Therefore, through sociolinguistic study, the proverbs about appearance and inwardness of female, as well as the proverbs contrasting male and female in the aspects of social status, age, behavior and marriage are illustrated. The paper will show the linguistic sexism in English proverbs, analyze the reasons and propose its development tendency.
