Passage 1
The collapse of the Berlin Wall and the disintegration of the USSR ushered in the richest boom in capital flows to emerging markets(新兴市场) thet drove spectacular global economic growth. But that era of challenges and opportunities has now ended. The Asia economies have fallen into dectine. Their financial and economic crises have become global crisis affecting all the emerging markets. The great multinational firms that had been the big economnic winners have seen their profit growth slip. Investors, who once had a great tolerance for risk, now are wary. Whatever tolerance that drove global capital flows in the past has now diminished to the point where asset holders have bailed out of stock markets around the world--not just the markets in the once developing world, but from US and European markets as well. Money has fled mostly into sovereign debt instruments, primarily US securities, or is just waiting under the mattress.
For one thing, the United States, by all accounts will continue to be the locomotive (火车头) of global economic growth. The US economy will be constrained by the collapse of so many emerging markets, just as the profits of many multinationals have been trimmed. But the downward pressure on the US is unlikely to force a recession. Americans have a great appetite to consume imported goods, especially now that states that seek to export have weakened currencies and the US has a strong dollar. This future for world trade is especially bright given that the principle trade partners of the US are its nearest neighbors and those partners are likely to continue to benefit most directly from the strength of the US economy.
44.US securities are reiatively safe for investors.
A、True
B、False
【正确答案】：A
【名师解析】:根据文章内容，美国证券被认为是相对安全的，因为文中提到了投资者对风险的容忍度下降，导致资金从全球股市撤出，转而流入主权债务工具，主要是美国证券，或者仅仅是存放在床垫下。这表明在当前全球经济不稳定的情况下，美国证券被视为一种避险资产，因此选项A "True" 是正确的。
