※ 引述《lovekyoko (匹兹堡的天空)》之铭言： : Studies in restaurants show that the tips left by customers who pay their : bill in cash tend to be larger when the bill is presented on a tray that : bears a credit-card logo. Consumer psychologists hypothesize that simply : seeing a credit-card logo makes many credit-card holders willing to spend : more because it reminds them that their spending power exceeds the cash they : have immediately available. 支持题，注意结论句在讨论什麽。结论句的因果关系大致是: spending power exceeds the cash---willing to spend more 也就是讨论到底是不是因为信用卡logo会让人觉得有较强的支出能力而愿意付多一点钱，主题 在讨论到底会不会因为信用卡logo而想spend more。 答案B是无因无果类型，去除spending power这个因，就不会导致willing to spend more 这个果。AT无因无果类型题目不少，可以去找SV40那题，也是相同概念。 至於答案E，已经跳脱议题焦点，答案E是在讨论用信用卡logo是否会让"使用信用卡"的 量增加，和是否想spend more无关。 : Which of the following, if true, most strongly supports the psychologists’ : interpretation of the studies? : (A)The effect noted in the studies is not limited to patrons who have credit : cards. : (B)Patrons who are under financial pressure from their credit-card obligations : tend to tip less when presented with a restaurant bill on a tray with : credit-card logo than when the tray has no logo. : (C)In virtually all of the cases in the studies, the patrons who paid bills in : cash did not possess credit cards. : (D)In general, restaurant patrons who pay their bills in cash leave larger tips : than do those who pay by credit card. : (E)The percentage of restaurant bills paid with given brand of credit card : increases when that credit card’s logo is displayed on the tray with which : the bill is prepared : 请问B是哪里有支持哩 感觉不出来 : 我是在b跟e做选择 : 所以我选e : e又错哪里?? 感觉这题很绕 所以我迷路了 冏 --
