伊瓜苏瀑布是怎样被发现的
How the Falls of Iguassu Was Discovered
In 1542，Alvar Cabeza de Vaca and his small band of soldiers guided their boats down a jungle river．It was the Iguassu，which now marks the boundary between Brazil and Argentina．Never had the explorers seen a river so beautiful．
At one point the men heard a strange rumble in the distance．It grew louder as they went on．Puzzled and afraid，they rounded a bend．Directly ahead of them the river vanished，plunging with a roar over the brink of a great chasm．
The men fought the swift current and managed to reach shore just in time to keep from being swept over the brink．Then they crept out on the wet rocks and looked into the churning caldron below．They had discovered the greatest waterfall that had ever been seen by white men－the falls of Iguassu．
