　　The World's Longest Bridge

　　Rumor has it that a legendary (傳說的) 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---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.

　　__________(47) They're suspension bridges, massive structures built to span vast water channels or gorges (峽谷). A suspension bridge needs just two towers to shoulder the structure's mammoth ( 巨大的 ) weight, thanks to hefty ( 高強度的 ) 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(結實的) 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 theft length--totally 5.3 kilometers--but their weight.__________(49)

　　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 (拽) up against their firmly rooted anchors with a force of 139,000 tons---equivalent to the weight of about 100,000 cars. Those anchors are essential. __________ (50)

　　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 (呼嘯而過) 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.

　　答案及解析：

　　46.C。選項C中有一個關鍵詞beast，與第一句中的monster相呼應。所以C是答案。

　　47.B。第二段第二句的主語是they。由于表語是suspension bridges，所以they替代的一定是前面句子出現過的bridges。六個選項中，只有B含有bridges。因此填在第二段段首，使意思連貫。

　　48.E?？瞻滋幥懊娴木渥又杏衪he first iob這幾個詞。有first，必有second/then。六個選項中，只有E含有the second iob，所以E是答案。

　　49.F。空白處前面的句子說的是，把這些吊索吊高定位是有難度的，因為它們不僅很長，還很重;后面應該接著說吊索的情況，故選F。

　　50.D?？瞻滋幥懊娴木渥诱f橋樁很重要，后面接著還應該說橋樁的事情。D項解釋了橋樁的作用，故選D。
