1. What three inventions will the article talk about
2. Which invention do you think is the greatest invention Why
B Before you read
The wheel, the telephone and the light bulb.
Possible answer
I think that the wheel is probably the greatest invention. Because travelling became faster and more comfortable after its invention.
The wheel
The wheel is perhaps the greatest invention in history. After its invention, travelling became faster and more comfortable.
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.
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 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 evenings as they can in the daytime. Can you imagine living without them
The wheel
The wheel is perhaps the greatest invention in history. After its invention, travelling became faster and more comfortable. 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.
