Cloze (10 points) choices marked A,B,C,and D.Choose the best answer for each blank and mark your answer on the Answer Sheet. Millions of years ago, a volcano (火山) builtamountain on the floor of the Atlantic. In eruption after eruption, it lifted upagreat pile of volcanic rock, until it had accumulated a massahundred miles across at its base, reaching upward toward the surface of the sea, emerging as an island of about two hundred square miles. Thousands of years passed, and thousands of thousands. Eventually the waves of the Atlantic reduced it toasmall fragment above water. This fragment we know as Bermuda. With variations, the life story of Bermuda has been repeated by almost every one of the islands that interrupt the watery expanses of the oceans far from land. These isolated islands in the sea are fundamentally different from the continents. The major land masses and the ocean basins today are much as they have been throughout the greater part of geologic time. But islands are created today, destroyed tomorrow. They are the result of the violent, explosive, earth-shaking eruptions of submarine volcanoes, working perhaps for millions of years to achieve their end. Islands have always attracted much attention. Our imaginations can follow its shapes down through darkening waters to where it rests on the sea floor. We wonder why and how it rose here in the midst of the ocean.

译文 / 解析

本文主要描述了由海底火山堆积而成的岛屿的形成过程。

数百万年前,大西洋海底的一座火山建造出了一座山。在一次又一次的喷发中,它堆积了大量的火山岩,直到在海底形成一个横跨百英里的巨大火山岩体,这个火山岩体向上延伸至海面,最终形成一座约两百平方英里的小岛。成千上万年过去了,最终,大西洋的海浪逐渐将这座岛屿侵蚀,最终只留下一小部分露出水面。这一部分就是我们所熟知的百幕大群岛。尽管各有不同,几乎每一座远离陆地、点缀在广阔海洋上的岛屿都重复着类似百慕大的生命故事。这些孤悬于海上的岛屿与大陆截然不同。今天的主要陆地板块和海洋盆地与其在地质时期的大部分时间基本相同。但是,岛屿却可能在今天形成,到明天就被毁灭。它们是海底火山剧烈、爆炸性、震撼性的喷发所产生的结果,可能需要数百万年的时间才能达到它们的终结。岛屿一直备受关注。我们的想象力可以从它的外形穿过逐渐幽暗的海水,直到它海床的根部。我们想知道它为什么以及如何从海洋中央崛起。

1. washed
2. lifted
3. pushed
4. moved
答案 B

本题考査的是上下文语意衔接。wash"洗"; lift "提起,举起,提高", 通常表示从低往高(从下往上)提起,提升:push"推,移动",一般是在一个平面上推动、移动move"移动,(使)改变位置"，这里描述的是火山爆发时将火山岩从海底推上来堆积形成岛屿的过程,只有lift 符合语境。
1. upward
2. downward
3. forward
4. backward
答案 A

本题考査的是上下文语意衔接。后文提到"reaching...toward the
1. Suddenly
2. Admittedly
3. Practically
4. Eventually
答案 D

本题考查的是上下文语意衔接。空格前一句提到"Thousands of years passed...", 说明经过很长的时间后,最终发生了某个结果。根据句意和选项的意思, 只有eventually"最终"符合语境。
1. by
2. like
3. as
4. of
答案 C

本题考查的是固定搭配。本空格处是固定搭配"know as...",表示"作为……认识"。
1. rocks
2. islands
3. lands
4. seas
答案 B

本题考查的是上下文语意衔接。文章第一段提到了海洋中的一个小岛,经过海浪的侵蚀只留下了一小块,也就是百慕大,空格所在句说:类似百慕大的生命故事在被……不断重复。由于百慕大是来源于岛屿,所以这里应该是说每个岛屿都在重复百慕大形成的过程。四个选项中只有island 符合。
1. forgotten
2. man-made
3. lost
4. isolated
答案 D

本题考査的是上下文语意衔接。前一句中提到这些岛屿远离大陆, 点缀在广阔海洋上,本句中islands也有后置定语in the sea, 所以修饰岛屿的最恰当的词就是isolated"与世隔绝的,孤寂的"。
1. today
2. yesterday
3. tomorrow
4. once
答案 A

本题考査的是时间状语的选择。空格后"are much as they have been throughout the greater part of geologic time"指的是和地质时代大部分时间一样, 所以应该是拿现在和过去比,只有today 符合今昔对比的语境。
1. cause
2. problem
3. result
4. change
答案 C

本题考查的是上下文语意衔接。空格前的主语ey 指代前面提到的岛屿海底火山剧烈、爆炸性、震撼性的喷发"是形成岛屿的原因,而岛屿自然就是这一活动的"结果"。
1. attacked
2. arrested
3. attached
4. attracted
答案 D

本题考查的是固定搭配。句中提到"岛屿总是……很多关注" "attracted"用在此处合适,与空格后的attention 构成固定搭配,表示"吸引注意",
1. what
2. where
3. how
4. when
答案 B

本题考查的是宾语从句连词的选择。介词to 后面是一个句子,这里需要一个连词引导宾语从句,因为从句不缺成分,所需要一个连接副词。A 是连接代词,要在句中作成分,故排除。而本句中说的是想象力是从外形到岛屿根基所在的海底,所以需要补全一个地点，应该用连接副词where 来引导。
