辽宁省锦州市黑山县黑山中学2019_2020学年高一物理下学期线上教学检测试题含解析

辽宁省锦州市黑山县黑山中学2019-2020学年高一物理下学期线上教学检测试题（含解析）（考试时间：90分钟）一、选择题（本大题共12小题，每小题4分，共计48分。

其中下1-8题为单项选择，9-12题为多项选择。

选对得4分，选对但不全得2分，有选错的得0分）1.下列关于曲线运动的说法正确的是（）A. 物体所受合外力一定不为零，其大小方向都在不断变化B. 曲线运动一定是变速运动，且速度的大小和方向都在不断变化C. 做曲线运动的物体，其速度方向与加速度方向不在同一条直线上D. 做直线运动的物体，其速度方向与加速度方向不在同一条直线上【答案】C【解析】【详解】A．物体做曲线运动的条件是合力与速度不在同一条直线上，因此合外力不可能为零，但其大小和方向都可以保持不变，即可以为恒力，例如平抛运动，故A错误；B．曲线运动的速度方向必然改变，因此属于变速运动，但大小不一定改变，例如匀速圆周运动，故B错误；C．物体做曲线运动的条件是合力与速度不在同一条直线上，根据牛顿第二定律可知加速度方向与合外力方向相同，即其速度方向与加速度方向不在同一条直线上，故C正确；D．如果速度方向与加速度方向不在同一条直线上，那么物体将做曲线运动，故D错误。

故选C。

2.铁路在弯道处的内外轨道高度是不同的，已知内外轨道平面对水平面倾角为θ，如图所示，弯道处的圆弧半径为R，若质量为m的火车转弯时速度大于tangRθ，则（）A. 内轨对内侧车轮轮缘有挤压B. 外轨对外侧车轮轮缘有挤压C. 内轨和外轨对车轮边缘均不挤压D. 这时铁轨对火车的支持力等于cos mgθ【答案】B 【解析】【详解】ABC ．假设火车以某一速度v 通过弯道，内外轨道均不受侧压力作用，其所受的重力和支持力的合力提供向心力，由图可得tan F mg θ=合合外力等于向心力，因此又有2tan v mg m Rθ=解得v =即当v =>v 时，重力和支持力的合力不够提供向心力，则火车拐弯会挤压外轨，故AC 错误，B 正确； D ．当内外轨没有挤压力时，受重力和支持力，此时cos mgN θ=由于外轨对火车的作用力沿轨道平面，可以把这个力分解为水平和竖直向下两个分力，由于竖直向下的分力的作用，使支持力变大，即此时铁轨的对火车的支持力大于cos mgθ，故D 错误。

ABeijing, with co-host Zhangjiakou in Hebei Province, will hold the 2022 Winter Olympics. That will benefit the capital as well as its residents, so the below are something to be expected from the Winter Olympic Games.Blue SkiesIt is highly expected that hosting the Winter Olympic Games will push Beijing to reduce pollution and improve the air quality more effectively.Beijing began carrying out a five-year plan from 2013 that cost 130 billion US dollars to upgrade heating systems, cut car emissions and close heavy-polluting plants. Such efforts will not only be made in Beijing but in neighboring Hebei and Tianjin as well.TransportationAlthough Beijing is the host city of the 2022 Winter Olympic Games, Chongli county of Zhangjiakou in Hebei will host some of the snow events.The capital region is likely to benefit from investments in infrastructure (基础设施), including the Beijing-Zhangjiakou intercity (城市间的) railways, expansion of Beijing subway systems, upgraded highway networks and another regional airport.Winter SportsBeijing's vision is to develop a winter sports market for more than 300 million people in northern China.China plans to reuse 11 of 12 venues (场馆) built for the 2008 Olympics and only needs to build a new rink for speed skating, effectively easing possibleTransformationOn the back of the Winter Olympics, the Beijing government is looking at hopeful sports-related industry as a new growth driver to power its economy.The goal is to integrate (结合) the Winter Olympic Games with sustainable (可持续的) development plans for the wider region, focusing on clean energy, green technology, and improvement in ecology and air quality.TourismThe country's plans to develop a winter sports industry will improve Zhangjiakou’s reputation as a tourist destination by upgrading its transportation system and facilities, such as hotels and restaurants.21. What can be a suitable title for the text?A. How Important the 2022 Winter Olympics is.B. What Have Been Done for the 2022 Winter Olympics.C. When and Where to Hold the 2022 Winter Olympics.D. What to Be Expected from the 2022 Winter Olympics.22.What does the underlined word “idle”probably mean in the text?A. LazyB. Not in use.C. Not seriousD. Not working hard.23. Which is NOT the benefit of hosting the 2022 Winter Olympic Games?A. Air quality will be improved.B. Transportation will be more convenient.C. Winter sports will be popular across China.D. The winter sports industry will help attract tourists.24. “By 2025, around 600,000 new jobs will appear.” can be an example for _____.A. TransportationB. Winter sportsC. TransformationD. TourismBI had an old neighbor， a doctor named Gibbs． When Doctor Gibbs wasn't saving lives， he was planting trees．He had some interesting theories about planting trees． He hardly watered his new trees．Once I asked why and he told me that watering plants damaged them because it made them grow weaker． He said he had to make things difficult for the trees so that only the strongest could survive． He talked about how watering trees made them develop shallow roots and how， if they were not watered， trees would grow deep roots in search of water．So， instead of watering his trees every morning， he'd beat them with a rolled up newspaper． I asked him why he did that， and he said it was to get the trees' attention．Doctor Gibbs died a couple of years after I left home． Sometimes I walked by his house and looked at the trees I'd watched him plant 25years ago． They were tall and strong．I planted several trees myself a few years ago． Two years of caring for these trees meant they grew up weakly．Whenever a cold wind blew，my treesease never could．Every night before I go to bed，I check on my two sons．I often pray that their lives will be easy．But lately I've been thinking that it's time to change my prayer．I know my children are going to experience difficulties．There's always a cold wind blowing somewhere．What we need to do is to pray for deep roots， sowhen the rains fall and the winds blow， we won't be torn apart．25. How did the author feel about Doctor Gibbs's planting trees at first？A. Great．B. ImpracticalC. shockedD. Puzzled26. What did Doctor Gibbs do to the trees he planted？ ______A. He let them grow quickly．B. He beat them to get their attention．C. He helped them search for water．D. He read a newspaper near them．27. What does the word "Adversity" in paragraph 5 mean？ ______A. Bad weather．B. A shortage of water．C. Enough care or attention．D. Difficult living conditions．28. What does the author learn from Doctor Gibbs？A. Elders are treasures．B. Two heads are better than one．C. No pain， no gain．D. Only those who bear the most become the highest.CWould you like to be a king or queen? To have people waiting on you hand and foot? Many Americans experience this royal (王室的)treatment every day. How? By being customers (顾客)，The American idea of customer service is to make each customer the center of attention. Need proof? Just listen to the advertisements. Most of them sound like the M cDonald‘s ad: We do it all for you.” Actually, not all stores in America roll out the red carpet (地毯)for their customers. But wherever you go，good customer service means making customers feel special.People going shopping in America can expect to be treated with respect from the very beginning. Most places don’t have a“furniture street”or a“computer road” which allow you to compare prices easily. Instead, people often use thetelephone and “let their fingers do the walking” through the Yellow Pages. FromThe Contact for the first time can help them decide where to shop.When customers get to the store, they are treated as honored guests. Customers don‘t usually find store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and offer to help them find what they want. In most stores, the signs that label each department make shopping very easy. Customers usually don’t have to ask how much items cost, since prices are clearly marked. And unless they’re at a flea market (跳蚤市场)or a yard sale，they don’t bother trying to bargain (讨价还价).When customers are ready to check out，they find the nearest and shortest checkout way. Good stores open new checkout ways when the ways get too long. Some even offer express ways for customers with 10 items or less. After they pay for their purchases，customers receive a smile and a warm“thank you”from the clerk. Many stores even allow customers to take their shopping bags out to the parking place. That way, they don't have to carry heavy bags out to the car.29. We can learn from the first paragraph that customers in America ________ .A. are kings or queens from different countriesB. are the God in the customer serviceC. are served with red carpet everywhereD. are treated in different ways30. The underlined word“courteous”in Paragraph 2 is closest in meaning to “________”A. VariousB. loyalC. specialD. polite第二节：阅读七选五（共5小题：每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

AWe work with Cambridge County Council’s Participation Team to create opportunities for young people to visit the University and learn more about it. The following events are scheduled for the 2019/2020 academic year.SuperStar workshops12 engaging workshops are planned for young people aged 7 to 11. These half-day visits will be held throughout the year, at times when young people are not at school. If participants complete 8 of the 12 workshops, they will be awarded the nationally recognised SuperStar Crest Award.Please note, workshops will only run if we have a sufficient number of attendees (usually around 3+ participants).Explore University DaysExplore University Days are for young people aged 12-15. Participants visit the University for two days and engage with a range of university-related workshops, and other fun activities.Previous participants have engaged with the following:◆Visited the Sports Centre◆Took part in a Neuroscience workshop◆Enjoyed a two-course meal at a University CollegeDates will be confirmed in early December 2019, and a schedule for event will follow in the New Year.Events for post-16 studentsIf you are studying for your post-16 qualifications and are considering applying for Cambridge or would like to find out more about a specific subject, the following events might be for you:◆University and College Open Days◆Subject Masterclasses◆Cambridge Science Festival1. What can the participants do in SuperStar workshops?A. To stay only half a day.B. To get a gift.C. To enjoy a free meal.D. To visit all the 12 workshops.2. Which event is specially for applicants of Cambridge?A. SuperStar workshops.B. Events for post-16 students.C. Explore University Days.D. The Neuroscience workshop.3. The events in the passage most probably aim to .A. introduce some coursesB. advertise Cambridge UniversityC. en rich students’ spare time lifeD. promote children’s interest in touringBWalk around the city of Ann Arbor, Michigan, and you may see a green animal named Sluggo and a flying pig named Philomena.You might even see street artist David Zinn drawing them using only sidewalk chalk and charcoal (炭笔)．At the age of 12, David began working as an artist.His dad was writing a computer instruction and worried that it would be boring to read.So he asked David to draw pictures of turtles (the name of the computer program) to explain it.The publisher liked his drawings, and soon David had the job of drawing more turtles in action.“I learned a great lesson, which was that, to make money as an artist, I couldn’t always draw what I wanted，” he says.“I had to f igure out how to draw a turtle drinking tea and other things like that.”David worked for 20 years as a commercial (商业的) artist, but he often felt cooped up (禁锢) sitting at a computer for 10 hours a day.Then, on a sunny afternoon about ten years ago, he br ought some chalk and started drawing on the sidewalk.That’s when Sluggo came to life.“One of the reasons I like to put art on the street is to take people by surprise，” he says.“I can have fun drawing, and knowing it will be washed away helps me not think too much.It frees me up.”It takes David about two hours to complete one drawing.He uses a lot of sidewalk characteristics in his street art.It can be difficult to draw on surfaces that are not flat.He has tonotice where shadows will land so they won’t d estroy the 3D drawings he creates.Today, more and more people are accepting and looking for his work.David’s artwork can also be found across the country and even throughout the world.Photos of his drawings have been shown at many universities and museums.4. What did David learn from drawing turtles for his father?A．Work hard.B．Follow your heart.C．Draw what you like. D．Draw in a creative way.5．How does David feel when knowing his drawing will be washed away?A．Relaxed. B．Worried.C．Unhappy. D．Surprised.6．In what way is David’s art special?A．It shows his real life.B．It is drawn on the flat sidewalk.C．It needs a very long time to finish a drawing.D．It is 3D street art created by simple painting tools.7．What do we know about David’s drawings?A．They are becoming popular.B．They are too difficult to understand.C．They are found mainly at museums.D．They are hardly accepted by adults.CHow many sports stars can you name? Whether it’s ten or thirty, I believe that 90% of them would be male (男性). Even in today’s society, which calls for gender equality (男女平等), it seems that female sports stars simply don’t get the same coverage (报道) as male players.The World Cup is the most widely followed sporting event in the world. According to a report, almost 715 million people watched the final match of the 2006 FIFA World Cup, a ninth of the whole population of the planet. But how many people notice the fact that the FIFA Women’s World Cup has just taken place in Canada? The US team was the winner, after beating the Japanese team 5-2 in the final match. England even got a third place! However, the England team in the men’s World Cup seldom runs to the quarterfinals. While the World Cup enjoys primetime on most BBC channels, the FIFA Women’s World Cup is put aside. The only time the media (媒体) made the news was when an English player scored an own goal!The inequality doesn’t end with football. Just recently, Caroline Wozniacki (a top Danish tennis player) complained that women don’t get the same chance as men to play on the show courts at Wimbledon. In this case, I think it’s the luck of the draw — the further you get in the competition, the more likely you are to play on the show courts. In the opening stages, it is true that often only the best players w ill play their matches on the show courts. Women’s tennis does get lots of coverage, though many complain that it isn’t exciting to watch.Many people think the women’s sport is often paid less attention to, but I think this is slowly starting to change. In the UK, there is a campaign called This Girl Can, which aims to get girls and women back into sports, regardless of their ages, shapes or sporting abilities. Hopefully this campaign will encourage more people to take up and enjoy sports, and help to redu ce the nation’s health problems.8．The hidden message in Paragraph 1 is that ________.A．female players don’t get much attentionB．male players are more likely to enjoy sportsC．there are more male players than female playersD．the media prefer to provide coverage of female sports9．The author thinks Caroline’s case ________.A．is due to the level of players’ abilityB．is another example of gender inequalityC．helps women’s tennis get a lot of coverageD．leads to disappointment at women’s tennis10．What’s the author’s attitude toward the fixture of women’s sport?A．Negative. B．Positive.C．Unconcemed. D．Doubtful.11．Why does the author expect more women to take part in sports?A．To beat male players.B．To have a household name.C．To achieve their dreams.D．To improve their health.DThe sun rises above the Arctic Ocean (北冰洋). Across the frozen sea, a white bear moves slowly.The bear stops and sways (摇晃) his head from side to side. There is nothing to see but endless ice and red sky. Then his powerful nose senses what his eyes cannot: a beluga whale is nearby.The bear follows the smell and spots a large hole in the ice where a small white whale is swimming. He silently walks toward the hole, then stops, standing still. The whale does not see the bear, whose white fur makes him appear invisible (看不见的) against the ice.Finally, the whale swims close to where the bear is waiting. With terrifying speed, the bear comes to life and moves toward the whale. In a moment it is over, and the bear eats his first meal in nearly a week.Polar bears rule the frozen sea, but their ancestors weren’t always built for ice and snow. The first Arctic bears were brown bears, a species that includes grizzly bears. They came to the icy north over a hundred thousand years ago.No one knows for sure why these bears traveled to such a cold place. Scientists think they might have wandered north looking for food. Maybe they became trapped by glaciers and couldn’t leave. Whatever the reason, the bears never should have survived.But they did. They got used to their new environment. Their bodies changed. Their behavior changed, too. Eventually, the bears developed into an entirely new species: the polar bear. You can see some of the characteristics that polar bears developed to survive.Sadly, these characteristics may now threaten the polar bear’s survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上). They are poor hunters on land, which means they often go a long time between meals. The polar bear, king of the Arctic, is now classified as a threatened species.Although the future of the polar bear is unknown, the tale of two bears continues. As temperatures rise, grizzly bears have been spotted moving north into polar bear territory (领地). These long-lost cousins, once forced apart by nature, are coming back together again.12．What can be inferred about the white bear mentioned in the first four paragraphs?A．It is noisy. B．It is smelly.C．It is starving. D．It has good eyesight.13．What do we know about polar bears’ ancestors?A．They were a darker-colored species.B．They were born to live in ice and snow.C．They had no trouble getting used to the icy north.D．They came to the Arctic Ocean about 1,000 years ago.14．Why are polar bears struggling to survive?A．They are losing their hunting ground.B．They are threatened by other animals.C．They are spending little time on land.D．They have difficulty reaching the shore.15．Which of the following can be the best title for the text?A．The climate changeB．The polar bear’s favorite mealC．The dark past of the polar bearD．The mysteries of the Arctic Ocean第二节(共5小题；每小题2.5分，满分12.5分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

In the study, the participants were asked how often they ate six different types of mushrooms: oyster, shiitake, white button, dried, golden and tinned. The findings showed that eating more than two shares of mushrooms per week somehow lowered the chances of mild cognitive impairment (MCi) by 50% against those who ate fewer than one share.MCI is a condition that can make people forgetful, affect their memory and cause problems with language, attention and finding the exact position of objects in space. Changes in behavior can be not very noticeable and not serious enough to be known as dementia (痴呆).Participants who ate more mushrooms were found to perform better in thinking and processing exams and also exhibited a faster processing speed. The advantage was reportedly more apparent in those who ate more than two shares a week or more than 300 grams.The scientists pointed out, however, that they have yet to put up a direct link between the fungi and brain function.The researchers also acknowledged that since this study mainly relied on self-reported information on mushroom intake and other dietary factors (因素), further studies may be required.Still, the lead study author Lei Feng is encouraged by their findings.“This correlation is surprising and encouraging,” Lei said.Mushrooms are one of the richest dietary sources of ergothioneine — a matterwhich humans can’t make on our own.4．What are the findings in paragraph 3 about?A．Diets and lifestyles. B．The percent of MCI.C．The types of mushrooms. D．The benefit of eating mushrooms.5．What can we know about MCI?A．It can strengthen memory. B．It can result in language problems.C．It can make people get lost. D．It can lessen the chance of forgetfulness.6．What is the result if students often eat more mushrooms?A．They will take the exams much more easilyB．Their academic performance improves greatlyC．Their thinking ability is better than the majorityD．They will love communicating with others.7．Where does the text most probably appear?A．Scientific fiction. B．An advertisement.C．A science report. D．Adult literature.CPinocchio may be just a children's fairy tale, but Spanish scientists at the University of Granada recently investigated the so-called ''Pinocchio effect'' and found that our noses don't grow when we tell a lie, but actually shrink a bit.Dr. Emilio Gómez Milán and his team developed a lie detector test that used thermography to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tips of their noses dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientists also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.''One has to think in order to lie, which rises the temperature of the forehead, '' Dr. Gomez Milan explained the findings. ''At the same time we feel anxious, which lowers the temperature of the nose. ''For this study, researchers asked a number of 60 students to perform various tasks while being scanned by thermal imaging technology. One of these tasks involved calling a 3 to 4 minutes call to their parents, partner or a friend and telling a significant lie. Participants had to devise the lie by themselves during the call, and the thermal cameras picked up this ''reverse Pinocchio effect'' caused by the fluctuation (起伏) in temperature in the nose and forehead.Interestingly, the thermal lie doctor picked up the temperature difference in 80 percent of test subjects, which is a better rate of success than that of any modern lie doctor.''With this method we have achieved to increase accuracy and reduce the occurrence of 'false positives', something that is frequently with other methods such as the polygraph (测谎仪) , '' said Dr. Emilio Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.The thermal lie doctor has been the most reliable in the world, 10% more than the popular polygraph.8．Why does the author mention ''Pinocchio'' at the beginning?A．To tell a fairy story B．To warn us not to lie.C．To introduce a research. D．To inspire us to doubt old beliefs.9．According to the research, what might happen if you tell a lie?A．Your nose gets longer.B．Your nose becomes smaller.C．Your temperature gets higher.D．Your temperature remains stable.10．What can we learn about the research?A．Researchers conduct the study by interviewing.B．Researchers design difference lies for participants.C．The thermal lie detector will prove a popular one.D．The thermal lie doctor may assist law enforcement.11．Which might be the best title for the passage?A．Will lie detectors tell the truth?B．Will lying make your nose longer?C．Will lying make your temperature rise?D．Will thermal imaging technology be reliable?DIt was back in 2014. I learned I needed an operation to remove the tumor (肿瘤). Hearing the word “cancer” was the first shock, but knowing the surge on would have to cut the front of my neck open was a lot to swallow. I was relieved to learn that thyroid (甲状腺) cancer can be treated if caught early, but 1 wasn’t thrilled it would mean a lifelong scar front and center on my neck.Back at home, I looked at my reflection in the mirror. I admired my neck, running my finger across a delicate gold chain I wore. Then came a tiny voice, “Mommy!” My then five year -old son. Jack, appeared in the mirror behind me. Our reflection was a big reality check. See, my so n didn’t know I had been diagnosed (诊断) with the Big C, or that I was having an operation. I patiently explained my condition to him and told him I would have a scar on my neck after the operation.I never had any intentions of hiding the scar. I didn’t wa nt my son to think my scar was something to be ashamed of. I was his role model and I needed to set a good example. Bad things can happen, but it’s how you deal with them that matters.The operation was successful. The recovery process, bearing it all, in the grocery store, out to dinner with family and on the summer camp pickup line, made me realize, if I could get through this phase (阶段),I could bear the scar of survival forever. The scar proves I looked at fear in the face and won.People will ask about my scar even though it’s a very thin dull line five years later. That means I have the chance to educate others about thyroid cancer and how they should self-check their necks and remind their doctors to do the same, at yearly physicals. To me, the scar is like a superhero stamp.12．What’s the author worried about before the operation?A．Her neck would look ugly. B．The tumor couldn’t be removed.C．Jack couldn’t take care of himself.D．She would have difficulty swallowing.13．Why did the author decide to face the reality bravely?A．She didn’t care how people liked her.B．She realized she didn’t have other choice.C．She wanted to set a good example to her son.D．She felt lucky to have her cancer caught early.14．How does the recovery process turn out?A．Regretful. B．Stressful.C．Surprising. D．Meaningful.15．What can be inferred about the author from the last paragraph?A．She has a better chance of education.B．She feels proud of what she has done.C．She has become an expert in cancer treatment.D．She has suffered from poor health for five years.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。

I slowly got up, looking around to see if anyone was hurt. However, one person did it faster than me. It was my father. He rushed to us, asking us, "Is everyone OK?" His voice was full of anxiety and love. Luckily, all were safe, except my little sister who had her left knee injured. We all surrounded her to check whether she could walk normally. She tried to stand up but failed because of the ache.Paragraph 2：When we had no idea what to do, the strange man came back. He said that the moment he heard the loud sound, he returned immediately. Seeing what we had experienced, he said sorry to us again and again, and told us the dangerous situation could be the reason why the area was closed off by a fence. We had to give up our plan. With his help, we made a little "bed" with the branches, and carried my little sister back finally. What an adventure.写作评分原则及各档次给分范围和要求：1.评分原则附：就考试而言，从考前、考中二个阶段来谈谈学生正确心态的培养。
