Three men, working in three different areas of the world, made this possible. (1) The first man who collected a large number of fingerprints was William Herschel. He worked for the British government in India. He took fingerprints when people (7) official papers. For many years, he collected the same people's fingerprints several times. He made an important discovery. Fingerprints do not change over time. At about the same time, a Scottish doctor in Japan began to study fingerprints. Henry Faulds was looking at ancient Japanese pottery* one day when he noticed small It occurred to him that the lines were 2,000-year-old fingerprints. Faulds wondered, "Are fingerprints unique to each person?" He began to take fingerprints of all his friends, co-workers, and students at his medical school. Each print was (). He also wondered, "Can you change your fingerprints?” shaved the fingerprints off his fingers with a razor to find out. Would they grow back lines on the pots. (2) He the same? They did. One day, there was a theft in Faulds's medical school. Some alcohol was missing. Faulds found fingerprints on the bottle. He compared the fingerprints to the ones in his records, and he found a match. The thief was one of his medical students. By examining fingerprints, Faulds solved the crime. Both Herschel and Faulds collected fingerprints, but there was a problem. It was very difficult to use their collections to identify a specific fingerprint. Francis Galton in England made it easier. He noticed common patterns in fingerprints. He used these to help classify fingerprints. These features, called "Galton details," made it easier for police to search through fingerprint records. The system is still in use today. When 25 police find a fingerprint, they look at the Galton details. Then they search for other fingerprints with similar features. (4) Like Faulds, Galton believed that each person had a unique fingerprint. According to Galton, the chance of two people with the same fingerprint was 1 in 64 billion. Even the fingerprints of identical twins are ( ). Fingerprints were the perfect tool to 30 identify criminals. For mo than 100 years, no one found two people with the same prints.

However, ( 7 ) Mozart produced in his early years is not considered to be particularly outstanding. He didn't produce his first true masterpiece* until he was 21; pretty s young to be sure, but Mozart ( 1 ) already been composing for years by this time. 10 The figure of 10,000 hours has been suggested as the amount (1 of serious practice or study needed to truly master a skill. That is nearly two hours a day, every day, for 14 years. Natural ability is, of course, an important factor in success, but even someone as talented as Mozart couldn't become a "great" composer until he had put in* 10,000 hours of hard work. The same can be said of golfer Tiger Woods and computer genius Bill Gates. Most people in developed countries can expect to have a healthy life of at least 70 years, or 613,608 hours. Although that seems like a ot of hours, most people spend about a third of them asleep.

中間 UNIT 7 Reading V かず 忌み数(縁起の悪い数字) を意識して行動することがありますか。 テーマ 思想・哲学・宗教 Which number sounds lucky or unlucky to you? In many cultures around the world, people believe that some numbers are unluckier than others. In most Western cultures, many people consider the number 13 to be unlucky. In the United States, for example, many cities do not have a 13th street; many buildings 5 do not have a 13th floor. You might have seen the 13th floor (Ⓒ) as 14 in the elevator. ~412 つまり - - one on There are also those who believe that Friday the 13th is an unlucky day - 〜の人は which many things can go wrong. *superstition 文法項目 分詞①(補語になる分詞) Track 35-36 ②. The exact origin of *superstitions about Friday the 13th remains unknown. 10 However, superstitious fears about this date have grown and spread over the years, thanks, in part, to unfortunate events. In the 19th century, a ship — the HMS Friday - which was launched on a Friday the 13th, disappeared at sea. On a Friday the 13th in 1992, an earthquake in *Turkey killed thousands of people. Note It is surprising, though, that the number 13 is considered unlucky in the United 15 States. The country was originally divided into 13 states. On the dollar bill there is a picture of an *incomplete *pyramid with 13 steps. The *bald eagle carries an *olive branch in one of its *claws with 13 leaves and 13 *berries on it. In the other claw it is holding 13 arrows, and above its head there are 13 stars. In different cultures, other numbers are believed to be unlucky. In Japan, Korea, 20 and China, for example, people consider the number four to be unlucky because the *pronunciation of the word meaning four is very similar to the pronunciation of the word that means death. Many hotels and hospitals in these countries do not have a room number four. Also, people ( 4 ) give a gift consisting of four items. Turkey トルコ Noto (302 words)
