In almost all places in New York State where ducky salamanders used to live, suburban development has cleared uplands and put down asphalt. As a result, rainwater now runs directly into streams, causing increased flow that slows the accumulation of organic sediments. Therefore, it is probably the increased flow caused by suburban development that is responsible for the dusky salamanders virtual disappearance from New York State. 1. Which of the following, if true, most strongly supports the argument? A. Since 1980 the suburban population of New York State has grown ten times faster than its urban 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！the 1920s Harlem “stride” style, and an important blues and jazz composer. In addition, however, Johnson was an innovator in classical music, composing symphonic music that incorporated American, and especially African American, traditions. Such a blend of musical elements was not entirely new: by 1924 both Milhaud and Gershwin had composed classical works that incorporated elements of jazz. Johnson, a serious musician more experienced than most classical composers with jazz, blues, spirituals, and popular music, was particularly suited to expand Milhauds and Gershwins experiments. In 1927 he completed his first large-scale work, the blues- and jazz-inspired Yamekraw, which included borrowings from spirituals and Johnsons own popular songs. Yamekraw, premiered successfully in Carnegie Hall, was major achievement for Johnson, becoming his most frequently performed extended work. It demonstrated vividly the possibility of assimilating contemporary popular music into the symphonic tradition. 1.

This increase is partially accounted for by the fact that many urban households had previously sent their clothes to professional laundries. But the average amount of time spent washing clothes also increased for rural households with no access to professional laundries. 1. Which of the following, if true, most helps to explain why the time spent washing clothes increased in rural areas? 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！ A. People with access to an electric washing machine typically wore their clothes many fewer times before washing them than did people without access to electric washing machines. B. Households that had sent their clothes to professional laundries before 1925 were more likely than other households to purchase an electric washing machine when they became available. C. People living in urban households that had previously sent their clothes to professional laundries typically owned more clothes than did people living in rural households. D. The earliest electric washing machines required the user to spend much more time beside the machine than do modern electric washing machines. E. In the 1920s and 1930s the proportion of rural households with electricity was smaller than the proportion of urban households with electricity. 2021GRE 阅读真题解析之 PP2-3 Passage2 PP2-3 Passage 2 In 1996, scientists caused an experimental flood 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！of the Colorado River by releasing water from Glen Canyon Dam above the Grand Canyon. Because an unintentional flood in 1983 had reduced the rivers introduced population of nonnative trout, biologists were concerned that the experimental flood would wash many fish, native and nonnative, downstream. To find out, biologists placed nets in the river. The nets captured a few more trout than they would have without the flood but did not show substantial flushing of native fish, whose ancestors had, after all, survived many larger natural floods. The biologists surmised that the native species (and most of the trout) must have quickly retreated to protected areas along the riverbank. 1. Which of the following, if true, would make the information presented in the passage compatible with the experimental flood s in fact having caused substantial flushing of native fish? A. Many of the native fish are too small to have been captured by the nets. B. There had been and increase from normal levels in the native fish population prior to the flood. 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！ C. The native fish in the Colorado are much stronger swimmers than taxonomically similar fish in other rivers in the region. D. The unintentional flood of 1983 had not affected the rivers trout population as much as was originally thought. E. The experimental flood raised the water level much less than a typical natural flood would have. 2. According to the passage, which of the flowing is true of the Colorado River flood of 1983? A. The flood had a negative effect on the rivers trout population. B. There was substantial flushing of the rivers native fish population during the flood. C. Unlike the 1996 flood, it was not deliberately caused for scientific research purposes. 2021GRE 阅读真题解析之 PP2-3 Passage1 PP2-3 Passage 1 Some universities have created environmental studies programs that can be marketed to prospective students but that suffer from too little administrative 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！support, limited faculty resources, and a lack of careful deliberation over the hard choices. In the short term, this institutional strategy can pay rich dividends: at minimal expense a university can lay claim to an environmental studies program and attract new students or accommodate the interest of existing ones, perhaps with the full intention of bringing additional resources to bear in later years. As the number of students in these skeleton programs grows, however, the flimsy administrative and curricular scaffolding begins to buckle, leading to an anything-goes strategy that degenerates into curricular incoherence. 1. The passage implies which of the following about the relationship between students and environmental studies programs? A. Students new to a university are more likely to be aware of environmental studies programs than existing students are. B. Students prefer curricular incoherence in environmental studies programs to rigid administrative decision making. 欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！ C. The curricular flexibility of an environmental studies program is an attraction for new students. D. If a university offers an environmental studies program, then students will enroll in it. E. New students will guarantee the success of an environmental studies program. 2. The passage suggests which of the following about “skeleton programs” in environmental studies? A. They may fail to attract prospective students. B. At some point they are likely to collapse into curricular confusion. C. They may par rich dividends in short term. 2021GRE 阅读真题解析
