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.
【C2】
选项
答案
I
解析
分析空格所在句的句子结构可知,空格所在句包含一个由that引导的定语从句,该从句缺少谓语,因此,空格处应该填入一个动词作从句谓语。空格前面提到了corvids“鸦科鸟类”,空格后提到了ravens“渡鸦”,由此不难推断此处是说包括渡鸦在内的鸦科鸟类,故I项includes为答案。
