单选题The devastating effects of earthquakes on human lives and property have encouraged the search for earthquake prediction. This challenge remains and contemporary seismologists continue to seek reliable methods for pinpointing the time, place and magnitude of individual quakes. One prediction technique involves an analysis of the recurrence rates of earthquakes as indicators of future seismic activity. Earthquakes are concentrated in certain areas of the world where tectonic plates such as the Pacific Plate, the Eurasian Plate and the African Plate meet and create fault zones and it is in these areas that seismologists focus their investigations. The tectonic plate model provides another tool for earthquake prediction by calculating the accumulated strain at plate boundaries. When the strain reaches a certain magnitude the pressure must be released and it is therefore hypothesized that in such eases an earthquake is imminent. The search for premonitory phenomena has received particular attention. In contrast to the ancient Greeks and Romans, who relied on the howling of dogs as a warning sign, modern seismologists have focused on physical evidence for an impending earthquake. Evidence of plate strain can be found by measuring relative movements in geodetic stations, while chemical changes also offer signals for seismologists. Using chemical-detection techniques, scientists established a link between the rise in the concentration of radon gas in mineral water and the subsequent earthquake. Analysis of the changes in magnetic properties and conductivity of rocks provides further data for prediction. The electrical and magnetic properties of crustal rocks particularly sensitive to strain and studies measuring changes which occur in these properties have provided promising results. The conductivity of crustal rock is determined by the degree to which the rock is saturated with fluid and the electrolytic properties of those fluids. Before large earthquakes, small fractures develop in rocks, which change the quantity of fluid present. These changes can be measured and provide useful predictive data. However, similar changes in the fluid-bearing capacity of rock can occur as a result of other factors such as changes in the water table, and therefore this technique is not entirely reliable. The belief that the behavior of birds, eats and dogs provides evidence of imminent earthquakes has recently gained credence. It is hypothesized that the animals are sensitive to the seismic waves which precede major quakes. In zones where earthquakes are known to occur, improved construction techniques can significantly reduce the effects of seismic waves. If more accurate information regarding the time and magnitude were available, governments could take even more effective measures to reduce the impact on human life. If an entirely accurate prediction technique became available, there would be significant social and political implications. An earthquake prediction in a major urban area would require governments to provide an effective evacuation strategy, necessitating massive resource and political will.

单选题Whenever the political laws of the United States are to be discussed, it is with the doctrine of the sovereignty of the people that we must begin. The principle of the sovereignty of the people, which is always to be found, more or less, at the bottom of almost all human institutions, generally remains there concealed from view. It is obeyed without being recognized, or if for a moment it is brought to light, it is hastily cast back into the gloom of the sanctuary. "The will of the nation" is one of those phrases, that have been most largely abused by the wily and the despotic of every age. Some have seen the expression of it in the purchased suffrages of a few of the satellites of power; others, in the votes of a timid or an interested minority; and some have even discovered it in the silence of a people, on the supposition that the fact of submission established the right to command. In America the principle of the sovereignty of the people is neither barren nor concealed, as it is with some other nations; it is recognized by the customs and proclaimed by the laws; it spreads freely, and arrives without impediment at its most remote consequences. If there is a country in the world where the doctrine of the sovereignty of the people can be fairly appreciated, where it can be studied in its application to the affairs of society, and where its dangers and its advantages may be judged, that country is assuredly America. It has been observed that, from their origin, the sovereignty of the people was the fundamental principle of most of the British colonies in America. It was far, however, from then exercising as much influence on the government of society as it now does. Two obstacles, the one external, the other internal, checked its invasive progress. It could not ostensibly disclose itself in the laws of colonies which were still forced to obey the mother country, it was therefore obliged to rule secretly in the provincial assemblies, and especially in the townships. American society at that time was not yet prepared to adopt it with all its consequences. Intelligence in New England and wealth tended to keep the exercise of social power in the hands of a few. Not all the public functionaries were chosen by popular vote, nor were all the citizens voters. The electoral franchise was everywhere somewhat restricted and made dependent on a certain qualification. Which was very low in the North and more considerable in the South. The American Revolution broke out, and the doctrine of the sovereignty of the people came out of the townships and took possession of the state. Every class was enlisted in its cause; battles were fought and victories obtained for it; it became the law of the laws.

单选题{{B}}Passage Three{{/B}} In the early clays of the United States, postal charges were paid by the recipient and charges varied with the distance carried. In 1825, the United States Congress permitted local postmasters to give letters to mail carriers for home delivery, but these carriers received no government salary and their entire compensation on what they were paid by the recipients of individual letters. In 1847 the United States Post Office Department adopted the idea of a postage stamp, which of course simplified the payment for postal service but caused grumbling by those who did not like to prepay. Besides, the stamp covered only delivery to the post office and did not include carrying it to a private address. In Philadelphia, for example, with a population of 150000, people still had to go to the post office to get their mail. The confusion and congestion of individual citizens looking for their letters was itself enough to discourage use of the mail. It is no wonder that, during the years of these cumbersome arrangements, private letter-carrying and express businesses developed. Although their activities were only semilegal, they thrived, and actually advertised that between Boston and Philadelphia they were a half-day speedier than the government mail. The government postal service lost volume to private competition and was not able to handle efficiently even the business it had. Finally, in 1863, Congress provided that the mail carriers who delivered the mail from the post offices to private addresses should receive a government salary, and that there should be no extra charge for that delivery. But this delivery service was at first confined to cities, and free home delivery became a mark of urbanism. As late as 1887, a town had to have 10000 people to be eligible for free home delivery. In 1890, of the 75 million people in the United States, fewer than 20 million had mail delivered free to their doors. The rest, nearly three-quarters of the population, still received no mail unless they went to their post office.

单选题There are only three available strategies for controlling cancer: prevention, screening and treatment. Lung cancer causes more deaths than any other types of cancer. A major cause of the disease is not 1 known; there is no good evidence that screening is much help; and treatment fails in about 90 percent of all cases. At present, therefore, the main strategy must be 2 This may not always be true, of course, as for some other types of cancer, researches over the past few decades have produced (or suggested) some importance in prevention, screening or treatment. 3 , however, we consider not what researchers may one day offer but what today"s knowledge could already deliver that is not being delivered, then the most practical and cost-efficient opportunities for avoiding premature death from cancer, especially lung cancer, probably involve neither screening nor improved 4 , but prevention. This conclusion does not depend on the unrealistic assumption that we can eliminate tobacco. It merely assumes that we can reduce cigarette sales appreciably by raising prices or by 5 on the type of education that already appears to have a positive effect on cigarette assumption by white-collar workers and that we can substantially reduce the amount of tar 6 per cigarette. The practicability of preventing cancer by such measures applies not only in those countries, such as, the United States of America, because cigarette smoking has been common for decades, 25 to 30 percent of all cancer deaths now involves lung cancer, but also in those where it has become 7 only recently. In China, lung cancer as yet accounts for only 5 to 10 percent of all cancer deaths. This is because it may take as much as half a century for the rise in smoking to increase in the incidence to lung cancer. Countries where cigarette smoking is only now becoming widespread can expect enormous increase in lung cancer during the 1990"s or early in the next century, 8 prompt effective action is taken against the habit—indeed, such increase are already plainly evident in parts of the world. There are reasons why the preventions of lung cancer is of such overwhelming importance. First, the disease is extremely common, causing more deaths than any other types of cancer now 9 ; secondly, it is generally incurable; thirdly, effective, practicable measures to reduce its incidence are already reliably known; and finally, reducing tobacco consumption will also have a substantial 10 on many other diseases.

单选题(略){{B}}Part Ⅱ Vocabulary{{/B}}There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Passage one: Questions 21-25 are based on the following passage. This year the combined advertising revenues of Google and Yahoo ! will rival the combined primetime ad revenues of America's three big television networks, ABC,CBS and NBC predicts Advertising Age. It will, says the trade magazine, represent a "watershed moment" in the evolution of the internet as an advertising medium. A 30-second prime-time TV ad was once considered the most effective--and the most expensive--form of advertising. But that was before the internet got going. And this week online advertising made another leap forward. This latest innovation comes from Google, which has begun testing a new auction-based service for display advertising. Both Google and Yahoo! make most of their money from advertising. Auctioning keyword search-terms,which deliver sponsored links to advertisers' websites, has proved to be particularly lucrative. And advertisers like paid-search because, unlike TV, they only pay for results: they are charged when someone clicks on one of their links. Both Google and Yahoo! along with search-site rivals like Microsoft's MSN and Ask Jeeves, are developing much broader ranges of marketing services. Google, for instance, already provides a service called AdSense. It works rather like an advertising agency, automatically placing sponsored links and other ads on third-party websites. Google then splits the revenue with the owners of those websites, who can range from multinationals to individuals publishing blogs, as online journals are known. Google's new service extends AdSense in three ways. Instead of Google's software analyzing third-party websites to determine from their content what relevant ads to place on them, advertisement will instead be able to select the specific sites where they want their ads to appear. This provides both more flexibility and control, says Patrick Keane, Google's head of sales strategy. The second change involves pricing. Potential internet advertisers must bid for their ad to appear on a "cost-per-thousand" (known as CPM) basis. This is similar to TV commercials, where advertisers pay according to the number of people who are supposed to see the ad. But the Google system delivers a twist: CPM bids will also have to compete against rival bids for the same ad space from those wanting to pay on a "costper-click" basis, the way search terms are presently, sold. Click-through marketing tends to be aimed at people who already know they want to buy something and are searching for product and price information, whereas display advertising is more often used to persuade people to buy things in the first instance. The third change is that Google will now offer animated ads--but nothing too flashy or annoying, insists Mr. Keane. Such ads are likely to be more appealing to some the big-brand advertisers. Spurred on by the spread of faster broadband connections, such companies are becoming increasingly interested in so-called "rich-media" ads. like animation and video.
