　　Students who date(约会) in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.

　　“Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships,” said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.

　　Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.

　　Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic(学术的) efforts. He found that some students never or hardly ever reported dating from middle to high school, and these students always had the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
