问题     That health and beauty are linked is not in doubt. But it comes as something of a surprise that who is【C1】______as beautiful depends not only on the heaith of the person in question but also on the【C2】______level of health in the place where she lives. This, though, is the conclusion of a study just published in Biology Letters by Urszula Marcinkowska of the University of Turku, in Finland, and her【C3】______—for Ms. Marcinkowska has found that men in healthy countries think women with the most feminine faces are the prettiest while those in unhealthy places prefer more masculine-looking ones.
    Ms. Marcinkowska came to this conclusion by showing nearly 2,000 men from 28 countries various versions of the same female faces,【C4】______to look less or more feminine, and thus【C5】______the effects of different levels of oestrogen(雌激素)and testosterone(睾丸素). Oestrogen promotes features, such as large eyes and full lips, that are characteristically feminine. Testosterone【C6】______masculine features, such as wide faces and strong chins.
    Statistical analysis shows it is unconnected with a country’s wealth or its【C7】______of men to women and thus the amount of choice available to men. The cause, though, is unclear.
    Previous studies have shown that women with feminine features are more fertile. A man’s【C8】______for them is thus likely to enhance his reproductive success. Ms. Marcinkowska speculates that testosterone-induced behavioural characteristics like【C9】______, which might be expected to correlate with masculine-looking faces even in women(they certainly do in men), help in the competition for resources needed to sustain children once they are born. But why that should be【C10】______important in an unhealthy country is unclear.
A)average B)colleagues C)dominance D)favorable
E)genetically F)majority G)modified H)particularly
I)perceived J)personality K)preference L)promotes
M)ratio N)reflect O)relation
【C7】

选项

答案M

解析 空格位于its后,故应填入一个名词。结合文意,这里指男女比例,故选择ra-tio,意为“比例”,所以此空应选择M)ratio。
