There are books with fairy tails in many countries. Often the same stories are known and repeated in many languages. Some of the things that happens in these stories are remarkable, although not as remarkable as things that are truly happening in medicine and science today.
Most fairy tails begin with “Once upon a time” and end with “They lived happily ever after”, so we will begin in the same way.
Once upon a time there was a girl calls Cinderella who did all the work in the kitchen while her lazy sister did nothing.
One night, her sister went to a ball at the palace. Cinderella was left home, very sad. After a time her fairy godmother appeared and told Cinderella that she could go to the ball- but to return home by midnight.
So she went to the ball in a beautiful dress in a wonderful coach. She danced with the prince but at midnight she ran back home, leaving one of her shoes on the floor. The prince wanted to see her again and went to every house in the capital until he found that the shoe was the right size for Cinderella. She and the price were married and lived happily ever after.

Most fairy tails begin with “Once upon a time” and end with “They lived happily ever after”, so we will begin_______________.

BASKETBALL
1. 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 a fast-moving game that could be played indoors would fill a void after the baseball and football seasons had ended.
2. 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.
3. In December of 1891, Dr. Naismith hung two old peach baskets at 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 violation. Every time a goal was made, someone had to climb a ladder to retrieve the ball.
4. 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.
5. The teams had already been reduced to seven players, and five became standard in  1897 season. When basketball was introduced as a demonstration sport in the 1904 Olympic Games in St. Luis, 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.

In which paragraph does the author discuss the first basketball championship tournament?

Many of the most damaging and life-threaling types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or “Nowcasts”, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

The word “subtle” is closest in meaning to ________.

Light from a living plant or animal is called bioluminescence, or cold light, to distinguish it from incandescence or heat-generating light. Life forms could not produce incandescent light without being burned. Their light is produced in chemicals combining in such a way that little or no measurable heat is produced, and the life forms generating it are unharmed. Although bioluminescence is a relatively complicated process, it can be reduced to simple terms. Living light occurs when luciferin and oxygen combine in the presence of luciferase. In a few cases, fireflies the most common, an additional compound called ATP is required.
The earliest recorded experiments with bioluminescence in the late 1800s are attributed to Raphael Dubois, who extracted a luminous fluid from a clam, observing that it continued to glow in the test tube for several minutes. He named the substance luciferin, which means “the bearer of life”. In further research, Dubois discovered that several chemicals were required for bioluminescence to occur. In his notes, it was recorded that a second important substance, which he called luciferase, was always present. In later study of small, luminous sea creatures, Newton Harley concluded that luciferin was composed of carbon, hydrosen, and oxygen, which are the building blocks of all living cells. He also proved that there are a variety of luciferin and luciferase, specific to the plants and animals that produce them.
Much remains unknown, but many scientists who are studying bioluminescence now believe that the origin of the phenomenon may be traced to a time when there was no oxygen in the Earth’s atmosphere. When oxygen was gradually introduced to the atmosphere, it was actually poisonous to life forms, plants and animals produced light to use up the oxygen in a gradual but necessary adaptation. It is speculated that millions of years ago, all life may have produced light to survive. As the millennia passed, life forms on Earth became tolerant of, and finally dependent on oxygen, and the adaptation that produced bioluminescence was no longer necessary, but some primitive plants and animals continued to use the light for new functions such as mating or attracting prey.

Bioluminescence is described as all of the following EXCEPT ________.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

I’m standing on a sidewalk in the early morning. The great avenues of Paris are silent, and the shops are closed. Suddenly, a couple appeared from a hole in the sidewalk. Mud covers their boots. They place the iron cover over the hole and run down the street, smiling. The couple had been exploring the tunnels beneath the city.

When Romans occupied Paris, they cut down stone from deep within the earth to build their city. Later, the French used more stone to construct the Notre Dame Cathedral. This left huge underground tunnels upon which part of the city now. Once used for growing mushrooms and as a hiding place, today they are mostly forgotten, except by "cataphiles" - those who love to go down into the tunnels below Paris, even though it is actually not permitted.

In the 70s and 80s, it is easier to enter the tunnels because there were many more open entrances through forgotten doorways and into catacombs - rooms filled with bones. The bones had been moved into the tunnels to solve the problem crowded cemeteries. By the end of the 1980s, most of the entrances were shut and police regularly walked the tunnels. However, there are still cataphiles, like the couple I saw that morning, and for those who dare, the underground is an exciting place to meet, party, perform for each other or create art.

My own experience began beneath the old Paris opera house, where sewer workers showed me a 55-meter-long underground pond, a pond that actually had fish in it! Later, at France's national bank, officials guided me below to an amazing room filled with 2,600 tons of gold.

As cataphiles are the best guides, I then asked one of the cataphiles to give me a tour. Descending into the underground through a secret entrance beneath a bridge, we walked for hours through catacombs, and galleries of huge, bright paintings. The cataphile told me "Many people come down here to party, some to paint. Some people to destroy or to create or to explore. We do what we want, We don't have rules..."

When I saw her name on the screen, it took me right back to the moment she had moved away with her family ten years before. We had been such close friends at primary school. To begin with, she and I had not hit it off, perhaps because we were both timid. We had quickly got over that, though, and as time went on, we had become really good friends, until you almost never saw one of us without the other.

And now after so much time apart, there was her name. She had sent me a friend request. I knew she had been living abroad, and her profile picture showed her on the beach. I had been expecting her to look different after ten years. The girl in the photo was the same old Lauren, though.

Nowadays, it is easy to find old friends thanks to social networking sites. There are lots of stories about long lost friends getting back in touch after years apart. It was odd because I had been thinking about our friendship too and now here she was!

She told me about the place where she had been living for the past ten years, and I told her about things that had happened to me. Before long, the years melted away and we were the same two girls who had spent so much time together. Of course, true friends are loyal and listen to you when you are down. And they are the people you have fun with. But deep down, I realised that the truest friends are those you are most yourself with. And that is something that never changes. That is what Lauren and I learned that day, the day we realised our friendship was so precious and had never really ended in the first place.

The word “they” in paragraph 4 refers to __________.

Read the following passage and choose the correct answer to each of the questions.

The word "robot" first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer, Isaac Asimov, wrote a series of stories about robots and invented the term 'robotics', the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produced the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.

These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machines, with metal "arms" or "hands". Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.

Outside of industry, robots have also been developed and put into use by governments and scientists in situations where humans might be in danger. For example, they can be sent in to investigate an unexploded bomb or an accident at a nuclear power plant. Researchers also use robots to collect samples of hot rocks or gases in active volcanoes. In space exploration, robots have performed many key tasks where humans could not be present, such as on the surface of Mars. In 2004, two robotic Rovers, small six-wheeled computerized cars, were sent to Mars.

What can be inferred from the passage about robots?

Poles Apart
Many are surprised to learn that Antarctica is nearly twice the size of the United States. The name Antarctica was coined to mean "opposite to the Arctic." It is just that in many ways. Antarctica is a high, ice-covered landmass. In the Arctic the landmasses are grouped around the ice-covered Arctic Ocean.
Largely because of this difference, the climate of the two areas is very different. Antarctica is the coldest area in the world. On the average it is about 30 degrees colder than the Arctic. At the South Pole, nearly 10.000 feet high, monthly mean temperatures run well below zero. Only in coastal regions do temperatures sometimes rise about freezing in the summer (December to March). In contrast, near the North Pole monthly mean temperatures often rise above freezing. 
At both poles, daily temperatures may drop far below the monthly mean. At the American South Pole Station, winter temperatures sometimes fall below -100 degrees Fahrenheit. Elsewhere, on higher parts of the south polar plateau, even lower temperatures are recorded.
A temperature of -127 degrees Fahrenheit was measured in August 1960. It is the world's record low temperature.
Partly because of this climatic difference, the land animals and plants of the two regions are very different. On the continent of Antarctica, there are very few plants. In the Arctic there are many plants. In some of the few ice-free areas of Antarctica, mosses, lichens, and algae are found. Penguins populate Antarctic coastlines but do not exist in the Arctic. The land animals of the Arctic are foxes, bears, reindeer, and lemmings. These animals are unknown in the Antarctic. Old rock layers show that this "oppositeness" between north and south extends far back into the early chapters of earth history.
Ice is the great feature of Antarctica. More than 4.5 million square miles of ice sheet cover the area. Great rivers of ice, called glaciers, push down the mountains. Antarctica is the storehouse of about 85 percent of the total world supply of ice. 
The icecap is very thick, averaging nearly 8,000 feet. At one spot, scientists have found the distance from the surface to the rock underneath the ice to be more than 13,000 feet.
If this great volume of ice were to melt, the volume of the world oceans would increase, and sea level would rise. Extreme atmospheric changes would have to take place for this to happen.

Some areas of Antarctica are _________.

The concept of traffic-free shopping areas goes back a long time. During the Middle Ages, traffic-tree shopping areas were built in Middle Eastern countries to allow people to shop in comfort and, more importantly, safety. As far back as 2000 years ago, road traffic was banned from central Rome during the day to allow for the free movement of pedestrians.

The modern, traffic-free shopping street was born in Europe in the 1960s, when both city population and car ownership increased rapidly. Dirty exhaust from cars and the risks involved in crossing the road were beginning to make shopping an unpleasant and dangerous experience. Many believed the time was right experimenting with car-free streets, and shopping areas seemed the best place to start.

At first, there was resistance from shopkeepers. They argued that people would avoid streets if they unable to get to them in their cars. When the first streets in Europe were closed to traffic, there were noisy demonstrations, as many shopkeepers predicted they would lose customers.

With the arrival of the traffic-free shopping street, many shops, especially those selling things clothes, food and smaller luxury items, prospered. Unfortunately, shops selling furniture and larger electrical appliances actually saw their sales drop. Many of these were forced to move elsewhere, away from centre.
