完形填空
Research on animal intelligence always makes me wonder just how smart humans are. 【C1】______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【C2】______to live shorter lives. This suggests that【C3】______bulbs burn longer, that there is an【C4】______in not being too bright. Intelligence, it【C5】______, is a high-priced option. It takes more upkeep, burns more fuel and is slow【C6】______the starting line because it depends on learning—a(n) 【C7】______process—instead of instinct. Plenty of other species are able to learn, and one of the things they've apparently learned is when to【C8】______. Is there an adaptive value to【C9】______intelligence? That' s the question behind this new research. Instead of casting a wistful glance【C10】______at all the species we've left in the dust I.Q.-wise, it implicitly asks what the real【C11】______of our own intelligence might be. This is【C12】______the mind of every animal we' ve ever met. Research on animal intelligence also makes us wonder what experiments animals would【C13】______on humans if they had the chance. Every cat with an owner,【C14】______, is running a small-scale study in operant conditioning. We believe that【C15】______animals ran the labs, they would test us to【C16】______the limits of our patience, our faithfulness, our memory for locations. They would try to decide what intelligence in humans is really【C17】______, not merely how much of it there is. 【C18】______, they would hope to study a(n)【C19】______question: Are humans actually aware of the world they live in?【C20】______the results are inconclusive.
【答案解析】考查上下文理解。“we’ve lett in the dust I.Q.-wise”是定语从句,修饰the species。cast a glance at…意为“对…投以目光”;leave sb.in the dust意为“将某人远远抛在后面”;I.Q.-wise是派生词,意为“在I.Q.方面”,后缀-wise表示方式。这句话是说“该研究的目的不是要我们可怜那些智力不如我们的物种。”人类看这些被抛在后面的物种,自然是往后看了,所以D.backward为正确选项。upward“向上地”,forward“向前地”,afterward“以后,后来”,均不符合题意。
单选题11.【C11】
【正确答案】
D
【答案解析】考查上下文理解与名词辨析。此处意为“这项研究含蓄地提出一个问题:人类拥有智慧的真正——可能是什么”。上文一直都在强调智力带来的代价,“不特别聪明是一种优势”,“智力需要付出高昂的代价”,因此应选D.costs“代价”,与上文Intelligence…is a high-priced option相呼应。feature“特征”;influence“影响”;result“结果”,均不符合题意。
单选题12.【C12】
【正确答案】
B
【答案解析】考查固定搭配。on one’s mind或on the mind of sb.是固定短语,意为“惦念,总是想着”,其他三项均不能与mind构成固定搭配,在语法关系上就可以排除。因此选B.on。
单选题13.【C13】
【正确答案】
C
【答案解析】考查动词辨析。此处正常语序应是animals would——what experiments on humans。perform experiments on humans指“对人类做实验”,符合语境。所以选C.perform“执行”。deliver“递送,交付”,apply“应用”,都无法和experiments搭配。若用carry,固定搭配是carry out experiments,故被排除。
