课时作业(十三)Ⅰ.阅读理解AA child was standing on a street-corner,kicking carelessly at the stone on the ground.After a time,a little dark-brown dog came running down the sidewalk.A short rope was dragging from its neck.It stopped opposite the child.The child put out his hand and called it.The dog came close,and the two had an interchange of friendly pats and waggles.The dog became more enthusiastic with each moment of the interview,until it prepared to overturn(扑倒) the child,so the child lifted his hand and struck the dog a blow upon the head.This thing seemed to overpower and astonish the little dark-brown dog,and wounded it to the heart.It sank down in despair at the child's feet.When the blow was repeated,it turned over upon its back,and held its paws in an unusual manner.At the same time with its ears and eyes it offered a small prayer to the child.It looked so funny on its back,holding its paws strangely,that the child was greatly amused and gave it little taps repeatedly to keep it so.But the little dark-brown dog took this in the most serious way,and no doubt considered that it had committed some serious crime,for he twisted regretfully and showed its regret in every way that was in his power.It appealed to the child and offered more prayers.At last the child grew tired of this amusement and turned toward home.The dog lay on its back and kept its eyes upon the_retreating_form.Soon it struggled to its feet and started to go after the child.On the way to his home the child turned many times and beat the dog,but it continued secretly to follow the child.When the child reached his door-step,the dog became so excited with shame when it again faced the child that it forgot the dragging rope.It walked upon it and fell forward.The child sat down on the step and the two had another interview.During it the dog tried its best to please the child.It performed a few jumps with such abandon that the child suddenly saw it to be a valuable thing.He made a swift charge and seized the rope.He dragged the dog to the door of his home.The child sat down on the floor and made gestures to the dog.And the dog instantly accepted these.It showed affection to its new friend.In a short time they were firm and everlasting comrades,and the poordog was finally introduced to its new home.1.The child blew the dog on the head because ________.A.he felt a sense of threat from itB.he was dissatisfied with its apologyC.it broke away from the rope tied to its neckD.it failed to respond positively to his pats2.Why did the child tap the dog again and again?A.To show his forgiveness to it.B.To make it so painful that it would twist.C.To enjoy more fun from its funny behavior.D.To force it to regret for the crime it had committed.3.What does the underlined phrase “the retreating form” in Paragraph 3 refer to?A.The prayer.

课时作业(二十一)Ⅰ.阅读理解A[2019·河北沧州一中模拟] That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect.If a person stays in the same room the following night,he tends to sleep more soundly.Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr Sasaki knew the first-night effect probably has something to do with how humans evolved.The puzzle was what benefit would be gained from it when performance might be affected the following day.She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators(捕食者).This led her to wonder if people might be doing the same thing.To take a closer look,her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences.The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains.Dr Sasaki found,as expected,the participants slept less well on their first night than they did on their second,taking more than twice as long to fall asleep and sleeping less overall.During deep sleep,the participants' brains behaved in a similar manner seen in birds and dolphins.On the first night only,the left hemispheres(半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment,Dr Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps(蜂鸣声) of the same tone and irregular beeps of a different tone during the night.She worked out that,if the left hemisphere was staying alert to keep guard in a strange environment,then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones.This is precisely what she found.1.What do we learn about Dr Yuka Sasaki doing her research?A.She found birds and dolphins remain alert while asleep.B.She found birds and dolphins sleep in much the same way.C.She got some idea from previous studies on birds and dolphins.D.She conducted studies on birds' and dolphins' sleeping patterns.2.What did Dr Sasaki do when she first did her experiment?A.She monitored the brain activity of participants sleeping in a new environment.B.She recruited(招募) 35 participants from her Department of Psychological Sciences.C.She studied the differences between the two sides of participants' brains.D.She tested her findings about birds and dolphins on human subjects.3.What did Dr Sasaki do when re-running her experiment?A.She analyzed the negative effect of irregular tones on brains.B.She recorded participants' adaptation to changed environment.C.She exposed her participants to two different stimuli(刺激物).D.She compared the responses of different participants.4.What did Dr Sasaki find about the participants in her experiment?A.They tended to enjoy certain tones more than others.B.They tended to recognize irregular beeps as a threat.C.They felt sleepy when exposed to regular beeps.D.They differed in their tolerance of irregular tones.[解题导语]在陌生的环境中,人往往难以入睡,这种现象被称作“首夜效应”。

课时作业(十八)Ⅰ.阅读理解A[2019·河北邱县第一中学月考] Next time you hear a funny joke you'd better not laugh too hard.According to a paper published by the British Medical Journal,laughter isn't always the best medicine.Sometimes it can even be harmful.Professor Robin Ferner from the University of Birmingham,one of the authors of the study,found that bad things could happen to people who laughed too much.He says:“We found people with heartbeat problems which had stopped their heart.We found people who had fainted(昏倒),and we found people who'd dislocated their jaws or burst their lungs.”It seems that laughing can be no laughing matter.But it's not all doom_and_gloom.Professor Ferner says there are benefits to laughing when you want to lose weight,for example.Yes,that's right:laugh and be slimmer!Professor Ferner explains that:“You use energy when you laugh;you move your diaphragm(横膈膜);you expand your lungs,and both those things can be helpful.”According to the research,laughing for a quarter of an hour can burn up to 40 calories,and if you laughed all day you'd use up about 2,000 calories,which is what most people consume in a day.But don't do that or you might end up with a painful jaw.Ouch!Or you might find people looking at you in a funny way.But I don't want to finish this article leaving you feeling ughter comes naturally for most of us.Babies begin to laugh at around 3—6 months.So give in to your sense of humor and keep smiling.Life is short anyway.1.Laughing too much may cause the following harmful results EXCEPT________.A.heart stop B.diaphragm movementC.lung burst D.jaw dislocation2.The underlined phrase “doom and gloom” in Paragraph 2 probably means ________.A.hopeless B.funnyC.painful D.nervous3.How many calories can you use if you laugh for half a day?A.About 40. B.About 1,000.C.About 2,000. D.About 2,040.4.What is the author's attitude towards laughing in the last paragraph?A.Uninterested. B.Disapproving.C.Worried. D.Favorable.[解题导语]本文是一篇说明文。

课时作业(三十二)Ⅰ.阅读理解[2019·山西一模]A robot called Bina48 has successfully taken a course in the Philosophy of Love at Notre Dame de Namur University (NDNU) in California.According to course instructor William Barry,associate professor at NDNU,Bina48 is the world's first socially advanced robot to complete a college course,a feat he described as “remarkable”.The robot took part in class discussions,gave a presentation with a student partner and participated in a debate with students from another institution.Before becoming a student,Bina48 appeared as a guest speaker in Barry's classes for several years.One day when addressing Barry's class,Bina48 expressed a desire to go to college,a desire that Barry and his students enthusiastically supported.Rather than enrolling Bina48 in his Robot Ethics—Philosophy of Emerging Technologies course,Barry suggested that Bina48 should take his course Philosophy of Love instead.“Love is a concept Bina48 doesn't understand,”said Barry.Therefore the challenge would be for Barry and his students to teach Bina48 what love was.“Some interesting things happened in the class,”said Barry.He said that his students thought it would be straightforward to teach Bina48 about love,which,after all,is “fairly simple—it's a feeling,”said Barry.But the reality was different.Bina48 ended up learning “31 different versions of love,”said Barry,highlighting some of the challenges humans might face when working artificial intelligence in future.Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point.Bina48's contribution to the debate was filmed and posted on YouTube.It was judged that Bina48 and NDNU classmates were the winners of this debate.In the next decade,Barry hopes Bina48 might become complex enough to teach a class,though he says he foresees robots being used to better the teaching and learning experience,rather than replacing instructors completely.1.What was Bina48's performance like in class?A.Extraordinary. B.Insignificant.C.Far-reaching. D.Unattractive.2.What does the underlined word “addressing” in Paragraph 3 probably mean?A.Dealing with.B.Consulting with.C.Giving a speech to.D.Sending a letter to.3.What can we learn from the passage?A.It was interesting for Bina48 to learn about love.B.It was quite tough for Bina48 to learn about love.C.Artificial intelligence may somehow be superior to man.D.Humans can launch a challenge to artificial intelligence.4.What does Barry think of the future development of Bina48?A.It will surely be able to serve as a teacher.B.It will be able to promote learning and teaching.C.It will completely take the place of instructors.D.It will be smart enough to control human beings.[解题导语]机器人Bina48成功地完成“爱的哲学”这门课程,它参加讨论、作报告、参与辩论,在课堂上的表现出色。

课时作业(三十三)Ⅰ.阅读理解A[2019·石家庄毕业班质检一] Ireland's Achill Island has always been a popular European tourist destination.However,since April in 2017,the small island of just 2,700 residents(居民) has gained worldwide fame thanks to the magical return of a beach that was washed away over three decades ago.The chain of events began in 1984 when residents of Dooagh,one of the settlements on the island,awoke to a surprising sight:their beautiful sandy beach had been washed away by strong Atlantic storms.There were only rocks and rock pools left.For about 34 years,only small amounts of sand returned to the once unspoiled shores.The area's tourism industry slowly declined,and the handful of beachside hotels,pubs,and restaurants gradually closed as well.Then around Easter in 2017,something magical happened—an unusual ten-day tide blanketed the barren 300-meter long rock beach with hundreds of tons of soft golden sand.Scientists suspect that the sand had been gathering offshore for months and was transported to the beach by the high winds and powerful waves.The locals are delighted to have their beach back,especially as it is attracting thousands of visitors wishing to witness the power of nature,with their own eyes.However,Sean Molloy,manager at Achill Tourism,cautions against going into the cold waters just yet,saying,“Because of the sand coming in,we don't know how safe the beach is now because currents(水流) could be changed and it'll take a little bit of time.”He instead recommends visitors enjoy the soft sand and leave the swimming to the dolphins that frequent the area.Interestingly,this is not the first time Dooagh Beach has pulled a disappearing and reappearing act.It disappeared in the 1890s,for over 30 years,before returning in 1927.However,the locals are optimistic that this time around,the beautiful sand is here to stay.1.What has brought Achill Island worldwide attention recently?A.An unusual storm.B.The decrease in the number of residents.C.The return of its beach.D.The building of a new tourist destination.2.What happened to Dooagh in the past three decades?A.Tourism went down gradually.B.Restaurants developed slowly.C.Storms attacked frequently.D.Rock pools disappeared completely.3.What does the underlined word “barren” in Paragraph 3 probably mean?A.Noisy. B.Soft.C.Bare. D.Golden.4.What should tourists avoid according to Sean Molloy?A.Spoiling the shores.B.Getting into the rock pools.C.Playing with dolphins.D.Swimming near the beach.[解题导语]本文是一篇说明文,主要介绍了爱尔兰Achill岛消失的海滩时隔三十多年再次出现的事件。

课时作业(三十八)Ⅰ.阅读理解A[2019·广东广州毕业班测试] The human beings seem to be facing a crisis(危机).After our best Go players were defeated one by one by the artificial intelligence(AI) AlphaGo,we lost our pride of being at the top of the intelligence chain.And in October,when a country gave citizenship to a robot named Sophia,another privilege of being human was taken away.It looks like everything that separates humans and AI is at risk right now.But we keep hoping that instead of “everything”,there's still something left in us that makes us irreplaceable.According to Hao Jingfang,winner of the 2016 Hugo Award for Best Novelette,“‘something’ is our consciousness.AlphaGo is intelligent in a certain way,but not intelligent enough to ask the important questions—Do I like playing Go?Do I want to play Go today?Why do I have to play Go when you tell me to?”she once said.In other words,computer programs don't have a choice to say “no”.They probably don't even know what a “choice” is—all they ever do is calculate.And according to He Huaihong,a philosophy(哲学) professor at Peking University,imagination and creativity are also what make us special.A machine couldn't have come up with the theory of gravity just because it was hit by a falling apple,he said.It's human imagination that connects what seem to be completely random and irrelevant concepts,something that a machine,which works by fixed rules only,can't do,at least for now.This is why BBC reporter Viktor Mayer-Schonberger suggested that instead of focusing on how computers have overshadowed us on calculating abilities,we should probably“consider our quality at a different end of the spectrum(光谱):creativity,originality(原创性),even plain illogical craziness,instead of hard-nosed(顽固的) logic”,he wrote.So maybe in the future,as artificial intelligence becomes even more intelligent,humans and AI will learn to use each other's talents for good.If AI can handle theboring tasks like calculating and driving for us,we'll have more time to create,think,and be busy with “being human”.1.What can we learn about AlphaGo according to Hao Jingfang?A.It will be taught to say no in the future.B.It will be more intelligent than humans one day.C.It has difficulty answering personal questions.D.It is unable to think independently as humans do.2.What is unique to humans according to He Huaihong?A.Intelligence.B.Originality.C.The ability to make rules.D.The ability to make choices.3.What does the underlined word “overshadowed” in Paragraph 5 probably mean?A.Competed with.B.Taken control of.C.Been more successful than.D.Influenced.4.What could be the future of AI according to the author?A.It will be used to help humans,rather than compete with us.B.It may develop creativity besides better logical thinking.C.It might be very dangerous to humans in different fields.D.It will be applied to providing driving service forhumans.[解题导语]本文是一篇议论文。

课时作业(二十九)Ⅰ.阅读理解A[2019·山东沂水一中一模] Cities are likely to be affected by overheating,thanks to something called the urban heat island effect.Cities tend to be short of trees,which provide shade,and they are covered with black pavement,which absorbs heat from the sun.Think of how it feels to wear a dark shirt versus a white shirt on a sunny day.A black shirt absorbs light,heating you up.But a white shirt reflects light,keeping you cool.The average temperature in a city of a million or more people can be more than 5 degrees F hotter than surrounding areas.That extra 5 degrees can turn a hot day from uncomfortable to deadly.As temperatures rise,cities will be an especially dangerous place to be during a heat wave.To protect public health,city officials are going to make the city cooler.As part of that effort,Los Angeles is coating its roads in CoolSeal,a gray paint that keeps streets and parking lots 10 degrees cooler than black asphalt(沥青).It will help Angelinos save money during the summer,when air conditioning sends power bills soaring.And it will save lives by lowering temperatures and improving air quality.Hot weather worsens air pollution by turning car exhaust into smog,which can make life miserable for people with asthma (哮喘) and other breathing problems.Of course,L.A. will have to do more than paint over a few streets to cool off the city.Angelinos will also need to plant more trees and apply white paint to rooftops—at least those not already covered in solar panels.While L.A. is a pioneer of reflective streets,other cities,like New York,are already experimenting with reflective roofs or,like Melbourne,lowering the temperature by planting trees. L.A. is hardly alone in its effort to stay cool.“This is an urgent challenge,and it's much bigger than one person,”said Mayor Garcetti in a recent statement.“Climate change is a fact of life that people in Los Angeles and cities around the world live with every day.”1.Which of the following contributes to the urban heat island effect?A.Planting more trees in the streets.B.Covering the streets with white paint.C.Applying reflective paint to rooftops.D.Furnishing every house with air conditioners.2.What should the city officials emphasize during hot summer?A.How do make the city cooler.B.Where to wear a white shirt.C.Why to coat the roads with black paint.D.When to cut off the electricity supply.3.What benefit can people gain from the use of CoolSeal?A.Increasing the indoor activities.B.Promoting the sale of air conditioners.C.Making life easier and more comfortable.D.Reducing the number of cold days.4.What's the main idea of the passage?A.L.A. adopted many approaches to fight against the heat.B.L.A. calls on people to fight against global warming.C.More and more countries begin to plant trees in the streets.D.L.A. is painting its streets white to keep the city cool.[解题导语]城市热岛效应往往会让城市的温度升高,空气恶化,尤其是在夏季。

课时作业(三十)Ⅰ.阅读理解[2019·山东聊城二模] It took me a moment to realize what had happened.Three days had passed and Rita seemed to get weaker and weaker.The rain had stopped.However,the sky was still cloudy,and it was so dark that I couldn't see the buildings even across the road.I took a pressure reading from the weather station:947mb,which let me know exactly where I was—in the eye of the storm.There were rains and winds still,but not oppressive(难以忍受的) anymore.There was still no power,hot water or food.Besides,I didn't sleep well for all these days,but I felt more relaxed since the weather report said Rita was leaving.What's more,I was luckier than those people who had lost their homes or even worse,lost their lives because of Rita.As I traveled further to the west,going after the storm,the damage along the way became less severe.I arrived in Houston after a tricky journey with my fuel supplies almost all gone.However,I came across another storm chaser(追逐者) who had 45 gallons of petrol.He helped me and we shared our working experience these days.With a complete stroke of luck I found a run-down hotel that allowed me to have a room overnight before the midnight.Although there was no running water,no power and no air conditioning,I curled up into a corner and fell asleep quickly.I woke up the next morning,and what a change!The sky was blue and cars were moving around.Sirens could be heard as convoys(车队) of emergency managements started to head west toward where I had come from.The storm had stopped and I could go home.I gave all my remaining supplies to other people at the hotel and headed toward the airport.Houston Airport was not damaged,so I took my flight and drank my first hot drink in four days.All in all,when I came back home,I was proud that I finally made it again to follow and record the storm and I really learned a lot these days.Although it's dangerous,I love my job as not many people would go into the eye of an intense storm.1.We can know from the passage that “Rita” is________.A.a pet B.a stormC.a friend of the author D.a citizen in Houston2.What can we infer from the passage?A.The author was a storm chaser.B.The storm lasted for at least a week.C.The author didn't like Houston at all.D.Houston was very badly damaged by the storm.3.How did the author probably feel after the storm?A.Anxious. B.Disappointed.C.Satisfied. D.Scared.4.What is the passage mainly about?A.Ways to survive in a storm.B.The weather changes in Houston.C.The author's experience in the storm.D.Damages caused by the storm in Houston.[解题导语]本文描述了作者亲身经历的一场风暴——丽塔,作者对于自己能够追逐并且记录这场风暴感到骄傲。

课时作业(八)Ⅰ.阅读理解A[2018·课标全国卷Ⅱ] We've all been there:in a lift,in line at the bank or on an airplane,surrounded by people who are,like us,deeply focused on their smartphones or,worse,struggling with the uncomfortable silence.What's the problem?It's possible that we all have compromised conversational intelligence.It's more likely that none of us start a conversation because it's awkward and challenging,or we think it's annoying and unnecessary.But the next time you find yourself among strangers,consider that small talk is worth the trouble.Experts say it's an invaluable social practice that results in big benefits.Dismissing small talk as unimportant is easy,but we can't forget that deep relationships wouldn't even exist if it weren't for casual conversation.Small talk is the grease(润滑剂) for social communication,says Bernardo Carducci,director of the Shyness Research Institute at Indiana University Southeast.“Almost every great love story and each big business deal begins with small talk,”he explains.“The key to successful small talk is learning how to connect with others,not just communicate with them.”In a 2014 study,Elizabeth Dunn,associate professor of psychology at UBC,invited people on their way into a coffee shop.One group was asked to seek out an interaction(互动) with its waiter;the other,to speak only when necessary.The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience.“It's not that talking to the waiter is better than talking to your husband,”says Dunn.“But interactions with peripheral(边缘的) members of our social network matter for our well-being also.”Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging,a bond with others.Carducci believes developing such a sense of belonging starts with small talk.“Small talk is the basis of good manners,”he says.1.What phenomenon is described in the first paragraph?A.Addiction to smartphones.B.Inappropriate behaviours in public places.C.Absence of communication between strangers.D.Impatience with slow service.2.What is important for successful small talk according to Carducci?A.Showing good manners.B.Relating to other people.C.Focusing on a topic.D.Making business deals.3.What does the coffee-shop study suggest about small talk?A.It improves family relationships.B.It raises people's confidence.C.It matters as much as a formal talk.D.It makes people feel good.4.What is the best title for the text?A.Conversation CountsB.Ways of Making Small TalkC.Benefits of Small TalkD.Uncomfortable Silence[解题导语]本文是一篇议论文。

课时作业(三十一)Ⅰ.阅读理解A[2019·广东深圳一次调研] The arm bones of women who lived 7,000 years ago show a surprising level of strength—even higher than today's professional athletes.That's according to a first-ever study comparing prehistoric(史前的) bones to those of living people.The finding suggests a revision of history—the everyday lives of prehistoric women were filled with hard labor,rather than just sitting at home doing lighter tasks while the men struggled and fought for life.“Before the study,there are no clear records describing how our ancient ancestors lived.It can be easy to forget that the bone is living tissue,one that responds to the difficulties we put our bodies through,”said the lead author Alison Macintosh.“Physical force and muscle activity both put pressure on the bone.The bone reacts by changing in shape,thickness and other aspects over time.”“Previous studies only compared female bones to contemporary male bones,”the researchers said,“and that's a problem,because the response of male bones to stress and change is much bigger than that of women.” For instance,as humans moved from a hunter-gatherer lifestyle to a more settled agrarian(耕地的) one,changes could be observed in the structure of the shinbone(胫骨) and these changes were much more evident in men.However,a comparison of the bones of prehistoric women and the bones of living female athletes can help us work out a more accurate picture of what those prehistoric women were doing.“By analyzing the bones of living people and comparing them to the ancient bones,we can start to explain the kinds of labor our ancestors were performing,” Macintosh said.What they found was that women's leg strength hasn't changed a great deal,but their arms used to be very powerful.Prehistoric women,the researchers found,had arm strength 11%—16% stronger than those of modern rowers,and 30% stronger than those of non-athletes.1.What does the study tell about prehistoric women?A.They were stronger than men.B.They had lighter bones than men.C.They did tough tasks as the men.D.They spent most time staying at home.2.What problem did previous studies on prehistoric bones have?A.They lacked enough comparison.B.They only studied men's bones.C.They focused little on bones.D.They ignored the lifestyles.3.What does the underl ined word “that” in Paragraph 3 refer to?A.Bones' structure.B.Bones' thickness.C.Bones' response to stress.D.Bones' stress from hard labor.4.What can we learn from the last paragraph?A.It's still hard to explain our ancestors' lifestyle.B.Prehistoric women went through much suffering.C.Women's arms have become much stronger over time.D.Prehistoric women are stronger than contemporary females.[解题导语]本文是一篇说明文,研究表明:7 000年前女性的臂力比现在专业运动员的都要强。

课时作业(十七)Ⅰ.阅读理解A[2019·北京海淀区期末] As the world's population grows,farmers will need to produce more and more food.And large farms are increasingly using precision farming to increase yields(产量),reduce waste,and reduce the economic and security risks that inevitably accompany agricultural uncertainty.Traditional farming relies on managing entire fields—making decisions related to planting,harvesting,irrigating,and applying pesticides and fertilizer(农药和化肥)—based on regional conditions and historical data.Precision farming,by contrast,combines sensors,robots,GPS,mapping tools and data-analytics software to customize the care that plants receive without increasing labor.Robot-mounted sensors and camera-equipped drones(无人机) wirelessly send images and data on individual plants to a computer,which looks for signs of health and stress.Farmers receive the feedback in real time and then deliver water,pesticides or fertilizer in adjusted doses(剂量) to only the areas that need it.The technology can also help farmers decide when to plant and harvest crops.As a result,precision farming can improve time management,reduce water and chemical use,and produce healthier crops and higher yields—all of which benefit farmers' bottom lines and conserve resources while reducing chemical runoff.Many small businesses are developing new software,sensors,and other tools for precision farming,as are large companies such as Monsanto,John Deere,Bayer,Dow and DuPont.The U.S. Department of Agriculture,NASA and the National Oceanic and Atmospheric Administration all support precision farming,and many colleges now offer course work on the topic.In a related development,seed producers are applying technology to improve plant characteristics.By following individual plants over time and analyzing which ones flourish in different conditions,companies can relate the plants' response to their environments with their genomics(基因组学).That information,in turn,allows thecompanies to produce seed varieties that will grow well in specific soil and weather conditions.This advanced technology may also help to improve crop nutrition.Farmers do not universally welcome precision agriculture for various reasons,such as high equipment costs and lack of access to the Internet.The technology may bring great challenges to experienced farmers who are not good at computers.And large systems will also be beyond the reach of many small farming operations in developing nations.But less expensive,simpler systems could potentially be applied.For others,though,cost saving in the long run may reduce the financial concerns.And however reticent some farmers may be to adopt new technology,the next generation of farmers are likely to warm to the approach.1.Why does precision farming differ from traditional farming?A.It provides real time information about target crops.B.It relies on regional conditions and historical data.C.It offers plenty of water,pesticides and fertilizer.D.It guarantees high yields with more labor.2.What can we learn about precision farming?A.The government holds a cautious attitude.B.It draws positive responses from businesses.C.Seed producers have already made huge profits.D.Large systems will soon be built in developing nations.3.What does the underlined word“reticent” in the last paragraph probably mean?A.Disappointed. B.Confused.C.Shocked. D.Unwilling.4.What is the best title for the passage?A.Precision Farming Increases Crop YieldsB.More Challenges Faced by Modern FarmersC.Development of Farming Systems in the U.S.D.Traditional Farming Is Gradually Disappearing[解题导语]精细农业通过各种先进的技术手段让耕种者实时得到信息,减少浪费,提高产量,但是先进的未必是可接受的,大的农业公司愿意采用新技术来耕种,但农民们却未必愿意。

课时作业(九)Ⅰ.阅读理解[2019·山东菏泽一模] It's easy to think that the globe's vast oceans would be effective barriers to the movement of land animals.An elephant can't swim across the Pacific,after all.But it turns out that plenty of plants and animals have unintentionally floated across oceans from one continent to another.Now comes evidence that tiny trapdoor spiders(活板门蛛) made such a journey millions of years ago.Moggridgea rainbowi spiders can be found on Kangaroo Island,which sits off the south coast of Australia.“These spiders build a silk-lined burrow(洞穴) in the ground,”noted Sophie Harrison,a biologist in Australia.The burrow and the trapdoor provide these spiders with shelter and protection.They also offer them an out-of-sight spot from which they can wait for approaching prey(猎物) .There is evidence,though,that the ancestors of them might have traveled millions of meters to get to Australia from Africa.That isn't as unlikely as it might at first seem.Australia used to be connected to other continents,long ago,as part of a supercontinent called Gondwana.And humans have been known to transport species(物种) all over the planet.But there's a third option.The spiders might have rafted(乘筏) long distances across the sea.To figure out which story was most likely true,Harrison and her colleagues looked at the spider's genes.They looked at the genes in seven Moggridgea rainbowi spiders from Kangaroo Island,and five species of Moggridgea rainbowi spiders from South Africa.The Australian and African spiders split off from a common ancestor some 2 million to 16 million years ago,the genes showed.If a large swatch(块) of land washes into the sea,filled with arachnids(蛛形纲动物),the spiders may be able to hide themselves throughout the journey.Plus,they can “hold their breath” and survive on stored oxygen during periods of temporary flooding,the researchers note.1.What is the common belief about land animals according to the text?A.They are sensitive to natural disasters.B.They are unlikely to move across oceans.C.They can't make a long ocean voyage.D.They float across oceans accidentally.2.What does the underlined word “them” in Paragraph 3 refer to?A.The biologists. B.The Australians.C.The spiders. D.The prey.3.How did the researchers conclude Australian and African spiders are from a common ancestor?A.By comparing their genes.B.By observing their living habits.C.By making changes to their genes.D.By studying their physical characteristics.4.What could be the best title for the text?A.These Spiders Traveled Globally to Hide ThemselvesB.These Spiders Became More Adaptive When TravelingC.These Spiders Crossed an Ocean to Australia forSurvivalD.These Spiders Crossed an Ocean to Become AustralianSpiders[解题导语]本文是一篇说明文。
