2019-2020学年重庆第二外国语学校高三英语二模试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AGetting your kid to bed at night is seriously one of the most challenging things you'll ever have to do. Most kids are just so full of energy that they'll tire you out before they're halfway through their store of energy. An easy thing to calm down your child to get into bed is giving in and allowing some iPad screen time. However, it's really not a great idea, just like you thought.Researchers at theArizonaStateUniversityconducted a study with 547 kids between the ages of 7 to 9. Their parents tracked how much screen time the kids were allowed along with their sleep patterns. The study found that kids who did not engage in screen time before bed slept for 23 more minutes every week and also went to sleep about 34 minutes earlier than those playing with iPad. Although that might not seem like so much more time, quality of sleep is vastly important in Children's development.The CDC's (美国疾病控制中心)2018 National Youth Risk Survey outlines that good quality sleep can impact a child's life in many ways, including affecting grades and also weight gain. Students with an "A" average slept for 30 or more minutes per night than those with a "D" or"F" average.A 2018PennsylvaniaStateUniversitystudy showed that children with irregular bedtimes had a higher risk of having increased body weight. Those with consistent and age-appropriate bedtimes when they were 9 years old had a healthier BMI (体质指数)at age 15 than those with irregular bedtimes.Hard as it is, it's really important not to give in and hand over an iPad to your child who is about to go to bed. Just like it's important for adults to go to sleep without any distractions, it's even more important for kids.1. What do the findings of the researchers at theArizonaStateUniversitysuggest?A. More sleep is necessary for children's development.B. Enough sleep helps improve academic performances.C. Screen time before bed leads to later and less sleep.D. Children sleeping irregularly are easy to gain weight.2. What is the text mainly about?A. How is screen time affecting teenagers?B. What are negative effects of irregular bedtimes?C. When should you get your kid to bed at night?D. Why is screen time before bed a bad idea for kids?3. Who is the text intended for?A. Parents.B. Children.C. Teachers.D. Researchers.BFor years, Zach Ault, a father of three, enjoyed being physically active. He was even training for a half-marathon. But in 2017, he took time off to recover from an infection. After recovering, he tried to continue his runs but could not complete them. He was not able to spend time with his children. He had to cut back his job. Even sleeping as much as 16 hours a day made no difference in his condition.“His body had literally hijacked him and it wasn't going to allow him to push through, ” said Anne Ault, his wife. After months of testing, doctors announced their result-chronic fatigue syndrome, a disease that makes an individual feel extremely tired.This fatigue lasts more than six months and becomes worse after any kind of physical exertion (费力活动). Patients may have difficulty standing upright. They also may have trouble thinking, often described as a “brain fog”. There are no approvedtreatments, or even tests to help with diagnosis. There is no way to predict who will recover and who will have a severe case that lasts for years.Now the doctors at the National Institutes of Health (NIH) are conducting a unique study to learn more about the condition. Zach Ault is one of the subjects in the study. When Ault rides an exercise bicycle, scientists measure how his leg muscles use oxygen. Afterward, doctors fit a special cap on Ault's head to measure electrical activity in his brain. They then send him to spend the night in an air-tight room where air has been removed with pipe for additional study. Scientists measure oxygen and carbon dioxide levels to tell how much energy Ault is using, minute by minute. “We're figuring out how his body adjusts to an exercise load, or a stress load.”“It's hard not knowing if or when I'm going to recover, ” he said. But Ault says the study did help him learn about the disease. And it gave him ideas about how to save up his energy.4. What was Zach Ault's life like before 2017?A. He was fond of exercising.B. He won several half-marathons.C. He spent much time lying in bed.D. He was busy looking after his children.5. How did the infection affect Zach Ault?A. He lost his job.B. He was unable to sleep.C. He became too weak to do sports.D. He was tired of running a half-marathon.6. What can we learn about chronic fatigue syndrome?A. It usually lasts no more than months.B. It is likely to cause thinking disorders.C. Patients with it need to stay in bed all day long.D. Patients with it should avoid any kind of exercise.7. What does Zach Ault think of the study?A. It helped him cure his illness.B. It helped him recover and stay fit.C. It taught him how to enjoy cycling.D. It brought him new ideas about fighting diseases.CMark Bertram, 46, lost the tips of two fingers at work in 2018 when his hand became trapped in a fan belt. “It's life-changing but it's not life-ending,” he says. “Doing work is harder now. Everything is just a little different.”After two surgeries and occupational therapy, Bertram decided to make light of his condition by asking Eric Catalano, a tattoo (纹身) artist, to create fingernail tattoos. The idea made everyone in the studio laugh—until they saw the final result. “The mood changed,” Catalano recalls from his Eternal Ink Tattoo Studio. “Everything turned from funny to wow.”When Catalano posted a photo of the tattoos, a pair of fingernails that looked so real that no one could believe their eyes, he had no idea the image would eventually be viewed by millions of people around the world.The viral photo pushed Catalano, 40, further into the world of paramedical (辅助医疗的) tattooing. Now people with life-altering scars come from as far away as Ireland to visit his shop. They enter Eternal Ink looking for the artistic healing they saw online. Using flesh-toned (肉色的) inks and a needle, Catalano transforms his clients' view of themselves.Leslie Pollan, 32, a dog breeder in Oxford, was bitten on the face by a puppy in 2014. She underwent countless surgeries to correct a scar on her lip.“Plastic surgery gave me no hope,” she says. “So I looked for other options.” She ultimately traveled six hours to meet with Catalano. He hid Pollan's lip scar, giving her back a piece of her confidence.“ You don't understand until you've been through it,” Pollan says. “It made me have a different look on life.”Catalano performs up to eight reconstructive tattoos. While he charges $100 per regular tattoo, he doesn't charge for paramedical tattoos. “Financially, it doesn't make sense,” Catalano says. “But every time I see that emotion from my customers, I'm 100 percent sure this is something that I can't stop doing.”8. What best describes people's attitude when first hearing of fingernail tattoos?A. Indifferent.B. Ridiculous.C. Confident.D. Surprised.9. What did Catalano do to help Leslie Pollan?A. He drew an artistic puppy.B. He inked scars on her face.C. He created a lip tattoo.D. He performed plastic surgeries on her.10. What can we infer from the passage?A. Cosmetic surgery is of no use.B. Tattoos earn Mark Bertram a good fame.C. Catalano is a kind and generous person.D. Fingernail tattoos are popular around the world.11. What could be the best title for the text?A. A Life-changing EventB. Miracle TattoosC. An Amazing ArtistD. A Promising BusinessDThe year 2020 will mark the beginning of the decade of the yold, or the “young old”, as the Japanese call people aged between 65 and 75. The traditional retirement age is 65. One might therefore expect peak retirement. By continuing to work, and staying socially engaged, the yold will change the world, as they have done several times before at different stages of their lives.The yold are more numerous, healthier and wealthier than previous generations of seniors. The yold are busier, too. In short, the yold are not just any group of old people. They are challenging the traditional expectations of the retired as people who wear slippers and look after the grandchildren. That will influence consumer, service and financial markets.The over-60s are one of the fastest-growing groups of customers of the airline business. The yold are vital to the tourism industry because they spend much more, when taking a foreign holiday, than younger adults.But for all this to happen,three big things will have to change, under pressure from the yold themselves. The most important is public attitudes towards older people, and in particular the expectation that the old ought to be putting their feet up and quietly retiring into the background. Then, government policies will have to change, too.The retirement age in many rich countries is still below the age to which many people want to work. The effective retirement age (the age at which people actually leave the workforce) is usually even lower. Third, higher numbers of healthy yold people will require drastic changes in health spending. Most diseases of ageing are bestmetwith prevention and lifestyle changes. But only about 2%~3% of most countries’ health-care spending goes on prevention. That will have to rise, because although the yold will constitute a bulge of comparative health and activity over the next decade, by 2030 they will hit 75 and enter a long period of decline for which few rich countries are ready.12. What kind of people are the yold exactly?A. They are workaholics.B. They are full of energy.C. They enjoy being focused on.D. They like staying socially engaged.13. Why do the yold contribute to tourist industry?A. They like traveling more.B. They have more money.C. They consume more on travel.D. They have much free time.14. What’s the author’s attitude toward health-care spending on prevention?A. Unsatisfied.B. Subjective.C. Neutral.D. Active.15. What does the underlined word “met” in the fourth paragraph mean?A. dealt withB. come acrossC. satisfiedD. experienced.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
