B．Touched.C．Happy. D．Puzzled.3．What does Jonathan Williams think of his study in movie theaters?A．Creative. B．Unsuccessful.C．Systematic. D．Meaningful.4．What is the best title for the passage?A．Watching Movies Is Good for Our EmotionsB．The Useful Role of Chemical Signals in the AirC．Our Breaths Show Our Emotions at the MoviesD．Reasons for Levels of Carbon Dioxide in TheatersBScientists have known for decades that having measles(麻疹) suppresses kids’ immune systems for several weeks or months，leaving them illequipped to fight off pneumonia，bronchitis and other infections.Now a team of researchers has suggested that the measles virus may also leave a longerlasting sort of “immuneamnesia(免疫缺失)” that makes it harder for peopleto stave_off other illnesses for two years or more.“That reemphasizes the importance of vaccination(疫苗)，” said biologist Michael Mina，lead author of a paper that was published in the journal Science.“There may be a longlasting impact that you can’t undo if your child gets measles，” he said.“I hope this study can impress upon people the danger measles poses.”The researchers used what Mina called “an unconventional approach” to search for the longlasting immune system effects.Previous work in monkeys suggested that monkeys with the disease lost white blood cells their bodies had trained to fight off other illnesses，leaving them more likely to be infected.To test if a similar thing may occur in humans，the group mined historical data to find out the relationship between measles incidence(发病率) and deaths from other infectious diseases.They turned to data from England and Wales—developed nations where disease levels are generally low，allowing a lessconfused view of measles’ effects.Studying measles incidence and deaths from infectious disease both before and after the introduction of the measles vaccine in the UK in the 1960s，Mina and the team saw a sort of shadow effect，where deaths from a variety of nonmeasles infectious diseases closely tracked measles incidence.The more measles in a population，the more deaths from other illnesses in the 28month period that followed.“Really it didn’t matter what age group，what decade or what country，” said Mina.“They all showed consistent results...what we’re suggesting happens over the long term is that your immune system works fine，but it has forgotten what it previously learned.”Some researchers who were not involved in the work questioned whether the reductions in deaths as measles cases declined may have had more to do with improving nutrition and smaller family size than with prolonged immune suppression.Others thought the paper’s opinion of yearslong suppression was seemingly reasonable but said they could not comment on the mathematical models the group used.To know for certain what was behind the effect the group saw，Mina agreed，scientists would need to look at immune cells and observe their behavior.He said he would like to push the work in a more traditional direction：back into the laboratory.5．Why did Mina call their research method “an unconventional approach”？A．Their research was based on the historical data.B．Their research compared monkeys with humans.C．They only paid attention to developed nations.D．They discovered a sort of shadow effect.6．According to Mina，what is the significance of their research?A．They warned people that measles can result in other infectious diseases.B．They carried out the research on measles in an unconventional approach.C．They showed how dangerous measles is and the importance of vaccination.D．They found out the disease levels are generally low in developed nations.7．The underlined phrase “stave off” in Paragraph 2 is close st in meaning to “________”．A．keep away B．survive fromC．search for D．turn down8．Which of the following may be the best title of the passage?A．Measles Has Been the Origin of Other Diseases and DeathsB．New Research Conducted into Measles Has Been Widely QuestionedC．Study Points to Yearslong Immune System Misfortunes from MeaslesD．Damage Caused by Measles to the Immune System Could Last Several Weeks Ⅱ.佳作背诵(科普知识与现代技术)你的美国笔友Tom来信和你讨论个人信息保护问题，让你就如何保护个人信息给他一些建议。

科普知识类(2013·福建卷·B)Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can’t wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.“I’d use it if I were hanging out with friends at 3 a.m. and going to the bar and wanted to see what was open,”said Walter Choo, 40, of Fort Greene.The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented(增强的)reality, a technology already available on smartphones and tablets(平板电脑)that overlays information onto the screen about one’s surroundings. So, for example, if you were walking down a street, indicators would pop up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.“As far as a mainstream consumer product, this just isn’t something anybody needs,”said Sam Biddle, who writes for . “We’re acc ustomed to having one thing in our pocket to do all these things,”he added,“and the average consumer isn’t gonna be able to afford another device(装置)that’s hundreds and hundreds of dollars.”9to5Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones.“It’s just like smartphones 10 years ago,”Weintraub said.“A few people started getting emails on their phones,and people thought that was crazy.Same kind of thing.We see people bending their heads to look at their smartphones,and it’s unnatural,”he said.“There’s gonna be improvements to that,and this a step there.”【文章大意】作者介绍了一种迷你手机型的眼镜的用途,以及不同的人对它的不同看法。

LampbrellaYou can’t always predict a heavy rain or remember your umbrella. ①But designer Mikhail Belvacv doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created lampbrella, a lamp post with its own rain sensing umbrella.The designer says he ②come up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street ad saw the street lamps ③lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy built into a street lamp.” he said.The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella ④on demand. Sensors then ensure that the umbrella offers p edestrians shelter whenever it starts raining.⑤In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used the canopy is closed.According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on my street where a lot of people walk but there are no canopies to provide shelter.灯柱伞你不会每次都预测到大雨到来或者记得带上雨伞。

B． Tammie Schrader.C． Justin Holladay. D． Zoran Popovic.3． What helped promote computer games in schools according to the text?a． The affordability of computers.b． The preferences of young teachers.c． The advertisements of commercial companies.d． Parents ’ support.e． Better games.A． a， b，e B ． a，b， cC． a， c，d D ． b，d， e4． The underlined phrase “fell flat” in Paragraph 3 probably means “ ________”．A． made no profitB． deserved attentionC． turned out successfulD． failed to get ideal effect5． What does Holladay think of using computer games in class?A． It is not as helpful as people thought it would be.B． It allows students to learn in a fun and helpful way.C． It sounds good but it was inconvenient to get feedback.D． It reduces the interaction between teachers and students.B(2016 ·浙江 )A scientist working at her lab bench and a six-month-old baby playing with his food might seem to have little in common.After all， the scientist is engaged in serious research to uncover the very nature of the physical world， and the babyis ， well， just playing...right？ Perhaps ， but some developmental psychologists(心理学家 )have argued that this“ play ” is more like a scientific investigation than one might think.Take a closer look at the baby playing at the table.Each time the bowl of rice is pushed over the table edge，it falls to the ground — and，in the process ，it brings out important evidence about how physical objects interact( 互相作用 ) ：bowls of rice do not float in mid-ai r ，but require support to remain stable.It is likely thatbabies are not born knowing the basic fact of the universe ； nor are they ever clearly taught it.Instead， babies may form an understanding of object support throughrepeated experiments and then build on this knowledge to learn even more about how objects interact.Though their ranges and tools differ，the baby’ s investigation and the scientist’ s experiment appear to share the same aim(to learn about thenatural world)， overall approach (gathering direct evidence from the world)，and logic (are my observations what I expected？ ) ．Some psychologists suggest that young children learn about more than just the physical world in this way— that they investigate human psychology and the rulesof language using similar means.For example， it may only be through repeated experiments ，evidence gathering，and finally overturning a theory，that a baby will come to accept the idea that other people can have different views and desires from what he or she has， for example， unlike the child， Mommy actually doesn’ t like Dove chocolate.Viewing childhood development as a scientific investigation throws light onhow children learn， but it also offers an inspiring look at science and scientists.Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort—the desire to explore，explain， and understand our world —is simply something that comes from our babyhood.Perhaps evolution(进化 )provided human babies with curiosity and a natural drive to explain their worlds ，and adult scientists simply make use of thesame drive that served them as children.The same cognitive( 认知的 ) systems that make young children feel good about figuring something out may have been adoptedby adult scientists.As some psychologists put it，“ It is not that children arelittle scientists but that scientists are big children.”6． According to some developmental psychologists， ________.A． a baby’ s play is nothing more than a gameB． scientific research into babies’ games is possibleC． the nature of babies’ play has been thoroughly investigatedD． a baby ’ s play is somehow similar to a scientist’ s experiment7． We learn from Paragraph 2 that ________.A． scientists and babies seem to observe the world differentlyB． scientists and babies often interact with each otherC． babies are born with the knowledge of object supportD． babies seem to collect evidence just as scientists do8． Children may learn the rules of language by ________.A． exploring the physical worldB． investigating human psychologyC． repeating their own experimentsD． observing their parents’ behaviors9． What is the main idea of the last paragraph?A． The world may be more clearly explained through children’ s play.B． Studying babies’ play may lead to a better understanding of science.C． Children may have greater ability to figure out things than scientists.D． One’ s drive for scientific research may become stronger as he grows.10．What is the author ’ s tone when he discusses the connection between scientists ’research and babies’ play?A ． Convincing.

2019届高考英语阅读理解精选细做：科技类
科技类1、 A buld-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunat ely, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5' 5' sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.The solar still works by creating a greenhouse under the plastic. Ground water evaporates(蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.1.What do we know about the solar still equipment from the first paragraph?A.It's delicate.B.It's expensive.C.It's complex.D.It's portable.2.What does the underlined phrase “the water catcher” in paragraph 2 refer to?A.The tube.B.The still.C.The hole.D.The cup.3.What’s the last step of constructing a working solar still?A.Dig a hole of a certain size.B.Put the cup in place.C.Weight the sheet's center down.D.Cover the hole with the plastic sheet.4.When a solar still works, drops of water come into the cup form .A.the plastic tubeB.outside the holeC.the open airD.beneath the sheet2、After ye ars of research and testing, the hybrid car was developed and put on the market. It’ s an interesting and exciting new improvement in today’ s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car’ s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that’s not how it works. The 144volt battery pack is actually recharged through the energy that i s produced when the car’s brakes are used. This is referred to as “regenerative braking”, because it generates electricity.Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.Have you ever ridden in a car with someone who ran out of gas? That probabl y wouldn’t happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OFGAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.1.Which of the following is true according to the passage?A.The hybrid car will be put on the market.B.Hybrid cars run faster than regular cars.C.When the hybrid car stops at a traffic light, the driver will get a warning.D.The burning of fossil fuels is one of the largest sources of air pollution.2.According to the passage, the word “hybrid” refers to ________.ording to the passage, the word "hybrid" refers to ________.A. a high-tech discoveryB.energy savingC.a new inventionD.a combination of two things3.“Regenerative breaking” is an important process of the hybrid car because ________.A.it allows the car to come to a quick stopB.it gives the driver a smoother rideC.it produces energy to charge the batteryD.it can control the speed of the car4.Which of the following is right about the EPA?A.They designed hybrid cars.B.They outlawed (宣布……为不合法) the burning of fossil fuels.C.They set important guidelines that help control pollution.D.Their main purpose is to protect endangered plants and animals.5.Which of the following is the reason for developing hybrid cars?A.They use less gas than regular cars.B.They' re safer to drive than most cars.C.They're more modern than other cars.D.They cost less than regular cars.3、Getting stitched(缝合)up by Dr.Robot may one day be reality.Scientists have created a robotic system which did just that in living animals without a real doctor pulling,the strings.Much like engineers are designing self-driving cars,the medical research is part of a move towardautonomous surgical robots,removing the surgeon’s hands from certain tasks that a machine might perform all by itself.Doctors wouldn’t leave the bedside they’re supposed to watch,plus they’d handle the rest of the surgery. In small tests using pigs,the robotic arm performed at least as well,and in some cases a bit better,as some competing surgeons in stitching together intestinal(肠的)tissue.“The purpose wasn’t to replace surgeons,”said Dr.Kim who led the project.“If you hav e all intelligent tool that works with a surgeon,can it improve the outcome? That’s what we have done.”If you’ve heard about machines like the popular Da Vinci system,you might think robots already are operating.Not really.Today many hospitals offer,robot-assisted surgery where surgeons use the machinery as tools that they control by hand,typically,to operate through tiny openings in the body.But robot-assisted surgery has been controversial,as some studies have shown it can bring higher costs without better outcomes.Kim’s team at Children’s Sheikh Zayed Institute invented the new STAR system—it stands for Smart Tissue Autonomous Robot—works sort of like a programmable sewing machine.They added sensors to help guide each stitch and tell how tightly to pull.But the approach wasn’t perfect.In the living animals,the robot took much longer and made a few stitching mistakes while the surgeon sewing by hand made none.Kim said the robot can be sped up.Fie hopes to begin human studies in two or three years.1.What’s the best title for the text?A.A new robotic systemB.A new-style way of stitchingC.The newly-designed driverless vehiclesD.Robot surgeons one step closer to reality2.What will surgeons do when Dr.Robot is used in surgery?A.They can help pull the strings.B.They rest at the bedside.C.They join in when necessary.D.They perform other surgery.3.Some people are against using robots in surgery probably because_________.A.they can be out of controlB.they will take shorter timeC.they may be expensive to useD.they are likely to cause great pain4.What can we infer from the text?A.Dr.Robot can take the place of surgeons.B.Dr.Robot will be developed at a fast pace.C.Dr.Robot has been tested with human trials.D.Dr.Robot can free doctors’hands i n the operation.4、 A hybrid electric vehicle (混合动力车) or HEV is a vehicle driven by the combination of petrol engine and electric motor. Terrence has been driving a HEV for five years. He really doesn’t understand why more people aren’t accepting them. “I probably spend about $ 7 a day on petrol,” the taxi driver told news. com. au. In his previous conventional vehicle Terrence said he was spending up to $ 30 a day on petrol, meaning he saves almost $ 6000 every year.The Toyota spokesman said this was quite a high saving and official tests estimate (估计) an average driver would only save about 33 percent off their current bill. This means a driver paying $ 30 a day on petrol would see their bill drop to about $ 20 using the hybrid. “A taxi driver that drives in built-up areas and spends little time on highways will notice a higher fuel saving,” he said. “Low speeds allow the electric motors to be used more and the petrol engine used less.”While some people are skeptical about how reliable hybrids are, Terrence said he had never run out of power. His Camry cost about $ 34,000 and so after five years, it’s nearly paid for itself. “For cab drivers, it’s a real advantage because of the cost-effectiveness,” he said.Terrence has no complaints about the car. “I l ove it, the calm and quietness of it, the simplicity of it—you just jump in and go. The maintenance(保养)is really low. But the only difficulty is finding someone to service the car as there are not many experienced mechanics(机修工).”Terrence said it’s “extraordinary” that more drivers aren’t buying more hybrid electric vehicles and that governments are not encouraging this more. “I think people have a view that you have to plug it in, which is not true. A lack of information about the cars may be stopping people from taking the plunge. It’s not promoted at all for the public to understand—it’s simplifying the actual owning of a car—you don’t have to do so many things to own it and run it, it’s just so much simpler. Why wouldn’t the government promote such a thing?”1.How much does an average driver save each day by driving a hybrid, according to the Toyota spokesman?A.$30B.$20C.$10D.$72.Terrence’s problem with his HEV at the moment is about the ________.A.speedB.powerC.priceD.service3.When saying “extraordinary”, Terrence thinks it is ________.A.understandableB.wonderfulC.doubtfulD.unbelievable4. What does Terrence think prevent the popularity of hybrid cars?A.The difficulty in servicing the car.B.The restriction of the government.C.The lack of information about HEV.D.The inconvenience with charging the car.5、Humans have been keeping animals as pets for tens of thousands of years, but Dr. Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.“Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don’t have to feed it, you don’t have to walk it, it won’t make a mess in your house, and you can go on a holidaywithout feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.It’s not clear whether robot pets can replace real ones. But studies do suggest that we can bond(紧密联系)with these smart machines. People give their cars names and kids give their toy animals life stories. It’s the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn’t need food, water or exercises, perhaps it will change how humans care about other living beings.” He said.So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets ne edn’t have a heartbeat might not be a far-fetched dream.1.What does the underlined part “sit well with” in Paragraph 3 most probably mean?A.Be refused by.B.Be beneficial to.C.Receive support from.D.Make a difference to.2.Who is fond of keeping robot pets?A.Those who are not fearful of real animals.B.Those who grew up with living beings.C.Those who will develop strong bond with their machines.D.Those who are often exposed to smart technology.3.What may be the best title for the text?A.Robot pets are comingB.The popularity of robot petsC.Living pets are dying outD.The advantages of robot toys6、Modern day robots may not be as entertaining as R2D2 or the robot from Lost in Space, but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.Robots make great explorers on planets, moons, and other landing areas. Aside from the earth, just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be complications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, and finding water are all performed much quicker and accurately by robots.The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never c omplain, they don’t require food or water, and they never need a bathroom break.Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars’ history.1.Which of the following would be the best title for the passage?A.The Development of RobotsB.The Discovery of Space ExplorationC.No Robots, No Space ExplorationD.Robots Are Used in Space Exploration2.According to the passage, which of the following is NOT true?A.The use of robots in space exploration costs more than the use of humans.B.It is dangerous for humans to explore other surfaces in the solar system except the earth.C.Both Spirit and Opportunity have found the evidence of water on Mars.D.Many different types of robots have explored the space successfully.3.The underlined word “withstand” most probably means “______”A.remainB.bearC.defeatD.develop4.What is the writer's attitude in this passage?A.Negative(消极的)B.Critical(批判性的)C.Subjective(主观的)D.Objective(客观的)7、US private rocket company SpaceX has announced that two private citizens have paid to be sent around the Moon. The mission (任务) is planned for late 2018. SpaceX CEO Elon Musk said, "This presents an opportunity for humans to return to deep space for the first time in 45 years."The two unnamed people will fly aboard a spaceship which is set for its first unmanned test flight later this year. The co-operation of America's NASA space agency had made the plan possible. Mr. Musk said, "The two passengers will travel faster and further into the solar system than any before them." Like the Apollo astronauts before them, these individuals will travel into space carrying the hopes and dreams of all humankind, driven by the universal human spirit of exploration."We expect to conduct health and fitness tests, as well as begin initial training later this year. The first mission would be unmanned, and the next one―with crew―was expec ted in the second quarter of 2018," the rich businessman and inventor said, "The first passengers are entering this with their eyes open, knowing that there is some risk here. They're certainly not childish, and we'll do everything we can to reduce that risk, but it's not zero."The space tourists would make a circle around the Moon, scanning the lunar surface and then going well beyond. However, the mission will not involve a lunar landing. "If NASA decided totake part in a lunar fly-by mission, then the agency would have privilege," Mr. Musk said. The US has not sent astronauts to the Moon since the early 1970s.1.Which of the following statements is true according to the text?A.The two tourists can't afford to fly around the moon.B.Space travels are rooted in the spirit of human exploration.C.Initial training is expected to be conducted at the beginning of 2018.D.The two tourists are expected to fly at a slow speed.2.The agency has privilege because ______A.it needs co-operation with Mr. MuskB.it has previous technical skillsC.it will be able to remove all the risksD.it has to make money for research3.Where can you most probably read the text?A.In a textbook.B.In a science fiction.C.In a travel brochure.D.On a news website.4.What can be a suitable title for the text?A.The Coming Moon Trip of Two Private CitizensB.An Opportunity to Explore Space for the First TimeC.A Paid Trip Planned by SpaceX to 'Land on the MoonD.Two Unmanned Missions of Circling around the Moon8、 A 10-year-old boy rides his bicycle slowly to a busy crossing. In front of him, cars and SUVs speed by, without pausing. He waits for a gap in traffic. When he sees one, he pushes off, gaining speed. But by the time he's halfway across, a car is almost coming in front of him. He makes it to the other side—but just barely. This scene usually happens across the country, but in this case, it occurred in a completely safe environment.The bike is stationary. The street is actually a laboratory at the University of Iowa, surrounded by three huge screens. The ‘‘ cars ’’ are 3-D virtual images. And the entire process is observed byresearchers who are trying to understand the factors that put children at risk when crossing the street on a bike or on foot.Crossing the street is one of the first experiences in a child's life. The researchers in Iowa are looking to learn more about that decision-making process with the goals that include giving parents information that could help them when they’re discus sing safety with young children. The risks children face on the road are real: 531,340 children were injured in 2014 on a bicycle.Most of the data the team has collected focus on children crossing the street on bicycles. Researchers record when kids believe it's safe to cross the street, children in the 10-12-year-old group often are actually close to adults in terms of the gaps they think safe to cross. The problem is how well they are able to act on those judgements.“Their timing of movement is not as good as adults,” Plumert, one of the researchers said. "They delay when they start crossing. As a result,they actually have less time to spare before the next car comes."When adults anticipate(预见) a gap in traffic after an approaching car passes, they'll actually begin crossing while that car is still in front of them. Children wait until that first car hasgone by completely, giving them less time to cross before the next car nears.1.What does the first paragraph mainly tell us?A.An experiment being done on kids riding bikes.B.An accident which happened at a busy crossing.C.A scene which was filmed on a country road.D.A terrible case made up by a group of researchers.2.What does the underlined word "stationary" most probably mean?A.Moving slowly.B.Speeding up.C.Remaining still.D.Being in danger.3.What can we infer from the third paragraph?A.Riding a bicycle poses a risk to children.B.Crossing a street on foot is very safe to kids.C.Parents know little about safety on the road.D.Drivers often fail to spot the cycling children.4.What is the result of the experiments?A.Children’s judgement on distance is usually not correct.B.Children usually cross while the car is still in front of them.C.Children can’t wait for the approaching cars to pass by.D.Children have less time to cross by waiting for the cars to go by completely.答案以及解析1答案及解析：答案：1.D; 2.B; 3.C; 4.D解析：1.推理判断题。

2019年中考英语专项练习—阅读理解之科普知识与现代科技含答案第一节阅读理解。
根据短文内容，从每题所给的A、B、C、D四个选项中选出最佳答案。
AArtificial intelligence(AI，人工智能)can help us make phone calls. It can guide us to where we want to go. It can play games. And now，AI can do even more things.Researchers from Microsoft have created the first machine translation system that can translate news articles from Chinese to English.The researchers tested the system by asking it to translate hundreds of sentences taken from news stories. Then，language experts compared the results to the translation that were done by humans. The experts said that the system's translations were as good as the human translations.Experts used several methods to improve the system's translation abilities. “Much of our research is really learned from how we humans do things，” lead researcher Liu Tieyan said.One method is called dual learning(对偶学习). In this method，the system translates every sentence from Chinese to English，as well as translates the sentences back from English into Chinese. This way，the system can improve itself and learn from its own mistakes. This is similar to what humans do to make sure their translations are exact.Another method makes use of deliberation networks(推敲网络)．The researchers taught the system to repeat the process of translating the same sentence over and over. Gradually，the system can improve the quality of its translations. This is similar to how people correct their own writing by going through it again and again.( )1. Microsoft created a system that can ________.A. make phone callsB. give people directionsC. play games with peopleD. translate news articles( )2. What did the experts say about the system's translations?A. They were not exact.B. They were as good as human translations.C. They were better than human translations.D. It's hard to tell whether the translations were correct.( )3.

Kenneth's wearable sensors will keep old people at home.CTechnology is everywhere. We see it any place we go and， in fact， almost all of us carry some piece oftechnology with us every time we leave the house. What I always forget， though， is just how useful and powerful technology can be when we want to help othersThere is not a single room in my house that does not have some electronic devices（设备） lying around init. Whenever I am at home， I am almost always using at least one electronic device. If you walked into my living room on any given day， you would find that， first， I have the television on. At the same time， I usually have my laptop resting on my knee， or I will be using my mobile phone， Even when i＇m not at home I am always using my phone， and at work or in cafes， I sit down and connect to the local wireless network on myopic.I must say that I waste a lot of time on the computer and the time I spend on it could be much better spent if I were to take up a little online volunteeringThe technology we carry about everywhere can have a great power to do good for the world and to help others and recently I discovered just how much online volunteering there is to do in the world. From using your language skills to do translations， to developing and managing projects and helping with IT work， there is so much that so many people can do to help people in their own countries and across the world. The United Nations， in fact， has a huge page with ＂Volunteers Recruited＂ on its website.This work can support the poor and help charities who cannot pay for staff. Many organizations only require you to work an hour a week-some even less. And the support provided by online volunteers can really help make a difference to those in need.( )1. From Paragraph 2， we can know that the writerA. uses technology a lotB. works in a cafeC. is a computer engineerD. likes modern music( )2. The underlined word Recruited＂in Paragraph 4 means“”A. OrderedB. WantedC. VisitedD. Warned( )3. In the writers opinion， people should spend more time with technology.A. working on computer programsB. keeping the Internet safeC. inventing electronic productsD. helping people in need( )4. What can be the best title for the passage？A. Website DesignB. Internet OrganizationsC. Online VolunteeringD. Online TranslationDDo you find it difficult to put down your mobile phone?If yes，you're not alone. These days，many people are facing the stress in the use of mobile phones. They reach for their mobile phones when they wake up in the morning，and keep checking their social media apps to get the latest updates(更新)．A report from Google shows that 70 percent of people don't want to spend much time on their phones. This is why Google introduced an app called Dashboard for the new Android operating system(安卓操作系统). This new app includes functions(功能) that help users manage the time. For example，users can see how many times they've unlocked their phone，how many times they've checked their social media apps，and how much time they spend on each app every day.Once the users see this information，they'll be able to make some changes. With the App Timer(计时) function，users can set a time limit for how long they can use each app for every day. After they've hit the limit，they won't be able to use the app until the next day. And with another function，the app gets incoming calls silent when the user puts the phone face down.If people truly want to make full use of their free time instead of losing hours on their phones，these new functions are just one way of doing that.After all，who needs to use an app to stop you from using other apps? The easiest answer would be just to use your willpower.( )1. Where does the users' stress come from?A. Too many updates of the apps.B. Too many functions of the apps.C. Too much information they receive.D. Too much time they spend on the phone.( )2. Which of the followings is NOT included in Dashboard's functions?A. It stops the users from using their willpower.B. It checks how much time the users spend on apps.C. It lists how many times the users have unlocked the phone.D. It shows how many times the users have checked social media apps.( )3. What does the underlin ed word “limit” in Paragraph 4 mean?A. 目的B. 标准C. 许可D. 限制( )4. What does the writer think of Dashboard?A. Its design is perfect.B. It may be helpful to some people.C. It needs more functions.D. It has too many functions.EShyness can be an unhappy feeling. But the good news is, you're not alone. Scientists say that more than 40 percent of teenagers and adults consider themselves shy. Shyness is feeling a little nervous or as if you want to hide when you're around other people or in a new situation.___ Scientists say such things as genetics（遗传基因）， life experiences， and environment can influence whether a person is shy. For example, in some families, everybody seems to be shy.What happens if you are shy? Well, being shy may cause you to avoid or miss opportunities you would enjoy. How do people overcome (克服)shyness? This is what Gilbert tells us. "When I started off trying to get over being shy, I decided to do little steps at a time, including practicing smiling and saying hi to people. And it worked for me. “But shyness is not the kind of thing that most people can get over overnight. Overcoming shyness take time and needs practice.Here are some tips given by scientists.Think of what to talk about before you leave home. Prepare things to talk about before you're in a social situation. For example, if you know your classmates are interested in an upcoming event, learn about it so you can join in the conversations.Let people know you're shy. If you're shy, just show it. Instead of letting people guess, tell them the truth. Explain that you are shy and feel nervous but enjoy talking to people.Make things easy for the other person. Remember, you’re not the only shy person around. Do what you think might help others feel good-for example, say hello or smile.Pick one social skill to practice at a time. Start simply. For example, smile or be the first person to say hi. Choose skills you feel comfortable enough with to practice for a day, a week, a month, or even a year.( )1. Which of the following can be put in the blank in Paragraph2?A. What is shyness?B. What makes people shy?C. Can shyness be good for us?D. Can we overcome shyness?( )2. The example of Gilbert in Paragraph 4 is given to _____.A. show how people overcome shynessB. introduce a shy girl called GilbertC. tell the right time to practice smilingD. explain the steps of overcoming shyness( )3. What does the underlined word "overnight" in Paragraph 5 most probably mean?A. Correctly.B. Suddenly.C. Slowly.D. Finally.( )4. Which of the following is the right way to overcome shyness?A. Don’t let others know that you are shy.B. Wait for others to say hello to you first.C. Choose several skills to practice at a time.D. Get ready before you join in a social situation.FPossible EarthLike Planet Next DoorScientists say they discovered an earthlike planet outside our solar system(太阳系). It is a planet that could support life.This planet is just 4.2 light years away from us. It is so close that space scientists have considered it as a next door neighbor. They say it could be reached by an unmanned spaceship before the end of the century—in time for people alive today to see it.An international team of scientists found the planet moving around the star called “Proxima Centauri”. The result came out last month from the scientific magazine Nature.Scientists have long thought that a planet with water is important for life. And it has to be neither too hot nor too cold. The newlydiscovered planet is a little larger than earth. Scientists have named it Proxima B. It moves around its sun，Proximal Central once every 11 days.American scientists have been using instruments for years to look for earthlike planets. In 2013，scientists' best guess was that there are about one billion(1,000 million) “earths” in space.Alan Boss is the chairman of a group for outer space research. He said that Proxima B not only confirms(确认) the discovery of a planet，but also increases the number of other possible “earths” greatly.Boss said it is possible，even likely，that most stars have at least one earthlike planet，which he considers surprising.So from the early number of a billion，this new research suggests there may be as many possibleearthlike planets as there are stars in the Galaxy(银河系). That is，anywhere from 250 billion to 500 billion“earths”．This makes the possibility of living things increasingly likely. Boss said he believes human beings will be able to show that there is life in places besides earth in his lifetime. “I am 65，” he said，“ but I expect to still be alive when it happens.”( )1. When will it be possible for an unmanned spaceship to reach Proximal B?A. In about eighty years.B. In about 4.2 years.C. In about eleven day.D. In about one billion years.( )2. In the fourth paragraph，the writer thinks that ________ is necessary for life.A. waterB. lightC. airD. wind( )3. What does the underlined word “This” stand for in the last paragraph?A. Scientists have discovered an earthlike planet last month.B. There are far more earthlike planets than people thought.C. Proximal B is not far from earth and is just like our neighbor.D. The Galaxy will be the only place for living things to live in.( )4. What does Alan Boss mean by saying “but I expect to still be alive when it happens”？A. His health is in good state and he's sure he will live a long life.B. Science is developing much faster than ever in recent years.C. Scientists may soon find fact that there's life on other planets.D. America is far ahead of other countries in space research.GBeauty sleep is a real thing, researches have shown that people who have enough sleep look more attractive (有魅力的) to others.A few bad nights is enough to make a person look "especially" more ugly, their sleep experiments show.The researchers asked 25 university students to join in their sleep experiment. They were asked to get a good night's sleep for two nights.A week later, they were asked to sleep for only four hours every night for two nights in a row.The researchers took make-up free (素颜) photos of the volunteers after both the good and the bad sleep.Next, they asked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health, and sleepiness, as well as asking them: "How much would you like to make friends with this person in the picture?"The strangers were good at judging if the person they were looking at was tired, and, if they were sleepy, their attractiveness score was low.The strangers also said they wouldn't want to socialize with the tired students. The researchers say this is natural for people. An unhealthy-looking face makes people run away. In other words, people don't want to hang around with people who might be ill.Dr. Brewer, an expert at the University of Liverpool said "Judgement of attractiveness is often unconscious (无意识的), hut we all do it, and we are able to judge on even something small like whether someone looks tired or unhealthy. This study is a good reminder of how important sleep is to us." ( )1. When did the researchers take make-up free photos?A. After two nights good sleep.B. After two nights bad sleep.C. Before the experiment.D. After both two nights good sleep and two nights' had sleep.( )2. The researchers asked the strangers to do the following except _______.A. telling who looked healthierB. telling who didn't have many friendsC. telling who missed a lot of sleepD. telling who was attractive( )3. What kind of friends did the strangers like to make?A. The people who were tired.B. The people who were sleepy.C. The people who were unhealthy.D. The people who were attractive and energetic.( )4. What does the underlined word "socialize "mean in Chinese?A. 合伙B. 玩耍C. 交往D. 共事( )5. According to the passage, which of the following is the best title?A. Beauty sleep, More attractiveB. More sleep, More FriendsC. Less sleep, Fewer friendsD. No attractiveness, No friendsHImagine having a simple app(应用程序) that works like this: When you need help，just open the app，touch the “not OK” button and a text message will be sent to five preselected(预先选定的) people，along with a location(位置) to show where you are. The message reads，“Hey，I'm not OK. Please call me，text_me，or come to find me.”US teenagers Hannah Lucas,15，and her brother Charlie,13，have created an app called not OK. People just need to pay $1.99(12.5 yuan) each month to use it.Hannah was inspired(启发) to create the app during a dark time in her life last year. She suffered from a disease that caused her to pass out at school. Other kids sometimes bullied(欺凌) her about this. She felt sad and wanted to find an app that would allow her to get help when she wasn't feeling OK.She asked her brother Charlie，whose nickname is “Tech Support”，to find such an app. When they couldn't find one，they decided to create one themselves.They came up with some designs for the app first. Charile took a programming class last summer and built a website for the app. Hannah also shared her idea in her summer business class. Some app developers showed interest and decided to help her. At last，the app came out in the US and Canada on January 31.Hannah is happy that her app is helping others. “It makes everything I went through last year worth it，” she said.( )1．Who will know you're in trouble when you touch the “not OK” button?A. Five pres elected people.B. Five family members.C. Five app developers.D. Five close friends.( )2．What do the underlined words “text me” in Paragraph One probably mean?A. Send me a report.B.

The right order of the following statements about the invention of the app is________ .a. Hannah suffered from a disease last year.b. Charlie took a programming class last summer.c. The app came out in the US and Canada in January.d. Hannah and Charlie failed to find such a useful app.A. c，d，a，bB. c，d，b，aC. a，d，b，cD. a，d，c，b( )5. The best words to describe the app are________.A. simple and helpfulB. pleasant and dangerousC. expensive and creativeD. interesting and pres electedIIs there an important exam right around the comer? You might be starting to fear, thinking that there' s no way for you to get a good grade because of the little time left to study. This is something all students may worry about. But you should accept the fact that you have to take theexam no matter how much you want to avoid it.Thankfully, there are several ways to help you get at least a passing grade. You may have a try.

Influenced by the launch of the first manned mission to Mars next month，you will most likely get a gift card for a space trip.The interest in trips,100km above the surface of the Earth，has grown steadily since such a trip began. However，the market has grown much larger this year since the official announcement of the Mars mission. More lowcost space-lines have entered the market and you can now find flights for such a trip for as low as $3,495. It's very reasonable.Space tourism(旅游业；观光业)is one of the markets that have developed fast during the last decade，with the opening of the Star bright Hotel on the moon as well as the low orbital hotels that started accepting guests. However，accommodation in space is still expensive for the average household，so the suborbital(亚轨道的) flights with thirtyminute weightlessness during the threehour flight will for some time be the most popular trip.However，the space-lines might in the future face fierce competition between space elevators(太空升降舱)，like the one that is projected to start construction within two years. Once it is fully functional，it will start to ship cargo to space. But it will accept passengers as soon as possible to get back the large investment. Even if the elevator becomes successful，it will take several years before there are more elevators in the world to get in the competition for space traffic with the space-lines.Those who are looking for a little bit of adventure and have extra money to spend may want to considera suborbital flight in space. While a suborbital flight may not be the space mission that you have always dreamed of，it will give you the rare opportunity to see what our planet looks like in a highaltitude flight outside our atmosphere. So before you enjoy a trip by elevator to space，enjoy a suborbital flight first.( )1. From Paragraph 1，what will happen in January,2031?A. A gift card will be taken to Mars.B. Mars will be explored for the first time.C. Man will go to Mars for the first time.D. An affordable space trip will come true.( )2. The underlined “average” can most probably be replaced by “________” in this passage.A. commonB. highincomeC. lowcostD. lowincome( )3.

To start the construction of more space elevators.D. To get back the large investment.( )4. Which of the following is NOT TRUE according to the passage?A. Space tourism has developed fast during the last ten years.B. A suborbital fight may be the space mission that you have dreamed of.C. The suborbital flights will be the most popular trip for some time.D. Even though the elevator becomes successful，we still wait for a few years to see more elevators come out.( )5. We can know from the passage that________.A. the low orbital hotels have opened since a space trip beganB. within two years，space elevators will begin to ship cargo and people to spaceC. during the suborbital fights，you will experience 30 minutes weightlessnessD. if you want to meet your curiosity，you may try a suborbital fightKThere's much to see under the sea，but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out of to touch something and completely missing it.Objects under water will appear larger than they would on the surface，too. Be careful not to tell any stories about the big fish that got away. That fish might not be so big after all! It's just because sometimes things can seem to be as much as about 33 percent bigger in water!What's more，in deeper water，colors just don't seem as bright. In fact，it looks as if some colors are missing. Remember the color of an object results from the wavelengths(波长) of light that are reflected (反射) from its surface. And light is taken in as it moves down through the water.Swimmers wear wet suits to keep warm underwater. Let's take a bright red，yellow，and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths，the longest among these three colors，are missing. As you go down deeper，the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater，you will look terrible，like a ghost(鬼怪)! And you have to wait for your return to the surface to enjoy the bright colors again.( )1. You miss the object under water when you want to touch it because ________.A. your eyesight is quite poorB. you are not quick enoughC. it is not as close as it seemsD. it disappears very quickly( )2. The example of the wet suit is used to explain the change of ________ of an object underwater.A. the sizeB. the colorC. the positionD. the weight( )3. The underlined word “descend” probably means “________” in Chinese in this passage.A. 上升B. 酒污C. 屏息D. 下潜( )4. Which of the following is true?A. A fourmeterlong fish looks three meters long underwater.B. The wavelengths of red light are longer than those of blue light.C. Much water will be taken in by the swimmer deep in the wave.D. You will see a ghost if you go as deep as 6 to 9 meters into the sea.( )5. The best title of this passage is ________.A. The Standard of Color UnderwaterB. The Direction of Light UnderwaterC. The Brightness of Color UnderwaterD. The Behavior of Light UnderwaterLArtificial intelligence(人工智能)，or AI in short，is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.AI is rapidly catching up with the human ability to read faces. As a result，facial recognition(识别) is used a lot in the world. Chinese police use this technology to identify criminals(罪犯). Once they caught a criminal when he attended a concert. It also checks the ID of ridehailin g(网约车) drivers and lets people pay for things with a smile.AI is also used in selfdriving cars，which are believed to be the future of driving. Most drivers may wave or nod at passersby to let them cross the street，but selfdriving cars don't have this a bility. Carmakers are testing a light signal system to help them “speak” to humans. The system can show what。

Disneyland.What，he thought，if his Tshirt had a cooling system he could turn on，at the tap of a smart phone app，when he needed it.Luckily，Mr Liedert does have the means to make the dream reality，for he works at the VTT Technical Research Centre of Finland，as one of a team there studying the rapidly growing field of microfluidics(微流控技术)．Cooling vests already exist(used by racing drivers，motorcyclists and people who work in hot conditions)．But the tubes through which the cooling water is being pumped，and the vests’need to be connected to outside units that cool this water，make them huge and clumsy.Mr Liedert thought VTT’s microfluidics department could do things better.As its name suggests，microfluidics is the art of building devices that handle tiny amounts of liquid.Inkjetprinter cartridges(喷墨打印机墨盒) are a familiar example.Less familiar，but also important，are “labsonachi p”(芯片实验室)．These are tiny analytical devices that transport fluids such as blood through channels half a millimetre or less in diameter(直径)，in order to carry them into what holds analytical reagents(试剂)．Sensors，then detect the resulting reactions and provide an instant analysis of a sample(样本)．Designing labsonachip is the VTT microfluidics department’s day job.One of its chips，for example，can tell whether water is affected by the bacteria that cause Legionnaires’ disease.The department’s biggest contribution to the field，though，is to have developed a way of printing microfluidic channels onto large rolls of thin，flexibleplastic.It works by passing the plastic between two heated rollers，one of which contains raised outlines of the required channels.As the rollers squeeze the plastic they create a pattern of channels into one surface.A second plastic film is then melted over the top as a cover.This process might，thought Mr Liedert，be suitable for printing a microfluidic cloth that was thin enough and pleasant enough to wear as a cooling vest.The group’s first model showed that such a material could indeed be made and used to circulate cooled water.They are also looking at ways the water being circulated through the microchannels might be cooled.They have identified two.One u ses a small heatexchange r，the details of which they are keeping secret at this stage.The other employs evaporation(蒸发)．It thus works in the same way that heat from circulating blood is removed by the evaporation of sweat.Whichever cooling system is applied，the electronics needed to power and control it would be shrunk into a small package contained on the back of the vest.This could be operated by hand or，as Mr Liedert originally envisaged in his Californian queue，by a wireless link to a smart phone.Moreover，what can cool down can also，if run in an opposite way，warm up.In Finland，where winter temperatures fall as far as －50 ℃，that might be the technology’s killer app.21．Microfluidics has been used in ________.A．racing cars B．printing industryC．testing material D．clothing industry22．We can learn from the passage that ________.A．VTT is a company which mainly works on the research into microfluidics B．the new cooling vest of VTT will be smaller and work more effectively C．the technology of microfluidics may have a positive effect on medical science D．heatexchanger as well as the way of evaporation will be used to cool the wearer23．________plays the key role in making the new cooling vest.A．The special cloth B．The cooling systemC．The tiny liquid D．The wireless link24．The underlined word “envisaged” most likely means “________”．A．imagined B．discoveredC．viewed

A．She might think it was right to revenge any injustice in professional life. B．She might think the employer was wrong to fire her for personal problems. C．The company carelessly gave her enough time to do the erasing.D．The company always interfered with its employees’ personal life.5．What can we infer from the last paragraph?A．Minor employees are supposed to be responsible for economic criminals.B．Of all crimes，computer theft is “the tip of the iceberg”．C．Computer crimes are all poorly done.D．There are more computer crimes committed by computer masters.Ⅱ.阅读表达Are you on Facebook almost every hour of the day？Do you think about being on Facebook even when you are not？If so，you’re suffering from Facebook addiction.Just like any other type of addiction，it can be harmful to a person’s overall life.However，following the few tips can help yourself overcome it.Admit your addiction to Facebook.Admission is the first step with any addiction.If not，then you can’t be helped.Ask yourself these questions：Are you on Facebook at least every hour？Do you wake up in the middle of the night with the desire to check your Facebook page？Does Facebook interfere with your job performance，family life or daily routine？If you said “yes” to most of these questions，then you could be addicted to Facebook.List the consequences for using Facebook.Many p eople don’t realize what negative impact Facebook has on their lives until they make a list.Think about what Facebook addiction is doing to your job，family environment and your overall lifeand list them all，which helps bring about awareness on what it is really doing to their lives.________.Go under the help section on Facebook and email customer service letting them get your account cancelled.For some people this is enough to help them overcome their addiction，but some others may end up turning to some other social networking websites，say，MySpace.In that case，you need to cancel internet access together.Seek a professional therapist.Recovering from any addiction can be difficult.Find a therapist specializing in addiction，even better yet someone who is familiar with Facebook addiction.The therapist will help you understand where your Facebook addiction stems from and what you can further do to recover from it.Don’t allow your addiction to Facebook to continue taking over your life and take action today.6．How does the author introduce the topic of the passage？(no more than 5 words) ________________________________________________________________________7．List three aspects Facebook addiction will have a bad effect on.(no more than 8 words)(1)________________________________________________________________________(2)________________________________________________________________________(3)________________________________________________________________________ 8．Fill in the blank in Paragraph 4 with proper words.(no more than 6 words)________________________________________________________________________ 9．Why does the author suggest seeking a therapist？(no more than 12 words)________________________________________________________________________________________________________________________________________________ 10．What’s the main idea of the passage？(no more than 8 words)________________________________________________________________________Ⅲ.佳作背诵(科普知识与现代技术)(2016·天津河北区三模)现代人越来越离不开手机。

2019届高三英语一轮复习专题训练卷之阅读理解（全国通用）：科技类1 Modern day robots may not be as entertaining as R2D2 or the robot from Lost in Space, but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.Robots make great explorers on planets, moons, and other landing areas. Aside from the earth, just about every surface in the solar system ij unsafe for humans to explore. The air on most othei planets is insufficient forunsafe for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be complications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, to finding water are all performed much quicker and accurately by robots.The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough | food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never complain, they don’t require food or water, and they never need a bathroom break.Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars’ history.1.Which of the following would be the best title for the passage?A.The Development of RobotsB.The Discovery of Space ExplorationC.No Robots,No Space ExplorationD.Robots Are Used in Space Exploration2.According to the passage, which of the following is NOT true?A.The use of robots in space exploration costs more than the use of humans.B.It is dangerous for. humans to explore other surfaces in the solar system except the earth.C.Both Spirit and Opportunity have found the evidence of water on Mars.D.Many different types of robots have explored the space successfully.3.The underlined word “withstand” most probably means “______”A.remainB.bearC.defeatD.develop4.What is the writers attitude in this passage?A.Negative.B.Persuasive.C.Subjective.D.Objective.答案：1.D; 2.A; 3.B; 4.D解析：1.标题概括题。

高考英语作文复习：话题作文 科学技术讲义
高考英语作文复习---话题作文距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理，能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料，希望可以帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！养成良好的答题习惯，是决定高考英语成败的决定性因素之一。
做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。
总之，在最后的复习阶段，学生们不要加大练习量。
在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。
英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。
越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。

【作文书写总纲】高中作文虽大约在100-120词左右，但也需要在书写前安排好文章结构，理清书写思路后再下笔写作，才能保证逻辑清楚，承接自然，首尾呼应。
称为“五确定”，一般可以按照以下几步：1、确定文章体裁。
是书信，还是议论文、说明文等。
即使是书信，也需要按照不同的书信类别进行分析准备，例如是否要写自我介绍；是否需要寒暄；是否需要时间落款2、确定文章段落。
一般段落在3-5段比较合适，段落太多会有冗余繁杂之感。
但有些文章也可以两段，例如通知或者是演讲稿，也可以满足要求。
3、确当各段内容和段落之间的过渡。
第一段往往起到引出话题的作用，安排2-3句话较为合适；二段为主要内容，在分层和衔接上要求较高，文章的主要句子主要在这里体现；三段一般为呼应和总结，安排2-3句话，这样的结构较为紧密完整，主次分明，逻辑清楚。

Williams started out measuring the air in a soccer stadium.He wanted to see if the fans’exhaled(呼出的) breaths might affect levels of greenhouse gases in the air.Carbon dioxide, which people breathe out，is one example.And he found the answer was no at least on a small scale.But he noticed levels of carbon dioxide shifted wildly whenever the crowd cheered.That got him wondering：Could the gases people exhale be influencedby emotions? So Williams went to the movies.He and his coworkers measured air samples collected over six weeks in two movie theaters.Overall,9,500 moviegoers watched 16 films includinga mix of comedy，romance，action and horror films.Then they looked for hundreds of chemicals in the air that showed up as people were watching particular movie scenes.theedgeonScenes that had people laughing or___seatswere especially_their_ofunique，the researchers reported.During screenings of TheHungerGames：CatchingFire，levels of carbon dioxide and isoprene(异戊二烯) were the highest at two terrifying moments.Because isoprene was involved in muscle movement，the researchers thought tense movie moments likely led to its highest level.Williams and his colleagues thought an increase in the amount of carbon dioxide was due to the viewers’ increased pulse andbreathing rates. Scientists need more data to make stronger links between human emotions and what’sin their breath.But Williams can see possible practical panies，for instance, could quickly measure the air during tests to see how people feel about new products. 1．What did Jonathan Williams find in the study conducted in a soccer stadium?A．Emotions affected the gases people breathe out.B．Human cheers changed levels of carbon dioxide.C．Human breaths affected levels of greenhouse gases.D．The exhaled chemicals were linked to what were eaten. 2．What does the underlined part “on the edge of their seats” in Para.5 mean?A．Nervous. B．Touched.C．Happy. D．Puzzled.3．What does Jonathan Williams think of his study in movie theaters?A．Creative. B．Unsuccessful.C．Systematic. D．Meaningful.4．What is the best title for the passage?A．Watching Movies Is Good for Our EmotionsB．The Useful Role of Chemical Signals in the AirC．Our Breaths Show Our Emotions at the MoviesD．Reasons for Levels of Carbon Dioxide in TheatersBScientists have known for decades that having measles(麻疹) suppresses kids’immune systems for several weeks or months，leaving them illequipped to fight off pneumoni a，bronchitis and other infections. Now a team of researchers has suggested that the measles virus may also leave alongerlasting sort of“immuneamnesia(免疫缺失)” that makes it harder for peoplestaveto_offother illnesses for two years or more.“That reemphasizes the importance of vaccination(疫苗)，”said biologist Michael Mina，lead author of a paper that was published in the journal Science.“There may be a longlasting impact that you ca n’t undo if your child gets measles，” he said.“I hope this study can impress upon people the danger measlesposes.”The researchers used what Mina called “an unconventional approach”to search forthe longlasting immune system effects.Previous work in monkeys suggested that monkeys with the disease lost white blood cells their bodies had trained to fight off otherillnesses，leaving them more likely to be infected. To test if a similar thing may occur in humans，the group mined historical datato find out the relationship between measles incidence(发病率) and deaths from otherinfectious diseases. They turned to data from England and Wales—developed nations where disease levelsare generally low，allowing a lessconfused view of measle s’effects.Studying measles incidence and deaths from infectious disease both before and after the introduction of the measles vaccine in the UK in the 1960s，Mina and the team saw a sort of shadow effect，where deaths from a variety of nonmeasles infectious diseases closely tracked measles incidence.The more measles in a population，the more deaths from other illnessesin the 28month period that followed.“Really it didn’t matter what age group，what decade or what country，” said Mina.“They all showed consistent results...what we’re suggesting happens over the long term is that your immune system works fine，but it has forgotten what it previouslylearned.”Some researchers who were not involved in the work questioned whether the reductionsin deaths as measles cases declined may have had more to do with improving nutrition and smaller family size than with prolonged immune suppression. Others thought the paper’s opinion of yearslong suppression was seemingly reasonable but said they could not comment on the mathematical models the group used. To know for certain what was behind the effect the group saw，Mina agreed，scientists would need to look at immune cells and observe their behavior.He said he would like to push the work in a more traditional direction：back into the laboratory.5．Why did Mina call their research method “an unconventional approach”？A．Their research was based on the historical data.B．Their research compared monkeys with humans.C．They only paid attention to developed nations.D．They discovered a sort of shadow effect.6．According to Mina，what is the significance of their research?A．They warned people that measles can result in other infectious diseases.B．They carried out the research on measles in an unconventional approach.C．They showed how dangerous measles is and the importance of vaccination.D．They found out the disease levels are generally low in developed nations. 7．The underlined phrase “stave off” in Paragraph 2 is closest in meaning to“________”．A．keep away B．survive fromC．search for D．turn down8．Which of the following may be the best title of the passage?A．Measles Has Been the Origin of Other Diseases and Deaths B．New Research Conducted into Measles Has Been Widely Questioned C．Study Points to Yearslong Immune System Misfortunes from Measles D．Damage Caused by Measles to the Immune System Could Last Several WeeksⅡ.佳作背诵(科普知识与现代技术)你的美国笔友Tom来信和你讨论个人信息保护问题，让你就如何保护个人信息给他一些建议。
