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．——(1)——When completed in 2010，the world’s longest bridge will weigh nearly 300，000 tons—equivalent to the iceberg that sank the Titanic—and stretch 5 kilometers long．“That’s nearly 50 percent longer than any other bridge ever built，”says structural engineer Shane Rixon．
——(2) ——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．——(3)——Getting these cables up will be something．It’s not just their length—totally 5.3 kilometers—but their weight．  ——(4)——
After lowering vertical“suspender”cables from the main cables．builders will erect a 60 meter-wide 54．630-ton steel roadway, or deck——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 1 39。000 tons—equivalent to the weight of about 100，000 cars．Those anchors are essential．——(5)——
 
练习：
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—more than half the bridge’s total mass．

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. __1__ When completed in 2010, the world’s longest bridge will weigh nearly 300,000 tons –equivalent to the iceberg that sank the Titanic.
1. C。分析：思路特点：注意空格前后句中的词语使用特点：前句中发现了a legendary six-headed monster（与C中的the beast呼应），而C中的the Messina Strait （Bridge）也在空格前句中有呼应的内容：the deep waters of the Tyrrhenian Sea between Italy and the island of Sicily，有两个线索可以表明C是答案，因此判断C是答案。
 
A   Some environmentalists are against the project on biological grounds.
B   What do the world’s longest bridges have in common?
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 individuals steel wires.
F   They will tip up（使倾斜） the scales at 166, 500 tons – more than half the bridge’s total mass.
 
 

A   Some environmentalists are against the project on biological grounds.
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 individuals steel wires.
F   They will tip up（使倾斜） the scales at 166, 500 tons – more than half the bridge’s total mass.
 
When construction begins on the Messina Strait Bridge in 2005, the first job will be to erect two 370 meter-tall steel towers. __3__. Getting these cables up will be something.
3. E。 分析：思路特点：注意空格后句中的词语使用特点：空格前面中出现了the first job(与E中the second job呼应)，而空格后句中的 theses cables 在E中也有呼应内容： steel cable，因此判断E是答案。
 
A   Some environmentalists are against the project on biological grounds.
D   They’re what will keep the bridge from going anywhere.
F   They will tip up（使倾斜） the scales at 166, 500 tons – more than half the bridge’s total mass.
 
It is not just their length –totally 5.3 kilometers – but their weight. __4__.
4. F. 分析：思路特点：注意空格后句中的词语使用特点：空格前出现了their length， their weight，因此判断their可能指“桥”，剩下的选项中：F中提到了有关重量的数据166, 500 tons，因此F是答案。
 
A   Some environmentalists are against the project on biological grounds.
D   They’re what will keep the bridge from going anywhere.
 
Those anchors are essential. __5__.
5. D。分析：思路特点：注意空格后句中的词语使用特点：空格前面出现了Those anchors（这些桥桩），而D中的句意（它们是防止桥移动的东西）正是解释了桥桩的作用
