单选题 In recent months, RAND researchers have teamed up with a dozen Los Angeles lunch trucks to test healthier menu items—chicken breasts and grilled fish alongside the usual tacos and hamburgers. The results have been modest but promising. The healthy meals were never best-sellers, but they did well enough that a majority of the truck owners plan to keep them on the menu.
That"s important, because the trucks tend to serve working-class Latino communities, where obesity rates are high and healthy food can be scarce, leading researcher Deborah Cohen said. "It"s important that the providers are offering these meals," she said. "I think what we showed is that it"s completely feasible."
Cohen has spent years arguing that restaurants, grocery stores and other food outlets should take more responsibility for the nation"s obesity epidemic, and more action to stop it. More than one-third of U. S. adults are obese, according to federal statistics, adding billions of dollars to the nation"s health care costs each year.
A lunch truck may seem like an unlikely testing ground for healthy menu items, the four-wheel equivalent of a fast-food joint. But most are morn-and-pop operations where cooks make food by hand, using fresh ingredients and often for underserved communities. Cohen called them a "good lab."
These aren"t the trendy food trucks that have started to sell fusion tacos and reimagined grilled cheese to hip, young urbanites. These have been part of blue-collar Los Angeles for generations, where they"re known as loncheras, after the Spanglish word lonche, for lunch.
Working with a $ 275,000 grant from the National Institutes of Health, RAND researchers enlisted nearly 20 loncheras for a six-month trial they named "La Comida Perfecta," or "The Perfect Meal" About a third of the truck owners later dropped out, leaving 12 who worked with a nutritionist, created their own healthy meals, and then put them on the menu.
The six-month pilot program didn"t yield big sales numbers at most trucks, but it did yield some valuable insight into the challenges, big and small, of changing food habits, the researchers said. Truck operators had trouble swapping out their corn tortillas for whole wheat, for example, and their Latino customers especially didn"t care for the brown rice that replaced their traditional Mexican rice. Nearly half of the truck customers were regulars, surveys found, and most knew what they wanted without even looking at the menu. In poorer neighborhoods and blue-collar work sites, that was usually a couple of $1 tacos, not a $7 plate with fruit and salad.
单选题 Cohen may agree that ______.
【正确答案】 A
【答案解析】[解析] 推理判断题。原文并未明示或暗示大多数的卡车所有者是肥胖人士,因此B选项错误。文章第一段指出,该实验虽然收效甚微,但是充满希望。因此C选项错误。文章第四段指出,一个午餐车看上去不像是健康菜单的试验场,但是绝大部分午餐车是夫妻合营的,手工做菜,用新鲜的原料,且通常是提供给服务设施不齐全的社区的。Cohen称之为“好的实验室”。据此可知D选项错误。文章第二段指出,那里的肥胖率非常高,健康的食物可以说很稀缺。据此可知缺乏健康饮食最终导致肥胖。因此正确答案为A选项。
单选题 A lunch truck acts as ______.
【正确答案】 D
【答案解析】[解析] 事实细节题。文章第四段指出,Cohen称之为“好的实验室”。这里“实验室”加了引号,它并非真正意义上的实验室,因此A选项错误。文章第三段指出,Cohen花费多年的时间去论证,饭店、杂货店和其他经销店应该更多地承担起国家的肥胖流行病的责任。因此午餐车也不是食品经销店或杂货店。故排除B、C选项。文章第四段指出,一个午矮车看上去不像是健康菜单的试验场,因为四个轮子的卡车就相当于一个快餐店。据此可知,午餐车是移动食品摊位。因此正确答案为D选项。
单选题 According to the text, which of the following is true?
【正确答案】 C
【答案解析】[解析] 事实细节题。原文指出,绝大部分午餐车是夫妻合营的,据此可知A选项错误。文章指出,这些餐车不是卖墨西哥煎玉米融合卷并且把新烤奶酪卖给时髦城市年轻人的新潮餐车。这些车是洛杉矶几代蓝领工人的一部分,据此可知B选项也是错误的。原文第六段“RAND researchers enlisted nearly 20 loncheras for a six-month trial”中“trial”与C选项中的“pilot”是同义替换,该句意为,“RAND研究院赞助了将近20辆午餐车进行为时6个月的试运行”。据此可知C选项为正确答案。D选项文中并未提及,故排除。
单选题 The last paragraph indicates that ______.
【正确答案】 A
【答案解析】[解析] 事实细节题。文章指出,尽管6个月的试点方案并没有突出的销售业绩,但是带来了关于改变饮食习惯大大小小困难的珍贵的理解。因此B选项错误。文章指出,他们的拉美顾客并不介意吃的是糙米还是传统的墨西哥米。据此可知D选项错误。文章指出,将近一半的客人是常客,几乎不用看菜单就知道自己想要什么。据此可知他们并不想改变饮食习惯,因此C选项错误。文章还指出,在更加穷困的社区和蓝领的工作地点,人们通常是想要两个一美元的墨西哥玉米卷饼而不是7美元一盘的有水果和沙拉的健康食物。据此可知A选项正确。
单选题 What"s the best title of this text?
【正确答案】 B
【答案解析】[解析] 主旨大意题。文章并未逐条地介绍健康的饮食习惯,故首先排除A选项。文章并未侧重描写这个好消息是什么以及这个好消息会给蓝领工人带来什么。因此排除C选项。文章的重点也不是介绍完美的饮食是什么,因此D选项错误。文章第一段指出,兰德研究员联手洛杉矶的午餐车提供更加健康的食物菜单,虽然收效甚微,但是充满希望。后面几段也是围绕这个实验展开的,因此本文的最佳题目是“饮食健康试验”。
