But one thing that must be kept in mind is that when we ask others for suggestions we must be open to suggestions.I wrote a business letter one day. I gave it to my husband for suggestions. After reading the letter, he felt that there were some problems in my letter. I told him I needed more information, but he said he wasn’t sure. Then he reread the letter and made notes. I took the letter andrevised it. As I was writing, I could see my letter improved based on his suggestions. Again, I handed the letter back to my husband proudly and confidently. But he said it was still not right.I was a little annoyed and said some bad words to him.Many people may have the same reaction when they experience the same situat ion. It’s normal that people don’t like objection or critical words. However, we should hold a right attitude towards these words：Analyze the objection and listen to critical words with an open mind.I then picked up the letter. After an hour of revision, I went back to my husband contritely. I told him I was sorry for what I had said. And after he read the letter again, he declared that it was fine.That leads me to the following：When you ask for advice on a project, be grateful. Understand that the suggestions you get may be negative. Understand that it may mean more work for you. And keep in mind that the final responsibility for the project is still yours. So be modest and thankful even if he or she has noted some problems.4. Why did the author give her business letter to her husband？A. T o show off her excellent work.B. To ask him to make some changes.C. T o have him type it on the computer.D. T o ask him to give her some advice.5. What kind of people is the author’s husband？A.

Don’t get upset if some are negative.B. Don’t refuse any help from the giver.C. Do keep silent before taking action.D. Don’t quarre l but talk with the giver.CA new app aims to help parents understand what their baby wants based on the sound of their cry. The free app ChatterBaby, which was released last month, analyzes the acoustic （声学的）features of a baby’s cry, to help parents und erstand whether their child might be hungry, or in pain. While critics say caregivers should not rely too much on their smartphone, others say it’s a helpful tool for new or tired parents.Ariana Anderson, a mother of four, developed the app. She originally designed the technology to help deaf parents better understand why their baby was upset, but soon realized it could be a helpful tool for all new parents.To build a database, Anderson and her team uploaded 2,000 audio samples of infant（婴儿）cries. She used cries recorded during ear piercings and vaccinations to distinguish pain cries. And to create a baseline for the other two categories, a group of moms had to agree onwhether the cry was either hungry or in pain.Anderson’s team continues to collect dat a and hopes to make the app more accurate by asking parents to get specific about what certain sounds mean.Pediatrician Eric Ball pointed out that evaluating cries can never be an exact science. “I think that all of the apps and technology that new parents are using now can be helpful but need to be taken seriously,” Ball said ,“ I do worry that some parents will get stuck in big data and turn their parenting into basically a spreadsheet （电子表格） which I think will take away the love and caring that parents are supposed to be providing for the children. ”But Anderson said the aim of the app is to have parents understand the results, not to provide a yes or no answer. The Bells, a couple using this app, say it’s a win-win. They believe they are not only helping their baby now but potentially others in the future.8. How does the app judge what babies want？A. By collecting data.B. By recording all the sounds.C. By analyzing the sound of their cries.D. By asking parents about specific messages.9. What was the app designed for in the beginning？A. All new parents.B. Deaf parents.C. Ariana Anderson.D. Crying babies.10. What is Ball’s opinion about the app？A. Parents should use the app wisely.B. The app can create an accurate result.C. Parents and babies are addicted to the app.D. The app makes babies lose love and caring.11. What is the text mainly about？A. Parents should not rely too much on their smartphones.B. A new app helps parents figure out why their babies are crying.C. Parents can deal with babies’ hunger with the help of a new app.D. A new app called ChatterBaby can prevent babies from crying.DHarvard researchers have created a tough, low-cost, biodegradable（可生物降解的） material inspired by insects’ hard outer shells. The material’s inventors say it has a number of possible uses and some day could provide a more environmentally friendly alternative（可替代的） to plastic. The material, made from shrimp shells and proteins produced from silk, is called “shrilk”. It is thin, clear, flexible（柔韧性的） and strong.A major benefit of the material is its biodegradability. Plastic’s toughness and flexibility represented a revolution in materials science during the 1950s and 1960s. Decades later, however, plast ic’s durability（耐用性）is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years？Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer, and so will enrich the soil. Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible if it should be used for products demanding a lot of material.Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they’re exploring ways to use it in wet environments. They’re also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They’re even exploring combining it with other materials, like carbon fibers, to give it new properties.12. Paragraph 1 of the passage is mainly about shrink’s .A. remarkable designB. interesting nameC. major featuresD. basic elements13. According to the inventors, shrilk has great potential partly because .A. it can help plastic degradeB. it can be found in living thingsC. its mass production has been realizedD. its raw materials are abundant in nature14. What are the inventors doing in the lab？A. Replacing carbon fibers with shrilk.B. Testing shrilk’s use in wet conditions.C. Making shrilk out of used household goods.D. Improving shrilk’s f lexibility for medical purposes.15. Which of the following can be the best title for the passage？A. Recent Progress in Environmental Protection.B. Benefits of Insects in Scientific Research.C. The Harm of One-time Products.D. A Possible Alternative to Plastic.第二节（共5小题，每小题2分，满分10分）阅读下列一篇短文，根据短文内容，从短文后的A、B、C、D、E、F、G 7个选项中选出能填入空白的最佳选项，并在答题卡上将该项涂黑,选项中有两项为多余选项。

Here are some hottest travel destinations that offer some of the most beautiful, artistic, and fashionable places on the globe.Ibiza, SpainWhile Ibiza is knownas a party city, there is far more to do in this historic town than simply drink and dance under the stars. Built mainly in the second century, it’s a world heritage site with architecture dating back to as early as the 7th century. Don’t miss Charo Ruiz, Ibiza’s most famous fashion brand. Plus, the Ibiza Fashion Festival takes place every June.Tangier, MoroccoKnown as the “door to Africa”, Tangier has a rich and complex history dating back thirty centuries.

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 and sensors 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.4. 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 cars5. 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 jams6. The underlined word “issued” in the last paragraph can probably bereplaced by__________.A. givenB. claimedC. awardedD. prohibited7. What’s the author’s attitude towards self-driving cars?A. Objective.B. Indifferent.C. Subjective.D. Favorable.CCoke was introduced by the Coca Cola company in 1886, making it a rather true andtested favorite of generations of people in over 200 countries. This list should give you some ideas on how to get more from your coke than usual.. Coca Cola is an excellent rust buster (除锈剂). If you have a bunch of small rusty objects, put them in coke overnight and give them a goodscrubin the morning. Coke helps to break down the rust, making cleaning much easier. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.. Like the previous item, the citric acid (柠檬酸) in coke makes for an excellent window cleaner. This is especially useful for car windows. Pour a can of coke over the window and rub the window, then wipe it off with a wet cloth to remove any sugary matter from the sugar in the drink. As coke is fullof sugar, you should clean the sticky matter off the window glasses, or it will be not a cleaner but a dirt.. For those of you who live in areas where skunk (臭鼬) smells can be an issue from time to time, one can of coke added to water with detergent (清洁剂) really helps to break the smell down. If you have been sprayed, stand in the shower and cover yourself from head to toe with coke — wait for a few minutes, then wash yourself with a shower. Coke is an excellent hair treatment so you get two tips for the price of one with this item!. Pots can sometimes get black on the bottom. The black is almost impossible to remove; this is caused by over-cooking. To remove the black and renew your pot, pour in a can of coke (or as much as you need to cover the blackened area by an inch) and put it on the stove on a low heat. After an hour or so, wash the pot as normal.8. What does the underlined word “scrub”in Paragraph 2 probably mean?A. Start.B. Cleaning.C. Shake.D. Example.9. What is important while using coke to clean car windows?A. Use a dry cloth.B. Rub the window lightly.C. Don’t pour too much coke.D. Clean the sugary matter thoroughly.10. For which purpose does coke have to be mixed with other material?A. To get rid of the black on the pot.B. To breakdown the rust,C. To remove smells.D. To clean windows.11. What type of writing is this text?A. An advertisement.B. A review.C. A news report.D. A practical guide.DOne Sunday morning, my family and I went to a popular restaurant for breakfast. As soon as we walked into Restaurant Happy Meal, a young waitress showed us to a table.We ordered our food and soon after, our food came. Just as we were about to begin our meal, we heard someone shouting for the boss.“What is this? A dead fly in my food!’’ a man with a deep scar (疤) acrosshis face shouted angrily. He strongly hit his fist on the table and swept the plates and cups off it.Thesecame crashing to the floor, breaking into pieces. His companion, a huge man with a tattoo on his arm, stared angrily at the boss who stood nervously in front of the two gangsters (歹徒).The boss apologized repeatedly to the angry customers and tried to calm them down by offering to replace their food. He even told them that they could have their meal for free.The commotion(混乱) affected the business of the restaurant. Fearing that aquarrel would happen, many customers quickly paid for their meals and left the restaurant hurriedly. Some of them had not even finished their breakfast.My father told us to eat our food quickly and not to look at the two angry men. We obeyed him and finished our food within minutes. That was probably the quietest and fastest breakfast my family ever had.Although my father warned us not to look at the two unruly (任性的) customers, I could not help stealing a glance at them.I saw that the boss had managed to calm the two angry customers. Fresh food and drinks were brought to their table. They sat down again and continued their breakfast. Meanwhile the waitress who had shown us to our table earlier swept up the broken china.12. What does the underlined word “These” refer to?A. Tables.B. Cups and plates.C. Two angry customers.D. Dead fly and the food.13. What can we know about the owner from paragraph 4?A. He was sorry for what had happened.B. He was angry with the two customers.C. He was pardoned by the two customers.D. He was disappointed that the men caused problems here.14. What can we infer about the writer and his family?A. They might often talk while they ate.B. They ordered a lot of food each time they ate out.C. They often ate silently and that day was no exception.D. They usually did not like to be disturbed while they ate.15. What did the writer think of the boss?A. Foolish.B. Active.C. Hardworking.D.

2020-2021学年深圳高级中学高三英语期中考试试题及答案
2020-2021学年深圳高级中学高三英语期中考试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.BEarthquake 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.4. 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.5. 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.6. 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.7. 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.CWhen Jennifer Doudna was in sixth grade, she came home one day to find that her dad had lefta book titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved.On a rainy Saturday, she picked up the book. As she sped through the pages, she became fascinated by the drama, which encouraged her to explore nature's wonders. Even though her high school teacher told her that girls didn't become scientists, she decided she would.She worked with a biologist, Charpentier, to turn a curiosity of nature into an invention—an easy-to-use tool that can edit DNA. Known as Crispr, the tool will transform the human race. James Watson, the author of The Double Helix, later told her it was the most important biological advance: since he and Francis Crick discovered the structure of DNA.For this achievement, Doudna and Charpentier were awarded the Nobel Prize in Chemistry in 2020. Until now, only five women, beginning with Marie Curie in 1911, had won or shared the Nobel for Chemistry out of 184award winners. When this year's prize was announced, Dr. Charpentier said it would provide a message specifically to young girls who would like to follow the path of science and to show them that women can also be awarded prizes.A few decades from now, if it becomes possible and sate to edit DNA, should we allow parents to improve the IQ and physical strength of their kids? Should we let them decide eye color1 ? Skin color1 ? Height? After helping to discover Crispr, Dr. Doudna has become a leader in considering these moral issues. That's the main message we should take from this Nobel: New technologies can be a huge benefit to the human race, but in order to make sure they are used wisely, it's important for people to understand them.8. Jennifer Doudna decided to become a scientist because,__________A. her father pushed herB. a book inspired herC. her teacher encouraged herD. James Watson motivated her9. Dr. Doudna was awarded the Nobel Prize because,__________.A. she wrote the book “The Double Helix"B. she discovered the structure of DNAC. she is a hardworking woman scientistD. she helped invent a tool for editing DNA10. According to passage, which of the following is NOT true?A. The two women's success will inspire more girls to be devoted to science.B. Since 1911, there have been 184 people who won the Nobel for chemistry.C. If girls follow the path of science, they will surely achieve their goals.D. Crispr will make a big difference to the human race.11. Which words can best describe Jennifer Doudna?A. Determined and responsible.B. Ambitious and humorous.C. Cruel and indifferent.D. Fearless and stubborn.DChildren's average daily time spent watching television or using mobile device increased from 53 minutes at age 12 months to more than 150 minutes at 3 years, according toan analysis by researchers at the National Institutes of Health (NIH). By age 8, children were more likely to log the highest amount of screen time if they had been in home-based children or were born to first-time mothers.“Our results indicate that screen habits begin early, ”said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD).“This finding suggests that interventions(干涉) to reduce screen time could have a better chance of success if introduced early.”In the research, mothers of 4, 000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age.TheAmericanAcademyof Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding (超过) these recommendations. However, while screen time increased throughout toddlerhood, by age 7 and 8, screen time fell to under 1.5 hours per day. The researchers believe this decrease relates to time consumed by school-related activities.The study authors classified the children into two groups based on how much their average daily screen time increased from age 1 to age 3. The first group, 73% of the total had the lowest increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the highest increase, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with lower odds of inclusion in the second group.12. Who use mobile device longest according to the NIH's analysis?A. 10-year-old born to first-time mothers.B. 3-year-old children in low income families.C. 8-year-old children in home-based childcare.D. 1-year-old children with parents poorly educated.13. What does the research suggest according to Edwina?A. Parents should stop their children using media.B. Parents should limit the use of digital media themselves.C. Parents should reduce their children's screen time earlier.D. Parents should avoid their children using digital media at infancy (婴儿期).14. Why does children's screen time fall when they age 7 and 8?A. They are studying at school.B. They can control themselves.C. They are tired of using them.D. They are forbidden to use them.15. Which of the following may be the best title?A. Keep Away from MediaB. Screen Habits Begin EarlyC. Urgency of Parental EducationD.

What will a skiing beginner who wants to enjoy himself prefer to choose?A. Blue SquareB. Black DiamondC Double Black Diamonds D. Green CircleBMy first week working in a restaurant, one of the servers said something that stuck with me: Everyone should work in a restaurant for at least a year. At the time, I didn't get it, but I took the advice to heart and worked in restaurants on and off for the next eight years. Before realizing it, I mastered many important skills, one of which is communication skill.When I was little, I was so shy that I used to hide behind my mom whenever someone spoke to me. And when I first started in restaurants, I had two personalities: Restaurant Lizzy and Home Lizzy. It was easier to pretend to be a different person while at work, since it was so different from who I actually was. But gradually, the skills I learned working in restaurants helped Home Lizzy come out of her shell in the real world.When you work in a restaurant, you don't have the luxury of hiding behind your parents to avoid talking to people. I'm still 110% an introvert, but restaurant work helped me communicate. Working in a restaurant not only helped me speak clearly, deliberately and directly but also taught me how to talk about almost everything. Some guests don't want their servers to interact too much with them, and that's fine. But some sit at the bar simply to chat with you. You learn how to judge your guests' level of interest in communicating with you, and how to exit a conversation at the appropriate time.My restaurant work is something that I'm most proud of and I know I wouldn't be the person I am today without those eight years of experience. If you're still on the fence about working in a restaurant for that long, start with one year. I doubt that you'll look back.4. What did the writer think of the server's words?A. Impressive.B. Ridiculous.C. Amusing.D. Logical.5. What do we infer from Paragraph 2?A. The writer tried different jobs.B. The writer became more sociable.C. The writer used an invented name.D. The writer had a hard time at work.6. Which of the following best describes the writer's restaurant work?A. Boring.B. Relaxing.C. Worthwhile.D. Unchallenging.7. What message does the writer try to convey in this passage?A. A strong-willed soul can reach his goal.B. Things are difficult before they are easy.C. Communication skills advance your career.D. Restaurantwork helps to achieve a better self.CAn unmanned Chinese spacecraft left the earth on a trip to the planet Mars on Thursday. The launch（发射）marks the start of one of China's most important space explorations. China's national space agency launched the spacecraft called Tianwen-1 fromthe Wenchang Spacecraft Launch Center on Hainan Island.The name Tianwen means “Questions to Heaven” in Chinese. The spacecraft took off on China's largest carrier rocket, the Long March 5, and about 36 minutes later, the spacecraft, including an orbiter（轨道飞行器）and a rover（漫游车），was sent into the Earth-Mars orbit. It is expected to reach the orbit of the red planet next February. Tianwen-1 will finish three scientific goals—orbiting the red planet, landing on the Mars and sending a rover to the landing site.Tianwen-1 carries several scientific instruments to observe the planet's atmosphere and surface. It will do a series of scientific researches on the planet's soil, geological structure, environment, atmosphere and water. Besides its daily work of exploring the surface of Mars for 90 days, it will also report back to the earth about its experiences on the red planet, which is millions of miles away. According to experts, discovering signs of life will be its first and most important scientific goal.Tianwen-1's successful landing will make China the second nation to place a spacecraft on Mars. The United States has landed eight vehicles on Mars since 1976. China will be the first to successfully orbit, land and place a vehicle in the same mission. This is China's first independent mission to Mars. The task in 2011 failed when a Russian rocket carrying a Chinese orbiter had problems after launch, and was unable to escape the Earth orbit.Last year, China's Chang e-4 spacecraft became the first to make a landing on the far side of the moon.8. When will Tianwen-1 enter the orbit of Mars?A. 36 minutes later.B. Next Thursday.C. In 90 days.D. Next February.9. What is the main task of Tianwen-1 according to experts?A. Orbiting the Mars.B.

Tianwen-1 is the second vehicle landed on the Mars.B. The United States is the first to land vehicles on the Mars.C. Russia helped China place Tianwen-1 on the Mars.D. Chang，e-4 was the first to make a landing on the moon.11. Where can you find this article?A. In a newspaper.B. In a diary.C. In a sci-fi novel.D. In a guide book.DDolores Huerta has worked hard most of her life to help other people. She has helped change things so that others can have a better life.Dolores grew up in California.

One Wednesday afternoon, I was ever suggesting places to which he could take me for lunch when he interrupted （打断）me. "Rose" he said, "have you ever thought of taking me out to lunch? I would like to be wined and dined, too, and it would be nice if, for once, you picked up the check." I smiled at his words and said, "OK, but I'll choose the restaurant."I drove us to Miller's Ale House, a family-style restaurant with good food and an affordable menu that we attend only during the daytime. As Mike and I walked in, I jokingly warmed Mike to look for the menu specials and to avoid ordering expensive drinks. The warm Ale house atmosphere, together with the hot meals, was a welcome compared to the cold February weather. What was not welcome, though, was the seating arrangement. And the man seated at the bar stool closest to us was carrying on a conversation in a very loud voice with two friends, often dropping an expletive (脏话). Mike and I finally gave up trying to hold a conversation and ate silently, making a mental note that in the future, we would be more careful with the seating we accepted.Mike completed his meal and stepped away from the table. I waited for my check. While I waited, the man opposite me continued to talk loudly. This time, he looked around and saw me seated behind him. Facing me, he said, "I apologize for my language." I smiled and in a friendly voice said, "You have used that word many times since I sat down, and it was impossible not to hear you." We both laughed. The man apologized again, adding that his hearing is damaged so he speaks loudly. He said, "I'm paying for your lunch," I smiled, telling him it was not necessary, but he insisted. I said thank you and left the table.I waited for my husband by the entrance. When Mike found me, I told him about the man's kindness. Mike stared at me and said, "It was the one time you were going to pay, and I lost out again."1.（1） What can be inferred about Mike from paragraph 1?A . He got tired of the lifestyle.B .

Confused.3. 阅读理解If you're British or live in a Commonwealth nation, Christmas doesn't end on December 25. The day after Christmas is known as Boxing Day, and the relaxing holiday is a chance to allow thecelebration for one more restful day.But its name has nothing to do with the sport of boxing, and unlike the popular idea, did not appear from a need to return unwanted gifts or clean up trash produced by Christmas gifting.There are several theories as to how that charitable tradition became known as "boxing". Some historians link the use of the term to boxes of donations that were laid in churches during the pre-Christmas season of Advent in the early days of Christianity during the second and third centuries A. D. The day after Christmas, the boxes were opened and the money was given away to the poor.Another possible story for Boxing Day has to do with a tradition that formed in 19th century Victorian England, where servants sacrificed (牺牲) time with their own families to cater to their employers on Christmas. On the day after Christmas, employers would give the servants a rare day off and send them home with leftovers from the family's Christmas feast for their service.Though the reasons are lost to history, Boxing Day charity eventually fell out of tradition---and was replaced with physical and material pleasures. Today, the holiday is linked with sports, with major football rugby, and cricket matches and horse races taking place on December 26.December 26 is also a big shopping day throughout the UK and the Commonwealth. The holiday kicks off what is known as " Boxing Week", during which retailers（零售商）try to move old stock and shoppers compete for one last bargain of the year. In recent years, though, the American tradition of Black Friday---massive sales that take place the day after Thanksgiving each November---has become popular in the United Kingdom and has largely overshadowed Boxing Week.1.（1） What kind of festival was Boxing Day probably in thebeginning?A . A charitable festival.B . A religious festival.C . A sports festival.D . A business festival.2.（2） What does the underlined part "cater to" in paragraph4 probably mean?A . Take care of.B . Depend on.C . Put up with.D . Pick up.3.（3） How is Boxing Week going in the United Kingdomrecently?A . It has become an online shopping day.B . It has been replaced by Black Friday.C . It only covers popular sports events.D . It has become less important than before.4.（4） What is the best title for the text?A . When Did Boxing Day Come into Being?B . Why Did People Celebrate Boxing Day?C . How Is Black FridayCelebrated in the UK? D . Why Is Black Friday Popular in the UK?4. 阅读理解The debate over washing dishes by hand and using a dishwasher has been on TreeHugger since it faced the world. In the earliest article I could find from 2005, the dishwasher came out the clear winner, with researchers from the University of Bonn saying it uses only half the energy and one-sixth the water.Fifteen years later, we're still talking about it, and a new study published in the journal Environment Research Communications shows not much has changed. Dishwashers still take the prize for efficiency (效率), both in terms of energy and water used. The findings are interesting because kitchen cleanup is something we do every day, so why not learn the best way?Forty participants were required first to load and run a dishwasher and then to wash dishes by hand the way they would at home. They answered survey questions afterwards about their dish washing behaviors. Three other participants were then required to load a dishwasher and wash dishes by hand following best practices. This meant not pre-rinsing (预冲洗) dishes before loading them in the dishwasher and using therecommended normal cycle with heated dry, rinse-aid, and high-quality cleaner. For washing dishes by hand, this meant using the two-basin method "where dishes are soaked (浸泡) in hot water, rinsed in cold water, and are air-dried."These "best practices" differ from typical dish washing behaviors. Most people pre-rinse their dishes before loading them into a dishwasher. They also run the tap while washing by hand, which wastes large amounts of water, and rinse with hot water. The researcher found that these typical practices produce "5,620 and 2,090 kg of greenhouse gas emissions (排放) based on washing 4 loads a week for 10 years. "So the dishwasher was less than half as bad as hand-washing, even when improper techniques were used.When it comes to water usage, the benefits of dishwashers continue. Over the course of ten years, a dishwasher will use 16,300 gallons of water, 99.8 percent of which comes from daily use; whereas, washing the same number of dishes by hand for ten years will use 34,200 gallons.1.（1） What did people think of the dishwasher fifteen yearsago?A . It was expensive.B . It was effective.C . It was of little use.D . It was harmful.2.（2） What were the forty participants asked to do duringthe experiment?A . To wash dishes as they usually do.B . To wash all the dishes without soaking.C . To use the two-basin method for a week.D . To ask questions about doing housework.3.（3） What is the typical way of washing dishes with adishwasher?A . Tuning of the water tap during the process.B . Soaking the dishes in hot water first.C . Washing dishes four times a week.D . Rinsing the dishes before loading them.4.（4） How much water can be saved with a dishwasherover ten years?A . About 5,500 gallons.B . About 16,000 gallons.C . About 18,000 gallons.D . About 34,000 gallons.二、任务型阅读5. 任务型阅读Good social skills are an important part of building rich friendships, enjoying yourself in public, and succeeding in your career.

2020-2021学年深圳高级中学高三英语下学期期中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AChina has 410K5Gbase stationsChina built 257,000 new 5G base stations in the first half of the year, according to the Ministry of Industry and Information Technology (MIIT).Shipments of 5G phones reached 8623 million unis in China, with 5G package users hitting 66 million by the end of June, said Wen Ku, head of information and communication at the ministry.To give full play to the commercialization of 5G, more policies should be implemented to boost the vitality of the market, Wen said, adding that international cooperation in 5G technology, industry and application should be strengthened.AG600 seaplane’s test flightKunlong, China’s homegrown AG600 large amphibious aircraft, conducted its first sea-based test flight on Sunday morning, marking a new milestone in the program.The AG600 is China’s second amphibious aircraft, after the SH-5, which was developed in the 1970s for military purposes and has been retired for a long time.These specifications make it the world’s biggest amphibious aircraft, surpassing Japan’s ShinMaywa US-2 and Russia’s Beriev Be-200.Once in service, it will put an end to the absence of a large rescue aircraft in China and will be very useful in the national emergency rescue and disaster relief systems.Beidou products land abroadAccording to Ran Chengqi, director general of China Satellite Navigation Office, Beidou has been constantly deepening its compatibility, interoperability and cooperation with the US’ GPS, Russia’s GLONASS and the EU’s Galileo. It has also entered international organizations of civil aviation, maritime affairs, search and rescue satellites and mobile communication.BDS-based services have been successfully applied in land mapping, precision farming, digital development and smart port construction in member countries of ASEAN, South Asia, Eastern Europe, West Asia and Africa.1. What can we learn from this passage?A. The total number of 5G phones has reached a new level.B. Kunlong, unlike SH-5, is not just for military purposes.C. Technologies mentioned above need more cooperation with others.D. BDS-based services have been provided for users in many countries.2. Which of the following is most probably related to agriculture?A. 5G phonesB. BDS-based servicesC. AG600 seaplaneD. Beriev Be-2003. If your friend did a course in marketing management, he may choose a job in a ________.A. 5G technology related marketB. large amphibious aircraftC. BDS-based projectD. China Satellite Navigation OfficeBHidden beneath the surface in the roots of Earths astonishing and diverse plant life, there exists a biological superhighway linking together the members of the plant kingdom in what researchers call the "wood wide web".The network is comprised of thin threads of fungus (真菌) that grow outwards underground up to a few meters from its partnering plant, meaning that all of the plant life within a region likely connected to one another. The partnership is beneficial for both parties involved, plants provide carbohydrates (碳水化合物) to the funguses and in exchange, the funguses aid in gathering water and providing nutrients to its partnering plant.A study conducted by Rensen Zeng of theSouthChinaAgriculturalUniversityfound that this also allowed for plants to warn one another of potential harm. The study showed Broad Beans used the fungal network to spy on one another for upcoming danger.Like our Internet, this fungal connectivity is also full of crime. Some plants, such as Golden Marigolds have been found to release poisons into the network to slow down the growth of surrounding plants in the fight for water and light. Other plants, such as the Phantom Orchid, do not have the chlorophyll (叶绿素) and must get the necessary nutrients from surrounding plants.Research suggests that animals such as insects and worms may be able to detect slight exchanges of nutrients through the network, allowing them to more easily find delicious roots to feed on; however, this has not been conclusively made clear in experimentation. The more we learn about this phenomenon, the more our understanding of the plant life of our planet will continue to change. Perhaps one day, we may be able to map out these complex networks entirely.4. What is the function of the first paragraph?A.To explain the aim of the web.B. To introduce the main topic.C. To give definition of diverse life.D. To show the importance of plants.5. The criminal behavior of plants can be seen as a way to________.A. compete for survivalB. gather more waterC. take in sunlightD. break natural rules6. What does the last paragraph suggest?A. Animals can also feed on the fungus.B. Nutrient exchanges are too slight to detect.C. No experiment can prove the phenomenon.D. More needs to be done to work out the network.7. Which can be the best title for the text?A. The Partnership between PlantsB. The Unknown Roots of the EarthC. The Superhighway Linking the PlantsD. The Mysterious Map Changing the WorldCJohn Montefiore's path to graduation from theUniversityofTorontowas a little unusual. He recently completed his bachelor's degree(学士学位) which he started in1995.Montefiore left university in 1996 and tried to tell himself that a degree wasn't necessary for personal success. But it remained unfinished businessuntil he made the decision to return in 2018 at the age 42. At that time, his job development stalled, so he made up his mind to go back to school in order to improve himself and work well in future.The second time around, Montefiore never missed a class and always sat in the front row. He found many courses invaluable and he received the Award of Excellence twice. He found support services played an important role in his successful return. He said, “I hadn't written a paper for years, so I found the college writing centre to be of great use. Before I handed in a paper, they would give me feedback, which was really great. The university hasso much built in to help students succeed and I'm so thankful for that.” But he also met difficulties this time. As a student much older than others, he found it harder to make friends with classmates.However, no matter what had happened before, he finally got his bachelor's degree. He said, “After all these years, I had thought it wouldn't mean anything, but it means a lot. I totally understand the value of education now. It's not necessarily the value that other people see in it, but the value it gives me as a person, for my confidence and my self-esteem. It also helps me prepare well before I re-enter the workplace.”8. Why was Montefiore's graduation unusual?A. He had achieved personal success before.B. He understood the importance of a degree.C. He finished his degree at a much older age.D. He began his university study at a young age.9. What does the underlined word "stalled" in paragraph 2 probably mean?A. Stopped.B. Started.C. Survived.D. Succeeded.10. What can we learn about Montefiore from the third paragraph?A. He got good grades very easily.B. He took his study seriously this timeC. He was thankful for his classmates' helpD. He had difficulty using support services.11. What did Montefiore learn from his experience?A. Confidence is important in one's life.B. Others' opinions on education matter a lot.C. Higher education is a must for personal success.D. Education makes one feel better about himself.DWe all use different ways to remember ideas, facts and things we need to store. Remembering is an extremely important part of our learning experience. Information process, storage and recall encourage purposeful learning.But the brain doesn’t store everything we want or need for future use. It makes choices and tends to remember information that forms a memorable pattern. Things you learned recently can be particularly difficult to remember because they haven’t taken root in your mind.“Forgetting allows us to remember what is really important to our survival. We forget much of what we read, watch, and think directly every day.” writes John Medina in his book, Brain Rules.How do you avoid losing 90%of what you’ve learned? An inspiring writer and speaker Zig Ziglar once said: “Repetition is the mother of learning, the father of action, which makes it the architect of accomplishment.”Repetition has been a remembering skill for ages. When you hear or read something once，you don’t really learn it-at least not well enough to store the new information for long. The right kind of repetition can do wonders for your memory. People learn or remember better by repeating things or getting exposed to information many times. Othersrepeat particular steps or processes deliberately a number of times or even years to become better at certain skills.Daniel Coyle explains in his book, The Little Book of Talent:“...closing the book and writing a summary, even short ones, forces you to figure out the key points, process and organize those ideas so they make sense, and write them on the page. When you pick it back up weeks later, reread all of your notes or highlights to strengthen the ideas even further.”People learn by repeating things. Better learning is a repetition process. Every time we repetitively access something we already know, we increase the memory’s stored value.12. Which of the following can be inferred from the passage?A. The brain tends to store 90% of the things we learn.B. The fresher the information isthe easier to remember.C. Thinking is more important than remembering in study.D. The brain tends to choose and keep what it thinks important.13. How does the writer prove his opinion?A.By giving examples.B. By listing numbers.C. By borrowing words of experts.D.

Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments couldencourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”4.

All of my hard work paid off. My mom had spent a lot on my attending a private high school, so I made sure to push myself: I volunteered, took part in various clubs, and graduated with honors. I was so excited to start a new part of my life.Soon enough, the big day came, but it wasn't like what I had thought. The first two weeks were the most difficult days of my entire life.

I also found a ton of jobs. In any free time, I started forcing myself to go to the gym. I wanted to keep every part of my day busy so I wouldn’t think about how lonely I felt. Soon after, I began to control my eating, considering it another solution to my homesickness. But soon there was something wrong with me.Finally, I went to see a doctor. When the doctor told me I had no choice but to take time away from school, I started to fear. How could I stop? School was what I was best at. “I’m not so bad,” I thought in my head. But the result was that I was taken to hospital again a month later and my mother camewoefully. I had to take a semester off from school, and go to the treatment center near my home.If there are girls who are suffering similarly, I hope you know that there is hope and that you should have a positive attitude towards life. Though you may feel alone, there are so many people who can understand your struggle. That’s why I want to share my story.12. Why did the author push herself during high school?A.
