69-71. BAD  


解析:

本表格是美國歷次戰(zhàn)爭的開支情況統(tǒng)計。

69. B。細(xì)節(jié)題。從表中可以看出美國內(nèi)戰(zhàn)和第二次世界大戰(zhàn)的費(fèi)用分別占美國年度國民生產(chǎn)總值的104%和103%，超出了它的年度GDP。故選B。

70. A。推測計算題。從常識中可以知道，1951年美國正處在朝鮮戰(zhàn)爭之中，而美國在朝鮮戰(zhàn)爭的花費(fèi)為 $335.9 billion，占它的年度GDP的15%。據(jù)此可以計算出它1951年的 GDP 應(yīng)為 $2.239 trillion。

71. D。事實確認(rèn)題。D項明顯錯誤。Mexican War 和 Spanish American War 兩場戰(zhàn)爭的花費(fèi)占年度的GDP比率相同，但并不等于兩場戰(zhàn)爭的費(fèi)用是一樣的。

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(棕櫚) 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 (障礙)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（藻類）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.．Why does Virgin Airlines try to replace normal fuel with biofuel?

A．To cut down the flight cost of the company.

A．a(chǎn)lter the engine for airplanes

4.．We can infer from the last paragraph that          .

A．there is a long way to go for a complete switch to alternative fuel

B．it won’t be long before alternative fuel comes into use

C．a(chǎn)irlines, oil companies and airplane manufacturers are reliable

D．a(chǎn)lternative fuel has a bright future

5.．Which of the following can best serves as the title of this passage?

A．Biofuel-Alternative Fuel Sources.

B．The First Commercial Flight Powered by Biofuel.

C．How to Reduce CO2 Emissions from Airplanes.

D．Vigin Airlines Trying to Alter Fuel Sources.

A. Using expensive testing equipment

B. Staffing a modern hospital

C. Testing becoming a great help

D. Cost of medical accidents

E. Cost of training medical workers

F. Measures of reducing medical costs

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.
