Tourism and Heritage Protection Travelling is a great thing to do. It helps us learn about different people and different places. Some people travel because they want to see nature. Others travel because they want to make friends and try great food. Of course, a lot of tourists are interested in traditional culture.
Tourism can be very good for traditional cultures. This is because when people travel to another country, they often want to learn more about that country’s traditions, such as music, food, and history. Therefore, the local people in that country will keep their traditional culture alive. They will wear traditional clothing, and sell traditional food. They will also have shows for tourists. These shows can be dances, concerts, plays, or something else.
Tourism also helps people respect each other. If you understand another culture well, you will probably respect that culture much more. You will probably want to protect that culture as well. However, tourism is not always good for traditional culture. Many people say that tourism creates “fake traditional culture”. This means that the local people wear traditional costumes, and do traditional dances only for tourists, but that is not their real lifestyle. Their real lifestyles are similar to the tourists’ lifestyle. They are just pretending because they want to make money.

What is one problem that tourists create?

Long life expectancy can be attributed to a person’s diet - a healthy, balanced diet has been proven to improve longevity. Experts recommend eating at least five portions of a variety of fruit and vegetables every day, basing meals on higher starchy foods like potatoes, bread and rice, having some dairy or dairy alternatives, eating some protein, choosing unsaturated oils and spreads, and drinking plenty of fluids. But new research, published this week, has found the times of day a person eats holds the most benefits. Dr Mark Mattson, a professor of neuroscience at John Hopkins University School of Medicine, in the US, has said “intermittent fasting could be part of a healthy lifestyle.” Intermittent fasting diets usually involve daily time-restricted feeding, which narrows eating times to six to eight hours per day and so-called 5:2 intermittent fasting, in which people limit themselves to one moderate-sized meal two days each week. A range of human and animal studies have shown that alternating between times of fasting and eating supports cellular health, probably by triggering an age-old adaptation to periods of food scarcity called metabolic switching. Such a switch occurs when cells use up their stores of rapidly accessible, sugar-based fuel, and begin converting fat into energy in a slower metabolic process. Dr Mattson says studies have shown that this switch improves blood sugar regulation, increases resistance to stress and suppresses inflammation. Because most Americans eat three meals plus snacks each day, they do not experience the switch, or the suggested benefits. In an article in the New England Journal of Medicine, Dr Mattson said four studies in both animals and people found intermittent fasting also decreased blood pressure, blood lipid levels and resting heart rates.

If you want to spend your time effectively, you can try the following tips. First, make a to-do list every day. Put the most important tasks at the top, even if  they’re things you’re dreading, and tackle them first. Include things you want to do on your list too, so you have items you’re looking forward to. Try motivating yourself with a reward if you get to everything on your list.  Once you know what you need to do, keep your work with you. That way, if you find yourself with extra time – while in the train or bus or waiting for an appointment – you can get something done.  Additionally, don’t be afraid to say no. It’s OK to say no if your friend asks you to go to a movie one night but you have a test the next morning. Instead, find a time that works for both of you and go to see the movie then.  Managing your time also includes finding you productive time. Are you a morning person or a night person? You’ll be more efficient of you work when you’re at your best.  Last but not least, create a dedicated study time. Set up a time devoted only to studying or homework. Shut off you phone and respond to calls or texts when your work is finished. Don’t check email or surf the web (except when you need to for the work you’re doing) during this time either. 
2. Which of the following best replaces the word “extra”?

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 following questions:
It’s often said that we team things at the wrong time. University students frequently do the minimum of work because they’re crazy about a good social life instead. Children often scream before their piano practice 5 because it’s so boring. They have to be given gold stars and medals to be persuaded to swim, or have to be bribed to take exams. But the story is different when you’re older.
Over the years, I’ve done my share of adult learning. At 30, I went to a college and did courses in History and English. It was an amazing experience. For starters, I was paying, so there was no reason to be late - I was the one frowning and drumming my fingers if the tutor was late, not the other way round. Indeed, if I could persuade him to linger for an extra five minutes, it was a bonus, not a nuisance. I wasn’t frightened to ask questions, and homework was a pleasure not a pain. When I passed an exam, I had a big meal, not for my parents or my teachers. The satisfaction I got was entirely personal.
Some people fear going back to school because they worry that their brains have got rusty. But the joy is that, although some parts have rusted up, your brain has learnt all kinds of other things since you were young. It has learnt to think independently and flexibly and is much better at relating one thing to another. What you lose in the rust department, you gain in the maturity department.
In some ways, age is a positive plus. For instance, when you’re older, you get less frustrated. Experience has told you that, if you’re calm and simply do something carefully again and again, eventually you’ll get the hang of it. The confidence you have in other areas - from being able to drive a car, perhaps - means that if you can’t, say, build a chair instantly, you don’t, like a child, want to destroy your first pathetic attempts. Maturity tells you that you will, with application, eventually get there.
I hated piano lessons at school, but I was good at music. And coming back to it, with a teacher who could explain why certain exercises were useful and with musical concepts that, at the age of ten. I could never grasp, was magical. Initially, I did feel a bit strange, thumping out a piece that I’d played for my school exams, with just as little comprehension of what the composer intended as I’d had all those years before. But soon, complex emotions that I never knew poured out from my fingers, and suddenly I could understand why practice makes perfect.

It can be inferred from paragraph 4 that maturity is a positive plus in the learning process because adult learners    .

Light-emitting diodes (LEDs) are now considered the future of lighting due to a lower energy requirement to run, a lower monthly price tag, and a longer life than traditional incandescent light bulbs. Nick Holonyak, an American scientist at General Electric, accidently invented the red LED light while trying to create a laser in the early 1960s. As with other inventors, the principle that some semiconductors glowed when an electric current was applied had been known since the early 1900s, but Holonyak was the first to patent it for use as a light fixture. Within a few years, yellow and green LEDs were added to the mix and used in several applications including indicator lights, calculator displays, and traffic lights, according to the DOE. The blue LED was created in the early 1990s by Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, a group of Japanese and American scientists, and for which they won the 2014 Nobel Prize in Physics. The blue LED allowed scientists to create white LED light bulbs by coating the diodes with phosphor Today, lighting choices have expanded and people can choose different types of light bulbs, including compact fluorescent (CFL) bulbs work by heating a gas that produces ultraviolet light and LED bulbs. Several lighting companies are pushing the boundaries of what light bulbs can do, including Phillips and Stack. Phillips is one of several companies that have created wireless light bulbs that can be controlled via smartphone app. The Phillips Hue uses LED technology that can quickly be turned on or off or dimmed by a flick on a smart phone screen and can also be programmed. The higher-end Hue light bulbs can even be set to a large range of colors (only about sixteen million) and synced with music, movies, and video games. Stack, begun by engineers from Tesla and NASA, developed a smart light bulb using LED technology with a wide range of functions. It can automatically sense the ambient lighting and adjust as needed, it turns off and on via motion sensor when someone enters the room, can be used as a wake up alert, and even adjusts color throughout the day to fit with human’s natural circadian cycles and patterns of natural light. The light bulbs also have a built-in learning program that adapts to inputs given by residents over time. And all of these functions can be programmed or monitored from any smart phone or tablet. It is estimated that Stack smart light bulbs can use about sixty percent less energy than a typical LED light bulb and lasts between twenty and thirty thousand hours depending on the model . These light bulbs are compatible (or soon will be) with many of the options for turning an entire home into a smart home including usage with Amazon Alexa, Google Home, and Apple HomeKit.

With 13,000 floral species and over 15,000 faunal species, three newly discovered big animal species, and a ratio of country/world species of 6.3%. Vietnam has enormous tourismparticularly ecotourism-potential. In fact, since 1986, when Renovation Reforms began the shift from a centrally planned to a socialist-oriented market, or multi-sectoral, economy, tourism has been an sector of primary concern to the government. In May 1995, the prime minister of Vietnam approved a master plan of tourism development for the period 1995- 2010. In February 1999, the state decree on tourism was part of the socio-economic development strategy for the period 2001-2010 approved at the IX National Congress of the Party: “Tourism development has become a spearhead economic industry indeed. It is necessary to improve the quality and effectiveness of tourism activities, bringing into full play the natural conditions, and cultural and historical tradition to meet the domestic and international demand for tourism and to catch up with tourism development in the region” (Document of the IX National Congress 2001). Tourism has so far brought great benefits to the economy, but it has also contributed to environmental degradation, especially biodiversity deterioration. Thus, the concept of “sustainable development”-development which meets the needs of the present without compromising the ability of future generations to meet their own needs - must be factored into tourism development. This consideration is reflected in the term “ecotourism,” which is referred to variously as ecological or environmental tourism, nature or green tourism, sustainable or responsible tourism. Ecotourism involves travel to relatively undisturbed natural areas with the specific object of studying, admiring, and enjoying scenery, plants, and animals, as well as any cultural features found in these areas. It is distinguished from mass or resort tourism by its lower impact on the environment, lower infrastructure requirements, and its role in educating tourists about natural environments and cultural values. Fully aware of its significance, the government of Vietnam has prioritized ecotourism in its strategy for tourism development to ensure both sustainability and economic benefits. Though ecotourism in Vietnam is at a beginning stage of development, it is expected to grow strongly through support from government and international organizations.

Despite the fact that humans haven’t returned to the Moon since the cancellation of the Apollo program in 1972, there have nonetheless been incredible advances in space exploration in recent years. All across the world, human time is the most valuable commodity – particularly when it comes to solving problems. Far from stealing jobs, the majority of advances in artificial intelligence and machine learning are designed to automate relatively “simple” processes and free up time for humans to do what they do best. Already we have had a taste of what AI can achieve from space, even as far back as the early 2000s with the launch of the Earth Observing-1 (EO-1) satellite, which helps analyse and inform the appropriate response in the event of a disaster, such as hurricanes and volcanic eruptions. In some cases, the systems in place on EO-1 began capturing satellite images of disaster zones before ground personnel were even aware that a disaster had occurred. More recently, AI has been used on the Mars Curiosity rover, where AEGIS software is able to identify intriguing rock or soil patches that should be targeted for analysis. This significantly expedites the process of collecting data from the surface of Mars as the robot isn’t relying solely on human commands. Richard Branson’s Virgin Galactic – which hopes to soon begin conducting commercial flights – charges between $200,000 to $250,000 per ticket for a flight where passengers will experience just several minutes of weightlessness beyond the Karman line where space officially begins. Therefore, previous space missions have always needed to consider very carefully which astronauts they send to space, with the ultimate decision often coming down to an astronaut’s ability to act as a ‘jack-of-all-trade’. In future, it should be possible to automate the computing and engineering tasks that historically astronauts have had to train for. This would mean sending individuals with specialised expertise in science and research in place of the all-rounder astronauts of yesteryear. For success in space exploration in the years to come, we will need to continue along the exponential curve of open source uptake and see advances in the approach to how spacecraft software, hardware and infrastructure is developed and deployed. With this baseline in place, advances in AI-driven scientific research have the potential to propel us forwards.
7. Which of the following statements is TRUE, according to the passage?

Read the following passage and choose the best answer (A, B, C, D):
When it comes to cooking, boomers cook one, Generation X cooks another way and the beat generation does things that must be recorded now, because once they have passed out of fashion, they will never be discovered again. They have weird skills, derived from scarcity in their early years. They keep their spices in brown glass because they last longer. For practical purposes, this means everything is in an old Calpol bottle with “sumac” scrawled over it. Some of them are, and will fish an empty packet of sugar out of the bin, shake a quarter-teaspoon of sugar from it and put it back. They can often make a cake by eye, without weighing anything, which I find incredible, and they know what to do with leaf gelatine, which is great until it isn’t. My mother once made avocado in jelly and then said: “I don’t know, the proportions may have been slightly off.” I said, recklessly: “Don’t worry – I’m sure I’ll choke it down,” but when it came to it, my cutlery bounced off it, like a prank played on a very hungry person in a cartoon. The beat generation canon is Meat at Any Price and Fish at Any and anything to do with mince. The descent of mince from a sacred food to a bolognese-only staple is one of the great mysteries of progress, because it is delicious even when you don’t shove a load of tomato in it. But you can’t just shove cheap meat in a pan and watch while it sweats out watery grey juice. This seems to be something that only wartime generations understand. Hip parents in the 70s, or regular parents in the 80s, or quite trad parents in the 90s had a horror of overcooked carrots and waterlogged cabbage. The very smell of cooked vegetables evoked for them every bad memory of British cuisine, before anchovies and Italians and radicchio arrived, when all dinner was a school dinner. So they would all just tease their vegetables with a hint of boiling water, before turning them out, still basically a salad, only a bit warmer. Then you, their offspring, would leave home, and accidentally encounter a vegetable that had been cooked, and realise how delicious it was and now you probably overcook your vegetables a bit, and your children will go the other way.

Read the following passage and choose the best answer (A, B, C, D):
When I tell people about the idea of moving out, many people’s reaction is like, “what do your parents say?” because they assume the parents would not like their children to leave them. Well I don’t know if my parents like it but I can tell you my parents support and respect my decision. They think it is good for me to try and live on my own and then I would know it is the best to stay with my family. The most important reason for independent living is to save the travelling time to work. It used to take me one hour fifteen minutes to travel to work from my previous living place. From my new apartment, it just takes me thirty minutes so I saved forty-five minutes’ traveling time. I don’t have to get up so early and I save two-third of my traveling cost. It does not only save my time to travel for work but also from most of the places in Hong Kong. In addition, I gain my personal space and freedom by independent living. I make my own decision all the time, I do not have to say whether I would go home for dinner, I can invite my friends to come up and stay late. Of course, there are some trade-offs in living on your own. If you want to rent an apartment, there are lots of preparatory work to do. You have to keep visiting the apartments to search for your ideal one. You have to negotiate with the landlord about the price, furniture inclusion, who is responsible for the maintenance of the furniture and equipment. My experience was that after we moved into the apartment, it was not until the kitchen cupboard was soaked with water that we found out there was water leakage in the kitchen sink. Money is the main issue in living on your own. You have to be responsible for all the expenses, for example, the rent, electricity, gas, water, telephone, internet bills, etc.  Therefore, you’ve got to be well prepared and save up for your bills. Although I find my transportation time much shorter, the saved time is spent on other things, such as cooking and some other household chores. I think preparing and cooking the food do occupy a significant portion of my time, therefore I always try to make simple meals. On the other hand, I have to regularly tidy up my apartment and wash my clothes, so it doesn’t really save much of my time after all. Now everything is settled down, I’m getting used to my new life and I am enjoying it. I feel that moving out makes it easier for me to strike a balance between my work, my social life, my study and my family. It may be troublesome but it may worth

The World Health Organization on Wednesday declared the rapidly spreading  coronavirus outbreak a pandemic. Director-General Tedros Adhanom Ghebreyesus said that “We expect to see the number of cases, the number of deaths, and the number of affected countries climb even higher.”  WHO officials had said earlier they were hesitant to call the outbreak a pandemic in case it led governments and individuals to give up the fight. On Wednesday, they stressed that fundamental public health interventions can still limit the spread of the virus and drive down cases even where it was transmitting widely, as the work of authorities and communities in China, Singapore, and South Korea has shown.  The virus, which probably originated in bats but passed to people via an as yet unrecognized intermediary animal species, is believed to have started infecting people in Wuhan, China, in late November or early December. Since then the virus has raced around the globe. South Korea, which has reported nearly 8,000 cases, also appears poised to bring its outbreak under control with aggressive measures and widespread testing. But other countries have struggled to follow the leads of China and South Korea — a reality that has frustrated WHO officials who have exhorted the world to do everything possible to end transmission of the virus. Tedros used the fact that 90% of the cumulative cases have been reported in just four countries as evidence that the rest of the world still had time to prevent an explosion of cases with action.  WHO officials also stressed that countries should be implementing a strategic combination two types of measures. One involves trying to detect and stop known chains of transmission by isolating cases and following and potentially quarantining their contacts. The other involves community-level steps like social distancing and comes into play when the virus is spreading more broadly and transmission chains can’t be tracked. Mike Ryan, the head of the WHO’s emergency program, said that the public health interventions might not have straightforward effect, but to slow the spread of the virus. People with severe cases can require long periods of critical care and strain the resources of hospitals. He said he was worried about “the case load, the demand on the health workers, the dangers that come with fatigue, and potentially shortages of personal protective equipment.”
5. The word “poised” in paragraph 3 is closest in meaning to _______

Read the following passage and choose the best answer (A, B, C, D):
Scientists believe that something very serious is happening to the Earth. It is becoming warmer. Scientists predict that there will be major changes in the climate during the 21st century. Coastal waters will have higher temperatures. This will have a serious effect on agriculture. Farmers will have trouble producing good crops. In warm regions, the weather will be too dry. The amount of water could decrease by 50 per cent. This would cause a large decrease in agricultural production. World temperatures could increase from 1.5 to 5.6 degrees Celsius by the middle of the 21st century. And the increase in temperature could be even greater in the Arctic and Antarctic regions. A rise in temperature could cause the great ice sheets to melt, which, in turn would raise the level of oceans by one to two meters. Many coastal cities would be underwater. Why is all this happening? The Earth and its atmosphere are kept warm by the Sun. The atmosphere lets most of the light from the Sun pass through to warm the Earth. The Earth is warmer by the sunlight and sends heat energy back into the atmosphere. Much of this energy escapes from the Earth’s atmosphere. However, some of it remains. Gases such as carbon dioxide, ozone and water vapor absorb this energy and create more heat. Then, this heat is sent back down to Earth, and the Earth becomes warmer. Recently, however, an increase of carbon dioxide in the atmosphere is causing serious problems. Too much carbon dioxide in the atmosphere prevents heat energy from escaping. Too much heat is sent back down to the Earth, and the amount of carbon dioxide in the atmosphere continues to increase. When oil, gas, and coal burn, they create large amounts of carbon dioxide. The destruction of rain forests that absorb carbon dioxide also helps to increase the amount of carbon dioxide in our atmosphere. Some scientists believe that the amount of carbon dioxide in the air will double by the late 2000s. Scientists call this warming of the Earth and its atmosphere “the greenhouse effect”. A greenhouse, made of glass and plastic, is a special place where plants are grown. The sunlight passes through the glass or plastic and warms the air inside. The heat inside escapes very slowly, so the greenhouse remains very warm. This is exactly what is happening on the Earth. Another reason why the Earth is growing warmer is because of the amount of ozone in our atmosphere. Ozone is a form of oxygen. In the upper atmosphere, very far from the Earth, a layer of ozone helps to protect the Earth from 95 percent of the harmful light that comes from the sun. If your skin receives too much of this light, you would develop skin cancer. We need the ozone layer to protect ourselves. But the ozone layer is in trouble. Scientists have observed that the ozone layer is becoming thin, and above Antarctica there is a hole. This allows too much of the sun’s dangerous light into our atmosphere and makes the Earth warmer. Scientists say we must start making changes and planning now. We need to continue to do research, so we can predict what will happen in the future. We must burn less coal, oil, and gas. Other scientists believe that the problem is not so serious. They think that the Earth is growing warmer naturally, that we don’t need to worry about it now, and that we should just get ready for life in the warmer climate. Most scientists agree that the causes of the world’s climate are very complicated. They say that we must continue to measure the amount of carbon dioxide and ozone in the atmosphere. Scientists also encourage people to learn about the changes that are occurring in the world and how we can all help protect our atmosphere

Birds are even more disrupted by their noisy neighbours than had been thought  previously, researchers have found. And human activities could be preventing birds from reproducing and even developing normal social behaviour and keeping the peace.  A study by Queen’s University Belfast found that when European robins were subjected to human produced noises their behaviour changed. Background noise appeared to mask the communication of crucial information between birds. While aggressive communication is common and birds respond to it, interference through noise can lead to the birds mistaking the signals.  Birds can end up in situations all too familiar to humans. “The birds receive incomplete information on their opponent’s intent and do not appropriately adjust their response,” explained Arnott. “Where song is disguised by background noise, in some cases the male ends up fighting more vigorously than he should, but at other times gives in too easily.”Arnott said the purpose of birdsong was twofold – to attract mates and defend territory. Birds already face an array of human-made dangers, from pesticides and intensive farming to shooting and poisoning. But noise had often been overlooked, the paper in Biology Letters found. A spokesperson for the RSPB said: “Everyone is becoming increasingly concerned that nature is in crisis in the UK, with one in 10 of our wildlife species at threat of extinction. Many of our birds’ populations are already facing a serious crisis as a result of habitat loss, climate change and other human activities. This report is a good reminder that the way we live and our lifestyle has an impact on our natural world, and that we need to protect our natural world if we want to let nature sing.”  For birds, the extra burden of noise pollution adds to extraordinary decline in species, including among once common birds, in recent decades due to such activities as agricultural practice and pesticide use. In the experiment the team used playbacks of robin song to stimulate responses from birds who were territory holders. Simple or complex songs were used in either the presence or absence of noise. The researchers found that song complexity  was used as a signal of aggressive intent; birds demonstrated higher aggressive intent towards complex rather than simple song. This process was disrupted by the presence of added noise.
