  Microchip Research Center Created
  A research center has been______(51)in this Far Eastern country to develop advanced microchip production technology.The center,which will start out with about US$14 million,will help the country develop its chip industry without always depending on imported technology.
  The center will make use of its research skills and______(52)to develop new technology for _______(53)chip plants.The advent of the center will possibly free the country from the_______(54) that it is always buying almost-outdated technologies from other countries,said the country's flagship chipmaker.______(55),chip plants in this country are in a passive situation because many foreign governments don't allow them to______(56)the most advanced technologies,fearing they will be used for______(57) purposes.Moreover,the high licensing fees they have to pay to technology providers are also an important _(58)for their decision of self-reliance.
  As mainstream chip production technology______(59)from one generation to the next every three to five years,plants with new technology can make more powerful chips at lower costs,while plants with______(60)equipment,which often cost billions of dollars to build,will be______(61)by the maker.
  More than 10 chip plants are being built,each costing millions of US dollars.The majority of that money goes to overseas equipment______(62)and technology owners-mainly______(63)Japan and Singapore.
  Should the new center play a major role in improving the situation in the industry,the country admits the US $14 million investment is still rather small.This country is developing______(64)technologies.Most of the investment will be spent on setting_______(65)with technology and intellectual property owners.

  Batteries Built by Viruses
  What do chicken pox,the common cold,the flu,and AIDS have in common?They're all diseases caused by viruses,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds.
  Not everyone runs from the tiny disease carriers,though. In Cambridge,Massachu- setts,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 engi-neer Angela Beicher,who first came up with the 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.
  Beicher's team includes Paula Hammond,who helps put together the tiny batteries,and
  Yet-Ming Chiang,an expert on how to store energy in the form of a battery.“We're 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 batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary batteries won't be small enough to fit in-side.
  The ideal battery will store a lot of energy in a small package. Right now,Belcher's model battery,a metallic disk completely built by viruses,looks like a regular watch battery. But inside,its components are very small一so tiny you can only see them with a powerful microscope.
  How small are these battery parts?To get some idea of the size,pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is一 pretty thin,right?Although the width of each person's hair is a bit different,you could probably fit about 10 of these virus-built battery parts,side to side,across one hair. These micro-batteries may change the way we look at viruses.
  What is Belcher's team doing at present?
  A: It is finding ways to get rid of viruses.
  B: It is mass-producing micro-batteries.
  C: It is making batteries with viruses.
  D: It is analyzing virus genes.

  A company in Phoenix,Arizona,says that it can now clone your cat."Actually,"said Felix Lee,President of Twice Is Nice,Inc.,"you don't even have to wait until your beloved cat dies. (46)______."
  The price is steep.A clone of your cat will cost $50,000.First,(47)______.This is sent to TwIN,Inc.,where it is cultured to grow fresh new cells.These new cells are stored in liquid nitrogen until you notify TwIN,Inc.,that you are ready for the clone.(48)______.A cultured cell is implanted into a female cat that is in estrus,and(49)______,a kitten is born about 60 days later. The new kitten is weaned in about eight weeks.TwIN,Inc.delivers the kitten to you after it receives the remaining $25,000.
  "We are a growing company,"said Lee."Our facility can handle about a dozen births a year now,but our goal is to produce about 50 kittens and 50 puppies a year."The company is currently experimenting with stray dogs.Some canine clones seem to be perfect,but some have been bizarre. Nevertheless,(50)______.
  _________（50）
  A:At this time,you pay half the amount($25,000)
  B:if all goes well
  C:We already have clients whose clone lives with its donor
  D:your veterinarian must do a biopsy of your cat
  E:Many pet owners have benefited from cloning technology
  F: Lee believes that they will be successfully cloning dogs in about a year

  Electric Backpack
  Backpacks 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 that makes electricity from
  energy produced while its wearer walks.In military actions,search-and-rescue operations,and scientific field
  studies,people rely increasingly on cell phones,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.Science.
  The backpack's electricity-creating powers depend on springs 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!
  According to Paragraph 4,what does Rome plan to do?
  A:To make the backpack more 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 a newspaper or on television.
