（英译汉）A persons physical attractiveness often determines whether we will develop an acquaintance or a friendship with that person. It often influences how we look upon the personality of others. Attractive people are considered more sociable, independent and exciting. Similarly, attractive people are apparently not unaware of the effect of their physical attraction on other people. Being attractive may help determine the way that people actually behave. Attractive men are more confident than less attractive men. They also have less fear of rejection and mix more with women than with men. Curiously, however, attractive women are not always as confident as women who are less attractive, and both groups of women have about the same number of social contacts.
