§Text Passage
1Long ago, humans walked; reaching a far place took many days. Later people tamed horses and rode them or rode horse carts, a little faster. On water, people first paddled canoes, then invented sailing ships that travelled on the wind.
2After the steam engine came steam trains and steamships, carrying many more people and goods. Then cars and aeroplanes appeared one after another: cars run on roads, planes carry people across the sky, and crossing an ocean takes only a dozen or so hours.
3Modern transport keeps improving: high-speed rail runs over three hundred kilometres an hour, and metro trains shuttle beneath cities. Hong Kong's ferries, buses and trams each have character — the double-decker tram still trundles along the streets after more than a hundred years of service.
4Better transport makes life easier, and we must be courteous passengers: queue to board, offer seats to those in need, and fasten seat belts. Maybe flying cars and greener electric vehicles are coming — let's wait and see!

3Step by step Steps
- Step 1: The earliest travelIn the earliest times, people could only walk on their own two feet to faraway places, and one trip took many days. Later, people tamed horses and rode them or rode in horse carts, and the speed got much faster at once. From walking to horse carts was the first big step in transport, making it much easier for people to visit one another. Why do people keep improving transport? Because everyone wants to travel faster, farther and more comfortably. A common mistake is thinking transport was always there; every kind of transport was invented and improved step by step by human beings.
- Step 2: Travel on waterTravel on water has been improving day by day too. Long ago, people cut down big trees to make little canoes; later the sailing ship was invented and travelled by wind, faster and farther; when steamships appeared, they could cross the great sea without wind; today's giant cargo ships carry thousands of containers across the oceans. A common mistake is thinking sailing ships and steamships are much the same; sailing ships rely on wind and steamships on engines — different power means very different speed and carrying capacity.
- Step 3: Trains evolveTrains keep getting stronger and faster. Old steam trains burned coal, puffed white smoke from the engine, and ran slowly and noisily; later came electric trains, much cleaner and quieter; today's high-speed rail runs more than three hundred kilometres an hour, fast and steady. Sitting on a high-speed train, the beautiful scenery outside the window flashes past — comfortable and amazing. A common mistake is thinking all trains are alike; trains of different eras use different power, from burning coal to electricity, and the progress is plain to see.
- Step 4: Into the skyPeople have always dreamed of flying into the blue sky like birds. In 1903, the first powered plane flew successfully; though it only travelled a short way, it made a thousand-year dream come true. Today's big airliners can carry more than three hundred passengers and fly across half the globe in a dozen or so hours, making visits to distant relatives far easier. A common mistake is thinking planes flew high and far from the start; early planes were small and unstable, and only through countless engineers' efforts did today's airliners appear.
- Step 5: Hong Kong's special transportHong Kong has some especially lovely kinds of transport. The double-decker trams began service in 1904, walking slowly along Hong Kong Island — people call them the ding ding trams; the Peak Tram climbs up Victoria Peak and has carried sightseers for over a century; the MTR travels under the ground and under the sea, carrying millions of passenger journeys every day; and the Star Ferry shuttles across the harbour. They are all good helpers in Hong Kong life. A common mistake is thinking Hong Kong has only buses and the MTR; look carefully, and the city's transport is rich and full of character.
- Step 6: Be a courteous passengerWhen riding any transport, be a rule-following, well-mannered passenger. Queue when boarding, let the people on the vehicle get off first, then get on in turn; offer your seat to elders and people in need on the bus or train; fasten your seat belt in a car or bus; and keep your voice down and never drop litter in the carriage. When everyone rides politely, every journey is safe and pleasant. A common mistake is rushing and pushing at the door; crowding at the door is dangerous — queuing is the fast and safe way aboard.

5Worked example Example
Example: from Hong Kong to Beijing, which is fastest — walking, high-speed rail or flying? About how long does each take?
- First compare the speeds: walking is about five kilometres an hour, high-speed rail over three hundred, and a plane about nine hundred.
- Walking to Beijing would take months — not practical at all.
- High-speed rail arrives in about nine hours, steady and comfortable.
- A plane takes about three and a half hours, the fastest of the three.
- Answer: Flying is fastest at about three and a half hours; high-speed rail follows at about nine hours; walking would take months and is not practical. The longer the distance, the more the fast vehicles stand out, so long journeys call for the right transport.
