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.

Why did Naismith decide to invent basketball?

What does this passage mainly discuss?

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.

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..."

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.

   Mickey Mantle was one of the greatest baseball players of all time. He played for the New York Yankees in their years of glory. From the time Mantle began to play professionally in 1951 to his last year in 1968, baseball was the most popular game in the United States. For many people, Mantle symbolized the hope, prosperity, and confidence of America at that time.

   Mantle was a fast and powerful player, a “switch-hitter” who could bat both right-handed and lefthanded. He won game after game, one World Series championship after another, for his team. He was a wonderful athlete, but this alone cannot explain America’s fascination with him.

   Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle.

   But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death.

   It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63.

What is the main idea of the passage?

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.

The word “ball” in the first sentence means ________________.

An important point to remember if you like spending time out in the open air is that the human head doesn't work very well outdoors if it becomes too hot, cold or wet.

In cold climates, the problem is that the head is (17)           heat all the time. As much as fifty to sixty per cent of your body‟s heat is lost through the head and neck, (18)      on which scientist  you believe. Clearly this heat loss needs to be prevented, but it‟s important to remember that hats don‟t actually keep you warm, they simply stop heat escaping.
Just as important is the need to protect your neck from the effects of bright sunlight, and the brim of your hat will do this. If you prefer a baseball cap, (19)       buying one that has a drop down tail at the back to stop your neck getting sunburnt.
And in wet weather  (20)         ,  hats are often more practical than  pooling up the hood of your waterproof coat because when you turn your head, the hat goes with you, whereas the hood usually does not.

From the next year, every student in their final rear at our school will study for a compulsory Diploma of Practical Achievement. This will be in addition to the normal examinations. Up to now, the course has been optional, but from now on every student must (31)        it.
The aim is to (32)   students with "life skills", which the Diploma divides into eight categories. These cover a range of things relevant to life beyond school, from sending an e-mail to giving presentation  to  an  audience.  Under  the  heading     "survival",  (33)      ,  students   can learn  car mainternance, first aid and cooking. We have discovered that many students cannot do simple things such as mend a puncture or boil an egg. At the other extreme, the Diploma includes such things as how to design a webpage and how to cope if someone has a heart attack. It has been called a " Diploma in Common Sense".
On the course, students will not be taught in the traditional (34)  
  , but rather will be guided and encouraged to do things for themselves. This is above all a practical "hand-on" course. To a greater or lesser extent, good schools have always tried to (35)        these skills. Unfortunately, students have not always shown much interest because such skills are not directly related to passing exams for higher education. We hope this will change now that we have a proper course that will lead to a recognised diploma.

Machines already perform a lot of tasks that were usually done by humans, such as building cars, doing complex calculations, and even marking exam papers. But now it seems that ever more intelligent machines are straying into areas where we never envisaged they would go. We have always taken pride in having a unique kind of intelligence that machines could never match, one which allows us to think of new ideas and produce creative and artistic works. But it seems that even here, computers are lining up to compete with us.

Machines can easily be trained to do the physical work of producing art. About ten years ago, a painting robot known as e-David was created at a university in Germany. And recently in New York, the painting ‘Portrait of Edmond de Belamy' has been auctioned for nearly half a million dollars. What made it a bit unusual was that the idea, and the image itself, was produced entirely by a computer. A group of young French artists gave instructions to the computer, aiming simply to show that computers can be creative.

Some artists are now working with computers to produce a new kind of art. Computer-generated works of art are certainly interesting, and make us think about the limits of what machines can and cannot do. But not everyone would accept that they qualify as art. Some enthusiasts would argue they do, and the collectors willing to pay high prices for these works would suggest there is definitely a market for computer art. Others, however, would disagree.

Many 'real' artists would claim that art is an expression of human intelligence and human emotions. More importantly, it is about a desire to communicate with other people. These things, they argue, are part of being human and can never be produced by a machine.
