No More Polar Bears?
We all know that the Earth is getting warmer and warmer. This problem is called “global warming”. We also know that global warming is causing a lot of problems. Ocean levels are getting higher and higher. Because ocean levels are getting higher, storms are getting stronger and stronger. This list of problems goes on and on. Animals are suffering a lot because of global warming. Polar bears are suffering more than most animals. This is because polar bears live in the North Pole. In the North Pole, global warming is making ice melt. Polar bears hunt from large pieces of floating ice. They jump off the ice and hunt for food. Polar bears have to swim and find these floating pieces of ice. These days, they have to swim farther to find the floating ice. Many of them don’t have enough energy. They get too tired, and they die in the water. Polar bears are suffering because of other problems, too. Pollution makes their water dirty. Many countries go to the North Pole to look for oil and gas, and they damage the environment of the bears. In addition, when ships sail through the North Pole, they cause a lot of damage. Finally, people hunt and kill too many polar bears. However, melting ice is definitely the biggest problem. Right now, there are about 25,000 polar bears in the world. If global warming continues, there may be only about 12,000 in the year 2050. By the year 2080, that number might be much smaller. It is important to study polar bears. When we learn about polar bears, we also learn about the health of the North Pole. If polar bears are doing well, then the environment in the North Pole is probably healthy. If polar bears are suffering then there are probably serious problems in the North Pole. Right now, governments around the world are working to help polar bears. There are new laws that protect polar bears. However, if global warming continues to get worse, polar bears may disappear forever.

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.

Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.
6. In order for life to develop, a planet’s orbit must not be

Don’t Handle with Care
People always go shopping for the latest and greatest gadgets. Speed, performance, and the latest functions are always key factors before making a purchase. Yet the most important factor of all, which often isn’t considered, is a product’s durability. After all, if a product breaks easily and can’t be repaired, the buyer will have wasted their investment. In other cases, weakly-designed product can cost someone their life. Thankfully, today’s inventors and engineers coming up with some incredible ways to ensure that many products can survive the most difficult situations. One area where durability is absolutely essential is in designing weaponry. In the industry, lapses in quality can lead to death. Designers of military vehicles have recently made great strides in creating some extra tough bulletproof vehicles. Researchers were inspired by the advances made with a similar technology, bulletproof vests. This equipment, which keeps police officers and soldiers protected from gunfire, has been continually upgraded as time has gone on. In order to get tougher, these vests have got lighter, so officers and soldiers can move more freely while working. Beautiful screens, a fast computer processor, and the latest software are probably the biggest concerns for most people shopping for new smartphones. Yet, since most mobiles will be subject to their fair share of bumps and bruises during their life cycle, durability should also be a major concern. A major breakthrough in recent years was the invention of Gorilla Glass. This technology not only prevents devices from breaking when dropped on hard surfaces, but it also makes them scratch-resistant as well. Gorilla Glass screens are given molten alkaline salt baths that produce a hard, compressed layer at the surface. Before a screen can crack, it will have to penetrate this rugged surface, which takes a large degree of force. Recently, another new technique called electrospinning was developed that could make future products even tougher to break. The process involves applying high voltage to a polymer to create a strand of nanofiber. Products designed with the material will be able to absorb more energy without breaking. Researchers are aiming to lighten up aircraft and potentially decrease the damage planes suffer in crashes. Hopefully, these advances are just the beginning. Although science has come a long way in helping manufacturers to create more durable products, the next century should surely bring some even more incredible improvements.

Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology. Deep inside the brain there is a "clock" that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the circadian clock (from the Latin, circa "about" + dies "day").

This body clock programmes us to be sleepy twice a day, between 3-5 a.m and again between 3-5 p.m. Afternoon tea and siesta times are all cultural responses to our natural biological sleepiness in the afternoon. One of the major causes of the travelers' malady known as jet lag is the non-alignment of a person's internal body clock with clocks in the external world. Crossing different time zones confuses the circadian clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjust to a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may be on a different schedule altogether.

Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to shrink our day. That is why travelling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quantity and quality than eastward flights. When flying west, you are "extending" your day, thus travelling in the natural direction of your internal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency.

One of the more common complaints of travelers is that their sleep becomes disrupted. There are many reasons for this: Changing time zones and schedules, changing light and activity levels, trying to sleep when your body clock is programmed to be awake, disruption of the internal circadian clock and working longer hours. Sleep loss, jet lag and fatigue can seriously affect our ability to function well. Judgment and decision-making can be reduced by 50%, attention by 75 percent, memory by 20 percent and communication by 30 percent. It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination's schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone

Prehistoric mammoths have been preserved in the famous tar pits of Rancho La Brea (Brea is the Spanish word for tar) in what is now the heart of Los Angeles, California. These tar pits have been known for centuries and were formerly mine for their natural asphalt, a black or brown petroleum-like substance. Thousands of tons were extracted before 1875, when it was first noticed that the tar contained fossil remains. Major excavations were undertaken that established the significance of this remarkable site. The tar pits were found to contain the remains of scores of species of animals from the last 30,000 years of the Ice Age. Since then, over 100 tons of fossils, 1.5 million from vertebrates, 2.5 million from invertebrates, have been recovered, often in densely concentrated tangled masses. The creatures found range from insects and birds to giant ground sloths, but a total of 17 proboscideans (animals with a proboscis or long nose) - including mastodons and Columbian mammoths - have been recovered, most of them from Pit 9, the deepest bone-bearing deposit, which was excavated in 1914. Most of the fossils date to between 40,000 and 10,000 years ago. The asphalt at La Brea seeps to the surface, especially in the summer, and forms shallow puddles that would often have been concealed by leaves and dust. Unwary animals would become trapped on these thin sheets of liquid asphalt, which are extremely sticky in warm weather. Stuck, the unfortunate beasts would die of exhaustion and hunger or fall prey to predators that often also became stuck. As the animals decayed, more scavengers would be attracted and caught in their turn. Carnivores greatly outnumber herbivores in the collection: for every large herbivore, there is one saber-tooth cat, a coyote, and four wolves. The fact that some bones are heavily weathered shows that some bodies remained above the surface for weeks or months. Bacteria in the asphalt itself would have consumed some of the tissues of other than bones, and the asphalt itself would dissolve what was left, at the same time impregnating and beautifully preserving the saturated bones, rendering them dark brown and shiny.

The Great Energy Debate
Modern civilization is heavily dependent on energy. Without reliable power sources, we couldn’t operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy. Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward. Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap. The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. If they happen to have a meltdown, this could destroy the surrounding area for years to come. The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

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

My family consists of four people.There’s my father whose name is Jan, my mother whose name is Marie, my brother Peter and of course me. I have quite a large extended family as well but only the four of us live together in our apartment in a block of flats. My father is fifty-two years old, he works as an accountant in an insurance company. He is tall and slim, has got short brown and grey hair and blue eyes. My father likes gardening very much as well as listening to music and reading books about political science. His special hobbies are bird watching and travelling.

       Now I’ll describe my mother and my brother. My mother is forty-seven and she works as a nurse in a hospital. She is small and slim, has got short brown hair and green eyes. She likes bird watching and travelling too, so whenever my parents are able to they go some places interesting for nature watching. Since we we have a cottage with a garden they both spend a lot of time there. My brother is sixteen. He is slim and has short brown hair and blue eyes. He also attends high school. He is interested in computers and sports like football and hockey. He also spends a lot of time with his friends.

I have only one grandmother left still living. She is in pretty good health even at the age of seventy- eight so she still lives in her own flat. I enjoy spending time with her when I can. Both my grandfathers died from cancer because they are smokers, which was really a great tragedy because I didn’t get a chance to know them. My other grandmother died just a few years ago. I also have a lot of aunts, uncles, and cousines. The cousine I’m closest to is my uncle’s daughter Pauline. We have a lot in common because we are both eighteen and so we are good friends.

My parents have assigned  me certain duties around the house. I don’t mind helping out because everyone in a family should contribute in some way. I help with the washing up, the vacuuming and the shopping. Of course I also have to help keep my room tidy as well. My brother is responsible for the dusting and the mopping. He also has to clean his own room. Even though my brother and I sometimes fight about who has to do what job, we are still very close. I am also very close to my parents and I can rely on them to help me. My parents work together to keep our home well maintained and it seems they always have some projects or another that they are working on. They respect each other’s opinions and even if they disagree they can always come to a compromise. I hope in the future that I have a family like ours.
