高中英语阅读理解科技类
高中英语阅读理解科技类一Excused from recycling(回收利用) because you live in a high rise with a rubbish chute(垃圾道)? You won't be for long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .In Shantzis' Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other floors' chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables Sorting(分类) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective.1．The purpose in writing this text is _________.A．to encourage people to recycle their rubbishB．to introduce a recycling system for high risesC．to describe the use of computer technology in recyclingD．to explain the need for rubbish collection in high rises2．When he says "You won't be for long" the writer means that _______.A．you'll soon be living in a cleaner buildingB．rubbish chutes will become out of date before longC．you won't wait long for your turn to recycle rubbishD．it won't be long before you'll have to recycle your rubbish3．Before dropping rubbish into the chute you have to ___________A．lock the other floors' chute doors B．check if the container is fullC．press the correct button D．break up the rubbish4.．The biggest advantage of this new system is that _________A．it reduces the cost of recycling B．it saves time and spaceC．it saves money for people living in high risesD．it makes better use of the existing recovery equipmentBAccording to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.The project, called Hywind, is the world’s first large-scale deepwater wind turbine(涡轮发电机). Although it uses a fairly standard 152-ton, 2.3-megawattturbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(缆索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind’s stability(稳定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the wh ole spar’s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture )Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.1. The Hywind project uses totally new technology to ensure the stability of _______.A. the cables which tie the spar to the ocean floorB. the spar which is floating in deep-sea waterC. the blades driven by strong and steady sea windD. the stones filled in the spar below the sea surface2. To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designed with its gearbox sitting ____________.A. on the sea floorB. on the spar topC. at sea levelD. behind the blades3. Wide applications of deepwater wind power technology can ____________.A. solve the technical problems of deepwater windmillsB. make financial profits by producing more turbinesC. settle the arguments about environmental problemsD. explore low-carbon power resources available at seaB DC A BCD。

高考英语阅读理解复习-科技类20篇(含解析)
科技类词汇对应阅读passage1A snake﹣robot designer，a technologist，an extradimensional physicist and a journalist walk into a room.The journalist turns to the crowd and asks：Should we build houses on the ocean？Like a think﹣tank panel，members of the team dream up far﹣out answers to the crucial problem，such as self﹣driving housing units that could park on top of one another in the coastal city center.The setting is X，the enterprise which considers more than100ideas each year，in areas ranging from clean energy to artificial intelligence.Although only a tiny percentage become"projects"with far﹣reaching creativity，these projects exist，ultimately，to change the world，like Waymo，the biggest self﹣driving﹣car company.In the past60years，something strange has happened.As the academic study of creativity has thrived （蓬勃发展），the label innovation may have covered every tiny change of a soda can or a toothpaste flavor，but the rate of productivity growth has been mostly declining since the1970s.John Fernald，an economist，points out that the notable exception to the post﹣1970decline in productivity occurred when businesses throughout the economy finally figured out the breakthrough technology﹣information technology.John Fernald says，"It's possible that productivity took off，because we picked all the low﹣hanging fruit from the IT wave."Actually，the world economy continues to harvest the benefits of IT.But where will the next technology shock come from？Breakthrough technology results from two distinct activities﹣invention and innovation.Invention is typically the work of scientists and researchers in labs，while innovation is an invention put to commercial use.Seldom do the two activities occur successfully under the same roof.They tend to thrive in opposite conditions；while competition and consumer choice encourage innovation，invention has historically progressed in labs that are protected from the pressure to generate profit.Allowing well﹣funded and diverse teams to try to solve big problems is what gave us the computer and the Internet.Today，we fail to give attention to planting the seeds of this kind of ambitious research，while complaining about the harvest."Companies are really good at combining existing breakthroughs in ways that consumers like.But the breakthroughs come from patient and curious scientists，not the rush to market，"says Jon Gertner，the author of The Idea Factory."Technology is a tall tree，"John Fernald said."But planting the seeds of invention and harvesting the fruit of innovation are entirely distinct skills，often mastered by different organizations and separated by manyyears."As for me，both of them are essential for technology，although they are relatively independent.I don't think X is a planter or a harvester，actually.It is like building taller ladders.Nobody knows for sure what，if anything，the employees at such enterprises are going to find up on those ladders.But they're reaching.At least someone is.（1）What is the main purpose of the first two paragraphs？A．To present the process of group discussion.B．To illustrate X's worry about big problems.C．To reveal the importance of the crazy ideas.D．To stress the varied backgrounds of the team.（2）What can we learn from the passage？A．Breakthroughs must stand the test of the market.B．Innovation on necessities can promote productivity.C．Invention develops slowly under the pressure of profit.D．The harvest of innovation lies in some ambitious research.（3）Regarding John Fernald's view on technology，the author is.A．supportiveB．cautiousC．uncertainD．critical（4）What can be inferred about X from the passage？A．It will focus on innovation.B．It will have its outcome soon.C．It may give in to its fruitless reality.D．It may bring an encouraging outlook.【分析】这是一篇说明文。

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

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 heat…当它恢复直立时底部吸热……the head then rejects some energy as heat头部放热and the bird drinks again.然后饮水鸟再次喝水These two flows define a heat engine:这种热传递定义了热机：a device, operating in a cycle一种循环运行的装置that absorbs heat from a high temperature reservoir,从高温热源处吸热converts part of it into work,将部分热能转化为功and rejects the remainder into a low temperature reservoir.向低温热源放热The fact that this is a heat engine饮水鸟就是热机这一事实means it’s related to the great machines that make our globalized world happen:表明它跟实现全球化的许多伟大机器有关among those the mighty steam turbine that generates electricity,其中有能发电的大型蒸汽轮机the giant diesel engine that propels container ships across the oceans,推动货轮穿越海洋的大型柴油机and the great gas turbine that flies us around the globe.还有让我们飞遍全球的燃气轮机（三）人们是否应该接受人造肉Lab-Grown Meat Is Coming to Your

高中英语-阅读理解(科技类)01
阅读理解〔科技类〕Passage OneThe computer is a useful machine. It is the most important invention in many years. The oldest kind of computer is the abacus(算盘), used in China centuries ago, but the first large, modern computer was built in 1946. A computer then could do maths problems quite fast.Today computers are used in many ways and can do many kinds of work. In a few years the computer may touch the life of everyone, even people in faraway villages.In the last few years, there have been great changes in computers. They are getting smaller and smaller, and computing faster and faster, Many scientists agree that computers can now do many things, but they cannot do everything. Who knows what the computers of tomorrow will be like? Will computers bring good things or bad things to people? The scientists of today will have to decide how to use the computers of tomorrow.1. The computer is a _______ machine.A. helpfulB. strangeC. largeD. dangerous2. The first large, modern computer was built about _______ years ago.A. a fewB. fortyC. sixtyD. eighty3. The computers of today are _______ than before.A. biggerB. fewerC. smallerD. taller4. Computers can do _______.A. everythingB. anythingC. nothingD. lots of things5. The scientists of today _______ how to use the computers of tomorrow.A. may decideB. must decideC. can makeD. needn’t makePassage TwoWarm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.1. Hundreds of years ago, Sir Francis Bacon found _______.A. the temperature of warm water drops faster than that of cold waterB. warm water is heavier than cold waterC. warm water has the same temperature as cold waterD. warm water is not as useful as cold water2. What Sir Francis Bacon said was right, but people didn't believe him until _______.A. late in the 20th centuryB. early in the 20th centuryC. three years agoD. late in the 19th century3. Leave a pail with warm water and another pail with cold water in the same low temperature, you’ll find that _______.A. cold water freezes firstB. warm water turns into ice before cold waterC. warm water and cold water freeze at the same timeD. much of cold water is changed into air.4. Why does warm water freeze first in the same freezing weather?A. Because some of the warm water turns to vapor, the amount(数量) becomes less than that of cold water.B. Because warm water is lighter than cold water.C. Because the temperature of warm water is lower than that of cold water.D. Because cold water freezes with more difficulty than warm water.Passage ThreeIf you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.1. The main reason for one is poor memory is that _______.A. his father or mother may have a poor memoryB. He does not use his name or legs for some timeC. his memory is not often usedD. he can’t read or write2. If you do not use your arms or legs for some time _______.A. you can’t use them any moreB. they will become strongerC. they become weak and won’t become strong until you use them again.D. they will become neither stronger nor weaker3. Which of the following is NOT true?A. Your memory works in the same way as your arms or legs.B. Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.C. Don’t learn how to read and write if you want to h ave a better memory.D. A good memory comes from more practice.4. Some people can’t read or write, but they usually have better memories, because _______.A. they have save much troubleB. they have saved much time to remember thingsC. they have to use their memories all the timeD. they can’t write everything in a little notebook5. Which is the best title for this passage?A. Don’t Stop Using Your Arms Or LegsB. How To Have a Good MemoryC. Strong Arms And Good MemoriesD. Learn From the PeoplePassage FourWhen Johnson called again, the manager received him very politely. “That is a most remarkable oil you brought us, Mr Johnson,” he said. Johnson nodded his smooth, dark head. That was something he knew very well. “I’ve never seen anything like it,” the manager admitted. Johnson nodded again. “No?” he said politely. Then he added, “But I think you will, sir. A very great deal of it.” He appeared to think for a moment. “I think you will find it will be on sale seven, perhaps, eight years from now.” He smiled.The manager thought that was uncertain. He said, “It is better than our fish oils. I admit that.”“So I am told, sir,” agreed Johnson.“Have you any plans to produce it yourself, Mr Johnson?”“Would I be showing it to you if I had?” Johnson smiled again.“We might add some chemicals to one of our own fish oils,” said the manager. “It would be expensive to do that, even if you could,” Johnson said gently. “Besides,” he added, “I am told that this oil will be much cheaper th an your best fish oils. Cheaper than any vegetable oil, in fact.”“Perhaps,” said the manage. “Well, I suppose you want to make an arrangement, Mr Johnson. Shall we discuss it?”“Of course,” said Johnson. “There are two ways of dealing with a situation o f this sort. The usual one is to prevent it altogether or at least to delay it as long as possible. That is, of course, the best way.” The manager nodded. He knew plenty about all that.“But I am so sorry for you, because, you see, that is not possible this time.” The manager had his doubts, but all he said was an inquiring(asking), “Oh?”“The other way,” continued Johnson, “is to produce yourself before the trouble starts.”1. The manager thought of adding chemicals to the fish oil to make it _______.A. cheaper than the new oilB. more quicklyC. more expensiveD. as good as the new oil2. Johnson’s new oil would be _______.A. more expensive than fish oil, but betterB. less expensive, and betterC. less expensive, but not goodD. more expensive, and not so good3. Johnson expressed his regret that the manager _______.A. could not stop the new oil being madeB. would never know how to make itC. had spent a lot of money on itD. d idn’t know enough about it4. Johnson showed his new oil to the manager because he wanted _______.A. to produce it himselfB. to prevent it being producedC. to be paid not to produce itD. the manager to produce itPassage FiveCan you remember the first time you learned to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills, you will never go back to the old days. The new technology is simply too convenient and too powerful.Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy(侵犯隐私), fraud(欺诈), and computer-related mistakes are just a few shocking examples.The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.1. The writer thinks learning about computers is like learning how to ride a bike or drive a car because _______.A. it is simple and practicalB. it needs a lot of practiceC. it leads people to new life experiencesD. it takes much time to master the skills2. According to the passage, computers bring people the following benefits except _______.A. avoiding mistakesB. saving moneyC. making moneyD. opening up opportunities3. According to the writer, the bad effects of computers can be avoided if we _______.A. have sound knowledge of computer systemsB. tell people not to misuse computersC. have strict rules over the use of computersD. make more investments in the technology4. This passage is probably written for _______.A. computersB. computer producersC. computer learnersD. computer programmersPassage SixPerhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots of things you can do. You can send E-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW).There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at only time.Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?1. What is the passage mainly about?A. Internet.B. Information.C. Computers.D. E-mails.2. Which is the quickest and cheapest way to send messages to your friends?A. By post.B. By E-mail.C. By telephone.D. By satellite.3. Which may be the most possible place for people to work in tomorrow?A. In the office.B. At school.C. At home.D. In the company.4. Whose the owner of the Internet?A. The headmaster.B. The officer.C. The user.D. No one.5. What does the writer try to tell us with the last two sentences?A. English is important in using the Internet.B. the Internet is more and more popular.C. Most of the information is in English.D. Every computer must have the Internet.Passage SevenIn most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.Many teenagers like electronic games so much that they can’t stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”. They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the wrist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call “Space Warrior’s Wrist”.Other strange aches and pains also are likely to affect the elbows and shoulders.Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(晕倒) and fell to the floor.Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.1. Electronic games are found very popular with _______.A. people living in townsB. students studying in high schoolsC. girls wo rking in their father’s workshopsD. young people2. “Space Warrior’s Wrist” is caused by _______.A. constantly pressing the buttonsB. rapidly moving across the screenC. tightly holding the joystick controlsD. inflamed and swollen muscles of the wrist3. The case of a 17-year-old girl given by the writer shows that the writer _______.A. supports playing electronic gamesB. feels very sorry for the girlC. disagreed with young people’s playing electronic gamesD. feels worried about young people’s poor health4. From the passage we can conclude that playing electronic games is _______.A. enjoyable and helpful to the studyB. exciting but harmful to the health and studyC. interesting but harmless to the eyesD. amusing and satisfyingPassage EightExperiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago.West German astronaut Ulf Merbold disproved the theory during tests aboard the spaceship yesterday. His discovery is connected with the workings of the inner ear, the body’s balance mechanism(机制).In l914 Professor Robert Barany won the Nobel prize for Physiology(生理学) and Medicine when he announced that temperature differences affected the inner ear and caused the eyes to blink(眨眼). Histheory was accepted by scientists.But Merbold carried out tests to find if the theory was correct and shocked himself and space officials when he proved it wrong.According to Barany’s theory the eyes would blink when cold air was blown into one ear and hot air blown into the other.But if this theory was correct such a movement would be impossible in zero gravity.Both Merbold’s eyes cont inually blinked when the test was carried out.1. Tests were carried out in outer space in order to _______.A. find what causes the eyes to blinkB. shock the worldC. prove the theoryD. disprove the theory2. Barany’s th eory declared to prove _______.A. how our hearing mechanism worksB. why we constantly move our eyesC. that eye movement is affected by temperatureD. how hearing reacts(反应)3. Barany’s theory was proved incorrect in space by the effects of _______.A. having no weightB. having no airC. the pull of gravityD. hot and cold air streamsPassage NineScientists are developing a new kind of machine to take the place of humans. These machines can do jobs in places that are too dangerous for humans. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space.John Marrit, a psychologist(心理学家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s m ovements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.1. The new kind of machine being introduced in the passage is _______.A. in existenceB. only an ideaC. being tried outD. being researched and developed2. The machine _______.A. follows the perso n’s orderB. is controlled by a computerC. does exactly what the person doesD. is controlled by a television on the person’s head3. The difference between such a new machine and a robot is that _______.A. the new machine is more difficult to make than a robotB. the new machine is more difficult to be controlledC. a robot is controlled by man indirectlyD. a robot can’t be used in places too dangerous or farawayPassage Ten. HoneybeesHoneybees can do three kinds of jobs.The honeybee is one of the most unusual insects in the world. Bees are special because they divide up their work. Each bee has a certain job to do.The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixingthe hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.1. The bee’s nest is called a _______.A. droneB. honeycombC. hiveD. wax2. Wax is used to make the _______.A. nestB. honeycombC. fanD. hive3. Which jobs do workers do?A. They lay 2, 000 eggs each day and build a nest.B. They mate with the queen bee and then starve.C. They clean the hive and keep it cool.D. They attack the queen bee.4. According to the story, bees _______.A. are very dangerous insectsB. will attack anything or anyone to protect the hive, if necessaryC. are like any other insect that fliesD. eat each other as food5. The drone is driven away when its job is finished, because _______.A. it attacked the workersB. it is no longer needed in the hiveC. the queen bee has diedD. it ate the queen beePassage ElevenAmerican doctors say that mothers who smoke cigarettes before their babies are born may slow the growth of their babies’ lungs. They say reduced lung growth could cause the babies to suffer breathing problems and lung disease later in life. Doctors in Boston, Massachusetts studied 1 100 children. The mothers of some of the children smoked, the other mothers did not. Doctors found that the lungs of the children whose mothers smoked were 8% less developed than the lungs of the children whose mothers did not smoke, and that the children whose mothers smoked developed 20% more cold and breathing diseases than other children later in life.Another recent study found that children had a greater chance of developing lung cancer if their mothers smoked. The study also showed that the danger of lung cancer increased only for sons and not for daughters, and that the father’s smoking did not affect a child’s chance of developing lung cancer.1. Mother who smokes before her child is born may _______.A. slow the growth of her baby’s lungB. cause her baby to suffer breathing problems and lung disease later in lifeC. make her child develop lung cancerD. All of above are right2. Doctors in Boston studied 1 100 children to _______.A. examine whether these children were healthyB. find out whether their mothers had smokedC. find why these children suffered breathing problems and lung diseaseD. look into the effect that mother’s smoking had on their children3. Suppose John’s father was a heavy smoker, so was Mary’s mother. According this passage, _______.A. John is more likely to develop lung cancerB. Mary is more likely to develop lung cancerC. John and Mary have the same chance to develop cancerD. neither John nor Mary has the chance to develop cancer4. This passage is to _______.A. warn us of the danger of smoking before childrenB. warn people with breathing problems not to smokeC. warn us that mothers who smoke may affect their children’s healthD. warn us that fathers who smoke may affect their children as mothersPassage TwelveYou can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.1. You can see the book because_______.A. your eyes are close to itB. it reflects some of the sunlightC. it has light of its ownD. your eyesight can get to it2. The underlined word “luminous” means_______.A. visibleB. all colorsC. giving off lightD. sunlight3. ________ have light of their own.A. The sun and the moonB. The stars and the earthC. The sun and the starsD. The moon and the earth4. Which of the following is true?A. All the things you can see give off light.B. Light from the book is much shorter than that from the moon.C. The moment you open your eyes the light from the book travels to your eyes.D. Light travels so fast that there is no time for you to read.Passage ThirteenAs people continue to grow and age, our body systems(系统) continue to change. At a certain point in your life your body systems will begin to weaken. Your strength may become weaker. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this change that leads us toward the end of our lives.Many factors(因素) decide your health. A good diet plays an important role. the amount and type of exercise you get is another factor. Your living condition is yet another. But scientists studying agingproblem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.There is nothing to be afraid of as old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often you get better understanding of yourself and the world.What we consider old age now may only be middle-aged some day soon. Who knows, with so many advances in medical science happening so quickly, life length may one day be measured in centuries, rather that in years!1. When people become aging, they will lose some of their ability to bounce back from disease and injury, “bounce back” here means _______.A. to escape from disease and injuryB. to improve one’s health after one’s disease and injuryC. to jump backwardD. to run fast2. Many consider the later part of life to be the best time of living because ______.A. they consider their life has been a successful oneB. they have come through the battle of life safelyC. they have less misunderstanding of themselves and the outside worldD. they have nothing to do all day long only to watch their grandchildren growing up around them高一英语阅读理解试题〔科技类〕答案：A【答案与解析】本文讲电脑的发展历史。

高中英语阅读理解科技类-一高中英语阅读理解科技类一Excused from recycling(回收利用) because you live in a high rise with a rubbish chute(垃圾道)? You won't be for long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .In Shantzis' Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other floors' chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables Sorting(分类) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzis believeshis system could help recycled materials become more cost-effective.1．The purpose in writing this text is _________.A．to encourage people to recycle their rubbishB．to introduce a recycling system for high risesC．to describe the use of computer technology in recycling D．to explain the need for rubbish collection in high rises2．When he says "You won't be for long" the writer means that _______.A．you'll soon be living in a cleaner buildingB．rubbish chutes will become out of date before longC．you won't wait long for your turn to recycle rubbishD．it won't be long before you'll have to recycle your rubbish 3．Before dropping rubbish into the chute you have to ___________A．lock the other floors' chute doors B．check if the container is fullC．press the correct button D．break up the rubbish4.．The biggest advantage of this new system is that _________A．it reduces the cost of recycling B．it saves time and space C．it saves money for people living in high risesD．it makes better use of the existing recovery equipment BAccording to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.-scale deepwater wind turbine(涡轮发The project, called Hywind, is the world’s first large电机). Although it uses a fairly standard 152-ton, 2.3-megawattturbine, Hywind represents totally newtechnology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),athe Norwegian company StatoilHydro, has developed recently. The technology Hy wind’s creator,steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to theocean floor by three cable(缆索)；these will keep the spar stable and prevent the turbine frommoving up and down in the waves. Hywind’s stabi lity(稳定性)in the cold and rough sea wouldprove that even the deepest corners of the ocean are suitable for wind power. If all goes accordingto plan, the turbine will start producing electricity six miles off the coast of southwestern Norwayas early as September.To produce electricity on a large scale, a commercial wind farm will have to use biggerturbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the wh ole spar’s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture )Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helpsovercome the windmill-as-eyesore objection. If the technology catches on, it will open up vast-carbon power sources available.areas of the planet’s surface to one of the best low1. The Hywind project uses totally new technology to ensure the stability of _______.A. the cables which tie the spar to the ocean floorB. the spar which is floating in deep-sea waterC. the blades driven by strong and steady sea windD. the stones filled in the spar below the sea surface2. To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designedwith its gearbox sitting ____________.A. on the sea floorB. on the spar topC. at sea levelD. behind the blades3. Wide applications of deepwater wind power technology can ____________.A. solve the technical problems of deepwater windmillsB. make financial profits by producing more turbinesC. settle the arguments about environmental problemsD. explore low-carbon power resources available at seaB DC A BCD。
