四六级大纲在阅读理解部分都指出：测试学生通过阅读获取书面信息的能力
常见表因果的词语：because, why, the reason, for, so, since, as a result等。
同样值得注意的是：当why引导一个问句时，考点出处往往是紧接着回答此问题的句子或相邻的几个罗列点或相连几段话的首句。
例：(因果)American tourists, however, shouldn’t expect any relief soon. The dollar lost strength the way many marriages break up- slowly, and then all at once. And currencies don’t turn on a dime. So if you want to avoid the pain inflicted by the increasingly pathetic dollar, cancel that summer vacation to England and look to New England. There, the dollar is still treated with a little respect.
55. What is the author’s advice to Americans?
A. They treat the dollar with a little respect
B. They try to win in the weak-dollar gamble
C. They vacation at home rather than abroad
D. They treasure their marriages all the more.
【答案】C
【解析】面对美元贬值给美国人带来的民族自尊上的困扰，作者给美国人提出建议：如果想要避免困扰，最好取消去英国的旅行，转而前往新英格兰(美国的一个地区)旅行。换句话说，作者建议取消去国外的旅行，转而在国内旅行。
