Transportation means the way to go out. It has greatly changed with the development of society.
Walking was the main way until humans used animals to carry things. More than 5, 000 years ago people made the wheel successfully. This made it possible for animals to pull carts. People can travel faster. They also traveled by water, at first with simple wooden boat.
The steam engine（蒸汽机） was invented in the 1700s. It was an important thing in transportation history and it led the transportation into the modern times. Steam﹣powered boats and ships could easily travel without wind. On land, inventors used it to drive trains. This made railroads develop fast. The late 1800s saw the first successful bicycles and cars. This made quick and easy transportation possible to more people than ever before. People who bought cars needed more and better roads.
In 1903 Wilbur and Orville Wright flew the world's first plane. The invention of the jet engine in the1940s made air travel the fastest transportation in history.
The development of transportation has brought problems, however. Traffic jams, accidents and air pollution are becoming more and more serious. Choosing a green way to travel may be a thing we can do for the earth. Let's do it!
