- Electric cars emit no exhaust while driving; rail carries many with least pollution.

§Text Passage
1The history of transport is a story of going ever faster. It began with walking and human-carried sedans, then tamed horses and camels; after the wheel came horse and ox carts. The Industrial Revolution leapt ahead: steam trains and steamships in the nineteenth century freed travel from muscle power, and in the twentieth the internal combustion engine and the aeroplane sped land, sea and air alike.
2Hong Kong's transport mirrors this evolution. The Peak Tram opened in 1888; trams began running on Hong Kong Island in 1904; the Star Ferry has crossed the harbour for over a century; the underground railway opened in 1979 and grew into today's MTR network; Chek Lap Kok airport opened in 1998; and in 2018 the high-speed rail Hong Kong section joined the national network.
3Modern transport turns green and smart. Electric vehicles replace petrol with batteries and emit no exhaust while driving, and the government promotes them with charging facilities. Rail carries the most passengers with the least pollution. Smart traffic systems use sensors and data to control lights and forecast arrivals. Autonomous driving lets computers assist or even replace the driver.
4Progress brings duties: exhaust and carbon emissions worsen air pollution and climate change, so use public transport and walk or cycle short trips; obey traffic rules and cross at the lights. The transport of the future is built by technology and good citizenship together.

3Step by step Steps
- Step 1: Line up the timeline of transportTransport keeps improving with the times: faster speeds and cleaner power. For example, ancient times relied on walking and horse carts; steam trains and ships appeared in the nineteenth century; cars and aeroplanes came in the twentieth; and today we have high-speed rail and electric cars. Lining these vehicles up in order shows the track of technological progress clearly: from muscle to steam, then to electricity and new energy.
- Step 2: Learn Hong Kong's transport milestonesHong Kong's transport has clear milestones that mark the city's growth. For example, the Peak Tram opened in 1888, trams began running on Hong Kong Island in 1904, the underground railway opened in 1979, Chek Lap Kok airport opened in 1998, and the high-speed rail Hong Kong section opened in 2018. Knowing these years and events helps us see how transport links joined up the whole territory step by step — and even the whole country.
- Step 3: Compare power sourcesDifferent vehicles use different power sources, and their effects on the environment differ too. For example, steam engines burned coal and poured out black smoke; car engines burn petrol and emit exhaust; electric cars emit none while driving, and electric rail carries great crowds of passengers with the least pollution. Comparing the strengths and weaknesses of each power source shows why society promotes electric cars and mass transport to cut air pollution.
- Step 4: Meet smart trafficSmart technology makes travel easier, and Hong Kong's transport is already very smart. For example, bus-stop screens show the arrival time of the next bus; an Octopus card opens the gate in a second; navigation apps report traffic jams at once and suggest the fastest route. Learn to use these smart apps, plan the route and check arrival times before setting out, and we save time and cut the waiting.
- Step 5: Practise green travelGreen travel cuts exhaust and protects the environment while keeping us healthy. For example, take the MTR or bus to school instead of the family car; walk or cycle trips under two kilometres, training the body and cutting carbon at once. Every choice of public transport, walking or cycling adds a small effort to reducing air pollution; on family outings, suggest taking mass transport too.
- Step 6: Be a rule-abiding road userHowever many and advanced the vehicles, safety still depends on everyone following the rules. For example, cross at zebra crossings or footbridges and watch the lights clearly; let passengers off before boarding, queue in order, and offer seats to those in need; never chase or shout inside the carriage. Following the rules protects ourselves and keeps every journey smooth and calm — the duty of every road user.
- Step 7: Imagine transport to comeThe transport of the future is taking shape in trials, bringing both excitement and new questions. For example, autonomous buses, hydrogen trains and low-altitude aircraft are being tested around the world; future travel will be faster and greener — and must be safer. While imagining future transport, we should also think: how can new technology serve everyone safely? Those questions wait for today's pupils to answer when they grow up.

5Worked example Example
Example: Kit's family plans to travel from Taikoo to the airport by private car, by MTR and Airport Express, or by taxi. Compare them on time, cost and the environment, and give a recommendation.
- Private car: about forty-five to sixty minutes depending on traffic; tunnel and parking fees; the highest carbon per person.
- MTR and Airport Express: a steady journey of about an hour; moderate cost; electric trains make it the greenest.
- Taxi: about forty-five to sixty minutes; higher cost; more emissions than rail.
- Recommendation: for a small group the Airport Express is steady and green; consider taxi or car only with heavy luggage — and share rides where possible.
- Answer: For steadiness and the environment, the MTR and Airport Express route wins; weighing time, cost and carbon before choosing is the wise traveller's way.
