托福口语TPO27task6题目 Listening Part:

Listen to part of a lecture in a history class.

(female professor)

So, most cities of the ancient world tended to be small, often limited to the banks of a river. They had very little means to expand. These old cities couldn’t really cross natural barriers like rivers or be located very far from water sources. But Roman cities, on the other hand, grew much larger. How did this happen?

Well, for one thing, the Romans had more advanced technology. Let’s look at a couple of Roman developments that allowed its cities to expand.

One development that’ll allow Roman cities to grow was their advanced building materials. The Romans developed a special kind o f concrete, a building material that would harden under water. And this concrete made new kinds of structures possible. Take their bridges for example. Because of this special concrete, they could build better bridges, bridges that could go across wide rivers, bridges that were big enough to transport equipment and materials with wagons and carts. So with these strong bridges, Roman cities could grow on both sides of the river, creating larger cities than would have been possible otherwise.

Another development that helped Roman cities expand was an improved way to move fresh clean water. People need access to fresh water and the Romans created an especially effective way to bring it to them. They built structures called aqueducts. Now, aqueducts are series of open channels, waterways that stretch from water sources high in the mountains to cities. They were carefully planned and built so the steady drop in altitude provides the steady flow of water to cities. These aqueducts could move tremendous amount of water over great distances and even bring fresh water to places far from rivers. Because of this, people could have clean water for drinking and bathing without being located near a river. So cities were able to grow larger in new locations.

There are two developments that allowed Roman cities to expand. The first development was that they had an advanced building material, which is concrete that hardens under water. So the Romans could build bridges that cross wide rivers, and transport wagons and cars. Therefore cities were able to grow on both sides of the river, which created bigger cities. The second development is an effective way to move clean water. They could build Aqueduct, a channel, to create asteady flow of water. So this structure could move water over a great distance.So people could have clean water without needing to be located near the river.Therefore, the cities could grow much bigger.
