Read the following passage and choose the best answer (A, B, C, D):
While light at night can be beneficial, neutral, or damaging for individual species, its presence invariably disturbs ecosystems. For example, some species of spiders avoid lit areas, while other species are happy to build their spider web directly on a lamp post. Since lamp posts attract many flying insects, the spiders that don’t mind light gain an advantage over the spiders that avoid it. Light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. It can confuse animal navigation, alter competitive interactions, change predator-prey relations, and cause physiological harm. The rhythm of life is orchestrated by the natural patterns of light and dark, so disruption to these patterns impacts the ecological dynamics. Studies suggest that light pollution around lakes prevents zooplankton, such as Daphnia, from eating surface algae, causing algal blooms that can kill off the lakes’ plants and lower water quality. Light pollution may also affect ecosystems in other ways. For example, scientists have documented that night time light may interfere with the ability of moths and other nocturnal insects to navigate. Night-blooming flowers that depend on moths for pollination may be affected by night lighting, as there is no replacement pollinator that would not be affected by the artificial light. This can lead to species decline of plants that are unable to reproduce, and change an area’s long term ecology. Reducing light pollution implies many things, such as reducing sky glow, reducing glare, reducing light trespass, and reducing clutter. The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Adjusting the type of lights used, so that the light waves emitted are those that are likely to cause severe light pollution problems

Modern society has given significant attention to the promises of the digital economy over the past decade. But it has given little attention to its negative environmental footprint. Our smartphones rely on rare earth metals, and cloud computing, data centers, artificial intelligence and cryptocurrencies consume large amounts of electricity, often sourced from coal-fired power plants. These are crucial blind spots we must address if we hope to capture the full potential of the digital economy. Without urgent system-wide actions, the digital economy and green economy will be incompatible with each other and could lead to more greenhouse gas emissions, accelerate climate change and pose great threats to humanity. The world’s data centers-the storehouses for enormous quantities of information - consume about three percent of the global electricity supply (more than the entire United Kingdom), and produce two percent of global greenhouse gas emissions-roughly the same as global air travel. A report by Greenpeace East Asia and the North China Electric Power University found that China’s data centers produced 99 million tonnes of carbon dioxide in 2018, the equivalent of about 21 million cars driven for one year. Greenhouse gases aren’t the only type of pollution to be concerned about.Electronic waste (e-waste), which is a byproduct of data center activities, accounts for two percent of solid waste and 70 percent of toxic waste in the United States. Globally, the world produces as much as 50 million tonnes of electronic e-waste a year, worth over US$62.5 billion and more than the GDP of most countries. Only 20 percent of this e-waste is recycled. The world and its intractable challenges are not linear-everything connects to everything else. We must raise awareness about these major blind spots, embrace systems leadership (leading across boundaries), boost circular economy ideas (decoupling economic activity from the consumption of finite resources), leverage an eco-economics approach (an environmentally sustainable economy) and encourage policy-makers to explore the interrelationships between government-wide, system-wide and societal results. We must also consider collective problem-solving by bringing together diverse perspectives from both the Global North and the Global South. We should take an inventory of the global and local damages caused by electronic devices, platforms and data systems, and frame issues about the digital economy and its environmental impact in broad societal terms.

Read the following passage and choose the best answer (A, B, C, D):
Water is of vital importance to all living things. Without it, all living things will  surely die. We also use a great (1)_____ of water daily in our homes, in factories, and in power stations. Most of this water is fresh water and it comes to us from reservoirs, rivers and lakes.  The Earth’s surface is (2)_____ by large areas of water which we call oceans and seas. If you have tasted the water from the sea, you will know that, unlike fresh water, seawater tastes salty. This is due to the (3)_____ of sodium chloride which comes from the land. Rivers carry it to the sea.  Although (4)_______salt nor fresh water has (5)________color, the sea often looks blue in the sunlight. The reason is that sunlight is made up of many colors. Some colors disappear quickly in the sea but blue light bounces back or is reflected, to the surface. This makes the sea look blue. Hence, a stormy sky will make the sea look grey

If you want to make your school green, think beyond your classrooms. Here are some  suggestions that are all easy and simple to follow, and can make a big difference in reducing your carbon footprint and creating a (1)__________ community.  One of the places where both teachers and students often spend some of their time is the library. An eco-friendly reading space is likely to create a favorable impression (2)________ library users, and bring some significant educational benefits. For example, you can install energy-saving products like fans instead of air-conditioners which consume a lot of energy. You can also use biodegradable dust cloths or old T-shirts to clean the environment. In addition, to (3)________ public awareness, allocate a clearly visible space on the noticeboard for everyday green tips like ‘Let others reuse your book’.  Sporty students may prefer to spend more time in the swimming pool than in the library.  Therefore, keeping this place safe and green will also help to raise their environmental awareness. Remember that (4)__________ pool water may cause red eyes and itchy skin to some people if they spend much time in the pool. An ideal alternative would be a salt-water pool, which can be naturally clean and economical. In case warm water is required, think of solar heating to save the environment as one pool with gas or electric heater may emit tons of carbon dioxide each year.  Finally, focus on the school gym, (5)_________ is perhaps the most interactive and exciting place for all school staff. Think of installing low-flow taps and showers to save gallons of water per minute and energy-saving lights to cut the cost of electricity. Moreover, make sure that the airflow pathways are clear and free of mould, mildew and other allergens

Read the following passage and choose the best answer (A, B, C, D):
While family relationships can bring support, joy, and other wonderful benefits into  our lives, these relationships can also bring stress, particularly when there’s unresolved conflict. Because it’s more difficult to let go of conflicted relationships with family than it would be if these relationships were mere friendships, unresolved conflicts with family members can be particularly painful.  We have certain expectations of trust and closeness toward family members, and it can be more than merely disappointing to realize that this may not be possible with all family members. Unresolved family conflicts bring additional stress at family gatherings in particular. Past unresolved conflicts can become the elephant in the room, felt by everyone, but not directly addressed in the situation. This can be stressful for everyone before and during the family gatherings, sometimes leaving a lasting sense of stress afterward as well. Without a heartfelt discussion, an apology or another form of resolution, the trust on both sides is compromised, and may not know what to expect from this person in the future. For example, that one time your mother-in-law criticized your cooking may come up in your mind every time she comes for a visit, and others may sense your tension. This leads many people to assume the worst when they interpret each other’s behavior in the present and future interactions rather than giving the benefit of the doubt as most of us do with people we trust. Also, references or reminders of past conflicts can sting and create new pain.  Once a conflict has gone on a while, even if both parties move on and remain polite, the feelings of pain and mistrust are usually lingering under the surface, and are difficult to resolve: bringing up old hurts in an effort to resolve them can often backfire, as the other party may feel attacked; avoiding the issue altogether but holding onto resentment can poison feelings in the present.  So what do you do at a family gathering when there’s someone there with whom you’ve had an unresolved conflict? Just be polite. Contrary to how many people feel, a family gathering is not the time to rehash old conflicts, as such conversations often get messy before they get resolved — if they get resolved. Again, be polite, redirect conversations that get into areas that may cause conflict, and try to avoid the person as much as you politely can. 
3. According to paragraph 3, what is the consequence for unsettled discord?

Read the following passage and choose the best answer (A, B, C, D):
Deforestation has important global consequences. Forests sequester carbon in the  form of wood and other biomass as the trees grow, taking up carbon dioxide from the atmosphere. When forests are burned, their carbon is returned to the atmosphere as carbon dioxide, a greenhouse gas that has the potential to alter global climate, and the trees are no longer present to sequester more carbon.  In addition, most of the planet’s valuable biodiversity is within forests, particularly tropical ones. Moist tropical forests such as the Amazon have the greatest concentrations of  animal and plant species of any terrestrial ecosystem; perhaps two-thirds of Earth’s species live only in these forests. As deforestation proceeds, it has the potential to cause the extinction of increasing numbers of these species.  On a more local scale, the effects of forest clearing, selective logging, and fires interact. Selective logging increases the flammability of the forest because it converts a closed, wetter forest into a more open, drier one. This leaves the forest vulnerable to the accidental movement of fires from cleared adjacent agricultural lands and to the killing effects of natural droughts. As wildfires, logging, and droughts continue, the forest can become progressively more open until all the trees are lost. Additionally, the burning of tropical forests is generally a seasonal phenomenon and can severely impact air quality. Record-breaking levels of air pollution have occurred in Southeast Asia as the result of burning for oil palm plantations.  In the tropics, much of the deforested land exists in the form of steep mountain hillsides. The combination of steep slopes, high rainfall, and the lack of tree roots to bind the soil can lead to disastrous landslides that destroy fields, homes, and human lives. With the significant exception of the forests destroyed for the oil palm industry, many of the humid forests that have been cleared are soon abandoned as croplands or only used for lowdensity grazing because the soils are extremely poor in nutrients. The vegetation that contains most of the nutrients is often burned, and the nutrients literally “go up in smoke” or are washed away in the next rain. Although forests may regrow after being cleared and then abandoned, this is not always the case, especially if the remaining forests are highly fragmented. Such habitat fragmentation isolates populations of plant and animal species from each other, making it difficult to reproduce without genetic bottlenecks, and the fragments may be too small to support large or territorial animals. Furthermore, deforested lands that are planted with commercially important trees lack biodiversity and do not serve as habitats for native plants
and animals, many of which are endangered species.

People who do not smoke, are not obese, and consume alcohol moderately can expect to live seven years longer than the general population, and to spend most of these extra years in good health, according to a new study published today in Health Affairs. This study was the first to analyze the cumulative impact of several key health behaviours on disability-free and total life expectancy. Previous studies have looked at single health behaviours. Mikko Myrskylä and his colleague instead examined several behaviors simultaneously, which allowed them to determine how long and healthy the lives of people who had avoided most of the well-known individual behavioral risk factors were. The researchers noted that each of the three unhealthy behaviours – obesity, smoking, and unhealthy consumption of alcohol – was linked to a reduction in life expectancy and to an earlier occurrence of disabilities. But there were also differences: smoking was found to be associated with an early death but not with an increase in the number of years with disability, whereas obesity was shown to be associated with a long period of time with disability. Excessive alcohol consumption was found to be associated with both decreased lifespan and a reduced number of healthy years. However, the absence of all of these risky healthy behaviors was found to be associated with the greatest number of healthy years. The most striking finding was the discovery of a large difference in average lifespan between the groups who were the most and the least at risk. Men who were not overweight, had never smoked, and drank moderately were found to live an average of 11 years longer than men who were overweight, had smoked, and drank excessively. For women, the gap between these two groups was found to be even greater, at 12 years. “Our results show how important it is to focus on prevention. Those who avoid risky health behaviours are achieving very long and healthy lives. Effective policy interventions targeting health behaviors could help larger fractions of the population to achieve the health benefits observed in this study,” the researcher emphasized. These results are important not only for individuals, but also for society. In an aging society, the health of the elderly determines the amount of money spent on the health system. In addition, healthy elderly people are better able to participate in the labor market and to perform social roles, such as caring for grandchildren.  
6. Where was the passage possibly taken from?

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:
When another old cave is discovered in the south of France, it is not usually news.
Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940, the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats.
Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.
Early artists drawing these animals accomplished a monumental and difficult task. “They” did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex.
Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside. Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are barely recognizable. To prevent further damage, the site was closed to tourists in 1963, 23 years after it was discovered.

According to the passage, which animals appear most often on the cave walls?

Read the following passage and choose the best answer (A, B, C, D):
Stage and film acting both involve performances in front of an audience. There are fundamental differences between the two. When you act for the stage, you are performing in front of a live audience. That means that your voice and your body movements must be clear even to those seated at the back row. Film acting, on the other hand, requires no voice projection. This is because you are performing in front of the camera. Although a film actor still needs to put the right expression to pull off a role realistically, overdoing movement or being overly expressive actually works against him in film acting because this can be construed as overacting. Controlled and small gestures are the requirements when acting for film. Another difference between stage acting and film acting is the material that is used. Theater involves doing well-known plays time and time again. As such, directors, producers and even avid theater-goers know the plays by heart. Some would even know every line and have developed expectations on how it should be delivered. When a line is not correctly said or the action delivered is not what is expected, an actor can be criticized severely. This is not an issue with film acting because the script is freshly-written. There are basically no expectations on how a role is supposed to be played. Putting the character to life becomes your responsibility and casting directors often choose talents based on their ability to give an authentic and believable performance. The fact that stage acting is done in real time also differentiates it from film acting. The scenes are done in sequence, often building up to a climax. This means that stage actors can’t afford to make mistakes. They have to memorize their lines well or risk forgetting in the middle of the performance. Stage actors must also exhibit quick thinking in case something unexpected happens on stage. Film acting is not done in front of a live audience. Although actors are encouraged to perform the scene perfectly on the first take because of budgetary considerations, a scene can always be redone in case the director is not satisfied with it. When an actor forgets his lines, there is always a script that can be referred back to without causing any damage to the outcome of the movie.

The process of communication has so importance at present moment. It has great expansion and is a necessary agent of socialization. The social communication has great power in the human species, from the origin of the history. The media of social communication can be television, radio, cinema, written or audiovisual press and highways of the information. They do, generally, universalization of the culture of the people. They extend the horizons and the limits between countries. They promote new social models, conducts and values. And they promote a dominant ideology. Often, the media of social communication are very far from the reality of the individuals. They, generally, do not perceive the habitual context of the persons. The social media complement and collaborate in the process of socialization of the new generations, from a positive opinion. Advertising and commercial messaging, pose consumerist models, from a negative perspective. The mass media convert a genuine culture into a consumer society. The advertising stimulates the need to consume, desperately. It transforms the persons into consumers of products. The advertising has a great power on the persons and it transports a serious addiction. The family, the educational system and the society, must allow the process of socialization and formation, to all people. They also must give the tools of analysis and the critique. They also must give offers of interesting things. They must promote the respect to the desires and different opinions. They also must promote the capacity of choice. The mass media influence the children and young people. They have models of identification, values, guidelines and policies. Often, they do not coincide with the own reality. They can serve to think. The mass media influence the process of social adjustment  
5. What is the overall tone of the paragraph 4?

In the mid - nineteenth century, the United States had tremendous natural resources that could be exploited in order to develop heavy industry. Most of the raw materials that are valuable in the manufacture of machinery, transportation facilities, and consumer goods lay ready to be worked into wealth. Iron, coal, and oil - the basic ingredients of industrial growth - were plentiful and needed only the application of technical expertise, organizational skill, and labor.

One crucial development in this movement toward industrialization was the growth of the railroads. The railway network expanded rapidly until the railroad map of the United States looked like a spider's web, with the steel filaments connecting all important sources of raw materials, their places of manufacture, and their centers of distribution. The railroads contributed to the industrial growth not only by connecting these major centers, but also by themselves consuming enormous amounts of fuel, iron, and coal.

Many factors influenced emerging modes of production. For example, machine tools, the tools used to make goods, were steadily improved in the latter part of the nineteenth century - always with an eye to speedier production and lower unit costs. The products of the factories were rapidly absorbed by the growing cities that sheltered the workers and the distributors. The increased urban population was nourished by the increased farm production that, in turn, was made more productive by the use of the new farm machinery. American agricultural production kept up with the urban demand and still had surpluses for sale to the industrial centers of Europe.

The labor that ran the factories and built the railways was recruited in part from American farm areas where people were being displaced by farm machinery, in part from Asia, and in part from Europe. Europe now began to send tides of immigrants from eastern and southern Europe - most of whom were originally poor farmers but who settled in American industrial cities. The money to finance this tremendous expansion of the American economy still came from European financiers for the most part, but the American were approaching the day when their expansion could be financed in their own " money market".

The ruined temples of Angkor are perhaps one of the most impressive Seven Wonders of the World. Located in modern day Cambodia near Lake Tonle Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire for the ninth to the fifteenth century. The ruins of Angkor are documented as some of the most impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archaeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.
One possible explanation for the downfall of the Khmer Empire has to do with the inhabitant’s irrigation system. The temples and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding paddies and farmland during the course of the year. Farmers were completely dependent on the water for their crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.
Scientists speculate that toward the end of the Khmer Empire the hydraulic system of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food more quickly and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and loss of water led to decrease in the food supply. With the less food available, the people of Angkor slowly began to migrate to other parts of Cambodia, thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.

Just as optical fibers have transformed communication, they are also revolutionizing medicine. These ultra - thin, flxible fiers have opened a window into the living tissues of the body. By inserting optical fibers through natural openings or small incisions and the threading them along the body's established pathways, physicians can look into the lungs, intestines, heart and other areas that were formerly inaccessible to them. The basic fiber-optics system is called fiberscope, which consists of two bundles of fibers. One, the illuminating bundle, carries light to the tissues. It is coupled to a high-intensity light source. Light enters the cores of the high-purity silicon glass and travels along the fibers. A lens at the end of the bundle collects the light and focuses it into the other bundle, the imaging bundle. Each fibers in the bundle transmits only a tiny fraction of the total image. The reconstructed image can be viewed through an eyepiece or displayed on a television screen. During the last five years, improved methods of fabricating optical fibers have led to a reduction in fiberscope diameter and an increase in the number of fibers, which in turn has increased resolution. Optical fibers can also be used to deliver laser light. By use of laser beams, physicians can perform surgery inside the body, sometimes eliminating the need of invasive procedures in which healthy tissue must be cut through to reach the site of disease. Many of these procedures do not require anesthesia and can be performed in a physician's office. These techniques have reduced the risk and the cost of medical care.

Read the following passage and choose the best answer (A, B, C, D):
An American game that has traveled well is basketball, now played by more than 250 million people worldwide in an organized fashion, as well as by countless others in “pick-up” games. Basketball originated in 1891 when a future Presbyterian minister named James Naismith (1861-1939) was assigned to teach a physical education class at a Young Men’s Christian Association (YMCA) training school in Springfield, Massachusetts. The class had been noted for being disorderly, and Naismith was told to invent a new game to keep the young men occupied. Since it was winter and very cold outside, a game that could be played indoors was desirable.  Naismith thought back to his boyhood in Canada, where he and his friends had played “duck on a rock,” which involved trying to knock a large rock off a boulder by throwing smaller rocks at it. He also recalled watching rugby players toss a ball into a box in a gymnasium. He had the idea of nailing up raised boxes into which players would attempt to throw a ball. When boxes couldn’t be found, he used peach baskets. According to Alexander Wolff, in his book 100 Years of Hoops, Naismith drew up the rules for the new game in “about an hour.” Most of them still apply in some forms today.  Basketball caught on because graduates of the YMCA school traveled widely, because Naismith disseminated the rules freely, and because there was a need for a simple game that could be played indoors during winter. Naismith’s legacy included the first great college basketball coach, Forrest “Phog” Allen (1885-1974), who played for Naismith at the University of Kansas and went on to win 771 games as a coach at Kansas himself. Among Allen’s star players was Wilt Chamberlain, who became one of professional basketball’s first superstars – one night in 1962, he scored a record 100 points in a game.  The first professional basketball league was formed in 1898; players earned $2.50 for home games, $1.25 for games on the road. Not quite 100 years later, Juwan Howard, a star player for the Washington Bullets (now called the Washington Wizards), had competing offers of more than $100 million over seven seasons from the Bullets and the Miami Heat.  Many teams in the National Basketball Association now have foreign players, who return home to represent their native countries during the Olympic Games. The so-called Dream Team, made up of the top American professional basketball players, has represented
the United States in recent Olympic Games. In 1996 the Dream Team trailed some opponents until fairly late in the games. In Athens in 2004 Argentina took home the gold, the first time a Latin American country won the basketball honor.
