The rules of etiquette in American restaurants depend upon a number of factors the physical location of the restaurant, eg., rural or urban; the type of restaurant, eg., informal or formal; and certain standards that are more universal. In other words, some standards of etiquette vary significantly while other standards apply almost anywhere. Learning the proper etiquette in a particular type of restaurant in a particular area may sometimes require instruction, but more commonly it simply requires sensitivity and experience. For example, while it is acceptable to read a magazine in a coffee shop, it is inappropriate to do the same in a more luxurious setting. And, if you are eating in a very rustic setting it may be fine to tuck your napkin into your shirt, but if you are in a sophisticated urban restaurant this behavior would demonstrate a lack of manners. It is safe to say, however, that in virtually every restaurant it is unacceptable to indiscriminately throw your food on the floor. The conclusion we can most likely draw from the above is that while the types and locations of restaurant determine etiquette appropriate to them, some rules apply to all restaurant.

Telecommunicating is a form of computer communication between employees’ homes and offices. For employees whose jobs involve sitting at a terminal or word processor entering data or typing reports, the location of the computer is of no consequence. If the machine can communicate over

telephone lines, when the work is completed, employees can dial the office computer from a distant site and transmit the material to their employers. A recent survey in USA Today estimates that there are approximately 8.7 million telecommuters. But although the numbers are rising annually, the trend does not appear to be as significant as predicted when Business Week published "The Portable Executive" as its cover story a few years ago. Why hasn't telecommuting become more popular?
Clearly, change simply takes time. But in addition, there has been active resistance on the part of many managers. These executives claim that supervising the telecommuters in a large work force scattered across the country would be too difficult, or, at least, systems for managing them are not yet developed, thereby complicating the manager's responsibilities.
It is also true that employees who are given the option of telecommuting are often reluctant to accept the opportunity. Most people feel that they need regular interaction with a group, and many are concerned that they will not have the same consideration for advancement if they are not more visible in the office setting. Some people feel that even when a space in their homes is set aside as a work area, they never really get away from the office.

The phrase “of no consequence” means     .

Aspirin's origins go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flvor in the bark of the willow tree. To Stone, this particular bark seem to have much in common with "Peruvian Bark", which had been used medicinally since the 1640s to bring down fevers and to treat malaria, stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, stone presented his tiding to the British Royal Society. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today's aspirin. The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid.The trade name "aspirin" was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The fist bottles of aspirin actually went on sale to the publicjust prior to the turn of the century, in 1899.

The Advancing Development of Artificial Limbs
It wasn’t very long ago that losing a limb automatically meant a drastic drop in the quality of a person’s life. Thanks to the wonders of modern science, people now are recovering from all sorts of horrendous injuries that let them disabled. The reason they are able to do so is remarkable advances made in the field of artificial limbs. Doctors have been creating prosthetic limbs for their patients dating back to ancient Greece. For most of history, however, these replacements were mainly for cosmetic purposes. Pirates, knights, loot soldiers that lost their limbs in battle would get them, so they wouldn’t lose face when returning to society. It wasn’t until the mid-19th century that doctors were able to perform surgeries to reliably attach limbs to people’s bodies and amputate limbs without causing serious infection. Modern artificial limbs represent a tremendous leap forward in terms of form and function. Today’s limbs are far more durable and can withstand a lot more wear and tear. An amazing example of how far artificial limbs have progressed is the Flex-Foot Cheetah. Made from carbon fiber, it is able to store energy as the person moves, which enables the wearer to run and jump. The technology is so good that approximately 90 percent of all Special Olympic amputees use them in competition. Meanwhile, the Bebionic3 has emerged as the most advanced prosthetic arm available. It has been nicknamed “The Terminator” because it is similar to Arnold Schwarzenegger’s mechanical limbs in the famous blockbuster film. The Bebionic3 can perform a multitude of tasks including writing, tying a shoelace, lifting heavy objects, and even pouring a beer. Wearers simply push a button on the base of the arm and the Bebionic3 will work its magic. In September 2013, scientists took another giant leap forward when they successfully fitted a patient with an artificial leg that can be controlled by thought. Two of the patient’s nerves were attached to his hamstring muscle. These nerves then interact with sensors inside the artificial leg. Sensors will then transmit these messages to a computer which will follow through on his instructions. Therefore, if the patient wants to stretch out his leg, the computer will understand this command and send a message to the limb and instruct it to do so. If artificial limb technology keeps advancing like this, losing a limb may not be such a big deal.
1. What would happen when someone in the past needed to get an artificial limb?

The Greatest Light Show on the Earth
If you are a fan of amazing visual displays, planetariums around the world offer some entertaining laser-light shows that are often accompanied by popular music. Yet if you want to see the world’s greatest light show, you won’t be able to catch it indoors. Instead, you will have to head to one of the Poles. In certain spots, you will be treated to colourful streaks of light dancing across the sky. This incredible display is the aurora borealis, and every year people from all corners of the globe flock to witness its wonders firsthand. The Aurora Borealis, or Northern Lights, got its official name in 1621. The name combines the name of the Roman goddess of the dawn, Aurora, and the Roman god of the north wind, Boreas. In ancient times, the aurora completely baffled people’s minds, as science was far more primitive than it is today. Nevertheless, they created many myths to explain them. The Vikings believed the lights were the reflection of dead maidens. The Scots thought they were supernatural beings battling in heaven. Meanwhile, Eskimos thought that the lights were dead souls, and when the colours changed, it was their attempt to contact living friends and relatives. It was not until 2008 that a team of scientists from ULCA finally concluded with certainty what the true cause of these dancing light is. The process begins when solar winds carry charged particles from the Sun through space and into the Earth’s atmosphere. When these charged particles enter the Earth’s atmosphere, they are magnetically attracted to the Earth’s poles. During their journey to these points, they come in contact with nitrogen and oxygen atoms in the sky. These collisions are what cause the aurora. The heights at which the collisions occur determine the colours of the individual lights. For example, when the solar winds collide with nitrogen at least than 96 kilometres above the Earth’s surface, the lights will be blue. If the same collision occurs above 96 kilometres, however, the light will be purple. Or, if the solar wind particles collide with oxygen, the colours produced will be either red or green. However, merely understanding how the aurora works does not do this phenomena justice. To truly appreciate the full splendor of the aurora, you will have to see this Natural Wonder of the World in person.

Hunting Down the Truth about Killer Whales
Hearing that killer whales are in the area is sure to strike fear in the heart of anyone at sea. The thought of coming across a creature with a menacing name like that is a surefire sign you are on a path to destruction. As it turns out, killer whales, orcas, are actually highly sophisticated creatures that are usually harmless to humans. The title “killer whale” may actually be a mistranslation of the Spanish term “ballena asesina”, which means assassin whale. Orcas were nicknamed this due to their well-coordinated attacks on marine life, not for the danger they pose to humans. At nearly five to seven metres in length and a weight of over six tons, orcas are one of the largest creatures on the Earth. There are about 50,000 orcas worldwide that are spread out in several oceans. Orcas are classified as an Apex predator, which means no other creature hunt them for food. Scientists believe that there are between three to five different types of orca and they are all quite distinctive. The most frequently seen of these are Residents. They live in close-knit family units called pods, which can contain over 50 members, and their diet consists mainly of fish. Transient whales, however, prefer to travel in smaller groups of two to six whales. Meanwhile, Offshore whales were only recently discovered in 1988. They prefer to swim farther away from land than the others and several pods may come together to form groups as large as 200 whales. Although these orca groups may seem similar to the naked eye, they are extremely different in many ways, and scientists believe they haven’t interbred in thousands of years. Researchers also acknowledge that their knowledge of orcas is limited, and even more groups may exist. Male orcas have an average lifespan of about 30 years, while the average age for females is 50. However, there have been cases of females living up to 90 years. Yet when kept in captivity at marine entertainment parks, their life expectancies drop dramatically. In fact, it seems that the biggest threat to orcas these days is humans. Between the practices of hunting orcas, polluting their environments, and capturing them for entertainment purposes, we are making it very difficult for them to survive. Perhaps the killer whales aren’t the real killer after all.
7. What does the sentence “Although these orca groups may seem similar to the naked eye, they are extremely different in many ways” 1 in paragraph 3 mean?

Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centres, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the
clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water. The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity. Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has 30 per cent of its population, and has experienced declining winter rainfall since the 1980s.
In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water.

Which of the following is NOT mentioned as a process of conversing seawater to freshwater?
