题目分析：
小题1:B 根据下一句But science may have just proved them right because beautiful women are more likely to have daughters than their plainer counterparts, according to a study.说明科学证明漂亮的女人生出漂亮的女儿较多。那么也就是说漂亮的男性较少了。这正和B项相符。
小题2:F 根据前句As parents tend to pass on genes that determine looks, this could result in handsome men becoming rather thin on the ground说明父母会把决定容貌的基因传给子女，那么F项的说法正确，模特的女儿通常都很漂亮，可能追随父母的脚步，继续做模特。故F项符合上下文。
小题3:D 根据下一句When they reached 45, they were asked about the gender of any children they had.说明本句是在小的时候由老师，故D项符合上下文。
小题4:E 根据前一句the unattractive sorts were more likely to have a son.说明下一句应该是与这句意思相似的，故E项正确。
小题5:C 根据下一句So it pays for attractive women to have daughters说明对女人来说容貌更重要，故C项符合上下文的串联
