问题     Ancient Greek philosopher Aristotle viewed laughter as "a bodily exercise precious to health." But【C1】______some claims to the contrary, laughing probably has little influence on physical fitness. Laughter does【C2】______short-term changes in the function of the heart and its blood vessels, 【C3】______heart rate and oxygen consumption. But because hard laughter is difficult to【C4】______, a good laugh is unlikely to have【C5】______benefits the way, say, walking or jogging does.
    【C6】______, instead of straining muscles to build them, as exercise does, laughter apparently accomplishes the【C7】______, studies dating back to the 616930’s indicate that laughter【C8】______muscles, decreasing muscle tone for up to 45 minutes after the laugh dies down. Such bodily reaction might conceivably help【C9】______the effects of psychological stress. Anyway, the act of laughing probably does produce other types of physical feedback, that improve an individual’s emotional state. 【C10】______one classical theory of emotion, our feelings are partially rooted in physical reactions. It was argued at the end of the 6169th century that humans do not cry because they are sad but they become sad when the tears begin to flow.
    Although sadness also【C11】______tears, evidence suggests that emotions can flow【C12】______muscular responses. In an experiment published in 616988, social psychologist Fritz Strack of the University of Wurzburg in Germany asked volunteers to hold a pen either with their teeth-thereby creating an artificial smile - or with their lips, which would produce a(n) 【C13】______expression. Those forced to exercise their smiling muscles【C14】______more enthusiastically to funny cartoons than did those whose months were contracted in a frown, 【C15】______that expressions may influence emotions rather than just the other way around, similarly, the physical act of laughter could improve mood.
【C7】
选项 A、opposite
B、impossible
C、average
D、expected
答案A
解析 A．opposite“相反的”；B．impossible“不可能的”：C．average“平均的”；D．expected“期待的”。第二段第二句的意思是说“笑可以放松肌肉，在狂笑平息之后45分钟内会降低肌肉张力”，跟上文中的“其他的锻炼可以拉紧增强肌肉”是相反的关系，故答案为A。
