[单项选择]Why save endangered species For the general public, endangered species appear to be little more than biological oddities. A very different perception is gained from considering the issue of extinction in a wider context. The important point is that many major social advances have been made on the basis of life forms whose worth would never have been perceived in advance. Consider the impact of rubber-producing plants on contemporary life and industry: approximately two-thirds of the world’s rubber supply comes from rubberproducing plants and is made into objects as diverse as rubber washers and rubber boots.
The author’s point is made chiefly by
A. acknowledging the validity of two opposing points of view.
B. appealing to the emotions of the audience rather than to their intellects.
C. suggesting a useful perspective for viewing the question raised at the beginning of the passage.
D. trying to discredit the view of an opponent without presenting an alternative hypothesis.
E. (E) generalizing from similar to dissimilar cases.

[简答题]Passage 2 Endangered Species Endangered species are plants and animals that are in immediate danger of extinction. Extinction is actually a normal process in the course of evolution. Since the formation of the earth, many more species have become extinct than those exist today. These species slowly disappeared because of changes of climate and their failure to adapt to such conditions as competition and predation (捕食). Since the 1600s, however, the process of extinction has greatly accelerated as a result of both human population growth and technological encroachment (侵犯) on natural ecology systems. Today the majority of the world’s environments are changing faster than the ability of most species to adapt to such changes through natural selection. Species become extinct or endangered for a number of reasons, but the primary cause is the destruction of natural habitats (栖息地). Drainage of wetlands (沼泽地), cutting and clearing of forests, growth of cities, and highway
A. A．Human beings are not aware of the importance of preserving endangered species.
B．Some endangered species have already reached the end of their life span in evolution.
C．The development of human society has greatly affected natural ecology systems.
D．The world’s climate has changed so greatly that most species cannot survive.

[单项选择]What is less well understood by the general public is that- there have been a number of trends which have further contributed to the diminishment of excavation as an activity. As Bahn puts it "there have been two major trends over time: first, excavation has become far slower and more painstaking .... The work is incredibly meticulous... Secondly, we can learn far more from what we have." The conclusions to be drawn from this would appear to be contradictory.
As technology improves we are able to undertake a wide variety of analysis from microscopic, radio carbon dating or even DNA ’samples. The ability to determine more, from fewer samples again suggests that less excavation is required. Moreover, more often than not the balance of effort now rests with the specialist analysis such as pollen experts and dating analysis rather than the excavators. So, again some of the requirements for extensive excavation have diminished through the advancement of other analytical techniques and
A. The apply of radio carbon dating.
B. More acquisition of artifacts.
C. Emergence of processual archaeology.
D. Development of surface survey technique.
