2019高考英语一轮复习练习题Unit3Underthesea(含解析)新人教版选修7

Under the sea李仕才一、阅读理解When I was in the sixth grade, I became a big K-pop (Korean pop) fan. Almost half the students at my middle school were Korean and almost all of them listened to Korean music, especially K-pop. I had never been interested in it. It sounded too strange to me, but all changed in the sixth grade when the huge hit Gee came out. All my friends were singing the chorus and imitating the dance. Gee fever sucked me into K-pop. It became my life. I listened to K-pop non-stop and filled my iPod with it. In a month, I had memorized the names of countless members of boy and girl bands and stuck pictures of my singer "boyfriends" on my walls. I would ditch my weekend art and math classes and go to concerts with my friends. This would always result in my mom shouting that I was wasting my life. My mom thought K-pop was trash and wanted me to like classical music as she did. But classical music made me sleepy.Every day during middle school I went to a K-pop gossip and news site called . On this site I learned that I could audition(试音) to become a singer in a K-pop band. The shining clothes, thousands of screaming fans and hearing them chant my name seemed much more exciting than being a middle school student. Becoming a K-pop star was all I wanted.I started watching the audition videos of current stars and reading blog posts from people who had auditioned. They explained much about the audition. This made me want to audition even more. After watching those videos, I saw that most of the current stars weren’t that amazing in their auditions and that each singer had improved so much through training. I had never had vocal lessons(声乐课) and didn’t think of myself as a good singer. "But if they could do it, I could do that too," I thought.1.What caused the author to fall in love with K-pop?A. Her Korean origin.B.A new style of dance.C. Her friends’ influence.D. The popularity of Gee.2.The underlined word "ditch" in Paragraph 1 probably means "________".A. forgetB. attendC. ignoreD. hate3.What do we know about the author’s mother?A. She has no interest in music.B. She has a low opinion of K-pop.C. She doesn’t care about her daughter.D. She prefers K-pop to classical music.4.After visiting , the author ________.A. dreamed of becoming a pop singerB. called the manager of the news siteC. contacted people who had auditionedD. knew she would never become a singer【文章大意】本文是一篇记叙文。

Passage 1I've spent over a year in India, and in those 365 plus days, I've learned a lot about getting around Indian cities. My biggest lessons have been learned through being cheated, particularly by taxi and rickshaw (人力车) drivers, but that doesn't mean those are bad ways to travel, as long as you know what you're doing. Below are the best ways to get around the city of Delhi, India, and tips for how to keep from being the victim of scams (欺诈).Taking taxis is a great way to get around the city of Delhi and chances are, if you arrive in Delhi by plane, as soon as you make it through customs, you'll be swarmed by Indian taxi drivers. At the Delhi airport, be sure to arrange for a taxi to your hotel at one of the two Delhi Traffic Police Taxi Booths. One is inside theairport, and the other is outside. The key is to make sure to go to a booth run by the police, rather than by independent taxi drivers.Rickshaws are one of my favourite ways to get around Indian cities, in part because it's how the locals often travel. Auto-rickshaws are more common, but bicycle rickshaws are still used in Old Delhi. If you do have a chance to take a bicycle rickshaw, you should do it at least once for a unique experience that should only set you back about 15 rupees. Auto-rickshaw rates around Delhi range between 30 and 80 rupees, depending on the distance.If you really want to travel around Delhi like the locals, take a public bus. Indian buses become very crowded and most do not have air conditioning. They are, however, very cheap. A bus trip won't set you back any more than 15 rupees, as long as you stay within the city limits. Since Indian buses get so crowded, try to board the bus at the start of the route so you can get a seat.The train is a great way to get around within the city of Delhi. Fares are reasonable, between 6 and 22 rupees. All departure announcements are in both Hindi and English, and tokens can be purchased for between 6 and 22 rupees.【语篇解读】本文作者就自己在印度德里旅行时的交通方面提出了几点建议。

Unit 3 The Million Pound Bank Note李仕才一、阅读理解。
Career criminals begin their antisocial behavior during their toddler (学步的儿童) years and may go on with a life of crime if their behavior isn’t challenged, scientists have discovered. While most children grow out of their bad behavior by adulthood, a study found those who had “callous unemotional (冷漠无情的) characteristics” could grow up to have problems with the law later in life. Behavior characteristics such as a lack of sympathy and lying in childhood could have an impact years on.Luke Hyde, assistant professor of psychology at the University of Michigan, said, “These are signs for parents and doctors to watch out for, as they may signal more than just the terrible twos.” He said, “Parents both take care of the ir child and provide their child’s genes so it’s been difficult to know if we’re seeing that parenting causes callous unemotional behaviors, or if it is just a sign of the genes being passed to the child.”The research also discovered that strict parenting is linked to the development of antisocial behavior. Scientists looked at 561 families in an adoption study that examined biological mothers’ antisocial behavior. The scientists found children of antisocial mothers were also more likely to exhibit the same behavior characteristics, despite having limited or no touch with them as they were adopted as babies.“The really exciting take-home message from this study is that small, day-to-day positive interactions (互动) that parents have with their young children can make a huge difference in children’s development,’’ said Leslie Leve, a professor at the University of Oregon who co-led the data collection.“Even when children have inherited (遗传) a very challenging set of behaviors, hearing ‘good job’ or receiving encouragement can help protect them from developing serious problems coming from their inherited difficul ties,” he added. The study, worked on by scientists from the University of Michigan, Penn State University and theUniversity of Oregon has been published in the American Journal of Psychiatry. Researchers will follow the group of children through early adolescence to determine if these behaviors still continue to exist from the toddler years.1.What’s the main idea of the passage?A. Kids’ social behaviors are related to crime.B. Criminals begin their crimes during adolescence.C. Antisocial behaviors of kids could be on their way to a life of crime.D. Warmhearted kids are more likely to be criminals in the future.2.What conclusion might the scientists draw from the study?A. Antisocial behaviors might be inherited.B. The genes decide kids’ antisocial b ehaviors.C. Antisocial behaviors have nothing to do with crimes.D. Adopted babies surely have antisocial behaviors when they grow up.3.What can be inferred from the passage?A. Parenting is the main reason that causes kids’ antisocial behaviors.B. What causes career criminals to begin their crimes is their parents’ characteristics.C. Leslie Leve has a doubtful attitude to adoptive mothers’ active interactions with kids.D. Inherited antisocial behaviors of kids can be lightened by positive parenting.4.Why will researchers track kids’ process of growing?A. To make sure if kids’ behaviors will last.B. To make sure if praise will change kids.C. To determine if kids’ behaviors will be inherited.D. To determine if parents’ comfort will protect kids.【文章大意】研究人员发现孩子的反社会行为有可能使他们走向犯罪的道路,积极的育儿方式可以减轻孩子的反社会行为。

专题三推理判断题Passage 1[2017甲卷(全国Ⅱ),D]When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbors react.Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.In study after study, it appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to "overhear" the cry. So information was exchanged, but it wasn’t a true, intentional back and forth.Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.32.What does a plant do when it is under attack?A. It makes noises.B. It gets help from other plants.C. It stands quietly.D. It sends out certain chemicals.33.What does the author mean by "the tables are turned" in paragraph 3?A. The attackers get attacked.B. The insects gather under the table.C. The plants get ready to fight back.D. The perfumes attract natural enemies.34.Scientists find from their studies that plants can .A. predict natural disastersB. protect themselves against insectsC. talk to one another intentionallyD. help their neighbors when necessary35.What can we infer from the last paragraph?A. The world is changing faster than ever.B. People have stronger senses than before.C. The world is more complex than it seems.D. People in Darwin’s time were more imaginative.Passage 2[2017浙江,B]Getting less sleep has become a bad habit for most American kids. According to a new survey(调查)by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest; most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV."More children are going to bed with TVs on, and there are more opportunities(机会)to stay awake, with more homework, the Internet and the phone," says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.25.What is the new National Sleep Foundation survey on?A. American kids’ sleeping habits.B. Teenagers’ sleep-related diseases.C. Activities to prevent sleeplessness.D. Learning problems and lack of sleep.26.How many hours of sleep do 11-year-olds need every day?A. 7 hours.B. 8 hours.C. 10 hours.D. 18 hours.27.Why do teenagers go to sleep late according to Carskadon?A. They are affected by certain body chemicals.B. They tend to do things that excite them.C. They follow their parents’ examples.D. They don’t need to go to school early.Passage 3[2016北京,B]Surviving Hurricane Sandy(飓风桑迪)Natalie Doan, 14, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach. Natalie can see the ocean and hear the waves from her house. "It’s the ocean that makes Rockaway so special," she says.On October 29, 2012, that ocean turned fierce. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie’s family escaped to Brooklyn shortly before the city’s bridges closed.When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie’s friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie’s school was so damaged that she had to temporarily attend a school in Brooklyn.In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings."My mom tells me that I can’t control what happens to me," Natalie says, "but I can always choose how I deal with it."Natalie’s choice was to help.She created a website page, matching survivors in need with donors who wanted to help. Natalie posted information about a boy named Patrick, who lost his baseball card collection when his house burned down. Within days, Patrick’s collection was replaced.In the coming months, her website page helped lots of kids: Christopher, who received a new basketball; Charlie, who got a new keyboard. Natalie also worked with other organizations to bring much-needed supplies to Rockaway. Her efforts made her a famous person. Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.Today, the scars(创痕) of destruction are still seen in Rockaway, but hope is in the air. The streets are clear, and many homes have been rebuilt. "I can’t imagine living anywhere but Rockaway," Natalie declares. "My neighborhood will be back, even stronger than before."59.When Natalie returned to Rockaway after the hurricane, she found .A.some friends had lost their livesB.her neighborhood was destroyedC.her school had moved to BrooklynD.the elderly were free from suffering60. According to Paragraph 4, who inspired Natalie most?A.The people helping Rockaway rebuild.B.The people trapped in high-rise buildings.C.The volunteers donating money to survivors.D.Local teenagers bringing clothing to elderly people.61.How did Natalie help the survivors?A.She gave her toys to other kids.B.She took care of younger children.C.She called on the White House to help.D.She built an information sharing platform.62.What does the story intend to tell us?A.Little people can make a big difference.B.A friend in need is a friend indeed.C.East or west, home is best.D.Technology is power.Passage 4[2015四川,B]Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.And every week he cleaned Old Man McColgin’s chicken house in exchange for manure (肥料). The smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops,and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew (炖菜). Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour, the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad’s pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!Determined, Dad filled our plates with steaming stew and passed them around. It didn’t look that bad, and after the first wave had shut down my ability to smell, it didn’t offend the nose so much, either. I took a taste. It would never win a prize in a cooking competition, but it was surprisingly edible, and we drank up every last drop of soup!34.Why did Dad clean Old Man McColgin’s chicken house regularly?A.To earn some money for the family.B.To collect manure for his crops.C.To get rid of the terrible smell.D.To set a good example to us.35.What can we infer about Dad’s stew?A.It is popular among the neighbors.B.It contains honey and vegetables.C.It looks very wonderful.D.It tastes quite delicious.36.What does the underlined word "offend" in the last paragraph mean?A.To attract.B.To upset.C.To air.D.To shut.37.What can we learn about Dad from the text?A.He is an experienced cook.B.He is a troublesome father.C.He has a positive attitude to life.D.He suffers a lot from his disability.Passage 5[2014重庆,C]The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid — we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we’d need huge feet that we could bring up to our ears in order to create adequate "hitting".But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles (粒子) in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink — and take a shower afterward!44.Walking on water hasn’t become a reality mainly because humans .A.are not interested in itB.have biological limitationsC.have not invented proper toolsD.are afraid to make an attempt45.What do we know about Basilicus basilicus from the passage?A.It is light enough to walk on water.B.Its huge feet enable it to stay above water.C.It can run across water at a certain speed.D.Its unique skin keeps it from getting wet in water.46.What is the function of the cornflour according to the passage?A.To create a thick liquid.B.To turn the water into solid.C.To help the liquid behave normally.D.To enable the water to move rapidly.47.What is the author’s attitude toward the idea of humans’ walking on water?A.It is risky but beneficial.B.It is interesting and worth trying.C.It is crazy and cannot become a reality.D.It is impractical though theoretically possible.答案Passage 1本文是一篇说明文,介绍了植物在受到昆虫的攻击时是如何进行自我保护的,同时引出世界比我们人类想象的要复杂得多这一观点。
