Passage Five
As my train wasn’t due to leave for another hour, I had plenty of time to spare. After buying some newspapers to read on the journey, I made my way to the luggage office to collect the heavy suitcase I had left there three days before. There were only a few people waiting, and I took out my wallet to find the receipt for my case. The receipt didn’t seem to be where I had left it. I emptied the contents of the wallet, and railway-tickets, money, scraps of paper, and photographs fell out of it; but no matter how hard I searched, the receipt was nowhere to be found.
When my turn came, I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say that he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown-looking object, no different from the many cases I could see on the shelves. The assistant then gave me a form and told me to make a list of

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)

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.
