单选题 Global climate change, often seen as a process stretching over thousands of years, could in fact occur abruptly and unexpectedly-quickly pushing up temperatures by as much as 18 degrees Fahrenheit and wreaking havoc (大破坏，浩劫) on human society, scientists warned on Wednesday. "Climate change is not always smooth. Sometimes it is abrupt," said Richard Alley, a climate expert at Pennsylvania State University and lead author of a new National Academy of Sciences report on the threat of rapid climatic shifts. "If you have a very large, abrupt change, a lot of people and a lot of ecosystems are going to notice, " he said. "The bigger and faster it is, the harder it will be to deal with. " The new National Academy of Sciences report, released this week, warns that gradual global warming coupled with other human impacts on the environment could "trip the switch" for sudden climate change. At the American Geophysical Union meeting on Wednesday, Alley and other environmental scientists said the geological evidence indicated that such rapid climate shifts had occurred frequently in the past—moving temperatures drastically in the space of just a few decades. "This can happen in less than a human generation, and then it will persist for thousands of years," said David Battisti, an atmospheric scientist at the University of Washington. The most immediate dangers posed by abrupt climate change range are devastating droughts and floods which could seriously affect both water supply and agriculture across vast stretches of the planet. Longer term impacts could include changes in the basic systems which determine regional global temperatures. Scientists believe that the Gulf Stream, a current (水瓶) of warm Atlantic water which now keeps much of Northern Europe temperate, could theoretically reverse direction if enough cool fresh water runs into the north Atlantic from melting ice, a change that would quickly impact European weather.

单选题 Although the American civilization took over and replaced the frontier over a century ago, the heritage of the frontier is still evident in the United States today. Many people are still fascinated by the frontier because it has been particularly important in shaping American values. For many years, the frontier experience was romanticized in popular movies and television shows that featured cowboy heroes fighting Indian villains. Little attention was given to the tragic story of what really happened to Native Americans. Today, most Americans are more aware of the darker side of the settling of the continent, when thousands of Native American Indians were killed, their lands were taken, and much of their culture was destroyed. The American frontier consists of the relatively unsettled regions of the United States, usually found in the western part of the country. Here, both land and life we're more rugged and primitive than in the more settled eastern part. As one frontier area was settled, people began moving farther west into the next unsettled area, sweeping aside the Native Americans as they went. By settling one frontier area after another, Americans moved across an entire continent, 2700 miles wide. They came to believe that it was their destiny to control all the land, and eventually they did. The Native Americans were given small portions of land called reservations to control, but the United States government broke many promises and created much misery for the Indian nations. Recently, Americans have come to a more balanced view of the settling of the West. However, many Americans still see many aspects of the frontier, its people and their beliefs, as good, inspiring examples of traditional American values in their original and purest form. How did the frontier movement, which lasted more than two centuries, help to shape these basic American values? To be sure, the frontier provided many inspiring examples of hard work as forests were turned into towns, and towns into large cities. The competitive race for success was rarely more colorful or adventurous than on the western frontier. Individualism, self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage of America. Throughout their history, Americans have tended to view the frontier settler as the model of the free individual. In the United States, where freedom from outside social controls has traditionally been valued, the frontier has been idealized, and it still serves as a basis for a nostalgic view of the early United States, a simpler time that was lost when the country became urbanized and more complex.

单选题{{B}}Passage Three{{/B}} There's a great story about an old Finnish woman who, without quite realizing it, was using her cell-phone to access the Internet and track her city's public transit system. When asked why she used the wireless Internet so frequently, she replied, "What are you talking about? I don't know anything about this wireless Internet stuff, I just know the bus is here." Regardless of whether you want to admit it, a lot of us are like that old Finnish woman. When it comes to new mobile applications, many of us do not realize the capability and power that we hold, literally, in our hands. What we're looking at today is the mobile Internet in its infancy. Now that using the Inter- net from home or work has saturated much of society, the next logical step is to be able to use the Net when you're away from your desktop or laptop. Speech recognition is one way to do this, and there are a number of services, collectively called the "voice Web", that will make this possible. All you do is use a phone or wireless device to call a phone number, and speak commands to an intuitive system. It will then give you the information you're seeking, using either a synthesized voice or an audio file. In the United States and Europe, the hot technology for wireless devices is called WAP (Wireless Application Protocol), which is being considered as the world standard．WAP is supported by major phone companies including Nokia, Motorola and Ericsson, and is simply a means of transmitting information, much like HTML is a means of communicating on the Internet. Currently, wireless Internet connections may give you news, sports scores, stock quotes, and the weather if you're lucky. But if you've ever used this technology, you know it's slow, costly and doesn't seem worth the time and effort, if it works at all. "The mobile Internet was never designed to take over surfing the Web from a computer," explains Cherie Gary, spokes woman at Nokia. All of this technology points to easier living. Perhaps you'll need to find a restaurant for an occasional business meeting. You'll press a button on your mobile phone, and access the Internet to pull up a list of great restaurants in your immediate area．You'll hit another button, say a few words into tile handset and you've got a reservation for four.
