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.

Read the following passage and choose the best answer (A, B, C, D):
Although only a small percentage of the electromagnetic radiation that is emitted by the Sun is ultraviolet (UV) radiation, the amount that is emitted would be enough to cause severe damage to most forms of life on Earth were it all to reach the surface of the Earth. Fortunately, all of the Sun’s ultraviolet radiation does not reach the Earth because of a layer of oxygen, called the ozone layer encircling the Earth in the stratosphere at an altitude of about 15 miles above the Earth. The ozone layer absorbs much of the Sun’s ultraviolet radiation and prevents it from reaching the Earth. Ozone is a form of oxygen in which each molecule consists of three atoms (O3) instead of the two atoms (O2) usually found in an oxygen molecule. Ozone forms in the stratosphere in a process that is initiated by ultraviolet radiation from the Sun. UV radiation from the Sun splits oxygen molecules with two atoms into free oxygen atoms, and each of these unattached oxygen atoms then joins up with an oxygen molecule to form ozone. UV radiation is also capable of splitting up ozone molecules; thus, ozone is constantly forming, splitting, and reforming in the stratosphere. When UV radiation is absorbed during the process of ozone formation and reformation, it is unable to reach Earth and cause damage there. Recently, however, the ozone layer over parts of the Earth has been diminishing. Chief among the culprits in the case of the disappearing ozone, those that are really responsible, are the chlorofluorocarbons (CFCs). CFCs meander up from Earth into the stratosphere, where they break down and release chlorine. The released chlorine reacts with ozone in the stratosphere to form chlorine monoxide (ClO) and oxygen (O2). The chlorine then becomes free to go through the cycle over and over again. One chlorine atom can, in fact, destroy hundreds of thousands of ozone molecules in this repetitious cycle, and the effects of this destructive process are now becoming evident.

Read the following passage and choose the best answer (A, B, C, D):
Although he created the game of basketball at the YMCA in Springfield, Massachusetts, Dr. James A. Naismith was a Canadian. Working as a physical education instructor at the International YMCA, now Springfield College, Dr. Naismith noticed a lack of interest in exercise among students during the wintertime. The New England winters were fierce, and the students balked at participating in outdoor activities. Naismith determined that a fast-moving game that could be played indoors would fill a void after the baseball and football seasons had ended. First he attempted to adapt outdoor games such as soccer and rugby to indoor play, but he soon found them unsuitable for confined areas. Finally, he determined that he would have to invent a game. In December of 1891, Dr. Naismith hung two old peach baskets as either end of the gymnasium at the school, and, using a soccer ball and nine players on each side, organized the first basketball game. The early rules allowed three points for each basket and made running with the ball a violation. Every time a goal was made, someone had to climb a ladder to retrieve the ball. Nevertheless, the game became popular. In less than a year, basketball was being played in both the United States and Canada. Five years later, a championship tournament was staged in New York City, which was won by the Brooklyn Central YMCA. The teams had already been reduced to seven players, and five became standard in the 1897 season. When basketball was introduced as a demonstration sport in the 1904 Olympic Games in St. Louis, it quickly spread throughout the world. In 1906, a metal hoop was used for the first time to replace the basket, but the name basketball has remained.

Saving the Rainforests
One of the hottest topics related to the environment is rainforests. Despite always being mentioned in the news, many people don’t know very much about these areas or understand why they are so important. The name “rainforest” actually does a pretty good job of describing what they are – tall forests that receive high amounts of precipitation. In a year, rainforests get between 250 to 450 centimetres of precipitation. There are two types of rainforests: tropical rainforests and temperate rainforests. Tropical rainforests are more plentiful and are located in warmer climates, while temperate rainforests are found in places where the weather is a bit milder. In terms of location, rainforests can be found on every continent with the exception of Antarctica. Although they only cover 6 percent of the Earth, over 50 percent of the Earth’s animal and plant species can be found there. Many biologists estimate that there are possibly millions of additional species present there that have yet to be discovered and classified. Over the years, rainforests have gained the nickname “the world’s pharmacy” because more than 25 percent of natural medicines were found there. Many herbs that are used to make medicines can only be found in rainforests. Rainforests are also home to several tribes that have lived off the land for thousands of years. During this time, they have survived by hunting animals and gathering fruits and vegetables. They also possess tremendous knowledge when it comes to crafting and applying medicines made from herbs and plants. Over time, their unique way of life has declined as they have come in contact with modern civilization. Despite their numerous benefits, rainforests have been disappearing at a rapid speed. As the Earth’s population continues to expand, developers have been cutting down their trees to create new lands for farming or urban projects. This could have unfortunate long-term effects on our planet. If deforestation continues at this rate, it is possible that a quarter of all species on the Earth may become extinct in the next 50 years. As it stands, plenty of damage has already occurred. West Africa has had 90 percent of its rainforests destroyed, while the island nation of Madagascar has eliminated 66 percent of its original rainforests as well. As a result, many charities have sprung up with the goal of purchasing and protecting the remaining rainforests. With their help, hopefully we can stop the destruction of one of the planet’s most vital assets.
3. Which of the following is NOT the feature of rainforests?

Most doctors and nurses have to work on a ____ once or twice a week at the hospital.

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.

Recent technological advances in manned and unmanned vehicles, along with breakthroughs in satellite technology and computer equipment, have overcome some of the limitations of divers and diving equipment for scientists doing research on the great oceans of the world. Without a vehicle, divers often became sluggish, and their mental concentration was severely limited. Because undersea pressure affects their speech organs, communication among divers has always been difficult or impossible. But today, most oceanographers avoid the use of vulnerable human divers, preferring to reduce the risk to human life and make direct observations by means of instruments that are lowered into the ocean, from samples take from the water, or from photographs made by orbiting satellites. Direct observations of the ocean floor can be made not only by divers but also by deep-diving submarines in the water and even by the technology of sophisticated aerial photography from vantage points above the surface of more than seven miles and cruise at depths of fifteen thousand feet. In addition, radio-equipped buoys can be operated by remote control in order to transmit information back to land-based laboratories via satellite. Particularly important for ocean study are data about water temperature, currents, and weather. Satellite photographs can show the distribution of sea ice, oil slicks, and cloud formations over the ocean. Maps created from satellite pictures can represent the temperature and the color of the ocean's surface, enabling researchers to study the ocean currents from laboratories on dry land. Furthermore, computers help oceanographers to collect, organize, and analyze data from submarines and satellites. By creating a model of the ocean's movement and characteristics, scientists can predict the patterns and possible effects of the ocean on the environment.
Recently, many oceanographers have been relying more on satellites and computers than on research ships or even submarine vehicles because they can supply a greater range of information more quickly and more effectively. Some of humankind's most serious problems, especially those concerning energy and food, may be solved with the help of observations made possible by this new technology.

A Microchip in Your Body
In 1998, a British scientist named Kevin Warwick did an experiment. He inserted a small microchip into his left arm. He used the microchip to turn on lights, work with his computer, and even start the water for his hath. After only nine days, Warwick removed the microchip from his arm. Nine days is not a long time, but it was enough to give the world a very important message. It is possible to have a microchip in your body. Many people think that someday, we all will have microchips. There are all kinds of things that a microchip could do. It could be useful for simple, everyday things. You might not have to carry keys, because you could use your microchip to open the front door of your house. You might not need cash, because you could use your microchip to buy things. A microchip might be able to do more important things. For example, a microchip could contain all of your important health information. If you had an emergency and wert to hospital, doctors could read your microchip and learn all of your health history. Some scientists even believe that someday a microchip could help cure diseases. Many people dislike the idea of a microchip in their body. They have a lot of concerns. Is it safe? Could a microchip make you sick? Besides, would other people be able to read your microchip and steal your personal information? People are especially worried about personal freedom. This is probably the biggest reason why so many people are against these microchips. What if your government could use your microchip to watch you? What if your government could use your microchip to find your location? Do you want the government to have that information about you? Again, for most people the answer is “no". Nobody has microchips in their body yet. We don't know if this will ever happen. If we ever do have microchips, we don't know what they would look like or what they would do. What do you think? Would you like to have a microchip inserted into your body?

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.

Some technological developments are the results of years of diligent work. Others are stumbled upon by accident. The discovery of X-rays is in the second category. In 1895, X-ray radiation was accidentally discovered by a physicist named Wilhelm Rontgen, while he was working in his lab. Rontgen discovery greatly advanced medical science. One night in 1895, Wilhelm Rontgen was working with an electric device called a Crookes tube. A Crookes tube is a glass tube with metal components inside it. When turned on, the tube produces a stream of electrons. Rontgen and other scientists observed a new form of energy escaping from the front end of the Crookes tube. Rontgen wanted to be the first to discover this new mysterious energy. To do this, he needed to make sure the tube was covered with black cardboard. This would make the room completely dark and allow him to better see this new form of energy. Rontgen was hoping to observe this new energy on a special screen that would be placed right in front of the Crookes tube. Amazingly, before the screen was placed near the Crookes tube, Rontgen already noticed the screen was glowing. He bought the screen closer, and the glow became brighter. (1) He then placed a book between the end of the tube and the screen-the glow was still there. (2) Rontgen realized that a new and different form of radiation must be causing the screen to glow. (3) As he didn't know what kind of radiation it was, he named it "X". (4) Rontgen soon started studying the new type of radiation. He designed experiments which allowed him to test how far X- rays could penetrate. He also had the bright idea of trying to take photographs with X-rays. One day, he tested his theories by asking his wife to put her hand between a photographic plate and a Crookes Tube. Sure enough, the resulting image of the bones in his wife's hand was the first ever X-ray photograph of the human body. After taking that first photograph, Rontgen understood how X-rays could benefit doctors and patients. He shared his discovery, and soon X-ray machines were appearing in hospitals. X-rays were very useful for medicine because they let doctors see a patient's bones. If a patient had a broken bone, it was made visible by the X-ray image. This let doctors know the right way to repair the fracture. Wilhelm Rontgen's accidental discovery has now been helping people for over one hundred years. Thanks to X-rays, broken bones can be repaired reliably and effectively. We should be grateful to Wilhelm Rontgen for making his discovery freely available and greatly advancing medical science. Because of this, we humans are able to live longer, healthier lives.

Explosions in the Sky
If you attend a major outdoor event in the evening, whether it is in Paris, Beijing, or New York City, there is a good chance that it will end in a sensational way. After all of the other activities have concluded, the sky will be lit up by a colourful firework display. Although the show may only last for a few minutes, during that time every eye will look on with amazement as they work their magic in the air. Fireworks were invented in the seventh century by the Chinese. They were quickly absorbed into the culture and became a part of many celebratory events and festivals. Eventually, emperors would organize large firework displays to entertain and impress their subjects. Fireworks didn’t become big in Europe until the mid-17th century. People became interested in fireworks after reading accounts from monks and travellers who saw them while in China. Once they did arrive, it was obvious they were there to stay. Fireworks were frequently paired with triumphant classical symphonies to celebrate the end of wars and other great victories. As time went on, the fireworks continued to evolve and get better in many ways. Fireworks now come in every colour imaginable. The colour comes from different chemicals that are placed inside of each firework. Thanks to modern technology, it is also possible to create firework arrangements in the shape of hearts, smiley faces, and even the planet Saturn. This is because of the way that the aerial shells, or casings, of fireworks are constructed. The cases are packed with exploding pellets and a piece of cardboard. The cardboard enables the designers to arrange the pellets in pattern or shape of the object of their choice. The first time this technology was used was in Washington DC, during a celebration to welcome home American troops who fought in the Gulf War. The visual aspect is only part of the reason fireworks are appealing. The sounds that fireworks make also add a healthy dose of excitement to the display. There are several noises that fireworks can make. The most common is the “bang” which sounds a lot like a gunshot. Fireworks can also crackle, hum, and whistle as they streak across the night sky. The world’s largest firework show was held in Kuwait in 2012. 77,282 fireworks exploded during the incredible 64-minute show. But with people’s love for fireworks at an all-time high, who knows how long that record will last?
