Article: Mr. Smith lived in a small village. He grew vegetables. Years ago he found work in a big city and moved there with his family. On the first Saturday in their new home, Mr. Smith took his new car out of the garage and washed it. A man came at the moment. When he saw Mr. Smith's new car, he stopped and looked at it for a few minutes. Then Mr. Smith turned and saw him. The man said, "That's a nice car. Is it yours?" "Sometimes," Smith answered with a smile. "Sometimes?" The man said. "What do you mean?" "Well," answered Smith slowly, "When there's a party in town, it is my daughter's, Mary. When there's a football game, it's my son's, John. After I wash it, and it looks really nice and clean, it's my wife's. And when it needs gas, it's mine."

Article: How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words. The power of words, then, lies in their association--the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can _ his meaning in words which sing like music and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and impolite.
Question: Where does the real power of the words come from?
Options: (A) From the words themselves. (B) From their characteristics. (C) From their curiosity. (D) From their association.

Article: (The Daily Mail) David Thomas failed all his maths exams and left school with no qualifications, yet this 30 - year - old fire - fighter has just gone into the Guinness Book of Records by reciting from memory 22,500 digits of the mathematical constant, pi(p). After five months of training, in which he spent ten hours a day memorizing a quarter of a million digits, David Thomas took part in a 16 - hour mental battle.Witnesses watched in awe as Thomas set a new European record, earning the title 'Most Powerful Memory in the Western Hemisphere'. David says, "When I was at school I was hopeless.I could' t remember anything, but now I can remember more facts than anyone in Europe." So how does Thomas do it? "One night I was watching a TV programme about an interview with a man called Dominic O'Brien, who had been the world memory champion five times.He used to be a gambler, and he wasn't particularly successful until he developed his own mnemonics, or mental memory aid, for each card in order to remember which cards had already been dealt and which ones hadn't." Thomas became fascinated by O'Brien's theory that anyone can improve their memory by using specialized techniques.These techniques involve linking everything to familiar people or objects. "If you want to remember a phone number for example, you have to give the numbers life.Sometimes I associate a number with a person.Number 10 for me is always the Prime Minister (who lives at number 10 Downing Street) ," explained David.If David is trying to remember facts he also links them to an image."For instance, if I was trying to memorize the name 'Tom Cruise' , I would think of his film Top Cun, and that leads me to images of guns and cruise missiles." is soon going to appear on TV's Record Breakers, and this week he is teaching memory training and speed - writing at Huddersfield University.His fees are PS600 a day.He is sure that the future holds a lot more for him than a job as a fire - fighter.
