Travelite currently offer walking holidays
A. only in Western Europe.
B. all over Europe.
C. outside Europe.
读题：名词关键词是旅行社的名字Travelite, 副词关键词是时间状语currently, 强调的是目前的，不是将来的，也不是过去的(将来和过去的内容在录音中都很有可能出现，进行干扰)。
录音：Thank you for calling our Travelite Walking Holiday Line…We offer guided walking tours to suit the discerning traveler in twelve different centres throughout the whole of Western Europe. We are planning to open our first centre outside this area in the coming year.
解析：旅行社的名字使得听力中很容易定位到题目。答案在the whole of Western Europe, 干扰内容在first centre outside this area, 通过planning与coming year来排除;正确选项为A, 干扰项为C.
因此，问题中关键词划取的快速原则是：名词-动词-形容词/副词。
