听力原文：To extinguish different kinds of fires, several types of fire extinguishers have
听力原文： To extinguish different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used to cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
(30)
A．Separating the fire.
B．Reducing the heat.
C．Removing the fuel
D．Cutting off the oxygen.

Despite a cooling of the economy, hightechnology companies are still crying out for skill
Despite a cooling of the economy, high-technology companies are still crying out for skilled workers. The Information Technology Association of America projects that more than 800, 000 technology jobs will go unfilled next year. The lack of qualified workers poses a huge threat to the U. S. economy.
The most commonly cited reason for this state of affairs is that the country's agrarian-age (农村时代) education system fails to prepare students in the primary and secondary grades for the 21st century work. Yet an inadequate and outmoded education system is only part of the problem. A less tangible (明确的) but equally powerful cause is an antique (过时的) classification system that divides the workforce into two camps; white-collar knowledge workers and blue-collar manual laborers.
Blue-collar workers emerged in the United States during the Industrial Age as work moved from farms to factories. White-collar office workers became a significant class in the twentieth century, outnumbering(多于) the blue-collar workers by mid-century. Corporations increasingly require a new layer of knowledge worker; a highly skilled multi-disciplined talent, who combines the mind of the white-collar worker with a solid grounding in mathematics and science (physics, chemistry, and biology). These "gold-collar" workers—so named for their contributions to their companies and to the economy as well as for their personal earning ability—apply their knowledge to technology.
The gold-collar worker already exists in a wide range of jobs. The maintenance technician who tests and repairs aircraft systems at American Airlines; the network administrator who manages systems and network operations at Procter & Gamble(宝洁公司) ; the engineering technologist who assists scientists at Sandia National Laboratories; and the advanced-manufacturing technician at Intel can all be regarded as gold-collar workers.
What does the word "projects" in the first paragraph mean？
A．Throws
B．Predicts
C．Concludes
D．Claims

Seven Ways to Save the World
Forget the old idea that conserving energy is a form. of self-denial -- riding bicycles, dimming the lights, and taking fewer showers. These days conservation is all about efficiency: getting the same -- or better -- results from just a fraction of the energy. When a slump in business travel forced Ulrich Romer to cut costs at his family-owned hotel in Germany, he replaced hundreds of the hotel's wasteful light bulbs, getting the same light for 80 percent less power. He bought a new water boiler with a digitally controlled pump, and wrapped insulation around the pipes. Spending about ？100,000 on these and other improvements, he slashed his ？90,000 fuel and power bill by ？60,000 As a bonus, the hotel's lower energy needs have reduced its annual carbon emissions by more than 200 metric tons. "For us, saving energy has been very, very profitable," he says. "And most importantly, we're not giving up a single comfort for our guests."
Efficiency is also a great way to lower carbon emissions and help slow global warming. But the best argument for efficiency is its cost -- or, more precisely, its profitability. That's because quickly growing energy demand requires immense investment in new supply, not to mention the drain of rising energy prices.
No wonder efficiency has moved to the top of the political agenda. On Jan. 10, the European Union unveiled a plan to cut energy use across the continent by 20 percent by 2020. Last March, China imposed a 20 percent increase in energy efficiency by 2020. Even George W. Bush, the Texas oilman, is expected to talk about energy conservation in his State of the Union speech this week.
The good news is that the world is full of proven, cheap ways to save energy. Here are the seven that could have the biggest impact:
Insulate
Space heating and cooling eats up 36 percent of all the world's energy. There's virtually no limit to how much of that can be saved, as prototype "zero-energy homes" in Switzerland and Germany have shown. There's been a surge in new ways of keeping heat in and cold out (or vice versa). The most advanced insulation follows the law of increasing returns: if you add enough, you can scale down or even eliminate heating and air-conditioning equipment, lowering costs even before you start saving on utility bills. Studies have shown that green workplaces (ones that don't constantly need to have the heat or air-conditioner running) have higher worker productivity and lower sick rates.
Change Bulbs
Lighting eats up 20 percent of the world's electricity, or the equivalent of roughly 600,000 tons of coal a day. Forty percent of that powers old-fashioned incandescent light bulbs -- a 19th-century technology that wastes most of the power it consumes on unwanted heat.
Compact fluorescent lamps, or CFLs, not only use 75 to 80 percent leas electricity than incandescent bulbs to generate the same amount of light, but they also last 10 times longer, Phasing old bulbs out by 2030 would save the output of 650 power plants and avoid the release of 700 million tons of carbon into the atmosphere each year.
Comfort Zone
Water boilers, space heaters and air conditioners have been notoriously inefficient. The heat pump has altered that equation. It removes heat from the air outside or the ground below and uses it to supply heat to a building or its water supply. In the summer, the system can be reversed to cool buildings as well.
Most new residential buildings in Sweden are already heated with ground-source heat pumps. Such systems consume almost no conventional fuel at all. Several countries have used subsidies to jumpstart the market, including Japan, where almost 1 million heat pumps have been installed in the past two years to heat water for showers and hot tubs.

A．Raising efficiency.
B．Cutting unnecessary costs.
C．Finding alternative resources.
D．Sacrificing some personal comforts.
