THE GROWING OF GREEN CARS By W. E. Butterworth 1. Every year, more than a million new cars and trucks hit U.S. highways. They join the countless vehicles already on the road. And one adds to the pollution that darkens our skies. 2. But that soon may change. On the horizon are cars that make little or no pollution at all. They are called “green cars” because they are friendly to our green earth. 3. Most car engines burn gasoline, which adds to the “smog” that dirties our cities. This air pollution—nitrogen oxide and carbon monoxide— hurts humans. It also rises high in the sky where it soaks up heat from the sun. Some scientists say this causes a second problem: the “greenhouse effect,” or warming of the earth. The air has become so bad in California that the state passed a new pollution law. It tells auto makers that some of their new cars must not pollute at all. They will be zero-emission vehicles, or ZEV. Five years from now, in 1998, two of every 100 new cars sold in California must be ZEV. The requirement shoots to one in 10 just after the turn of the century. 4. California does not suffer smog alone. According to the U.S. Environmental Protection Agency (EPA), vehicles nationwide cause 56 percent of cancer-causing air pollutants. “While today’s cars are 80 percent cleaner than 20 years ago,” says the EPA’s Martha Casey, “we have more cars today.” 5. Today, the average family minivan gets only 23 miles per gallon. Some lawmakers in the U.S. Congress want cars nationwide to do better— averaging 40 miles per gallon. That would produce less smog per mile traveled. 6. But reaching that goal will be costly. The Honda Civic VX, for example, gets an astounding 48 miles per gallon. But the equipment making that possible adds almost $2,500 to the car’s price. Few customers want to pay the extra cost. Honda sells far more of a cheaper Civic model that burns more gasoline. 7. Burning less fuel is one way to cut pollution. Another way is to tune engines so they can burn cleaner fuels. These cars, called Flexible Fuel Vehicles, may run on gasoline, hydrogen methanol, ethanol, natural gas, propane gas, or various other fuels. Still, these fuels must be burned. And burning causes pollution. 8. Electric cars don’t burn fuel, so they put out no exhaust at all. They are the cars that companies will build to comply with the stiff, new ZEV laws. 9. Already, companies from Chrysler to MercedesBenz put electric motors in some of their current models, with all new designs to follow. 10. But some people argue that even electric cars aren’t perfect. Why? Because the batteries that run them get their energy from power plants. And power plants often belch their own pollutants into the air. 11. Both lawmakers and automakers agree that there are no easy answers on the road to perhaps the perfect ZEV: an electric car powered by the sun. Much more work is needed to make such an earth-friendly car practical. 12. But with each step—such as models free of chlorofluorocarbon—cars get better. 13. They will have to. Almost a dozen Northeastern states and Washington, D.C., are adopting California’s tough auto standards. That, by one manufacturer’s estimate, means nearly 300,000 electric cars in the United States by 2001—proof that green cars are taking root.

Which summary is the best? Why? 2. Analyze the other three summaries and determine what kinds of mistakes the authors made. SUMMARY 1 “The Growing of Green Cars” describes the serious pollution problem in California and many other states. Since cars and trucks add to the pollution, auto makers are trying to design cars that are environmentally safer. __________________________________ ________________________________________ SUMMARY 2 This article is about how car companies are finally trying to deal with the pollution that their products cause. Since cars and trucks around the country are responsible for over 50 percent of the dangerous pollutants in the air we breathe, I think it is about time that the automobile companies decided to do something to make their vehicles safer for the environment. California has recently passed a law that requires auto makers to produce a certain number of cars that do not pollute the environment at all. Other states are following in California’s footsteps and hopefully, by the year 2000, many cars on the road will not burn any fuel at all. These new electric cars may be the answer to the serious problem of pollution caused by burning fuel. __________________________________ ________________________________________ SUMMARY 3 In “the Growing of Green Cars” (Boys’ Life, May 1993), W. E. Butterworth describes the ways that cars and trucks add to the already high level of air pollution in the United States. According to the U.S. Environmental Protection Agency (EPA), vehicles nationwide cause 56 percent of cancercausing air pollutants. This may soon change as states like California pass laws that require auto makers to produce cars that cause less pollution. The long-term goal is to make zero-emission vehicles (ZEV) that will not pollute the air at all. Within five years, 2 percent of all cars sold in California must be ZEV. This will increase to 10 percent by the year 2000. Even though cars today are 80 percent cleaner than those produced 20 years ago, the problem is worse because of the great increase in the number of cars on the road. The article mentions several ways to cut pollution caused by cars. One way is to produce cars that burn less fuel. A second way is to tune engines so they burn cleaner fuels, such as hydrogen, methanol, ethanol, natural gas, or propane gas. Finally, automobile companies are designing electric cars that do not burn any fuel. Companies such as Chrysler and Mercedes-Benz are already putting electric motors into some of their cars. __________________________________ ________________________________________ SUMMARY 4 In “The Growing of Green Cars” (Boys’ Life, May 1993), W. E. Butterworth discusses the new trends in environmentally safe automobiles called “green cars.” Auto makers are working hard to produce cars that cause less pollution. Their long-term goal is to make zero-emission vehicles (ZEV) to comply with new state laws. The author mentions several ways that car companies can reach their goal, such as designing cars that burn less fuel, tuning engines so they burn cleaner fuels, and producing electric cars that do not burn any fuel. However, none of these solutions is perfect, and all of them are expensive. Although everyone agrees that there are no simple solutions, more and more states are adopting stricter antipollution laws.
