Research on animal intelligence always makes me wonder just how smart humans are. 【B1】______the fruit-fly experiments described by Carl Zimmer’ s piece in the Science Times. Fruit flies who were taught to be smarter than the average fruit fly【B2】______to live shorter lives. This suggests that【B3】______bulbs burn longer, that there is an【B4】______in not being too bright.
Intelligence, it【B5】______, is a high-priced option. It takes more upkeep, burns more fuel and is slow【B6】______the starting line because it depends on learning—a(n) 【B7】______process—instead of instinct. Plenty of other species are able to learn, and one of the things they’ve apparently learned is when to【B8】______.
Is there an adaptive value to【B9】______intelligence? That’ s the question behind this new research. Instead of casting a wistful glance【B10】______at all the species we’ve left in the dust I.Q.-wise, it implicitly asks what the real【B11】______of our own intelligence might be. This is【B12】______the mind of every animal we’ ve ever met.
Research on animal intelligence also makes us wonder what experiments animals would【B13】______on humans if they had the chance. Every cat with an owner,【B14】______, is running a small-scale study in operant conditioning. We believe that【B15】______animals ran the labs, they would test us to【B16】______the limits of our patience, our faithfulness, our memory for locations. They would try to decide what intelligence in humans is really【B17】______, not merely how much of it there is. 【B18】______, they would hope to study a(n)【B19】______question: Are humans actually aware of the world they live in?【B20】______the results are inconclusive.
【B5】
选项
A、insists on
B、sums up
C、turns out
D、puts forward
答案
C
解析
考查上下文理解及短语辨析。前文说“聪明的果蝇寿命往往较短”,“不太聪明是有优势的”,由此推断出:聪明是有代价的。后面是对代价的解释,比如将会消耗更多的补给。因此C.turns out符合语境。从语法上看,it turns out…经常用来表示“结果是,原来是,证明是”,故选C。insist on“坚持”,sum up“总计,总结”,put forward“提出”,均不符合题意。
