A new study shows that urbanization shifts this seasonal cue in nuanced ways, with cities in cold climates triggering earlier spring plant growth and cities in warm climates delaying it. The study also found that the urban heat island effect, the phenomenon in which cities are warmer than their surroundings, is not the only culprit behind the shift, suggesting that other aspects of urbanization, such as pollution, changes in humidity and fertilizer runoff, may also influence plants’ seasonal patterns.  Researchers analyzed millions of observations of 136 plant species across the U.S. and Europe to study how regional temperature and the local density of people-a proxy for urbanization—affect when plants sprout leaves and blossoms. Their results revealed a complex story: Separately, warmer temperatures and higher population density each spurred earlier springs. A 3.6-degree Fahrenheit increase in temperature bumped up plants’ production of leaves and flowers by about five and six days, respectively. A fourfold increase in human population density advanced flowering and leaf production dates by about three days. But the team found that when these two factors worked together, local temperature had an outsized influence. In cold regions—areas with an average November-to-May temperature of about 18 degrees-plants produced leaves and flowers about 20 days earlier in locations with about 26,000 people per square mile, compared with equally frigid wildland. When an area’s average November-to-May temperature jumped to 68, however, leaves and flowers appeared four and six days later, respectively, in locations with about 26,000 people per square mile, compared with equally balmy wildland. In New York, for example, plants are likely sprouting leaves about 9.5 days earlier and blossoms eight days earlier than uninhabited regions with the same temperature. Jacksonville, in contrast, is likely pushing leaf production later by about one day and flowers by about half a day, with leaves appearing two days later and flowers a day later in Houston.  Even after accounting for urban heat islands, the team’s models revealed cities significantly affect plants’ springtime growth. “Not only are there other things going on, but they actually matter quite a lot,” said study co-author Brian Stucky, Florida Museum research scientist. Plants may not be the only organisms affected by seasonal shifts, he added. “Seasons are such a big part of our lives. We define our world around seasonal things. Those rhythms are what we think of as the normal way the world works.”

The United States has had approximately a thousand lights as well as light towers,  range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Most of the lights in the United States have been built and maintained by the Coast Guard. As navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership to other parties. The first navigational lights in the New World were probably lanterns hung at harbor entrances. The first lighthouse was put up by the Massachusetts Bay Colony In 1766 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by light dues levied on ships, the original beacon was blown up in 1776. By then there were only a dozen or so true lighthouses in the colonies. Little over a century later, there were 700 lighthouses.  The first eight erected on the West Coast in the 1850’s featured the same basic New England design: a Cape Cod dwelling with the tower rising from the center or standing close by. In New England and elsewhere, though, lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were built on rocky eminences, enormous towers were not the rule. Some were made of stone and brick, others of wood or metal. Some stood on pilings or stilts: some were fastened to rock with iron rods. Farther south, from Maryland through the Florida Keys, the coast was low and sandy. It was often necessary to build tall towers there - massive structures like the majestic Cape Hatteras, North Carolina lighthouse, which was lit in 1870. At 190 feet, it is the tallest brick lighthouse in the country. Notwithstanding differences in appearance and construction, most American lighthouses shared several features: a light, living quarters, and sometimes a bell (or, later, a foghorn). They also had something else in common: a keeper and, usually, the keeper’s family. The keeper’s essential task was trimming the lantern Nick in order to maintain a steady bright flame. The earliest keepers came from every walk of life-they were seamen. Farmers, mechanics, rough mill hands-and appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouses was taken over in 1852 by the United States Lighthouse 803rd, an agency of the Treasury Department, the keeper corps gradually became highly professional.

Vocational training in the UK is intended to give people the skills and knowledge they  need to perform a particular job, and involves practical instruction as well as theory. Most vocational training takes place not in universities but in colleges of further education and in colleges specializing in art, accountancy, etc. some secondary schools now also offer an introduction to vocational training.  NVQs (National Vocational Qualifications) are qualifications that can be obtained by people already working in a particular industry. Colleges of further education run courses to provide a theoretical background. NVQs are awarded on the basis of practical work, spoken and written test, and coursework. There are five levels, from Foundation to Management. Since 1992 many students in schools and colleges have been working for GNVQs (General National Vocational Qualifications), as an alternative to GCSEs and A levels. GNVQs cover similar areas to NVQs and are intended as introductions to a particular field of work and the skills required. Students can choose from over 500 subjects. At the lowest of its three levels foundation, a GNVQ is equivalent to a GCSE and from 2002 they are being replaced by new vocational GCSEs.  In the US there are no national qualifications like NVQs, though some professional organizations decide on their own qualifications and some of these have become widely accepted. Much vocational training is done by private institutions which are sometimes called proprietary schools. Although many of these are good, in general they have a bad reputation. This is partly because there are no controls over who can operate such a school. Some proprietary schools try to get as many students as possible, including some who will probably not be able to complete their training.  Most US secondary schools programs do not provide a choice between an academic and a practical track (a program of study), but most do give students an opportunity to take some practical or vocational classes. Large school districts may have magnet schools, schools that attract students with certain interests, and some of these may have a large choice of vocational courses.

The number of people accessing the State’s and community’s priority policies and  programmes is increasing, said Minister of Labour, Invalids and Social Affairs Dao Ngoc Dung. Vietnam has around 6.2 million people over the age of two with disabilities, making up 7.06 per cent of the country’s population. Of those, 28 per cent are severely disabled, 58 per cent female, 28 per cent children and 10 per cent living in poverty. Most live in rural areas and many are victims of Agent Orange.  Minister Dung said in the past, the State, the Party and Vietnamese people had paid much care to people with disability. Vietnam ratified the United Nations’ Convention on the Rights of People with Disability in 2014. In March this year, the country ratified the International Labour Organisation’s Convention 159 about jobs for people with disability. It strongly confirmed Vietnam’s commitment ensuring the disabled would not be discriminated at work.  Last month, the Secretariat Committee issued the Instruction 39 about the Party’s leading work on affairs related to people with disability. The National Assembly later ratified the amended Law on Labour with many adjustments relating to disabled people. Dung said that every year, millions of disabled people receive an allowance from the State and all of provinces and cities had rehabilitation centres. Attending the event, Truong Thi Mai, head of the Party Central Committee’s Commission for Mass Mobilisation, said besides the achievements, Vietnam still sees many obstacles. Infrastructure is still limited demand for people with disability and many live below the poverty line depending heavily on their families.  Mai asked organisations to improve education to raise people’s awareness of the meaning of supportive work to people with disability. This year, more than VNĐ17 trillion (US$735.4 million) from the State budget was allocated to provinces and cities to implement policies for people with disability, according to the Ministry of Labour, Invalids and Social Affairs.  The Ministry of Planning and Investment on Thursday launched the programme “White stick for Vietnamese visual impaired people”. Its aim is to present one million white sticks to visually impaired people across the country. Training to use the device will also be provided. Minister of Planning and Investment Nguyen Chi Dung said the ministry will listen to disabled people’s demands and wishes and put them into its policies. Deputy chairwoman of the National Assembly Tong Thi Phong said Vietnam has committed to developing socioeconomy, taking care of social equality and improving social management ability.

In the 1930s, a lot of people in the USA were out of work. Among these people was a man named Alfred Butts. He always had an interest in word games and so, to fill his time, he planned a game which he called “Lexico”. However, he was not completely satisfied with the game, so he made a number of changes to it and, in time, changed its name from “Lexico” to “Alph” and then to “Criss Cross”. He wanted to make some money from his new game but he didn’t have any real commercial success. In 1939, Butts happened to meet a man called Jim Brunot who showed an interest in the new game. The two men worked together on developing the game and in 1948 it was offered for sale in the United States under its new name - “Scrabble”. At first, it didn’t sell very well. In the first year it sold just 2,250 sets and by 1951 it had only reached 8,500 sets a year. Then, in 1952 the manager of Macy’s department store in New York, Jack Strauss, happened to play “Scrabble” while he was on holiday. He thought it was a wonderful game and, when he went back to work after his holiday, he insisted that Macy’s should stock the game and make an effort to call the public’s attention to it. As a result, “Scrabble” became a big success in the United States and it soon spread to Australia and then to other English-speaking countries

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.

The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.

Read the following passage and choose the best answer (A, B, C, D):
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.

Read the following passage and choose the best answer (A, B, C, D)
Gender inequality remains an everyday reality for the world’s women and girls. It can begin right at the moment of birth and continue throughout the course of a woman’s life. Despite critical advances over the course of recent history, women in all countries and across all socioeconomic levels in society can face various forms of unfair treatment, including discrimination, harassment, domestic violence and sexual abuse. Other forms of abuse that are particularly prevalent in certain countries or cultural contexts include forced marriage, honor killings, deprivation of education, denial of land and property rights, and lack of access to work and to health care. Women may experience human rights abuses at different points in their working lives, including during recruitment, hiring, promotion and termination processes, as well as in daily interactions with colleagues and supervisors. Outside of the workplace, women are often particularly vulnerable to the social and environmental impacts of business activities. For example, in many developing countries, women and girls are primarily responsible for fetching and hauling water. When company operations contaminate local sources, it is they  who carry the burden of walking, often for hours, to the nearest substitute, which can prevent them from working or going to school. According to the UN Entity for Gender Equality and the Empowerment of Women, gender “refers to the social attributes and opportunities associated with being male and female and the relationships between women and men and girls and boys, as well as the relations between women and those between men. These attributes, opportunities and relationships are socially constructed and are learned through socialization processes.” Furthermore, gender equality “refers to the equal rights, responsibilities and opportunities of women and men and girls and boys. Equality does not mean that women and men will become the same but that women’s and men’s rights, responsibilities and opportunities will not depend on whether they are born male or female.” Women and girls comprise half of the planet’s population; their empowerment is essential in expanding economic growth and promoting social development in a sustainable way. Evidence from around the world shows that gender equality advancements have a ripple effect on all areas of sustainable development, from reducing poverty, hunger and even carbon emissions to enhancing the health, well-being and education of entire families, communities and countries. In fact, “Equality between women and men is seen both as a human rights issue and as a precondition for, and indicator of, sustainable people-centered development.”

Frenchman Edouard de Laboulaye first proposed the idea of a monument for the United States in 1865. Ten years later sculptor Frederic Auguste Bartholdi was commissioned to design a sculpture with 1876 in mind for completion, to commemorate the centennial of the American Declaration of Independence. The Statue was named “Liberty Enlightening the World” and was a joint effort between America and France. It was agreed that the American people were to build the pedestal, and the French people were responsible for the Statue and its assembly here in the United States. However, lack of funds was a problem on both sides of the Atlantic Ocean. In France, public fees, various forms of entertainment, and a lottery were among the methods used to raise funds. In the United States, benefit theatrical events, art exhibitions, auctions and prizefights assisted in providing needed funds. Poet Emma Lazarus wrote her famous sonnet “The New Colossus” in 1883 for the art and literary auction to raise funds for the Statue’s pedestal. Meanwhile in France, Bartholdi required the assistance of an engineer to address structural issues associated with designing such a colossal copper sculpture. Alexandre Gustave Eiffel (designer of the Eiffel Tower) was commissioned to design the massive iron pylon and secondary skeletal framework which allows the Statue’s copper skin to move independently yet stand upright Back in America, fundraising for the pedestal was going particularly slowly, so Joseph Pulitzer opened up the editorial pages of his newspaper, “The World,” to support the fund raising effort. Pulitzer used his newspaper to criticize both the rich who had failed to finance the pedestal construction and the middle class who were content to rely upon the wealthy to provide the funds. Pulitzer’s campaign of harsh criticism was successful in motivating the people of America to donate. Architect Richard Morris Hunt designed the Statue of Liberty’s granite pedestal in 1884, donating his fee to help fund the Statue. Financing for the pedestal was completed in August 1885, and pedestal construction was finished in April 1886. The Statue was completed in France in July 1884 and arrived in New York Harbor in June 1885 onboard the French frigate “Isere.” In transit, the Statue was reduced to 350 individual pieces and packed in 214 crates. The Statue was reassembled on her new pedestal in four months’ time. On October 28, 1886, President Grover Cleveland oversaw the dedication of the Statue of Liberty in front of thousands of spectators. She was a centennial gift ten years late

Read the following passage and choose the best answer (A, B, C, D):
What results in good health and longevity? It’s good genes, good lifestyle and good luck. But since we can’t choose our parents, or know what fate holds in store for us, we must treat lifestyle with tender, loving care. Now, a report “Circulation” proves that a sound lifestyle adds 12 to 14 more years to life. For instance, a woman, aged 50, who follows these lifestyle rules can expect to live to 93 years. This compares to a woman who indulges in an unhealthy lifestyle and dies at 79. In men, the increase in longevity from a healthy lifestyle is from 76 to 88 years. In the general population, the U.S. spends more money on health care than any other country. So why are so many people in North America suffering from ill health? It is quite apparent that the epidemic of obesity, type 2 diabetes and heart attack will continue to be the big killers. At the moment there is little evidence this battle is being won. But a study that followed both staff and students at the University of Liverpool shows it’s not an impossible dream. In its first experiment, female diners were randomly divided to receive either a small or large quiche for lunch. The next day, the same group were all allowed to serve themselves any portion they desired. Researchers discovered the ones who had been served the smaller portion, tended to choose the smaller portion. A second experiment tested male diners and it produced the same result. In the third experiment both sexes were included, but it was done one week later. This time diners were asked to look at various photos of portion size and asked which looked normal. Those who were previously given the smaller portions considered the smaller ones normal.  These studies showed that it is possible to shift people from what they think is a normal portion to what is actually the proper amount to eat. And that the perception of what is normal lasts at least to one week later. Remember, a voyage of a thousand miles begins with the first step. The same philosophy applies to longevity. So, gradually incorporate one thing at a time into your lifestyle. Don’t forget the importance of smaller portions, add more fruits and vegetables, buy a pedometer to check the number of steps taken each day, and to measure your progress, step on the scale every day

A massage is relaxing, and makes you feel great, but did you know that it's also good for you? That's what doctors are now saying. Massage relieves pain and anxiety, eases depression and speeds up recovery from medical problems.
Research has shown that people of all ages benefit from touch. Premature infants who are held develop faster than those left alone, and healthy babies who get a lot of physical contact cry less and sleep better. Researchers are not sure why this occurs but they have also found out that touch can slow heart rate, lower blood pressure and increase levels of seratonin, the brain chemical that is linked to well-being. It also decreases levels of the stress hormone cortisol, and this in turn increases your resistance to illness.
Massage also speeds up healing. Bone-marrow transplant patients who were given massages had better neurological function than those who weren't. Furthermore, massage reduced pain by 37% in patients with chronic muscle aches.
Giving someone a massage may be as good as getting one. A study conducted by the university of Miami found that mothers suffering from depression felt better after massaging their infants. In that same study, elderly volunteers who massaged infants reported feeling less anxious and depressed.
It even works when you do it yourself; 43% of headache sufferers reported getting relief after massaging their temples and neck and smokers who were taught self-massage while trying to quit felt less anxiety and smoked less.

Read the following passage and choose the best answer (A, B, C, D):
The world is losing languages at an alarming rate. Michael Krauss suggested that of the approximately 6,000 human languages alive today, only 350 to 500 are safe from extinction. Some linguists estimate that a language dies every two weeks or so. At the current rate, by 2100, about 2,500 native languages could disappear. Languages become extinct for many reasons. Through imperialism, colonizers impose their languages on colonies. Some politicians believe multilingualism will fragment national interests. Thus they prohibit education in all but the national language. Another reason for language death is the spread of more powerful languages. In the world today, several languages, including English, are so dominant in commerce, science, and education, that languages with fewer speakers have trouble competing. Although in the past, governments have been one of the primary causes of language death, many have now become champions of preserving endangered languages and have had some significant successes. Two outstanding examples are the revival of Hebrew and Irish. Hebrew was considered a dead language, like Latin, but is now the national language of Israel. Irish was not dead, but severely threatened by English when the government of Ireland began its rescue immediately after the establishment of the Irish Free State in 1922. All students in public schools must now take some classes in Irish and there are Irish programs in major media, such as television and radio. According to the Irish government, approximately 37% of the population of Ireland now speaks Irish. One of the largest programs to revive languages, Documenting Endangered Languages (DEL), is being conducted by three U.S. government agencies: the National Science Foundation, the National Endowment for the Humanities, and the National Museum of Natural History. Researchers funded by these agencies are recording interviews with the mostly elderly people who still speak the languages. Analyses of these interviews will help linguists publish dictionaries and grammars of the languages. Eventually, linguists hope to establish language-training programs where younger people can learn the languages, carrying them on into the future. The linguists participating in DEL defend spending millions of dollars to preserve dying languages. They point out that when a language dies, humanity loses all of the knowledge of the world that that culture held. Traditional healers in rural areas have given scientists important leads in finding new medicines; aspirin is an example of these. But one of the most common reasons given by these researchers is that studying languages gives us insight into the radically different way humans organize their world. David Lightfoot, an official at the National Science foundation, gives the example of Guguyimadjir, and Australian aboriginal language, in which there are no words for “right” or left,” only for “north,” “south,” “east,” and “west.” Many researchers are optimistic that the efforts to save dying languages will succeed, at least in part. Bruce L. Cole, Chairman of the National Endowment for the Humanities, said, “Not only is this a time of great potential loss, it is also a moment for enormous potential gain. In this modern age of computers and our growing technological capabilities, we can preserve, assemble, analyze, and understand unprecedented riches of linguistic and cultural information.”
3. It can be inferred from paragraph 3 that ______
