分析 受到强地震的袭击，游客被与外界切断联系，面临着缺水和食物．
解答 答案是A．本题考查分词做状语．分词做状语时分词的选择是看分词和句子主语之间的关系：分词和句子主语之间是主谓关系（主动关系），用现在分词；分词和句子主语之间是动宾关系（被动关系），用过去分词；题干中第一空的hit和主语the visitors之间是被动关系，所以第一空用过去分词，排除C；B项的第一空是现在分词完成式的被动语态，也表示"被动和完成"，同时还强调先后关系；第二空的face和the visitors之间是主动关系，所以选用现在分词，答案选择A．
点评 在非谓语动词的解题中要在掌握其基本用法的基础上关注并积累一些固定用法，结合具体语境做出合理的判断．
