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.

□ a mobile that does videotaping

□ a mobile that is a computer

□ a mobile that wakes you up

□ a mobile that orders your food

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.
