20 Unit 1 - History - Gutenberg is famous for inventing printing, but he didn't really invent it. He invented a better way of printing. [2] For hundreds of years people used blocks of wood* to print. They used a knife to cut words backward in the block of wood. Then they covered the block with ink and pressed it onto paper. When they pulled the paper from the inky blocks, the words appeared on the 金属 5 paper in the right direction. In Korea and China, people printed with metal type* instead of 右向き wood. (2)Either way, printing was difficult and very slow. It took several years to make one copy of a book. [3] Books were very expensive and rare. Only ( 3a ) people could buy them, and ( 3b ) 10 people could not read. But, as ( 3c -) people learned to read, books became more popular. So people wanted to find a quicker, better and less expensive way to print books. One of these people was Johannes Gutenberg. opsugas.l Y tinU 9003 iinil 4 Gutenberg was born in Mainz, Germany, around 1400. He was good at working with metal, but probably had no idea how people printed in China. His idea was to make a piece Clarey operan 15 of metal type for each letter of the alphabet and use the letters (4)over and over. (5)He could put the type together to make words and arrange words to make pages. With ink on the type, he could press paper on them to print a page. A "printing press" machine could make hundreds of copies of a single page quickly. After that page, he could rearrange the same letters to make other words and print other pages. LISSH Si nou 5 It took Gutenberg a long time to make the type for each letter of the alphabet. When he finished the type, he didn't have enough money to make the printing press. He borrowed money from a man named Johann Fust. After many years, Gutenberg's printing press was Legione ready. Gutenberg printed his first book, the Bible, around 1455. 6 There are only twenty-one complete copies of the original Bible. They are some of the 25 most expensive books in the world. In 1987, part of a Gutenberg Bible sold for $5.3 million. 7 Today people remember Johannes Gutenberg. The city of Mainz has a statue of him and a museum. His original printing press is in the museum.

「I|次の文を読んで、あとの問いに答えなさい。( wのついた語は文末に注があります。 ns Sitting in the consultation room of a charming cosmetic surgery clinic in Washmgo. D.C., Hudson Young removed his mask under the satisfied gaze of his doctor. Like a grownns number of Americans, Young decided the right time to undergo plastic surgery was middle of a coronavirus pandemic, He knew he would have time to recover in the privacy ot his own home. The main reason, however, was that Young suddenly found himself face to face with his own image while participating in an increasing number of videophone and web A 「Its something new when you have to stare at your face for a couple of hours a day and there's only so much you can do with good lighting and good angles," Young said. The 52-year-old real estate agent had allready been a fan of cosmetic surgery. He had face lift, eyelid surgery and laser resurfacing for the first time in October. "When you see yourself on Zoom, you are shocked," he explained, as Dr. Michael Somenek examined his w barely visible scars. Young is far from the only one who has found himself disappointed with the reflection he has seen in the screen over the past year. Virtual consultations for cosmetic procedures have risen 64% in the United States since the beginning of the COVID-19 pandemic, according to the American Society of Plastic Surgeons. “We have seen an increase in the number of surgical cosmetic procedures that are directly related to Zoom," said Somenek, who has seen a 50% to 60% increase in customers. “I think the pandemic B has given everyone time to take care of those things that we've been putting off until later," explained Ana Caceres, who was able to work from home after C a plastic surgery operation she had wanted for a long time. She recovered at. her parents' house outside Washington after a December cosmetic surgery that helped her D deal with a source of insecurity she had had since adolescence. "I didn't have to days off, because I was still able to work from my bed with my lap-top," the 25-year-old said. “When life is going on and you have places to be, it's s0 easy to put things off," Caceres said, showing off a dress she says she now has the confidence to wear. And she has scheduled more cosmetic surgery. Her surgeon, Dr. Catherine Hannan, says consultations at her clinic in the IIS comit1 E have nearly doubled since the beginning of the pandemic. "Our patients have more lines because the last vear has been so hard. A face or boay change can have a psychological
