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.
【C10】

选项 A、although
B、before
C、if
D、as

答案D

解析 本题需填入一个连词,满足句意“对受试者的大脑扫描________他们看各种各样的图片”,空格所在的句子是一个复合句,空格处的连词需引导从句。由句意可知,subjects(受试者)被要求扫描大脑,后面they looked at a variety of images(看各种图片)中的they指的是subjects,扫描的目的是观察受试者看到图片的反应,所以这两个动作应该是同时发生的,空格处所填连词须引导时间状语。四个选项中只有选项[D]as“当……时”符合句意,故为正确答案。
