If you feel sad or upset，remember not to watch a happy movie.A sad movie may be more suitable for you.

Some scientists at Ohio State University，the U.S.，have found that sad movies can make people happier.They published their study in a magazine called Communication Research.

    Scientists asked 361 college students to watch a sad movie called Atonement.The movie tells a story of two lovers who were separated.They died during World War II at the end of the movie.The 361 college students answered questions from the scientists before，after and three times during the movie to find out their different feelings，including sadness.

    According to the result of the survey，scientists found out that people felt better after watching the sad movie.Scientists believed this was because the movie made them think about their own lives and relationships.Compared to those of the unlucky lovers in the movie，their lives were full of hope.

    "I want to live my life to the fullest，and this movie has made me think a lot，" one student wrote.

    Silvia Knobloch﹣Westerwick，the leader of the study，explained that bad moods （情绪） would make people more thoughtful. "Good moods are generally a sign that everything is fine.You don't have to worry，and you don't have to think about problems in your life，" she said. "But bad emotions，like sadness，make you feel terrible about your situation.Therefore，seeing a sad movie may make you feel bad，but that will cause you to think more about your own close relationships and value them more."
