Mt. Desert Island
The coast of the State of Maine is one of the most irregular in the world. A
straight line running from the southernmost coastal city to the northernmost
coastal city would measure about 225 miles. If you followed the coastline
between these points, you would travel more than ten times as far. This
irregularity is the result of what is called a drowned coastline __________
(46). At that time, the whole area that is now Maine was part of a mountain
range that towered above the sea. As the glacier (冰川) descended, however, it
expended enormous force on those mountains, and they sank into the sea.
As the mountains sank, ocean water charged over the lowest parts of the
remaining !and,forming a series of twisting inlets and lagoons (咸水湖. The highest
parts of the former mountain range, nearest the shore, remained as islands.

rapidly growing arts community as well. But, the best part of the island is the
unspoiled forest land known as Acadia National Park.
Because the island sits on the boundary line between the temperate (温带) and
sub-Arctic zones,the island supports the plants and animals of both zones as
well as beach, inland, and alpine ( 高山的) plants. __________ (49) The
establishment of Acadia National Park in 1916 means that this natural reserve
will be perpetually available to all people, not just the wealthy. Visitors to
Acadia may receive nature instruction from the park naturalists as well as enjoy
camping, cycling, and boating. Or they may choose to spend time at the
archeological museum, learning about the Stone Age inhabitants of the
