Abstract: After analyzing the personal advertisements of 404 Tianjin’s advertisers and 432 Boston’s ones, the findings show：（1）Male advertisers always paid more attention to female appearance and body-figure, and female advertisers think more of male own resources and commitments to the marriages, but Tianjin’s advertisers showed the traits of mate selection above more strongly;（2）As they got older, male advertisers preferred progressively younger partner than themselves, whereas female advertisers exhibited a more stable pattern of preference;（3）Boston advertisers’ choice range for potential partners’ age was larger than Tianjin’s;（4）Tianjin’s advertisers emphasized committed individual characteristic, whereas Boston’s advertisers regarded the ones concerning spiritual communication and life-enjoyment. It was proposed that evolutionary psychological hypothesis was verified concerning the differences between male and female relatively successfully, but explained cultural difference between Sino-America poorly.

Key words: personal advertisements, mate selection criteria, evolutionary psychology, social learning theory
