问题 The Dead Sea, shared by Israel and Jordan, is the lowest spot on Earth. Its shoreline is a-bout 400 meters below sea level. As the world’ s saltiest large body of water, averaging a salt content 6 times higher than that of any ocean, the Dead Sea supports no life. With no outlet, the water that flows into the Dead Sea evaporates in the hot, arid air, leaving the minerals. The Jordan River is the chief source of the incoming water, but since the 1960s much of its water has been diverted for irrigation. Its length has already shrunk by more than a third, and, while the sea will never entirely disappear due to evaporation slowing down as surface area decreases and saltiness increases, the Dead Sea as we know it could become a thing of the past.

选项

答案 位于以色列和约旦边境的死海是地球上的海拔最低点。它的海岸线大约在海平面以下400米。作为世界上最咸的一个水体,死海的平均含盐量是普通海域的六倍,因此死海中没有任何生命。由于没有出口,流入死海的水只能靠炎热干旱的空气蒸发,留下矿物质。约旦河是进水的主要来源,但自从60年代以来,约旦河的水大部分被用于灌溉。它的长度已经缩短了三分之一以上。虽然死海永远不会完全消失,因为海域面积的缩小和含盐量的增加使蒸发不断减缓,但我们所了解的死海或许终究将成为历史。
