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):

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

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:

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——科技类

科技类(1)With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five ye ars in a project called “Noah’s Ark”.Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s C ollege of V eterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.The entire procedure could take from three to five years to complete.“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pa ndas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”1. The aim of “Noah’s Ark” project is to _______.A. make efforts to clone the endangered pandasB. save endangered animals from dying outC. collect DNA of endangered animals to studyD. transfer the nuclear of one animal to another2. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.A. available panda eggsB. host animalsC. qualified researchersD. enough money3. The best title for the passage may be _______.A. China’s Success in Pandas CloningB. The First Cloned Panda in the WorldC. Exploring the Possibility to Clone PandasD. China —the Native Place of Pandas Forever4. From the passage we know that _______.A. Kraemer and his team have succeeded in cloning a dogB. scientists try to implant a panda’s egg into a rabbitC. Kraemer will work with Chinese scientists in clone researchesD. about two thousand of species will probably die out in a century【答案与解析】本文讲述中国正在竭力克隆濒临绝种的熊猫，这和Texas A & M University 的Noah's Ark(诺亚方舟)工程极为相似，都是想拯救濒临灭绝的动物。

科技英语阅读课后参考答案-Unit1,3

科技英语阅读课后参考答案-Unit1,3Unit 1 MathematicsPart I EST Reading Reading 1Warm-up Questions: Work in pairs and discuss the following questions. 1. Who is Bertrand Russell? Bertrand Arthur William Russell (b.1872 – d.1970) was a British philosopher, logician, essayist and social critic best known for his work in mathematical logic and analytic philosophy. His most influential contributions include his defense of logicism (the view that mathematics is in some important sense reducible to logic), his refining of the predicate calculus introduced by Gottlob Frege (which still forms the basis of most contemporary logic), his defense of neutral monism (the view that the world consists of just one type of substance that is neither exclusively mental nor exclusively physical), and his theories of definite descriptions and logical atomism. Russell is generally recognized as one of the founders of modern analytic philosophy, and is regularly credited with being one of the most important logicians of the twentieth century. 2. What is Russell’s Paradox? Russell discovered the paradox that bears his name in 1901, while working on his Principles of Mathematics (1903). The paradox arises in connection with the set of all sets that are not members of themselves. Such a set, if it exists, will be a member of itself if and only if it is not a member of itself. The paradox is significant since, using classical logic, all sentences are entailed by a contradiction. Russell's discovery thus prompted a large amount of work in logic, set theory, and the philosophy and foundations of mathematics. 3. What effect did Russell’s Paradox have on Gottlob Fregg’s system? At first Frege observed that the consequences of Russell’s paradox are not immediately clear. For example, “Is it always permissible to speak of the extension of a concept, of a class? And if not, how do we recognize the exceptional cases? Can we always infer from the extension of one concept’s coinciding with that of a second, that every object which falls under the first concept also falls under the second? Because of these kinds of worries, Frege eventually felt forced to abandon many of his views. 4. What is Russell’s response to the paradox? Russell's own response to the paradox came with the development of his theory of types in 1903. It was clear to Russell that some restrictions needed to be placed upon the original comprehension (or abstraction) axiom of naive set theory, the axiom that formalizes the intuition that any coherent condition may be used to determine a set (or class). Russell's basic idea was that reference to sets such as the set of all sets that are not members of themselves could be avoided by arranging all sentences into a hierarchy, beginning with sentences about individuals at the lowest level, sentences about sets of individuals at the next lowest level,1sentences about sets of sets of individuals at the next lowest level, and so on Using a vicious circle principle similar to that adopted by the mathematician Henri Poincaré, and his own so-called "no class" theory of classes, Russell was able to explain why the unrestricted comprehension axiom fails: propositional functions, such as the function "x is a set," may not be applied to themselves since self-application would involve a vicious circle. On Russell's view, all objects for which a given condition (or predicate) holds must be at the same level or of the same "type." 5. Have you ever heard of Zermelo-Fraenkel set theory.? Can you give an account of it? Contradictions like Russell’s paradox arose from what was later called the unrestricted comprehension principle: the assumption that, for any property p, there is a set that contains all and only those sets that have p. In Zermelo’s system, the comprehension principle is eliminated in favour of several much more restrictive axioms: a. Axiom of extensionality. If two sets have the same members, then they are identical. b. Axiom of elementary sets. There exists a set with no members: the null, or empty, set. For any two objects a and b, there exists a set (unit set) having as its only member a, as well as a set having as its only members a and b. c. Axiom of separation. For any well-formed property p and any set S, there is a set, S1, containing all and only the members of S that have this property. That is, already existing sets can be partitioned or separated into parts by well-formed properties. d. Power-set axiom. If S is a set, then there exists a set, S1, that contains all and only the subsets of S. e. Union axiom. If S is a set (of sets), then there is a set containing all and only the membersof the sets contained in S. f. Axiom of choice. If S is a nonempty set containing sets no two of which have common members, then there exists a set that contains exactly one member from each member of S. g. Axiom of infinity. There exists at least one set that contains an infinite number of members. With the exception of (b), all these axioms allow new sets to be constructed from already-constructed sets by carefully constrained operations; the method embodies what has come to be known as the “iterative” conception of a set. /doc/a90df7ed551810a6f524860e.html/entries/russell/ Section C Post-reading TaskReading Comprehension1.

Who discovered the Mandelbrot set? This is not a trick question, not easy to answer. Many people including Mandelbrot have laid claim to the discovery. 2. Why was the set named after Benoit B. Mandelbrot? The set is named after Benoit B. Mandelbrot, a mathematician at the IBM Thomas J. Watson Research Center because he coined the term fractal to describe phenomena (such as coastlines, snowflakes, mountains and trees) whose patterns repeat themselves at smaller and smaller scales. 3. Why has there been so much controversy about who discovered the Mandelbrot set?6Mandelbrot claims that he and he alone discovered the Mandelbrot set, but there are other mathematicians who have challenged his claim. 4. What did the challengers say about Mandelbrot’s claim of discovery? Two mathematicians said that they independently discovered and described the set at about the same time as Mandelbrot did. And another mathematician also asserted that his work on the set not only predated Mandelbrot's efforts but also helped to guide them 5. Why did some professors support Mandelbrot’s claim? Mandelbrot deserves to have the set named after him, because his efforts brought the set to the attention of both the public and of the pure-mathematics community.Section C Post-reading TaskReading and Understanding1. Choose the best summary of the passage. C A B D2. Complete the sentences based on the text. 1) The term Mandelbrot set is used to refer both to a general class of_________________ and to a particular instance of such a set. （fractal sets） 2) 2.In general, a Mandelbrot set marks the set of points in the _________________ such that the corresponding Julia set is connected and not computable. （complex plane） 3) "The" Mandelbrot set is the set obtained from the _________________ z_(n+1)==z_n︿2+c with z_0==c, where points in the complex plane for which the orbit of z_n tend to infinity are in the set. （quadratic recurrence equation） does not4) Setting z_0 equal to any point in the set that is not a _________________ gives the same result. （periodic point） 5) The Mandelbrot set was originally called a _________________ by Mandelbrot.

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。
