7(E)
首段介绍human是带来biodiversity crisis的因素
次段通过global diversity陈述diversity的建立不容易，隐含意思为：维持diversity很重要，要力争避免crisis
第三段列举人为因素
第末段分析造成“人为因素”的原因

通过对文章四个段落组织架构的分析，可以看出作者的态度
“The current decline in species diversity is human-induced tragedy of incalculable proportions that has potentially grave consequences for the human species.”

8(E)
关键词为“analogous to the history of global diversity”中的analogous，这需要我们找出global diversity自己的特点，然后才能类比
根据原文
“after the initial flowering of multicellular animals, there 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 diversity’s all-time high.”
中的红色关键词，不难看出global diversity是“涨，保持，涨”的状态，这与选项(E)的描述相符合
“The variety of styles stocked by a shoe store increases rapidly after the store opens, holds constant for many months, and then gradually creeps upward.”

9(D)
根据“the Cretaceous crisis”定位原文
“The most recent of these<five massive extinction episodes>, during the Cretaceous period, is by far the most famous, because it ended the age of the dinosaurs, 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”
这个比较明显地告诉我们，cretaceous crisis<77%
因此，“The rate of extinction among marine animal species as a result of the crisis did not approach 77 percent.”

注意到BUT在出题中的应用，阅读遇到BUT时要标记，要留心！

10(B)
根据“the Nile perch”定位原文
“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 extensive.”
再对应选项(B)
“the typical lack of foresight that has led to biogeographic disaster”二者表意相同，证明Nile perch的引入是错误之举

11(B)
根据“contributing to the extinction of species”，查找每一个选项在原文中的对应位置
(A)(C)--“Half of the bird species of Polynesia have been eliminated through hunting and the destruction of native forests.”
(D)(E)—“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 million years ago”
选项(B)并没有提到，某些同学可能会将自己的主观看法带进这道题，这只是中了ETS的圈套。

12(A)
根据“material and cultural wealth”定位原文
“Its consequences are also the least predictable because the value of Earth’s biota (the fauna and flora collectively) remains largely unstudied and unappreciated; unlike material and cultural wealth, which we understand because they are the substance of our everyday lives,
biological wealth is usually taken for granted”
通过unlike的对比，material and cultural wealth受到重视(与taken for granted相反)是因为“they are the substance of our everyday lives”，因此
“Because we can readily assess the value of material and cultural wealth, we tend not to take them for granted”

13(C)
根据“the consequences of the biodiversity crisis”定位原文
“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 Earth’s biota (the fauna and flora collectively) remains largely unstudied and unappreciated… This is a serious strategic error, one that will be increasingly regretted as time passes. The biota is not only part of a country’s heritage, 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”
字体表明dire，字体是对dire对立面的陈述，反证dire，字体解释cannot tell的原因，因此，
“The effects of the loss of species diversity will be dire, but we cannot yet tell how dire”
