专题16 科普类说明文2019高考题D【2019·全国I】We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.32. What does the author think of new devices?A. They are environment-friendly.B. They are no better than the old.C. They cost more to use at home.D. They go out of style quickly.33. Why did Babbitt's team conduct the research?A. To reduce the cost of minerals.B. To test the life cycle of a product.C. To update consumers on new technology.D. To find out electricity consumption of the devices.34. Which of the following uses the least energy?A. The box-set TV.B. The tablet.C. The LCD TV.D. The desktop computer.35. What does the text suggest people do about old electronic devices?A. Stop using them.B. Take them apart.C. Upgrade them.D. Recycle them.【答案】32. A 33. D 34. B 35. A【解析】本文是一篇科普说明文。

I thought only I had that problem.哈我认为只有我有这个顾虑Luckily enough, if we want to use one of these things for stellar travel,幸运的是如果我们想用其中一个彗星进行星际旅行we have quite a few to choose from!我们的选择有很多！According to NASA,根据美国航天局there are around 3,600 comets that we currently know of.我们目前已知的彗星约有3600颗Beyond that, it’s believed that there are billions of other comets out there此外据说在遥远的柯伊伯带还有数十亿颗彗星orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud. 甚至是更远的奥尔特云围绕着太阳运行的What makes comets great for getting around in space彗星能够穿梭星际is that they can go SUPER fast.是因为其速度极快Yeah, this baby can fly!是的这小东西会飞！How fast they’re travelling depends on a bunch of different factors,它们的速度取决于多种不同因素but they can travel anywhere from a few thousand kilometers per hour,但在一定条件下它们的速度可以从时速几千公里to over 160,000 kilometers per hour under certain conditions.达到每小时超16万公里在任何地方飞行In fact, in 2016, scientists at NASA recorded2016年美国航天局的科学家们记录了a comet traveling at nearly 600 kilometers per second as it dove toward the Sun.一颗秒速六百公里驶向太阳的彗星That’s over 2 /million/ kilometers per hour!那超过了两百万公里每小时！To put that in perspective,就此展望if we could travel at 2 million kilometers per hour,如果我们能以每小时两百万公里的速度飞行then wecould get to Mars from Earth in around 28 hours,我们可以在一天多的时间里just little more than a single day,约28小时就可以完成火星之旅assuming the two planets were close together in their orbits. 假设轨道上有两颗行星距离很近Lining up the planets is the least of our worries though.我们可以在可控范围内排列行星While comets can go super fast,彗星的速度超快getting to them would be a big problem.登上彗星仍会是一大问题That’s because, not even considering how hard it would be to actually commandeer one,因为我们甚至没有考虑控制一个彗星有多难comets just don’t typically get that close to Earth.彗星一般离地球很远Hale-Bopp, a comet that made the news about two decades ago, 大概二十年前新闻上报道了海尔-波普彗星came closer to Earth than most comets do,它比大多彗星更靠近地球and it was still about 200 million kilometers away.但还是有约两百万公里的距离We might as well just go straight to Mars at that point!照那样我们还不如直接去火星吧！Even if a comet did come by Earth,即使彗星确实经过地球we assume that its trajectory is towards Mars,我们也断定它的轨道是朝着火星的and we ignore that it would likely be in its more gassy, less-solid state,并且我们忽略了它可能更多的是气体而非固态物质you’d still have to keep yourself alive on the comet.你还要在彗星上生存下去I guess if it’s only a day or so then food and water would be less of an issue我猜如果只是一天左右那食物和水就不是问题了since the aliens would definitely feed you once we got there,因为一旦我们到了那里外星人肯定会伺候我们的but you’d still have to worry about oxygen and protecting your self from space.但你仍要担心氧气并且保护自己远离太空You would need about 0.84 kilograms of oxygen a day,你每天约需0.84公斤的氧气so you better grab a spacesuit and take a big breath before jumping on the comet.所以跳上彗星前你最好穿上宇航服深吸一口气So yeah, using comets as a means of space travel is probably not that viable in the end.所以利用彗星进行太空旅行或许并不可行Sometimes I like doing these thought experiments, you know,有时我喜欢做这些思维实验and then realizing that they can’t work.然后意识到不可能实现But it’s still interesting!仍然它仍很有趣！That’s how we learn people!这也是咱认识人类的方法！So do you have any questions about space that you want me to answer.你有关于太空的疑问想要我解答？Any planets that we should cover next?接下来我们要讲哪些行星？Let me know right now in the comment section below!请立刻在下方评论区告诉我吧！Curious to know what would happen if you were trapped on the international space station?我很好奇如果你被困在国际空间站会发生什么？We teamed up with our friend William Osman to answer that question.我们会与我们的朋友William Osman一起为你解答ISS actually gets its power from solar arrays made up of thousands of solar cells.国际空间站的能量来自上万个太阳能电池组成的阵列These arrays can efficiently covert solar energy into electrical power. 这些阵列可以有效地将太阳能转换成电能Typically producing more power than the station needs at one time. 通常在同一时间产生超出所需的电力（二）饮水鸟蕴含的工程学原理The Engineering of the Drinking BirdThis toy has fascinated me since childhood.我从小就对这个玩具着迷To me its motion is almost hypnotic.对我来说它的运动就像是催眠Here’s how it operates.它是这样运转的Wet the bird beak thoroughly with room temperature water.将鸟喙完全浸透在室温的水中The opaque container makes it looked chilled,不透明容器使它看起来冷淬了but it isn’t…其实并没有Then stand it upright…然后让它直立It will take a few seconds for it to start drinking…它要等几秒钟后才开始喝水Notice that all of the action right now takes place in the stem here 注意现在所有的运动都发生在躯干这里As l speed up the action当我快进这个过程you see liquid rising and the bird rocking back and forth.可以看见液面上升饮水鸟开始前后摇摆If I return to normal speed,如果调回常速播放you can see the bird slowly …可以看到饮水鸟慢慢地very, very slowly ….非常非常慢地Rock forward…向前摆动Until it takes a drink,直到它喝到了水which it will do again and again.然后一遍又一遍地重复此过程In this video I’ll detail the bird’s clever engineering design,在本视频中我将详述这只鸟精妙的工程设计explain how it uses thermodynamics,阐明它是如何运用热力学知识and link its action to some of the greatest将其运动与一些工程师创造的and most impactful devices created by engineers.伟大且影响深远的装置联系起来的This toy has long history,这个玩历史悠久but its current incarnation is due to Miles V. Sullivan—它的当前形态是由贝尔实验室一名科学家a scientist at Bell Labs.Miles V. Sullivan创造的He specialized in methods of manufacturing semiconductors,他专精于研究制造半导体的方法but as a sideline invented toys.发明玩具是他的副业Its reported that this bird delighted U.S. President Herbert Hoover,据说这只饮水鸟深得美国总统赫伯特·胡佛喜爱an engineer who failed to figure out how it worked,作为一名工程师他没搞懂它的工作原理and it also defeated the great scientist Albert Einstein,而且它还难倒了伟大的科学家艾尔伯特·爱因斯坦who spent three and half months studying it.爱因斯坦花了三个半月来研究它It’s reported that he refused to take the bird apart.据报道他拒绝把这只鸟拆开With the benefit of hindsight,有了后见之明let’s start by exploring how it works让我们从探索它的工作原理and examining the key engineering design aspects.以及检查关键的工程设计方面开始First, let’s ask is the water ornamental or essential?首先要问的是水是装饰品还是必需品？At first the bird acts just as if the water were still there.最初饮水鸟的行为好像水还在那里一样Now let’s speed up the bird’s motion我们快进饮水鸟的动作you see at 15 minutes it is still drinking.可以看见过了15分钟它仍在喝水At 30 still drinking.30分钟还在喝水45 minutes still drinking.45分钟依然还在喝水60 minutes still drinking.60分钟还在喝水75 minutes still drinking.75分钟仍然还在喝水And five or ten minutes later,又过了5到10分钟后at eighty or eight-five minutes it takes its last drink.约在80到85分钟它喝了最后一次水The liquid still rises a bit,虽然液面上升了一点but it never rises enough to make the bird tip over,但它从没上升到足够使鸟翻倒的高度which shows that the motion is not perpetual说明这个运动不是永恒的—as long as there is water, the bird keeps drinking.只要有水鸟就一直喝水Let’s look inside the bird来看看饮水鸟的内部to get an idea of how it works.了解它的工作原理Underneath the bird’s hat, beak and fabric covering lies a glass bulb 在鸟帽鸟嘴和织物覆盖物下面有一个玻璃泡smaller than the bulb at the base, and also rounder.它比底部的玻璃泡小也更圆Now, watch as I put a few drops of isopropyl alcohol on the bulb to cool it.现在我滴几滴异丙醇在玻璃泡上使它降温The liquid rapidly rises to the head,里面的液体快速上升到头部this changes the bird’s center of gravity这改变了饮水鸟的重心so that it will tilt forward.使它向前倾斜The head now fills with liquid and then …现在头部充满了液体接下来……there…你看…it …drinks.它喝水了It becomes upright and the liquid drains from the head.它直立后液体从头部排出Liquid rises again to the head and…液体再一次上升到头部……the bird drinks again.饮水鸟再一次喝水This cycle repeats until all of the isopropyl alcohol on the bird ’s head evaporates.这个过程循环往复直到鸟头上的异丙醇都蒸发掉Why does the liquid rise?为什么液面会上升呢？The place to begin is with the bird’s manufacture.我们从饮水鸟的制造说起The bird is filled through this “tap ”—a small pipe built into the head —通过装在头部里的小管子即龙头with methylene chloride dyed red, which is then frozen,向鸟内装入冷冻的染成红色的二氯甲烷a vacuum applied to evacuate the air,抽走空气形成真空the tap sealed ( and of course, later hidden by the bird’s hat )…把龙头密封(当然后来被鸟帽盖住了)And then the methylene chloride melts:之后二氯甲烷融化It turns to liquid and then some of it evaporates（turns into vapor）.转变为液态其中部分二氯甲烷蒸发(变成蒸汽)The key to the bird’s operation is饮水鸟运转的关键就在于that the vapor in the head and in the base are separated by the liquid in the base.头部和底部的气体被底部的液体所隔离It’s hard to see,这很难看清楚but the tube extends into the base, nearly reaching the bottom.不过管子延伸到底部几乎接触到底面This separates the vapor in base and the vapor in the tube使得底部和管中的气体隔离……and …of course, the head.当然还有头部的气体So, at rest the pressure in these two spaces are equal,在静止状态这两个空间的压强相等but when the bird’s beak is wet,但当鸟喙湿润时the temperature falls鸟喙温度下降and as I’ll explain in a moment the pressure in the head drops头部的压强下降这个我稍后会解释below that in the base and the liquid rises.降到低于底部的压强然后液面上升Of course this liquid in the head causes the bird to…tilt forward, to drink …自然头部的液体导致饮水鸟向前倾斜喝水and when it drinks,当它喝水时the vapor in the head and the base are connected,头部和底部的蒸汽连通the pressures is nearly equalize两端压强几乎相等—a slug of vapor rises to the top and some liquid drains from the head一股蒸汽上升到头部迫使部分液体流出and then the cycle repeats.然后循环重复To see the pressure equalize为了看到压强平衡过程l will slow down the bird as I tilt it forward.我会慢一点倾斜饮水鸟Right now the head is half full.现在头部已经半满了When I tilt it you see a slug of vapor go from bottom to top.当它倾斜时可以看见一股蒸汽从底部升到顶部I’ve tilted it far enough forward我把它倾斜得够多that the liquid in the head is below the top of the tube以至于头部的液面低于管子的顶端and the liquid in the base is below the section of the tube that almost reaches the bottom of the bird.同时底部液面也低于几乎触底的管子底端This allows the pressure to equalize,这样头部和底部的压强相等and as the bird becomes upright而当饮水鸟站起来时the liquid returns to the base before the cycle starts again.液体会在下一次循环开始之前返回到底部In operation it doesn’t tilt quite this far forward实际运转时它不会向前倾斜这么多and so the pressures don’t fully equalize.因此压强不会完全平衡Why, though, does the pressure in the head drop as the temperature falls?那么头部压强为何会随着温度下降而下降呢？You can see the answer if I shoot cool, compressed gas across the bird’s head.你看我向头部射低温压缩气体就知道答案了As the cool gas strikes,遇到低温气体时you see liquid condensing inside the head;头部内壁出现了冷凝的液体and, as you see on the left,正如你在左图看到的this causes the liquid in the base to rise.这导致底部的液面上升The cool gas withdraws energy as heat from the head,低温气体带走头部的热量causing some of the methylene chloride vapor inside to condense –to turn into a liquid.导致头部部分二氯甲烷气体冷凝成液体This decreases dramatically the amount of vapor in the head.这大大减少了头部的气体体积Liquid is 1,000 times more dense than vapor.液体的密度是气体的1000倍This in turn lowers the pressure in the head and causes the liquid to rise.结果降低了头部的压强使液面上升I used compressed gas to cool the head我用压缩气体给头部降温because I can control the amount of cooling;因为我可以控制降温的程度the bird, though, cools its head by “drinking.”然而饮水鸟通过喝水来降温The head is wrapped in fabric that absorbs water.其头部包裹在吸水的织物中As I put drops on its beak当我把水滴在鸟喙上you can see the water beads up at first…一开始你可以看到水珠……and then saturates the fabric and spreads rapidly across the bird’s face.然后水珠浸透织物并迅速扩散到鸟的整个面部On the right side you can see it creeping to back of the head.从右边看可以看到水渍浸到了后脑勺If I now turn the bird around,如果我现在把鸟转过来you can see that the water has spread to the back.可以看到水已经蔓延到后面As I continue adding drops on the beak如果我继续往鸟喙上滴水the saturated area on the back increases.头背处渗水区域扩大When this water evaporates into the air, it removes energy from the bulb as heat当水蒸发到空气中带走了头部的热量you feel this effect every time you step out of the shower,每次你洗完澡都会有这种感受the evaporating water withdraws energy as heat and chills you.蒸发的水带走热量让你感到冷飕飕的This evaporation, this withdrawal of heat, lowers the temperature 蒸发吸热降低了头部的温度and begins the condensation of the vapor, which starts the cycle 蒸汽冷凝启动循环as I showed you with the cool, compressed gas.就像我之前用低温压缩气体做的演示一样As long as the head is wet and heat is withdrawn from it,只要头部保持潮湿而且有热量带走the bird will always “drink, ”饮水鸟将一直“喝水”but if you were to operate the bird in humid air,但如果你把饮水鸟放在潮湿的环境it would slow down, because little water would evaporate,它就会减速喝水因为很少有水分蒸发and if the air were at 100 % humidity the bird would stop如果空气湿度是100% 饮水鸟将停止喝水because no water would evaporate at all.因为根本没有水蒸发Now, to make this dramatic condensation happen现在为了达到明显的冷凝效果when the temperature is lowered just slightly当温度只稍微降低时the evaporating water lowers the temperature by only about three-tenths of a degree水的蒸发只降低了0.3 度the bird’s designer choose a highly volatile liquid.饮水鸟的设计者选择了一种极易挥发的液体This means one whose boiling point is near ambient temperature这就需要这种液体的沸点接近室温because for small changes in temperature因为即使温度轻微变化there is a large change from vapor to liquid从气态至液态的变化也是巨大的and so the variation of pressure is large.从而引起压强的巨大变化Watch what happens as I “heat ”the base of the bird with my hand.观察我用手加热饮水鸟的底部时会怎么样You see the liquid level in the base dropping,可以看到底部的液面在下降that’s because energy from my hand is converting some of the liquid into vapor,这是由于手的热量使部分液体转化成气体which increases the pressure in this region…增大了这个区域的压强and that causes the liquid to rise to the head.从而使液体上升到头部Eventually I heat the vapor so much that it shoots up the stem.最终我把蒸汽加热到从管子中冒出来Now watch as I place my hand around the head.现在看我把手放在头部Heat from my hand converts liquid to vapor,手上的热量将液体转化为蒸汽which increases the pressure从而增大了压强and forces the liquid back to the base.并迫使液体回到底部To test this explanation of the bird’s operation,为了验证这个饮水鸟运转的解释let’s activate the bird in different ways.让我们用不同方式来触发饮水鸟As I noted it is the temperature difference between its top and bottom我说过是它顶部和底部的温差that drives liquid to rise to the head.驱使液体上升至头部So, let’s see what happens if I point a light at the base of the bird,那么我们看看对底部进行光照会怎么样which I’ve painted black我把饮水鸟的底部涂成了黑色so it will absorb the energy from the light better.这样它能更好地吸收光能As I heat the base of the bird,当我给饮水鸟底部加热时the liquid rises, as before but …液体像之前一样上升但是……五倍速播放the bird tips backwards.饮水鸟向后倾斜The wet nose tilted the center of gravity……湿润的鼻子倾斜了饮水鸟的重心……and so I added some modelling clay to the nose于是我在鸟鼻子上加了些粘土to get the bird to tilt forward.好让鸟向前倾斜And now when I turn on the light the liquid rises,现在当我打开灯光液体上升the birds drinks as if there were liquid in front of it until…鸟儿就像面前有水一样喝水直到……I turn the light off我把灯关掉and the bird drinks for a little bit longer until eventually…这只鸟再坚持了一会儿直到最终……it comes to rest.它停了下来Next, let’s see what happens if we use this: Whiskey.接下来让我们看看用这个会怎么样：威士忌Again, thoroughly wet the bird’s beak with the liquid…再次用液体浸润鸟喙……stand it upright …让它直立……and then we see again the liquid rising in the bird …然后我们又看到饮水鸟体内的液面上升and then …it drinks.然后……它在喝水We can also now understand why the bird’s rate of drinking differs 我们现在也能理解在三种不同的刺激下among the three methods I used to “activate ”the bird:为什么饮水鸟的喝水频率不同了a heat lamp, whiskey and water.加热灯威士忌和水三种刺激Roughly, heat bird takes three drinks for every one of the water bird,大致上饮水鸟每喝一次水受热鸟喝三次the whiskey bird takes two for every drink of the water bird.而饮水鸟每喝一次饮酒鸟喝两次The reason the bird drinks whiskey faster than water is之所以饮酒鸟比饮水鸟快because the rate of evaporation of the alcohol is greater than that of water.是因为相对于水酒精更易挥发This means that heat is withdrawn faster from the head也就是说头部的热量散失更快and so more vapor condenses in a shorter amount of time,短时间内冷凝的蒸气更多which accelerates the pressure difference.从而加速扩大压差The heat lamp causes the greatest difference of all,加热灯导致的压差最大which highlights how an engineer thinks about this bird.这重点表明了工程师对饮水鸟的想法To an engineer this bird is a heat engine.对工程师来说饮水鸟是一个热机A heat engine turns heat differences into work —mechanical motion.热机将热能转化为功——机械运动To see that recall that when the bird is just about to drink回想一下当鸟正要喝水时that its head is at a lower temperature than its base,它的头部温度比底部的低which is at ambient temperature.底部温度就是环境温度Then when it “drinks ”, the pressure in the head and base start to equalize,当它“喝水”时头部和底部的压强开始平衡so liquid returns to the base,于是液体回到底部but the overall temperature of the bird但是现在饮水鸟的整体温度is now just a little below ambient temperature.只是稍低于环境温度When it return to upright, the base draws in energy as

1科教科普类1、Australia leads the world in its number of resident poisonous spiders as well as the strengthof their toxicity( 毒性 ). However,of almost 9,800 species most are perfectly harmless andinteresting.Spider diversity is broad and many fascinating species occur here that range from the large tothe tiny and hardly noticed, and from the dullest black to the strangely shaped.Spiders can be roughly classified according to the strategies( 策略) they use for feeding.Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to comealong before grabbing it. Following them were spiders which actively wandered looking forfood and which caught it by chasing it down. The evolution of flying insects makes spiders evolvenew ways of catching food which couldn’ t be chased and so the earliest air web weavers arose.Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs andsmall birds. The Golden Orb Spider also feeds on small birds.A spider periodically sheds( 蜕皮 ;脱落 ) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching itsfinal adult stage.Usually, once male spiders have mated, they die shortly after. But, even in death, Redbackmales often serve a purpose. The already pregnant Redback females always kill their lover and,in most cases, also eat them. This provides them with a small reproductive advantage.Allowing spiders to take up places around houses can be beneficial in that they catchother annoying insects such as mosquitoes and flies.Rest assured that while you might see some large spiders, and perhaps even some poisonousones, a good rule is to look and admire but don't touch any spider you find. Even those withoutpoison could still have a nasty bite.1.Different families of spiders are identified themselves by ______.A.their physical characterB.their ways of getting foodC.the strength of their toxicityD.their effect on the environment1A.Spiders that chase down insects for food.B.Spiders that wait for the insects to come along.C.Spiders that can weave webs to catch flying insects.D.Spiders that actively go out to look for insects as food.3.If a spider stays on the wall of your house, you______. ’ d betterA.kill itB.feed itC.let it beD.chase it out4.What is the passage mainly talking about?A.A brief introduction of spiders.B.The evolution process of spiders.C.Living harmoniously with spiders.D.The living and feeing habits of spiders.2、Many people believe that you lose the ability to learn new languages as you get older.Language experts,however,will tell you that you’ re never too old to learn a new language. As youget older, it can be more difficult to learn a new language,though.Children and adults learn new languages in different ways. For children, language is their life.They study for thousands of hours every year. Because they need to learn language to became partof their communities.Adults,on the other hand,are already part of a language community. Learninga new language means becoming part of another language community,and adults rarely get thechance to practice as much as young children do.Moreover.children leaning a new language are expected to make mistakes. This gives themfreedom when learning to be daring and confident Adults,however,often feel pressured to beperfect when learning a new language.This can discourage many people and make it even harderto learn a new language.When young children learn a new language,they come to see various languages as a“ normal”part of society.This mindset( 思维模式 ) helps them embrace learning a new language withoutSo if you want to learn a new language,go f or it! It’ s never too late to learn a new language. If you're older,it may take more work,but it can be done.If you're a young child,though,now is thetime to step out and learn a new language!1.By“ Language is their life” ,the author means that children.A.can't live without languageB.lead a happy life every dayC.practice a new language a lotD.are taken good care of adults2.What may make it hard for the old people to learn a new language!A.They are afraid of being laughed at.B.They usually have too many interests.C.They think making mistakes is natural.D.They always make all kinds of mistakes.3.Which of the following shows the difference between children and adults in learning newlanguage?A.The behaviors they have.B.The learning attitudes.C.The future plans they have made.D.The materials they are using.4.According to the author,a new language.A.can never be learned by the old peopleB.can be grasped by the people easilyC.can be understood only by the old peopleD.can learned by both the old and the young3、 Kids and teens are often dismissive of praise from their parents. I am sure that parents outthere can relate to this, as we all have been told at one time or another by one or several of ourkids,“ Stop it, Mom’’. or even,“ You’ re just saying that because you are my parents and you have to say that. " I can assure you, though, that they are listening. They will probably not thank you forthis praise until they are in their twenties, but don't let that stop you from praising them duringtheir childhood and teen years. Just be careful how you praise them. A little praise may go a long way —especially if it is the right kind of praise.It appears that the way to go is to praise their efforts according to a study by Brummelman, of Utrecht University in the Netherlands and colleagues. These researchers concluded that kids should be praised primarily for their efforts, rather than for their personal characteristics, becauseif they are praised for effort, then a poor performance is more likely to be seen as a glitch( 小故障 ), rather than a valid reflection of who they are as individuals.Let ’ s think about this together. If you are a teenager or a child of any age and are constantlytold how brilliant you are, then when you do poorly on a test or a few tests, you may feel like you have suddenly lost your status as brilliant and may now feel ashamed that you are merely averageor even dumb. If you are a girl who is constantly being told how beautiful you are, then on a day when you don’t look or feel so good, you may decide that you are unattractive. This is the problem that develops when we are praising our kids for global personality characteristics that theycan't always live up to.1.According to the passage, which of the following statements is the right kind of praise?A.You are a great artist.B.You are very intelligent.C.Wow, you have a special gift for music.D.Your painting has indeed improved due to your efforts.2.Which of the following statements is TRUE according to the passage?A.All the children should be praised.B.There ’ s no need to praise kids and teens.C.Praise should be beyond children’ s expectations.D.Teens often pay no attention to their parents’ praise.3.The underlined word“ dumb” in theagraphlastparcan be replaced by _________.A.stupidB.uniqueC.curiousD.honestA.why to praise kids and teensB.how to praise kids and teensC.different ways to praise kids and teensD.the importance of praising kids4、 Scientists, psychologists and English academics at Liverpool University have found thatreading the works of the classical writers like Shakespeare and Wordsworth has a great effect onthe mind, catches the reader’ s attentionriggersandmoments of self-examination.Using a special machine, they monitored the brain activity of 30 volunteers as they read worksby William Shakespeare, William Wordsworth, T.S. Eliot and others.In the first part of the research, the brain activity of 30 volunteers was monitored as they readpassages from Shakespeare’ s plays, including King Lear, Othello, Coriolanus and Macbeth, andagain as they read the text rewritten in a simpler form or modern language.While reading the common texts, normal levels of electrical activity were shown in their brains.When they read the works of Shakespeare, however, the levels of activity jumped because ofhis use of words which were unfamiliar to them. The result of the test showed that the morechallenging passages cause a greater degree of electrical activity in the brain than thecommon ones.Scientists went on to study the brain activity as it responded to each word and recorded how itlit up as the readers came across unusual words, surprising phrases or difficult sentences in theclassical works. As a result, this lightening up process of the mind lasted longer than that whenvolunteers read common texts, encouraging further reading.The research also found that reading poetry especially increases activity in the righthemisphere(半球 ) of the brain, an area connected with“ autobiographical memory” , driving the readers to think carefully about their own experiences based on what they have read. Theacademics said this meant the classical works of literature are more useful than self-help books.Philip Davis, an English professor who has worked on the study in the university’ s mag resonance center, announced this week:“ Classical literature acts-boosterlikearockettothe brain,which provides extra power for the brain. You may never imagine how powerful it is. Theresearch shows such kind of literature can create new thoughts and connections in the young andthe old.”1.The underlined word“ trigger” in Paragraph 1 is closest in meaning to“ ______”.A.depends onB.picks upC.sets offD.changes into2.Which of the following is NOT true about reading classical literature?A.It makes readers ’ brain more active than reading common texts.B.It makes readers ’ electrical activity of brain return to normal.C.It ’ s helpful for readers to come up with new ideas.D.It ’ s an activity that is suitable for people of all ages.3.From the research, we can learn that ______.A.the readers prefer Shakespeare ’ s works to the other writers ’ worksB.the words of classical works make it hard for volunteers to read furtherC.reading classical works produces a good and long-lasting effect on the mindD.poetry increases left-brain activity more than other literary forms4.What does the author mainly tell us in this passage?A.Shakespeare plays’s deserve to be read.mon books are unpopular anymore.C.Poetry is best for developing people ’ s brain.D.Classical works help the brain develop better.5、 Do parents have a constitutional right to homeschool their children? No, according to aCalifornia District Court judge, who recently ruled that a child must be schooled "by a personholding a valid state teaching credential ( 文凭 )for the grade being ta ught ”.What started as a Los Angeles County child welfare case involving one specific family hasgone into proceedings ( 诉讼 ) that have actually put on trial the very nature of what constitutes asound education.“ For decades we’ ve been happily ling,homeschooandthen this comes upgiven homeschooling parents the freedom to choose the kind of education they want for theirchild.This particular family in Los Angeles had enrolled their children in a private schoolindependent study program not in their home. In response to abuse charges against the family, thechildren were enrolled in public schools. The parents stated they had a constitutional right tohomeschool on religious grounds; that's when the court ruling was issued. However, Griffith saysif the ruling ends up affecting anyone, it will mainly be those who also enroll their children inoff- site homeschooling.“ This won't-reachingbefar for homeschooling parents."That's how organizations like the Homeschool Association of California (HSC) would like tokeep it, anyway, and they've hired a team of lawyers to limit the impact of the case. Griffith saysthe legal team for HSC is trying to establish that while this ruling may indeed be necessary for thisparticular family, it should not set a precedent( 先例 ) for all.What does this case really mean for homeschooling families nationwide? According to DarrenA. Jones, this decision is certain to affect homeschooling on a national scale. Jones claims that it iscommon for state courts to look to other states’ rulings for assistance in deciding issues where no precedent exists.“ A poor legal decision in California could become part of a trend acrosse thnation.’’1.In Griffith’ s opinion, ________.A.parents don’ t have a right to homeschool their childrenB.a child must be schooled by an expert with a credentialC.homeschooling should be forbidden in the whole countryD.it is understandable for parents to homeschool their children2.The underlined word“ this” in Para. 2 refers to the fact that.A.parents happily homeschool their childrenB.parents don’ t have a right to homeschool their childrenC.a child must be schooled by a person with a teaching credentialD.a Los Angeles County child welfare case involves a special family3.Why were the particular family’ s children enrolled in public schools?A.To avoid the abuse charges against them.C.To break away from their parents.D.To cooperate with the expert’ s jobs.4.What ’ s the author’ s attitude towards whether parents have a right to homeschool their children?A.Supportive.B.Sympatric.C.Negative.D.Objective.6、Summer shouldn't mean taking a break from learning, especially reading. Studies show thatmost students experience a loss of reading skills over the summer months, but children whocontinue to read actually gain skills. So efforts should be made during the summer to helpchildren keep reading skills, practice reading and read for enjoyment.Parents should remember that children need free time in the summer to relax and enjoy thepleasures of childhood. So summer reading should be fun. Following are a few tips to makereading enjoyable for your children this summer:Read aloud together with your child every day.Make it fun by reading outdoors on the front steps, patio, at the beach or park. Also, let yourchildren read to you.Set a good example!Keep lots of reading material around the house. Turn off the TV and have each person readhis or her book, including Mom and Dad.Read the same book your child is reading and discuss it.This is the way to develop habits of the mind and build capacity(能力) for thought and insight.Let kids choose what they want to read, and don turn your nose’upt at popular fiction. It willonly discourage the reading habit.Subscribe, in your child’ s name, to magazines.Encourage older children to read the newspaper and current events magazines, to keep up the reading habit over the summer and develop vocabulary. Ask them what they think about whatthey ’ ve read, and listen to what they say.1.Parents must help children read during the summer because ________.A.the summer holiday is too long a time for themB.reading is a kind of relaxation for childrenC.some of the reading skills may be lost if they stop readingD.children can enjoy the pleasure of childhood2.What does the underlined phrase "turn your nose up at” probably mean?A.Get interested in.B.Show one ’ s dislike for.C.Think highly of.D.Lose interest in.3.In oder to build children's capacity for thought and insight, parents should ______.A.subscribe to magazines in the child’ s nameB.read the same book the child is reading and discuss itC.let children choose what they want to readD.turn off the TV4.What does the passage mainly tell about?A.Some summer reading tips for parents.B.Some useful advice on reading for children.C.What kinds of books to read in summer.D.How to teach children to read.7、 Have you got the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware of. In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.Now scientists say there exist seven basic learning styles.·Linguistic: These people learn through listening, reading, speaking and writing.·Logical: These people learn with formula (公式) and principles (原理).·Visual: These people learn by seeing what they are studying.·Musical: These people learn well when information is presented through music.·Kinesthetic: These people learn from movement and physical activities.·Intrapersonal: These people learn best by linking new information directly with their own experiences.·Interpersonal: These people learn well by working with others.Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.1.From the passage, we know that our brains ______.A.deal with the information in different waysB.send out the information in the same wayanize information with our bodiesD.gather information in the same way2.A visual learner usually learns _____.A.through listening and speakingB.by seeing what he is learningC.from movement and physical activitiesD.by linking new information with his experience3.A musical learner will find it easy to learn ______.A.with formulas and principlesB.by working with othersC.through reading and writingD.through music he hearsA.learn more successfullyB.gather more informationC.understand more quicklyD.exchange information better8、 In 2015 a paper published in a science magazine reported on the personality types of peopleliving in various London districts. Extroverts ( 外向的人 ), the researchers who wrote it haddiscovered, favored Richmond. Those who were most open to experience gathered in Hackney.People in Barnet scored lower than average on emotional stability.What this study did not address was whether someone’ s home range reflects their personality traits or imposes them. In other words, is what is going on“ nature培育”)? orHowever,“nurture” (in a piece of research just published, Dr. Holtmann of Otago University, in New Zealand, and hiscolleagues have filled that gap — at least, they have filled it for dunnocks.The dunnock is a European bird. It has, though, been introduced to New Zealand and itspopulation has boomed there. It is a well-studied species, and, in particular, some beingmeasurably bolder (更大胆的 ) and more tolerant of potential threats, such as nearby humanbeings, than others. The team’ s research area was the Botanic Garden in Dunedin. This is open tothe public, but some areas are more frequented by visitors than others. Dunnocks have smallterritories, so it was possible to measure the amount of human disturbance in a given territory withreasonable precision. And, by wrapping each of the dunnocks in the garden with colour-codedbands it was possible to identify individuals by sight. Altogether, the researchers looked at 99 ofthem.They worked out a bird’ s level of threat tolerance by the simple method of walking towards it,and then measuring how close one could get before the bird flew away. They did this several times foreach bird every breeding season, and repeated the process over the course of three seasons.A particular bird’ s flight distance (ie, how closely it could be approached before it departed)was, they found, consistent within a breeding season. From season to season most birds got a littlebolder— probably as they learnt more about the world and what they could safely get away with.But this increase in boldness with age was small compared with the different starting points of boldthat, on average, birds’ flight distances were inversely correlated负相关) (with the level of human disturbance in their territories. This was a consequence of disturbed territories being settledby bold birds, and undisturbed territories by shy ones.In the case of dunnocks, then, nature wins over nurture. Dr. Holtmann was able to show that personalities match circumstances, rather than being created by them. Dunnocks can recognizewhich places suit them best, and choose to settle in them shortly after they are fully fledged (羽翼丰满 ). Most likely, that is happening in London districts, too.1.What does the underlined words “ that gap ” in the second paragraph refer to?A.What the paper published in 2015 failed to handle.B.Why extroverts favour certain areas in London district.C.How Dr. Holtmann involved dunnocks in his study.D.What the former and latter study have in common.2.From Paragraph 3, we can know that dunnocks ________.A.are native to New ZealandB.have distinct personalitiesC.are bolder than human beingsD.can be easily identified by its color3.What conclusion did Dr. Holtmann draw from his study?A.It ’ s nurture rather than nature that matters in the case of dunnocks ’ behaviour.B.Birds ’ flight distances were in proportion to human disturbance in their territories.C.Dunnocks choose their habitats wisely in the first place rather than adapt to them.D.Bold birds and shy birds alike settle in undisturbed territories in the botanic garden.4.What is the author ’ s purpose in writingepassage?thA.To argue that circumstances cultivate certain personalities.B.To entertain readers with some funny facts about dunnocks.C.To present the finding of a scientific research about dunnocks.D.To confirm the assumption that personalities match circumstances.答案以及解析1答案及解析：答案： 1.B; 2.C; 3.C; 4.A解析： 1.细节理解题。
2019届高三英语科普文和故事类阅读理解含答案
2019届高三英语科普文和故事类阅读理解含答案科普文1Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.54. Acco rding to the context, what’s the meaning of the word “speculation” in paragraph 2?A. The act of discussing something with a group of people.B. The act of studying and researching.C. The act of guessing without knowing all the facts about something.D. The acting of writing letters to a certain organization.55. Why did people keep the idea of terraforming to themselves in the past?A. They thought no one else would show interest in the idea.B. They gradually came to find the idea crazy.C. They thought the idea would never come true.D. They had few resources for further study on this topic.56. Which is NOT the reason to support the study of terraforming?A. Even if we don’t succeed in terraforming, such study may help us to better understandtechnologies such as climate and weather control.B. Such study may explore a new direction of development for human beings.C. Such study may enable us to find the lives on other planets.D. As the resources on Earth are being drained, it’s very urgent to study how to migrate (迁移) to other planets.57. What’s the main idea of the article?A. It’s highly possible that terraforming other planets will come true so we should increaseinvesting in this program.B. Even if the idea of terraforming other planets may take centuries to realize, we have manyreasons to support such studies.C. Terraforming other planets is the best option for human being’s future.D. More and more people are taking planetary engineering as their occupation.54-57 CADB科普文2Cooking Kills Four Million People a YearPolluted airborne particles(大气悬浮颗粒) kill 7 million people a year, reports the World Health Organization.That news may not come as a surprise to anyone who has seen images of chimneys in Beijing, Delhi or Mexico. But those factories－or even the jammed roadways of modern cities－are not the biggest killer. Each year, some 4.3 million people die earlier than they should because of polluted air inside their homes, says the WHO.What's causing the air inside people's homes to be so poisonous that it kills around 11,000 people a day? Stoves. “Having an open fire in your kitchen is like burning 400 cigarettes an hour.”says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013.Not all stoves cause this kind of harm. The ones Smith's talking about are those that the 3 billion people in the developing world use for heat and cooking, which burn solid fuels such as wood, coal, or crop waste instead of gas. The smoke from those fires produces harmful fine particles and carbon monoxide into homes. Poor ventilation then prevents that smoke from escaping, raising fine particle levels 100 times higher than the limits that the WHO considers acceptable.Breathing this air day in day out eventually causes a lot of diseases: more than a third of the 4.3 million die of a stroke, while a quarter die of heart disease. And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves.Exposure tends to be extremely harmful for the people who spend the most time around the fire－usually women and young children. In fact, the WHO reports that household air pollution almost doubles the risk for childhood lung disease.12. According to Kirk Smith's research,________.A. factories are the biggest killer worldwide nowadaysB. burning 400 cigarettes an hour is extremely dangerousC. household air pollution from cooking is surprisingly harmfulD. some 4.3 million people die earlier each year than they should13. What should be the deadly killer in a household kitchen?A. Solid fuels.B. Coal stoves.C. Poor gas.D. Cooking smoke.14. The underlined word “ventilation” in Paragraph 4 probably means ________.A. airingB. cookingC. burningD. cooling15. The author intends to tell people ________.A. how to avoid polluted air in their homesB. to stop cooking in the household kitchenC. to guard against household pollution from cookingD. how to prevent childhood lung diseases in household12. 【答案】C【解析】细节理解题。
专题05 阅读理解科普类-2019年高考英语母题题源系列(解析版)
专题05 阅读理解（科普类）【母题来源一】【2019·全国卷I，C】As data and identity theft becomes more and more common, the market is growing for biometric(生物测量)technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates.

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。

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.

Plates and cups are made of fresh banana leaves.B. Remya's washing machine can also keep people fit.C. David Cohen is a middle school student from India.D. 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.

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.

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.

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. Get yourself together.This might sound like silly advice, but it's actually the most important. When you fear, you may lose con trol over your thoughts and actions Even if you try to study, perhaps you won’t get anything in your head.Enjoy enough sleep.It's unbelievable many students have little sleep each night. That’s not something to be proud of, especially if you're sleeping so little and still failing to do all the things Sleep isn't for the weak, but for the wise. Your brain needs enough rest. After a good night's sleep, you'll perform much better in the morning.Don’t fear.Once the test paper is in front of you don't be afraid. Take a deep breath and start the exam with confidence(信心).

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. What is the space elevator's purpose in accepting passengers as soon as possible?A. To ship cargo to space.B. To get in the competition between space-lines.C. 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。
2019年高考英语真题分类汇编：专题16-科普类说明文(含答案解析)
专题十六阅读理解之科普类说明文1.【2015·湖北卷】DThe oddness of life in space never quite goes away. Here are some examples.First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks your’re falling . Mea nwhile your eyes are telling you you’re standing straight. That can be annoying—that’s why some people feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to makea round-trip to Mars.63.What is the major challenge to astronauts when they sleep in space?A. Deciding on a proper sleep positionB. Choosing a comfortable sleeping bagC. Seeking a way to fall asleep quicklyD. Finding a right time to go to sleep.64.The astronauts will suffer from a carbon-dioxide headache when _____.A. the y circle around on their bikesB. they use microcomputers without a stopC. they exercise in one place for a long timeD. they watch a movie while pedaling65.Some astronauts feel sick on the station during the first few days because _____.A. their senses stop workingB. they have to stand up straightC. they float out of their seats unexpectedlyD. whether they are able to go back to the station66.One of the NASA’s major concerns about astronauts is _____.A. how much exercise they do on the stationB. how they can remain healthy for long in spaceC. whether they can recover after returning homeD. whether they are able to go back to the station【解析】试题分析：这是一篇说明文。

Mae JemisonImagine you are lying on your back, strapped into a chair, with your knees bent in front of you. You feel your heart beating with excitement as you hear a voice on the earphone inside your helmet counting down slowly,” Three, two, one,” Then, beneath you, a deep rumble start as rocket fuel ignites in the huge engines. You① feel a lurch as the docking mechanisms let go, and your rocket begins to rise. This is the moment Mae Jemison has been waiting and working for since 1987. The firstAfrican-American female astronaut-in-training at the National Aeronautics and Space②Administration (NASA) , Jemison is scheduled to “fly” in September 1992. She is to serve as a specialist on Spacelab—J, a joint Japanese—American research project.Mae Jemison was thirty-three when she was selected for NASA’s astronaut training program. Astronaut candidates must have science degree. They must be fit and healthy with normal blood pressure and good eyesight. They must stand between five feet and six feet four inches tall. They must complete a one-year training program that includes water-survival lessons and weightless walks in a huge antigravity tank. On the 1991 mission, astronaut Jemison says that her “responsibility are to be familiar with the shuttle and how it operates, to do the experiments once you get③ into orbit, to help launch the payloads or satellites, and also to do extra-vehicular activities, or space walks.”How did Mae Jemison grow up to become such a special person? Science —especially astronomy—fascinated her from childhood.She also had a strong desire to help other people. Born in Alabama, but raised in Chicago, she studied chemical engineering and African—American culture and history at Stanford University. To help others, she decided to become a doctor. While still a medical student, she went to Cuba and Kenya on study trips, then worked in④a refugee camp in Thailand. She spent three years in West Africa as a doctor with the Peace Corps. When Dr. Jemison finally returned to the United States, she settled in California to practice medicine. And it was then that she decided to reach for the stars.Mae Jemison’s first application to NASA was not successful. Then, in 1986, the⑤Challenger space shuttle exploded, killing all aboard . NASA did not take in any new astronauts for about a year. When it finally reopened its application process, Mae Jemison was ready, and so was NASA. After being selected as a minority astronaut, Mae Jemison received a good deal of attention from newspaper and television. She explained to reporters that the space program and other fields in high technology offer promising careers for African-Americans and other minorities who study hard⑥and make the most of their opportunities .1.The first paragraph is about ______.A.how excited Mae Jemison was when she became an astronautB. how Mae Jemisonbecame an astronautC.how the people usually feel when the rocket they take begins to riseD.what Mae Jemison did after she was able to fly a rocket2.Which of the following statements is true?A.Mae Jemison had a strong desire to become famous.B.Mae Jemison was brought up in Alabama.C.Mae Jemison studied astronomy at Stanford University.D.Mae Jemison studied medicine.3.When did the Challenger space shuttle explode? A. Before Mae Jemison became a doctor.B.Shortly after Mae Jemison graduated from Stanford University.C.About a year before Mae Jemison was selected as an astronaut.D.About a year after Mae Jemison became famous all over the world.4.Mae Jemison believed that _______.A.men and women were not equalB.women were better paid than men wereC.American blacks were unable to find satisfactory jobs no matter how hard they studiedD.American blacks were able to find satisfactory jobs if they studied hard and made gooduse of their chance5.What is the attitude of the writer towards Mae Jemison’s achievements?A.JealousB.UpsetC. NegativeD. PositiveNotes:①lurch v. : To roll or pitch suddenly or erratically. 突然倾斜,突然地或者无规则地倾斜或坠落。

阅读理解(七)科技说明A[2019·原创]Many people hope to visit the White House in person some day in the future. But most people will never get a chance to go inside the White House, the famous home of the President of the United States.Luckily, there is a new app that can bring the White House to life for anyone with a smartphone equipped for computer programs.To experience this famous building, you just need your smartphone and a one-dollar bill.The new app is called 1600, which makes one think of the real street address of the White House, 1600 Pennsylvania Avenue, in Washington D.C.The 1600 app creates a small White House on your smartphone. After downloading(下载) it, you only need to point the camera on the phone at one dollar to start the experience.The dollar then changes into a three-dimensional(三维的) model of the White House before your eyes. It creates images having length, width and height. When the smartphone is moved around, the images of the building also change.The US former(前任的) President Barack Obama’s Press Secretary, Josh Earnest, provides explanation as part of the app. He provides lots of the historical information about the White House, talks about how the building is used today and describes some events held there.The app shows some of the changes on the White House grounds around the year. You can watch the Easter Egg Roll in spring and see a formal arrival(来访) ceremony for a foreign leader.What’s more, there is even a hidden surprise to catch if you touch on the Oval Office. That’s really cool!“We hope you enjoy and share this new way of having a look inside the White House,” Josh Earnest said.The new app is the latest way that the government has used technology as an educational tool. This time it gives people all over the world the chance to visit “The People’s House”.。
2019年中考英语阅读理解真题专项训练(科普知识与现代科技)
2019年中考英语阅读理解真题汇编(带详细解析过程)(名师精讲解题方法与技巧+实战训练，建议下载练习)【考点分析】阅读理解旨在考查学生阅读、理解的能力。
近几年来，中考英语题中的阅读理解材料新颖，题材丰富，考查学生综合推断能力、根据语篇猜单词意思的能力的力度加大，考查学生关注细节的能力占很大部分。
所以学生往往要么没能正确理解语篇中某些句子的意思，在细节题上丢分，要么就是对语篇的整体把握不够，在综合题或者推断题方面丢分。
那么到底怎么做好阅读理解这一题型呢？一、解题思路（一）先读问题，弄清考查要点，以便能带着问题看文章，这样会心中有数，有的放矢。
（二）快速浏览全文，掌握全貌，注意发现与问题有关的信息，如果时间紧，至少要扫视一下起首段和尾段。
再把标题和文章内容结合起来想一想，这样全文大意便清楚了。
此时，不要忙于答题。
（三）细读原文，捕捉相关信息词，掌握短文细节内容。
这是解题的关键，应特别注意以下几点：1．抓住四个"W"和一个"H"，就是边读边用铅笔做些标记，把What (事件)，When （时间），Where（地点），Why（原因），How（经过）划出来。
抓住了四个“W”和一个“H”，就抓住了文章的全貌，一些直接性的问题便可解决。
2．抓住连接词及起关键作用的副词、代词、介词、插入语等。
因为这些词具有因果，让步，递进，转折，指代，列举及承上启下等各种连接上下文的特殊功能。
这对考生分清文章层次，辨明各种关系，了解人物心理，推断作者意图，进行逻辑推理等手段来分析难点，都具有举足轻重的作用。
3．注意领会文章的寓意。
4．根据题意，初选答案。
这一步须仔细审题，领会测试要求，确定解题方法。
对那些明显的，有把握的题可以断然确定，不必把其余三个答案再作推敲而浪费时间：有些略难的题，应再查阅短文（不是重读一遍），迅速找出依据，予以排除。
常用的解题方法有如下几种：①直接解题法。
即从原文中直接找出答案。
2019届高考英语阅读理解精选细做：科教科普类
科教科普类1、Australia leads the world in its number of resident poisonous spiders as well as the strength of their toxicity(毒性). However,of almost 9,800 species most are perfectly harmless and interesting.Spider diversity is broad and many fascinating species occur here that range from the large to the tiny and hardly noticed, and from the dullest black to the strangely shaped.Spiders can be roughly classified according to the strategies(策略) they use for feeding. Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to come along before grabbing it. Following them were spiders which actively wandered looking for food and which caught it by chasing it down. The evolution of flying insects makes spiders evolve ne w ways of catching food which couldn’t be chased and so the earliest air web weavers arose.Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds.A spider periodically sheds(蜕皮;脱落) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching its final adult stage.Usually, once male spiders have mated, they die shortly after. But, even in death, Redback males often serve a purpose. The already pregnant Redback females always kill their lover and, in most cases, also eat them. This provides them with a small reproductive advantage.Allowing spiders to take up places around houses can be beneficial in that they catch other annoying insects such as mosquitoes and flies.Rest assured that while you might see some large spiders, and perhaps even some poisonous ones, a good rule is to look and admire but don't touch any spider you find. Even those without poison could still have a nasty bite.1.Different families of spiders are identified themselves by ______.A.their physical characterB.their ways of getting foodC.the strength of their toxicityD.their effect on the environment2.What are the latest spiders in their evolution process?A.Spiders that chase down insects for food.B.Spiders that wait for the insects to come along.C.Spiders that can weave webs to catch flying insects.D.Spiders that actively go out to look for insects as food.3.If a spider stays on the wall of your house, you’d better ______.A.kill itB.feed itC.let it beD.chase it out4.What is the passage mainly talking about?A.A brief introduction of spiders.B.The evolution process of spiders.C.Living harmoniously with spiders.D.The living and feeing habits of spiders.2、Many people believe that you lose the ability to learn new languages as you get older. Language experts,however,will tell you that you’re never too old to learn a new language. As you get older, it can be more difficult to learn a new language,though.Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year. Because they need to learn language to became part of their communities.Adults,on the other hand,are already part of a language community. Learning a new language means becoming part of another language community,and adults rarely get the chance to practice as much as young children do.Moreover.children leaning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident Adults,however,often feel pressured to be perfect when learning a new language.This can discourage many people and make it even harder to learn a new language.When young children learn a new language,they come to see various languages as a “normal” part of society.This mindset(思维模式) helps them embrace learning a new language without feeling like they're doing something unusual or“too hard”.So if you want to learn a new language,go f or it! It’s never too late to learn a new language. If you're older,it may take more work,but it can be done.If you're a young child,though,now is the time to step out and learn a new language!1.By “Language is their life”,the author means that children .A.can't live without languageB.lead a happy life every dayC.practice a new language a lotD.are taken good care of adults2.What may make it hard for the old people to learn a new language!A.They are afraid of being laughed at.B.They usually have too many interests.C.They think making mistakes is natural.D.They always make all kinds of mistakes.3.Which of the following shows the difference between children and adults in learning new language?A.The behaviors they have.B.The learning attitudes.C.The future plans they have made.D.The materials they are using.4.According to the author,a new language .A.can never be learned by the old peopleB.can be grasped by the people easilyC.can be understood only by the old peopleD.can learned by both the old and the young3、Kids and teens are often dismissive of praise from their parents. I am sure that parents out there can relate to this, as we all have been told at one time or another by one or several of our kids,“Stop it, Mom.’’ or even,“You’re just saying that because you are my parents and you have to say that. " I can assure you, though, that they are listening. They will probably not thank you for this praise until they are in their twenties, but don't let that stop you from praising them duringtheir childhood and teen years. Just be careful how you praise them. A little praise may go a long way —especially if it is the right kind of praise.It appears that the way to go is to praise their efforts according to a study by Brummelman, of Utrecht University in the Netherlands and colleagues. These researchers concluded that kids should be praised primarily for their efforts, rather than for their personal characteristics, because if they are praised for effort, then a poor performance is more likely to be seen as a glitch(小故障), rather than a valid reflection of who they are as individuals.Let’s think about this together. If you are a teenager or a child of any age and are constantly told how brilliant you are, then when you do poorly on a test or a few tests, you may feel like you have suddenly lost your status as brilliant and may now feel ashamed that you are merely average or even dumb. If you are a girl who is constantly being told how beautiful you are, then on a day when you don’t look or feel so good, you may decide that you are unattractive. This is the problem that develops when we are praising our kids for global personality characteristics that they can't always live up to.1.According to the passage, which of the following statements is the right kind of praise?A.You are a great artist.B.You are very intelligent.C.Wow, you have a special gift for music.D.Your painting has indeed improved due to your efforts.2.Which of the following statements is TRUE according to the passage?A.All the children should be praised.B.There’s no need to praise kids and teens.C.Praise should be beyond children’s expectations.D.Teens often pay no attention to their parents’ praise.3.The underlined word “dumb” in the last par agraph can be replaced by _________.A.stupidB.uniqueC.curiousD.honest4.The main topic of this passage is _____.A.why to praise kids and teensB.how to praise kids and teensC.different ways to praise kids and teensD.the importance of praising kids4、Scientists, psychologists and English academics at Liverpool University have found that reading the works of the classical writers like Shakespeare and Wordsworth has a great effect on the mind, catches the reader’s attention and triggers moments of self-examination.Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others.In the first part of the research, the brain activity of 30 volunteers was monitored as they read passages from Shakespeare’s plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language.While reading the common texts, normal levels of electrical activity were shown in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than the common ones.Scientists went on to study the brain activity as it responded to each word and recorded how it lit up as the readers came across unusual words, surprising phrases or difficult sentences in the classical works. As a result, this lightening up process of the mind lasted longer than that when volunteers read common texts, encouraging further reading.The research also found that reading poetry especially increases activity in the right hemisphere(半球) of the brain, an area connected with “autobiographical memory”, driving the readers to think carefully about their own experiences based on what they have read. The academics said this meant the classical works of literature are more useful than self-help books.Philip Davis, an English professor who has worked on the study in the university’s magnetic resonance center, announced this week: “Classical literature acts like a rocket-booster to the brain, which provides extra power for the brain. You may never imagine how powerful it is. Theresearch shows such kind of literature can create new thoughts and connections in the young and the old.”1.The underlined word “trigger” in Paragraph 1 is closest in meaning to “______”.A.depends onB.picks upC.sets offD.changes into2.Which of the following is NOT true about reading classical literature?A.It makes readers’ brain more active than reading common texts.B.It makes readers’ electrical activity of brain return to normal.C.It’s help ful for readers to come up with new ideas.D.It’s an activity that is suitable for people of all ages.3.From the research, we can learn that ______.A.the readers prefer Shakespeare’s works to the other writers’ worksB.the words of classical works make it hard for volunteers to read furtherC.reading classical works produces a good and long-lasting effect on the mindD.poetry increases left-brain activity more than other literary forms4.What does the author mainly tell us in this passage?A.Shakespeare’s plays deserve to be read.mon books are unpopular anymore.C.Poetry is best for developing people’s brain.D.Classical works help the brain develop better.5、Do parents have a constitutional right to homeschool their children? No, according to a California District Court judge, who recently ruled that a child must be schooled "by a person holding a valid state teaching credential (文凭)for the grade being ta ught”.What started as a Los Angeles County child welfare case involving one specific family has gone into proceedings (诉讼) that have actually put on trial the very nature of what constitutes a sound education. “For decades we’ve been happily homeschoo ling, and then this comes up suddenly,” says Mary Griffith, a homeschooling parent. Griffith says California had traditionallygiven homeschooling parents the freedom to choose the kind of education they want for their child.This particular family in Los Angeles had enrolled their children in a private school independent study program not in their home. In response to abuse charges against the family, the children were enrolled in public schools. The parents stated they had a constitutional right to homeschool on religious grounds; that's when the court ruling was issued. However, Griffith says if the ruling ends up affecting anyone, it will mainly be those who also enroll their children inoff-site homeschooling. “This won't be far-reaching for homeschooling parents."That's how organizations like the Homeschool Association of California (HSC) would like to keep it, anyway, and they've hired a team of lawyers to limit the impact of the case. Griffith says the legal team for HSC is trying to establish that while this ruling may indeed be necessary for this particular family, it should not set a precedent(先例) for all.What does this case really mean for homeschooling families nationwide? According to Darren A. Jones, this decision is certain to affect homeschooling on a national scale. Jones claims that it is common for state courts to look to other states’ rulings for assistance in deciding issues where no precedent exists. “A poor legal decision in California could become part of a trend across th e nation.’’1.In Griffith’s opinion, ________.A.parents don’t have a right to homeschool their childrenB.a child must be schooled by an expert with a credentialC.homeschooling should be forbidden in the whole countryD.it is understandable for parents to homeschool their children2.The underlined word “this” in Para. 2 refers to the fact that ________.A.parents happily homeschool their childrenB.parents don’t have a right to homeschool their childrenC.a child must be schooled by a person with a teaching credentialD.a Los Angeles County child welfare case involves a special family3.Why were the particular family’s children enrolled in public schools?A.To avoid the abuse charges against them.B.To receive the better education in it.C.To break away from their parents.D.To cooperate with the expert’s jobs.4.What’s the author’s attitude towards whether parents have a right to homeschool their children?A.Supportive.B.Sympatric.C.Negative.D.Objective.6、Summer shouldn't mean taking a break from learning, especially reading. Studies show that most students experience a loss of reading skills over the summer months, but children who continue to read actually gain skills. So efforts should be made during the summer to help children keep reading skills, practice reading and read for enjoyment.Parents should remember that children need free time in the summer to relax and enjoy the pleasures of childhood. So summer reading should be fun. Following are a few tips to make reading enjoyable for your children this summer:Read aloud together with your child every day.Make it fun by reading outdoors on the front steps, patio, at the beach or park. Also, let your children read to you.Set a good example!Keep lots of reading material around the house. Turn off the TV and have each person read his or her book, including Mom and Dad.Read the same book your child is reading and discuss it.This is the way to develop habits of the mind and build capacity(能力) for thought and insight.Let kids choose what they want to read, and don’t turn your nose up at popular fiction. It will only discourage the reading habit.Subscribe, in your child’s name, to magazines.Encourage older children to read the newspaper and current events magazines, to keep up the reading habit over the summer and develop vocabulary. Ask them what they think about what they’ve read, and listen to what they say.1.Parents must help children read during the summer because ________.A.the summer holiday is too long a time for themB.reading is a kind of relaxation for childrenC.some of the reading skills may be lost if they stop readingD.children can enjoy the pleasure of childhood2.What does the underlined phrase "turn your nose up at” probably mean?A.Get interested in.B.Show one’s dislike for.C.Think highly of.D.Lose interest in.3.In oder to build children's capacity for thought and insight, parents should ______.A.subscribe to magazines in the child’s nameB.read the same book the child is reading and discuss itC.let children choose what they want to readD.turn off the TV4.What does the passage mainly tell about?A.Some summer reading tips for parents.B.Some useful advice on reading for children.C.What kinds of books to read in summer.D.How to teach children to read.7、Have you got the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware of. In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.Now scientists say there exist seven basic learning styles.·Linguistic: These people learn through listening, reading, speaking and writing.·Logical: These people learn with formula (公式) and principles (原理).·Visual: These people learn by seeing what they are studying.·Musical: These people learn well when information is presented through music.·Kinesthetic: These people learn from movement and physical activities.·Intrapersonal: These people learn best by linking new information directly with their own experiences.·Interpersonal: These people learn well by working with others.Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.1.From the passage, we know that our brains ______.A.deal with the information in different waysB.send out the information in the same wayanize information with our bodiesD.gather information in the same way2.A visual learner usually learns _____.A.through listening and speakingB.by seeing what he is learningC.from movement and physical activitiesD.by linking new information with his experience3.A musical learner will find it easy to learn ______.A.with formulas and principlesB.by working with othersC.through reading and writingD.through music he hears4.The purpose of the passage is to tell us to ______.A.learn more successfullyB.gather more informationC.understand more quicklyD.exchange information better8、In 2015 a paper published in a science magazine reported on the personality types of people living in various London districts. Extroverts (外向的人), the researchers who wrote it had discovered, favored Richmond. Those who were most open to experience gathered in Hackney. People in Barnet scored lower than average on emotional stability.What this study did not address was whether someone’s home range reflects their personality traits or imposes them. In other words, is what is going on “nature” or “nurture” (培育) ? However, in a piece of research just published, Dr. Holtmann of Otago University, in New Zealand, and his colleagues have filled that gap—at least, they have filled it for dunnocks.The dunnock is a European bird. It has, though, been introduced to New Zealand and its population has boomed there. It is a well-studied species, and, in particular, some being measurably bolder (更大胆的) and more tolerant of potential threats, such as nearby human beings, than others. The team’s research area was the Botanic Garden in Dunedin. This is open to the public, but some areas are more frequented by visitors than others. Dunnocks have small territories, so it was possible to measure the amount of human disturbance in a given territory with reasonable precision. And, by wrapping each of the dunnocks in the garden with colour-coded bands it was possible to identify individuals by sight. Altogether, the researchers looked at 99 of them.The y worked out a bird’s level of threat tolerance by the simple method of walking towards it, and then measuring how close one could get before the bird flew away. They did this several times for each bird every breeding season, and repeated the process over the course of three seasons.A particular bird’s flight distance (ie, how closely it could be approached before it departed) was, they found, consistent within a breeding season. From season to season most birds got a little bolder—probably as they learnt more about the world and what they could safely get away with. But this increase in boldness with age was small compared with the different starting points of bold and shy birds when they first arrived in a territory. It did not, therefore, much affect the factthat, on average, birds’ flight distances were inversely correlated (负相关) with the level of human disturbance in their territories. This was a consequence of disturbed territories being settled by bold birds, and undisturbed territories by shy ones.In the case of dunnocks, then, nature wins over nurture. Dr. Holtmann was able to show that personalities match circumstances, rather than being created by them. Dunnocks can recognize which places suit them best, and choose to settle in them shortly after they are fully fledged (羽翼丰满). Most likely, that is happening in London districts, too.1.What does the underlined words “that gap” in the second paragraph refer to?A.What the paper published in 2015 failed to handle.B.Why extroverts favour certain areas in London district.C.How Dr. Holtmann involved dunnocks in his study.D.What the former and latter study have in common.2.From Paragraph 3, we can know that dunnocks ________.A.are native to New ZealandB.have distinct personalitiesC.are bolder than human beingsD.can be easily identified by its color3.What conclusion did Dr. Holtmann draw from his study?A.It’s nurture rather than nature that matters in the case of dunnocks’ behaviour.B.Birds’ flight distances were in proportion to huma n disturbance in their territories.C.Dunnocks choose their habitats wisely in the first place rather than adapt to them.D.Bold birds and shy birds alike settle in undisturbed territories in the botanic garden.4.What is the author’s purpose in writing th e passage?A.To argue that circumstances cultivate certain personalities.B.To entertain readers with some funny facts about dunnocks.C.To present the finding of a scientific research about dunnocks.D.To confirm the assumption that personalities match circumstances.答案以及解析1答案及解析：答案：1.B; 2.C; 3.C; 4.A解析：1.细节理解题。
