AChoose the best answer（根据对话内容，选择最恰当的答案）
The smart phone （智能手机） is amazing．It's not only a phone but also a mini-computer．It helps us communicate with others and enjoy our life．There is no question that the smart phone has been an important thing in the modern age．
However，there will be problems when your kids have Blackberries，Iphones or other smart phones．They can surf the Internet anywhere and at any time．For example，they may surf the Internet in class or at the time they should go to bed．
I'm not alarmist （危言耸听的），and I'm not suggesting that parents stop their kids from using smart phones．I think parents need to give their kids proper supervision （监督） so that they can make better use of smart phones．Here are some tips that are easy to follow and cost nothing．
◆Set a good example  Kids always learn things from their parents in daily life．So show your kids the good habits of using smart phones by your own behaviour．
◆Talk  Parents need to talk with their kids about all the possible situations before they appear．Then set some rules before they begin to use smart phones and keep the doors of communication open when they need help．
◆Pay attention to the night  In order to avoid influencing their rest，parents can take away smart phones from their kids to forbid them to send messages or surf the Internet at night．
◆Protect kids'smart phones with passwords （密码）  The password is easy to be set and costs nothing．But it's a good way to stop others from using kids'smart phones and protect their personal information．
