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 2,500milelong rocky coastline of Marine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited, but many are home to thriving munities. 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 home for the wealthy. Recently though, Bar Harbor has bee a rapidly growing arts munity 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 (溫帶) and subArctic zones, the islands supports the plants and animals of both zones as well as beach, inland, and alpine (高山的) (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. 　　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 of the islands left behind by the glacier 　　C The wealthy residents of Mt. Desert Island selfishly kept it to themselves. 　　D The term es 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. 　　第6部分：完形填空（第5165題，每題1分，共15分） 　　下面的短文有15處空白，請根據(jù)短文內(nèi)容為每處空白確定1個最佳選項(xiàng)。 　　2 、A又如: His English has been considerably improved. 他的英語大有起色。 　　3 、C 　　 D 　　5 、C 　　 D和它同義的詞常用的有 bear, endure和 stand。 　　9 、Chail 這個動詞有熱情贊揚(yáng)、歡呼認(rèn)可等意思，如: They hailed the young pianist for his marvelous performance. 　　他們對那位年輕鋼琴家的出色演奏大家贊揚(yáng)。注意本句中的謂語動詞The young man is being hailed. . . 是被動式，現(xiàn)在進(jìn)行時。不過在本句里，scared 并非懼怕的意思，而更接近于擔(dān)心的意思，故和 afraid 相當(dāng)。 grasp 這個動詞是抓住的意思，可用于具體的事物，如: grasp the rope/my hand 抓住繩索/抓住我的手，也可以用于抽象的概念，如：grasp the main idea/ his meaning 抓住要點(diǎn)/理解他的意思。 　　13 、Aassert 是個比較正式的詞，表示聲言、提出主張等，故和表示自己立場的 maintain 同義。 　　14 、C Sharp decline 則是急劇下降。 find fault with somethin
