In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, etc... This may not be true in some other countries, however. An American professor discovered this difference while teaching a class in a Brazilian university. The two-hour class was scheduled to begin at 10 a.m, and end at 12 a.m. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 11 a.m. Although all of the students greeted the professor as they arrived, few apologised for their lateness. Were these students being rude? He decided to study the students’ behavior.
In American university, students are expected to arrive at the appointed hour. On the other hand, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but they also end at the scheduled time. In the Brazilian class, only a few students left the class at noon, many remained past 12:30 to discuss the class and ask more questions. While arriving late may not be important in Brazil, neither is staying late.
The explanation for these differences is complicated. People from Brazilian and North American cultures have different feelings about lateness. In Brazil, the students believe that a person who usually arrives late is probably more successful than a person who is always on time. In fact, Brazilians expect a person with status or prestige to arrive late, while in the United States, lateness is usually considered to be disrespectful and unacceptable. Consequently, if a Brazilian is late for an appointment with a North America, the American may misinterpret the reason for the lateness and become angry.
As a result for his study, the professor learned that the Brazilian students were not being disrespectful to him. Instead, they were simply behaving the appropriate way for a Brazilian student in Brazil. Eventually, the professor was able to adapt his own behavior to feel comfortable in the new culture.

There are many types of family systems around the world. In North America and  northern Europe, the nuclear family (with two generations - a father, a mother and one or more children) is often seen as the most typical. In contrast, in most other parts of the world, extended families, which include other family members such as grandparents, aunts, uncles and cousins, are seen as the norm.  The common view is that the nuclear family has become the norm in many Western societies as a result of industrialization and urbanization. This trend began in the late eighteenth and nineteenth centuries, when people were forced to move to cities to find work in the factories that sprang up during the Industrial Revolution. In the twentieth century, greater industrialization resulted in even more people leaving their large extended families. Urbanization also meant that people lived in much smaller houses, which were not big enough for an extended family.  The trend towards nuclear families meant that many of the duties and responsibilities of a family, such as providing food and shelter, cleaning the home, preparing the food, caring for children and their education, and caring for the sick and elderly are no longer shared among the members of the extended family. The parents (or parent) now have to do this, with some help from the state. However, this is the price that people pay for the higher standard of living that may come from living in a city.  We may think we know what we mean by a ‘nuclear’ family and an extended family, but reality is more complicated than most people believe. Most nuclear families are part of extended families: children have grandparents and, in many cases, aunts, uncles and cousins as well. Part of what makes them ‘nuclear’ is that they live in their own separate household, but it is not the whole story. In Greece or Italy, for example, a nuclear family may live in its own flat, but the extended family may live in the same apartment block or in the same street and family members see each other and even eat together every day. There is at least one more factor to consider. Family members may be separated from each other by geographical distance, but they may have close emotional ties. Even in North America and northern Europe, grandparents usually have close bonds with their grandchildren, and families often travel long distances so that they can see each other. Grandparents often help their adult children, for example, by cooking and looking after their children in emergencies. In the same way, when their parents become too old to live on their own, adult children may take them into their own homes. As a result, they turn their nuclear family into an extended family.  The structure of families changes over time. The effects of urbanization and industrialization are enormous, but they are not the only reasons for the changes. People marry, have children, become widowed, divorce and die. Children grow up and adults grow old. Nuclear families become extended families and extended families become nuclear families. Family ties stay strong or become weak. One thing is certain: in a changing world, the family will continue to change, but ultimately, it is likely to continue to be the basic unit of society

Read the following passage and choose the best answer (A, B, C, D):
There are a number of initiatives, some already introduced and some in the pipeline,  that are specifically designed to ensure that the economic value of nature is recognised. One example is reduced emissions from deforestation and forest degradation, under  which forest owners are paid not to cut down trees. A number of governments across the world have committed hundreds of millions of dollars to these projects. Another is habitat banking, the market for which currently stands at around $3bn in the US, where companies that degrade natural areas are forced to restore nature elsewhere. Trade in forest conservation obligations in Brazil and ground-water salinity credits in Australia have also proved successful. Alongside these schemes and those like them, there are various compensation arrangements that make those causing environmental damage pay for it, just like carbon credits that currently exist. Exemptions from these various taxes, charges and fees, as well as subsidies, are also used to encourage environmentally responsible behaviour.  There is also growing pressure for companies to begin incorporating the costs of the damage that they do to the Earth’s natural resources into their profit and loss accounts. Only by incorporating these costs into their accounts, many argue, will companies be forced to reduce their impact on the natural world. "Directors’ bonuses don’t have to be included in company accounts from a pure profit and loss point of view, but they are. Environmental externalities should be the same," says Pavan Sukhdev, a career banker and team leader of the United Nations’ The Economics of Ecosystems and Biodiversity study.  “This is not a straightforward process and needs standard methodologies accepted by everyone, but it could be achieved within 10 years.” The next step would be to incorporate environmental assets into national accounts.

Children’s behaviour has worsened over the past five years, according to a survey of  teachers which found that a fifth thought girls were more likely to cause trouble than boys. The survey, published after teachers at a Lancashire school went on strike over discipline, found low-level disruption, including chatting and “horsing around”, was the biggest problem. Boys were more likely to be physically aggressive while girls tended to ostracise other pupils. The behaviour of boys was more of a challenge than that of girls but the actions of each sex had deteriorated, according to 56.5% of staff surveyed by the Association of Teachers and Lecturers (ATL).  Among male pupils the most challenging behaviour for teachers was physical aggression, such as pushing, spitting, kicking and hitting. A secondary teacher quoted in the survey said boys were usually aggressive with other pupils, while girls tended to call one another names. Teachers criticised a lack of role models in the home. A primary teacher said: “The boys are far more willing to be aggressive to adults, verbally and even physically. There don’t seem to be any parental boundaries set of what is an appropriate way to speak and deal with another adult.” Teachers at Darwen Vale high school, Lancashire, walked out over unruly pupil behaviour this month. They said children challenged them to fights and threatened to film lessons and post them online. The survey of more than 850 teachers, heads and other school staff found that more than 21% thought girls’ behaviour was more challenging than boys, compared with 68% who said male pupils caused more trouble. In schools that have excluded pupils, 57% said more boys and 5% said more girls had been excluded. A department head in a primary school told the survey, carried out in March, that “classes with a majority of boys tend to be louder, less co-operative and harder to teach”. Nearly half of the staff surveyed said boys’ bravado was behind their disruption. For girls, the most likely trigger was a break-up between friends. A primary school teacher from Bedfordshire said: "Boys are generally more physical and their behaviour is more noticeable. Girls often say nasty things, which end up disrupting the lesson just as much as the boys, as other children get upset and can’t focus on their work. They are usually the ones who refuse to comply with instructions." Some staff had noticed girls’ behaviour worsening.” A teaching assistant from Weston-super-Mare said: “Girls are definitely getting more violent, with gangs of girls in school who are getting worse than the gangs of boys.” The ATL annual conference in Liverpool on Monday is due to debate a motion expressing concern at increasing numbers of girls being excluded from secondary school.  Government figures for 2008-9 showed that boys represented 78% of the total number of permanent exclusions from schools in England. This proportion was unchanged from the year before. The ATL general secretary, Mary Bousted, said: "Staff get ground down daily by the chatting and messing around, which disrupts lessons for other pupils and takes the pleasure out of teaching. Even more worrying is the physical aggression, most often among boys but also among some girls, which puts other pupils and staff at risk. Schools need to have firm and consistent discipline policies and work with parents to keep schools and colleges safe places for pupils and staff alike." The education bill, now going through the Commons, will give teachers the right to search pupils for banned items and will remove the requirement to give parents a day’s notice of detention. The education secretary, Michael Gove, said the measures in the bill would “restore discipline” in the classroom.

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

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

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

Read the following passage and choose the best answer (A, B, C, D):
Modern society has given significant attention to the promises of the digital economy over the past decade. But it has given little attention to its negative environmental footprint. Our smartphones rely on rare earth metals, and cloud computing, data centers, artificial intelligence and cryptocurrencies consume large amounts of electricity, often sourced from coal-fired power plants. These are crucial blind spots we must address if we hope to capture the full potential of the digital economy. Without urgent system-wide actions, the digital economy and green economy will be incompatible with each other and could lead to more greenhouse gas emissions, accelerate climate change and pose great threats to humanity. The world’s data centers-the storehouses for enormous quantities of information - consume about three percent of the global electricity supply (more than the entire United Kingdom), and produce two percent of global greenhouse gas emissions-roughly the same as global air travel. A report by Greenpeace East Asia and the North China Electric Power University found that China’s data centers produced 99 million tonnes of carbon dioxide in 2018, the equivalent of about 21 million cars driven for one year. Greenhouse gases aren’t the only type of pollution to be concerned about.Electronic waste (e-waste), which is a byproduct of data center activities, accounts for two percent of solid waste and 70 percent of toxic waste in the United States. Globally, the world produces as much as 50 million tonnes of electronic e-waste a year, worth over US$62.5 billion and more than the GDP of most countries. Only 20 percent of this e-waste is recycled. The world and its intractable challenges are not linear-everything connects to everything else. We must raise awareness about these major blind spots, embrace systems leadership (leading across boundaries), boost circular economy ideas (decoupling economic activity from the consumption of finite resources), leverage an eco-economics approach (an environmentally sustainable economy) and encourage policy-makers to explore the interrelationships between government-wide, system-wide and societal results. We must also consider collective problem-solving by bringing together diverse perspectives from both the Global North and the Global South. We should take an inventory of the global and local damages caused by electronic devices, platforms and data systems, and frame issues about the digital economy and its environmental impact in broad societal terms.
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):
Stonehenge, the prehistoric stone circle in southern England, is one of the most distinctive and mysterious monuments in the world. The monument, which attracted more than one and a half million visitors last year, is thought to be up to 5,000 years old, and the heaviest stone weighs 38 tons. No one really knows how the stones got there, or the reason they look the way they do – but a piece removed from one of the stones six decades ago could bring some answers. At first glance, the new “discovery” - a cylinder of rock - might look unremarkable. But for Lewis and Robin Phillips, it meant one thing: their dad, Robert. In 1958, Robert Phillips worked on a major restoration project commissioned by the British government. The goal was to make the monument safer, and help historians better understand what Stonehenge was and why it was there. The team drilled through the largest of the sarsen rocks, removing three stone cores. Robert Phillips was gifted one as a souvenir. At the time, the core sample was considered to be “waste material,” Lewis said. “I think that the standards of the day, in conservation, were a bit different to what they are now,” Robert added. Six decades later, Robert - who’s now in his 90s - asked his sons to return the “waste material.” But what had become a family heirloom for the Phillips’ was “the Holy Grail” of Stonehenge for geologists, according to Susan Greaney, an archaeologist at English Heritage. “When the Phillips family first got in touch with us, we had no idea that this existed,” Greaney said. “We’d just assumed that they’d been thrown away.” In 1958, samples like this couldn’t provide much information - but now, Greaney added, it can help archaeologists understand where the stones were from and how they were transported. It could even provide clues to one of the biggest questions: why move all these rocks to one location? Right now, “we don’t know” is the answer to that, Greaney said. "We think this is a prehistoric temple. It’s aligned with the movements of the sun, so we think it’s some kind of ceremonial space. But exactly what the stones mean, why they built them in this way and set them up in the way we see today, there are lots of mysteries about Stonehenge that we have yet to get to the bottom of.

The United States Department of Education describes “giftedness” as exceptionally advanced performance or the potential for outstanding performance in intellectual, creative leadership, artistic, or specific academic fields. Children who demonstrate outstanding talents come from all social, cultural, and economic groups.
Educators believe that gifted students require special education services because their learning needs differ significantly from those of the general population. They learn more rapidly and are able to understand more abstract and complex ideas. They are also able to transform existing knowledge into new and useful forms, and to create new knowledge recognized for its originality, complexity, and elegance. Special education services and facilities for gifted children may enhance these abilities. In addition, some gifted learners may require special counseling services to address social or emotional adjustment issues that are complicated by their exceptional abilities.
Many regular elementary and secondary schools in the United States offer special programs designed specifically to meet the needs of gifted students. Some schools provide specialized education programs to gifted children exclusively. These schools offer advanced education in mathematics, science, technology, the arts, or other academic disciplines. Many schools rely on intelligence tests to identify gifted students. However, most guidelines for determining giftedness recommend the use of a combination of standardized test scores, rating systems developed by individual schools, classroom observation records, and performance assessments.
Gifted children may study a specially modified curriculum or may progress through academic subjects at an accelerated pace. Acceleration involves adapting education programs so that students may progress through particular subject material quicker than usual. These modifications may take place within the regular classroom setting or they may involve changing the child’s placement in school. Some gifted children gain early entrance to kindergarten, skip grades, enter college earlier than usual, or take specific courses with older children. Ideal programs for gifted students consider the individual needs of children and offer multiple options for services. These programs generally involve both advanced course materials and acceleration.

Last week, China declared “mission accomplished” after landing a spacecraft, Chang’e-4, on the far side of the Moon. It was a remarkable endeavour. As the far side of the Moon never faces the Earth, mission control cannot communicate directly with the spacecraft, but only via an orbiting satellite. The terrain is more broken and cratered than the near side, so landing a craft is that much more difficult. Even Nasa was impressed: “a first for humanity and an impressive accomplishment!”. Yet mixed with admiration was trepidation. China, a latecomer to the space race, is now beginning to threaten the supremacy of America and Russia. But then Russia and America have long played their space exploration programmes for propaganda purposes. From the beginning, the space race was intimately bound up with the needs of the cold war. In 1957, the Soviet Union launched Sputnik, the first human craft to orbit the Earth. Four years later, Yuri Gagarin became the first man in space. Eight years later, on 21 July 1969, Neil Armstrong and Buzz Aldrin became the first humans to tread on the Moon. Their journey may have been fuelled in part by cold war desperation, but it was also an extraordinary triumph of knowledge and will, an act of the technological sublime. Once America was satisfied that the Soviet Union had been put in its place, space exploration became politically less important. As America downgraded its space ambitions, Chinese aspirations took flight. In 1992, the Chinese government approved the Shenzhou manned spaceflight programme. Eleven years later, Yang Liwei became the first Chinese astronaut in space. Fears about Chinese ambitions have been heightened by the changing context of the space race. During the cold war, America feared the Soviet Union, but was determined to thwart Moscow’s aims. Today, American apprehension stems from the worry that China’s emergence as the dominant global force cannot be checked, nor Beijing’s brutal despotism challenged. As liberal democracy frays in the west and authoritarian capitalism becomes entrenched in the east, self-doubt shapes US attitudes to China. Space exploration has long been fuelled by a mixture of humanistic dreams, technological leaps and tawdry politics. The Chang’e-4 mission is no different. How the space race will play out over the next decade, and what role China will adopt in global politics, remains uncertain. In the meantime, let us celebrate our new perspective of the dark side of the Moon.

Alzheimer's disease impairs a person's ability to recall memories, both distant and as a few hours before. Although there is no yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs. Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiment do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.
1. With what topic is this passage mainly concerned?

Read the following passage and choose the best answer (A, B, C, D):
Far from being barren wastelands, deserts are biologically rich habitats with a vast  array of animals and plants that have adapted to the harsh conditions there. Some deserts are among the planet’s last remaining areas of total wilderness. Yet more than one billion people, one-sixth of the Earth’s population, actually live in desert regions.  Deserts cover more than one fifth of the Earth’s land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. Deserts are part of a wider classification of regions called “dry lands.” These areas exist under a moisture deficit, which means they can frequently lose more moisture through evaporation than they receive from annual precipitation.  And despite the common conceptions of deserts as dry and hot, there are cold deserts as well. The largest hot desert in the world, northern Africa’s Sahara, reaches temperatures of  up to 122 degrees Fahrenheit (50 degrees Celsius) during the day. But some deserts are always cold, like the Gobi desert in Asia and the desert on the continent of Antarctica. Others are mountainous. Only about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain.  Desert animals have adapted ways to help them keep cool and use less water. Camels, for example, can go for days without food and water. Many desert animals are nocturnal, coming out only when the brutal sun has descended to hunt. Some animals, like the desert tortoise in the south-western United States, spend much of their time underground. Most desert birds are nomadic, crisscrossing the skies in search of food. Because of their very special adaptations, desert animals are extremely vulnerable to introduced predators and changes to their habitat.  Some of the world’s semi-arid regions are turning into desert at an alarming rate. This process, known as “desertification,” is not caused by drought, but usually arises from the demands of human populations that settle on the semi-arid lands to grow crops and graze animals. The pounding of the soil by the hooves of livestock may degrade the soil and encourage erosion by wind and water.
4. What is the direct cause of desertification?
