次の英文を読んで, 設問に答えなさい。 [5] The headline grabs your attention: "The ancient tool used in Japan to boost memory." You've been The Japanese art of racking up clicks online more forgetful recently, and maybe this mysterious instrument from the other side of the world, no less! could help out? You click the link, and hit play on the video, awaiting this information that's bound to change your life. The answer? A soroban (abacus). Hmm, () それは私がどこに鍵を置いたか覚えておく助けになりそうには ないですよね? This BBC creation is part of a series called "Japan 2020," a set of Japan-centric content looking at various inoffensive topics, from the history of Hiroshima-style okonomiyaki pancakes to pearl divers. The abacus entry, along with a video titled "Japan's ancient philosophy that helps us accept our flaws," about kintsugi (a technique that involves repairing ceramics with gold-or silver-dusted lacquer), cross over into a popular style of exploring the country: Welcome to the Japan that can fix you. For the bulk of the internet's existence, Western online focus toward the nation has been of the "weird Japan" variety, which zeroes in rare happenings and micro "trends," but presents them as part of everyday life, usually just to entertain. This sometimes veers into "get a load of this country" posturing to get more views online. It's not exclusive to the web traditional media indulges, too but it proliferates online. Bagel heads, used underwear vending machines, rent-a-family services - it's a tired form of reporting that has been heavily criticized in recent times, though that doesn't stop articles and YouTube videos from diving into "weird Japan." These days, wacky topics have given way to celebrations of the seemingly boring. This started with the global popularity of Marie Kondo's KonMari Method of organizing in the early 2010s, which inspired books and TV shows. It's online where content attempts to fill a never-ending pit - where breakdowns of, advice and opinions about Kondo emerged the most. Then came other Japanese ways to change your life. CNBC contributor Sarah Harvey tried kakeibo, described in the headline as "the Japanese art of saving money." This "art" is actually just writing things down in a notebook. Ikigai is a popular go-to, with articles and videos popping up all the time explaining the mysterious concept of ... having a purpose in life. This isn't a totally new development in history, as Japanese concepts such as wa and wabi sabi have long earned attention from places like the United States, sometimes from a place of pure curiosity and sometimes as pre-internet "life hacks" aimed making one's existence a little better. (B) The web just made these inescapable. There's certainly an element of exoticization in Western writers treating hum-drum activities secrets from Asia. There are also plenty of Japanese people helping to spread these ideas, albeit mostly in the form of books like Ken Mogi's "The Little Book of Ikigai." It can result in dissonance. Naoko Takei Moore promotes the use of donabe, a type of cooking pot, and was interviewed by The New York Times for a small feature this past March about the tool. Non- Japanese Twitter users, in a sign of growing negative reactions to the "X, the Japanese art of Y" presentations, attacked the piece... or at least the headline, as it seemed few dove the actual content of the article (shocking!), which is a quick and pleasant profile of Takei Moore, a woman celebrating her country's culinary culture. Still, despite the criticism by online readers, the piece says way more about what English-language readers want in their own lives than anything about modern Japan. That's common in all of this content, and points to a greater desire for change, whether via a new cooking tool or a "Japanese technique to overcome laziness." The Japan part is just flashy branding, going to a country that 84% of Americans view positively find attention-grabbing ideas for a never-ending stream of online content. And what do readers want? Self-help. Wherever they can get it. Telling them to slow down and look inside isn't nearly as catchy as offering them magical solutions from ancient Japan.

Reading 00000000000000 Read the passage and answer the questions. The number of foreign tourists to Japan is increasing every 60 year. In 2016, over 20 million people visited Japan for sightseeing. Many of the visitors come from Asian countries near Japan. These tourists enjoy Japan's unique food, traditional buildings, 5 and natural scenery. But the Japanese government wants even more tourists to come. They started a plan to encourage tourists to visit the country more than once. First, the government asked tourists what they want to do during their first visit. Eating Japanese food is the most popular 10 activity. The least popular is skiing. Next, they asked them what they want to do on a second visit. The research shows that few tourists want to do the same activities again, such as eating Japanese food. However, skiing and snowboarding, and nature tours are more attractive for second time visitors than first- 15 timers. The biggest increase is in seasonal experiences, such as seeing cherry blossoms in the spring or falling leaves in the autumn. Clearly, foreign tourists want to experience something new and unique for their second visit.

35 15 20 signatures in business. However, no one used fingerprints in crime work until the late In ancient times, people used fingerprints to identify people. They also used them as 1880s. 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.
