Lead researcher on the atlas, Dr Zoë Randle, said the northerly migration of species of moths and butterflies is a phenomenon observed in northern Europe in recent decades. She said moths are proof that human-made climate change is happening now. Great Britain has observed the arrival of new species too, such as the Clifden Nonpareil, Tree-lichen Beauty and Black-spotted Chestnut. The atlas records that 38 per cent of all moth species in Britain and Ireland have spread to other areas in the last 50 years, most as a result of global warming. The book lists 893 species in all and the scientists’ analysis of distribution records over the period 1970-2016 in particular showed that 31 per cent of 390 larger moth species decreased significantly in Britain. Intensive agriculture has caused the decline of many moth species through the destruction of wildlife-rich habitats and use of fertilizers and pesticides. Widespread environmental pollution such as artificial light at night and chemicals in the air and soil, are altering plant and animal communities in ways that are still not fully understood. Humanmade climate change has facilitated the spread of moths to new parts of Britain and Ireland that were formerly too cold, while at the same time posing a long-term risk to species found in cool and restricted habitats such as mountainsides. The atlas is based on more than 25 million records sourced from Butterfly Conservation’s National Moth Recording Scheme and the Moths Ireland database. These date from the 18th century through to 2016, meaning this volume contains 275 years of mothrecording effort by the public. Dr Randle said the same system of comprehensive recording is not yet available in Ireland as it is in Britain, but anecdotally she believes the same patterns are emerging in Ireland.

Dr. Daniel Quon has been an oral surgeon in Jackson for over 30 years. “Growing up  in the family business, I knew that in order for you to gain something, you have to give back,” Quon said. “And being in the field of dentistry, we have a special gift that we can help people and I thought that was an appropriate way to help out.”  Quon volunteers his dental services at the Jackson Free Health Clinic to patients who can’t afford it. Through the Mississippi Dental Association, Quon also provides free dental care for the Mission Service of Mercy program. Dental Assistant Carley Welch has been a part of this experience. “We actually did that last year together and we plan on doing that again this year together,” he said. “Best boss you can ask for,” Welch continued. “Very patient, always willing to teach you; even things that most people wouldn’t go very far to teach you, he will. Just so you have the experience.” But Quon serves in other ways too. “Wife and I volunteer at the Stewpot. We serve lunch on Saturdays when we can. I was actually on the board of Stewpot for 3 years until this passed year.” And he donates blood platelet at the Mississippi Blood services. “I’m almost up to 18 gallons right now in donations. That’s a lot of blood! still got a little bit left though.” “It takes very little time to volunteer. It’s a great thing where you can help someone who needs an extra hand or helping hand.” “I think he does his part to contribute as much as possible,” Welch added. “Whether it’s helping dental wise or even just in general with the public.”

Once restricted to space stations and satellites, photovoltaics are now gaining popularity and becoming an increasingly viable option. Every day, the sun releases an enormous amount of energy, far more than the entire population consumes. Being that the sun is a sustainable, renewable, and inexhaustible source for generating electricity, not using it seems almost counter-intuitive, especially considering the social and environmental impacts of other forms of energy generation. But the technology to create electricity from the sun is by no means simple and still has some limitations, the most significant being price. The process of turning the sun’s rays into electrical energy all starts in the so-called photovoltaic cell. These cells are produced with two chemically altered silicon layers of which one is missing elections and the other is electron-overloaded. When the photons from the sunlight reach the surface, these electrons gain the ability to move, generating a flow that creates an electric current. Each cell generates a small amount of energy and a panel is usually made of between 36 and 72 photovoltaic cells. By connecting several panels together, a photovoltaic system is created. Eight to ten panels is enough to power a small house. Evidently, however, this statistic is influenced by some factors, such as the efficiency of the panels, the amount of sunshine in the region, and the energy demand of the residence itself.  Importantly, photovoltaic solar panels produce electricity in the form of direct current, meaning the electricity must pass through an inverter to transform it into alternating current - which is what is normally used in buildings, appliances, sockets, and light bulbs. Photovoltaic systems can facilitate energy generation in remote locations where infrastructural networks do not reach. In these cases, the system uses batteries to store electricity when less energy is used than is consumed, such as at night or on very cloudy days. However, it is also possible to use photovoltaics in systems connected to the power grid. In these cases, the excess energy goes to the electricity grid, creating energy “credits” for the building in question. In some countries, it is even possible to sell surplus energy, making the building a power plant for neighbors and method of paying off the investment more quickly.

Read the following passage and choose the best answer (A, B, C, D):
When you graduate from high school or university, is learning finished? The answer is no. In many countries, people continue learning all their lives. Why is lifelong learning important? How can it help you? Lifelong learning can be useful in many ways. People who want to change careers often return to study at a university. Some professions require employees to keep learning new ways to do things. For example, doctors and nurses must always learn about new illnesses and treatments. They must also practise the skills they have and keep learning new ones. Lifelong learning can help people stay healthy and independent. Many older people also feel that lifelong learning helps them stay close to young people. Lots of older people are now learning how to use computers. “I want to remain active … for my own health,” said Mr. Salinas, a 91-year-old man taking computer classes. “I see my computer learning as … part of an active life and something that I can share … with my family.”

Read the following passage and choose the best answer (A, B, C, D):
For many years, scientists have speculated that the cataclysmic impact of an asteroid with the earth was responsible for the demise of the dinosaurs approximately 65 million years ago. Previous discoveries and results have hinted that an asteroid two kilometers in diameter struck the Yucatan peninsula in Eastern Mexico. This impact, stronger than one thousand nuclear explosions, is speculated to have cast a cloud of dust and debris into the atmosphere, covering the entire surface of the earth and blocking out the sun and consequently lowering the surface temperature of the earth. With such a radical change in the earth's environment, scientists believe that over 99% of all animal and plant species were eradicated. Only after millions of years did plants and animals even begin to recover and develop into forms that were better adapted to survive changes in their environment. But, the reign of the dinosaurs had ended and the age of mammals had begun. The crucial link that has held this theory together has been the element iridium. Iridium is not commonly found on either the surface of the earth or inside the crust. It is more commonly found in asteroids or meteorites throughout the solar system. Scientists have hypothesized that after the asteroid impacted the Earth, an even layer of iridium sediment settled over the globe and eventually became part of its surface. The theory, of course, has depended on the discovery of such an existing layer of iridium. Unfortunately, scientists have never been able to offer absolute proof that this asteroid impact ever occurred. Recently, however, a discovery may go a long way toward validating these scientists 'theories. In 1996, a team of marine biologists excavated samples of rock from the Atlantic Ocean just off the cost of Bermuda. Found thousands of meters below the sea, these samples contain iridium similar to those found in the Yucatan peninsula thousands of kilometers away. At first, scientists were skeptical whether the samples were from the same time period. But since carbon dating placed them to 65 million years ago, their doubts were quickly alleviated. Since then many of the other theories for the demise of the dinosaur have been finally laid to rest.

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which (1) __________ carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, (2) __________ rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. While consensus among nearly all scientists, scientific organizations, and governments is (3)__________ climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. Climate change deniers often claim that recent changes (4) __________ to human activity can be seen as part of the natural variations in Earth’s climate and temperature, and that it is difficult or impossible to establish a direct connection between climate change and any single weather event, such as a hurricane.

In any case, economists agree that acting to reduce fossil fuel emissions would be far less expensive than (5) __________ with the consequences of not doing so

Read the following passage and choose the best answer (A, B, C, D):
For 150 years scientists have tried to determine the solar constant, the amount of solar energy that reaches the Earth. Yet, even in the most cloud-free regions of the planet, the solar constant cannot be measured precisely. Gas molecules and dust particles in the atmosphere absorb and scatter sunlight and prevent some wavelengths of the light from ever reaching the ground. With the advent of satellites, however, scientists have finally been able to measure the Sun's output without being impeded by the Earth's atmosphere. Solar Max, a satellite from the National Aeronautics and Space Administration (NASA), has been measuring the Sun's output since February 1980. Although a malfunction in the satellite's control system limited its observation for a few years, the satellite was repaired in orbit by astronauts from the space shuttle in 1984. Max's observations indicate that the solar constant is not really constant after all. The satellite's instruments have detected frequent, small variations in the Sun's energy output, generally amounting to no more than 0.05 percent of the Sun's mean energy output and lasting from a few weeks. Scientists believe these fluctuations coincide with the appearance and disappearance of large groups of sunspots on the Sun's disk. Sunspots are relatively dark regions on the Sun's surface that have strong magnetic fields and a temperature about 2,000 degrees Fahrenheit cooler than the rest of the Sun's surface. Particularly large fluctuations in the solar constant have coincided with sightings of large sunspot group. In 1980, for example, Solar Max's instrument, registered a 0.3percent drop in the solar energy reaching the Earth. At that time a sunspot group covered about 0.6 percent of the solar disk, an area 20 times larger than the Earth's surface. Long-term variations in the solar constant are more difficult to determine. Although Solar Max's data have indicated a slow and steady decline in the Sun's output, some scientists have thought that the satellite's aging detectors might have become less sensitive over the years, thus falsely indicating a drop in the solar constant. This possibility was dismissed, however, by comparing Solar Max's observations with data from a similar instrument operating on NASA's Nimbus 7 weather satellite since 1978.
3. Why is it not possible to measure the solar constant accurately without a satellite?

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.”

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:
We have all had bad experiences with restaurants, stores, or hotels. Maybe you have gone to a restaurant that served terrible food. Perhaps you have gone to a store that had high prices or bad service. Or maybe you have booked a hotel and found out later that the room was nothing like the advertisement.
These days, we have a better chance of preventing these unpleasant surprises. We can do this by using apps. “App” is short for “application”. An app is a computer programme on a smartphone. You can use apps to do almost anything. Apps can help you play games, get directions, talk to friends, and so on.
If f you want to find information about a store or a hotel, you can use a review app. Review apps help us evaluate services and products before we hand over our money. The idea is very simple. After you go to a restaurant or stay in a hotel, you can post a review with one of your apps. You can say anything you want. If you like a hotel you stayed in, you can tell people that it was wonderful. If you think that the food in a certain restaurant was bad, then you tell people not to eat there. Other people can use their apps to read your reviews.
Plenty of people prefer not to use these review apps. Many of these people prefer to go out and decide for themselves whether or not a service is good. However, review apps are getting more and more popular every day. Some apps are for specific services. For example, Tripadvisor focuses on travel, and Goodreads focuses on books. There are also other, larger apps that provide information for just about every service that you can think of. 5

Which of the following would be another good title for the passage?

Read the following passage and choose the best answer (A, B, C, D):
A special education teacher is someone who works with children and youths who have a variety of disabilities. Special education teachers are patient, understanding educators dedicated to giving each individual student the tools and guidance needed to help them maximize success. As schools become more inclusive, special education teachers and general education teachers increasingly work together in general education classrooms. Special education teachers help general educators adapt curriculum materials and teaching techniques to meet the needs of students with disabilities. They coordinate the work of teachers, teacher assistants, and related personnel, such as therapists and social workers, to meet the individualized needs of the student within inclusive special education programs. Special education teachers work in a variety of settings. Some have their own classrooms and teach only special education students; others work as special education resource teachers and offer individualized help to students in general education classrooms; still others teach together with general education teachers in classes including both general and special education students. Some teachers work with special education students for several hours a day in a resource room, separate from their general education classroom. Considerably fewer special education teachers work in residential facilities or tutor students in homebound or hospital environments. The work also can be emotionally demanding and physically draining. Many special education teachers are under considerable stress due to heavy workloads and administrative tasks. They must produce a substantial amount of paperwork documenting each student’s progress and work under the threat of litigation against the school or district by parents if correct procedures are not followed or if the parents feel that their child is not receiving an adequate education. Recently passed legislation, however, is intended to reduce the burden of paperwork and the threat of litigation.

Read the following passage and choose the best answer (A, B, C, D):
Most people have heard about how PTSD can unravel a person. Fewer have heard about posttraumatic growth, the process that lifted Curry out of his despair and into his new role as a leader in the veteran community. The term - defined as “positive change that occurs as a result of the struggle with highly challenging life crises” - was coined in the mid-1990s by Richard Tedeschi, PhD, and Lawrence Calhoun, PhD, after studying how people develop wisdom. They identified five specific ways people can grow after a crisis. First, their relationships strengthen. One woman diagnosed with breast cancer, for example, said she realized her relationships “are the most important things you have.” Bereaved parents told Tedeschi and Calhoun that losing a child had made them more compassionate. Second, they discover new paths and purposes in life. Sometimes these are related to a particular survivor mission. One interviewee became an oncology nurse after losing her child to cancer. Other times, the crisis becomes the catalyst for a more general reconsideration of priorities, as Christine discovered when she started attending The Dinner Party in the aftermath of her mother’s death. Third, the trauma allows them to find their inner strength. The common thread among those Tedeschi and Calhoun studied is a “vulnerable yet stronger” narrative. This paradoxical outlook defined the attitude of a rape survivor who admitted the world seemed more dangerous after the assault, but that, at the same time, she felt more resilient as a result of the inner strength she’d built. Fourth, their spiritual life deepens. That could mean they renew their faith in God, or it could mean they grapple with existential questions more broadly, coming to know certain deep truths about the world or themselves, as one interviewee did after his spinal-cord surgery. Finally, they feel a renewed appreciation for life. Rather than taking for granted a stranger’s kindness or the vivid colors of autumn leaves, they savor the small moments of beauty that light up each day. The difference between those who are able to grow from adversity and those who are stymied lies in what Tedeschi and Calhoun call “deliberate rumination” or introspection. The participants they studied spent a lot of time trying to make sense of their painful experiences, reflecting on how the events changed them. Doing so helped them make the life changes associated with posttraumatic growth.

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.  
5. According to paragraph 4, what can be generalised about the progress of vegetables cooking?

Read the following passage and choose the best answer (A, B, C, D):
From their inception, most rural neighborhoods in colonial North America included at least one carpenter, joiner, sawyer, and cooper in woodworking; a weaver and a tailor for clothing production; a tanner, currier, and cordwainer (shoemaker) for fabricating leather objects; and a blacksmith for metalwork. Where stone was the local building material, a mason was sure to appear on the list of people who paid taxes. With only an apprentice as an assistant, the rural artisan provided the neighborhood with common goods from furniture to shoes to farm equipment in exchange for cash or for “goods in kind” from the customer’s field, pasture, or dairy. Sometimes artisans transformed material provided by the customer wove cloth of yam spun at the farm from the wool of the family sheep; made chairs or tables from wood cut in the customer’s own woodlot; produced shoes or leather breeches from cow, deer, or sheepskin tanned on the farm.  Like their farming neighbors, rural artisans were part of an economy seen, by one historian, as “an orchestra conducted by nature.” Some tasks could not be done in the winter, others had to be put off during harvest time, and still others waited on raw materials that were only produced seasonally. As the days grew shorter, shop hours kept pace, since few artisans could afford enough artificial light to continue work when the sun went down.  To the best of their ability, colonial artisans tried to keep their shops as efficient as possible and to regularize their schedules and methods of production for the best return on their investment in time, tools, and materials. While it is pleasant to imagine a woodworker, for example, carefully matching lumber, joining a chest together without resort to nails or glue, and applying all thought and energy to carving beautiful designs on the finished piece, the time required was not justified unless the customer was willing to pay extra for the quality - and few in rural areas were. Artisans, therefore, often found it necessary to employ as many shortcuts and economics as possible while still producing satisfactory products.

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:
It is said that George Washington was one of the first to realize how important tire building of canals would be to the nation’s development. In fact, before he became the President, he headed the first company in the United States to build a canal, which was to connect the Ohio and Potomac rivers. It was never completed, but it showed the nation the feasibility of canals. As the country expanded westward, settlers in western New York, Pennsylvania, and Ohio needed a means to ship goods. Canals linking natural waterways seemed to supply an effective method.
In 1791, engineers commissioned by the state of New York investigated the possibility of a canal between Albany on the Hudson River and Buffalo on Lake Eric to link the Great Lakes area with the Atlantic seacoast. It would avoid the mountains that served as a barrier to canals from the Delaware and Potomac rivers.
The first attempt to dig the canal, to be called the Eric Canal, was made by private companies but only a comparatively small portion was built before the project was halted for lack of funds. The cost of the prospect was estimated $5 million, an enormous amount for those days. There was some on-again-off-again federal funding, but this time the War of 1812 put an end to construction. In 1817, DeWitt Clinton was elected Governor of New York and persuaded the state to finance and build the canal. It was completed in 1825, costing S2 million more than expected.
The canal rapidly lived up to its sponsors’ faith, quickly paying for itself through tolls. It was far more economical than any other form of transportation at the time. It permitted trade between the Great Lake region and the East coast, robbing the Mississippi River of much of its traffic. It allowed New York to supplant Boston, Philadelphia, and other eastern cities as the chief center of both domestic and foreign commerce. Cities sprang up along the canal. It also contributed in a number of ways to the Norths victory over the South in the Civil War.
An expansion of the canal was planned in 1849. Increased traffic would undoubtedly have warranted its construction had it not been for the railroads.

According to the passage, the Eric Canal connected the

According to the American Red Cross, there’s a 97% chance that someone you know will need a blood transfusion. Blood donors — especially donors with certain blood types — are always in demand. To donate blood, the American Red Cross requires that people be at least 17 years old and weigh more than 110 pounds. (In some states, the age is 16 with a parent’s permission.) Donors must be in good health and will be screened for certain medical conditions, such as anemia. Donors who meet these requirements can give blood every 56 days. Blood donation starts before you walk in the door of the blood bank. Eat a normal breakfast or lunch — this is not a good time to skip meals — but stay away from fatty foods like burgers or fries. And be sure to drink plenty of water, milk, or other liquids. Before donating, you’ll need to answer some questions about your medical history, and have your temperature, pulse, blood pressure, and blood count checked. The medical history includes questions that help blood bank staff decide if a person is healthy enough to donate blood. They’ll probably ask about any recent travel, infections, medicines, and health problems. Donated blood gets tested for viruses, including HIV (the virus that causes AIDS), hepatitis B, hepatitis C, syphilis, and West Nile virus. If any of these things are found, the blood is destroyed. Because blood can be infected with bacteria as well as viruses, certain blood components are tested for contamination with bacteria as well.  Are there any risks? A person can’t get an infection or disease from giving blood. The needles and other equipment used are sterile and they’re used only on one person and then thrown away. The U.S. Food and Drug Administration (FDA) regulates U.S. blood banks. All blood centers must pass regular inspections in order to keep operating. Sometimes people who donate blood notice a few minor side effects like nausea, lightheadedness, dizziness, or fainting, but these symptoms usually go away quickly. The donor’s body usually replaces the liquid part of blood (plasma) within 72 hours after giving blood. It generally takes about 4–8 weeks to regenerate the red blood cells lost during a blood donation. An iron-fortified diet plus daily iron tablets can help rebuild a donor’s red blood supply. The Red Cross estimates that 15% of all blood donors in the United States are high school or college students — an impressive number when you consider you have to be 16 or 17 to donate blood. If you are eligible and want to donate blood, contact your local blood bank or the American Red Cross for more information on what’s involved. You could save someone’s life.  
5. According to the passage, the donors’ blood will be tested the following diseases before donation, EXCEPT ____________
