A magician named Dedi of Dedsnefu was reported to have performed for the pharaoh, or the king. He was also known to have entertained the slaves who built the pyramids. The “Cups and Balls” trick which he was particularly good at is still performed by magicians all over the world today.The ancient Greeks and Romans were also fascinated by the idea of magic. Actually, one of their main interests was the art of deception. This explains why at that time the priests even built magic devices into their temples. These devices made it possible for doors to open by themselves and wine to flow magically out of statues’ mouths. This was done mainly to convince people that the priests were powerful.Magic, however, was not well accepted before the 1800s. Magicians were thought of as freaks and were only allowed to perform in a circus. It was in the 19th century that the magician Robert Houdin came along and changed people’s views and attitudes about magic. It was also because of Robert Houdin that many magicians were able to add Dr. or MD to their names. Today magicians try hard to find new ways to show their practiced skills. Magic is now entertainment for families all over the world.44. What is the best title for the passage?92學年度第 6 頁英文考科共7 頁(A) Magical Tricks (B) A Great Magician(C) Magic as Entertainment (D) The History of Magic- 6 -第7 頁92學年度共7 頁英文考科45.

One is called “doctor medicine,” or “scientific medicine.”Scientific doctors try to observe sicknesses, look for logical patterns, and then find out how the human body works. From there they figure out what treatments may work. This kind of medicine is believed to date from the 4th century BC. Although nowadays it is successful, in the ancient world this approach probably did not cure many patients.A second kind of medicine is called “natural cures,” or “folk med icine,” in which less educated people try to cure sicknesses with various herbs. These folk healers also use observation and logic, but they are not so aware of it. They try things until they find something that seems to work, and then they keep doing that. Folk medicine flourished long before the development of scientific medicine and was more successful in ancient times than doctor medicine.The third kind is called “health spas,” or “faith healing.” Sometimes this may be as simple as touching the holy man and being immediately healed. Other times, a magician may make you a magic charm, or say a spell, to cure you. Some religious groups organize special healing shrines for the sick. In these places people rest, get plenty of sleep, eat healthy food, drink water instead of wine, and exercise in various ways. They also talk to the priests and pray to the gods. If you are feeling depressed or you have been working too hard, going to these places may be just the right thing to make you feel better.48. Doctor medicine __________.(A) has a longer history than folk medicine(B) has been practiced for around 1,600 years(C) bases its treatments on observation and logic(D) was very successful in curing sicknesses in ancient times- 7 -92學年度第8 頁英文考科共7 頁49.

The author’s primary purpose in this passage is to __________.(A) describe different types of medicine(B) argue for the importance of medicine in health care(C) show the crucial role religion plays in medical treatments(D) compare the educational background of three different types of patients52-55為題組Today's teen consumer market is the most profitable it has ever been. Even though 65% of teens claim that they rely on themselves for their fashion ideas, it is estimated that less than 20% of the teen population is innovative enough to drive fashion trends, according to a recent study by a marketing firm. Marketers recognize this fact and often use elements of youth culture to promote their products. Perhaps one of the best examples is their use of hip-hop culture. It is reported that hip-hop fashion alone generates $750 million to $1 billion annually. Sales of rap music and videos each exceed that amount.Rap's rise and sustained global popularity is a good illustration of how influential youth culture is on youth attitudes and behavior. Remember when Madonna hit the charts with her bra in full view while singing about "virginity"? Soon after that, adolescent girls around the world began wearing their underwear outside their clothes.Fashion designer Tommy Hilfiger was fully aware of the power of youth culture. He marketed his brand by giving clothes to famous MTV stars and featuring teen stars in his print ads. Picking up on teens' interest in computer games, Hilfiger sponsored a Nintendo competition and installed Nintendo terminals in his stores. The payoff? Teens rated Hilfiger jeans as their number one brand in a survey in 2000.52. What is the best title for this passage?(A) The Importance of Marketing (B) The Power of Youth Culture(C) The Popularity of Hip-hop Fashion (D) The Success of Tommy Hilfiger53. How much money do sales of rap music and videos together make each year?(A) More than $1 billion. (B) Between $750 million and $1 billion.(C) Between $500 million and $750 million.

It probably originated in the vicinity of China. There were guitars in ancient Egypt and Greece as well, but the written history of the guitar starts in Spain in the 13th century. By 1500 the guitar was popular in Italy, France, and Spain. A French document of that time concludes that many people were playing the guitar. Stradivarius, the undeniable king of violin makers, could not resist creating a variety of guitars. Also, there was no lack of music written for the instrument. Haydn, Schubert, and others wrote guitar music. When the great Beethoven was asked to compose music for the guitar, he went into a rage and refused, but eventually even Beethoven could not ignore the challenge. Legend tells us he finally called the guitar a miniature orchestra. Indeed the guitar does sound like a little orchestra! Perhaps that is why in rural areas around the world the guitar has been a source of music for millions to enjoy.1. Where is the earliest written record of the guitar found?2. What musical instrument was Stradivarius most famous for making?3. What was Beethoven’s first reaction when he was asked to write music for the guitar?4. What was the challenge that Beethoven could not ignore?5. What does “millions” in the last line refer to?提示︰- 9 -92學年度第 10 頁英文考科共7 頁請以“Music Is An Important Part of Our Life”為題,說明音樂(例如古典音樂、流行歌曲、搖滾音樂等)在生活中的重要性,並以你或他人的經驗為例,敘述音樂所帶來的好處。
