Read the passage below and choose one correct answer for each question.

Movements and gestures by the hands, arms, legs, and other parts of the body and face are the most pervasive types of nonverbal messages and the most difficult to control. It is estimated that there are over 200.000 physical signs capable of stimulating meaning in another person. For example, there are 23 distinct eyebrow movements, each capable of stimulating a different meaning. Humans express attitudes toward themselves and vividly through body movements and postures. Body movements express true messages about feelings that cannot be masked. Because such avenues of communication are visual, they travel much farther than spoken words and are unaffected by the presence of noise that interrupt, or cancels out speech. People communicate by the way they walk, stand, and sit. We tend to be more relaxed with friends or when addressing those of lower status. Body orientation also indicates status or liking of the other individual. More direct orientation is related to a more positive attitude. Body movements and postures alone have no exact meaning, but they can greatly support or reject the spoken word. If these two means of communication are dichotomized and contradict each other, some result will be a disordered image and most often the nonverbal will dominate.

According to the text, body movements cannot express ________.

“What we’re seeing in Australia, in a completely different environment, are fires that are approaching or even exceeding the magnitude of things that we only saw in the most remote forested regions in the world,” said Ross Bradstock, the director of the Center for Environmental Risk Management of Bushfires at the University of Wollongong in New South Wales. The numbers from Australia dwarf those from some of the most high-profile fires in recent years. The bushfires in southeastern Australia this season have burned about eight times as much land as the 2018 fires in California, which covered nearly two million acres and were the worst in that state’s recorded history.  In Australia’s history, most bad fire seasons have coincided with the warming of an El Niño pattern. But that is not the case this time, showing how much this season stands out and the danger the country faces with more unpredictable weather patterns in the future. “While scientists have long predicted that climate change would bring longer and more intense fire seasons”, Dr. Bradstock said, “Under his projections, Australia would not have seen this kind of devastation for another 40 to 50 years”.  “I guess I’m as shocked as anyone about what’s unfolding and, probably, like everyone else who’s involved and affected, we’ll very quickly recalibrate thinking about what we’re doing,” he said. Recalibrating means expecting these phenomenal fires to continue to occur, particularly as Australia’s drought shows few signs of ending and temperatures are expected to continue to climb after the warmest decade on record.  “We would be extremely foolish, given all the evidence and the magnitude of this event, to just laugh it off as a one-off phenomenon,” Dr. Bradstock said. “I think we have to get ready to deal with a season like this again in the not-too-distant future.”

Nikola Tesla led an extraordinary life. He is a man who came from nowhere yet became world famous; claimed to be devoted solely to discovery but relished the role of a showman; attracted the attention of many women but never married; and generated ideas that transformed daily life and created multiple fortunes but died nearly penniless. In the popular imagination, Tesla played the part of a mad scientist. He claimed that he had developed a motor that ran on cosmic rays; that he was working on a new nonEinsteinian physics that would supply a new form of energy; that he had discovered a new technique for photographing thoughts; and that he had developed a new ray, alternately labeled the death ray and the peace ray, with vastly greater military potential than Nobel’s munitions. His money long gone, Tesla spent his later years moving from place to place, leaving behind unpaid bills. Eventually, he settled in at a New York hotel. Always living alone, he frequented the local park, where he was regularly seen feeding and tending to the pigeons,  with which he claimed to share a special affinity. On the morning of Jan. 7, 1943, he was found dead in his room by a hotel maid at age 86. Today the name Tesla is still very much in circulation. The airport in Belgrade bears his name, as does the world’s best-known electric car, and the magnetic field strength of MRI scanners is measured in Teslas. Tesla was a real-life Prometheus: the mythical Greek titan who raided heaven to bring fire to mankind, yet in punishment was chained to a rock where each day an eagle ate his liver.

New data from the New York Fed highlights how the job situation for recent  graduates is worsening. While the rest of the labor market trends favorably, fresh graduates are more likely to be unemployed than the base U.S. working population. That has not happened before in the New York Fed data going back to 1990.  While the unemployment rate for all college graduates aged up to 65 is trending lower — currently near its lowest level of this current economic cycle — the market for recent college graduates is bucking the overall trend. With the backdrop of a robust U.S. labor market, this is “an important and worrisome trend to watch because it never dropped to prior cycle lows,” DataTrek’s Jessica Rabe wrote in a note. “Even though those who have graduated from college typically get hired before less educated workers.”  The rates are calculated as a 12-month moving average. Recent college graduates are defined as those between the ages of 22 and 27, with a bachelor’s degree or higher. The unemployment rate for recent college graduates has been inching upwards, from 3.8% in May to 4% in September. In contrast, the unemployment rate for overall workers was 3.6% in September.  Fresh graduates are having a hard time because of the lack of experience and relevant education, according to Brusuelas. “There’s some concern about the unemployment rate … [but] that may have more to do with the level of experience and difficulties in finding entry level work right now for the educated class.” Moody’s Analytics Chief Economist Mark Zandi previously told Yahoo Finance that the trend also “likely reflects in part greater caution by businesses given the slowing economy and uncertainty created by the trade war.”

Can a performance go viral? Ben Platt’s should. As the title character in Dear Evan Hansen, the new musical from Benj Pasek and Justin Paul, he offers acting so precise yet so painfully lucid that it should overwhelm the operating systems by which most contemporary musicals operate. Platt’s gestures, his expressions, his phrasing, even his vocal range – which is impressive but tends to thin out toward the top notes – all combine to communicate the fretfulness, uncertainty and timorous goodness that define his character. He plays Evan, a friendless high school senior terrified of life, the universe, everything. His harried single mother, Heidi, (Rachel Bay Jones) tells him, “You can’t succeed if you never try.” Evan nods, but you can that he believes more strongly in the corollary: “If you don’t try, you can’t fail.” A therapist has instructed him to write pep-talk letters to himself. On the first day of school, one of them falls into the hands of Connor Murphy (Mike Faist), another outcast with drug problems and a look a peer describes as “school shooter chic”. When Connor kills himself, his parents find the letter and mistakenly believe that Evan was a friend to their son. At first this attention panics Evan, but he soon accepts the role and even briefly becomes an internet sensation. Often he is tempted to tell Connor’s family the truth, but he fears disappointing them and sacrificing his newfound confidence Watching Dear Evan Hansen, one often thinks of Next to Normal, another Second Stage show about a mentally distressed protagonist. But with its tuneful pop score and teenage protagonist, Dear Evan Hansen is a gentler affair, even as it takes occasional pains not to oversentimentalize the material. When Evan presents a surprisingly rosy picture of her brother, his sister Zoe (Laura Dreyfuss) sings, “Don’t say it wasn’t true/ That you were not the monster/ That I knew.” Near the play’s end, Platt positively glistens with sweat and spit and tears. Yet one never has the sense of an actor deliberately winding himself up to deliver a visceral performance. There’s obvious care taken in the way he offers Evan’s cringing smile, his swallowed laugh, his habit of pulling at his clothes as though searching for someone to hold onto. But all of these details feel lived, organic, unrehearsed. And Platt’s ability to convey emotion through song is simply superb and often deeply heartrending.

Social networking sites such as Facebook and MySpace do not help you make more  genuine close friends, according to a survey by researchers who studied how the websites are changing the nature of friendship networks. Although social networking on the internet helps people to collect hundreds or even thousands of acquaintances, the researchers believe that face to face contact is nearly always necessary to form truly close friendships.  “Although the numbers of friends people have on these sites can be massive, the actual number of close friends is approximately the same in the face to face real world,” said psychologist Will Reader, from Sheffield Hallam University. Social networking websites such as Facebook, Bebo and MySpace have taken off rapidly in recent years. Facebook was launched initially in 2004 for Harvard University members but has since expanded to more than 34 million users worldwide. MySpace, which was set up in 2003, has more than 200 million users and was bought by Rupert Murdoch’s News Corporation in 2005 for $580m (£285m). Previous research has suggested that a person’s conventional friendship group consists of around 150 people, with five very close friends but larger numbers of people whom we keep in touch with less regularly. This figure is so consistent that scientists have suggested it is determined by the cognitive constraints of keeping up with large numbers of people. But Dr. Reader and his team have found that social networking sites do allow people to stretch this figure. The team asked more than 200 people to fill in questionnaires about their online networking, asking for example how many online friends they had, how many of these were close friends and how many they had met face to face. The team found that although the sites allowed contact with hundreds of acquaintances, as with conventional friendship networks, people tend to have around five close friends. Ninety per cent of contacts whom the subjects regarded as close friends were people they had met face to face. “People see face to face contact as being absolutely imperative in forming close friendships,” added Dr. Reader. He told the British Association Festival of Science in York that social networking sites allow people to broaden their list of nodding acquaintances because staying in touch online is easy. “What social network sites can do is decrease the cost of maintaining and forming these social networks because we can post information to multiple people,” he said.  But to develop a real friendship we need to see that the other person is trustworthy, said Dr. Reader. "What we need is to be absolutely sure that a person is really going to invest in us, is really going to be there for us when we need them … It’s very easy to be deceptive on the internet."

The Nobel Peace Prize is awarded annually and the first woman to win this prize was Baroness Bertha Felicie Sophie von Suttner in 1905. In fact, her work inspired creation of the Prize. The first American woman to win the prize was Jane Addams, in 1931. However, Addams is best known as the founder of Hull House.
Jane Addams was born in 1860, into a wealthy family. She was one of a small number of women in her generation to graduate from college. Her commitment to improving the lives of those around her led her to work for social reform and world peace. In the 1880s Jane Addams travelled to Europe. While she was in London, she visited a “settlement house” called Toynbee Hall. Inspired by Toynbee Hall, Addams and her friends, Ellen Gates Starr, opened Hull House in a neighborhood of slums in Chicago in 1899. Hull House provided a day care center for children of working mothers, a community kitchen, and visiting nurses. Addams and her staff gave classes in English literacy, art and other subjects. Hull House also became a meeting place for clubs and labor unions. Most of the people who worked with Addams in Hull House were well educated, middle-class women. Hull House gave them an opportunity to use their education and it provided a training ground for careers in social work.
Before World War I, Addams was probably the most beloved woman in America. In a newspaper poll that asked, “Who among our contemporaries are of the most value to the community?” Jane Addams was rated second, after Thomas Edison. When she opposed America’s involvement in World War I, however, newspaper editors called her a traitor and a fool, but she never changed her mind. Jane Addams was a strong champion of several other causes. Until 1920, American women could not vote. Addams joined in the movement for women’s suffrage and was a 7 vice president of the National American Woman Suffrage Association. She was a founding member of the National Association for the Advancement of Colored People (NAACP), and was president of the Women’s International League for Peace and Freedom. Her reputation was gradually restored during the last years of her life. She died of cancer in 1935.

According to the passage, Jane Addams’ reputation was damaged when she .

Read the following passage and choose the best answer (A, B, C, D):
The temperature of the earth is rising at nearly twice the rate it was 50 years ago. This rapid rate and pattern of warming, scientists have concluded, cannot be explained by natural cycles alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. To come to a conclusion on climate change, the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists. One of the first things the IPCC learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture, especially from the digestive systems of grazing animals, nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2. Different greenhouse gases have very different heat-trapping abilities. Some of them can even trap more heat than CO2. A molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2. Other gases, such as chlorofluorocarbons, or CFCs, which have been banned in much of the world because they also degrade the ozone layer, have heat-trapping potential thousands of times greater than CO2. But because their concentrations are much lower than CO2, none of these gases adds as much warmth to the atmosphere as CO2 does. In order to understand the effects of all the gases together, scientists tend to talk about all greenhouse gases in terms of the equivalent amount of CO2. Since 1990, yearly emissions have gone up by about 6 billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase.

Green-space facilities are contributing to an important extent to the quality of the urban environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present, it is generally accepted, although more as a self-evident statement than on the base of a closely-reasoned scientific proof. The recognition of the importance of green-spaces in the urban environment is a first step on the right way; this does not mean, however, that sufficient details are known about the functions of green-space in towns and about the way in which the inhabitants are using these spaces. As to this rather complex subject I shall, within the scope of this lecture, enter into one aspect only, namely the recreative function of green-space facilities. The theoretical separation of living, working, traffic and recreation which for many years has been used in town-and-country planning, has in my opinion resulted in disproportionate attention for forms of recreation far from home, whereas there was relatively little attention for improvement of recreative possibilities in the direct neighbourhood of the home. We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working, is used for activities as possible, and the design of these has to be such that more obligatory activities can also have a recreative aspect. The very best standard of living is nothing if it is not possible to take a pleasant walk in the district, if the children cannot be allowed to play in the streets, because the risks of traffic are too great, if during shopping you can nowhere find a spot for enjoying for a moment the nice weather, in short, if you only feel yourself at home after the street-door of you house is closed after you.

Coal, oil and gas get more than $370bn a year in support, compared with $100bn for renewables, the International Institute for Sustainable Development (IISD) report found. Just 10-30% of the fossil fuel subsidies would pay for a global transition to clean energy, the IISD said. Ending fossil fuel subsidies has long been seen as vital to tackling the climate emergency, with the G20 nations pledging in 2009 to phase them out, but progress has been limited. The new analysis shows how redirecting some of the fossil fuel subsidies could decisively tip the balance in favour of green energy, making it the cheapest electricity available and instigating a rapid global rollout. The transition from polluting fossil fuels to clean energy is already under way. Annual investment in renewables has been greater than that in fossil fuel electricity generation since 2008 and new renewable capacity has exceeded fossil fuel power each year since 2014. But progress is slow compared with the urgency required, said Bridle. “There is no question that renewables can power the energy system,” he said. “The question now is can we transit quickly enough away from fuels like coal, and subsidy reform is a very obvious step towards that.  Reform of fossil fuel subsidies could have a significant impact on global heating. An earlier IISD study of 20 countries with large fossil fuel subsidies found that a 30% swap to renewables would lead to emissions reductions of between 11% and 18%. Most experts define fossil fuel subsidies as financial or tax support for those buying fuel or the companies producing it. The IMF also includes the cost of the damage fossil fuel burning causes to climate and health, leading to an estimate of $5.2tn of fossil fuel subsidies in 2017, or $10m a minute. Ending the subsidies would cut global emissions by about a quarter, the IMF estimates, and halve the number of early deaths from fossil fuel air pollution. Bridle said funding fossil fuel subsidies was “madness”, but said ending them could cause short-term price rises and political difficulties, as the benefits of lower costs in the future and reduced air pollution are less obvious. “There are political problems but it is worth persevering because the prize is so big,” he said. “You have to bring people along with you.” Gençsü said governments must ensure that the most vulnerable people were not adversely affected by changes.

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.

In the United States, presidential elections are held in years evenly divisible by four (1888, 1900, 1964, etc.). Since 1840, American presidents elected in years ending with zero have died in office, with one exception. William H. Harrison, the man who served the shortest term, died of pneumonia only several weeks after his inauguration.
Abraham Lincoln was one of four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James Garfield, a former Union army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn’t give a job. While in his second term of office (1901), William McKinley, another Ohioan, attended the Pan-American Exposition in Buffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. John F. Kennedy was assassinated in 1963 in Dallas only three years after his election.
Three years after his election in 1920, Warren G, Harding died in office. Although it was never proved, many believe he was poisoned. Franklin Roosevelt was elected four times (1932, 1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and eventually died of the illness in 1945.
Ronald Reagan, who was elected in 1980 and reelected four years later, suffered an assassination attempt but did not succumb to the assassin’s bullets. He was the first to break the long chain of unfortunate events. Will the candidate in the election of 2020 also be as lucky?

Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15–20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20 years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent. Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam’s labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.

Foot racing is a popular activity in the United States. It is seen not only as a competitive sport but also as a way to exercise, to enjoy the camaraderie of like-minded people, and to donate money to a good cause. Though serious runners may spend months training to compete, other runners and walkers might not train at all. Those not competing to win might run in an effort to beat their own time or simply to enjoy the fun and exercise. People of all ages, from those of less than one year (who may be pushed in strollers) to those in their eighties, enter into this sport. The races are held on city streets, on college campuses, through parks, and in suburban areas, and they are commonly 5 to 10 kilometers in length.
The largest foot race in the world is the 12-kilometer Bay to Breakers race that is held in San Francisco every spring. This race begins on the east side of the city near San Francisco Bay and ends on the west side at the Pacific Ocean. There may be 80,000 or more people running in this race through the streets and hills of San Francisco. In the front are the serious runners who compete to win and who might finish in as little as 34 minutes. Behind them are the thousands who take several hours to finish. In the back of the race are those who dress in costumes and come just for fun. One year there was a group of men who dressed like Elvis Presley, and another group consisted of firefighters who were tied together in a long line and who were carrying a fire hose. There was even a bridal party, in which the bride was dressed in a long white gown and the groom wore a tuxedo. The bride and groom threw flowers to bystanders, and they were actually married at some point along the route.

Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste.
Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool

and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators.
Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars.
Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam.
