Students who date (约会）in middle school have significantly worse study skills, are four times more likely to drop out of school and report twice as much alcohol and tobacco use than 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 (调查表）about the students* academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.

　　"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,'1 according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
