Empathy

Last year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years. __小题1:__ Today, people spend more time alone and are less likely to join groups and clubs.

Good social skills—including empathy—are a kind of “emotional intelligence” that will help you succeed in many areas of life.
