●例子：例子必出題。文章有論點(diǎn)-論據(jù)-論證，例子是論證，用來支持論點(diǎn)，所以簡而言之，例子本身不重要，但前后論點(diǎn)極其重要。
例子開始的標(biāo)志：for example，后面跟著大寫、時(shí)間、年代，依然是舉例內(nèi)容。
例子含義的標(biāo)志：show, tell, prove, demonstrate, find, clearly

[Page72]
In the United States, the need to protect plant and animal species has become a highly controversial and sharply political issue since the passage of the Endangered Species Act in 1973. The act, designed to protect species' living areas, and policies that preserve land and forests compete with economic interests. In the 1990's, for example, the woodcutters in the Western United States were challenged legally in their attempt to cut trees for timber in the Cascade Mountains. The challenge was mounted to protect the endangered spotted owl(貓頭鷹), whose remaining population occupies these forests and requires the intact, ancient forest for survival. The problematic situation set the interests of environmentalists against those of corporations and of individuals who stood to lose jobs. After months of debate and legal battles, the fate of the woodcutters-and the owls-was still undecided in mid-1992.

3. problematic懸而未決的
Similar tensions exist between the developed and the developing nations. Many people in industrialized nations, for example, believe that developing nations in tropical regions should do more to protect their rain forests and other natural areas. But the developing countries may be impoverished (使窮困), with populations growing so rapidly that using the land is a means to temporarily avoid worsening poverty and starvation.

3. But轉(zhuǎn)折是重點(diǎn)
Many of the changes to Earth that concern scientists have the potential to rob the planet of its biological richness. The destruction of Earth's ozone layer (臭氧層), for example, could contribute to the general process of impoverishment by allowing ultra-violet rays to harm plants and animals. And global warming could wipe out species unable to quickly adapt to changing climates. Clearly, protecting will come only through coordinated international efforts to control human population, stabilize the composition of the atmosphere, and preserve intact Earth's complex web life.
36.Why does the author say that the protection of endangered species is a highly controversial
issue?
A) Because people can't agree as to what species to protect.
B) Because it is difficult to find an effective way to protect such species.
C) Because it affects the interests of certain groups of people.
D) Because it is a major problem involving a series of legal procedures.

We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫學(xué)家)Mark Laudenslger, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could mot. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.

Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don't develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists' suspicions that the experience or perception of helplessness is one of the most harmful factors in depression.
