2021年河南省实验文博学校高三英语月考试题及答案

2021年河南省实验文博学校高三英语月考试题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ASome young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.1. What can we learn about the 3M Young Scientist Challenge in 2018?A. It was intended to solve medical problems.B. It was a nationwide AI competition for teenagers.C. It offered the finalists an opportunity to work with scientists.D. It allowed the finalists to learn AI technology in the 3M center.2. How did Rishab win the 3M Young Scientist Challenge?A.He showed excellent programming ability.B. He figured out the survival rate of pancreatic cancer.C. He introduced poor children to STEM education.D. He applied AI technology to treating pancreatic cancer.3. Which of the following best describes Rishab?A. Talented and caring.B. Independent and humorous.C. Responsible and patient.D. Polite and inspiring.BJoy Mangano is now an American inventor. She was divorced and had three kids under age 7 when she was 33, and was barely keeping up payments on her small two-bedroom home by working extra hours as a waitress. “There were times when I would lie in bed and think. I didn't know how I was going to pay that bill,” Mangano says.But she had a special ability for seeing the obvious thing. She knew how hard it was to mop the floor. “I was tired, of bending down, putting my hands in dirty water, wringing (拧) out a mop,” Mangano says. “So, There's gotta be a better way.”How about a “self-wringing” mop? She designed a special tool you could twist in two directions at once, and still keep your hands clean and dry. She set out to sell it, first a few at flea markets.Then Mangano met with the media. But would couch potatoes (电视迷) buy a mop? The experts on shopping TV were less than certain. They gave it a try, and it failed Mangano was sure it would sell if they'd let her do the on-camera display. She said, “Get me on that stage, and I will sell this mop because it's a great item.”So QVC, a multinational corporation specializing in televised home shopping, took a chance on her. “I got onstage and the phones went crazy. We sold every mop in minutes.”Today she's president of Ingenious Designs, a multimillion-dollar company, and one of the stars of HSN, the Home Shopping Network. Talking about the household invention, Mangano says, “It is as natural for me as it is fora parent to talk about their child.”4. What is the first paragraph mainly about?A. Mangano's small home.B. Mangano's work experience.C. Mangano's unhappy marriage.D. Mangano's hard living conditions.5. Mangano sold the mop successfully with the help of ________.A. HSNB. QVCC. couch potatoesD. experts on shopping TV6. What does Mangano think of her invention?A. Normal.B. Special.C. Unsatisfactory.D. Unbelievable.7. What can we learn from the text?A. HSN is a business organization that sells goods on the Internet.B. The experts on shopping TV were confident about Mangano's mop.C. Mangano got the idea of self-wringing mop from her own experience.D Mangano once had to work seven days a week to support her family.CWhen an animal species is considered endangered, it means that the International Union for Conservation of Nature (IUCN) has evaluatedit as nearly extinct, which means that a majority of its population has already died off and the rate of birth is lower than the species’death rate. Today, more and more animal and plant species are on the way to extinction because of a variety of major factors that cause a species to become endangered, and as you might expect, humans play a role in quite a few of them — in fact, the biggest threat to endangered animals is human encroachment (侵入) on their habitats.Every species needs a habitat, where an animal finds food, raises its young. Unfortunately, humans destroy animal habitats in a number of different ways: building houses, clearing forests to getlumberand to plant crops, draining rivers to bring water to those crops, and making streets and parking lots.In addition, human development pollutes the environment with all kinds of chemicals, which destroys food sources and shelters for the creatures and plants of that area. As a result, some species die out while others are pushed into areas where they can’t find food and shelters — to make matters worse, when one animal population suffers, it affects many other species in its food web, so more than one species’population is likely to decrease.Habitat destruction is the number one reason for animal endangerment, which is why conservation groups work hard to repair the effects of human developments — many non-profit groups like the Nature Conservancy are taking measures to clean up coastlines and establish nature preserves to prevent further harm to native environments and species around the world.8. A species is considered endangered________.A. when the IUCN has noticed its population changeB. when most of its population has died offC. when the species’ birth rate is close to its death rateD. when the species is losing its habitat9. What does the underlined word “lumber” probably mean?A. Gas.B. Food.C. Chemicals.D. Wood.10. What is being done to protect the endangered species?A. Calling for human development.B. Raising money.C. Establishing nature preserves.D. Educating people.11. What is the main idea of the passage?A. Habitat destruction causes animal endangerment.B. Animals die out due to environment pollution.C. Measures need to be taken to increase species.D. Non-profit groups are making great contributions.DWhen the COVID-19 hit and supermarket shelves were empty, Chris Hall and Stefanny Lowey decided they no longer wanted to rely on others for food. The couple, who live on Pender Island in BritishColumbia, Canada, decided to start a year-long challenge where they wouldn't buy a single thing to eat. Instead they would grow, raise or catch everything—right down to sugar, salt and flour. Now, five months in, they say the challenge has changed their lives.Chris, 38, said, “It has always been something that we have wanted to do. We have had a garden and grown vegetables for a long time already. When the COVID-19 hit, it gave us that extra push that we needed to do it. We were both out of work when we started, and with the reality check of grocery stores running out of items, it gave us even more motivation to see if we could look after ourselves.”The pair spent the months before building a house for chickens, ducks and turkey as well as studying as much as possible to figure out where they would get all the things they needed. Chris adds, “We had to learn so many new things like how to grow mushrooms, process our Stevia plants, and harvest salt from the ocean. We spent a lot of time reading and studying online to figure out all the things we were going to need to do.”Now after five months, they both feel its been going well but Chris admits the first few weeks were difficult. “The first three weeks were very challenging as our bodies adjusted to cutting out coffee, wine and sugar all on the same day,” he says. “After three weeks our energy levels balanced out and our wishes reduced and now we feel great.” Now February has ended. As they come through winter, they feel positive about continuing with this way of living, with their challenge officially ending in August.12. Why did the pair decide to produce foods on their own?A. They were isolated by Pender Island.B. They couldn't afford to buy them because they were out of work.C. They believed it's good for their health.D. They could hardly buy them in shops.13. Which words can be used to describe the couple?A. Rich and generous.B. Helpful and positive.C. Optimistic and self-dependent.D. Motivated and brave.14. What can we learn from the last paragraph?A. Their challenge may last about eleven months in total.B. They were discouraged by the difficulty at first.C. They had difficulty because they wanted more.D. They couldn't adjust their bodies to the hard work after three weeks.15. In which column may you read such a passage?A. Sports.B. Agriculture.C. Lifestyle.D. Business.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。
