共用题干Learn about Light1 .Ancient civilizations were amazed by the existence of light for thousands of years. The Greek philosophers believed that light was made up of countless,tiny particles that enter the human eye and create what we call vision. However,Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them,light spread out and travelled like a straight line. This theory was accepted during the 19th century.2 .In 1905,Albert Einstein published a research paper in which he explained what is re-ferred to as the photoelectric effect. This theory explains that particles make up light.The particles Einstein was referring to are weightless bundles（束）of electromagnetic（电磁）energy called photons（光子）.Today,scientists agree that light has a dual（二重）nature一it is part particle and part wave. It is a form of energy that allows us to see things around us.3 .Things that give off light are known as sources of light. During the day,the primary source of light is the sun. Other sources of light include stars,flames,flashlights,street lamps and glowing gases in glass tube.4 .When we draw the way light travels we always use straight lines. This is because nor-mally light rays travel in a straight line. However,there are some instances that can change the path and even the nature of light. They are reflection,absorption,interference（干扰）, etc.5 .Physicists have attempted to measure the speed of light since the early times. In 1849, Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometers away and placed a rotating cogwheel（旋转齿轮）between the beam and the mirror. From the rate of rotation of the wheel,number of wheel's teeth and distance of the mirror,he was able to calculate that the speed of light is 313 million meters per second. In a vacuum（真空）,however,the speed of light is 299,792,458 meters per second. This is about a million times faster than the speed of an airplane.Paragraph 3______A: How Is the Nature of Light Explained Today?B: What Are Sources of Light?C: How Did Physicists Measure the Speed of Light?D: How Does Light Travel?E: How Did People Think of Light Years Ago?F: What Causes a Shadow?
共用题干第一篇Technology Transfer in GermanyWhen it comes to translating basic research into industrial success,few nations can match Germany.Since the 1940s,the nation's vast industrial base has been fed with a constant stream of new ideas and expertise from science.And though German prosperity （繁荣）has faltered（衰退）over the past decade because of the huge cost of unifying east and west as well as the global economic decline , it still has an enviable（令人羡慕的)record for turning ideas into profit.Much of the reason for that success is the Fraunhofer Society,a network of research institutes that exists solely to solve industrial problems and create sought-after technologies. But today the Fraunhofer institutes have competition.Universities are taking an ever larger role in technology transfer,and technology parks are springing up all over.These efforts are being complemented by the federal programmes for pumping money into start-up companies,Such a strategy may sound like a recipe for economic success,but it is not without its critics.These people worry that favouring applied research will mean neglecting basic science,eventually starving industry of fresh ideas.If every scientist starts thinking like an entrepreneur（企业家）,the argument goes , then the traditional principles of university research being curiosity-driven,free and widely available will suffer.Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years.While this debate continues,new ideas flow at a steady rate from Germany's research networks,which bear famous names such as Helmholtz,Max Planck and Leibniz.Yet it is the fourth network,the Fraunhofer Society,that plays the greatest role in technology transfer.Founded in 1949,the Fraunhofer Society is now Europe's largest organisation for applied technology,and has 59 institutes employing 12,000 people.It continues to grow. Last year,it swallowed up the Heinrich Hertz Institute for Communication Technology in Berlin.Today,there are even Fraunhofers in the U.S. and Asia.What factor can be attributed to German prosperity?A:Technology transfer. B:Good management.C:Hard work. D:Fierce competition.

The researchers expect that the results of this research will be integrated into computers within ten years .In the short term,the glass is already being developed and used in next-generation computer memory technology known as CRAM,which may ultimately be integrated with the advances reported. The result of the research can help computers to increase_________.A: optical informationB: processing speedsC: electronsD:positive chargesE: data technologiesF: all-optical systems
共用题干New Research Lights the Way to Super-fast Computers1. New research published today in the journal Nature Coniniunications,has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.2. The research by the University of Surrey,in collaboration with the University of Cambridge and the University of Southampton,has found it is possible to change the electronic properties of amorphous chalcogenides,a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping,the team of researchers have discovered a material that could use light to bring together different computing functions into one component,leading to all-optical systems.3. Computers currently use electrons to transfer information and process applications.On the other hand,data sources such as the Internet rely on optical systems:the transfer of information using light. Optical fibres are used to send information around the world at the speed of light,but these signals then have to be converted to electrical signal once they reach a computer,causing a significant slowdown in processing.4 .“The challenge is to find a single material that can effectively use and control light to carry information around a computer.

共用题干第二篇Medical JournalsMedical journals are publications that report medical information to physicians and otherhealth professionals.In the past,these journals were available only in print.With the development of electronic publishing, many medical journals now have Web sites on the Internet,and some journals are published only online.A few medical journals,like the Journal of the American Medical Association,are considered general medical journals because they cover many fields of medicine.Most medical journals are specialty journals that focus on a particular area of medicine.Medical journals publish many types of articles.Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments.Review articles summarize and analyze、the information available on a specific topic based on a careful search of the medical literature.Because the results of individual research studies can be affected by many factors,combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing,diagnosing or treating a particular disease.Case conferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the authors,often regarding a research or review article published in the same issue.Editorials provide a per- spective on how the current article fits with other information on the same topic.Letters to the editor provideit way for readers of the medical journal to express comments,questions or criticisms about articles published in that journal.The main readers of medical journals are_________.A:the general publicB:health professionalsC:medical criticsD:news reporters

You need to recommend a solution that meets the requirements of the corporate policy. Your solution must minimize hardware and software costs. What should you recommend？（）A、Create a new Active Directory site.
