tion adv. 驚人地 47 From Japan to the World 2022 apan's most famous traditional food, sushi, has satisfied people's appetites around the world. We usually think of sushi as bite sized slices of raw fish laid who eat sushi love it. The sushi we eat today, however, is quite different from that many are unable to accept the thought of eating uncooked pieces of fish. But those on rice. Eaten as a snack or main course, sushi is light and healthy. At first sight, of the past. Long before the invention of refrigerators, in Japan, freshly-caught fish was preserved in salt and put in rice to keep it edible for a longer time. This process gave the fish a strong and sour flavor, and also kept it from rotting. After it was preserved, people ate the fish without the rice.com me novell Later, as methods of maintaining food improved, rice vinegar replaced the preservation process. And instead of throwing away the rice, the Japanese began eating it with the fish. Since the preservation process was no longer needed, sushi became quick and easy to prepare and eat. IW BDE As sushi's popularity exploded in Tokys across Japan, and around the globe, 15 a Japanese man named Yoshiaki Shiraishi who had problems running a small sushi shop by himself, invented kaiten sushi, or conveyor belt sushi. His first kaiten sushi restaurant opened in 1958 in Osaka, Japan, and quickly caught on. 5 10 In kaiten sushi restaurants, plates of sushi move around on a conveyor belt, and customers take whatever 20 catches their eye. This type of restaurant also makes it easier for those who don't speak Japanese to fully enjoy sushi. Through constant improvement, Japan has spread sushi, its gift to the world, all over the place. 139. 25

想問這題的C C選項指的不應該是說 買賣NFT比想像中複雜 但文中所指NFT的買賣那麼複雜,那為什麼不是錯的勒

第 39 至 42 題為題組 As we progress further into the digital age, new terms and technologies seem to pop up everywhere. The latest of these is "NFTs" or non-fungible tokens. If something is fungible, it means that it is able to be replaced by an item of identical value, such as currency. Therefore, a non-fungible token cannot be interchanged; it is unique. NFTs are linked to the blockchain-the digital database that supports online cryptocurrencies like Bitcoin and Ethereum. Let's take a deeper look at NFTs and how people can buy, sell, and trade them. In simple terms, NFTs are one-of-a-kind digital works of art. They can take the form of GIFs, tweets, virtual trading cards, images of physical objects, and more. NFTs tend to attract investors who believe in the future of blockchain technology, and who are willing to spend top dollar to obtain a new form of digital currency. For example, Jack Dorsey's first tweet sold for $2.9 million, a video clip of a LeBron James slam dunk sold for over $200,000, and a decade-old "Nyan Cat" GIF sold for $600,000. Clearly, the NFT market is something to be taken seriously. So, the next question is: how does one participate in it? modi naging dato Basically any digital image can be purchased as an NFT.
