&&&& The world is getting smaller and smaller, but gaps between people have always existed and will continue to exist for the foreseeable future. Different sets of cultures, belief systems and
values have shaped today's world. To avoid misunderstandings, we need to learn not only
other languages, but the cultures behind the languages as well. To understand English-speaking people, we first need to understand their culture, history and way of life.
British and American Culture Reader
will give students a good general idea of life and culture in the United Kingdom and the United States.
&&&& The articles in this series vividly describe the structure of Western society from the
perspectives
(视角) of ordinary people - and their own experiences of life. As an American
living in the United Kingdom, I am in a better position to know what's best about American culture through the eyes of my British friends. Actually, all the articles in this series are written by native English speakers who have lived in the West for a significant period. This ensures that the text presents an accurate picture of life in the English-speaking world.&&
&&&& As a children's publisher, I know that young students in particular need lively lessons that
will engage their curiosity and desire to learn. Therefore, topics have been carefully chosen to include those of greatest relevance to children, including games, schools, clothes and festivals. && &The series also provides an interesting contrast of British and American culture, which gives
young Chinese readers an insight into the differences between them and therefore enables the students to better understand the two countries. Being aware that the teacher will pass on the information to students, the authors have made sure to present the text in a light-hearted and
fun way, with interesting stories inserted where appropriate.&& &&&& British and American Culture Reader is a reflection of our society. Readers of this series
will shake off the bad
stereotypes
(旧框框) that they hold about Westerners and may be surprised to find how similar Westerners' way of life is to their own in many ways. I hope
you enjoy reading the articles as much as I have enjoyed writing them.

Exploit your parking space
&&&& An unused parking space or garage can make money. If you live near a city center or an airport, you
could make anything up to ￡200 or ￡300 a week. Put an advertisement (广告) for free on Letpark or
Atmyhousepark.
Rent (出租) a room
&&&& Spare room? Not only will a lodger (房客) earn you an income, but also, thanks to the government- backed "rent a room" program, you won't have to pay any tax on the first ￡4500 you make per year.
Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
&&&&& Don't want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your
Live on set
&&&& Renting your home out as a "film set" could earn you hundreds of pounds a day, depending on the
film production company and how long your home is needed. A quick search on the Internet will bring
up dozens of online companies that allow you to register your home for free-but you will be charged if
your home gets picked.
Use your roof
&&&& You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment
(around￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused
energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier,
which could prevent you from changing the roof.

每局各次得分的总和叫做这一局的总积分、a（自然数）、108、0这三个数中的一个、104、107，每局可随意玩若干次、106，每次得分是8、105、109。小华曾得到过这样的总积分小华玩某种游戏，又知道他不可能得到“83分”这个总积分、110：103。问a是多少
要写出过程，不过最好别太复杂了
提问者采纳
3、13、29、5，a应是1，也有奇数、13、5、11、7、3、7、33、19分析与解答
1、19、53中的某一个奇数；110-21×4=26，要同时凑出106。因为110-21×2=68、17；21×6＞110、17、27，要凑出106。
由于103=8×8+3×13
105=8×5+5×13
106=8×10+2×13
107=8×2+7×13
108=8×7+4×13
109=8×12+1×13
110=8×4+6×13
因此、27中的某一个奇数，从上面的拆分来看、21这十个奇数中的某一个、9、13、75这十七个奇数中的任何一个、23、11、5，a只能是1、15，68÷8=8……4，8和110都是偶数、15、17，21是奇数.确定a
如果a=21，21应取偶数个、49、108这两个数，这八个数中、9、9、21，a只能是13或21、11、15、7、5、25，所以用21和8凑110时、43。由于
108=8×13+4 4=4×1
=8×12+12 12=4×3
=8×11+20 20=4×5
=8×10+28 28=4×7
=8×9+36 36=4×9
=8×8+44 44=4×11
=8×7+52 52=4×13
=8×6+60 60=4×15
=8×5+68 68=4×17
=8×4+76 76=4×19
=8×3+84 84=4×21
=8×2+92 92=4×23
=8×1+100 100=4×25
因为108是可得分数、17。
106=8×13＋2 2=2×1
=8×12+10 10=2×5
=8×11+18 18=2×9=6×3
=8×10+26 26=2×13
=8×9+34 34=2×17
=8×8+42 42=2×21=6×7=14×3
=8×7+50 50=2×25=10×5
=8×6+58 58=2×29
=8×5+66 66=2×33=6×11=22×3
=8×4+74 74=2×37
=8×3+82 82=2×41
=8×2+90 90=2×45=6×15
=10×9=18×5=30×3
=8×1+98 98=2×49=14×7
=8×0+106 106=2×53
因为106是可得分数，既有偶数，26÷8=3……2、37。
2、51、21、35、9，因此a必是奇数。
下面检验a=13是否满足题意、3，要凑出108。结合上面的分析可知、25，a不能是1。由于83=8×10+3 3=3×1
=8×9+11 11=11×1
=8×8+19 19=19×1
=8×7+27 27=3×19=27×1
=8×6+35 35=5×7=35×1
=8×5+43 43=43×1
=8×4+51 51=3×17=51×1
=8×3+59 59=59×1
=8×2+67 67=67×1
=8×1+75 75=3×25=5×15=75×1
因为83是不可得分数，从上面的拆分来看、7、15，a应是1、3，从上面的拆分来看、67。
结合上面的分析、25.由于103到110连续八个自然数都是可得分数，所以 a≠21、41、59、11、45，a=13是满足题意的唯一的解

&&&& Sorry to say, our brains naturally start slowing down at the Cruelty young age of 30. It used to be thought that this couldn't be helped, but new studies show that people of any age can train their brains
to work faster. "Your brain is a learning machine," says University of California scientist Dr. Michael Merzenich. Given the right tools, we can train our brains to act like they did when we were younger.
All that's required is the practice designed just for the purpose: a few exercises for the mind.
&&&& Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (). Since much of the data we receive comes through &&&& Over the course of training, the program starts asking you to distinguish (辨别) sounds (between "dog"
and "bog", for example) at an increasingly faster speed. It's a bit like tennis instructor, says Merzenich,
hitting balls at you ~faster and faster to keep you challenged (受到挑战). You may start out slow, but before long you're pretty quick.
&&&& The biggest finding in brain research in the last ten years is that
the brain at any age is highly plastic
you ask your brain to learn, it will learn. And it may even speed up while in the process.
&&&& To keep your brain young and plastic you can do one of a million new activities that challenge and excite you: playing table tennis or bridge, doing crossword puzzles, learning a language. "When it comes to preventing ageing, you really do 'use it or lose it'," says Barbara Sahakian, professor at Cambridge University.
1. Dr. Merzenich's training method mainly depends on ______.
A. speech training B. computer languages C. the activities one joins in
D. the information being dealt with
2. By saying "the brain at any age is highly plastic", the writer probably means the brain can be_____.
B. mastered
C. developed
D. researched
3. What can we learn from the text?
A. Practice makes a quick mind.
B. Brain research started ten yeas ago.
C. Dr. Merzenich is a scientist in computer. D. People believed nothing could stop the brain slowing down.
4. Which of the following agrees with the writer's idea?
A. The training methods work better for the old.
B. People should use the brain to stop it from ageing.
C. The training of the brain should start at an early age.
D. It's necessary to take part in as many activities as possible.
