  一、考试概述:本次考试的文章是三篇旧文章,难度中等。第一篇讲了有调查研究显示,美国市中心出现了食物沙漠的现象“food desert”,住在市中心的市民往往收入较低,无法购买健康食品,同时市中心土地面积少而贵,超市无法自给自足出售蔬菜等,于是面临着健康食物稀缺的问题。第二篇讲了考古学家挖掘出这个古城,讲述了它是怎样发展成一个城市,城市的构造和体系以及为什么能发展成为一个大城市。第三篇讲了一些濒危蜥蜴的现状,如skink,以及介绍了如何拯救这些濒危蜥蜴的方法。
  二、具体题目分析
  Passage 1:
  题目:如何走出食物沙漠
  题型:填空题5 + 判断题7
  题号:旧题
  相似文章:How to find a way out of “food desert”
  A
  Food deserts can be described as geographic areas where residents’ access to affordable, healthy food options (especially fresh fruits and vegetables) is restricted or nonexistent due to the absence of grocery stores within convenient travelling distance. For instance, according to a report prepared for Congress by the Economic Research Service of the US Department of Agriculture, about 2.3 million people (or 2.2 percent of all US households) live more than one mile away from a supermarket and do not own a car. [1] In urban areas, access to public transportation may help residents overcome the difficulties posed by distance, but economic forces have driven grocery stores out of many cities in recent years, making them so few and far between that an individual’s food shopping trip may require taking several buses or trains. In suburban and rural areas, public transportation is either very limited or unavailable, with supermarkets often many miles away from people’s homes.
  B
  The other defining characteristic of food deserts is socio-economic: that is, they are most commonly found in communities of color and low-income areas (where many people don’t have cars). Studies have found that wealthy districts have three times as many supermarkets as poor ones do, [2] that white neighborhoods contain an average of four times as many supermarkets as predominantly black ones do, and that grocery stores in African-American communities are usually smaller with less selection. [3] People’s choices about what to eat are severely limited by the options available to them and what they can afford—and many food deserts contain an overabundance of fast food chains selling cheap “meat” and dairy-based foods that are high in fat, sugar and salt. Processed foods (such as snack cakes, chips and soda) typically sold by corner delis, convenience stores and liquor stores are usually just as unhealthy.
  C
  Food Empowerment Project’s report, “Shining a Light on the Valley of Heart’s Delight (PDF),” shows that it is possible to overlook communities that are located in food deserts when relying on data collected by the US government. We found that, “Part of the problem is how the US government’s North American Industry Classification System (NAICS is the standard used by the federal statistical agencies in classifying business establishments) categorizes retail outlets that sell food. According to the NAICS code, small corner grocery stores are statistically lumped together with supermarkets, such as Safeway, Whole Foods Market, etc. In other words, a community with no supermarket and two corner grocery stores that offer liquor and food would be counted as having two retail food outlets even though the food offered may be extremely limited and consist mainly of junk food.”
  D
  In addition to this, we found that many of the convenience stores that had items such as a bunch of bananas or a few apples would sell the fruits individually. Because these items are not priced, the customers are often at the mercy of the person behind the counter who determines the cost then and there. Customers who don’t have a good understanding of English might never ask the price of the item.
  E
  Those living in food deserts may also find it difficult to locate foods that are culturally appropriate for them, and dietary restrictions, such as lactose intolerance, gluten allergies, etc., also limit the food choices of those who do not have access to larger chain stores that have more selection. Additionally, studies have found that urban residents who purchase groceries at small neighborhood stores pay between 3 and 37 percent more than suburbanites buying the same products at supermarkets.
  F
  Healthier foods are generally more expensive than unhealthful foods, particularly in food deserts. For instance, while the overall price of fruits and vegetables in the US increased by nearly 75 percent between 1989 and 2005, the price of fatty foods dropped by more than 26 percent during the same period. While such inflation has strained the food budgets of many families regardless of their financial status, the higher cost of healthy foods often puts them entirely beyond the monetary means of many lower-income people.
  G
  While unhealthy eating may be economically cheaper in the short-term, the consequences of long-term constrained access to healthy foods is one of the main reasons that ethnic minority and low-income populations suffer from statistically higher rates of obesity, type 2 diabetes, cardiovascular disease, and other diet-related conditions than the general population.
