疑难语句细解
1．...a large wiselooking turtle was passing so close to me that
I could have touched it.一只长相聪慧的大海龟紧贴着我的
身旁游过，几乎伸手便可触及。
【要点指南】 could have done sth. 意为“本来能做某事(却
没做)”，表示一种责备、埋怨或训斥等语气，与should
have done sth.的意思差不多。另外，might have done
sth.“本来会做某事(却没做)”也表示同样的语气。
I could have lent you the money.Why didn’t you ask me?
我本来可以把钱借给你的，你为什么没有向我借呢？

You could have warned me she was coming.
你本应该告诉我她要来的。
拓展 could have done与might have done 也可表示推测语
气，意为“可能做了某事”，could多用于否定句或疑问句
中，这时与can have done和may have done用法相同。
She couldn’t/can’t have been to London，for she knows
nothing about it.
她不可能去过伦敦，因为她对伦敦一无所知。
He might/may have gone to sleep，for the light is turned
off.他可能已睡觉了，因为灯已熄灭。

2．The water was quite shallow but where the reef ended，
there was a sharp drop to the sandy ocean floor.水很浅，
但到了珊瑚礁的尽头，就有一个陡坡，一直降到满是沙
子的海底
【要点指南】 where此处引出地点状语从句。地点状语
从句一般放在主句之后，但在一些谚语中或表示抽象意
义的句子中，常把地点状语从句放在主句之前。此时的
where大体相当于in/at the place where，所以不可象引
导定语从句的where那样换成in/at which。
Please stay where you are.请你待在原地。

You must keep the little child where you can see him.
你要让这个小孩待在你能看得见他的地方。
Don’t leave the medicine bottle where the children can
get it.
不要把药瓶放在孩子们够得着的地方。
Where there is a will，there is a way.有志者，事竟成。
Where others are weak，he is strong.
别人的弱点正是他的优势。

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
