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

There are three valid arguments to support the preservation of endangered species. An aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture, attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world.
Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us.
Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

Herb Hamrol, 103, is among a handful of survivors of the 1906 San Francisco earthquake. Today marks the 100th anniversary of San Francisco’s great earthquake and fire. As the local newspaper Contra Costa Times observes, San Francisco has been “struggling with the difference between commemoration and celebration” leading up to the centennial. The city’s mayor, Gavin Newsom, has acknowledged that the 1906 earthquake was an “awkward” event to mark. Perhaps curiously, along with various exhibitions and lectures, more than one attempt has been made to capture the spirit of the anniversary in dance. The Walnut Creek Diablo Ballet company has produced “Earthquake”, which its creators stress is not just about death and falling buildings, but also the rebuilding of the city. Earlier this month, the San Francisco Ballet held a one-off solo dance performance to the beat of seismic data broadcast live from the Hayward fault. The information triggered sounds such as thunder claps and crashing waves while principal dancer Muriel Maffre improvised. It was “well conceived and beautiful”, the San Francisco Chronicle reported, although not quite as “leading edge” as claimed. At one stage there was a “haunted-house cacophony of screams and clinking chains and running water”, the paper’s critic said. There is a small, dwindling group of survivors from the quake, many of whom were just babies when it struck. A group of five of them - the oldest is 108 - recently met in San Francisco and happily gave interviews to journalists. They will attend a special commemoration breakfast today. One survivor, Della Bacchini, 101, who was one year old in 1906, told the San Francisco Examiner that it was important for the city’s residents to keep the history of the quake alive. "San Franciscans have a lot of guts," she said. “We’ve gone through earthquakes and fires, and the people have stuck together. Certainly, the city’s regeneration after 1906 was remarkable, with three-quarters of the lost buildings replaced within three years. A reinvented San Francisco was unveiled in 1915 with its Panama-Pacific International Exposition. In a commemorative lecture, Kenneth Starr, professor of history at the University of California, compared the compulsion to rebuild in 1906 with the plans to rebuild New Orleans after last year’s disaster: “Once they’re dreamed, once they’ve been there … they never disappear.

Read the following passage and choose the best answer (A, B, C, D):
An individual’s personality is the complex of mental characteristics that makes them unique from other people. It includes all of the patterns of thought and emotions that cause us to do and say things in particular ways. At a basic level, personality is expressed through our temperament or emotional tone. However, personality also colors our values, beliefs, and expectations. There are many potential factors that are involved in shaping a personality. These factors are usually seen as coming from heredity and the environment. Research by psychologists over the last several decades has increasingly pointed to hereditary factors being more important, especially for basic personality traits such as emotional tone. However, the acquisition of values, beliefs, and expectations seem to be due more to socialization and unique experiences, especially during childhood. Some hereditary factors that contribute to personality development do so as a result of interactions with the particular social environment in which people live. For instance, your genetically inherited physical and mental capabilities have an impact on how others see you and, subsequently, how you see yourself. Likewise, your health and physical appearance are likely to be very important in your personality development. You may be frail or robust. You may have a learning disability. You may be slender in a culture that considers obesity attractive or vice versa. These largely hereditary factors are likely to cause you to feel that you are nice-looking, ugly, or just adequate. Likewise, skin color, gender, and sexual orientation are likely to have a major impact on how you perceive yourself. Whether you are accepted by others as being normal or abnormal can lead you to think and act in a socially acceptable or marginal and even deviant way. There are many potential environmental influences that help to shape personality. Child rearing practices are especially critical. In the dominant culture of North America, children are usually raised in ways that encourage them to become self-reliant and independent. Children are often allowed to act somewhat like equals to their parents. Children are given allowances and small jobs around the house to teach them how to be responsible for themselves. In contrast, children in China are usually encouraged to think and act as a member of their family and to suppress their own wishes when they are in conflict with the needs of the family. Independence and self-reliance are viewed as an indication of family failure and are discouraged.

Read the following passage and choose the best answer (A, B, C, D):
Global sea level has been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average-the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year. Higher sea levels mean that deadly and destructive storm surges push farther inland than they once did, which also means more frequent nuisance flooding. Disruptive and expensive, nuisance flooding is estimated to be from 300 percent to 900 percent more frequent within U.S. coastal communities than it was just 50 years ago. The two major causes of global sea level rise are thermal expansion caused by warming of the ocean since water expands as it warms, and increased melting of land-based ice, such as glaciers and ice sheets. The oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity. With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century. In the United States, almost 40 percent of the population lives in relatively high-population-density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. Globally, eight of the world’s 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans. Sea level rise at specific locations may be more or less than the global average due to local factors such as land subsidence from natural processes and withdrawal of groundwater and fossil fuels, changes in regional ocean currents, and whether the land is still rebounding from the compressive weight of Ice Age glaciers. In urban settings, rising seas threaten infrastructure necessary for local jobs and regional industries. Roads, bridges, subways, water supplies, oil and gas wells, power plants, sewage treatment plants, landfills-virtually all human infrastructure-is at risk from sea level rise.

Read the following passage and choose the best answer (A, B, C, D):
The past fifty years or so have seen the gradual disappearing of animals from this earth, fishes from the sea, trees and plants from the land. Many factors result in this unpleasant phenomenon. Among them, hunting is the main factor that endangers wildlife. Some people kill wildlife for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales. Apart from this, the rapidly growing human population threatens wildlife on land, too. Towns expand and roads have to be built, so forests are burnt and trees are chopped down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wildlife. Tigers, lions and leopards slowly die off without the food and shelter that the forests provide. In addition, rapid urbanization means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened. Man depends greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot do without wildlife; or he himself would become extinct. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wildlife to continue living rather than to remove all signs of it. Man must learn to farm the sea as he does the land. He should regulate the amount and the frequency of his catch. He should allow fish to breed and multiply before netting them. Man also needs to build forest reserves, and to pass laws prohibiting the killing of animals, especially those that are already rare. To retain the present animal kingdom, the least that man can do is to clean the seas and rivers and to prevent pollution. The cycle of nature is such that it forms a vicious circle. The insecticides and pesticides that we spray on crops can kill the birds and animals that feed on them. When man eats these poisoned animals, he himself can die. We must therefore test the chemicals to be used before they are sprayed or it might mean the death of man!

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

Read the following passage and choose the best answer (A, B, C, D):
Thunderstorms, with their jagged bursts of lightning and roaring thunder, are actually one of nature’s primary mechanisms for transferring heat from the surface of the earth into the atmosphere. A thunderstorm starts when low-lying pockets of warm air from the surface of the earth begin to rise. The pockets of warm air float upward through the air above that is both cooler and heavier. The rising pockets cool as their pressure decreases, and their latent heat is released above the condensation line through the formation of cumulus clouds. What will happen with these clouds depends on the temperature of the atmosphere. In winter, the air temperature differential between higher and lower altitudes is not extremely great, and the temperature of the rising air mass drops more slowly. During these colder months, the atmosphere, therefore, tends to remain rather stable. In summer, however, when there is a high accumulation of heat near the earth’s surface, in direct contrast to the considerably colder air higher up, the temperature differential between higher and lower altitudes is much more pronounced. As warm air rises in this type of environment, the temperature drops much more rapidly than it does in winter; when the temperature drops more than 4 degrees Fahrenheit per thousand feet of altitude, cumulus clouds aggregate into a single massive cumulonimbus cloud, or thunderhead. In isolation, a single thunderstorm is an impressive but fairly benign way for Mother Earth to defuse trapped heat from her surface; thunderstorms, however, can appear in concert, and the resulting show, while extremely impressive, can also prove extraordinarily destructive. When there is a large-scale collision between cold air and warm air masses during the summer months, a squall line, or series of thunderheads, may develop. It is common for a squall line to begin when an advancing cold front meets up with and forces itself under a layer of warm and moist air, creating a line of thunderstorms that races forward at speeds of approximately forty miles per hour. A squall line, which can be hundreds of miles long and can contain fifty distinct thunderheads, is a magnificent force of nature with incredible potential for destruction. Within the squall line, often near its southern end, can be found supercells, long-lived rotating storms of exceptional strength that serve as the source of tornadoes.

Swine influenza (also called swine flu, hog flu and pig flu) is an infection of a host animal by any one of several specific types of microscopic organisms called "swine influenza virus". A swine influenza virus (SIV) is any strain of the influenza family of viruses that is usually hosted by (is endemic in) pigs. As of 2009, the known SIV strains are the influenza c virus and the subtypes of the influenza A virus known as HI N1, H1N2, H3N1, H3N2 and H2N3. Swine influenza is common in pigs in the mid-western United States (and occasionally in other states), Mexico, Canada, South America, Europe (including the UK, Sweden and Italy) Kenya Mainland China, Taiwan Japan and other parts of eastern Asia.

Transmission of swine influenza vims from pigs to humans is not common and does not always cause human influenza, often only resulting in the production of antibodies in the blood. The meat of the animal poses no risk of transmitting the virus when properly cooked. If transmission does cause human influenza, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at increased risk of catching swine flu. In the mid-20th century, identification of influenza subtypes became possible. This allows accurate diagnosis of transmission to humans. Since then, fifty confirmed transmissions have been recorded. Rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general namely chills fever sore throat, muscle pains severe headache, coughing, weakness and general discomfort.

The 2009 flu outbreak in humans known as "swine flu" is due to a new strain of influenza A virus subtype H1N1 that contains genes closely related to swine influenza. The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs. This strain can be transmitted from human to human, and causes the normal symptoms of influenza

There is still no consensus about how the Neanderthals were driven to extinction,  leaving our Homo sapien ancestors without any competition. The disappearance of the native European Neanderthals is odd partly because their shorter, stockier bodies must have made them better able to withstand the colder temperatures that prevailed when their cousins from Africa entered Europe. With a smaller surface area the Neanderthal body would have been able to retain more heat. The once common assumption that the key was the inferior vocal abilities of the Neanderthal has since been disproved by research on the Neanderthal hyoid bone, located in the throat. The larger skull capacity and brain is another respect in which they do not seem to have been inferior.  It was once thought that proof of a superior intellect was to be found in the narrower Homo sapien stone tools known as “blades”, which were assumed to be more efficient than the broader “flakes” used by the Neanderthals. In a number of important respects, including durability, this idea has proved to be unfounded. However, the blades would have been more effective as tips for throwing spears whereas the stone flakes would have been limited to the kind of thrusting spears the Neanderthals are believed to have used. This could have combined with the greater agility of the Homo sapiens to give them a distinct advantage in hunting on open terrain. Crucial in this respect were the larger canals in the Homo sapien inner ear, providing a more acute sense of balance, in addition to the longer limbs and lighter build. The Neanderthal technique of hiding and lying in wait for passing animals ceased to be viable when the dense forests of Europe began to recede. After a period of co-existence with their cousins, the Neanderthals were slowly eradicated.

The dramatic growth of the world's population in the twentieth century was on a scale without parallel in human history. Most of this growth had occurred since 1950 and was known as the population 'explosion'. Between 1950 and 1980 the world population increased from 2.5 to over 4 billion, and by the end of the twenty century the figure had risen to about 6.6 billion. Growth of this size cannot continue indefinitely. Recent forecasts suggest that the total population will level out at between 10 and 15 billion in the mid twenty first century. Already there are encouraging signs that the rate of increase in many less developed countries is beginning to slow down.

It has been forecast that, by the middle of the twenty-first century _____.

“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.”
