     Doomed (注定失败的) beauties such as Cleopatra and Marilyn Monroe were far from alone in their

misery(痛苦, 不幸). Very attractive people tend to form partnerships that are less stable and satisfying

than those enjoyed by plain Jane.

     According to the research by Dr John Blaine of the University of Southern California, relationships

between people whose professions largely depend on their appearances, such as, models or actors, tend

to end much faster than those between lawyers, doctors or students.

     Blaine said the beautiful felt different from childhood. They are treated as special, which may create

both arrogance (傲慢) and insecurity. All too often, beauty can be used as an alternative to education.

Often they are pushed out of their class or town, told to go off and make their fortune in Hollywood or

London and, when the majority fail, they have few talents to make a living.

     Blaine added that beautiful people score poorly on the "big five"-the key factors American experts

consider when helping distressed couples. These are neuroticism (神经过敏), including anger and anxiety;

extroversion (性格外向); openness to new experiences; agreeableness; and conscientiousness, or sticking

by agreements they have made. Attractive people often see no reason to try to change until their looks start

to fade.

     Krista Sutherland of the University of California Los Angeles, said partnerships that appeared to be

perfect from the outside, such as the former "dream teams" of Nicole Kidman and Tom Cruise or Hugh

Grant and Elizabeth Hurley, where backgrounds and aspirations (抱负) are often shared, did not necessarily

lead to happiness.
