    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)——
    練習:
    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.

     Buy energy-efficient products.—Buy new appliances or electronics of the highest energy-efficiency rating.New energy·efficient models may cost more initially,but have a lower operating _3_ over their lifetimes.The most energy-efficient models _4_ the Energy Star label.which identifies products that use 20一40 percent less energy than standard new products. According to the EPA,the typical American household can save about$400 per year in _5_ bills with products that carry the Energy Star.
    Switch to compact fluorescent bulbs.一Change the three bulbs you use _6_ in your house to compact fluorescents3.Each compact fluorescent bulb will keep half a ton of carbon dioxide out of the air over its lifetime. _7_ ,compact fluorescent bulbs last ten times as long and can save$30 per year in electricity costs.
     Set heating and cooling temperatures correctly.—Check thermostats in your home to make sure they are _8_ at a level that doesn’t waste energy.Get an electronic thermostat that will allow your furnace to heat the house to a lower temperature when you’re sleeping and retum it to a more _9_ temperature before you wake up.
