The Ancient Road Building
A quick review of ancient history since men began keeping records of their
achievements would show that all the great empire (帝国) builders were also road
builders. They knew well that good roads were necessary for keeping the extended
empire together. The first of the great empire road builders were
the Persians (波斯人). Between 500 and 400 B. C. all the parts of the Persian
Empire were connected by roads with the capital city. The main, or "royal", road
began near what is now Turkey(土耳其), and ended in Susa. The road had well-built
inns where travelers could rest and eat, and tax-houses like those on a modern
highway.
The people of Greece, unlike the Persians, believed
that their city-states could remain independent only if the roads between them
were not too good. Besides, the landscape(风景) full of mountains in Greece made
road building an extremely difficult job. As a result, the Greeks turned to the
sea, and instead of highways, developed sea routes that reached distant
lands.
By far the greatest of the ancient road builders were the
Romans. The Romans, like the Persians before them, recognized the importance of
land routes to keep their empire together. At the height of its power, the Roman
Empire covered about 2,000,000 square miles. It extended from Spain in the west
to the banks of the Caspian Sea(里海) in the east. And from England in the
northwest, the empire stretched south to include the coastal lands of North
Africa. By about 120 A.D. the Romans had built an extraordinary network of about
50,000 miles of roads. The roads were originally built for military traffic
moving from one part of the empire to another, but during periods of peace these
same roads were busy with traders and travelers.
You can still
travel over Roman roads in many parts of Europe today. The Roman engineers knew
how to build things that would last and last.The Greeks were not interested in building roads because ______.
A．they didn’t want the city-states to be dependent on one another
B．they thought the roads between the cities were not good enough
C．they liked the natural landscape full of mountains
