Unit 3 Under the sea
突破阅读理解
怎样快速捕捉主题句(三)
【方法技巧】
主题句位于however，but，yet等信息词后。你要明白，
作者在文章中突然使用了表示转折意义的副词或连词时，
就表示作者的写作重心是在后面，而不是前面。所以，
抓住这些信息词能使你快速捕捉住主题句。
【实例验证】
In the West，having a successful lifestyle often means
having material goods such as a large house (or two)，a
large car (or two)，private schooling for the children，
designer clothes，foreign holidays in exotic locations
(winter and summer)，all mod cons (现代化设备)．
However，it could be argued that this emphasis on financial and material success can lead to people
becoming locked into (受困于) an unfulfilling lifestyle，
though a luxury one，working harder and harder to
become more and more successful financially in order
to buy more and more luxury items.
◆What does the author want to tell us in this paragraph?
A．The advantages of success.
B．The disadvantages of success.
C．A successful lifestyle.
D．Hard work leads to successful life.
答案：B
【实践应用】
Imagine you’re at a party full of strangers.You’re nervous.
Who are these people? How do you start a conversation?
Fortunately，you’ve got a thing that sends out energy at tiny
chips in everyone’s name tag (标签)．The chips send back name， job，hobbies， and the time available for meeting—whatever.
Making new friends becomes simple.
This hasn’t quite happened in real life.But the world is
already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product，
under your pet’s skin，even under your own skin.Passive
RFID tags have no energy source—batteries because they
do not need it.The energy comes from the reader，a scanning
device(装置)，that sends out energy (for example，radio
waves)that starts up the tag immediately.
Such a tag carries information specific to that object，
and the data can be updated.Already，RFID technology is
used for recognizing each car or truck on the road and it
might appear in your passport.Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s
medical records.At a nightclub in Paris or in New York the
same chip gets you into the VIP (very important person)
section and pays for the bill with the wave of an arm.
Take a step back: 10 or 12 years ago，you would have
heard about the coming age of computing.One example
always seemed to surface: Your refrigerator would know
when you needed to buy more milk.The concept was that
computer chips could be put everywhere and send
information in a smart network that would make ordinary
life simpler.
RFID tags are a small part of this phenomenon.“The
world is going to be a loosely coupled set of individual small
devices，connected wirelessly，” predicts Dr.J.Reich.Human
right supporters are nervous about the possibilities of such
technology.It goes too far tracking school kids through RFID tags，they say.We imagine a world in which a beer company
could find out not only when you bought a beer but also when
you drank it.And how many beers.Accompanied by how many
biscuits.
When Marconi invented radio，he thought it would be
used for shiptoshore communication，not for pop music.
Who knows how RFID and related technologies will be used
in the future.Here’s a wild guess: Not for buying milk.
◆The article is intended to________.
A．warn people of the possible risks in adopting RFID
technology
B．explain the benefits brought about by RFID technology
C．convince people of the uses of RFID technology
D．predict the applications of RFID technology
答案：D
