第8题：
问答题Despite the basic biological, chemical, and physical similarities found in all living things, a diversity of life exists not only among and between species but also within every natural population. The phenomenon of diversity has had a long history of study because so many of the variations that exist in nature are visible to the eye. 1) It has been suggested that sexual reproduction became the dominant type of reproduction among organisms because of its inherent advantage of variability, which is the mechanism that enables a species to adjust to changing conditions.New variations are potentially present in genetic differences, but how preponderant a variation becomes in a gene pool depends upon the number of offspring the mutants or variants produce (differential reproduction). 2)It is possible for a genetic novelty (new variation) to spread in time to all members of a population, especially if the novelty enhances the population’s chances for survival in the environment in which it exists.Thus, when a species is introduced into a new habitat, it either adapts to the change by natural selection or by some other evolutionary mechanism or else it eventually dies off. Because each new habitat means new adaptations, habitat changes have been responsible for the millions of different kinds of species and for the heterogeneity within each species. The total number of animal and plant species is estimated at between 2,000,000 and 4,500,000; authoritative estimates of the number of extinct species range from 15,000,000 up to 16,000,000,000. 3)Although the use of classification as a means of producing some kind of order out of this staggering number of different types of organisms appears as early as the book of Genesis—with references to cattle, beasts, fowl, creeping things, trees, etc.—the first scientific attempt at classification is attributed to the Greek philosopher Aristotle, who tried to establish a system that would indicate the relationship of all things to each other.He arranged everything along a scale, or “ladder of nature”, with nonliving things at the bottom; plants were placed below animals, and man was at the top. 4)Other schemes that have been used for grouping species include large anatomical similarities, such as wings or fins, which indicate a natural relationship, and also similarities in reproductive structures. 5)At the present time taxonomy is based on two major assumptions: one is that similar body construction can be used as a criterion for a classification grouping; the other is that, in addition to structural similarities, evolutionary and molecular relationships between organisms can be used as a means for determining classification.正确答案：
(1)【答案】有人曾经提出:有性繁殖在有机生命体的繁殖方式中占支配地位,其原因在于有性繁殖所固有的变异性方面的优势。变异性是一种机制,能使物种自我调节以适应条件的变化。
【解析】该句需要注意的是It has been suggested...不能直接翻译成“它被建议…”,it指代的该句中that之后的内容,此处it只是起到形式主语的作用,因此应根据汉语多主动句的特点将其译为:有人曾经提出…。
(2)【答案】某种遗传变异(新变异)及时扩散到一个生物群体的所有成员,这是可能的。尤其当这种变异能提高该群体在其生存环境中的存活机会时,可能性更大。
【解析】本句需要注意的是对It is possible...的翻译,由于真正的主语是possible之后的内容,因此翻译时应译为:…是由可能的。此外,enhance的宾语为chances(机会),因此应取其“提高”的意思。
(3)【答案】虽然早在《物种起源》那本书中就使用分类方法把为数众多的不同种类的生物排列出了一个次序,书中提到的生物包括:家养牲畜、野兽、禽类、爬行动物、树木等。不过,真正从科学上首次尝试对物种分类还应归于希腊哲学家亚里士多德。他曾试图建立一个体系,来表明世界万物彼此之间的关系。
【解析】本句中破折号之间的内容为解释说明,翻译时可将其独立成句,并添加主语,即:书中提到的生物包括:家养牲畜、野兽、禽类、爬行动物、树木等。
(4)【答案】曾经用来进行物种分类的其他方法还有:根据解剖结构上存在的重大相似性分类,比如翅膀或鳍,这种相似性显示的是自然属性的关系;还可以根据繁殖系统结构的相似性分类。
【解析】anatomical意为“结构上的,解剖的”,fin指“鱼鳍,鳍状物”,该句中which引导的定语从句是对anatomical similarities的修饰。
(5)【答案】目前,生物分类学基于两大思路:一个是可以用生物体结构的相似性作为物种分类的依据;另一个是,除了结构的相似性以外,还可以把生物在进化以及分子方面的关联作为决定分类的依据。
【解析】taxonomy意为“(生物)分类学”,注意该句中被动形式“taxonomy is based on”与汉语主动形式“生物分类学基于…”之间的转换。解析： 暂无解析 -

第12题：
问答题Practice 6 Yet just as we are beginning to recognize the tremendous diversity of life in these areas, along with the potential benefits newly found species may hold for human society in the form of potential food products and new medicines, they are at risk of being lost forever. With enhanced ability both to identify where these species-rich areas are located and to trawl in deeper water than before, commercial fishing vessels are now beginning to reach down with nets the size of football fields, catching everything in their path while simultaneously crushing fragile corals and breaking up the delicate structure of reefs and seamounts that provide critical habitat to the countless species of fish and other marine life that inhabit the deep ocean floor. Because deep sea bottom trawling is a recent phenomenon, the damage that has been done is still limited. If steps are taken quickly to prevent this kind of destructive activity from occurring on the high seas, the benefits both to the marine environment and to future generations are incalculable. And they far outweigh the short-term costs to the fishing industry.正确答案： 【参考译文】
当我们现在刚刚开始认识这些地区极其丰富的生物多样性,并发现这些新物种可能为人类社会带来好处时——如新食品和新药品,这些地区却面临着永远消失的危险。由于确定物种丰富地区的能路增强,由于拖网捕涝能到达比过去更深的区域,商业渔船可把足球场大小的拖网撒入海中,碰上什么捕捞什么,同时损坏了脆弱的珊瑚,破坏礁石和海底山的脆弱结构,而正是这些东西为生活在深海海底的无数鱼类和其它海洋生物提供了赖以生存的场所。
因为深海海底拖网捕捞是最近才出现的一种现象,它所造成的损害还是有限的。如能赶紧采取措施防止这些在公海上的破坏活动,它为海洋环境和子孙后代带来的好处将是无法估量的。这些好处将远远超过渔业短期内需承担的花费。解析： 暂无解析 -
第13题：
The loss of biological diversity has become most spectacularly noticeable in extinction or decline of populations of large and well-known animals.Many animal species have become extinct since the 1700’s, among them the California grizzly bear, the dodo, and the passenger pigeon.Hundreds of other animal species are threatened.In North America, endangered species include the black-footed ferret, the California condor, the desert tortoise, and the whooping crane.
Most species in danger of extinction anywhere in the world are suffering from the intrusion (侵入) of human beings.The Asian elephant, for example, has become an endangered species due to the expansion of the human population throughout its range in southern Asia.In Africa, the African elephants are being killed off for their tusks.Monkeys and other primates throughout the world are threatened by hunting, capture for medical use, and the destruction of their habitats.And the rhinoceroses, lions, and other large mammals of the African savanna (grassy plains with scattered trees) compete for land and life with some of the most rapidly growing human populations in the world.
The loss of biological diversity is most severe, however, in the tropical rain forests.The forests of the tropics are particularly vulnerable to disturbance because the soils have a low capacity for retaining nutrients.Most of the forests’ nutrient elements are held in the tissues of plants.When loggers and farmers destroy existing plant cover, the nutrients are washed from the land into streams, and the land itself becomes less able to support life.Destruction of these forests destroys the habitat of hundreds, sometimes thousands, of species from such creatures as the howler monkey and indigo macaw, to less visible species of plants, insects, and microbes, many of which are not yet known to science.
1.The author points out that species extinction ().
A.is most noticeable in North America
B.is mainly taking place among large animals
C.quickened with industrialization of the society
D.never took place before the 1700’s
2.Which of the following is NOT mentioned with regard to human intrusion?
A.Elephants are killed off for their tusks
B.Some primates are hunted for medical use
C.Growing human population results in the competition for land and life among animals
D.Men live increasingly on animals as their source of food.
3.The chief cause of the gradual disappearance of biological diversity is ().
A.human cruelty
B.human interference
C.the increase of human population
D.the disappearance of the forests
4.In tropical forests，().
A.animals live a hard life due to competition
B.a lot of species die out for lack of food
C.rains constitute the major threat to species
D.a greater number of animals are yet to be known
5.It can be inferred that species extinction ().
A.proceeds of a faster rate than noticeable
B.is the worst among well-known animals
C.is the most severe in Africa
D.is chiefly due to competition among species

Ants as a Barometer of Ecological Change
At picnics,ants are pests.But they have their uses.In industries such as mining,farming and forestry,they can help gauge the health of the environment by just crawling around and being antsy.
It has been recognized for decades that ant—which are highly sensitive to ecological change—can provide a near-perfect barometer of the state of an ecosystem.Only certain species, for instance,will continue to thrive at a forest site that has been cleared of trees._______(46) And still others will move in and take up residence.
By looking at which species populate a deforested area,scientists can determine how “stressed”the land is._______(47)Ants are used simply because they are so common and comprise so many species.
Where mine sites are being restored,for example,some ant species will recolonize the stripped land more quickly than others._______(48)Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recov-ery of land that it is replanting near its German Creek mine in Queensland.
Ant surveys also have been used with mine-site recovery projects in Africa and Brazil,where warm climates encourage dense and diverse ant populations.“We found it worked extremely well there,”says Jonathan Majer,a professor of environmental biology.Yet the surveys are perfectly suited to climates throughout Asia,he says,because ants are so common throughout the region. As Majer puts it:“That's the great thing about ants.”
Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting._______ (49)
Why not?Because many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey.The cost stems,also,from the scarcity of ant specialists. ______(50)_______(46)
A: This allowed scientists to gauge the pace and progress of the ecological recovery.
B: Yet in other businesses,such as farming and property development,ant surveys aren't used widely.
C: Employing those people are expensive.
D: They do this by sorting the ants,counting their numbers and comparing the results with those of earlier surveys.
E: The evolution of ant species may have a strong impact on our ecosystem.
F: Others will die out for lack of food.答案：F解析：空前一句“Only certain species , for instance , will continue to thrive at a forest site that has been cleared of trees”讲到某些特定物种在被砍光树木的森林里还能够继续存活，空后一句“still others will move in and take up residence”讲到自然会有其他生物迁入并定居下来，F项“其他种类将会因为缺乏食物而灭绝”与上下文联系紧密，符合语境。
空后一句“scientists can determine how ‘stressed ' the land is”讲到科学家们之所以利用蚂蚁是因为它们很常见而且种类繁多，在此之前应该说明怎么样利用蚂蚁,D项 “科学家们的观察是通过对蚂蚁的分类、数目的确定以及与前期调查结果的对比分析来进行的”符合语境。
空前一句讲到在一些矿井地带的recolonize（复原）过程中，会有一些蚂蚁的物种比其他物种更快地重新在植被破坏的土地上安家，A项“这样可以帮助科学家们测定生态恢复的速度和进程”与上文联系紧密，并且A项中的“the ecological recovery”与本段首句中的“are being restored”相照应，故选A。
空前一句“that governments worldwide accept their results when assessing the environ-mental impact of mining and tree harvesting”讲到世界各国政府都承认了通过蚂蚁而得出的关于估测采矿和伐林对环境带来的影响的结果，而第七段第一句则问道：为什么不用呢？B项“然而在另外一些行业中，比如农业和房地产开发业，用蚂蚁调查的方法并没有被广泛地采用”与下文联系紧密，起承上启下作用，符合语境。
空前一句“many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey”讲到很多国家不能付出高额的费用，研究蚂蚁的专家稀少，故C项“雇佣他们花费巨大”与上文联系紧密，符合语境。 -

问答题The Importance of being Interested 1) Now I have recalled these beginnings of the careers of Franklin, Darwin and Mozart because they strikingly illustrate a profound psychological truth the significance of which can scarcely be overestimated. 2) It is fl truth, to be sure, that has long been partially recognized. 3)But its full meaning has not been--and could not be—appreciated until quite recently. 4)Only within the past few years has scientific research effected various discoveries which make its complete recognition possible and of supreme importance—of such importance that practical application of the principles involved would make for an immediate and stupendous increase in human happiness, efficiency, and welfare. 5)Stated briefly, the truth in question is that success in life, meaning thereby t he accomplishment of results of real value to the individual and to society, depends chiefly on sustained endeavor springing out of a deep and ardent interest in the tasks of one's chosen occupation.正确答案：
1)现在我已回顾了富兰克林,达尔文和莫扎特刚开始事业时的情况。因为这些事雄辩地说明了心理方面的一个深刻的真理,其意义再强调也不过分。2)确实,这是一个长期来并没有充分认识的真理,3)直到前不久,其全部意义才被,才可能被理解。4)只是在最近几年里科学研究才作出种种发现,使得完全认识这一真理成为可能,并变得极其重要,以至于它所涉及到的原则运用到实践中去会立即和极大地提高人的效力,给人类带来幸福和康乐。5)简单地说,这个真理就是生活的成功,即实现个人和社会的真正价值的结果主要取决于坚持不懈的努力,这种努力是来源于对自己所选择的事业深深的和炽热的兴趣。解析： 暂无解析 -
