[单项选择]They are "financial weapons of mass destruction," to quote the famous investor Warren Buffett as he surveyed the morning-after destruction of the sub-prime mortgage lending crisis. The continuing destruction can now be called a credit crisis—a significant escalation because credit has been the fuel powering the American economy for the past half dozen years. A whole galaxy of credit instruments has now been downgraded to the tune of hundreds of billions of dollars of paper losses. Another immediate effect has been a collapse in cash-out borrowing from home equity from about $700 billion in 2005 to $100 billion to date. At the same time, tighter lending and mortgage standards have contributed to a dramatic decline in residential construction from a high of over 2 million units to about 800,000 predicted for next year, with a related decline in employment. A slowdown in consumer spending seems inescapable. What is now seriously in question is the capacity of our financial system to provide enough credit to support the scale of investment that has maintained our long economic expansion. Coming at a time of soaring oil prices, we may have a simultaneous decline in consumer spending, residential investment, and business investment. The economy was strong in the third quarter but clearly dropping off by the end. We may be at the finish of not just the long-term borrowing bubble but the long-term spending bubble. The Federal Reserve must get ahead of the curve. Its priority must be to maintain the viability of the credit system and the flow of credit; our postmodern economy is dependent on an ongoing flow of credit. The problem for the Fed is that monetary policy may be no match for the deep structural contradictions that plague the financial system. We are dealing here with a whole new set of credit instruments that are little understood and therefore extremely difficult to price. The economy is clearly transitioning to much slower growth, sharply tighter lending standards, a declining housing market, and pressure on consumer spending. People and companies are trying to cope with the debt accumulated during several years of wasteful lending and spending. The real danger from a credit crisis is that everyone, from banks to corporations to households, may economize simultaneously. The collapse of values and the risks of the credit squeeze are the worst since the Great Depression. We are going to put the economy"s resilience to a severe test.The tighter lending and mortgage standards will probably result in
A. jump of employment rate.
B. more spending on necessities.
C. flexible cash-out borrowing.
D. a decrease of units to be built.

[简答题]美国兰德公司被誉为世界智囊团的开创者，是美国规模最大的决策咨询研究机构之一。 在研究苏联公开发表的空间技术文献后，于1946年就写报告给政府，预言苏联将于 1957年发射人造地球卫星，提出政府当年的战略措施应是加速研制人造卫星。但是，美国政府首脑对此不屑一顾。结果1957年10月4日苏联人造卫星真的上天了，大出美国政府意外。查对五角大楼的档案，竟然早已被兰德公司所预见，并且苏联人造卫星上天与兰德公司所推算的时间误差竟不超过一周。70年代中期，美国研制成功中子弹后很得意，兰德公司却指出：他们早在1958年就打报告给国防部，提出应当立即搞中子弹，政府听不进去，以致延误了十年之久。美国政府一查果然如此。 试从行政决策咨询角度分析一下这一案例。

[填空题]If there was ever a time not to postpone, that time is now. With the economy in poor shape, and many Americans pulling back on their spending for fear of what tomorrow (or even this afternoon) will bring, now is not the time to assume that the cost of some of your entertainment and communication expenses are set in stone. I found that out the hard way recently when I wondered if I could cut my expenses. Off in the corner of my desk sat a fax machine. Once humming with activity, it had been quiet for most of the last three years, except for the occasional times it spit out an ad for a fake vacation or false health care plan. I gave it little thought. That was the problem.
Ｂ. I canceled the fax rarely used, but just as rarely noticed phone line and cut my monthly expenses by $ 30. Bitten with the savings bug, I went on a rampage, thinking about every bill in sight carefully. Next on the chopping block: a third-party long-distance service once offered through Costco that was cheap
