Oil prices have raised overall consumer prices and cut into household purchasing power. So far the higher costs haven't deterred(阻止) buying, even buying of cars and other energy-sensitive items. The major reason for the lack of reaction is that oil is less important to the economy than it once was. Oil, which produced 45% of world energy in 1971, accounted for only 35% in 2003, with increases in nuclear and natural gas use making up the difference.
GM, Ford, and Chrysler suffered as buyers shifted to more fuel-efficient vehicles from Toyota and Honda, but the shift was hot pronounced. Admittedly, light truck sales are holding up in part because manufacturers are offering large discounts to "move the metal", but the fact that buyers are responding to those incentives shows they aren't too scared of gas prices.
Americans continue to spend more than they earn, but gasoline prices will have an effect. Although the April chain store results suggest gasoline prices aren't hurting much yet, eventually Americans will be forced to realize that they have to slow down. We expect the economy to slow in the second half of the year as the impact of higher oil prices sinks in. How much the economy slows will depend on how high oil prices remain. We expect some drop in oil prices by yearend, but I have been saying that for so long even I am starting not to believe it.
The anger against the oil companies is clearly misplaced. Exxon and friends control only a small share of world oil reserves. Most are now in the hands of state-owned oil companies. The recent move by Bolivia to nationalize its industry is only the latest in a long line of similar actions. The history of these enterprises is one of severe underinvestment and mismanagement, which tends to reduce supply and keep prices high. The risk on oil prices is primarily on the high side of our forecast.
Although I think oil prices will drop back in the medium term, to address my serious worries, I'm buying my wife a bike for Mothers' Day.
The economy at the beginning of 2006 is not affected by the high oil price mainly because ______.
A．the warm winter requires less oil to run the heaters
B．the warm winter promotes consumption, across the country
C．people believe that the oil price will drop in near future
D．people don't think the high price will make much of a difference
Experts in education and gerontology(老人医学) say that the number of retired Americans who are spending time—or planning to—on educational pursuits is growing fast. The trend is driven by such factors as increased longevity, people enjoying more years of good health, and a growing realization by many that a retirement into passivity is not only boring but can lead to atrophy(萎缩) of both mind and body. The federal government estimated in 2001 that additional life expectancy for a 65-year-old was 16.4 years for men and 19.4 years for women. That's a lot of time to fill if you're not working and in good health.
Certainly, educational opportunities aimed at the 65-and-older set aren't new. The first" lifelong learning institute" targeted specifically at retirees opened in 1962 at the New School for Social Research in New York, and there are many others that have been around for two decades or more. What's new is the tremendous variety of learning opportunities and places available for those who approach retirement. The options range from one-shot lectures, discussion classes, or day trips organized by a local college or retirement home.
Educational travel is appealing because it combines the exploration of a new place with deepening your understanding of its history, geology, or literature. For those who prefer to stay close to home, many campus-based pro grams are available that offer a college-level curriculum but don't have grades or tests. Perhaps the ultimate commitment to lifelong learning is moving into a retirement community affiliated with an educational institution. For folks who like the idea of living in a campus environment, several retirement villages are built near campuses in Ohio, New York, Virginia, Pennsylvania, and New Hampshire. The programs give residents' access to campus activities, al low them to attend or teach classes, as well as work on joint-research projects with undergrads, graduates, or faculty.
In our shorter-lived-parents' generation, people were often satisfied to define retirement in terms of what they weren't doing—namely, working. But with the possibility of 20 or more years ahead after leaving your primary job or profession, you owe it to yourself to find a positive, enjoyable way to spend your time. Continuing education might be the answer. Not only do you not have to take tests or pull an all-nighter to struggle for a good grade, you can study any topic you want, almost anywhere in the world—and on your own schedule.
More Americans are taking up education after retirements partly because ______.
A．they want to learn what they have no time to learn before retirement
B．they retire at an earlier age with more years left to learn
C．they are more wealthy to afford to continue the education
D．they find learning is a good way to fight against the process of aging
Passage Three Questions 31 to 35 are based on the following passage.
Age has its privileges in America. And one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age—in some cases as low as 55—is automatically entitled to a dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one’s need but by the date on one’s birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses—as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them；yet, millions of Americans above age 60 are healthy and solvent (有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous (同义的). Perhaps that once was true, but today elderly Americans as a group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor, But most of them aren’t.
It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between the generations.
Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another sore point, Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job-thereby lessening employment and promotion opportunities for younger workers.
Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don’t need them.
It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can’t take care of themselves and need special treatment； and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against-discrimination by age.
31. We learn from the first paragraph that ________.
A) offering senior citizens discounts has become routine commercial practice
B) senior citizen discounts have enabled many old people to live a decent life
C) giving senior citizens discounts has boosted the market for the elderly
D) senior citizens have to show their birth certificates to get a discount
Unless you're using a germicidal soap, it usually doesn't kill the bacteria soap simply removes bacteria along with dirt and oil. Neither baths nor showers are all that necessary and unless you're in a Third World country where infectious diseases are common, or you have open sores on your skin, the dirt and bacteria aren't going to hurt. The only reason for showering or bathing is to feel clean and refreshed. There is a physiological basis for this relaxed feeling. Your limbs become slightly buoyant in bathwater, which takes a load off muscles and tension. Moreover, if the water is hotter than normal body temperature, the body attempts to shed heat by expanding the blood vessels near the surface of the skin, lessening the circulatory system's resistance to blood flow, and dropping blood pres sure gently. A bath is also the most effective way to hydrate the skin. The longer you soak, the more water gets into the skin and because soap lowers the surface tension of the water, it helps you hydrate rapidly and remove dry skin flakes.
However, in a bath, all the dirt and grime and the soap in which it's suspended float on the surface. So when you stand up, it covers your body like a film. The real solution is to take a bath and then rinse off with a shower, however, after leaving a tub or freshly ex posed skin becomes a playground for microbes. In two hours, you probably have as many bacteria on certain parts of the body, such as the armpits, as before the bath.
The statement "Americans bathe zealously" (Line 1, Para. 1) is closest to saying.
A．Americans bathe wastefully
B．Americans are rather ambivalent to bathing
C．Americans bathe with intense enthusiasm
D．Americans bathe too much
