　　[解题思路]

　　本题对应于文章第一段的第二句话，即“They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well”( 信用卡持有者可在商店、饭店、宾馆，以及在当地、外地甚至国外赊购货物，同时信用卡还可以使他们得到银行提供的许多服务)。B选项符合该句的内容，是正确选项。A选项很明显是错误的，C选项则在原文中没有提及。D选项的表述过于绝对，该段第三句话中的“scattered locations”(分散的地点)决不意味着“wherever he wishes to”，从常理判断这也是不可能的，因此该选项也是错误答案。
