单选题 The selfishness of humans is a central assumption of orthodox (传统的) economics, where it is thought to lead to benefits for the economy as a whole. It is what the 18th-centuiy Scottish economist Adam Smith described as the 'invisible hand'. But evolutionary biologists have come to see cooperation and selflessness as a big part of our     29    as a species. During the course of our evolution, they point out, cooperative groups     30    outcompeted groups of cheats.
    So we are inherently cooperative when operating within our own groups. We have also     31    social mechanisms to reinforce actions that benefit the group. 'You could say teamwork at the scale of small groups is the signature     32    of our species,' says evolutionary biologist David Sloan Wilson from Binghamton University in New York.
    But     33    teamwork can include a competition mechanism to promote actions that benefit the group, particularly in larger groups. It's also important; to remember that in-group cooperation evolved partly in response to competition between groups.
    This evolutionary perspective is radically new to economics, and it could be relevant to grand-scale economic problems that require solutions involving cooperation between nations. Take the challenge of getting nations to work together over economic solutions to climate change—a     34    focus in the run-up to climate negotiations in Paris, France, later this year. This is a gargantuan (巨大的) problem from any perspective, but it is     35    an issue of coordination for the sake of the common good at a massive scale, says Wilson. 'The challenge is therefore to     36    at larger scales the coordination and control that takes place more spontaneously at smaller scales,' he says—from multicellular (多细胞的) organisms to village-sized groups of humans.
    'Morality evolved out of cooperation within and competition between groups, so when acting as a single group to tackle global problems we will have to     37    the role of natural selection ourselves,' Wilson says. This might involve pursuing a wide variety of     38    , identifying those that work best, and then creating incentives to cooperate on implementation. 'In some ways it's the opposite of the invisible hand.'

【正确答案】D
【答案解析】空格所在句主谓宾结构齐全,据此可判断应填入副词,作状语。前一句中提到,进化生物学家们认为合作与无私才能给人们带来成功,此句承接上一句说明,在人类进化过程中,能够相互合作的团队______能够胜过那些相互间欺诈的团队,故答案为D项的consistently“一贯地”。 备选项中,G项的essentially“实质上,本质上”和J项的promptly“立即”两个副词与上下文语义不符,故均排除。

【正确答案】F
【答案解析】空格位于名词teamwork之前,据此推断空格处应填入形容词,修饰名词,并与之一起构成句子的主语。上文中说明人类的进化发展离不开合作,本句中的But之后引出了转折:______团队合作中也包含着竞争,再根据空格后的a competition mechanism to promote actions that benefit the group可知,竞争是一种有益于组内提高行动力的机制,由此可知,这种竞争对团队合作来说是有好处的,故答案为F项的effective“有效的”。 备选项中,I项的particular“特别的,特殊的”和K项的remarkable“惊人的”与上下文语义不符,故均排除。
