In the lessons

In history lessons the ancient Romans built famous stone aqueducts with tall arches to bring fresh water to their cities, such as the Pont du Gard in France. In the UK, canal aqueducts like Pontcysyllte in Wales let boats cross valleys. In science they show water flowing gently downhill by gravity. Phrases: Roman aqueduct, canal aqueduct.

Note

Plural aqueducts. Spelling trap: aquEduct, not «aquaduct». «Aqua» means water, «duct» means a pipe or channel. Use «an aqueduct».
