Listening text R=Reporter P=Professor Jiang R: Discovering new places and going where no one has gone before has always been the greatest adventure in human history. Professor Jiang, what made exploring so exciting in the past?

P: Classical examples of exploring the world are the great discoveries made by explorers. They were brave men such as Christopher Columbus, who sailed around the world in tiny ships crossing oceans and seas for thousands of miles in search of land. And in the nineteenth century there

were famous explorers who mapped the rivers, lakes, jungles and mountains that make up the con- tinents. R: What different did they run into? P: Well, just imagine how difficult it must have been to explore the jungle without the benefit of modern com-

munications technology and transport! It was not unusual that journeys took tow or three years. Transport con-sisted of horses or camels and several hundred or even a thousand people to carry all the equipment, food and medicine for such a long trip. There were no roads and no maps. Discoveries

weren’t published until at least a year later. Explorers found mountains, poisonous snakes, dangerous animals and terrible diseases on their way. And there were frightening stories and rumours about people who ate people, mysterious cities and hidden treasures. Compare that with modern

science where we can use telescopes and satellites to see where we are going, use cars, trucks, aeroplanes or helicopters to travel fast and mobile phones, computers and the Internet to inform each other quickly about new discoveries or call for help. R: Then where’s the challenge in modern

science? Is science still an adventure? P: It sure is. Exploring the moon, other planets, such as Mars and the rest of the universe is still a challenge. Modern techniques help us and they reduce the risks to the explorers, but the experience of discovery, of being the first to see something or visiting

a place, even though we’re only looking at it through telescopes or sending out a robot, is as exciting as the experience of the great explorers of the past.
