「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.

She brought her characters to life in b witty stories with finely detailed watercolors. a Br herit The daughter of wealthy parents, Helen Beatrix Potter was born on July 28, 1866 in South Kensington, London. She was educated at home and developed a love of literature and art. She used to practice her craft bv making illustrations for fairy tales like Cinderella and Sleeping Beauty. Also drawn to nature, she and her younger brother Walter kept many pets mice, rabbits, even bats and a hedgehog and she loved her family's long holidays in the Scottish countryside and the Lake District, a mountainous area in northwest England. in 19 The As a child and teenager, Potter made great sketches of her pets, as well as of trees and plants. She also kept a diary in which she recorded her Qpinions about cultural and political ideas and events. She wrote in a secret bs nsgst Peri 1866- Code that was not broken until fifteen years after her death. In the 1890s, Potter began selling her drawings.Potter's work was used for Christmas and New Year cards and an illustration of poetry. She was pleased by this success and decided to publish her own illustrated stories for children. In 1901, after the manuscript. was rejected by several publishers, she self-published her first book, The Tale of Peter Rabbit, She had first written and drawn a version of the story in a letter to the. sick child of her former private teacher.、The child was so delighted with it that Potter felt other children would be, too. She was right. The story of naughty Peter, who always gets into trouble because he does not follow his sisters' example and obey his mother's rules, was very popular. 、In 1902, the publisher Frederick Warne & Company printed a commercial edition, and it went on to become one of the most famous children's books of all time 1 Over the next twenty years, Potter wrote and illustrated twenty-two more books with that publisher, her early_observations of the animals and plants of her childhood often making their way into the stories.
