单选题{{B}}第二篇{{/B}} On a September day in 1991，two Germans were climbing the mountains between Austria and Italy．High up on a mountain pass，they found the body of a man lying on the ice．At that height(10，499 feet，or 3，200 meters)，the ice is usually permanent，but 1991 had been an especially warm year．The mountain ice had melted more than usual and so the body had come to the surface． It was lying face downward．The skeleton(骨架) was in perfect condition，except for a wound in the head．There was still skin on the bones and the remains of some clothes．The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots．Nearby was a pair of gloves made of tree bark(树皮) and a holder for arrows． Who was this man? How and when had he died? Everybody had a different answer to these questions．Some people thought that it was from this century，perhaps the body of a soldier who died in World War I，since several soldiers had already been found in the area．A Swiss woman believed it might be her father，who had died in those mountains twenty years before and whose body had never been found．The scientists who rushed to look at the body thought it was probably much older，maybe even a thousand years old． With modern dating techniques，the scientists soon learned that the Iceman was about 5，300 years old．Born in about 3300 B.C.，he lived during the Bronze Age in Europe．At first scientists thought he was probably a hunter who had died from an accident in the high mountains．More recent evidence，however，tells a different story．A new kind of X-ray shows an arrowhead still stuck in his shoulder．It left only a tiny hole in his skin，but it caused internal damage and bleeding．He almost certainly died from this wound，and not from the wound on the back of his head．This means that he was probably in some kind of a battle．It may have been part of a larger war，or he may have been fighting bandits．He may eyen have been a bandit himself． By studying his clothes and tools，scientists have already learned a great deal from the Iceman about the times he lived in．We may never know the full story of how he died，but he has given us important clues to the history of those distant times．

Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from' Sussex University's School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants' growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.

单选题But for some teachers, the learning curve with the device is steep, and a generation gap has opened with teachers who are still accustomed to writing lesson plans with a pen and paper. Many older educators are" Petrified" (吓呆的，惊呆的) of the boards, says Peter Kornicker, a media specialist at P. S. 161 in Harlem, where despite a student poverty rate of 98 percent, all 35 classrooms are equipped with touchscreens. "Always, it comes back to the ability of teachers to leverage this technology, "says Andy Rotherham of Education Sector, a Washington, D. C. - based think tank. "We have to train them to use it.

单选题 Weather Map A weather map is an important tool for geographers. A succession of three of four maps presents a continuous picture of weather changes. Weather forecasts are able to determine the speed of air masses and fronts; to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day "outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlo6ks are based upon an analysis of the upper air levels with often Set the stage for the development of air masses, fronts, and storms. Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weather modification studies. But the limitations of weather modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographical precipitation on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.
