单选题 What would make a smoker more likely to quit, a big reward for succeeding or a little penalty for failing? That is what researchers wanted to know when they assigned a large group of CVS employees (CVS Caremark is the country"s largest drugstore chain by sales), their relatives and friends to different smoking cessation programs.
"Adding a bit of a stick was much better than a pure carrot. These large employers are spending an average of $800 to $900 per employee per year, but in ways that are often blind to normal human psychology" said Dr. Scott Halpern, who led the study. The trial was intended to change that . Researchers randomly assigned the participants to a number of program options and let them decide whether they wanted to participate. The penalty program required participants to deposit $150; six months later, those who had quit smoking would get the deposit back, along with a $650 reward. In the reward-only program, participants were simply offered an $800 payment if they stayed off cigarettes for six months.
The trial, which was described in The New England Journal of Medicine on Wednesday, was the largest yet to test whether offering people financial incentives could lead to better health. Researchers found that offering incentives was far more effective in getting people to stop smoking than the traditional approach of giving free smoking cessation help, such as counseling or nicotine replacement therapy like gum, medication or patches. But they also found that requiring a $150 deposit that would be lost if the person failed to stay off cigarettes for six months nearly doubled the chances of success.
"This is an original set of findings," said Cass R. Sunstein, a Harvard law professor who helped develop some influential ideas in the field of behavioral economics, notably that if the social environment can be changed—for example, by posting simple warnings—people can be nudged into better behavior. "They could be applied to many health issues, like alcoholism, or whenever people face serious self-control problems."
Over all, success eluded most of the study participants. More than 80 percent of smokers in the most popular pure rewards group were still smoking at the end of the study. Even so, researchers say, their success rate was far greater than for those who got the traditional treatment. Smoking is the largest cause of preventable death in the United States. Diseases linked to it kill more than 480,000 Americans a year. And even a small decline could have a big health effect.
单选题 The underlined word "that" in Paragraph 2 refers to the situation that ______.
【正确答案】 C
【答案解析】[解析] 细节题。根据题干关键词Paragraph 2定位到第二段。The trial was intended to change that. 此处的that指代的是斯科特·哈尔彭博士所说的情况,尤其是最后指出的“但他们花钱时却往往对正常人员心理层面上的因素视而不见”。C项“用人单位忽视了他们员工的正常人员心理层面上的因素”是that指代的内容,故C项为正确答案,并排除D项“大型用人单位在他们的员工身上花费太多”。A项“用萝卜比用大棒更糟糕”是对首句字面意思的误解。B项“在体检上的花销比较少”原文没有提及。
单选题 Researchers found that the most effective smoking cessation approach was to ______.
【正确答案】 B
【答案解析】[解析] 细节题。根据题干关键词effective smoking cessation approach定位到第三段。由该段第二句的offering incentives was far more effective和最后一句可知,“提供奖励的效果要好得多”,但对戒烟失败小施惩戒,“戒烟的成功率几乎可以翻一番”,故B项“对(戒烟)失败给予惩戒”为正确答案。A项“提供奖励”的戒烟效果稍好,但是最后一句句首的But转折了语义,最后一句也说明它不是最好的,故排除。根据第二句可知,C项“提供咨询服务”和D项“提供尼古丁替代疗法”都属于免费帮人戒烟的方式,效果暂且不及A项,故排除。
单选题 According to Cass R. Sunstein, the findings of the study can be used in the following fields EX-CEPT the field of ______.
【正确答案】 A
【答案解析】[解析] 细节题。根据题干关键词Cass R.Sunstein定位到第四段。由该段最后一句“这些发现可以应用到很多健康问题方面,如酗酒,或是人面临严重自我控制问题的时候”可知,B项“酗酒”属于C项“健康问题”,而C项和D项“自我控制问题”都属于这些发现的应用领域。A项“警告”与文章中的应用领域无关,符合题干,故A项为正确答案。
单选题 It is implied from the last paragraph that offering financial incentives in the study ______.
【正确答案】 C
【答案解析】[解析] 细节题。根据题干关键词the last paragraph和financial incentives定位到第五段。由该段第二、三句“在研究结束时,最受欢迎的纯奖励组中有超过80%的吸烟者依旧在吸烟。但研究人员表示,即便如此,他们的成功率仍远远超过了传统疗法”可知,即使纯奖励组的参与者大部分仍没戒烟成功,但成功率还是高于传统疗法,这表明提供经济奖励有可能带来公共卫生效益,故C项为正确答案。A项“可以获得最高的成功率”没有推断依据,且与文章主要内容相悖。B项“改变了20%的吸烟者”中的数字不够精准,不符合文中的More than。D项“让大多数参与者成功戒烟”与该段首句“总体而言,大多数研究参与者都没能成功戒烟”不符,故排除。
单选题 The most appropriate title for this passage would be ______.
【正确答案】 A
【答案解析】[解析] 主旨题。根据题干关键词定位到全文,尤其是第一、二段。第一段首句“想让吸烟者戒烟,是对戒烟成功大加奖励还是对戒烟失败小施惩戒,哪个更加有效?”是全文的主题句,说明了下文进行研究的原因;第二段首句借用斯科特·哈尔彭博士的比喻“胡萝卜加一点大棒的效果比纯用胡萝卜更好”进一步对戒烟话题展开阐述,“胡萝卜”指“奖励”,“大棒”指“惩罚”,故A项“奖励还是惩罚,更有利于戒烟?”为正确答案。B项“CVS药店的戒烟方案有效吗?”、C项“纯奖励组比部分惩罚组更受欢迎”和D项“传统戒烟疗法能改善健康吗?”均偏离主旨,不能做文章题目,故排除。
