阅读下列文，从每题所给的 A 、 B 、 C 、 D 四个选项中，选出最佳答案。

To tell you the truth I'm not interested in owing a cellular( 网络 ) phone—except for use in an emergency ( 紧急情况 ) for ordinary cellular phone service is very expensive. How would I get help if I were in trouble or in danger? A good friend told about a product she thought would settle my problem. It's the SOS phone—-a cellular phone service designed for emergency use.

    With the touch of a button the SOS phone will connect me to a roadside emergency service a 911 service or a trained service SOS operator 24 hours a day. If I ever need help I know it's just a phone call away. By pressing the “Tow” button I'll be connected with my emergency roadside service provider( 提供者 ) or if I don't have one ， the SOS operator can suggest one to me and get in touch with them immediately.

    The “ 911” button will connect me to 911 emergency service in my area—best of all the call is completely free!

    If I just want to call home to tell my husband and children something necessary I can by pressing the “Call” button I'll reach an operator when I asked the operator to call home. I'll be connected automatically ( 自动的 ). And because the Call Center has my 10 most-used phone numbers I don't even have to recite the number.

    Unlike ordinary cellular phone plans the SOS phone doesn't have any minimum usage requirements ( 最低底价 ) or other promises that could change the price I expect to pay each month. Why not try it yourself?
