单选题 Paragraph 1 Junk food is everywhere. We"re eating way too much of it. Most of us know what we"re doing and yet we do it anyway.
Paragraph 2 So here"s a suggestion offered by two researchers at the Rand Corporation: Why not take a lesson from alcohol control policies and apply them to where food is sold and how it"s displayed?
Paragraph 3 "Many policy measures to control obesity (肥胖症) assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods," note the two researchers.
Paragraph 4 "In contrast," the researchers continue, "many regulations that don"t assume people make rational choices have been successfully applied to control alcohol, a substance—like food—of which immoderate consumption leads to serious health problems."
Paragraph 5 The research references studies of people"s behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:
Paragraph 6 Density restrictions: licenses to sell alcohol aren"t handed out unplanned to all comers but are allotted (分配) based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.
Paragraph 7 Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren"t primarily food stores?
Paragraph 8 Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can"t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they"re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.

单选题 What does the author say about junk food?

【正确答案】 B

【答案解析】[解析] author。该题干太抽象，可同时浏览下一题定位词：Rand
回原文阅读，发现第二段首句出现Rand，明白本题出自第一段，虽然第一段没有author一词，但内容就是作者的观点态度。
仔细阅读第一段。看选项，理解选项B与原文的同义替换：widely consumed=eating too much；despite=yet；reputation=know；注意ill一词其实对应原文中junk(垃圾)一词，都是负面含义。其他三个选项中educated，temptation，harm原文首段没有提及。

单选题 What do the Rand researchers think of many of the policy measures to control obesity?

【正确答案】 C

【答案解析】[解析] Rand，policy measures，obesity
回原文继续阅读，发现第三段首句出现policy measures，obesity。
该段说“许多控制肥胖症的政策措施是假定人们是有意识的和理性的”，但researchers并没有评价这些政策措施。但在第四段出现的In contrast后说“那些假定人们不理性的控酒管理规定是成功的”。第三段和第四段联合阅读，归纳出：人们做选择是not rational(不理性的)，控制肥胖症的政策措施不成功，是因为基础假设错了。
本题属于难题，对应原文第二、三、四段，尤其需要对第三、四段意思进行深入理解归纳。注意C选项中：assumption=assume；based on=therefore；wrong=In contrast，not，successfully。
