69-71. BAD
本表格是美国历次战争的开支情况统计。
69. B。细节题。从表中可以看出美国内战和第二次世界大战的费用分别占美国年度国民生产总值的104%和103%，超出了它的年度GDP。故选B。
70. A。推测计算题。从常识中可以知道，1951年美国正处在朝鲜战争之中，而美国在朝鲜战争的花费为 $335.9 billion，占它的年度GDP的15%。据此可以计算出它1951年的 GDP 应为 $2.239 trillion。
71. D。事实确认题。D项明显错误。Mexican War 和 Spanish American War 两场战争的花费占年度的GDP比率相同，但并不等于两场战争的费用是一样的。

This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!

1._____________________
Physicians’ fees are only one reason for rising health costs in the United States. Medical research has produced many tests to diagnose, or discover, patients’ illness. Physicians usually feel obliged to order enough tests to rule out all likely causes of a patient’s symptoms. A routine laboratory bill for blood tests can easily be more than $100.
2. _____________________
Sophisticated new machines have been developed to enable physicians to scan body organs with a clarity never before possible. One technique involves the use of ultrasound – sound waves beyond the frequencies that human beings can hear – to produce images. Others use computers to capture and analyze images produced by X-rays or magnetic fields. These machines are extremely expensive: The price of a single machine can exceed one million dollars.
3._____________________
New technologies also mean new personnel. Physicians, nurses and orderlies can no longer staff a hospital alone. Hospitals now require a bewildering number of technical specialists to administer new tests and operate advanced medical equipment.
4._____________________
Physicians and hospitals also must buy malpractice insurance to protect themselves should they be sued for negligence by patients who feel they have been mistreated or have received inadequate care. The rates for this insurance have been raised very steeply in the last ten years, as patients have become more medically knowledgeable, and as juries sometimes awarded very large amounts of money to injured patients.
5. _____________________
As a result, hospital costs and physicians’ fees rose steadily through the 1990s. Government agencies became convinced that it was necessary to limit rising medical costs. One approach is to require hospitals to prove that a need exists for new buildings and services. Hospitals also have faced pressure to run their operations more efficiently, and to decrease the duration of hospital stays for patients receiving routine treatment or minor surgery.
