单选题The Food and Drug Administration said Wednesday that it is trying to track down as many as 386 piglets that may have been genetically engineered and wrongfully sold into the U.S. food supply. The focus of the FDA investigation is pigs raised by researchers at the University of Illinois in Urbana Champaign. They engineered the animals with two genes: One is a cow gene that increases milk production in the sow. The other, a synthetic gene, makes the milk easier for piglets to digest. The goal was to raise bigger pigs faster. There has been no evidence that either genetically altered plants or animals actually trigger human illness, but critics warn that potential side effects remain unknown. University officials say their tests showed the piglets were not born with the altered genes, but FDA rules require even the offspring of genetically engineered animals to be destroyed so they don' t get into the food supply. The FDA, in a quickly arranged news conference Wednesday prompted by inquiries by USA TODAY, said the University of Illinois will face possible sanctions and fines for selling the piglets to a livestock broker, who in turn sells to processing plants. Both the FDA and the university say the pigs that entered the market do not pose a risk to consumers. But the investigation follows action by the U.S. Department of Agriculture in December to fine a Texas company that contaminated 500,000 bushels of soybeans with com that had been genetically altered to produce a vaccine for pigs. Critics see such cases as evidence of the need for more government oversight of a burgeoning area of scientific research. "This is a small incident, but it's incident like this that could destroy consumer confidence and export confidence," says Stephanie Childs of the Grocery Manufacturers of America. "We already have Europe shaky on biotech. The countries to whom we export are going to look at this." The University of Illinois says it tested the DNA of every piglet eight times to make sure that the animal hadn't inherited the genetic engineering of its mother. Those piglets that did were put back into the study. Those that didn' t were sold to the pig broker. "Any pig who' s tested negative for the genes since 1999 has been sent off to market," says Charles Zukoski, vice chancellor for research. But FDA deputy commissioner Lester Crawford says that under the terms of the university's agreement with the FDA, the researchers were forbidden to remove the piglets without FDA approval. "The University of Illinois failed to check with FDA to see whether or not the animals could be sold on the open market. And they were not to he used under any circumstance for food." The FDA is responsible for regulating and overseeing transgenic animals because such genetic manipulation is considered an unapproved animal drug.

An avid Bush supporter who already has
25 shopping malls to his name, Congel himself is not a man you would expect to
entertain an eccentric clean-energy vision. The project -- Destiny U.S.A., a
mega-mall -- first seized him in 2001, soon after 9/11 ---and after the project
was under way -- during a visit to the D-Day beaches in Normandy. "There I was
looking at those pure white graves of tens of thousands of kids that died for
freedom," Congel reflects, sitting on the veranda of his 6,000-acre farm just
outside Syracuse, where he has imported Russian wild boar and other exotic game
for hunting. "Today our kids are dying in a war for oil. Petroleum addiction is
destroying our country, our economy, our environment," Several
months after returning from Normandy, Congel announced that not a drop of fossil
fuel would be used in the making of Destiny. Almost overnight the mission of the
project changed. It went from the mall that could save the depressed economy of
Syracuse to the mall that could save America by establishing a new model for
green commercial development. But will shoppers actually want to travel from far
and wide to a little-known city's eco-friendly mall? And even with the green tax
benefits, it is vastly more expensive to power Destiny with renewable sources
than with conventional grid energy -- so where's the financial logic?
" Here's where Congel's schemes to create "monster
profits" come in. Intel, Clear Channel, Cisco, Sony and Microsoft are among the
brands that Destiny has recruited to supply its retail, entertainment, security
and energy technologies. Many suppliers are planning to build local offices that
will aid the Syracuse economy, and all have agreed to participate in the on-site
development of new technologies that could be tested on the captive audience of
mall-goers. (Congel will be a co-owner of the patents on all inventions.) A
group of companies hopes to perfect a new wireless radio frequency
identification technology to enable customers to purchase items instantly
without waiting in line. The Department of Homeland Security and A.D.T., a
home-security company, have discussed testing new devices that will track all
visitors entering and leaving the mall.

单选题 The cash-for-clunkers program turned out to be a boon for
Asian automakers and the small cars they specialize in. While American
government officials hailed the monthlong program, which ended this week, as an
overall stimulus to the economy, the biggest winner was Toyota, which accounted
for 19 percent of all sales and had two of the top three best- selling
models. Detroit's three automakers — General Motors, Ford and
Chrysler — accounted for 38.6 percent of the vehicles sold. That figure is
substantially less than the 45 percent combined market share that the Detroit
companies posted in the first seven months of the year, while Japan's largest
automakers — Toyota, Honda and Nissan — sold 41 percent of the new vehicles in
the program, compared with the 34 percent combined share they had through July
of this year. The Toyota Corolla was the top seller, followed by the Honda
Civic, Toyota Camry, Ford Focus and Hyundai Elantra. The
success of Toyota and the other Asian automakers was driven by the type of cars
in their showrooms. Participants in the clunkers program clearly were interested
in downsizing to smaller, more fuel-efficient vehicles. About 84 percent of the
clunkers traded in were trucks, and 59 percent of the vehicles purchased were
cars. The interest in small cars, however, could be a hopeful
sign for the American auto companies as well. Ford is betting that consumer
tastes will continue to shift away from big vehicles, and is bringing out new
versions of the Focus and Fiesta subcompact. G.M. and Chrysler have indicated
that their postbankruptcy dealer showrooms will feature more small cars — and
fewer trucks. Over all, the clunker program will have an impact
on lowering fuel consumption, albeit a small one given the number of vehicles
involved. The average fuel economy of the vehicles turned in was just under 16
miles per gallon, compared with an average of almost 25 miles per gallon tot
vehicles bought in the program. A preliminary analysis of the
program by the Obama administration said that third- quarter economic growth has
been 0.4 percent higher because of auto sales in July and August. In addition,
G.M., Ford and Honda all announced that they would increase production at some
United States plants because of the increased demand generated by cash for
clunkers. Virtually every automaker reported increased showroom
traffic because of the program. Just getting prospective buyers back into
dealerships brought some measure of relief to an industry stuck in its worst
sales slump in 25 years. Industry analysts said the surge in
interest would be followed by a letdown now that the program is over. "Cash for
clunkers distorted the market in a way that benefited the industry for four
weeks," said Jeremy Anwyl, chief executive of the auto-research Web site
Edmunds. com. "Now the payback begins." Mr.Anwyl predicted that consumers might
face higher prices on some models that were depleted by clunker sales. Also,
manufacturers have little incentive to provide their own sales incentives
because inventories are low.

单选题{{B}}TEXT D{{/B}} The period of adolescence,
i.e. , the person between childhood and adulthood, may be long or short,
depending on social expectations and on society's definition as to what
constitute maturity and adulthood. In primitive societies adolescence is
frequently a relatively short period of time, while in industrial societies with
patterns of prolonged education coupled with laws against child labor, the
period of adolescence is much longer and may include most of the second decade
of one's life. Furthermore, the length of the adolescent period and the
definition of adulthood status may change in a given society as social and
economic conditions change. Examples of this type of change are the
disappearance of the frontier in the latter part of the nineteenth century in
the United States, and more universally, the industrialization of an
agricultural society. In modern society, ceremonies for
adolescence have lost their formal recognition and symbolic significance and
there no longer is agreement as to what constitutes initiation ceremonies.
Social ones have been replaced by a sequence of steps that lead to increased
recognition and social status. For example, grade school graduation, high school
graduation and college graduation constitute such a sequence, and while each
step implies certain behavioral changes and social recognition, the significance
of each depends on the socio-economic status and the educational ambition of the
individual. Ceremonies for adolescence have also been replaced by legal
definitions of status roles, fights, privileges and responsibilities. It is
during the nine years from the twelfth birthday to the twenty-first that the
protective and restrictive aspects of childhood and minor status are removed and
adult privileges and responsibilities are granted. The twelve-year-old is no
longer considered a child and has to pay full rare for train, airplane, theater
and movie tickets. Basically, the individual at this age loses childhood
privileges without gaining significant adult rights. At the age of sixteen the
adolescent is granted certain adult rights which increases his social status by
providing him with more freedom and choices. He now can obtain a driver's
license; he can leave public schools; and he can work without the restrictions
of child labor laws. At the age of eighteen the law provides adult
responsibilities as well as rights; the young man can now be a soldier, but he
also can marry without parental permission. At the age of twenty-one the
individual obtains his full legal rights as an adult. He now can vote, he can
buy liquor, he can enter into financial contracts, and he is entitled to run for
public office. No additional basic rights are acquired as a function of age
alter majority status has been attained. None of these legal previsions
determine at what point adulthood has been reached but they do point to the
prolonged period of adolescence.
