Frozen Fitness
A man stands over a bathtub that is filled with ice. Although it is the middle of winter, he slowly slides into the tub and submerges his body underneath the water. Within seconds, he begins to shiver, but after a few minutes he is able to settle down. Despite the temperature, he will remain in the tub for the next 30 minutes. He is taking advantage of cold thermogenesis, a growing trend that could improve people’s health. Thermogenesis is an internal process that mammals undergo to generate heat when they are subjected to cold temperatures. In modern society, humans rarely requires this ability because we have heated homes and offices during the winter season. Recent studies, however, indicate that by doing so we could be missing out on some wonderful health benefits. Being subjected to cold temperatures regularly has been shown to boost men’s testosterone levels. It also boosts metabolism, which allows people to burn fat more efficiently. Some people have reported that cold thermogenesis also provides a mental lift once you have overcome the initial shock of the cold water. The positive effects of thermogenesis were known before, but it only started to become popular after the 2008 Olympics. One man who helped spark this craze was Ray Cronise, a NASA scientist and entrepreneur. He was reading an article that reported Michael Phelps ate 12,000 calories per day while training. The calories were so high that led him to believe that something else besides exercise was helping Phelps to stay thin and muscular: the icy water in the swimming pool. So he conducted his own experiment by drinking several glasses of ice water and exposing himself to cold water. After six weeks of this regiment, he had lost 30 pounds. There are several routines that a person can adopt if they are interested in starting their own thermogenesis routine. One method is ice baths. This method may be a bit too drastic for average people though. Instead, people may want to begin by dunking their face in cold water for a few seconds, and then gradually increase the time. Next, they can progress to cold showers and baths before moving on ice baths. An even more convenient way is to place an ice packet on the back of your neck for 15 to 20 minutes every evening. Although these methods may be extreme, many are willing to give them a go to improve their health

However, the thing I love most is that the house also has a big garden and a large pond behind it. These are the places where my family likes to relax or fish on weekends.

How many people are there in Anna's family?

The ability to conduct electricity is one of the key properties of a metal. Other solid material such as silicon can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The lost electrons are free to move in what are known as a sea of electrons. Since the electrons are negatively charged they attract the ions and this is what keeps the structure together.

An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they can be made to flow in one direction when a source of electrical energy such as a battery is connected to the metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good conductors of electricity. The only other common solid conducting material that pencil users are likely to encounter is graphite (what the 'lead' of a pencil is made from). Graphite is a form of carbon and again the carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow.

Electrical insulators are substances that cannot conduct electricity well either, because they contain no charged particles or any charged particles they might contain do not flow easily. Water itself is a poor conductor or electricity as it does not contain a significant amount of fully charged particles (the ends of a water molecule are partly charged but overall the molecule is neutral). However, most water we encounter does contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin through perspiration and it dissolves in the water to make it more conductive.

Salt in its solid state is not able to conduct electricity because________.

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.

Read the following passage and choose the best answer (A, B, C, D):
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 Particle that Started the Big Bang
In 2013, the Nobel Prize for Physics was awarded to Francois Englert and Peter W. Higgs for their discovery of a particle that is vital to our understanding of the universe. Although its official name is the Higgs boson, many refer to it as the God particle, because it’s considered to be the building block of the universe. Many believe that the Higgs boson may be the cause for the Big Bang explosion which led to the creation of the universe. In the 1960s, Higgs came up with the concept that particles had no mass when the universe started. In a split-second, however, it came into contact with something that gave it mass. This, Higgs theorized, was the Higgs boson. Many scientists initially laughed at the idea, but in the upcoming years, Higgs along with Englert and several of their peers continued to work on these concepts. Their ideas would eventually help lead the way to the discovery of the Higgs boson decades later. The search for the Higgs boson certainly didn’t come up cheap, as it cost nearly $10 billion to build the machinery necessary to perform the tests to find it. Yet nearly every physicist would agree that it was worth it, as the Higgs boson has already been labeled as one of the most important discoveries in particle physics. The finding is also a huge boost for physics in general because it proves that the Standard Model of Physics which researchers have been using for years is correct. The Higgs was the last remaining question mark as all of the other particles and elements had been found. Still, many ordinary people may question how such a discovery affects their lives at all. Although quantum mechanics may seem weird, it has actually led to several important technological breakthroughs over the past century. These findings have led to laser and X-ray technologies that work in the real world. There is still much to be learned with further observation of the Higgs boson in action. Scientists hope to learn more about dark matter, a strange substance that constitutes 25 percent of the mass of the universe. The research could also lead to some other technologies as well.
