It was once common to regard Britain as a society with class distinction. Each class had unique
characteristics.
In recent years, many writers have begun to speak the 'decline of class' and 'classless society' in
Britain. And in modern day consumer society everyone is considered to be middle class.
But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found
90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital
part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not
be culturally and politically obvious, yet it remains an important part of British society. Britain seems to
have a love of stratification.
One unchanging aspect of a British person's class position is accent. The words a person speaks tell
her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂was viewed as the most attractive voice. Most people said this accent sounded 'educated' and 'soft'. The
accents placed at the bottom in this study, on the other hand, were regional city accents. These accents were
seen as 'common' and 'ugly'. However, a similar study of British accents in the US turned these results
upside down and placed some regional accents as the most attractive and BBC English as the least. This
suggests that British attitudes towards accent have deep roots and are based on class prejudice.
In recent years, however, young upper middle-class people in London, have begun to adopt some
regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed.
However, the 1995 pop song 'Common People' puts forward the view that though a middle-class person
may 'want to live like common people' they can never appreciate the reality of a working-class life.
21. A recent study of public opinion shows that in modern Britain ________.
A. people regard themselves socially different
B. most people belong to middle class
C. it is easy to recognize a person’s class
D. it is time to end class distinction
22. The word “stratification” in Paragraph 3 is closest in meaning to ________.
.
A.variety B. qualification C. authority D. division
23. British attitudes towards accent ________.
A. are based on regional status B. have a long tradition
C. are shared by the Americans D. have changed in recent years
24. What is the main idea of the passage?
A. The middle class is expanding B. A person’s accent reflects his class
C. Class is a key part of British society D. Each class has unique characteristics.

If you could have a superpower, what would it be? Other than flying and communicating with
someone from his mind (which, let’s be honest, would probably actually be awful), breathing underwater is
one of the favorites. You can hang out with Aquaman and Ursula, and when the end of the world comes and
we’re all living under water, you’ll be fine.
With this in mind, a student at the Royal College of Art, London has designed a 3D-printed
amphibious garment called AMPHIBIO — essentially a set of gills(鳃) — for this very purpose.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂According to Jun Kamei, a biomimicry designer and materials scientist, it is "for a future where
humankind lives in the water".
With the world set for a global temperature increase of 3.2°C (5.7°F) by 2100, rising sea levels are a
very real threat to large coastal cities, potentially affecting up to 2 billion people — or 26 percent of the
current global population.
Kamei’s little device uses a specially designed porous(多孔的) material that fills oxygen again in the
water and releases carbon dioxide. It is inspired by water-diving insects that create their own little scuba
diving set by creating a protective bubble of air around their body thanks to their water repellent(防水的)
skin.
The technology is easily 3D-printable too, which will be great when we need them together. These
"gills" could replace heavy and clumsy scuba equipment, making it more similar to free diving but for
longer. This could have immediate applications for underwater rescue plans — the 12 boys rescued by
divers from a flooded cave in Thailand, for example, where it took weeks to work out how to get the boys
and the vital breathing equipment through those narrow tunnels.
So far, the tech has only been tested as a working prototype, not actually on humans, so the dream may
have to be on hold for now. And scaling up and testing on humans is Kamei’s next plan. This may sound
unbelievable, but Kamei insists he has a much more optimistic vision of the future.
25. What can be inferred about Aquaman and Ursula?
A. They can read minds. B. They can breathe underwater.
C. They often cause huge disasters. D. They can’t live underwater.
26. What can we learn about AMPHIBIO?
A. It can produce oxygen in the water.
B. Its user can communicate with others from their mind.
C. It is the unique useful tool against the threat of rising sea levels.
D. The designer drew his inspiration from a certain natural species.
27. Why did the author mentioned the rescue of the boys in Thailand?
A. To present the success of the new device.
B. To compare the new device with the old one.
C. To prove the advantage of the new device.
D. To show the new device is easily 3D-printable.
28. What is the author’s attitude to the future of the new design?
