阅读理解 B
A few years ago, my sister-in-law started to feel concerned about her teenage daughter. What was she doing after school? Where was she spending her time? My niece was an excellent student，and took part in all kinds of after-class activities. Even so, her mum decided to put a tracking app on the kid's phone.
At first, this made my sister-in-law “feel better”. Then the good situation suddenly ended. She recalled，“I found out that she was in a place where she said she wasn't. I went out in the middle of the night and found her walking without shoes in the middle of the street with some friends.” Things went quickly downhill for the mother and the daughter after that.
With 73% of teens having their own smart phones now，according to a new study，more and more of their parents are facing the question: to spy or not?
Ana Homayoun，founder of Green Ivy Educational Consulting，has advised many parents and their kids about this. “I've found teens are more receptive to tracking apps when they are included as part of a family use agreement to improve safety than when they are placed as a secret tool to watch them,” she said. Mark Bell，a father of a teenage girl，said，“We don't have tracking apps，but we have set some ground rules that my daughter must follow in exchange for us providing a smartphone.” For example，his daughter must “friend” him on social media accounts so that he can review posts，and must share all passwords.
When you're trying to build trust，you need to create an environment that encourages it. So，to win their trust，you need to always be straight with your children. “Parents must let children know how and when they'll be watching them,” said Doctor Paul Weigle. If they're not open about it，he warns，it can “greatly damage the relationship between parents and children”.
