However, I quickly realized on my first day that so much of what I learnedwas so very wrong. There are many things that a Google search cannot show about Sweden.The first is fika. A fika is taking a break from whatever you are doing to enjoy a coffee with friends. Swedes value community highly so it makes sense that they would like to set aside time each day to reconnect with others. Fika is a great time to meet new people as well as catch up with friends.I grew up in the American South where everyone is very friendly. I found that little things like not being asked my life story at the coffee shop by the waiter upset me. However, Swedish people are not rude. Instead, they practice being logom, which means “just enough”.The winters can be very dark and cold, so the Swedish people do not take any sunny day for granted. Since the weather has been fine, I have found myself walking a lot around Stockholm. Often it is easiest to get from place to place by walking, which allows you to see so much of the city and enjoy the fresh air. Though it has been very tiring to get used to, it also has made me feel better about all of the kardemummabullar that I have been eating!I think it is important for students who want to study abroad to know that it is hard to move to countries no matter how “similar” you may think they may be. You have to jump in with both feet and be patient with yourself as well as others. As long as you keep an open mind and are willing to learn, you will have a great experience.4. What do we know about fika?A. It is a waste of time.B. It is a way to balance life and work.C. It is all about drinking coffee.D. It is a Swedish social tradition.5. What does the author think of Swedish people?A. They are friendly.B. They seem a bit cold.C. They appear really rude.D. They are interested in other's life.6. Why does the author like walking?A. It is fun and not very tiring.B. It is good exercise on cold days.C It allows her to enjoy sunny days. D. It gives her the chance to eat the local food.7. What's the author's advice for students going abroad?A. Be confident.B. Be careful.C. Be open- minded.D. Be hard- working.CPlastic is piling up in ecosystems all over the world. Although its harmful impacts on both species and ecosystems have been documented, a few animals—like bowerbirds and hermit crabs—are doing what they can to recycle it. And according to a recent study, wild bees in Canada have joined the effort, which is a rare observation of behavioral flexibility in species especially insects, in increasingly plastic-rich environments.The researchers found two species of leafcutter bees putting plastic into their nests. One of the bees they studied, the alfalfa leafcutter bee, normally bites off pieces of leaves and flowers while the second bee gathers sticky substances from trees. Leafcutter bees don't build big nests or store honey like honeybees, choosing instead small nests in underground holes, tree holes or cracks（裂缝）in buildings. But the researchers found that three of eight brood cells（育雏巢室）contained pieces of plastic bags, replacing 23 percent of the cut leaves in each cell on average.While they don't make honey,alfalfa leafcutter bees still make money for theU. S. and Canadian farmers by pollinating（给......传授花粉）crops including alfalfa , carrots and melons. The European insects were introduced to North America in the 1930s for that purpose, and they've since become wild, joining the continent's many native species of leafcutter bees.In a separate study conducted in Argentina between 2017 and 2018, researchers found a bee nest made entirely of plastic, which consisted of three separate cells. It's the first known example of such construction worldwide. Compared to the other nests the researchers examined, which were made of natural materials, this one had a pretty lower success rate of the bees' survival. One of the cells had a dead baby bee , another seemed to have housed an adult that had left the nest, and the third was unfinished.8. What does the animals' use of plastic show according to the study?A. How widely plastic is used.B. How strange the behavior of wildlife is.C. How some wildlife is adapting to plastic.D. How plastic pollution has harmed them.9. What do leaves mean to alfalfa leafcutter bees?A. Food.B. Shelter.C A plastic substitute. D. Traditional nest materials.10. Which is one characteristic of leafcutter bees?A. They have great economic value.B. They store honey like honeybees.C. They prefer to live in tree holes.D. They have evolved into a new species.11. What was the nest made entirely of plastic like?A. It might be warmer.B. It might be unhealthy.C. It might be easy to finish.D. It might be recyclable.DI’ve never been the kind of person to say, “it’s the thought that counts” when it comes to gifts. That was until a couple of weeks ago, when my kids gave me a present thatblew me away.For years now, I’ve been wanting to sell our home, the place where my husband and I raised our kids. But to me, this house is much more than just a building.In the front room, there’s a wall that has hundreds of pencil lines, marking the progress of my children’s growth. Every growth stage is marked in grey, with each child’s name and the date they were measured. Of all the objects and all the memories, it’s this one thing in a home that’s the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn’t normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our kids grow in so many ways, but the wall is physical evidence of their progress, right there for everyone to see. Over the years, I’ve talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my kids stopped growing.So one day, while I was at work, my childrendecided to do something about it.They hired Jacquie Manning, a professional photographer whose work is about capturing (捕捉) the beautiful things in life, from clear lakes and skies to diamonds and ballgowns (舞会礼服).She came to our house while I was at work, and over several hours, took photos of the hundreds of drawings andlines, little grey fingerprints (手印), and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, transforming them into a beautiful history of my family.Three weeks later, my children’s wonderful gift made its way to me—a life-size photo of the pencil lines and fingerprints that represents entire lifetimes of love and growth.12. The underlined phrase in Para. I “blew me away” probably means “________”.A. attracted meB. surprised meC. accepted meD. refused me13. What does the house really mean to the author?A. A house.B. Buildings.C. An object.D. Memories.14. What surprised the friends I know after work?A. Finding the wall repainted.B. Erasing the fingerprints.C. Greeting them by tears.D. Leaving the wall unfinished.15. What is the best title for the text?A. Gift Made with LoveB. Buildings Made by ChildrenC. A Very Wonderful PaintingD.

Rioghna, a junior at Rochester Mayo High School, had spring sports to play. Hannah, a senior at University of Chicago, was going to have a spring break in Aruba. However, both were canceled because of COVID-19. But they soon recovered and now they are sitting at home, solving Rochester's problemsin their way. Pointing to the computer screen, Hannah tells her sister, “She is a nurse and her child needs to be matched.”The two sisters birthed their plan last Saturday on the drive home from picking up Hannah in Chicago. As more medical workers were sent to work, fighting against the fierce pandemic (流行病), the sisters knew many of their families would need childcare. At the same time, teens throughout Rochester were off school. So on Sunday, Hannah and Rioghna launched Step Up To Sit. Already they’ve paired more than 40 families with sitters.“The young people in the community are stepping up to do their part,” Hannah says, “We are delighted that we’re having an impact on people’s lives in this hard time.” For the last four days, 160 teens have registered to help, most willing to work free if paired with a family in need. With more and more teens joining in, the two sisters decide to launch Step Up To Shop, a platform for teens to deliver groceries to seniors.Rioghna acknowledges people of her age get a bad reputation as smartphone-addicted and selfish. The Pittock sisters are proving otherwise.“Amid the pandemic, people should be allowed to be upset and allowed to be a little bit down about the upset in their lives, but it’s about something bigger and recognizing we all have our part to play here,” Rioghna says.4.

Which of the following best describes the two sisters?A.T olerant.B. Humble.C. Caring.D. Stubborn.7. What can be inferred from the last paragraph?A.S martphone addiction makes teens selfish.B.The Pittock sisters kept a low profile.C.People can do nothing against pandemic.D.T here is some misunderstanding of teens.CThe low percentage of women in science, technology, engineering, and mathematics (STEM) careers is often attributed (归因于)to men being believed to be better at the sort of thinking those fields require. Though studies have debunked the view, they have largely been based on results acquired from various several standardized tests. Now, researchers from Pennsylvania’s Carnegie Mellon University have found evidence that is hard to overlook: MRI (磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems.The groundbreaking study to evaluate the biological gender differences in themath talent of young children was led by the university’s professor of neuroscience, Jessica Cantlon. For their study, the team selected 104 young children, between 3 and 10 years old, divided almost equally by gender. The scientists used a functional MRI to observe their brain activity as they engaged in math tasks. These included watching age-appropriate educational videos and doing math exercises such as counting and addition, as well as reading for comparison.“We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non-math content like reading or the alphabet, ”Cantlon said. “When we do that in little girls, we see a particular network of the brain respond, and when we do that same analysis in boys, we see the exact same regions.”So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions. Previous studies have indicated that parentstend to spend more time with young boys in play that inspires spatial cognition (空间认知) — such as toys that involve learning number skills and shapes and solving puzzles. Educators werealso observed to spend more time with boys during math class.8. What does the underlined word “debunked” in paragraph 1 mean?A. Disproved.B. Supported.C. Confirmed.D. Overlooked.9. What does paragraph 2 mainly focus on?A. The purpose of the research.B. The process of the research.C. The participants of the research.D. The findings of the research.10. What contributes to the lack of women in STEM careers?A. Mental capacity.B. Gender difference.C. Traditional prejudice.D. Family background.11. What can be a suitable title for the text?A. MRI－A Great Helper in ResearchB. Toys－Boosters for STEM PotentialC. Boys and Girls: Equally Talented in MathD. STEM Careers: Calling for More WomenDAlgorithms (算法) affect nearly every part of a person’s experience on the Internet. Search engines are most people’s entry to the Internet. If a person wants to find information about something, they usually start with a search bar. As soon as they start typing or choosing links, the algorithm starts gathering data about every choice users make and uses that data to try to find the websites or information that most directly relate to what the user is looking for.The problem with algorithms is that they can limit the kinds of information people see, says MacMillan, a leading researcher with Project Information Literacy (能力). He argues this can be harmful to people’s critical thinking and lead them to believe that only one point of view is correct.Companies also pay to post advertisements for products that could relate to users’ search data. For example, if you search for places to take a vacation, you will likely start to see ads for travel companies, flights or hotels.Renee Hobbs, director of the Media Education Lab at the University of Rhode Island, however, argues that algorithms are not all bad. She says search engine algorithms can help you find what might be the most useful information faster. But she says it is in the interests of Internet companies to keep users on the Internet for as long as possible so they see more ads.The current generation of young people grow up using the Internet and they are prone (易于遭受) to distrustful information. That is why schools must train students how to use the Internet more wisely in their studies. It is the duty of education to keep students informed about the world around them. Yet it is not the duty of education alone. And lawmakers should consider increasing data protection rules. Individuals can also use a wide variety of websites to avoid algorithmic controls.12. How do algorithms affect users’ Internet experience?A. They lead to slower Internet connection.B. They block ads for users automatically.C. They always help users get reliable links.D. They determine the content users receive.13. What is Hobbs’ attitude to algorithms?A.D oubtful.B. Supportive.C. Objective.D. Indifferent.14. What can be concluded from the last paragraph?A. Young people fall victim to the Internet.B. Data protection rules are already enough.C. Education is fully responsible for algorithmic controls.D. Joint efforts are needed to handle algorithmic controls.15. Which column of a magazine is the text most likely from?A. Science.B. Entertainment.C. Advertisement.D. Fashion.第二节（共5小题；每小题2.5分，满分12.5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。

Cleaning up our polluted worldof plastic may seem a noble, but thankless task. However, some people are seeingeconomic opportunity in the mission.Plastic Bank, a social enterprise from Canada, is monetizing plastic recycling whileempowering those most affected by the waste. It works to prevent waste plastic fromentering oceans by encouraging people in developing countries to collect plastic from their communities in exchange for cash, food, clean water or school tuition for their children. After collection, plastic is weighed, sorted, chipped, melted into balls and sold on as“raw material”to be made into everything from bottles for cleaning products to clothing.“I saw in large quantities; I saw an opportunity,”CEO David Katz told the audience at the Sustainable Brands Oceans conference in Porto, Portugal on November 14.“We reveal the value in this material,”he added.Plastic Bank was founded in 2013 and launchedon the ground operations in 2014 in Haiti, the poorest country in the Western, Hemisphere, whereclose to 60% of the population live under the poverty line.As result ofpoor waste disposal and recycling infrastructure (基础设施)，plastic waste enters rivers or is burned and poses the health threats to the local residents.Thecompany says i has over 2,000 collectors working in the country, with its full- time collectors on average 63% above the poverty line thanks to the income they make from the project. Through its app based payment system, many collectors now have bank accounts for the first time, and are able to ultimately escape ultra poverty.“Nothing we're doing is against the laws of physics,”said Katz. “All the technology exists for us to solve and save the world. It's only creative thought.”8. What is Plastic Bank aimed to do?A. Test out creative ideas.B. Discover new material.C. Promote plastic recycling.D. Stop people using plastic.9.

Persuading consuming—reproducing.10. What do the numbers in Paragraph 5 indicate?A. Haiti attaches great importance to recycling.B. Many locals benefit greatly from the project.C. Collecting is an efficient way to recycle waste.D. Theproject has solved unemployment in Haiti:11. What maybe the best titleforthe text?A. Companies stand to ban plastic consumptionB. Technology finds its way to kick off povertyC. David Katz speaks at the conference in PortoD. Plastic Bank is fighting against plastic wasteDThey're life jacket orange, they re robots and they're capable of sailing the high seas without human intervention.On Tuesday the National Oceanic andAtmospheric Administration (NOAA) launched a pairof Saildrones(海洋无人机) in Pacific Northwestwaters for the firsttime. Their summer long sailing journey will stretchfrom Vancouver Island to California. The Saildroneoperators will collect data to help set future fishingseasons. The government wants tor see whetherseagoing. robots can extend fishery surveys now performed by expensive manned ships.Nora Cohen from NOAA said,“The 23 foot tong seagoing robots can follow a remotely programmed coursefor upto a year at a time. And they don't require any fuel. We use wind and solar power to drive the sensors.”He added,“It means that we're able to go toplaces where we don't really want to send people, and go into weather that we really don't want anyone ever to be in, and be able to send back measurements.”The primary mission is to investigate the species and number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25，000 per day. By comparison, one Saildrone runs $2,500 per day.“It could be a significant saving,”Hufnagle said. “But like anything else, there is a tradeoff in what you get and what you don't get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.”Nora Cohen said Sail Drone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different water bodies for NOAA this year. The Bering and Arctic seas, coastal California and Gulf ofMexico will be the locations of additional missions.12. What is the purpose of collecting fishdata?A. To explore the ocean.B. Toassist fishing industry.C. To learn thehabitsof fish,D. Toimprove fishing skills13. Whatis mainly discussed about the Saildrone in Paragraph3?A. Its advantages.B. Its appearance.C. Its power systems.D. Its primarymission.14.What does the underlined word “tradeoff”in Paragraph 5probably mean?A. Debate.B. Reason.C. Reality.D. Balance.15. What can be inferred from the text?A. The Saildrone has a promising future.B. Hufnagle thinks little of the Saildrone.C. Manned ships will be completely replaced.D. Production of seagoing robots is restricted.第二节(共5小题;每小题2.5分，满分12.5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。

2020年济南市第五中学高三英语三模试卷及参考答案

2020年济南市第五中学高三英语三模试卷及参考答案第一部分阅读（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AIt was a weeknight and one of my twin daughters marched into the room, waving a book she'd finished. “Dad, why are books with science in them always about boys?” she asked.I told her that simply wasn't true; there were loads of great science fictions with girls in them. She agreed, but argued that in those stories it was the boys who were doing science, and the girls were justalong for the ride. My other daughter took her sister's side and challenged me to give an example.This left me in a difficult position. I could either go through our library to point out some wonderful examples of female-led science fictions, or just admit they were right and remain in my comfortable chair.I've been asked several times how I came up with the idea forA Problematic Paradoxand my answer is always the same: it came to me in a moment of inspiration. I like that answer because it's simple and makes me seem very creative. The fact that this explanation is not true bothers me from time to time. Here's the truth: the story wasn't my idea. It was my daughters who suggested I write something for them that had a girl doing science.My daughters were at an age when many young women turn away from STEM (science, technology, engineering, and math), believing those areas of study unfriendly or out-of-the-norm for girls. I also read about how important role models can be to young people. It's one thing to tell a person they can do something, but seeing someone like them doing that thing can be more powerful.So, I kept two guidelines for the book in mind: First, the story had to be fun for anyone, because it's as important for boys to understand that science is for everyone. Second, I wanted the main character, Nikola, to be imperfect. She should be someone with shortcomings as we all have. I think this not only makes a story more interesting to read, but also helps make it clear that the most extraordinary things can be done by ordinary people.1. What does the underlined phrase “along for the ride” in paragraph 2 probably mean?A. Entering a bike race.B. Offering vital help.C. Doing unimportant things.D. Playing the leading role.2. What do we know about the bookA Problematic Paradox1?A. Its main character is perfect.B. It is a female-led science fiction.C. It is intended to appeal to girls only.D. Its idea comes from the author's inspiration.3. Which of the following best describes the author's book?A. Serious and abstract.B. Simple and practical.C. Creative and well-organized.D. Inspiring and interesting.BAccording to Oxford Dictionaries, morality means: “Principles concerning the distinction between right and wrong or good and bad behavior.” Though morality is a rather subjective subject, there are some principles that are universal across all cultures found by an Oxford University study: “help your family, help your group, return favors, be brave, obey superiors, divide resources fairly, and respect others’ property”. The fact that these morals are found across 60 cultures from around the world demonstrates that morality, though subjective, is the cornerstone of keeping our societies together. Here are some reasons to be moral: without morality, a social life is almost impossible to maintain; having a good reputation and having a clear conscience is psychologically healthy; and most philosophies regard unselfish and principled behavior as important.There is no doubt that without morals, a society cannot function effectively. A confused situation would appear, According to the Society of Morality, “We are social animals, and the actions we take-the things we do and the things we don’t do-have consequences on our environments and on the others around us. As a result, we need to be able to govern our behavior in the near term so as not to injure ourselves or our community in the long term. This system of controlling our actions and our thoughts in order to operate in a community is what we often refer to as morality”. Therefore, we need a set of morals in order to operate within a social circle and a social environment. Acting immoral usually results in being excluded from social activities or being avoided by a society based on laws and cultural standards. Besides acting moral having a sociological need, it also has a psychological basis. Most people are concerned to some extent about their reputation. According to PsyPost, “A lot of economic models of human behavior assume that people are only rational (理性的) when they narrowly pursue their own self-interest, but history shows us that people are also tremendously concerned with being and appearing moral”. So, the fear of one’s reputation being damaged is often a strong motivator to be moral. And if someonehas been immoral,most people go out of their way to make sure no one finds out, or to correct the behavior in order to not be caught. This goes in line with conscience as well. People generally feel in a better psychological state if they feel that their conscience is clean. A dirty conscience can result in a lack of sleep, anxiety, internal stress, and even illness.On the side of philosophy, the study of ethics (伦理) comes into play. Most philosophers agree that one should rationally choose a set of standards of behavior in order to function. Though there is moral relativism,there are universal anthropological (人类学的) morals, as mentioned in the introduction. By the nature of our societies and cultures, we choose what we believe is right and wrong. But surprising, this rational behavior comes to a general agreement on morals. So, there is a fine line between moral relativism and moral absolutism. But the main thing to take away from this discussion is that philosophers generally believe that each individual has the right to rationally come up with a set of ethics to live by, and that it is healthy to do so.4. The author discusses morality (paragraph 1) in order to ________.A. explain the relationship between morality and cultureB. describe the moral rules found all around the worldC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality5. It can be inferred from the passage that ________.A. acting moral allows us to fit into group betterB. morality brings the system of controlling behaviorC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality6. Which of the following is the psychological basis for acting moral?A pursuit of self-interest. B. a clean conscience.C. The concern about reputation.D. a dirty conscience.7. What does the author advise us to do according to the last paragraph?A. To reach a general agreement on morals based on ethics.B. to carve one’s own sense of ethics to operate in this world.C. To choose between moral relativism and moral absolutism.D. To exclude philosophers’ beliefs and solution as well.CWho is a genius? This question has greatly interested humankind for centuries.Let's state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It's said that history is written by the victors, and those victors set the standards foradmission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color1 or belief—they were unacknowledged and rejected by others.A study recently published bySciencefound that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found thatgirls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: ly not.Here's the good news. In a wired world with constant global communication, we're all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”8. What does the author think of victors' standards for joining the genius club?A. They're unfair.B. They're conservative.C. They're objective.D. They're strict.9. What can we infer about girls from the study inScience?A. They think themselves smart.B. They look up to great thinkers.C. They see gender differences earlier than boys.D. They are likely to be influenced by social beliefs10. Why are more geniuses known to the public?A. Improved global communication.B. Less discrimination against women.C. Acceptance of victors' concepts.D. Changes in people's social positions.11. What is the best title for the text?A. Geniuses Think AlikeB. Genius Takes Many FormsC. Genius and IntelligenceD. Genius and LuckDIf you ever find yourself trapped in the wilderness without food, you'llhave to figure out how to feed yourself.Many plants in the wild areedible, but many are also poisonous. So it is necessary to learn how to determine whether the plants you find can be eaten safely.Avoid using this method without careful planning. Some plants can be deadly, and even if you follow these guidelines perfectly, there is always a chance that a plant will make you seriously ill. Prepare yourself for wilderness outings by learning about the local plants, and carry a guidebook to help you identify plants. Even if you are unprepared and cannot find food you know to be safe, remember that, depending on your activity level, the human body can go for days without food, and you’re better off being hungry than being poisoned.Testing the plant in your mouth is dangerous, so go forward very slowly and carefully. First, hold a small portion of the prepared plant part against your lip for 3 minutes. Do not put the plant in your mouth. If you notice any burning, tingling (刺痛), or other reactions, discontinue testing. Second, place another small portion of the plant part on your tongue. Hold the plant on your tongue without chewing for 15 minutes. Discontinue testing if you notice any reaction. Third, chew the plant and holdit in your mouth for 15 minutes. Chew the plant well, and do not swallow. Discontinue testing if you notice any reaction. Fourth, swallow the small portion of the plant. Wait 8 hours. Do not eat or drink anything during this period except purified water. If you feel sick, immediately throw up what you eat and drink plenty of water. If activated charcoal (活性炭) is available, take that with the water.12. What’s the meaning of the underlined world “edible” in paragraph 1?A. Suitable for using as food.B. Widely spread.C. Existing in large quantities.D. Not widely known.13. What can we know from paragraph 2?A. Planning is unnecessary when using the method.B. Not all plants in the wild can serve as food generally.C. Suffering hunger can be more dangerous than testing plants.D. Following the method perfectly can ensure safety.14. Which is the correct order of testing plants in the mouth?① wait and see ② chew it in the mouth③ put it on the tongue④ put it against lips ⑤ swallow itA. ③④②①⑤B. ④③②①⑤C. ③④②⑤①D.④③②⑤①15. Where might the passage come from?A. A student’s diary.B. A science report.C. A guide book for camping.D. A doctor’ s notebook.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。

Cleaning up our polluted world of plastic may seem a noble, but thankless task. However, some people are seeing economic opportunity in the mission.Plastic Bank, a social enterprise from Canada, is monetizing plastic recycling while empowering those most affected by the waste. It works to prevent waste plasticfrom entering oceans by encouraging people in developing countries to collect plastic from their communities in exchange for cash, food, clean water or school tuition for their children. After collection, plastic is weighed, sorted, chipped, melted into balls and sold on as“raw material”to be made into everything from bottles for cleaning products to clothing.“I saw in large quantities; I saw an opportunity,”CEO David Katz told the audience at the Sustainable Brands Oceans conference in Porto, Portugal on November 14.“We reveal the value in this material,”he added.Plastic Bank was founded in 2013 and launched on the ground operations in 2014 in Haiti, the poorest country in the Western, Hemisphere, where close to 60% of the population live under the poverty line. As result of poor waste disposal and recycling infrastructure (基础设施)，plastic waste enters rivers or is burned and poses the health threats to the local residents.The company says i has over 2,000 collectors working in the country, with its full- time collectors on average 63% above the poverty line thanks to the income they make from the project. Through its app based payment system, many collectors now have bank accounts for the first time, and are able to ultimately escape ultra poverty.“Nothing we're doing is against the laws of physics,”said Katz. “All the technology exists for us to solve and save the world. It's only creative thought.”8. What is Plastic Bank aimed to do?A. Test out creative ideas.B. Discover new material.C. Promote plastic recycling.D. Stop people using plastic.9. Which of the following shows the process of monetizing in Paragraph 2?A. Purchasing- collecting—recycling.B. Exchanging collecting—purchasing.C. Collecting- exchanging—reproducing.D. Persuading consuming—reproducing.10. What do the numbers in Paragraph 5 indicate?A. Haiti attaches great importance to recycling.B. Many locals benefit greatly from the project.C. Collecting is an efficient way to recycle waste.D. The project has solved unemployment in Haiti:11. What maybe the best title for the text?A. Companies stand to ban plastic consumptionB. Technology finds its way to kick off povertyC. David Katz speaks at the conference in PortoD. Plastic Bank is fighting against plastic wasteDThey're life jacket orange, they re robots and they're capable of sailing the high seas without human intervention.On Tuesday the National Oceanic andAtmospheric Administration (NOAA) launcheda pair of Saildrones(海洋无人机) in PacificNorthwest waters for the first time. Theirsummer long sailing journey will stretch fromVancouver Island to California. The Saildroneoperators will collect data to help set future fishing seasons. The government wants tor see whether seagoing. robots can extend fishery surveys now performed by expensive manned ships.Nora Cohen from NOAA said,“The 23 foot tong seagoing robots can follow a remotely programmed course for up to a year at a time. And they don't require anyfuel. We use wind and solar power to drive the sensors.”He added,“It means that we're able to go to places where we don't really want to send people, and go into weather that we really don't want anyone ever to be in, and be able to send back measurements.”The primary mission is to investigate the species and number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25，000 per day. By comparison, one Saildrone runs $2,500 per day.“It could be a significant saving,”Hufnagle said. “But like anything else, there is a tradeoff in what you get and what you don't get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.”Nora Cohen said Sail Drone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different water bodies for NOAA this year. The Bering and Arctic seas, coastal California and Gulf of Mexico will be the locations of additional missions.12. What is the purpose of collecting fish data?A. To explore the ocean.B. To assist fishing industry.C. To learn the habits of fish,D. To improve fishing skills13. What is mainly discussed about the Saildrone in Paragraph 3?A. Its advantages.B. Its appearance.C. Its power systems.D. Its primary mission.14.What does the underlined word “tradeoff”in Paragraph 5 probably mean?A. Debate.B. Reason.C. Reality.D. Balance.15. What can be inferred from the text?A. The Saildrone has a promising future.B. Hufnagle thinks little of the Saildrone.C. Manned ships will be completely replaced.D. Production of seagoing robots is restricted.第二节(共5小题;每小题2.5分，满分12.5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。
