    2021年考研英語閱讀限時練習題(3)

    考研英語是研究生考試科目中的一大難題,而考研英語閱讀又是考研英語比較難的一部分,所以從備考初期,背誦單詞之余,就要開始考研英語閱讀題目的練習,中公考研小編分享“2021考研英語閱讀限時練習題(3)”,希望能給備戰2020考研考生提供幫助。

      Antarctica has actually become a kind of space station – a unique observation post for detecting important changes in the world‘s environment. Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere, Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world.

      Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor, where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States, Switzerland, and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet – a concern they believe the world at large should share.

      The Transantarctic Mountain, some of them more than 14,000 feet high, divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain, the half of the continent south of the Americas is also covered by an ice sheet, but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared, the western part of the continent would be reduced to a sparse cluster of island.

      While ice and snow are obviously central to many environmental experiments, others focus on the mysterious “dry valley” of Antarctica, valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria Land, these valleys once held enormous glaciers that descended 9,000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone, perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roars down from the polar plateau to the sea. Left bare are spectacular gorges, rippled fields of sand dunes, clusters of boulders sculptured into fantastic shapes by 100-mile-an-hour winds, and an aura of extraterrestrial desolation.

      Despite the unearthly aspect of the dry valleys, some scientists believe they may carry a message of hope of the verdant parts of the earth. Some scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.

      1. What is the best title for this passage?

      [A] Antarctica and environmental Problems.

      [B] Antarctica: Earth‘s Early-Warning station.

      [C] Antarctica: a Unique Observation Post.

      [D] Antarctica: a Mysterious Place.

      2. What would the result be if the West Antarctic Ice Sheet disappeared?

      [A] The western part of the continent would be disappeared.

      [B] The western part of the continent would be reduced.

      [C] The western part of the continent would become scattered Islands.

      [D] The western part of the continent would be reduced to a cluster of Islands.

      3. Why are the Dry Valleys left bare?

      [A] Vicious wind blasts the snow away.

      [B] It rarely snows.

      [C] Because of the global warming trend and fierce wind.

      [D] Sand dunes.

      4. Which of the following is true?

      [A] The “Dry Valleys” have nothing left inside.

      [B] The “Dry Valleys” never held glaciers.

      [C] The “Dry Valleys” may carry a message of hope for the verdant.

      [D] The “Dry Valleys” are useless to scientists.

    Vocabulary

      1. distant-early-warning sensor 遠距離早期報警傳感器

      難句譯注

      1. Growing numbers of scientists therefore see Antarctica as a distant-early waning sensor, where potentially dangerous global trends may be spotted before they show up to the north.

      【結構簡析】see … as 把……看作。Where定從修飾Antarctic.

      【參考譯文】因此,越來越多的科學家把南極洲視為一個遠距離早期報警敏感器,在那里地球許多潛在的危險動向早在它們出現于北方以前就能發現。

      2. The part of the continent to the “east” of the mountain

      東指的使印度正南的這一部分?;蛏揭苿拥哪遣糠种?。

      3. an aura of extraterrestrial desolation

      應譯為:與地球格格不入的一種荒涼隔絕的氣氛?;蚺c世隔絕的一種荒涼氣氛。

      寫作方法與文章大意

      這是一篇有關南極洲科研考察的重要性的科普文章。采用因果,點面結合寫法。首先提出:由于南極洲遠離污染,又不同于其它任何地方,普遍存在著復雜的地質和生態環境,所以這塊地方就可能得到更敏銳又易解釋的科學測量結果。它成了監察世界環境變化的觀察哨和空間站,后面幾段就寫了進行考察的方面和結果。

      答案詳解

      1. A 南極洲和環境問題。B. 南極洲:地球最早的報警戰。C.南極洲:獨一無二的觀察哨。D. 南極洲:神秘的地方。三項都是總內容眾的組成部分。

      2. D 大陸西部成為一群島嶼。第三段“橫斷南極的山脈,有的高達一萬四千多英尺,把這大陸分成情況各異的兩個地區。山脈以東的大陸部分是由差不多兩英里厚的冰層覆蓋的高原;山脈以西,即美洲以南的半個大陸也為冰層所覆蓋??墒?,這里冰層覆蓋在大大低于海平面的巖石。如果西南極洲冰層消失,那這大陸西部將成為稀疏的島群。”A. 大陸西部將小時。B. 大陸西部縮小。 D. 大陸西部將成為分散的島嶼。

      3. C 因為地球變暖和狂風勁吹。在第四段:“……這些干谷甚至在寒冬季節也很少有冰雪。它們插在南維多利亞陸地的山脈中,一度曾有從極地高原到羅斯海的深度為9000英尺的冰河?,F在冰河已不存在,很可能是冰期之后一萬年間地球變暖的結果。即使落入干谷的雪也被從極地高原咆哮入海的邪惡狂風吹散了。留下來的是裸露的壯觀的峽谷,沙丘起伏的原野,被時速一百英里的大風雕刻成奇形怪狀的大礫石,形成與世隔絕的荒涼景象。”A. 邪惡的狂風吹走了雪。B. 它很少下雪。D.沙丘。這三項只是干谷現象的一部分。

      4. C 他們可能為地球上綠色地區帶來了希望的信息。答案是第五段第一句“盡管干谷具有神秘的一面,科學家卻相信他們可能為地球上蔥綠的地方帶來了希望的信息。”A.干谷內什么都沒有留下。B. 干谷內從沒有冰河。D. 按照科學家的看法,干谷毫無用處。
