’s provision is the oldest known subsistence strategy and has been practised for at least the last two million years. It was, indeed, the only way to obtain food until rudimentary farming and the domestication of wild animals were introduced about 10,000 years ago.
Because hunter-gatherers have fared poorly in comparison with their agricultural cousins, their numbers have dwindled, and they have been forced to live in marginal environments, such as deserts and arctic wastelands. In higher latitudes, the shorter growing seasons have restricted the availability of plant life. Such conditions have caused a greater dependence on hunting, and on fishing along the coasts and waterways. The abundance of vegetation in the lower latitudes of the tropics, on the other hand, has provided a greater opportunity for gathering a variety of plants. In short, the environmental differences have restricted the diet and have limited possibilities for the development of subsistence societies.
Contemporary hunter-gatherers may help us understand our prehistoric ancestors. We know from the observation of modern hunter-gatherers in both Africa and Alaska that a society based on hunting and gathering must be very mobile. While the entire community camps in a central location, a smaller party harvests the food within a reasonable distancefrom the camp. When the food in the area has become exhausted, the community moves on to exploit another site. We also notice seasonal migration patterns evolving for most hunter-gatherers, along with a strict division of labor between the sexes. These patterns of behavior may be similar to those practised by mankind during the Paleolithic Period.
