【題目】

Next time if you're unhappy or complaining about your life, don't turn to a cheerful comedy. You might find a tragedy (悲劇) is just the thing you need to make your day bright.

A team of researchers at Ohio State University, US, has found sad movies can make people happier, Science Daily reported last month.

Many people find tragedies make them realize how good their own lives are, the research showed.

Silvia Knobloch Westerwick, leader of the study, told the reporter that tragic stories often focus on themes of love, and this leads viewers to think about their loved ones and count their good and helpful things.

361 college students took part in the study. They were shown a sad movie. The movie was about two lovers who couldn't be together and finally died during World War II. Before and after the movie, the students were asked questions measuring (衡量) how happy the), were with their lives. Researchers also asked them before, after and three more times during the movie to measure various moods, including sadness.

Researchers found that the sadder students felt while watching the movie, the more likely they were to think about real people they had close relationships with in life. This increased their happiness after watching the movie.

Knobloch Westerwick also explained that sad feelings make people more thoughtful.

"Happy feelings show that everything is fine. You don't have to worry. You don't have to think about problems in your life," she said. "But sadness makes you think more seriously about your situation.So seeing a tragic movie may make you sad, but that will make you think more about your own close relationships and be more grateful."
