第二十九篇:I'll Be BachComposer David Cope(第1题关键词)is the inventor of a computer program that writes original works of classical music(第1题答案出处).It took Cope30years to develop the software.Now most people can't tell the difference区别between music by the famous著名的German composer作曲家J.S.Bach(1685--1750)and the Bach-like类似巴赫compositions作品,from Cope's computer.作曲家大卫·科普发明了一个计算机软件,它能编写出古典音乐的原创作品。

科普花了30年才完成这个软件。

现在,科普的计算机写出的作品与德国著名作曲家J.S.巴赫写的作品很相似,很少有人能分辨出其中的不同。

It all started in1980in the United States,when Cope(第2题关键词)was trying to write an opera(第2题答案出处).He was having trouble thinking of new melodies,so he wrote a computer program程序to create the melodies旋律.At first this music was not easy to listen to.What did Cope do?He began to rethink how human beings compose music.He realized that composers'brains work like big databases.First,they take in all the music that they have ever heard.Then they take out the music that they dislike.Finally,they make new music from what is left. According to Cope,only the great composers(第3题关键词)are able to create the database accurately,remember it,and form new musical patterns模式from it. (第3题答案出处)Cope built a huge database of existing music.He began with hundreds of works by Bach.The software analyzed the data:it broke it down into smaller pieces and looked for patterns.It then combined the pieces into new patterns.Before long,the program could compose short Bach-like works.They weren't good,but it was a start.科普根据现有的音乐建立了庞大的数据库。

2020职称英语考试《理工类》B级阅读理解专项模拟题(3)

2020职称英语考试《理工类》B级阅读理解专项模拟题(3)Using HIV Virus to Cure CancerScientists are planning to use human immunodeficiency(免疫缺陷)virus(HIV), one of mankind’s most feared viruses, as a carrier of genes which can fight cancer and a range of diseases that cannot be cured. The experts say HIV has an almost perfect ability to a void the body’s immune(免疫的)defenses, making it ideal for carrying replacement genes into patients’ bodies, according to the Observer.A team at the California-based Salk Institute, one of the world’s leading research centers on biological sciences, has created a special new breed of HIV and has started negotiations with the US Food and Drug Administration(FDA)to begin clinical gene therapy(治疗) trials this year. The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have” far wider applications”.The plan remains very likely to cause controversy sinceit involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was “shocking” but the fierce nature of HIV had disappeared by having all six of the potentially deadly genes removed.Illnesses such as various cancers are caused when a gene in a patient’s body fails to work properly. In the past two years, breakthroughs in genetics(遗传学)have led gene therapy scientists to try and replace the genes that do not function normally.Unfortunately, the body’s immune defense s have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier.The HIV virus has the ability to escape from, and then destroy, the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients’ bodies.16 FDA has approved the plan of using HIV to cure cancer in humans.A RightB WrongC Not mentioned17 The idea of using HIV for a beneficial purpose has been widely accepted.A RightB WrongC Not mentioned18 HIV can be safely used to cure cancer only if the deadly genes have been removed.A RightB WrongC Not mentioned19 The HIV virus is an excellent warrior to fight the body’s immune cells.A RightB WrongC Not mentioned20 Other countries are also expected to begin clinical gene therapy trials soon.A RightB WrongC Not mentioned21 It is the lack of money that has held up the progress in using replacement genes to cure cancer.A RightB WrongC Not mentioned22 The HIV virus has caused more deaths in developed countries.A RightB WrongC Not mentioned答案:16.B 17.B 18.A 19.A 20.C 21.B 22.C。

第一篇Smart WindowsWindows not only let light in to cut downon electricity use for lighting, but thelight coming through the window also provides heat. However, windows are notsomething people typically associate with an advanced technology. Reseachersare now working on new technologies that enable a window to quickly change fromclear to dark and anything in between easily.“It took us a long time to figure out whata window really is,”says Claes Granqvist. He’s a professor of solid-statephysics at Uppsala University in Sweden. “It contact with the outside world.You have to have visual contact with the surrounding world to feel well.” So,windows and n atural light are important for improving the way people feel whenthey’re stuck indoorsYet. windows are the weak link in abuilding when it comes to energy and temperature control. In winter cold airleaks in. When it’s hot and sunny, sunlight streams in. All of this sunlightcarries lots of heat and energy. And all of this extra heat forces people toturn on their conditioners. Producing blasts of cold air, which can feel so refreshing(使人清新的),actually sucks up enormous amountsof electricity in buildings around the world.Windows have been a major focus of energyresearch for a long time. Over the years, scientists have come up with a varietyof strategies for coating, glazing (用玻覆盖),and layeringwindows to make them more energy efficient. Smart windows go a step further.They use chromogenic (发色的)technologies which involve changes of color.Electrochromic (电致色的)windows use electricity tochange color. For example, a sheet of glass coated with thin layers of chemicalcompound such as tungsten oxide (氧化钨)works a bit like a batter. Tungsten oxides is clear when anelectric charge is applied and dark when the charge is removed, that is, whenthe amount of voltage(电压)is decreased, the window darkens until it’s completely dark afterall electricity is taken away. So applying a voltage determines whether thewindow looks clear or dark.One important feature that makes a smartwindow so smart is that it has a sort of“memory”. All it takes is a small changeof voltage to turn the window from one state to the other. Then, it stays thatway. Transits take anywhere from in10 seconds to a few minutes, depending onthe size of the window. The development of smart windows could mean thatmassive air conditioning systems may no longer be needed. “In thefuture,”Granqvist says, “our buildings may look different.”31. Which of the following of values ofwindows is NOT mentioned?A. Theylet light in to brighten the house.B. Theylet light in to heat the house.C. Theylet us have visual contact with the surrounding world.D. They let us think about the outside world.答案:D32. The expression “when it comes to “ inParagraph 3 is used toA. signalthe arrival of a guest.B. indicatethe recovery of consciousness.C. show our understanding of something.D. introduce a new aspect of a topic.答案:D33. According to Paragraph 4, smart windowsare the windows thatA. are coated.B. are glazed.C. have several layers.D.can change color.答案:D34. Whichparagraph gives an account of the way electrochromic windows……A. Paragraphs 5.B. Paragraph3.C. Paragraph4.D. Paragraphs6.答案:A35. Asmart window is smart mainly becauseA. itcan change its size.B. itcan change its structure.C. itcan change the voltage of electricity.D. it has a sort of memory.答案:D。

请根据短文内容,为每题确定l个最佳选项。

第一篇The Issue of PackageMaybe everyone has such an experience that you have to unwrap several layers of packaging when you enjoy a piece of candy. But this overuse of wrapping is not confined to luxuries. It is becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.The package itself is of no interest to the shopper, who usually throws it away immediately. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment.Recycling is already happening with milk bottles which are returned to the dairies, washed out,and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles.The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handyplastic packs.It is evident that more research is needed into the recovery and reuse of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.31. "This overuse of wrapping is not confined to luxuries. " (Line 2, Paragraph 1) means __________.A. more wrapping is needed for ordinary productsB. more wrapping is used for luxuries than for ordinary productsC. too much wrapping is used for both luxury and ordinary productsD. the wrapping used for luxury products is unnecessary32. Packaging is important to manufacturers because __________.A. it is easy to use it againB. shoppers are interested in beautiful packagingC. they want to attract more shoppersD. packaged things will not go rotten33. According to the passage, dairies are __________.A. experimenting with the use of paper bottlesB. giving up the use of glass bottlesC. increasing the use of plastic bottlesD. re-using their paper containers34. Some environmentalists think that __________.A. plastic packaging should be made more convenientB. no alternative can be found to plastic packagingC. too much plastic is wastedD. shops should stop using plastic containers35. The author thinks thatA. packing is actually useless and could be ignoredB.people will soon stop using packaging altogetherC.enough research has been done into recyclingD.it is better to produce new materials than to re—tlSe old ones第二篇Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change of clothes leaving your hands free to do other things. Someday, if you don't mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass. have invented a backpack thatmakes electricity from energy produced while its wearer walks. In military actions search-and-rescue operations and scientific field studies, people rely increasingly on cellphones global positioning system (GPS) receivers,night-vision goggles, and other battery powered devices to get around and do their work. The backpack's electricity-generating feature could dramatically reduce the amount of a wearer's load now devoted to spare batteries, report Rome and his colleagues in the Sept.9 science.The backpack's electricity-creating powers depend onsprings used to hang a cloth pack from its metal frame. The frame sits against the wearer's back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack's oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren't on the market yet, but if you do get one eventually just make sure to look both ways before crossing the street!36. Backpacks are convenient because __________.A o they can be verylargeB. they can hold as many things as you want to carryC. your handsare freed to do other thingsDo you do not have to carry things withyou37. What is the most important feature of the backpack invented byLawrence C.Romeand his colleagues?A. It produces electricity forelectronic devices while the wearer walks.B. It can be used as cellphones, GPS in the military actions or field studies.C. It is small andconvenient.D. It is light and easy to carry.38. The word "'springs" in Paragraph 3 means __________.A. a small stream of water flowing naturally from theearthB. the season of the year, occurring between winter and summerC. the act or an instance of jumping or leapingD. a length of metal woundaround, which returns to its original shape afterbeing pushed39. According to Paragraph 4, what does Rome plan to do?A. To make the backpackmore comfortable for the wearer.B. To put the backpack on the market.C. To test the advantage of the backpack.D. To promote the backpack in anewspaper or on television.40. What is implied in "if you do get oneeventually, just make sure to look bothways before crossing the street!"?A. You will be too excited to watch the traffic.B. Enjoyingelectronic devices while walking may invite traffic accidents.C. It is notpossible for you to get such a backpack.D. It is wise of you to have such abackpack.第三篇Invisibility RingScientists can't yet make an invisibility cloak like the one that Harry Potter uses. But, for the first time, they've constructed a simple cloaking device that makes itself and something placed inside it invisible to microwaves.When a person "sees" an object, his or her eye senses many different waves of visible light as they bounce off the object. The eye and brain then work together to organize the sensations andreconstruct the object's original shape. So, to make an object invisible, scientists have to keep waves from bouncing off it. And they have to make sure the object casts no shadow. Otherwise, the absence of reflected light on one side would give the object away.Invisibility isn't possible yet with waves of light that the human eye can see. But it is now possible with microwaves. Like visible light, microwaves are a form of radiant energy. They are part of the electromagnetic spectrum, which also includes radio waves, infrared light, ultravioletmys, X rays, and gamma rays. The wave lengths of microwaves are shorter than those of radio waves but longer than those of visible light.The scientists' new "invisibility device" is the size of a drink coaster and shaped likearing. The ring is made of a special material with unusual ability. When microwaves strike thering, very few bounce off it. Instead, they pass through the ring, which bends the waves all the way around until they reach the opposite side. The waves then return to their original paths.To a detector set up to receive microwaves on the other side of the ring, it looks as if the waves never changed their paths as if there were no object in the way! So, the ring is effectively invisible.When the researchers put a small copper loop inside the ring, it, too, is nearly invisible.However, the cloaking device and anything inside it do cast a pale shadow. And the device works only for microwaves, not for visible light or any kind of electromagnetic radiation. So, Harry Potter's invisibility cloak doesn't have any real competition yet.41. Harry Potter is mentioned in the passage, because scientists __________.A. can now make an invisible cloak of the same kind as he usesB. try to make an invisible cloak of the same kind as he usesC. try to invent a device similar in idea to the invisible cloak he usesD. know that it is possible to make an invisible cloak of the same kind42. What is true of microwaves?A. Their wavelengths are shorter than those of visible light.B. Their wavelengths are longer than those of visible light.C. They are different from visible light as they are a kind of radiant energy.D. They are visible to the human eye.43. What is NOT true of the invisibility device?A. It is made of a special material with unusual ability.B. Microwaves bounce off it when they strike it.C. Microwaves pass through it when they strike it.D. It bends the microwaves all the way around until they reach the opposite side.44. What does the word "coaster" mean in the passage?A. A disk or plate placed under a drinking glass to protect a table top.B. A vessel engaged in coastal trade.C. A roller coaster.D. A resident of a coastal area.45. Harry Potter's invisibility cloak doesn't have any real competition yet, because __________.A. scientists have not found out how his cloak worksB. the cloaking device is a total failureC. the cloaking device works only for microwavesD. the cloaking device works only for visible light 【2017年理工类职称英语B级模拟试题(阅读理解)】。

这里要首先来给大家解释一下这句话的含义:(1) 两头围堵:所谓的两头围堵也就是阅读理解备考的两个方向一方面,就是熟悉考试中阅读理解题型所必须要掌握的技巧—查读法。

查读法不仅仅是要会用,还要运用熟练,要在考试紧迫的时间中运用自如,才能够顺利的面对职称英语考试。

另一方面,就是要熟悉我们给大家的准备的冲刺点题。

我们的冲刺点题历年来都会比较准确的押中最后考试中出现的阅读理解文章,所以这部分一定要足够重视,不仅仅熟悉题目,更是要熟悉文章。

当然,这部分内容,我们就会在下节课来给大家详细的讲解了。

(2) 重点攻防:这个也要从两方面理解,一方面是攻,一方面是防。

攻,不用说,就是做好考试的准备,也就是我们说的围堵的两个方面,做好最充足的准备去面对职称英语考试。

防,这里也是要做好准备,考试中有时候会遇到时间紧,题目难度大。

也可能会出现押中的文章有一些变化,那么我们就要对这种变化做好准备, 正确在这种情况下多拿一些分数。

这个我们也会仔细的给大家的讲解,在今天的课程中,我们就会在最后教给大家如何在时间不够,或者是题目实在不会的情况下,怎么去尽量的蒙对题目。

二、常规解题技巧—查读法1.第一步-查找信息词我们可以按照下面的口诀来进行记忆:特殊:专有名词,数字,年份,特殊符号依次排开,错落有致。

普通:冠词为首,介词是帮手,所有格和后缀紧紧跟着走。

理工B级幺建华老师押题整理阅读理解第三十二篇Mind-reading 1Machine(B级)A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what’s happening in their brains.When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons are responsible for this processing.The fMRI (functional Magnetic Resonance Imaging)2 brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize3which parts of the brain receive more oxygen-rich blood —and therefore, which parts are working to process information.An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers’ brain activity with each photograph th ey looked at. Different objects caused different regions of the volunteers’ brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.词汇:scan /skAn/ v. &n. 扫描neuron /5njuErCn/ n. 神经元visualize /5vIzjJElaIz/ v.使可见;设想注释:1. Mind-reading: 能读出(猜出)人的想法的。

mind-read: 可做动词,如,As a successful salesman, he is able to mind-read his customers.2. FMRI(functional Magnetic Resonance Imaging):功能性磁振造影。

这是一种新兴的神经影像学方式,其原理是利用磁振造影来测量神经元活动所引发之血液动力的改变。

3. visualize: 意为make(something)visible to the eye,即“使可见,使显现”。

练习:1. What is responsible for processing the information sent by your eyes?A)A small region of the brain.B)The central part of the brain.C)Neurons in the brain.D)Oxygen-rich blood.2. Which of the following statements is NOT meant by the writer?A)Ceils in your brain are called neurons.B)The more oxygen a neuron consumes, the more blood it needs.C)fMRI helps scientists to discover which parts of the brain process information.D)fMRI helps scientists to discover how the brain develops intelligently.3. “Highlighting the areas of the brain at work” meansA)“marking the parts of the brain that are processing information”B)“giving light to the parts of the brain that are processing information” C)“putting the parts of the brain to work”D)“stopping the parts of the brain from working”4. What did the researchers experiment on?A)Animals, objects, and fruits.B)Two volunteers.C)fMRI machines.D)Thousands of pictures.5.

They’re all disease caused by viruses,tiny microorganisms that can pass from person to person.It's no wonder1 that when most people think about viruses, finding ways t0steer clear of2 viruses is what's on people's minds.Not everyone runs from the tiny disease carders, though3.In Cambridge, Massachusetts4, scientists have discovered that some viruses can be helpful in an unusual way.They are putting viruses to work, teaching them to build some of the world's smallest rechargeable batteries.Viruses and batteries may seem like an unusual pair,but they're not so strange for engineer Angela Belcher,who first came up with5the idea.At the Massachusetts Institute of Technology (MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways.In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques.Belcher's team includes Paula Hammond,who helps put together the tiny batteries,“We’re and Yet-Ming Chiang, an expert on how to store energy in the form of a battery.working on things we traditionally don’t associate with nature.” says Hammond. Many batteries are already pretty small.You can hold A.C and D batteries6 in your hand.The coin—like batteries that power watches are often smaller than a penny.However。
