It seems as if cell phone could be the protection that parents expecting the kids to have freedom and be safe have been looking for. Let's  41  your 11-year-old son is going on a long bike ride with a friend, so they take along your cell phone   42  they need help. Not only could they call you if necessary, but  43 Global Positioning Systems (GPS) equipped on many mobile phones today, your son and his friend could also be  44 easily. Plus, with an additional service, you could track the boys'  45 location. Or consider this: If your daughter is  46  herself and three friends to a concert, she could  47 out exactly how to locate the concert location and get back home by using her equipped cell phone.And through a(n)  48  software package,you could   49  her whereabouts (行踪).
  50 tracking devices as we all consider useful, however, have  51 .If the boys urgently needed help during the ride,  52 might be too late by the time someone found them. And if they wanted to, the concert-going girls could deviate (偏离) from the  53 route and go to a night club after the  54 -they could turn off the phone or leave it in their own car and drive with someone else.
Cell phones and their accompanying programs are tools for   55 children safely today, but all of them are  56  extremely reliable. Under no circumstances does  57 else replace a well-established parent-child relationship  58  love and trust.
If you do decide to let your kids use these devices, don't rely  59 on them for protection. Your children need you watching them－  60  will never take the place of your time, attention, eyes, and ears when overseeing your child's whereabouts.
