科技英语阅读答案【篇一:科技英语阅读答案unit 4】(robots)part i est readingreading 1section a pre-reading taskwarm-up questions: work in pairs and discuss the following questions.1. how does a qb work?qb has a speaker, microphone, camera, and video screen. it connects to the internet over wi-fi. you control it from your computer in a web browser, using a headset and screen. if you have a camera you can show live video of yourself, or you can show a still picture on bad hair days.2. is driving a qb difficult? is there a hand-held control device i can use with my computer to control the anybot?its pretty easy. you use the 4 arrow keys to make it turn, go forward or back. its built-in guidance system takes care of the rest by avoiding furniture and people, and gliding straight through doorways. all the time you’re seeing real-time video from the robot’s head, so you know where you are. most people get used to it in a few minutes.not necessary, all you need is your keyboard.3. is a wi-fi network in the home or business needed?yes. you should have 802.11g access points for best results. you should use encryption – wpa2 is easiest. we find meraki business-class access points work well and are affordable and easy to set up. they have long-range and outdoor models too.4. what kind of sensors does the anybot have, and what is the resolution on the anybot camera?two cameras, 3 microphones, lidar, a 3-axis gyroscope and encoders on the wheels. the main camera is 5 megapixels.5. how do you control or drive the anybot?you should control or drive it through a web browser. you dont need any special equipment, but you’ll sound better with a headset.section c post-reading taskreading comprehension1. directions: work on your own and fill in the blanks with the main idea.part 1 (paras. 1-5): brief introduction to the qbpara. 1: the appearance and advantages of the qb.para. 2: the fields in which the qb will be applied.para. 3: the composition of the qb.para. 4: useful designing makes the

qbpara. 6: the objective and planned procedure of the test drive. para. 7: the actual performance of the qb in completing the planned mission.para. 8: the built-in lidar system and the camera enable the qb move smoothly.para. 9: the qb’s laser-pointer eye turned out to be useful when greeting people.para. 10: a valuable lesson has been learned through the test drive: never drive outside therange of the wi-fi network.para. 11: the qb slips down along the ramp when the wi-fi connection drops.2. directions: work in pairs and discuss the following questions.1) what can a robot do in your daily life?they can move materials, parts, tools, or other specialized devices to perform a variety of tasks. nowadays, they are also capable of attending meetings for you.2) what does a robot look like?undoubtedly, different robots look differently. the qb just looks like a floor lamp mounted on a vacuum cleaner.3) can a robot be remotely controlled? how?yes, through a web browser.4) have you ever heard of the qb?5) have you seen any movies related to robots, do you believe that these robots will be created and applied in the real life?6) suppose that you were a businessman, how will you use it to bring customers in?7) do you desire to have a qb of your own?3. directions: read the following passage carefully and fill in the blanks with the wordsyou’ve learned in the text.qb —anybots, inc.’s newly surrogate robot will be available to the public soon. despite its $15,000 price and its not-so-handsome appearance: it looks like a floor lamp on a cleaner, the company believes that its high-tech will appeal to a new generation of workers who’d like to be in contact without sacrificing ―presence‖. the qb has a speaker, microphone, camera, pointer, system and video screen. it connects to the browser, using a headset and screen. although the operator cannot be there if the operator has a camera he can show live video of himself, or he can show a still picture on bad hair days.vocabulary and structure1. directions: give the correct form of the word according to the indication in the brackets. then complete the sentences using the right form for each word. use each word once.1) avoidance, traditionally considered a high level planning problem, can beeffectively distributed between different levels of control, allowing real-time robot operations in a complex environment. 2) it covers the higher level techniques of perspective projection, analyticalphotogrammetry, motion, image matching, consistent labeling, model matching, and knowledge-based vision systems.3) on large feet for stability.4) anthropomorphic series-actuated robot-arms.5) aspects of the performance of in-parallel-actuated robot-arms are compared and contrasted with those of series-actuated arms.6) we have experimented with the planner using several computer-simulated robots,including rigid objects with 3 dofs (in 2d work space) and 6 dofs (in 3d work space)7) the execution of a task, as regards to both physical activity and decision making.8) in the course of centuries, human being have constantly attempted to seek substitutes thatwould be able to mimic their behavior in the various instances of with the surrounding environment.9) by its usual meaning, the term automation a technology aimed at replacinghuman being with machines in a manufacturing process, as regard not only the execution of physical operations but also the intelligent processing of information on the status of 10) by virtue of its programmability, the industrial robot is a typical component of rigid automated systems and in flexible automated systems.2. directions: complete the sentences with the words given in the brackets. change the form if necessary.1) this is significant because it is not obvious that the theory can be extended to include anaccount of quantifier scope without an appeal to additional representational levels. a full the work, but this reviewer would

areas as such.7) they suggest that having an expressive face and indicating attention with movement both make8) (control group) or via telemedicine (telemedicine group) and were followed prospectively.9) unlabeled data are available with littlecost, it is therefore natural to ask the question that in addition to human labeled data, whether one can also take advantage of the unlabeled data in order to improve the effectiveness of a ofa machine-learned categorizer.10) burst are dropped.3. directions: reorder the disordered parts of sentences to make a complete sentence.1) given that robots generally lack muscles, they cant rely on muscle memory (the trick thatallows our bodies to become familiar over time with movements such as walking orbreathing) to help them more easily complete repetitive tasks.2) for autonomous robots, this can be a bit of a problem, since they may have toaccommodate changing terrain in real time or risk getting stuck or losing their balance.3) one way around this is to create a robot that can process information from a variety ofsensors positioned near its ―legs‖ and identify different patterns as it moves, a team of researchers report sunday in nature physics.4) some scientists rely on small neural circuits called central pattern generators (cpg) tocreate walking robots that are aware of their surroundings.5) some researchers are leading

following questions.1. do you have any idea about the middle ages? and the dark ages in human history?【篇二:科技英语阅读答案unit 8】/p> unit 8 space explorationpart i est readingreading 1section a pre-reading taskwarm-up questions: work in pairs and discuss the following questions.1. how much do you know about the space?space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction.[1] physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of the boundless four-dimensional continuum known as spacetime. in mathematics one examines spaces with different numbers of dimensions and withdifferent underlying structures. the concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.2. how do you understand the title “does god play dice”?the science of chaos is forcing scientists to rethink einsteins fundamental assumptions regarding the way the universe behaves. chaos theory has already shown that simple systems, obeying precise laws, can nevertheless act in a randommanner. perhaps god plays dice within a cosmic game of complete law and order. does god play dice? reveals a strange universe in which nothing may be as it seems. familiar geometric shapes such as circles and ellipses give way to infinitely complex structures known as fractals, the fluttering of a butterflys wings can change the weather, and the gravitational attraction of a creature in a distant galaxy can change the fate of the solar system.3. what is determinism?determinism (specifically causal determinism) is the concept that events within a given paradigm are bound by causality in such a way that any state (of an object or event) is, to some large degree, determined by prior states.4. how do you understand “the world must have seemed pretty arbitrary and random”?disasters such as floods or diseases must have seemed to happen without warning, or apparent reason. primitive people attributed such natural phenomena, to a pantheon of gods and goddesses, who behaved in a capricious and whimsical way. there was no way to predict what they would do, and the only hope was to win favor by gifts or actions. many people still partially subscribe to this belief, and try to make a pact with fortune.5. do you think we can predict absolutely what is going to happen?of course not. some disasters like may 12 earthquake have proved that “no living man all things can.”section c post-reading taskreading comprehension1. directions: work on your own and fill in the blanks with the main idea.part 1 (para. 1): brief introduction to the topic.para. 1: brief introduction to the topic.part 2 (paras. 2-3): laplace’s idea of scientific determinism.para. 2: introduction to scientific determinismpara.3: the connotation of determinismpart 3 (paras. 4-5): planck’s quantum mechanicspara. 4: introduction to quantum mechanics.para. 5: the connotation of quantum mechanics.2. directions: work in pairs and discuss the following questions.1) do you think we can predict what will happen?sometimes yes, sometimes not. we can predict what will happen in principle.2) can you give list some regularities in the behavior of nature? (open)3) how do you understand “a scientific law is not a scientific law, if it only holds when somesupernatural being, decides to let things run, and not intervene”?in effect what he said was, that if at one time, we knew the positions and speeds of all the particlesin the universe, then we could calculate their behavior at any other time, in the past or future.4) how much do you know “quantum mechanics”?quantum mechanics is the study of the relationship between quanta and elementary particles.among other relationships the valence shell electrons and photons are quantized. quantummechanics is a fundamental branch of physics with wide applications in both experimental andtheoretical physics. quantum theory generalizes all classical theories, including mechanics,electromagnetism (except general relativity), and provides accurate descriptions for manypreviously unexplained phenomena such as black body radiation and stable electron orbits.theeffects of quantum mechanics are typically not observable on macroscopic scales, but becomeevident at the atomic and subatomic level.5) what has been a central tenet of science, ever since laplace’s time?the idea that the state of the universe at one time determines the state at all other times, has been acentral tenet of science, ever since laplace’s time.3. directions: read the following passage carefully and fill in the blanks with the words or phrases you’ve learned in th e text.newton’s theory of gravity to predict the motion of almostall expressed by laplace. in effect what he said was that if at one time, we knew the positions and speeds ofvocabulary and structure1. directions: give the correct form of the word according to the indication in the brackets. then complete the sentences using the right form for each word. use each word on.them.2. directions: complete the sentences with the words given in the brackets. change the form if necessary.1) most of the aud ience ueservedly subscribed to prof. tom’s proposal on space explorationin last lecture.在上次讲座里,多数听众毫无保留地赞同汤姆教授在空间探索方面的建议。

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。

科技英语阅读李健答案

科技英语阅读李健答案【篇一:科技英语阅读(李健版)翻译u3】物的适应性植物为了生存也必须像人类和动物一样适应周边的环境。

生存就意味着竞争,我们很难想象植物之间的竞争,但它往往又存在的。

首先,不同的植物之间会争夺阳光、空气、土壤和水。

其次,植物也会与那些吃它或者威胁到它生存环境的人类和动物竞争。

再次,植物所处的环境也可能也是有敌对性的或者不利于植物生长的。

怎样才能有足够的阳光、水分、空气和土壤?气温的冷热就是植物生长的主要因素吗?光对于植物来说是最基本的,尤其是对于绿色植物来说。

绿色植物在光下能制造养分——这是一种被称为光合作用的过程,而光也能影响水分蒸发的速率和花的形成。

温度也是必须考虑的因素。

对于大多数植物来说,所处的温度低于一度或者高于四十三度都将对其造成严重的损伤甚至死亡。

而温度也直接影响了种子的萌芽以及开花,当然温度也决定了它们的地理分布。

没有水植物也是无法生存的。

有些植物的生长过程需要大量的水分,因此潮湿的空气、大量的降水以及溪流湖泊和湿润的土壤对于植物都是重要的。

大多数植物需要有足够空气。

大气中所包含的一些必要的气体包括:氧气、二氧化碳、水蒸气和氮气。

空气移动所产生的风对于植物也有很大影响。

风有助于传播花粉、孢子和种子从而将它们播种在各种地方,但强风也有可能折断或者损害植物,尤其是大树。

而大风吹走了一些有养分的土壤,也会加快水分的蒸发甚至使植物缺水。

土壤对于陆生植物来说是必不可少的。

大部分植物生长在自然土壤里:其中包含着它的湿度、酸度、矿物成分、含氧量。

植物生长也会受到其他竞争生物的影响。

它必须能适应寄生菌、饥饿的鸟类、牛羊等食用叶子的动物,但植物也需要动物帮助传播花粉以及播洒种子。

有树叶和枝干的树以及灌木向我们展示了它们的适应性,这也告诉了我们植物是怎样获得最大量的光和空气的。

和那些山毛榉树、榆树、橡树、苹果树和栗子树一样,它们有一些芽最初是垂直生长的然而另一些却变成了水平生长。

为了能得到最多的阳光,一些垂直生长的枝芽会螺旋缠绕生长以至于不会遮挡到自己下边的叶子。

科技英语阅读答案Unit 6, 10

Unit 6 Mechanics and AutomotivesPart I EST ReadingReading 1Section A Pre-reading TaskWarm-up Questions: Work in pairs and discuss the following questions.1.What do you think will be the most popular mechanic field in the future? And why?(Open)2.Do you know anything about NANO-BIO technology?Nanobiotechnology is the branch of nanotechnology with biological and biochemical applications or uses. Nanobiotechnology often studies existing elements of nature in order to fabricate new devices. The term bionanotechnology is often used interchangeably with nanobiotechnology, though a distinction is sometimes drawn between the two. If the two are distinguished, nanobiotechnology usually refers to the use of nanotechnology to further the goals of biotechnology, while bionanotechnology might refer to any overlap between biology and nanotechnology, including the use of biomolecules as part of or as an inspiration for nanotechnological devices.3.Have you ever heard of CAD in engineering design?CAD: Computer-aided design (CAD), also known as computer-aided drafting and design (CADD), is the use of computer technology for the process of design and design-documentation. Computer Aided Drafting describes the process of drafting with a computer. CADD software, or environments, provide the user with input-tools for the purpose of streamlining design processes; drafting, documentation, and manufacturing processes. CADD output is often in the form of electronic files for print or machining operations. The development of CADD-based software is in direct correlation with the processes it seeks to economize; industry-based software (construction, manufacturing, etc.) typically uses vector-based (linear) environments whereas graphic-based software utilizes raster-based (pixelated) environments.4.What is computational simulation and can you give an example?Simulation is the imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system. The network computer games are typical example of computational simulation.5.How does computational simulation help engineering design?Combined with advances in CAD systems, it will be possible for mechanical engineers to collaborate in immersive interactive environments where they can design collaboratively,test hypothesis, run models and simulations and observe their creations in three dimensions much as an engineer can observe a car being built with their colleagues on the shop floor.Section C Post-reading TaskReading Comprehension1.

科技英语课文翻译及课后答案

第一单元自动化第二部分阅读A自动化的含义“自动化”已经是,而且现在仍然是,一个被大量滥用的词。

但是,人们对其确切的意义以及所包括的内容,正在逐渐地有了较为正确的了解。

如果不是下一个定义的话,我也许可以尝试作些解释,把自动化说成是一个概念。

运用这个概念,人们通过对机器装置的性能进行充分的测量、观察和控制,从而使其以最高的效率运转。

这需要对这种装置的功能有一个详细而连贯性的了解,以便需要时便能运用最佳的矫正操作。

自动化按其确切的意义,只有全面运用通信、计算和控制三个主要组成部分(“三C" )才能完全实现。

我认为,确保人们对合为一体的三个组成部分对我们的社会所蕴含着的某些意义有所认识和了解,是很有必要的。

首先,我们不妨考虑工业部门之一的炼钢工业。

在炼钢工业中,自动化已经开始成型。

到过钢厂的人都会知道从高炉开始的各种工艺流程的一些情况,成品条钢或板钢生产出来之后,再准备送往制造工艺车间或汽车厂,这些工艺流程是相互链接的。

为了使工厂中各个车间充分发挥效率,可以使用计算机来控制每个车间。

在此之前,计算机工作所需要的一切资料均输入机内。

就高炉来说,需要给计算机提供装人高炉的原料的信息、高炉工作温度的信息和处理各种各样配料的最好方法等方面的资料。

钢厂的高炉操作是一项复杂而要求技术熟练的作业,需要大量的知识和大量的综合信息,并迅速地做出判定选择,以便确保高炉工艺流程中的下一阶段的有效工作。

计算机对所有这一切都了解得很透彻,能够做出非常大量的中间判定,并且能够把全部信息立刻和不间断地提供给管理人员,以使他们做出高效管理这个工厂所需要的最后决定。

由此产生的信息数据和判定要进行处理,然后转送到下一个工序。

在这里,对操作的一些专门细节再次进行整理,提出最佳和最终的判定,然后对这些信息再一次进行处理并输送给下一道工序。

同时,当信息数据从生产单元的一道工序输送到下一工序并完全结合成为一项新的操作时,每次变化的结果反馈到最初阶段,而且,不断地做进一步的调整,结果是整个工厂的工艺流程便能够高效率地进行下去。
