23、to be mobbed by luxury property developers trying to hawk them 1 million condos (a handful of new buildings in the city are marketed mainly to rich Irish). Manhattan, like other posh areas of America, is now full of homes meant for foreigners. One in five American real estate agents sold a house to
24、an expatriate last year. The reason is obvious: From Rio to Riyad, dollar assets are a bargain.The shift, which has been coming for several years now and will be much discussed at the World Economic Forum in Davos this week, is seismic. Since the end of World War , the dollars unique role as the int
25、ernational currency has afforded Americans a tremendously privileged place in the world. We filled most of the seats on transatlantic flights, and bought second homes abroad. Our currency was prized by central banks. Countries pegged their monies to the dollar. Commodities were priced in dollars. Th
26、e strength of the greenback, and of the economy, underpinned US global hegemony in politics and culture. Big American banks like Citibank used to fund Third World governments-now those governments are buying Citibank on the cheap.Clearly, times have changed. The dollar-along with Americas economic p
27、lace in the world- has been on a well-documented downward spiral since 2002. Back then, a euro was worth 86 cents. Today, it buys 1.46. Of course, the euros relative youth makes talk of “historic lows“ easy to dismiss. More telling is that the US Dollar Index, a futures contract reflecting the dolla
28、rs strength against six other major trading currencies, hit the lowest mark in its 35-year history just before Christmas.The shift will of course have major ramifications. Countries are beginning to de-link their currencies from the dollar, as inflationary pressures make it difficult to implement ef
29、fective local monetary policy. Large global creditors like the Chinese have announced their intent to scale back on dollar reserves. European Central Bank head Jean-Claude Trichet is grousing about “brutal“ movements in the dollar-euro exchange rate slashing profits at Europes biggest firms. Just la
30、st week, Airbus CEO Tom Enders warned that a weak dollar threatened the long-term existence of the Continental aerospace giant. Japans new Prime Minister Yasuo Fukada worries that the plunging greenback will bring back deflation. And OPEC is studying the possibility of pricing oil in euros- a move t
31、hat would not only amount to a vote of no confidence from some of Americas largest creditors, but would also make energy much more expensive for the United States, compounding the economic troubles which led to a weak dollar in the first place.Venuezuelan president and Bush-basher Hugo Chavez recent
32、ly gloated, “The empire of the dollar is crumbling.“ But thats not quite right. The majority of the worlds financial assets and central bank reserves are still held in dollars. It will take years for the euro to become a real rival; the renminbi will rise over decades. Still, whats clear is that we
33、have entered a new era. The United States can no longer rule the world on credit. A rebalancing has begun.（分数：5.00）(1).Which is true of Manhattan luxury homes?（分数：1.00）A.20% of them were sold to foreigners last year.B.Many of them were built for foreign buyers.C.They were mainly targeted at buyers f

37、irls best friend“ in rings, tiaras and the Pink Panther films. Yet the aesthetic uses for these sparklers are in the minority. Today, many diamonds are made synthetically for a vast range of uses, from surgeons scalpels to super-fast microchips.Labs produce 180 tonnes of diamond each year-almost nin
38、e times as much as comes out of the ground. And its strength, clarity and chemical resistance could make it the engineering material of the 21st century. Already, there are diamond heat sinks for tiny integrated circuits, diamond coatings on joint replacements and diamond windows on space probes. So
39、on, a diamond coating could protect your car gearbox, and super-strong diamond threads be used to reinforce ultra-light aircraft.Diamond is far more than just a pretty rock. It has an impressive list of properties. As the hardest material known to science, it is resistant to attack by strong acids a
40、nd alkalis and is a superb conductor of heat. This all means that there are many uses for diamond apart from the purely decorative. Because it dissipates heat so well-much better than silicon, engineers want to build microchips on layers of diamond. They could then squeeze yet more electronic compon
41、ents into smaller areas without the circuit overheating, to produce a new generation of super-fast computers.The key to diamonds extraordinary properties is its structure. Carbon can form four strong bonds with other molecules, which is why it forms the basis of so many organic compounds and is the
42、building block of life. When four carbon atoms are linked together in a regular lattice, the result is a diamond crystal. Another form of carbon is the graphite in pencils.Companies such as De Beers and General Electric have been making synthetic diamonds since the early 1950s. Almost any substance
43、rich in carbon can be converted into diamond. General Electric chemist Robert Wentorf once made diamonds from peanut butter.A newer process, chemical vapour deposition(CVD), is used to produce ultra-hard diamond coatings. CVD used high temperatures but low pressures to coat a substance with carbon v
44、apour, as a layer of small diamond crystals. These crystals will eventually join together and can be used to create huge gems. Diamonds such as this are usually sliced up to produce long scalpels or other tools.CVD has scientists excited. “For the first time, we have all the superlative properties o
45、f diamond in a form thats useful for engineering applications.“ Says May, who uses CVD to create diamond threads by coating tungsten wire. So it seems that diamonds are not just a girls best friend, but an engineers too.（分数：5.00）(1).Which of the following best explains what makes diamond a good engi
