　　雄性動物養(yǎng)孩子

　　The main exception to primate researchers’ general pattern of ignoring interactions between males and infants has been the study of male care among monogamous primates. It has been known for over 200 years, ever since a zoologist-illustrator named George Edwards decided to watch the behavior of pet marmosets in a London garden, that among certain species of New World monkeys males contributed direct care for infants that equaled or exceeded that given by females. Mothers among marmosets and tamarins typically give birth to twins, as often as twice a year, and to ease the female in her staggering reproductive burden the male carries the infant at all times except when the mother is actually suckling it. It was assumed by Kleiman that monogamy and male confidence of paternity were essential to the evolution of such care, and at the same time, it was assumed by Symons and others that monogamy among primates must be fairly rare.

　　Recent findings, however, make it necessary to reverse this picture. First of all, monogamy among primates turns out to be rather more frequent than previously believed (either obligate or

　　facultive monogamy can be documented for some 17-20 percent of extant primates) and second, male care turns out to be far more extensive than previously thought and not necessarily confined to monogamous species, according to Hrdy. Whereas previously, it was assumed that monogamy and male certainty of paternity facilitated the evolution of male care, it now seems appropriate to consider the alternative possibility, whether the extraordinary capacity of male primates to look out for the fates of infants did not in some way pre-adapt members of this order for the sort of close, long-term relationships between males and females that, under some ecological circumstances, leads to monogamy! Either scenario could be true. The point is that on the basis of present knowledge there is no reason to view male care as a restricted or specialized phenomenon. In sum, though it remains true that mothers among virtually all primates devote more time and/or energy to rearing infants than do males, males nonetheless play a more varied and critical role in infant survival than is generally realized.

　　1. The author of the passage mentions the work of Hrdy primarily to

　　A. present an instance of an untenable assumption

　　B. illustrate a consensus by citing a representative claim

　　C. provide evidence that challenges a belief

　　D. highlight a corollary of a widespread view

　　E. offer data that help resolve a debate

　　2. According to the passage, the evolutionary relationship between male care and monogamy is

　　A. incontestable

　　B. immutable

　　C. uncommon

　　D. immaterial

　　E. uncertain

　　3. The author of the passage suggests that it is “appropriate to consider the alternative possibility” because the previous view

　　A. results in a contradiction

　　B. depends on problematic data

　　C. appears less definite given certain facts

　　D. conflates two distinct phenomena

　　E. overlooks a causal relationship between correlated phenomena

　　4. Which of the following statements, if true, would pose the greatest challenge to “the alternative possibility”?

　　A. The number of primate species in which male care of infants is exhibited is greater than the number of primate species that practice monogamy.

　　B. Male care of infants among primates can be seen earlier in the evolutionary record than can monogamy among primates.

　　C. Monogamous relationships among primates can be found in species living in a variety of physical environments.

　　D. Most primate species that practice monogamy do not show any evidence of male care of infants.

　　E. Male care of infants can be observed in some primate species that lack male confidence of paternity.

　　ETS如何考查GRE閱讀文章內(nèi)部的復(fù)雜邏輯

　　新GRE閱讀文章內(nèi)容復(fù)雜程度降低了，但是新GRE閱讀變化在于邏輯復(fù)雜程度升高。考生們想要獲得新GRE閱讀理解的高分，則更加注重文章的內(nèi)在聯(lián)系。這反映了ETS對于影響研究生階段學(xué)術(shù)成功的基本能力的更為深入的把握。

　　新GRE閱讀的文字內(nèi)容復(fù)雜程度有所降低，邏輯復(fù)雜程度持續(xù)增加。而ETS在多年的跟蹤研究后也意識到，恰當(dāng)準(zhǔn)確把握文章內(nèi)部的復(fù)雜邏輯的能力，同研究生階段的成績關(guān)系更大些。下面，我們以一篇樣題為例看一下ETS是如何考查新GRE閱讀文章內(nèi)部的復(fù)雜邏輯：

　　Policymakers must confront the dilemma that fossil fuels continue to be an indispensable source of energy even though burning them produces atmospheric accumulations of carbon dioxide that increase the likelihood of potentially disastrous global climate change. Currently, technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere might double the cost of generating electricity. But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent. Research into better technologies for capturing carbon dioxide will undoubtedly lead to lowered costs.

　　1. The passage implies which of the following about the current cost of generating electricity?

　　It is higher than it would be if better technologies for capturing carbon dioxide were available.

　　It is somewhat less than the cost of electricity transmission and distribution.

　　It constitutes at most half of the delivered price of electricity.

　　It is dwelt on by policymakers to the exclusion of other costs associated with electricity delivery.

　　It is not fully recovered by the prices charged directly to electricity consumers.

　　對上文的邏輯進(jìn)行提煉我們發(fā)現(xiàn)，得出這樣一個邏輯推理鏈條：

　　環(huán)保技術(shù)(technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere)增加一倍發(fā)電成本(double the cost of generating electricity)。環(huán)保技術(shù)不改變傳輸成本(the cost of electricity transmission and distribution)。最終價格(delivered prices)增加不超過50%。
