30、by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. 51 Americans had always been preoccupied with reforming their society: “ with making it over“ , and between the 1890s and the First World War,
31、 the reform spirit intensified. More and more people tried to address the problem of their time directly, to impose order on a confusing world, and, especially, to create a conflict-free society. Their efforts helped what can be called the progressive era. The urge for reform had many sources. Indus
32、trialization had brought unprecedented productivity, awesome technology, and plenty of consumer goods. But it had also included labor struggle, waste of natural resources, and abuse of corporate power. Rapidly growing cities facilitated the accumulation and distribution of goods, services, and cultu
33、ral amenities(礼节 )but also magnified problems of poverty, disease, crime, and political corruption. Massive inflows of immigrants and the rise of a new class of managers and professionals shook the foundations of old social classes. And the depression that crippled the nation in the 1890s made many
34、leading citizens realize what working people had known for some time: the central promise of American life was not being kept: equality of opportunity whether economic, political, or social was a myth. Progressives tried to resolve these problems by organizing ideas and actions around three basic th
35、emes. First, they sought to end abuses of power. Second, Progressives aimed to replace corrupt power with the power of reformed institutions such as schools, charities, medical clinics, and the family. Third, Progressives wanted to apply principles of science and efficiency on a nationwide scale to
36、all economic, social, and political institutions, to minimize social and economic disorder and to establish cooperation, especially between business and government, that would end wasteful competition and labor conflict. Befitting their name, Progressives had strong faith in the ability of humankind
37、 to create a better world. More than ever before, Americans looked to government as an agent of the people that could and should intervene in social and economic relations to protect the common good and substitute public interest for self-interest. 52 According to the second paragraph, which of the
38、following is NOT the source of urge for reform? （ A） The outcome brought by industrialization. （ B） Social problems magnified by growing cities. （ C） Freedom and democracy of American society. （ D） The shaking of foundations of old social classes. 53 Progressives mentioned the following measures to
39、end wasteful competition and labor conflict EXCEPT_. （ A） application of scientific and efficient principles （ B） minimizing social and economic disorder （ C） replacement of corrupt power （ D） cooperation between business and government 53 More than 2 million films languish in vaults(地窖 )around the
40、world, some of them so badly damaged they can no longer be screened. If nothing is done, they could disappear for good, like half the films made in the US before 1950. But research at the university of La Rochelle in France and Monash University in Clayton, Victoria, promises an automated technique
41、to restore these old films to their former glory. Films can be cleaned chemically or by using ultrasound. But this is time-consuming and expensive, and chemicals can also damage the original. Another approach is to digitize the film and then clean up the digital version frame by a frame a daunting j
42、ob. When Disney cleaned up Snow White for release on DVD, for instance, graphic artists worked in shifts on 40 computers day and night for 18 weeks. These computer-aided techniques remain very expensive, says Samin Boukier, who started work on an automated system in La Rochelle. Only an automated sy
43、stem can hope to salvage the archive(档案文件 )of deteriorating films. Once a film has been scanned in, the first stage of the process is to correct flicker caused by the film slipping the result of damage to its perforations. The system works out if two frames are usually close to each other or far apa
44、rt, and corrects any anomalies. Dust spots usually occur only on single frames, so the system looks for small stains that are visible on one frame and absent on its neighbors. The software repairs the image by sampling the unspoiled area of the image on the adjacent frames and replacing the dust spo
45、t with an average of the sampled pixels(像素 ). Detecting scratches is more complicated because they may run over several frames and can be confused with vertical lines that are part of the film. But a telltale pattern often gives them away: Scratches are normally caused by the mechanical parts of a p
46、rojector rubbing on the film, so they tend to repeat at regular intervals. The system looks for a periodic pattern of this type from frame to frame, predicting when it should occur in the subsequent frames. Having identified the scratch and its duration, the software then repairs the damage by takin
47、g pixels from undamaged frames before and after the scratch. This smoothing effect avoids any sharp edges in the restored image. “When detecting dust particles,“ says Boukir, “95 percent accuracy is acceptable. But with line scratches it has to be better. The removal of significant scene details wou
48、ld have disastrous consequential effects on the resulting restored movie,“ she explains. Because of this, some level of human intervention will be needed. Once restored, the digitized films can be viewed by future generations without risking more damage to the original by running it through a projector. “ Film has a hundred-year history, but the knowledge of how to store it properly is only 15 years old,“ says Godfrey Pye of Sunset Digital, a Hollywood-based company that specializes in cleaning up old movies. 54 The writer cites the example of Disney in Paragraph 2 in order to show th
