[答案] B

　　[解题思路]

　　本题的对应信息在文章第四段，该段第二句话说“Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist trails”(不过，热情接待陌生人的传统在美国仍然非常流行，尤其是在远离旅游热线的小城镇)，选项符合题意，而D选项与该句的意思相左。A选型与该段最后一句话“The casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition”(很多美国人在不经意间表现出的友好不应被看做是表面应酬或故作姿态，而应该视为是在历史发展中形成的一种文化传统)意思相反，是错误选项。C选项与该段倒数第二句话“Such observations reported by visitors to the US are not uncommon, but are not always understood properly”(来美国的旅客中碰到这种事件的还不少，但他们并非对这个现象都能正确理解)的意思也是相反的，因而也是错误的。
