单选题The wet volcanic ash that covered a Maya village in Central America in about AD 595 coated and preserved everyday objects beans, chilies, rope, gourds, even unwashed dishes -- just as they had been left, giving archaeologists a rare chance to learn about the everyday lives of the people of this pre-Columbian village. Exploration of the site, which is located in E1 Salvador and has been given the name Joya de Ceren, is now in its eighth season, and archaeologists are continuing to make new finds. The volcanic eruption that entombed Ceren more than 1,400 years ago began when lava pushed its way close enough to the surface to create a great explosion of steam and. ash that was centered just north of the village. The archaeologists have not found the remains of any human beings killed by the eruption in Ceren, suggesting that they had enough warning to flee. The eruption buried Ceren in a layer of ash 4 to 6 m (13 to 20 ft) deep over a period of a few days. One of the most striking of the conclusions drawn from the Ceren site is that the people of this ancient village lived more comfortably than average Salvadorans do today. Ceren's architecture, crafts, and agriculture were surprisingly sophisticated and varied. They ate a rich variety of foods, had spacious, well-ventilated living and working quarters, and lavishly decorated many of their ceramic items. Yet Caren was an average farming village, not a seat of the ruling class or a regional center of commerce, archaeologists said. The village of Ceren was rediscovered in 1976 when a bulldozer operator knocked into the wall of one of the structures. Grasses that made up the thatched roof of the dwelling were still preserved, leading an archaeologist to conclude that the structure was recent. After two years, anthropologist Payson D. Sheets of the University of Colorado at Boulder discovered the antiquity of the structures when he dated a sample of thatch to about 1,400 years ago. Sheets was able to survey the site for only a few years before the civil war in El Salvador made it too dangerous to continue. The archaeologists left the site, located northwest of San Salvador, the capital, in 1980 and did not return until 1989. Since then, archaeologists led by Sheets have returned each year. As of spring 1997, they had digged 12 buildings, including a community hall, living quarters, kitchens, storerooms, a religious hall, a sauna, and even a small building believed to be the workplace of a shaman (a priest who uses magic). The smallest objects of daily life were preserved, sometimes as actual organic matter such as seeds or stems, sometimes as impressions in the ash such as that of a cornstalk or a squash. By sending radar signals through the ground in order to detect buried objects, archaeologists in I994 located 22 additional structures still buried in ash. Archaeologists at the site have found the remains of animals including dogs, deer, and a duck tied to a pole. All that remains of the people of Ceren, however, are their footprints, and a few teeth, believed to have been tossed on a roof for good luck. When the teeth were found, workers told Sheets that throwing teeth on the roof is a tradition still practiced by some people in rural El Salvador today.

单选题Ode to the West Wind was written by
单选题Forced to pay for once-free sandwich toppings and twice as much for some steak cuts, shoppers are wondering whether higher grocery bills and restaurant tabs truly reflect the trickle down of a global rise in food prices.
Veronica Banks, who lives outside St. Louis, said she suspects that neighborhood comer stores are charging more for many items under the assumption that customers won"t pay the bus fare to go bargain hunting.
Without a doubt, basic economic principles account for most of the increase in the wholesale cost of food worldwide. Bad weather has hurt crops. Economic prosperity has driven up demand in developing countries. And soaring fuel prices have raised transportation costs. Mix in investors being on continued food-price inflation, and you have a recipe for a run-up.
Foodstuffs from rice to steak cost more than a year ago—so much, in fact, that some consumers don"t quite believe it all adds up. But food retailers say that consumers" suspicions of gouging are unjustified and that, if anything, they have refrained from passing along their extra costs.
"People have told me I nickel-and-dime them," said Kate Oncel, director of operations at the Brown Bag, a dell in Washington. "They don"t understand the position we"re in" of paying dramatically more for meat, produce, bread, packaging and deliveries.
Retailers raising prices and shoppers, in turn, raising eyebrows are reasonable and established responses, say economists and historians. While competitive pressures keep most businesses from taking advantage of their customers, some see an opportunity to push prices beyond justified levels.
Forgoing pricier items are adjustments many Americans can afford and stomach, especially relative to the crises in the more than 30 countries where food protests have raged.
But in the U.S., customers notice when the grocery bill stays the same but the take-home haul lightens. Conversely, most remain quiet when prices stay the same or drop. "I get upset thinking about how much we have to pay for things, but then I feel guilty when I see other nations that are dealing with horrible poverty," Helen Strouss of La Mirada, California, said last week at an Albertson"s grocery store.
Consumers forking over more to fill their gas tanks and stomachs may feel like they"ve been hit with an unprecedented one-two punch. But the food-fuel wallop has landed before, said David Hackett Fischer, a professor of history at Brandeis University in Waltham, Massachusetts. In the 13th century, demand for firewood and grain led to broader price hikes. And sellers have taken advantage of the system throughout the 20th century as free market ideas removed many price controls, he said.
The nation"s 945,000 restaurants expect to set a sales record of $558 billion this year, said Hudson Riehle, senior vice president of research at the National Restaurant Association. Restaurants probably will make some changes on the plate, rejiggering portions, and on the restaurant floor, using more technology to gain efficiency and training programs to bolster sales, Riehle said.
At the Brown Bag, where cucumber toppings now cost 50 cents, Oncel has not raised the overall price of sandwiches and salads but said she will if food commodities and gas prices don"t fall.
At nearby TJ"s Gourmet Deft, owner Terry Chung said customers can expect to pay 30 cents more per sandwich and up to 40 cents more per pound on the salad bar if economic conditions don"t change. His profits are down about 25 percent in recent months, with the biggest cost increase coming in delivery fuel surcharges, which have roughly doubled to $4.50 per order.
The hesitancy to raise prices unnecessarily is rooted in competition, said Ann Owen, an economics professor at Hamilton College in Clinton, New York, and a former economist at the Federal Reserve. But if the cost increases are more permanent, retailers can confidently raise prices, she added. But that can"t insulate them from skeptical shoppers who see overblown hikes and a panic-hungry media.

单选题{{B}}TEXT C{{/B}} Once found almost entirely
in the western United States and in Asia, dinosaur fossils are now being
discovered on all seven continents. A host of new revelations emerged in 1998
that promise to reshape scientists' views of dinosaurs, including what they
looked like and when and where they lived. It is doubtful that
Tyrannosaurus Rex had lips or that Triceratops had cheeks, says Lawrence Witmer,
an assistant professor of anatomy at Ohio University in Athens, Ohio. Witmer was
a leading researcher for a study on dinosaur anatomy that was presented at the
annual meeting of the Society for Vertebrate Paleontology, which concluded on
October 3 in Snowbird, Utah. Witmer's study reached its
conclusions by using high-tech computerized axial to mograply (CT or CAT) scans
along with comparative anatomy studies. For example, the theory that Triecratops
and similar dinosaur species had cheeks was based on past comparisons with
mammals such as sheep. But Witmer's carful analysis found the structure of the
triceratops jaw and skull made it more likely that Triceratops had a beak like
that of an eagle. Witmer said that scientists should use birds and crocodiles as
models when researching the appearance of dinosaurs. In early
October scientists announced that they had confirmed the diseovery of a new type
of ceratopsian dinosaur. The dinosaur's hones, found in New Mexico in 1996, are
forcing paleontologists to rethink their theories about when ceratopsians
migrated to what is now North America. Scientists previously
thought that ceratopsians, the group that included the well-known Tricer amps,
arrived in North America from Asia between 70 million and 80 million years ago.
During this time, the late Gretaceous Period, the earth's two supercontinents --
Laurasia in the north and Gondwanaland in the south -- were in the process of
pulling apart, cutting dinosaur populations off farm each other and interrupting
migratory patterns. The fossilized bones, found by
eight-year-old Christopher Wolfe and his father, paleontologist Doug Wolfe of
the Mesa Southwest Museum in Arizona, date to about 90 million years ago. This
could mean that ceratopsians originated in North America and migrated to Asia
rather than the reverse, paleontologists said. Doug Wolfe named the important
new species of dinosaur Zuniceratops christopheri after his son.
An expedition from the Universities of Alaska in Anchorage and Fairbanks
has discovered a region in remote northern Alaska so rich in fossilized dinosaur
tracks that team members dubbed it the "dino expressway". The trampled area was
found during the summer of 1998 in Alaska's North Slope near the Brooks
Range. The team found 13 new track sites and made casts from the
prints of five different types of dinosaurs. The rock in which the prints were
found dates to more than 100 million years ago, or about 25 million years older
than the previously discovered signs of dinosaurs in the Arctic region.
Paleontologists said that the new findings provide important evidence that
dinosaurs migrated between Asia and North America during the early and
mid-Cretaceous Period, before Asia split off into its own continent.
Two rich fossil sites in the hills of Bolivia have been recently
discovered, exciting paleontologists and dinosaur buffs. This discovery includes
one of the most spectacular dinosaur that was ever found. The
discovery of a large site in the mountain region of Kila Kila in southern
Bolivia was announced in early October. Here scientists found the tracks of at
least two unknown species of dinosaur. These included a large quadruped
(four-footed) dinosaur that was probably about 20m (a bout 70ft,)
long. The other site, located not far from the Bolivian city of
Sucre, was uncovered in a cement quarry by workers several years ago but was not
brought to paleontologists' attention until the mid die of 1998. The site
features a vertical wall covered with thousands of dinosaur prints representing
more than 100 different species. The tracks date back to between 65 million and
70 million years ago. Since dinosaurs are believed to have died out around 65
million years ago, the prints were likely made by some of the last dinosaurs on
earth. Scientists speculated that the tracks were made at the
edge of a lake or swamp and were then hardened and preserved. The rock
containing the tracks was then pushed into a vertical position over millions of
years of geologic activity. Dinosaur eggs have also been found at the site,
which paleontologists are working to preserve before it falls victim to erosion.
Paleontologists hope to study the site and learn about the diet and physical
characteristics of the dinosaurs that are represented there.
