There is very little documentation about the origins of water polo. It is known, however, that the sport originated in the rivers and lakes of mid-19th century England as an aquatic version of rugby. Early games used an inflated rubber ball that came from India known as a "pulu" (the single Indian word for all "balls"). Pronounced "polo" by the English, both the game and the ball became known as "water polo". To attract more spectators to swimming exhibitions, the London Swimming Association designed a set of water polo rules for indoor swimming pools in 1870. At first, players scored by planting the ball on the end of the pool with both hands. A favorite trick of the players was to place the five-to-nine inch rubber ball inside their swimming suit and dive under the murky water, they would then appear again as close to the goal as possible. The introduction of the rules by Scottish players changed the nature of water polo. It became a game that emphasized swimming, speed and passing. Scottish rules moved from a rugby variant to a soccer style of play. Goals became a cage of 10x 3 feet and a goal could be scored by being thrown. Players could only be tackled when they "held" the ball and the ball could no longer be taken under water. The small rubber ball was replaced by a leather soccer ball. If the player came up too near the goal, he was promptly jumped on by the goalie, who was permitted to stand on the pool deck. Games were often nothing more than gang fights in the water as players ignored the ball, preferring underwater wrestling matches that usually ended with one man floating to the surface unconscious. Water polo was first played in the USA in 1888. The game featured the old rugby style of play which resembled American football in the water. "American style" water polo became very popular and by the late 1890s was played in such venues as Madison Square Garden and Boston's Mechanics Hall, attracting 14,000 spectators to national championship games.

In water polo, the players score a goal by _______.

   Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication – having a mobile phone shows that they are cool and connected.

   The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

   On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn’t remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer’s doctor didn’t agree.

   What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

   As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it’s wise not to use your mobile phone too often.

Synchronized swimming is a hybrid form of swimming, dance and figure skating which consists of swimmers (either individuals, duets, trios, teams or combos) performing a synchronized routine of elaborate and dramatic moves in the water, accompanied by music. Synchronized swimming demands advanced water skills, and requires strength, endurance, flexibility, grace, artistry and precise timing, not to mention exceptional breath control while upside down underwater.

Developed in the early 1900s in Canada, it is a sport performed almost exclusively by women, although there is some participation by men. In its early form it was sometimes known as “water ballet”.

It is a Summer Olympic Games sport. First demonstrated in 1952, it has been an official event since 1984. Olympic and World Championship competition is not currently open to men, but other international and national competitions allow male competitors. Both USA Synchro and Synchro Canada allow men to compete with women. In competition, competitors show off their strength, flexibility, and aerobic endurance required to perform difficult routines. Swimmers perform two routines for the judges, one technical and one free.

Synchronized swimming is a harmonious combination of swimming, dance and figure skating.

For more than six million American children, coming home after school means coming  back to an empty house. Some deal with the situation by watching TV. Some may hide. But all of  them have something in common. They spend part of each day alone. They are called “latchkey children”. They are children who look after themselves while their parents work. And their bad  condition has become a subject of concern. 
Lynette Long was once the principal of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was  constantly telling them to put the keys inside shirts. There were so many keys; it never came to  my mind what they meant.” Slowly, she learned that they were house keys. She and her husband began talking to the children who had keys. They learned of the effect working couples and single parents were having on their children. Fear was the biggest problem faced by children at home alone. One in three latchkey children the Longs talked to reported being  frightened. Many had nightmares and were worried about their own safety. The most common way latchkey children deal with their fears is by hiding. They may hide  in a shower stall, under a bed or in a closet. The second is TV. They often turn the volume up. It’s  hard to get statistics on latchkey children, the Longs have learned. Most parents are slow to admit  that they leave their children alone

What is the most common way for latchkey children to deal with fears?

The excitement of snorkelling in a clear tropical sea is hard to explain to someone who hasn't done it. If you expect to have the opportunity of trying it when on holiday, it is well worth bringing a snorkel if you can get hold of one. Experts now recommend a separate breathing tube.

Many swimmers take a deep breath before diving with a snorkel. This is a mistake, because it makes the body so light that you dive with difficulty. It is best to take a couple of deep breaths and then a normal relaxed breath in order to breathe in enough for dive. Don't take repeated deep breaths before diving because this can lead to shortage of oxygen, which causes unconsciousness without warning.

The backs of many snorkellers get badly burnt, for the snorkellers are so involved in the world below they forget about the dangers of sunburn. The sea does not protect your back from the rays of the sun, and it is best to wear a T-shirt. Snorkellers should also consider wearing shoes (or slippers), which may protect their feet from cuts from sharp rocks which can easily become infected.

Why is taking a deep breath before diving a mistake?

Walt Disney was born in 1901 in Chicago, but soon moved to a small farm near Marceline, Missouri. From this rural and rather humble beginning he later became one of the most famous and beloved motion-picture producers in history. Although he died in 1966, his name and artistic legacy continue to influence the lives of millions of people throughout the world.
After several years of barely making ends meet as a cartoon artist operating from his Los Angeles garage, Disney had his first success in 1928, with his release of a Mickey Mouse cartoon. Throughout the next decade, he continued to produce a number of cartoons, and develop more of his highly profitable and enduring creations, such as Donald Duck and Pluto. In the late 1930s, he issued full-length cartoon film. Snow White became an instant commercial and critical success. This was only the first of many films, both animated and not, produced by Disney and his studio.
But as renowned as Disney name is for cartoon and monies, it is probably best known for a string of spectacular amusement and theme parks. Starting with California's Disneyland in 1955 and culminating with the fantastically successful Disney World and EPCOT Center in Florida, Disney became a household name. In recent years, the theme park concept became international, with openings in Toyo and Paris. With the continuing success of Disney, the creation of future theme park are under discussion.

In future years it is most likely that _______.

The peregrine falcon, a predatory bird indigenous to North America, was once in danger of extinction. In the 1960s, scientists discovered byproducts of the pesticide DDT in the birds' eggs, which caused them to be too soft to survive. The use of the pesticide had been banned in the United States, but the falcons were eating migratory birds from other places where DDT was still used. In order to increase the survival rate, scientists were raising the birds in laboratories and then releasing them into mountainous areas. This practice achieved only moderate success, however, because many of the birds raised in captivity could not survive in the wild.

There is now, however, a new alternative to releases in the wild. A falcon that has been given the name Scarlett chose to make her home on a ledge of the 33rd floor of a Baltimore, Maryland, office building rather than in the wild, and, to the surprise of the scientists, she has managed to live quite well in the city. Following this example, programs have been initiated that release birds like Scarlett into cities rather than into their natural wild habitat. These urban releases are becoming a common way to strengthen the species. Urban homes have several benefits for the birds that wild spots do not. First, there is an abundance of pigeons and small birds as food sources. The peregrine in the city is also protected from its main predator, the great horned owl. Urban release programs have been very successful in reestablishing the peregrine falcons along the East Coast. Though they are still an endangered species, their numbers increased from about 60 nesting pairs in 1975 to about 700 pairs in 1992. In another decade the species may flourish again, this time without human help.

A study was set up to examine the old marriage advice about whether it's more important to be happy or to be right. Couples therapists sometimes suggest that in an attempt to avoid constant arguments, spouses weigh up whether pressing the point is worth the misery of marital discord. The researchers from the University of Auckland noticed that many of their patients were adding stress to their lives by insisting on being right, even when it worked against their well-being.
The researchers then found a couple who were willing to record their quality of life on a scale of 1 to 10. They told the man, who wanted to be happy more than right, about the purpose of the study and asked him to agree with every opinion and request his wife had without complaint, even when he profoundly didn't agree. The wife was not informed of the purpose of the study and just asked to record her quality of life.
Things went rapidly downhill for the couple. The man's quality-of-life scores fell, from 7 to 3, over the course of the experiment. The wife's scores rose modestly, from 8 to 8.5, before she became hostile to the idea of recording the scores. Rather than creating harmony, the husband's agreeableness led to the wife becoming increasingly critical of what he did and said (in the husband's opinion). After 12 days he broke down, and the study was called off because of severe adverse outcomes."
The researchers concluded, shockingly, that humans need to be right and acknowledged as right, at least some of the time, to be happy. They also noted this was further proof that if given too much power, humans tend to "assume the alpha position and, as with chimpanzees, they become very aggressive and dangerous." It is often said that there can be no peace without justice, and that's true of domestic sphere.
Obviously the results are to be taken with extreme caution, since this was just one couple with who-knows-what underlying issues beforehand. But the study's chief author, Dr. Bruce Arroll, maintains that the question of happiness vs. rightness, theoretically, could be settled by scientific inquiry with a wider sample. "This would include a randomized controlled trial,” he says. "However, we would be reluctant to do the definitive study because of the concern about divorce."

The word "They" in paragraph 4 refers to _______.

Underwater hockey is a non-contact sport in which two teams compete to maneuver a puck across the bottom of a swimming pool into goals. 
Players wear a diving mask, fins, speedos and a snorkel for play_ Safety gear includes a water polo style cap, a mouthguard, and a glove for the playing hand (to protect against pool-bottom abrasion and, in some designs, knuckle protection against puck impact). Because current rules permit a player to switch the stick between hands mid-play, players may choose to wear a protective glove on both hands. The stick is quite short (not more than 350 mm in length, including the handle) and is colored white or black to indicate the player's team.
Two teams of up to ten players compete, with six players on each team in play at once. Substitution happens continually from a substitution area, which may be on deck or in the water outside the playing area, depending on tourna went rules. Before the start of play the puck is placed in the middle of the pool, and the players wait in the water, touching the wall above the goals they are defending. At the start-of-play signal, in- play members of both teams are free to swim anywhere in the play area and try to score by sending the puck into the opponents' goal. Play continues until either a goal is scored, and players return to their wall to start a new point, or a break in play is signaled by a referee. 
There are a number of penalties described in the official underwater hockey rules, ranging from use of the stick against something (or someone) other than the puck or the playing surface, playing or stopping the puck with something other than the stick, and "screening". If the penalty is minor, referees award an advantage puck - the team that committed the foul is pushed back 3 meters from the puck, while the other team gets a free possession. For major penalties, such as a dangerous pass or intentional or repeated fouls, the referees may eject. players for a specified period of time or the remainder of the game. A defender committing a serious foul sufficiently close to his own goal may be penalized by the award of a point to the fouled player's team.
Games consist of two halves, typically ten to fifteen minutes in length (depending on tournament rules; 15 minutes at world championship tournaments) and a short half time interval. At half time the two teams switch ends.

What happens to the player who commits an intentional foul?

   Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described.

   Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the levels of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events.

   It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population.

   Finally, it is worth noting that the terms "standard", "colloquial" and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.

   In the 1960s, The Beatles were probably the most famous pop group in the whole world. Since then, there have been a great many groups that have achieved enormous fame, so it is perhaps difficult now to imagine how sensational The Beatles were at that time. They were four boys from the north of England and none of them had any training in music. They started by performing and recording songs by black Americans and they had some success with these songs. Then they started writing their own songs and that was when they became really popular. The Beatles changed pop music. They were the first pop group to achieve great success from songs they had written themselves. After that it became common for groups and singers to write their own songs. The Beatles did not have a long career. Their first hit record was in 1963 and they split up in 1970. They stopped doing live performances in 1966 because it had become too dangerous for them - their fans were so excited that they surrounded them and tried to take their clothes as souvenirs! However, today some of their songs remain as famous as they were when they first came out. Throughout the world, many people can sing part of a Beatles song if you ask them.

Marcel Bich, a French manufacturer of traditional ink pens, was the man turning the ballpoint pen into an item that today almost anyone can afford. Bich was shocked at the poor quality of the ballpoint pens that were available, and also at their high cost. However, he recognised that the ballpoint was a firmly established invention, and he decided to design a cheap pen that worked well and would be commercially successful.
Bich went to the Biro brothers and asked them if he could use the design of their original invention in one of his own pens. In return, he offered to pay them every time he sold a pen. Then, for two years, Bich studied the detailed construction of every ballpoint pen that was being sold, often working with a microscope.
By 1950, he was ready to introduce his new wonder: a plastic pen with a clear barrel that wrote smoothly, did not leak and only cost a few cents. He called it the 'Bic Cristal'. The ballpoint pen had finally become a practical writing instrument. The public liked it immediately, and today it is as common as the pencil. In Britain, they are still called Biros, and many Bic models also say 'Biro' on the side of the pen, to remind people of their original inventors.
Bich became extremely wealthy thanks to his invention, which had worldwide appeal. Over the next 60 years his company, Société Bic, opened factories all over the world and expanded its range of inexpensive products. Today, Bic is as famous for its lighters and razors as it is for its pens, and you can even buy a Bic mobile phone.

According to the passage, which of the following is NOT mentioned as products of Bich's company?
