Most households in the UK will have a broadband connection and a lot of those  houses will also have experienced connection or speed issues. But what if there was a way to connect to the internet and benefit from a direct connection with much faster speeds? Enter Li-Fi.  Li-Fi stands for Light Fidelity and is a Visible Light Communications (VLC) system which runs wireless communications that travel at very high speeds. With Li-Fi, your light blub is essentially your router. It uses common household LED light bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.  Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves, while Li-Fi runs on visible light waves. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into “streamable” content. For example, data is fed into an LED light bulb, it then sends data at rapid speeds to the photo-detector. The tiny changes in the rapid dimming of LED bulbs is then converted by the “receiver” into electrical signal. The signal is then converted back into a binary data stream that we would recognise as web, video and audio applications that run on internet-enabled devices.  While some may think that Li-Fi with its 224 gigabits per second leaves Wi-Fi in the dust, Li-Fi’s exclusive use of visible light could halt a mass uptake. Li-Fi signals cannot pass through walls, so in order to enjoy full connectivity, capable LED bulbs will need to be placed throughout the home. Not to mention, Li-Fi requires the light bulb is on at all times to provide connectivity, meaning that the lights will need to be on during the day. Additionally, where there is a lack of light bulbs, there is a lack of Li-Fi internet so Li-Fi does take a hit when it comes to public Wi-Fi networks.  However, using Li-Fi instead of Wi-Fi, you’ll negate lots of security problems associated with shared and often overloaded broadband networks. It will also be advantageous in areas where radio frequency waves do not reach. Due to its impressive speeds, Li-Fi could make a huge impact on the internet of things too, with data transferred at much higher levels with even more devices able to connect to one another. 
3. According to paragraph 3, what form does the transferred data from Li-Fi system take?

If parents bring up a child with the sole aim of turning the child into a genius, they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes which ambitious parents make. Generally, the child will be only too aware of what his parents expect, and will fail. Unrealistic parental expectations can cause great damage to children.
However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child. Michael Collins is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers twice a week for violin lessons. Michael's mother knows very little about music, but his father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling.
Winston Smith, Michael's friend, however, is not so lucky. Both his parents are successful musicians, and they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.

Who have criticized the methods of some ambitious parents?

Scientist and inventor George Washington Carver was born into slavery during the American Civil War. After the war, he worked diligently to get an education. He managed to get an advanced degree in Botany, which is the study of plants. After he finished his college degree, he worked in the South. He taught people about botany and about how it could be used to improve farming. Carver learned that there was a problem with cotton farming in the South. Cotton takes nutrients from the soil. If cotton is planted year after year, the quality of the soil decreases. Carver knew that plants like peanuts and sweet potatoes are different from cotton. They add nutrients to the soil rather than take nutrients from the soil. Carver told farmers that it was a bad idea to grow only cotton and no other crops each year. He told them that they should also grow plants like peanuts and sweet potatoes, which improve the quality of the  soil. Many farmers followed the advice that Carver offered them. The result was that the production on their farms increased. This increased production of peanuts and sweet potatoes improved the quality of the soil. However, when production of peanuts and sweet potatoes increased, a new problem developed. The new problem was that there were too much peanuts and sweet potatoes. To solve this problem, Carver began working in a laboratory to find new uses for peanuts and sweet potatoes. He developed hundreds of products that could be made from peanuts and sweet potatoes. These hundreds of products included food products, medicines, plastics and fertilizer

Herman Melville, an American author best known today for his novel Moby Dick, was actually more popular during his lifetime for some of his other works. He traveled extensively and used the knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849). In 1841, Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered around the islands of Tahiti and Moorea.This South Sea island sojourn was a backdrop to the novel Omoo (1847). After three years awayfrom home, Melville joined up with a U.S. naval frigate that was returning to the eastern United States around Cape Horn. The novel White Jacket (1850) describes this lengthy voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of humanity against the universe. The public was not ready for Melville's literary metamorphosis from romantic adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's popularity during his lifetime is the one for which he is best known today.

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!

Read the following passage and choose the best answer (A, B, C, D):
Spend just a minute watching the world population counter tick up on Worldometers and you’ll see just how quickly we’re swelling in numbers. The current figure stands at around 7.7 billion, and this is projected to become 9.8 billion by 2050, according to the UN. More people means more carbon footprints - more cars, waste and emissions, more houses and infrastructure to be constructed using the world’s limited resources, more mouths to be fed using more water and energy in food production. Governments recognise the severity of the situation and have mostly come together over global policies like the UN’s Paris Agreement, to limit carbon emissions and their impact on climate change. In addition, new technologies are being developed to make our use of resources more efficient. As for controlling population growth, the education of women is one key factor. Research shows the higher level to which a woman is educated, the fewer children she is likely to have. In Ghana, for example, women who have been to high school, have a fertility rate of between two and three children, compared with six for those who have no education. This could be for several reasons including learning about desired family size and understanding child health better. This means that the mother is more confident her children will survive. She is also likely to hold more sway within the family, arguing for fewer children if that is what she wants.  There is also plenty that individuals can do to reduce their personal footprint. Earth Overshoot Day is defined as the day when humanity has used up nature’s resource budget for the year. The Global Footprint Network calculates that moving Earth Overshoot day back by five days every year would mean that, by 2050, we’d be using the resources of less than one planet. Just eating 50% less meat and replacing it with vegetarian alternatives could save the planet five days. As David Attenborough says, if we want to save Earth, we can no longer afford to keep eating meat: “We are omnivores, so biologically, if you could have a biological morality, you can say, yes we evolved to eat pretty well everything. But now we’ve got to a stage in our own social evolution in which that is no longer practical.” Sir David says he himself now eats less meat and is bolstered by the knowledge that it’s helping the planet.

Read the following passage and choose the best answer (A, B, C, D):
200 years ago there were less than one billion humans living on earth. Today, according to UN calculations there are over 7 billion of us. Recent estimates suggest that today’s population size is roughly equivalent to 6.9% of the total number of people ever born. This is the most conspicuous fact about world population growth: for thousands of years, the population grew only slowly but in recent centuries, it has jumped dramatically. Between 1900 and 2000, the increase in world population was three times greater than during the entire previous history of humanity—an increase from 1.5 to 6.1 billion in just 100 years. How the world population is changing is of great importance for humanity’s impact on the Earth’s natural environment, but it also gives reasons to hope for a good future. This is because we have a bigger team of better educated people who can contribute to the solutions that improve global well-being. A picture of the world population in the very long-run shows extremely rapid growth. Indeed, for a long time the world population grew at an increasing rate. However, if we focus on the last couple of decades, we see that this pattern no longer holds, as the annual rate of population growth has been recently going down. 1962 saw the growth rate peak at 2.1%, and it has since fallen to almost half. A long historical period of accelerated growth has thus come to an end. Based on these observations, world history can be divided into three periods marked by distinct trends in population growth. The first period, pre-modernity, was a very long age of very slow population growth. The second period, beginning with the onset of modernity— which was characterized by rising standards of living and improving health—had an increasing growth rate that continued to rise through 1962. Today, the second period is over, and the third period is unfolding; the population growth rate is falling and will likely continue to fall, leading to an end of population growth towards the end of this century.

Certainly no creature in the sea is odder than the common sea cucumber. All living creature, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets? For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to such up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-color and nearly white. One form even has vivid purple tentacle. Usually the creatures are cucumber-shaped-hence their name-and because they are typically rock inhabitants, this shape, combine with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents. Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become quiescent and live at a low metabolic rate-feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in a short time and would probably starve themselves out of existence. But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs, when attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attached or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.

Read the following passage and choose the best answer (A, B, C, D):
Zoos used to be primarily a place for people to see wild animals they had never seen.  Now, however, zoos serve a new purpose – to be captive-breeding programs for endangered animals. There are less than a hundred Sumatran rhinos worldwide, and three were born in Cincinnati Zoo. When old enough, one of the males was sent to Way Kamabas National Park in Sumatra and this helped to start the process of re-populating his species in the wild and saving it from the extinction.  Other zoos have started captive-breeding programs as well. Zoos have saved the Arabian onyx, the black-footed ferret, the red wolf, the Guam rail, and the California condor. But the cost of the programs for saving the threatened animals is not cheap. The condor program alone costs up to $2 million a year. While it is mostly large-city zoos involved in captive breeding, smaller zoos do their part. The Miller Park Zoo in Bloomington, Illinois, is working on breeding the endangered, and small. Mount Graham red squirrel.  Zoos have always been involved in animal conservation to some degree, but the question of which animals to save is a big one. Endangered animals may not be the most exciting to see in a zoo, and to di conservation work the zoos must survive financially. Space is a problem as well. A zoo might be able to save a small number of large animals or a large number of small ones. Currently, the most threatened group of animals is amphibians. Zoos realize that visitors may not want to see frogs, salamanders, or other small animals and may only pay to see rhinos, lions, and tigers. Some scientists believe zoos should be less tourist attractions and more conservation sanctuaries. Thus, although zoos continue to do good work, they still confront tricky questions. There are a limited number of animals that can be cared for in zoos, and that means many species on the edge of extinction may not survive. The Sumatran orangutan and a thousand other threatened species have not made it into a captive-breeding program, but the species will continue to exist. How? In the Frozen Zoo. Cells from these animals are stored in the San Diego Zoo Institute for Conservation Research in liquid nitrogen. Only one animal in the Frozen Zoo is presently extinct, but many others are at dire risk. In the Frozen Zoo, however, the cells of animals will be preserved for study through their genetic material.

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.

Stabilisation work means the Leaning Tower of Pisa is leaning slightly less than it used to, experts have said. The tower, which has leaned to one side ever since it began to take shape in 1173, has lost 4cm of its tilt over the past two decades, according to a report from the surveillance group that meets every three months to give updates on the monument’s condition “Since restorative work began, the tower is leaning about half a degree less,” said Nunziante Squeglia, a geotechnics professor at the University of Pisa who works with the group. “But what counts is the stability of the tower, which is better than initially predicted.” The structure, which was badly damaged during the second world war, was closed to the public in 1990 over safety fears and did not reopen for 11 years. The surveillance group was set up in 2001 ago after Michele Jamiolkowski, an engineer of Polish origin, coordinated an international committee to save the landmark. The bell tower, a symbol of the power of the maritime republic of Pisa in the Middle Ages, was defective from the beginning due to the porous clay soil beneath its foundations. After three floors were completed, construction stopped and did not resume until 90 years later when workers started building additional floors on a diagonal to offset the lean. But work was again disrupted before finally being completed in 1372. The tower, located behind Pisa’s cathedral, attracts more than 5 million visitors a year. Reaching the top requires climbing 269 steps. The surveillance group’s work, which is funded by the non-profit Opera della Primaziale Pisana, includes improving the quality of the structure’s conservation and promoting research.
