问题 共用题干The World's Longest Bridge

Rumor has it that a legendary six-headed monster lurks in the deep waters of the Tyrrhenian Sea between Italy and the island of Sicily._______(46)When completed in 2010,the world's longest bridge will weigh nearly 300,000 tons一equivalent to the iceberg that sank the Titanic一and stretch 5 kilometers long."That's nearly 50 percent longer than any other bridge ever built."says structural engineer Shane Rixon.
_______(47)They're suspension bridges,massive structures built to span vast water channels or gorges.A suspension bridge needs just two towers to shoulder the structure's mammoth weight, thanks to hefty supporting cables slung between the towers and anchored firmly in deep pools of cement at each end of the bridge.The Messina Strait Bridge will have two 54,100-ton towers,which will support most of the bridge's load.The beefy cables of the bridge,each 1.2 meter in diameter, will hold up the longest and widest bridge deck ever built.
When construction begins on the Messina Strait Bridge in 2005,the first job will be to erect two 370 meter-tall steel towers._______(48)Getting these cables up will be something. It's not just their length一totally 5.3 kilometers一but their weight._______(49)
After lowering vertical"suspender"cables from the main cables,builders will erect a 60- meter一wide 54,630一ton steel roadway,or deck一wide enough to accommodate 12 lanes of traffic.The deck's weight will pull down on the cables with a force of 70,500 tons.In return,the cables yank up against their firmly rooted anchors with a force of 139,000 tons一equivalent to the weight of about 100,000 cars. Those anchors are essential._______(50)_______（46）A:Some environmentalists are against the project on biological grounds.B:What do the world's longest bridges have in common?C: If true ,one day you might spy the beast while zipping（呼啸而过）across the Messina Strait Bridge.D:They're what will keep the bridge from going anywhere.E:The second job will be to pull two sets of steel cables across the strait,each set being a bundle of 44,352 individual steel wires.F: They will tip up the scales at 166,500 tons一more than half the bridge's total mass.
选项 _______（46）
A:Some environmentalists are against the project on biological grounds.
B:What do the world's longest bridges have in common?
C: If true ,one day you might spy the beast while zipping（呼啸而过）across the Messina Strait Bridge.
D:They're what will keep the bridge from going anywhere.
E:The second job will be to pull two sets of steel cables across the strait,each set being a bundle of 44,352 individual steel wires.
F: They will tip up the scales at 166,500 tons一more than half the bridge's total mass.
答案 C
解析 本空前文提到：传说，在意大利和西西里岛间的第勒尼安海的深处，潜伏着一头神奇的六头怪兽。选项C中有一个关键词beast，与第一句的monster相呼应。由此可以判断出与之匹配的选项是C：如果这是真的，有一天你可能在飞驶过墨西拿海峡桥时窥视到这头怪兽。所以选项C是正确答案。
本空前文提到：这座桥桥长约5 000米，桥的结构工程师雪恩?里克森说：“它比有史以来最长的桥还长出约50%。”而后文的话题有所转移：它们都是吊桥，有着巨大的构架，横跨航道或峡谷间的巨大水域。这说明本空的内容应该起到一个很好的衔接上下文的作用，尤其要包含将本文主要讲的桥和其他桥进行比较的内容，由此可以判断出与之匹配的选项是B：那么，世界上最长的这些桥之间有什么共同点呢？ 所以选项B是正确答案。
本空前文提到：墨西拿海峡桥的建造开始于2005年，那时要做的第一项工作是竖立起两座370米高的铁塔。本空后文又提到：把这些钢缆举起来很不容易。该空后所提的这些钢缆应该出现在所填句中并且顺承上文。由此可以判断出与之匹配的选项是E: 第二项工作将是在海峡两端拉起两套钢索，每一套绳索由44 352根单独的钢缆组成。所以选项E是正确答案。
本空前文提到：这不仅仅体现在钢缆很长（共有5 300米），而且也体现在它们的重量。空前一句的重点落在重量这个概念上，所以下一句应该围绕桥的重量展开说明。由此可以判断出与之匹配的选项是F：它们将重达166 500吨，这个重量已超过了桥总重量的一半。所以选项F是正确答案。
在做本题前，挑出剩下的两个选项A和D。本空前文提到：这些固定物是很必要的。由于选项A将话题转向环保主义者，而文章结尾句一般不提出新话题，加之通过内容判断，选项D中的they应该指的是上一句的固定物，上一句说的是其重要性，下一句说其功能，是对上一句观点的支持。所以选项D是正确答案。
