背诵篇章 scrapers put a severe strain on a citys san s, too. If fully occupied, the two world Trade Center towers in New York City would alone generate 2.25 million gallons of raw sewage each year-as much as a city the size of Stanford, Connecticut which has a population of more than 109, 000. 14 A Rare Fossil Record The preservation of embryos and juveniles is a rate occurrence in the fossil record. The tiny delicate skeletons are usually scattered by scavengers or destroyed by weathering before they can be fossilized. Ichthyosaurs had a higher chance of being preserved than did terrestrial creatures because, as marine animals, they tended to live in environments less subject to erosion Still, their fossilization required a suite of factors: a slow rate of decay of soft tissues, little scavenging by other animals, a lack of swift currents and waves to jumble and carry away small bones, and fairly rapid burial. Given these factors, some areas have The deposits at Holzmaden, Germany, present an interesting case for analysis. The ichthyosaur remains are found in black, bituminous marine shales deposited about 190 million years ago. Over the years, thousands of specimens of marine reptile fish and invertebrates have been recovered fom these rocks. The quality of preservation is outstanding but what is even more impressive is the number of ichthyosaur fossils containing preserved embryos. Icthyosaurs with embryos have been reported from 6 different levels of the shale in a small area around Holzmaden, suggesting that a specific site was used by largenumbers of ichthyosaurs repeatedly over time. The embryos are quite advanced in their physical development; their paddles, for example, are already well formed. One specimen is even preserved in the birth canal. In addition, the shale contains the remains of many newborns that are between 20 and 30 inches long Why are there so many pregnant females and young at Holzmaden when they are so rare elsewhere? The quality of preservation is almost unmatched and quarry operations have been carried out carefully with an awareness of the value of the fossils. But these factors do not account for the interesting question of how there came to be such a concentration of pregnant ichthyosaurs in a particular place very close to their time of giving birth 15 The Nobel Academy For the last 82years, Sweden 's Nobel Academy has decided who will receive the Nobel Prize in Literature, thereby determining who will be elevated from the great and the near great to the immortal. But today the Academy is coming under heavy criticism both from the without and from within. Critics contend that the selection of the winners often has less to do with true writing ability than with the peculiar internal politics of the Academy and of Sweden itself. According to Ingmar Bjorksten, the cultural editor for one of the country's two major newspapers, the prize continues to represent what people call a very Swedish se: reflecting Swedish taste The Academy has defended itself against such charges of provincialism in its selection by asserting that its physical distance from the great literary capitals of the world actually serves to protect the Academy from outside influences. This may well be true, but critics respond that this very distance may also be responsible for the Academy 's inability to perceive accurately authentic trends in the literary world Regardless of concems over the selection process, however, it seems that the prize will continue to survive both as an indicator of the literature that we most highly praise, and as an elusive goal that writers seek. If for no other reason, the prize will continue to be desirable for the financial rewards that accompany it not only is the cash prize itself considerable, but it also dramatically increases sales of an authors books 16. the war between Britain and france In the late eighteenth century, battles raged in almost every corner of Europe, as well as in the Middle East, south Africa the WestIndies, and Latin America. In reality, however, there was only one major war during this time, the war between Britain and ce. All other battles were ancillary to this larger conflict, and were often at least partially related to its an tagonist goals and of throughout the continent to thwart Napoleon; through treaties. Britain built coalitions(not dissimilar in concept to todays NATO) guaranteeing British participation in all major European conficts. These two antagonists were poorly matched, insofar as they 6背 诵 篇 章 6 Skyscrapers put a severe strain on a city's sanitation facilities, too.

Still, their fossilization required a suite of factors: a slow rate of decay of soft tissues, little scavenging by other animals, a lack of swift currents and waves to jumble and carry away small bones, and fairly rapid burial. Given these factors, some areas have become a treasury of well-preserved ichthyosaur fossils. The deposits at Holzmaden, Germany, present an interesting case for analysis. The ichthyosaur remains are found in black, bituminous marine shales deposited about 190 million years ago.
