Listening on Page 62
Mobile phones are now an important
part of everyday life. There has been a
film made about the effect they can ha
ve on your life (Cellphone directed by
Feng Xiaogang).
Read these questions before listening and discuss them in pairs.
1. What functions are already included on
a mobile phone?
2. Which ones do you find useful?
3. What else do you expect a mobile
phone to do for you?
□ a mobile that “think”
□ a mobile that spends your money
□ a mobile that can teach you English
□ a mobile that plans your holiday
Listen to the tape and tick the
descriptions you have heard.

Listen to the tape again and answer these questions.
1. Which mobile does Ruth think she will
buy and why?
Ruth wants to buy the mobile that turns
itself on when it receives important
calls. She missed three yesterday when
her mobile was switched/turned off.
2. What extra applications do
mobiles have now?
Mobiles can videotape and act as a
computer now.
3. What extra applications will they
have with the 3G mobiles?
They will be able to plan holidays,
book air tickets, hotel and an
appropriate place to stay. They will
authorize paying for them too.
4. Why is Ruth worried?
Ruth is worried because it might spend
her money.
5. What advantages do the 3G mobiles
offer?
The advantages are that they help
people who are busy at work to order
goods at the cheapest price or book
holidays, air tickets, etc.
6. What do you think might go wrong?
The mobile may spend money
unwisely or spend more than a
person can afford. You may forget
the spending and not include it in
your accounts or your personal
income.

Listen to the tape and decide if
you agree with the people on the tape.
What do you think it was? Before you
listen to the tape, get to know some
new words in the listening text.

the picture seems to show a
vehicle that can move backwards and
forwards, has four wheels and can take
people for a ride. It does not have beds or
room for beds, so it cannot be a caravan.
It is made of metal, so it cannot be a tent.
It does not go round and round, so it
cannot be a roundabout.
Look at these Chinese inventions
and in pairs discuss what you know
about them.
Look at these Chinese inventions
and in pairs discuss what you know
about them.
Think about what they were used for
and when they were invented. Collect
the information by doing some
research. Fill in the chart and prepare
to talk about one of the inventions to
the class.
What was its possible use? Why?
When and where did it appear in Europe?
1 An abacus is used to calculate mathematical problems including equations. It is more efficient than using the brain alone.
It was never used in the West, but it is closest in function to a modern personal calculator.
What was its possible use? Why?
When and where did it appear in Europe?
2 The printing press was used to print messages from the Emperor to the people. It helped the efficiency of government.
Gutenburg (1398-1468) began to print books on his press about 1450 AD in Germany.
What was its possible use? Why?
When and where did it appear in Europe?
3 The south pointer was used to find the most harmonious position to place new buildings. It seems possible that it dates back to the Qin Dynasty. It was the first application of magnetism in people’s lives.
The navigational compass appeared in Europe in the 12th or 13th centuries. This is similar to the time when Zheng He used it on his voyages to Africa.
You have been asked to write an
entry for an encyclopedia about one of
these three Chinese inventions. Choose
one and prepare to write your report.
You will include a photograph or
drawing, but you must explain some
important points in your report:
Writing
• a description of the object
• what it was used for
• how it was used
• when it was invented
The abacus was originally of wood. It is
a rectangular shape with beads strung on
it. The shape is unevenly divided so that
there are more beads in one part than the
other.
To use an abacus you need to take
lessons. The smaller part with fewer
Beads represents the higher numbers
and the larger part with more beads
represents the smaller numbers. By
manipulating these beads you can do a
series of different calculations.
An abacus can be used to add figures
quickly or do a series of complicated
Mathematical problems. People who
are skilled with it can work as fast as a
person using a modern calculator.
The abacus was in general use from
earliest times in China. It is not known
whether one person or a group of
people invented it.
But its value for computation is
invaluable. It is one of the few Chinese
inventions that was not adopted by the
West.
