play a role．

Crystal Ear
    One day a friend asked my．wife Jill if I wanted a hearing aid．“He certainly does．”replied
Jill．After hearing about a remarkable new product．Jill finally got up the nerve to ask me if I’d
ever thought about getting a hearing aid．“No way,”I said．“It would make me look 20 years
older．”  “No。no。”she replied．”This is entirely different．It’s Crystal Ear!”

 and adjustments to fit your ear．Thanks to Crystal Ear，the“sound solution”is now convenient．
Almost 90 percent of people with mild hearing loss，and millions more with just a little hearing
 drop-off(下降)，can be dramatically helped with Crystal Ear．More over, its superior design is
energy-efficient，so batteries can last months．Crystal Ear is now available to help these people
treat their hearing loss with a small hearing amplifier(放大器)．

Technology Transfer in Germany
    when 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 1t is not without its crities,
These people worry that favouring applied research will mean neglecting basic science，
eventually starving industry of flesh 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 1 2，000 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 US and Asia．
41 What factor can be attributed to German prosperity?
  A Technology transfer．
  B  Good management．  
  C Hard work．
  D  Fierce competition．
42 Which of the following is NOT true of traditional university research?
    A  It is free．
    B  It is profit-driven．
    C  It is widely available．    ．
    D  It is curiosity—driven．
43 The Fraunhofer Society is the largest organisation for applied technology in
    A  Asia．
    B  USA．
    C  Europe．
    D  Africa．
44 When was the Fraunhofer Society founded?
    A  In 1940.
    B   Last year．
    C  After the unification．
    D  In 1949.
45 The word “expertise’ ’in line 3 could be best replaced by
  A  “experts”．
  B  “scientists”．
  C  “scholars”．
  D  “special knowledge”．

Conservation or wasted Effort?
  The black robin(旅鸫)is one of the world’s rarest birds．It is a small，wild bird，and it lives
only on the island of Little Mangere，off the coast of New Zealand．In 1967 there were about
fifty black robins there；in 1977 there were fewer than ten．
Energetic steps are being taken to preserve the black robin．——(47)The idea is to
buy another island nearby as a special home，a“reserve”，for threatened wild life，including
black robins．The organizers say that Little Mangere should then be restocked(重新准备)with
the robin’s food．Thousands of the required plants are at present being cultivated in New
Zealand．
    Is all this concern a waste of human effort?
what is reasonable and what is unreasonable?
(48)Are we losing our sense of
  In the earth’s long，long past hundreds of kinds of creatures have evolved，risen to a degree
of success and died out．In the long，long future there will be many new and different forms of
life．Those creatures that adapt themselves successfully to what the earth offers will survive for a
long time．——(49)This is nature’s proven method of operation．
  The rule of selection--“the survival of the fittest”—-is the one by which human beings have
themselves arrived on the scene．We，being ode of the most adaptable creatures the earth has yet
produced，may last longer than most．——(SO)You may take it as another rule that when，
