Ancient Greek philosopher Aristotle viewed laughter as "a bodily exercise precious to health." But【B1】______some claims to the contrary, laughing probably has little influence on physical fitness. Laughter does【B2】______short-term changes in the function of the heart and its blood vessels, 【B3】______heart rate and oxygen consumption. But because hard laughter is difficult to【B4】______, a good laugh is unlikely to have【B5】______benefits the way, say, walking or jogging does.
【B6】______, instead of straining muscles to build them, as exercise does, laughter apparently accomplishes the【B7】______. Studies dating back to the 1930’s indicate that laughter【B8】______muscles, decreasing muscle tone for up to 45 minutes after the laugh dies down.
Such bodily reaction might conceivably help【B9】______the effects of psychological stress. Anyway, the act of laughing probably does produce other types of【B10】______feedback that improve an individual’ s emotional state.【B11】______one classical theory of emotion, our feelings are partially rooted【B12】______physical reactions. It was argued at the end of the 19th century that humans do not cry【B13】______they are sad but they become sad when the tears begin to flow.
Although sadness also【B14】______tears, evidence suggests that emotions can flow【B15】______muscular responses. In an experiment published in 1988, social psychologist Fritz Strack of the University of Wu rzburg in Germany asked volunteers to【B16】______a pen either with their teeth—thereby creating an artificial smile—or with their lips, which would produce a (n)【B17】______expression. Those forced to exercise their smiling muscles【B18】______more enthusiastically to funny cartoons than did those whose mouths were contracted in a frown,【B19】______that expressions may influence emotions rather than just the other way around.【B20】______, the physical act of laughter could improve mood.
【B13】
选项
A、unless
B、until
C、if
D、because
答案
D
解析
考查逻辑关系。从语法上来看,it是形式主语,而that之后的从句是真正的主语。在这个主语从句中,but连接了前后两个句子,构成了表示对比关系的并列句。but之后的句子大意为:开始流泪时,人才变得悲伤。既然是对比关系,but之前的句子,应该表达相反的含义:人并不是因为悲伤而流泪。这两个短句之间是因果关系,D.because为正确答案。unless“除非”:until“直到…才”;if“如果”,均不符合题意。
