Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership. “Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources,” he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism." Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world’s 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newpaper, Boley and coauthor Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state. Ecotourists not only provide a boost to the economy in such places, they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection. “The public has become increasing less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public’s interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas

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.
 Right now, the biggest source of energy in the world is fossil fuel. Fossil fuels are oil, gas, and coal. More than 80 percent of the world's energy comes from fossil fuel. There are many problems with fossil fuel. One problem is that when fossil fuel is burned, it pollutes the air. Also, when we take fossil fuel from the Earth, we often cause a lot of damage. Another problem is that we are running out of it. That is why we need new sources of energy. A big source of energy for many countries is nuclear power. Thirty-one countries use nuclear power. Many ships also use it.
 Nuclear power has some advantages. First of all, we can't run out of nuclear power. Nuclear power does not make the air dirty. Also, if a country has nuclear power, it doesn't need to buy as much as oil from other countries.
 However, there are also a lot of problems that come with nuclear power. For example, nuclear accidents are very serious. In 1986, there was a nuclear accident in Ukraine. In the next 20 years, about 4,000 people got sick and died. In 2011, there was another very serious nuclear accident in Japan. Japan is still trying to clean up the nuclear waste from the accident.
 Many people don't want nuclear power in their countries. They say that it is not safe. A lot of people want their countries to use safer and cleaner ways to get electricity. There have been protests against nuclear energy in the United States, Russia, France, Taiwan, Japan, India, and many other countries.
 Although many people hate nuclear energy, more and more countries are using it. One reason for this is that the world is using more and more energy. We just don't have enough fossil fuel. However, if we use nuclear power, then we may have more serious problems in the future.

Naturalists in the developed countries were largely split between conservationists and  preservationists. This battle is no better demonstrated in the US than during the Progressive Era of 1890-1920.  While the existing economic paradigm was one of laissez-faire economics that many felt was damaging the natural environment and integrity of natural resources, the conservationist movement led by Theodore Roosevelt was deeply concerned about the wastage and harm it was doing to the land, leading to a large number of game species in the US on the brink of extinction in less than a century. Then there were the preservationists who argued that the proposals of the emerging conservationists did not go far enough. This was certainly the view of John Muir who believed that there was still too much concern for the economic value of land rather than the need for preservation of pristine landscapes. Muir’s Sierra Club made a stand with the development of the Hetch Hetchy Dam in Yosemite, arguing that the land should be kept pristine and the valley protected.  As president, Roosevelt pushed strongly for conservation issues which may be the reason they eventually won the day. During his term in office, around 230m acres of land were put under Federal protection, established the US Forestry Service, and created five national parks, and several national forests. That’s not to say that preservationists did not have their victories. In the 1960s, the Wilderness Actset aside large tracts of land with minimal human impact and of particular cultural, scientific, or natural interest. In these areas, logging, mining and other industrial activities are prohibited and there are strong protections in place to maintain the integrity of natural water sources partly for the ecosystem and partly for industrial and commercial developments downstream of the water flow.

Spend just a minute watching the world population counter tick up on Worldometers and you’ll see just how quickly we’re swelling in numbers. The current figure stands at around 7.7 billion, and this is projected to become 9.8 billion by 2050, according to the UN. More people means more carbon footprints - more cars, waste and emissions, more houses and infrastructure to be constructed using the world’s limited resources, more mouths to be fed using more water and energy in food production. Governments recognise the severity of the situation and have mostly come together over global policies like the UN’s Paris Agreement, to limit carbon emissions and their impact on climate change. In addition, new technologies are being developed to make our use of resources more efficient. As for controlling population growth, the education of women is one key factor. Research shows the higher level to which a woman is educated, the fewer children she is likely to have. In Ghana, for example, women who have been to high school, have a fertility rate of between two and three children, compared with six for those who have no education. This could be for several reasons including learning about desired family size and understanding child health better. This means that the mother is more confident her children will survive. She is also likely to hold more sway within the family, arguing for fewer children if that is what she wants.  There is also plenty that individuals can do to reduce their personal footprint. Earth Overshoot Day is defined as the day when humanity has used up nature’s resource budget for the year. The Global Footprint Network calculates that moving Earth Overshoot day back by five days every year would mean that, by 2050, we’d be using the resources of less than one planet. Just eating 50% less meat and replacing it with vegetarian alternatives could save the planet five days. As David Attenborough says, if we want to save Earth, we can no longer afford to keep eating meat: “We are omnivores, so biologically, if you could have a biological morality, you can say, yes we evolved to eat pretty well everything. But now we’ve got to a stage in our own social evolution in which that is no longer practical.” Sir David says he himself now eats less meat and is bolstered by the knowledge that it’s helping the planet.

   The White House, the official home of the United States president, was not built in time for George Washington to live in it. It was begun in 1792 and was ready for its first inhabitants. President and Mrs.John Adams, who moved in on November 1, 1800. When the Adamses moved in, the White House was not yet complete, and the Adamses suffered many inconveniences; for example, the main staircase was incomplete, which hindered movement from floor to floor, and the future laundry yard was merely a pool of mud, so wet laundry was hung in the unfinished East Room to dry. Thomas Jefferson, the third president, improved the comfort of the White House in many respects and added new architectural features such as the terraces on the east and west ends.

   When the British forces burned the White House on August 24, 1814, President Madison was forced to leave.All the remained after the fire was the exterior walls, the interior was completely destroyed. It was not until December of 1817 that the following president, James Monroe, was able to move into a rebuilt residence. Since then, the White House has continued to be modified but has been continuously occupied by each succeeding U.S president.

It can be inferred from the passage that John Adams was:

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

October brings attention to breast cancer, by raising awareness of treatment, research  and prevention. One local company is going a step above the rest, by offering a free home cleaning to a patient undergoing treatment. Cleaning for a Reason is an international organization that provides home cleanings for family members battling cancer.  “I am a breast cancer survivor myself, I was diagnosed in 2011. And so when I found out about this in 2014, after going through my experience of being extremely tired and just no energy at all to perform day to day tasks, that I realized this would be something that would greatly benefit the women in our community,” said Marlo Kanipe, owner of Deserved Comfort House Cleaning. The company partners with Cleaning for a Reason to provide the service locally.  Columbia native Lenora Floyd was diagnosed with breast cancer in 2018, and learned about Cleaning for a Reason from a flyer. “I was sitting at the table and I thought ‘that’s really something that would be such a huge help!’ Because I do most of the cleaning around the house, and I didn’t really know what to expect,” said Floyd. Floyd said having a clean home lifted a burden while she was going through a tough time. “It was just really nice to have that service, and one less thing not to have to worry about. Be able to rest instead of thinking ‘oh, I really need to vacuum up,’” said Floyd. “The chemotherapy and radiation really just takes a toll on your body. When someone is going through those times, the last thing you want to do is to have to do physical work. And house cleaning, of course, is physical work,” said Kanipe. “It’s nice to be able to take one small thing off of their plate. That they don’t have to worry about cleaning or keeping their house clean,” said Nicka Evans, a certified cleaning technician with Deserved Comfort. “This is what I do for work, it doesn’t seem like it’s a big deal. But to be able to come into someone’s house and see that it is a big deal and it’s important to them, it really means a lot to me.”  Since partnering with Cleaning for a Reason in 2014, Deserved Comfort has donated about $15,000 worth of cleanings. They will continue to help and be there for people as they battle cancer.

We’re all born with a passion for learning that for many of us sadly fades over time. A mindset of continuous learning best positions us for an ever-evolving future. Dr. Carol Dweck, a psychologist and Stanford professor, distinguishes between a fixed mindset and a growth mindset. In a fixed mindset, people believe that their basic qualities, like intelligence or talent, are fixed traits. They believe that talent alone, without effort, creates success. They believe that they are “smart” or “dumb” and that there is no way to change. No matter how hard they work at something, a ceiling prevents them from getting better. In a growth mindset, people believe that their basic abilities can be developed through dedication and hard work. Brains and talent are a starting point. This view creates a love of learning and a resilience that is essential for great accomplishments. The sky is the limit. It’s not about proving yourself, it’s about improving yourself. “Future Shock” author Alvin Toffler once said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn and relearn.” Learning and relearning can be fun. Unlearning is hard. It’s hard discarding old thinking, protocols, treatment plans, business practices and communication styles. But that hard work is necessary to progress and grow as people and professionals. Unlearning is particularly difficult for adults; kids are good at it. Our thinking becomes more rigid as we age. How difficult was it for medical professionals of the past to unlearn bloodletting, lobotomies, arsenic and mercury treatments, urine for teeth whitening, shock therapy, and heroin for children’s coughs? All were considered contemporary medicine in our great-grandparents’ day. The importance of learning, unlearning and relearning has never been more important than in today’s rapidly changing workplace

Simmons Research conducted a survey of American adults in order to learn how much Americans at large trust the media, and we are pleased to present the results in this first Simmons News Media Trust Index. We asked respondents to let us know how trustworthy or untrustworthy they found 38 of the largest and most well-known news sources commonly available in the US. News sources included represented a wide variety of mediums, including print, online, radio, and television with many of them operating across platforms. The average percentage of respondents who rated news sources as trustworthy or very trustworthy was just 40.1% - not a ringing endorsement for journalism in general. Topping the list across all news sources, and the only newspaper in the top five, was the Wall Street Journal with 57.7% of Americans trusting them. The major television network news organizations also fared quite well in our survey, taking the second (ABC 55.9%), third (CBS 55.4%), and sixth (NBC 54.1%) most trusted positions. Among cable news, the most trusted network in the US was ironically not American. BBC News was trusted by 55.2% of Americans and was the fourth most trusted news source. CNN, which touts itself as the “most trusted name in news,” trailed the list at number 14 with the trust of 46.1% of Americans. Forbes was the most trusted magazine and rounded out the top five, trusted by 54.2% of Americans. The New York Times and the Washington Post were both among the most trusted news organizations in our survey. The New York Times came in at the seventh position trusted by 53.8% of Americans, and the Washington Post in eighth trusted by 53.6%. USA Today (51.1%) and the Washington Times (50.0%) were the final two sources trusted by at least a majority of Americans. The least trusted news sources were all Internet-first and hyper-partisan in nature representing brands that have been consistently rated as misleading and inaccurate by factcheckers. The six organizations trusted least were split evenly between far-left and far-right news sources, and on average were trusted by only about one in four Americans. Daily Caller was the bottom of our list, with just 22.5% trusting them. They were followed by another extremely conservative platform, InfoWars, at 24.3% which was recently banned or had content deleted from Facebook, YouTube, iTunes, and Spotify for violating terms of service around hate speech, harassment, and bullying

Read the following passage and choose the best answer (A, B, C, D):
The walnut tree produces wood that is used for countless purposes, and is considered the finest wood in the world. The wood is easy to work with, yet it is very hard and durable - and when it is polished, it produces a rich, dark luster. It also shrinks and swells less than any other wood, which makes it especially desirable for fine furniture, flooring, and even gun stocks. In fact, just about every part of the walnut is unusually hard and strong. The nut of the tree is encased inside a very hard shell, which itself is enclosed in a leathery outer covering called a husk. It requires real effort to break through those layers to get at the tasty meat inside. Yet every part of the walnut is useful to people. The outer husk produces a dark reddish stain that is hard to remove from the hands of the person who opens the nut, and this pigment is widely used in dyes and wood stains. The inner shell is used as an abrasive to clean jet engines. And the meat of the nut is extensively used in cooking, ice cream, flavourings - and just eaten raw. Walnut trees exude a chemical into the soil near their roots which can be poisonous to some trees and shrubs. Fruit trees, for example, will not survive if planted too close to a walnut. Many other plants, such as maple trees or ivy, are not affected by the walnut’s presence, and are well-suited to grow in its vicinity

New data from Akamai, an internet delivery and cloud services company, has exposed that the video game industry remains a growing threat vector for security breaches. Hackers have targeted 12 billion credential stuffing attacks against game websites within a 17-month period The rise and success of credential stuffing attacks is a result of people continuing to reuse the same passwords across multiple accounts. Google identified that 59% of online users reuse passwords. When a data breach happens, user credentials are exposed and can subsequently be found on the internet and the dark web. Cybercriminals use a bot with a list of exposed credentials against a website to gain access to an account on that site. The reason that gaming is subject to so many breaches is twofold; No. 1, most video game companies use low-friction authentication measures because increasing friction drives customer attrition and results in a loss of revenue. The second issue is that from a consumer perspective, gaming is seen as having a low financial risk and, as a result, gamers tend to use less secure passwords. Adding to these challenges is the fact that game developers are pressured to deliver more products at a faster pace, meaning there are more bugs and security issues for cybercriminals to exploit. This has created a perfect storm in the video game industry upon which hackers are all too eager to capitalize.   A significant number of gamers are young — elementary, middle, and high schoolaged — who are less security-conscious and more trusting of people they meet online. To them, privacy is a learned behavior leaving them open to exploitation. They may need to be taught best practices to safeguard their accounts and understand the risks of using weak passwords linked to the games they play. Providing a seamless online experience is paramount in the digital age and, as a result, many organizations balk at implementing robust security procedures for fear of alienating customers. The challenge for the video game industry is to find a balance between increased security without frustrating its players. One notable exception is Microsoft, which has deployed vigorous security measures with Xbox in line with the rest of its business. Without a fundamental change in approach from both gamers and the industry overall, the escalation of this problem shows no signs of slowing down.

"Ever since humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is completed through sign language in which motions stand for letters, words, and ideas. Tourists, and the local people unable to make themselves understood by each other through speaking or writing have had to use this form of expression. Many of these symbols of whole words are very lively and exact and can be used internationally, spelling, however, cannot compare with them.
 Body language sends ideas or thoughts by certain actions, either intentionally or unintentionally. A wink can be a way of showing that the party is only joking. A nod means approval, while shaking the head indicates a negative reaction.
 Other forms of nonlinguistic language can be found in Braille (a System of raised dots read with the fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warn, and instruct people.
 All in all, while words are the most common form of communication, other Systems and techniques nonlinguistic also play role of expressing human thoughts and feelings."

According to airline industry statistics, almost 90 percent of airline accidents are survivable or partiallysurvivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instruction before take off and ask questions if you have uncertainties. You should fasten your seat belt low on your hips and as tightly as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings, you are advised to keep your feet flat on the floor. Before take off, you should locate the nearest exit and an alterative exit and count the rows of seats between you and the exits so that you can
reach them in the dark if necessary. In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the planes comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and smoke near the wreckage

Read the following passage and choose the best answer (A, B, C, D):
Geothermal energy is the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called mác-ma. Almost everywhere, the shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature between 50° and 60°F (10° and 16°C). Geothermal heat pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water. In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii. Wells can be drilled into underground reservoirs for the generation of electricity. Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Hot water near the surface of Earth can be used directly for heat. Direct-use applications include heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes such as pasteurizing milk. Hot dry rock resources occur at depths of 3 to 5 miles everywhere beneath the Earth’s surface and at lesser depths in certain areas. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rock, and drawing off the heated water from another well. Currently, there are no commercial applications of this technology. Existing technology also does not yet allow recovery of heat directly from mác-ma, the very deep and most powerful resource of geothermal energy

Across the panel, there was a consensus that the younger generations are not engaging with print media to the same extent, or in the same ways as previous generations. According to Stefan Uhl, young people continue to view print media as something “old fashioned” and if brands want to ensure their survival, they must go where the customers are and introduce an omnichannel approach. Gerhard Louw, head of global media at Deutsche Telekom echoed this sentiment by saying that if the draw of print media is “attractiveness and relevance then I think everything is happening in video. We’re talking about video and movement in everything, and if there’s a problem with print it’s that it doesn’t have that…we are being led down a path where all the excitement, all the action is going there and that’s a big problem for print.” However, as managing director of Carat Germany, Stefan Uhl suggested that this was leading to a situation of neglect for print media and that its possibilities are not being adequately explored: “[print media] has to fit to a brand’s communications target, but there are some instances where print can deliver better than any other channel. “To me, print is a one screen channel – meaning high impact - and it’s one of the very few channels left that I’m hoping somebody will focus on. I just haven’t seen an initiative talking about that strength from the print industry.” The real question, however, remains is whether we can re-introduce this medium to the younger generations, and teach them how to use print again, said Rob McIntosh, executive principle at Eight Inc and the former chief brand officer at Esprit. “And will that be successful?” he asked.

As cases of coronavirus infection proliferate around the world and governments take extraordinary measures to limit the spread, there is still a lot of confusion about what exactly the virus does to people’s bodies. The symptoms — fever, cough, shortness of breath — can signal any number of illnesses, from flu to strep to the common cold. The virus is spread through droplets transmitted into the air from coughing or sneezing, which people nearby can take in through their nose, mouth or eyes. The viral particles in these droplets travel quickly to the back of your nasal passages and to the mucous membranes in the back of your throat, attaching to a particular receptor in cells, beginning there. Coronavirus particles have spiked proteins sticking out from their surfaces, and these spikes hook onto cell membranes, allowing the virus’s genetic material to enter the human cell. That genetic material proceeds to “hijack the metabolism of the cell and say, in effect, ‘Don’t do your usual job. Your job now is to help me multiply and make the virus,’” said Dr. William Schaffner. As copies of the virus multiply, they burst out and infect neighboring cells. The virus then “crawls progressively down the bronchial tubes,” Dr. Schaffner said. When the virus reaches the lungs, their mucous membranes become inflamed. That can damage the alveoli or lung sacs and they have to work harder to carry out their function of supplying oxygen to the blood that circulates throughout our body and removing carbon dioxide from the blood so that it can be exhaled. The swelling and the impaired flow of oxygen can cause those areas in the lungs to fill with fluid, pus and dead cells. Pneumonia, an infection in the lung, can occur  
1. What is the topic of the passage?

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
We have all heard the expression, “you can’t judge a book by its cover.” However, it seems that is exactly what most people do. The human brain seems to be wired in such a way that we make very strong, lasting judgments about the people we meet within the first 30 seconds. And it is true, you may be able learn a lot about a person by their first impression. But can you really learn all you need to know?
May be there is something affecting your first impression. Possibly the person is nervous or upset. Maybe you are in a bad mood or not feeling well. All of these factors and more could influence a first impression, so should people place so much weight on it?
Many people feel that a first impression is extremely important. Once those people form an idea of you, it is often difficult for them to get beyond it. If someone feels that you are something you really aren’t because of your first impression, then that is obviously not a good thing.
Yet many people really do still rely deeply on first impressions. One good example is the job interview. We dress nicely for job interviews for a very good reason: to make a good first impression. In addition to our outward appearance, many people tend to put on something of an act. By being extremely polite and showing interest, we feel that we will make a good first impression and have a better chance getting the job.
Is this the way things should be? Probably not. Will this situation ever change? The answer to that question is the same - probably not. It is just human nature to rely on a first impression. Everyone knows that they do it and most people know that it's not the right thing to do.

What is the passage mainly about?
