The phrase bird-brain may be used to describe someone being silly, but this is not the case for ravens. Long 【C1】______for their intelligence, ravens are now known to be able to plan ahead, a skill previously thought to belong only to humans. Researchers learned ravens could remember key information for a future task through tests. Until now, some corvids—the family of birds that 【C2】______ravens—have shown the【C3】______to plan beyond the present, for example by 【C4】______food for later.
But the latest experiments revealed that ravens can 【C5】______forego an immediate reward in order to get a better one in the future. In one of the tests, ravens were trained to use a tool to open a puzzle box in order to 【C6】______a reward. And then, the ravens were presented with a tool to open a box and an immediate reward, but were only 【C7】______to choose one or the other. Ravens remembered that the reward in the box was better than the immediate reward, and almost all of them chose the tool.
Ravens’ 【C8】______for planning is still unknown, but it may be similar to ours. The human brain stores memories of past events to guide decision-making about 【C9】______and future events. Planning tends to come about when the higher 【C10】______of a future reward is palpable, or when one imagines the happiness that will come by retrieving food in the future.
【C4】
选项
答案
H
解析
空格前是介词by,空格后是名词food,因此空格处应填入一个动名词作by的宾语,表示“通过……途径"之意。上文提到,渡鸦能够计划未来,由此可以推测,这里是说它们会事先把食物藏起来,等到以后再吃,故H项hiding为答案。
