问题     Why do we have the political opinions we have and not another? How and why do our【C1】________change? The answers to these questions are complex. Differences of opinion are shaped by【C2】________life experiences: where you live; how you were【C3】________; whether you’re rich or poor. Emotion comes into the picture, and emotion has a【C4】________basis, at least in part. All of this and more combines into a mixed dish【C5】________a fixed recipe, even if many of the ingredients are known.
    Surprisingly, a recent experimental psychology suggests, our political beliefs may have【C6】________to do with a specific aspect of our biological makeup. In the mid-2000s, a political scientist【C7】________the neuroscientist Read Montague with a radical proposal—political orientation might be partly inherited, and might be【C8】________by our physiological reactivity to threats. To test their theory, they wanted Montague, who【C9】________the Human Neuroimaging Laboratory at Virginia Tech, to scan the brains of subjects【C10】________ they looked at a variety of images—including ones displaying disgusting scenes【C11】________ badly injured animals and dirty toilets—to see whether neural responses showed any【C12】________ with political ideology.
    Montague【C13】________ laughed at the idea, but the team returned with studies to argue their case, and eventually he signed on. 【C14】________ the data began rolling in, any skepticism about the project quickly【C15】________. The subjects, 83 in total, were first shown a random【C16】________ of neutral and emotionally provocative pictures—this second category contained both positive and negative images—while【C17】________ brain scans. Then they filled out a questionnaire seeking their views on hot-button political and social issues, in order to classify their general outlook on a【C18】________ from extremely liberal to extremely conservative. As Montague mapped the neuroimaging data against ideology, he recalls, "my jaw dropped." The brains of liberals and conservatives reacted in wildly different ways to【C19】________ pictures: Both groups reacted but different brain networks were stimulated. Just by looking at the subjects’ neural responses, in fact, Montague could【C20】________ with more than 95 percent accuracy whether they were liberal or conservative.
【C8】

选项 A、concealed
B、acclaimed
C、revealed
D、emphasized

答案C

解析 本题需填入一个动词,满足句意“政治倾向可能部分遗传,并可能通过我们对威胁的生理反应________。”根据句意,政治倾向既然是可以遗传的,那么在我们受到一定的生理刺激后应该会“体现或显露”我们的某种情绪(政治倾向),所以空格处所填动词应表达“激发或释放”这一词义,四个选项中只有选项[C]revealed意为“显示;揭露”符合句意,故为答案。
