However, you are to choose the best answer, that is, the response that most accurately and completely answers the question, and blacken the corresponding space on your answer sheet.The extent of a nations power over its coastal ecosystems and the natural resources in its coastal waters has bee
3、n defined by two international law doctrines: freedom of the seas and adjacent state sovereignty. Until the mid-twentieth century, most nations favored application of broad open-seas freedoms and limited sovereign rights over coastal waters. A nation had the right to include within its territorial d
4、ominion only a very narrow band of coastal waters (generally extending three miles from the shoreline), within which it had the authority but not the responsibility, to regulate all activities. But, because this area of territorial dominion was so limited, most nations did not establish rules for ma
5、nagement or protection of their territorial waters.Regardless of whether or not nations enforced regulations in their territorial waters, large ocean areas remained free of controls or restrictions. The citizens of all nations had the right to use these unrestricted ocean areas for any innocent purp
6、ose, including navigation and fishing. Except for controls over its own citizens, no nation had the responsibility, let alone the unilateral authority, to control such activities in international waters. And, since there were few standards of conduct that applied on the “open seas”, there were few j
7、urisdictional conflicts between nations.The lack of standards is traceable to popular perceptions held before the middle of this century. By and large, marine pollution was not perceived as a significant problem, in part because the adverse effect of coastal activities on ocean ecosystems was not wi
8、dely recognized, and pollution caused by human activities was generally believed to be limited to that caused by navigation. Moreover, the freedom to fish, or overfish, was an essential element of the traditional legal doctrine of freedom of the seas that no maritime country wished to see limited. A
9、nd finally, the technology that later allowed exploitation of other ocean resources, such as oil, did not yet exist.To date, controlling pollution and regulating ocean resources have still not been comprehensively addressed by law, but international lawestablished through the customs and practices o
10、f nationsdoes not preclude such efforts. And two recent developments may actually lead to future international rules providing for ecosystem management. First, the establishment of extensive fishery zones extending territorial authority as far as 200 miles out from a countrys coast, has provided the
11、 opportunity for nations individually to manage larger ecosystems. This opportunity, combined with national self-interest in maintaining fish populations, could lead nations to reevaluate policies for management of their fisheries and to address the problem of pollution in territorial waters. Second
12、 the international community is beginning to understand the importance of preserving the resources and ecology of international waters and to show signs of accepting responsibility for doing so. As an international consensus regarding the need for comprehensive management of ocean resources develop
13、s, it will become more likely that international standards and policies for broader regulation of human activities that affect ocean ecosystems will be adopted and implemented.1. According to the passage, until the mid-twentieth century there were few jurisdictional disputes over international water

15、waters was shared equally among all nations2. According to the international law doctrines applicable before the mid-twentieth century, if commercial activity within a particular nations territorial waters threatened all marine life in those waters, the nation would have been(A) formally censured by
16、 an international organization for not properly regulating marine activities(B) called upon by other nations to establish rules to protect its territorial waters(C) able but not required to place legal limits on such commercial activities(D) allowed to resolve the problem at it own discretion provid
17、ing it could contain the threat to its own territorial waters(E) permitted to hold the commercial offenders liable only if they were citizens of that particular nation3. The author suggests that, before the mid-twentieth century, most nations actions with respect to territorial and international wat
18、ers indicated that(A) managing ecosystems in either territorial or international waters was given low priority(B) unlimited resources in international waters resulted in little interest in territorial waters(C) nations considered it their responsibility to protect territorial but not international w
19、aters(D) a nations authority over its citizenry ended at territorial lines(E) although nations could extend their territorial dominion beyond three miles from their shoreline, most chose not to do so4. The author cites which one of the following as an effect of the extension of territorial waters be
20、yond the three-mile limit?(A) increased political pressure on individual nations to establish comprehensive laws regulating ocean resources(B) a greater number of jurisdictional disputes among nations over the regulation of fishing on the open seas(C) the opportunity for some nations to manage large
21、 ocean ecosystems(D) a new awareness of the need to minimize pollution caused by navigation(E) a political incentive for smaller nations to solve the problems of pollution in their coastal waters5. According to the passage, before the middle of the twentieth century, nations failed to establish rule

25、oblem参考答案：1-6 BCACCDThe human species came into being at the time of the greatest biological diversity in the history of the Earth. Today, as human populations expand and alter the natural environment, they are reducing biological diversity to its lowest level since the end of the Mesozoic era, 65 m
26、illion years ago. The ultimate consequences of this biological collision are beyond calculation, but they are certain to be harmful. That, in essence, is the biodiversity crisis.The history of global diversity can be summarized as follows: after the initial flowering of multicellular animals, there
27、was a swift rise in the number of species in early Paleozoic times (between 600 and 430 million years ago), then plateaulike stagnation for the remaining 200 million years of the Paleozoic era, and finally a slow but steady climb through the Mesozoic and Cenozoic eras to diversitys all-time high. Th
28、is history suggests that biological diversity was hard won and a long time in coming. Furthermore, this pattern of increase was set back by five massive extinction episodes. The most recent of these, during the Cretaceous period, is by far the most famous, because it ended the age of the dinosaurs,
29、conferred hegemony on the mammals, and ultimately made possible the ascendancy of the human species. But the cretaceous crisis was minor compared with the Permian extinctions 240 million years ago, during which between 77 and 96 percent of marine animal species perished. It took 5 million years, wel
30、l into Mesozoic times, for species diversity to begin a significant recovery.Within the past 10,000 years biological diversity has entered a wholly new era. Human activity has had a devastating effect on species diversity, and the rate of human-induced extinctions is accelerating. Half of the bird s
31、pecies of Polynesia have been eliminated through hunting and the destruction of native forests. Hundreds of fish species endemic to Lake Victoria are now threatened with extinction following the careless introduction of one species of fish, the Nile perch. The list of such biogeographic disasters is
32、 extensive.Because every species is unique and irreplaceable, the loss of biodiversity is the most profound process of environmental change. Its consequences are also the least predictable because the value of Earths biota (the fauna and flora collectively) remains largely unstudied and unappreciate
33、d; unlike material and cultural wealth, which we understand because they are the substance of our everyday lives, biological wealth is usually taken for granted. This is a serious strategic error, one that will be increasingly regretted as time passes. The biota is not only part of a countrys herita
34、ge, the product of millions of years of evolution centered on that place; it is also a potential source for immense untapped material wealth in the form of food, medicine, and other commercially important substance.7. Which one of the following best expresses the main idea of the passage?(A) The red

The author suggests which one of the following about the Cretaceous crisis?(A) It was the second most devastating extinction episode in history.(B) It was the mo
41、st devastating extinction episode up until that time.(C) It was less devastating to species diversity than is the current biodiversity crisis.(D) The rate of extinction among marine animal species as a result of the crisis did not approach 77 percent.(E) The dinosaurs comprised the great majority of
42、 species that perished during the crisis.10. The author mentions the Nile perch in order to provide an example of(A) a species that has become extinct through human activity(B) the typical lack of foresight that has led to biogeographic disaster(C) a marine animal species that survived the Permian e

All of the following are explicitly mentioned in the passage as contributing to the extinction of species EXCEPT(A) hunting(B) pollution(C) def
44、orestation(D) the growth of human populations(E) human-engineered changes in the environment12. The passage suggests which one of the following about material and cultural wealth?(A) Because we can readily assess the value of material and cultural wealth, we tend not to take them for granted.(B) Jus
45、t as the biota is a source of potential material wealth, it is an untapped source of cultural wealth as well.(C) Some degree of material and cultural wealth may have to be sacrificed if we are to protect our biological heritage.(D) Material and cultural wealth are of less value than biological wealt
46、h because they have evolved over a shorter period of time.(E) Material wealth and biological wealth are interdependent in a way that material wealth and cultural wealth are not.13. The author would be most likely to agree with which one of the following statements about the consequences of the biodi
47、versity crisis?(A) The loss of species diversity will have as immediate an impact on the material of nations as on their biological wealth.(B) The crisis will likely end the hegemony of the human race and bring about the ascendancy of another species.(C) The effects of the loss of species diversity
48、will be dire, but we cannot yet tell how dire.(D) It is more fruitful to discuss the consequences of the crisis in terms of the potential loss to humanity than in strictly biological loss to humanity than in strictly biological terms.(E) The consequences of the crisis can be minimized, but the pace of extinctions can not be reversed.参考答案：7-13 EEDBBACWomens participation in the revolutionary events in France between 1789 and 1795 has only recently been given nuanced treatment.
