Is the United States Addicted to Gasoline
Used in everything from lipstick and lubricants to motor oil and medications, oil is one product the world just can’t seem to get enough of. The United States especially, which consumes roughly 21 million barrels of the stuff a day, has quite an attachment to this ubiquitous(普遍存在的) product. And while oil can be refined into a variety of products, Americans seem to prefer theirs in the form of gasoline. In fact, the United States consumes more gasoline than South America, Europe, Africa and Asia combined.
So what’s with the United States and its gasoholic tendencies Is the country truly addicted to gasoline, and if so, what factors led it to get hooked
While the United States obviously has quite a fixation with the amber liquid, its fondness for gasoline probably doesn’t fit the official criteria for an addiction. Rather, the affinity is more like a bad habit spurred on by a numb
A. Medication.
B. Lipstick.
C. Lubricant.
D. Gasolin
[单项选择]Today’s low gasoline prices make consumers willing to indulge their preference for larger cars, which consume greater amounts of gasoline as fuel. So United States automakers are unwilling to pursue the development of new fuelefficient technologies aggressively. The particular reluctance of the United States automobile industry to do, so, however, could threaten the industry’s future.
Which of the following, if true, would provide the most support for the claim above about the future of the United States automobile industry
A. A prototype fuel-efficient vehicle, built five years ago, achieves a very high 81 miles per gallon on the highway and 63 in the city, but its materials are relatively costly.
B. Small cars sold by manufacturers in the United States are more fuel efficient now than before the sudden jump in oil prices in 1973.
C. Automakers elsewhere in the world have slowed the introduction of fuel-efficient technologies but have pressed ahead with research and development of them in preparation for a predicted rise in world oil prices.
D. There are many technological opportunities for reducing the waste of energy in cars and light trucks through weight, aerodynamic drag, and braking friction.
E. (E) The promotion of mass transit over automobiles as an alternative mode of transportation has encountered consumer resistance that is due in part to the failure of mass transit to accommodate the wide dispersal of points of origin and destinations for trips.
[简答题]The recent gasoline price hike has brought some unexpected good results--it has spurred consumer interest in small cars that use less fuel. But there’re discriminatory restrictions against small cars in China, for example, in many cities and regions small cars are not allowed to use expressways or enter downtown areas. And consumers are reluctant to choose the small cars. In contrast, the European Commission requires European cars manufacturers to reduce carbon dioxide emissions for passenger cars, forcing automakers to produce lighter cars with smaller engines.

[单项选择] Petroleum products, such as gasoline, kerosine, home heating oil, residual fuel oil, and lubricating oil, all come from one source ― crude oil found below the earth’’ s surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25 000 feet into the earth’’s interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those generating oil. Pressure at the source or pumping forces crude oil to the surface.
Crude oil wells flow at varying rates, from ten to thousands of barrels per. hour. Petroleum products are always measured in 42-gallon barrels.
Petroleum products are different in physical appearance: thin, thick, transparent or opaque, but their chemical composition is made up of only two elements: carbon and hydrogen, which form compounds called hydrocarbons. Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements ar
A. By expansion of the hydrocarbons.
B. By pressure and pumping.
C. By vacuum created in the drilling pipe.
D. By expansion and contraction of the earth’’s surface.
