根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people.   小题1: The study shows that girls become more depressed than boys, and younger girls are the worst of all.

The possible reason for the connection between love and higher risk of depression for girls is "loss of self". According to the study, even though boys would say "lose themselves in a romantic relationship", this "loss of self" is much more likely to lead to depression when it happens to girls.   小题2:  They won't tell that to their parents. 

Dr. Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression.

She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self.   小题3: 

Parents should watch for signs of depression—eating or mood changes.   小题4:  . The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young.   小题5: .
