[不定项选择题]共用题干 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 land,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.___________(47)Marine fossils found here were 225 feet above sea level,indicating the
level of the shoreline prior to the glacier.
The 2,500-mile-long rocky coastline of Maine keeps watch over nearly two thousand islands.Many of
these islands are tiny and uninhabited,but many are home to thriving communities. Mt. Desert Island is one of the
largest,most beautiful of the Maine coast islands.Measuring 16 miles by 12 miles,Mt. Desert was essentially
formed as two distinct islands.__________(48)
For years,Mt. Desert Island,particularly its major settlement,Bar Harbor,afforded summer homes for the
wealthy.Recently though,Bar Harbor has become a 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 island.
The best view on Mt. Desert Island is from the top of Cadillac Mountain._________(50)From the
summit,you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty
created by a retreating glacier. _________(50)
A.It also lies in a major bird migration lane and is a resting spot for many birds.
B.Mt. Desert Island is one of the most famous of all the islands left behind by the glacier.
C.The wealthy residents of Mt. Desert Island selfishly kept it to themselves.
D.The term comes from the activity of the ice age.
E.This mountain rises 1,532 feet,making it the highest mountain on the Atlantic seaboard.
F.It is split almost in half by Somes Sound,a deep and narrow stretch of water,seven miles long.
