Unit 2 Numbers
The king and the rice
A long time ago, there was a king in India. The king’s favourite game was chess.
One day, a wise old man came to the palace and the king challenged him to a game. The king promised the old man, “ You can have any prize if you win the game.”
The old man said, “If I win the game, I’d like one grain of rice for the first square of the chessboard, two for the second, four for the third, and then double the amount for each of the rest of the squares.”
“Is that all?” asked the king. “Wouldn’t you like gold or silver instead?”
“No, just rice,” replied the old man.
The king and the old man played the game for a long time. Finally, the old man won. So the king ordered his men to collect a bag of rice. He put one grain on the first square, two on the second, and so on. The king quickly realized the problem --- even with all the rice in the country, he would still not have enough rice to put on all the squares!

Read the online article and then plete the flow chart about the development ofcounting methods.
Counting before numbers
Before the invention of written numbers, people used many different ways to count things.
At first, people used their fingers, and eveii their toes. However,they could only count small numbers in this way.
After that, they began to make small marks on sticks and bones. This helped them count bigger numbers. They used them to count things like the days of the month, the amount of food and the number of animals they had.
Then people began to use tokens made from clay or small stones. This helped them count even bigger numbers. They often put the tokens on pieces of string so that they could carry them around easily. This developed into tools like the abacus.
Finally, people began to develop systems of written marks to show different numbers, and this led to the Hindu-Arabic system (0-9). We are still using this system today.

Unit 3 puters
puter facts
Smaller and better
In the 1940s, the first puters were bigger than cars. Now puters are being smaller and better.Some puters are tiny. You may be unaware of them. There is probably one inside your TV or washing machine. You depend on puters more than you realize.
What can we do with puters?
We can use puters to calculate. They can calculate at a faster speed than we can and almost never give wrong answers. We can also type and draw things with them. In addition, puters can do important jobs like operating railways and flying planes and spaceships.
Is a puter cleverer than me?
The answer is “No”. Your brain can produce new ideas but puters cannot. However, one day puters may be able to a better job than human beings. For example, they may be better than doctors at doing their job.
What will happen to us if puters can do all our jobs? Will we have nothing to do? puters may change our lives, but will they make them better?

puter game problems
Good afternoon, parents and teachers. Thank you for attending this meeting.
Last weekend, one of our students went to hospital. The student played puter games on the Internet all day Saturday without stopping to drink, eat or sleep. Finally, he became very ill.
Some students play puter games for too long. This is a serious problem. In the past, students used to play outside more often, but now they spend more time in front of puters. This is bad for their health.
Tomorrow we'll have some experts here to talk to the students about the bad effects of playing puter games. They'll also give some advice on how to use puters for studying.
I hope we can all work together to stop students from spending too much time playing puter games. Thank you for your time.

Unit 4 Inventions-Great inventions
Great inventions change the world. They help people live a better life. The following are three of the most important inventions in history.
The wheel
The wheel is perhaps the greatest invention in history. After its invention, travelling became faster and more fortable. A few thousand years ago, people started to use wheels on carriages. In the early 19th century, the first trains began to carry passengers. At the start of the 20th century, cars became popular. Without the wheel, we would not have these inventions.
The telephone
Alexander Graham Bell invented one of the first practical telephones in 1876. Since then, people have been able to speak to each other over long distances. Today millions of people across the world own mobile phones. They allow people to keep in touch with each other anytime, anywhere.
The light bulb
Thomas Edison developed the first practical light bulb in 1879. Before the invention of the light bulb, people had to use oil lamps, gas lamps or candles to see at night. With light bulbs, people can do as many things in the evening as they can in the daytime. Can you imagine living without them?
