2019-2020学年滨州市邹平一中高三英语上学期期末试卷及答案解析第一部分阅读(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AOn Friday morning when 53-year-old Thong Pham broke into the house through the unlocked back door, he took a steak knife from the kitchen.It was dark, and the family didn't know what Marley was barking (吠) at. Taylor, Amber and their girls Finley, 6,and Sadie, 4, soon woke up and came downstairs, too. “Well, it was dark so we couldn't see anything, only could hear Marley,” Amber recalled, saying her husband then went for the lights. “And once he turned the hall light on, we realized that the guy was holed up in the corner trying to hide.”“So I think he got to the front door and realized he couldn't get out, and by that point in time, Marley's got him cornered,”Taylorsaid. Pham slashed (砍) both Marley and Taylor, and blood went everywhere. Taylor shared a video summary to his Facebook page, where he said Marley was stabbed (刺) up to six times, mostly around the head and neck area. “And as I pulled back, blood shot out of my arm,”Taylorcontinued. “She got him pretty good and I got him pretty good in the face.”“But it was really hard because I was trying to make sure that my husband wasn't going to die,” Amber explained, adding that she was trying to protect their two girls. “When he realized that the two girls were in the house, that's when he kind of backed up and started running. "Taylorexpressed gratitude to everyone for their thoughts and prayers. And the family is thankful for their dog Marley.“She's our hero,” Amber said. “If it hadn't been for her, that guy could have gone in the...he could have gone to their rooms or something.”Tayloradded, “Yeah, I mean, the story plays out very differently if Marley's not there.”1. Why did the family come downstairs before daybreak?A. To stop a break-in.B. To lock the back door.C. To check on Marley.D. To turn the hall light on.2. What happened during the fight?A. Pham dug a hole in the corner.B. Marley was injured but bit back.C. Taylor had a backup from neighbors.D. Amber fought back to protect her girls.3. What doesTaylormainly express on his Facebook?A. Forgiveness.B. Concern.C. Anger.D. Appreciation.BLast summer, I spent four months working in France, where the company I was working for put me up in a house that didn’t have Wi-Fi. I wasn’t looking forward to it.I soon discovered, however, that living in a house without Wi-Fi was easier than I expected.Contact between my friends and family was significantly reduced to the odd text message here and there. I couldn’t enjoy my usual web browsing on BBC iPlayer, social media sites, keeping up to date with the news, or even wanting to know the opening hours of shops in the new area I was in.I didn’t, however, spend a full four months without connecting to a Wi-Fi network. It was only a five minute walk to the reception where I could connect for free and spend as much time online as I wanted to at my own leisure. It made me think , though , how unnecessary it can be , how unnecessarily we rely on it—how we perhaps rely on it too much. As a person, I was more sociable. I spent more time with my housemates instead of hiding behind a computer screen. I did other things that I wouldn’t necessarily have done if I could have browsed the web at my leisure. I read more, I cooked meals for my friends, and I even tidied up more often. Dare I say it; I learned how to live without Wi-Fi. Dare I say it; I found it was easier than I had imagined.4. What was the writer’s first feeling when finding her house had no Wi-Fi?A. Unexpected.B. Angry.C. Shocked.D. Depressed.5. How did the writer keep in touch with her friends and family without Wi-Fi?A. By writing regularly.B. By text message.C. By video calls.D. By telegram.6. What was the writer’s life like without Wi-Fi?A. Dull.B. Lonely.C. Active.D. Relaxing.7. What can be a suitable title for the text?A. A life without Wi-FiB. Different views on the InternetC. The disadvantages of Wi-FiD. How to use the InternetCEarthquake can disrupt whales’ hunting for food for up to a year,according to a new study.On November 14, 2016, the Kaikoura earthquake struck New Zealand’s South Island, causing a destructive tsunami. Under the surface, the earthquake caused strong currents that swept away and mostly killed off diverse ecosystems of creatures living along the Kaikoura underwater canyon.As a result, whales had to dive deeper and longer to find food—“a major shift” in their behavior, says co-author Liz Slooten, a marine biologist at the University of Otago in New Zealand.The impact earthquakes have on land animals has been well documented, but scientists know ly little about what happens underwater. Such research is important for government agencies, which may need to take recent earthquakes into consideration when considering fishing quotas(限额), notes Rochelle Constantine, a marine mammal ecologist at the University of Auckland.The canyon’s upper reaches are rich in creatures, supplying food for the fish that make up the whales’ diet. So when these smaller life forms were washed away, it had “severe consequences for the community around there”, says study co-author Will Rayment. “That effect flowed all the way through the food chain.”As part of their ongoing study, the scientists were tracking 42 individual whales. After the earthquake, in all, the team managed to record data on 40 whales, showing that the abundance of whales in the general area didn’t change after the earthquake. However, the whales changed how they used their habitat.A year after the earthquake, the researchers observed the whales returning to their previous surface-breathing intervals. This could have been because the communities of animals that make up the whales’ food began to recover. “It gives you an idea of how resilient(有复原力的)these deep-sea communities are,” says Rayment.But he and his colleagues will continue long-term monitoring to see if there are effects they missed. Whale activity in the area had already been declining, though it’s unknown whether it is due to natural changes in food abundance, whale-watching tourism, fishing, or warming ocean temperatures. “There is something going on in Kaikoura,” says Rayment.8. What happened after the Kaikoura earthquake in the Kaikoura canyon?A. Several destructive tsunamis struck the area.B. Whales had to swim to other oceans to find food.C. Nearly all marine creatures in Kaikoura were killed off.D. Strong currents washed away many smaller creatures.9. Which is one of the findings of the study?A. Earthquakes can make it easier for whales to find food.B. The whales changed their habitat after the earthquake.C. It usually takes whales a year to adapt to their new diet.D. The number of whales in the area dropped sharply after the quake.10. What does Rochelle Constantine think of the study?A. It can help government agencies to make some decisions about fishing.B. It can help government agencies to solve problems in the fishing industry.C. It is a breakthrough in research on what happens underwater after an earthquake.D. It offers a detailed description of the impact earthquake have on marine mammals.11. What can we infer from the last paragraph?A. Something is affecting the whale activity in Kaikoura.B. Fishing quotas have been increasing in recent years.C. The team missed some effects in the research process.D. The scientists will continue studying earthquakes.DAccording 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 socialenvironment. 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.12. 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 morality13. 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 morality14. 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.15. 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.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。

It’s the routine exercise for students of Mianyang Foreign Languages Experimental School in Sichuan province.“Sichuan Opera is a local opera, and it is now facing a gap in inheritance (传承). Therefore, we cooperated with Mianyang Intangible Cultural Heritage Center to create a simple and easy-to-learn Sichuan Opera exercise,” said Shen Junhua, who is in charge of organizing the school’s exercise between classes.According to Shen, this new type of exercise has been practiced since 2017 and has been popular among students. When students enroll (入学), they will spend several weeks practicing it. At present, almost all of the students and teachers have mastered it.“In fact, we had hardly heard of Sichuan Opera before teachers taught us how to do the Sichuan Opera exercise,” said Li Yangwenwen, 14, an eighth grade student who also joined the school’s Sichuan Opera club out of interest. “It’s very different from normal exercises. After practicing it, we found it very beautiful and became interested in it. Now, almost all of the students look forward to our daily exercise time and feel excited to do it.”“By combining opera with daily exercise, the daily class activity allows students to perceive and understand Sichuan Opera’s culture”, Shen said. “After years of continuous effort to spread the seeds of traditional culture, the younger generation is finally catching on.”4.

The students can better understand their local culture.D. Students help to spread the seeds of traditional culture toyounger generation.CIn the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact(影响)on the environment. After all, you were jumping into your car, driving across town, coughing out emissions(产生排放)and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers(where videos are stored)there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.Streaming is only expected to increase as webecome more enamored ofour digital devices(设备)and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because itconsumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.8.

Playing online games over mobile networks.DEven as Google plans to test its fleet (车队) of self-driving cars on public roads this summer, its business model remains abit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm.“Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people,” said Chris Urmson, director of Google’s self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google’s headquarters inMountain View,California. Previous testing has taken place only on closed courses.The cars are built to operate without a steering wheel, accelerator (油门) or brake pedal. “Our software andsensors do all the work,” Urmson said. “The vehicles will be very basic — we want to learn from them and adapt them as quickly as possible — but they will take you where you want to go at the push of a button.” The prototype (雏形) is the first of a 100-car fleet the tech giant is building.In the long run, Urmson sees a future of safer roads — the majority of auto accidents are caused by human error — and fewer traffic jams. Robotic cars could also shuttle people who can’t drive because of age or illness.Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don’t own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.The state has issued six other companies permits to operate such cars, includingDelphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow “safety drivers” to take control if needed.12. According to Chris Urmson, __________.A. self-driving cars can give driving orders to humansB. self-driving cars are specially designed for the elderlyC. software and sensors are vital for self-driving carsD. ordinary vehicles will be replaced by self-driving cars13. Paragraph 4 is meant to tell us that __________.A. many traffic accidents are caused by human errorB. some people can’t drive because of illness or ageC. Urmson has promised to create safer roads in the futureD. self-driving cars will probably help to make safer roads and decrease traffic jams14. The underlined word “issued” in the last paragraph can probably bereplaced by__________.A. givenB. claimedC. awardedD. prohibited15. What’s the author’s attitude towards self-driving cars?A. Objective.B. Indifferent.C. Subjective.D. Favorable.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。
