                                                          Robot Revolution
    The day that a robot wakes you up,cleans your room and walks your dog might still be a few decades
off. But increasingly,engineers are saying that robots are going to make the leap from the factory floor to
your family room.
    Companies like Sony and General Electric are working on designs for small robots. Products like the
Roomba,a robot that can clean floors,are flying off the shelves. On the  cover  of  a  recent  issue  of  
Scienti fic  American Magazine,Bill Gates predicted the "Dawn of the Age of Robots".
      What's behind this new era ( 时代)?  It's partly a matter of technology. Devices that can recognize and
respond to a human voice have been developed. There are now a few different ways for robots to move
around. They can walk, crawl or ride on wheels. They are being made smaller and smaller. They are also
becoming more and more energy efficient.
        A bigger part of the story is on the demand side. From the day Robert Adler invented the television
remote control in the 1950s, people around the world have tirelessly searched for ways to get lazier.
     Also take into consideration the increasing wealth of
rich people,the time appears ripe to introduce robots to
ease our daily life.
      To be sure,robots that walk on two legs and talk like people are still too complex for our present
engineering abilities. Today's robot revolution is to make them for everyday use. Robots will do
basic- housework such as cleaning or gardening,or just help you have more fun on the basketball court.
   What makes a robot different from an ordinary cleaning machine is not the presence of computer chips( 芯片). Nowadays even your microwave has a computer chip. It is the ability to sense and make changes
to the environment in real time.
    For example,a floor-cleaning robot should be able to sense your scared cat and move out of the way.
Today's computing ability is, for the first time, able to make machines that could "think" at least in certain
limited
ways.

     Directions: Read the following passage. Fill in the numbered blanks by using the information for the
passage. Write NO MORE THAN 3 WORDS for each answer.

     A Low-Carbon Economy (LCE) refers to an economy which has a minimal emission of greenhouse gas
(GHG), namely, carbon dioxide into the biosphere (生物圈). Recently, most of the scienti sts and the public
hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere
due to human activities. The over-concentration of these gases is producing global warming that affects
long-term climate, with negative impacts on humanity in the foreseeable future. LCE, therefore, is proposed
as a means to avoid catastrophic climate change.
     All nations which are considered carbon intensive societies and societies which are heavily populated
should become zero-carbon societies and economies. Several of these countries have promised to become
'low carbon' but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions
rather than ceasing all emissions.
     Nuclear power and the strategies of carbon capture and storage (CCS) have been proposed as the primary
means to achieve a LCE while continuing to exploit non-renewable resources. Scientists are afraid, however,
whether the spent-nuclear-fuel can be stored, and whether it is secure. Also they are not certain about the
costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak
into the biosphere or not. Alternatively, many have proposed renewable energy should be the main basis of a
LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since
investment and production have been growing significantly in recent times. Furthermore, it has been proposed
that to make the transition to an LCE economically attractive we would have to attach a cost (per unit output)
to GHGs through means such as emissions trading and/or a carbon tax .
     A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to
power-generation around technologies that produce energy and materials with little GHG emission and thus
around populations, buildings, machines and devices which use those energies and materials efficiently and
dispose of or recycle its wastes so as to have a minimal output of GHGs.
