题目

Organic food has more of the antioxidant (抗氧化剂) compounds linked to better health than regular food, according to the most comprehensive scientific analysis to date. The international team behind the work, led by a professor at Newcastle University, concludes that there are "statistically significant, meaningful" differences, with a range of antioxidants being "actually higher" in organic food.What does the research discussed in this passage conclude?A. Organic food contains higher levels of antioxidants than regular food.B. The amount of protein in organic food is similar to that in regular food.C. Antioxidants bear no direct links to a reduced risk of most cancers.D. Organic food provides twice as much nutrition as in regular food.

题目解答

答案

我们来逐步分析这道题目。

第一步：理解题目要求

题目要求我们根据提供的段落，判断研究的结论是什么，并从四个选项中选择正确的一个。

第二步：阅读并理解段落内容

段落的大意如下：

> 根据迄今为止最全面的科学分析，有机食品比普通食品含有更多的与健康改善相关的抗氧化剂化合物。由纽卡斯尔大学的一位教授领导的国际研究团队得出结论：存在“统计上显著、有意义的”差异，多种抗氧化剂在有机食品中的含量“确实更高”。

关键词：

  • Organic food（有机食品）
  • Antioxidants（抗氧化剂）
  • Higher levels（更高含量）
  • Statistically significant, meaningful differences（统计上显著、有意义的差异）

第三步：分析选项

我们逐个分析选项：

A. Organic food contains higher levels of antioxidants than regular food.

  • 这个选项说：“有机食品中的抗氧化剂含量比普通食品更高。”
  • 这与原文中“a range of antioxidants being 'actually higher' in organic food”完全一致。
  • 这个选项是正确的。

B. The amount of protein in organic food is similar to that in regular food.

  • 这个选项说的是蛋白质含量，但原文没有提到蛋白质。
  • 无关信息，排除。

C. Antioxidants bear no direct links to a reduced risk of most cancers.

  • 这个选项说抗氧化剂与降低癌症风险没有直接联系。
  • 但原文提到抗氧化剂与“better health”有关，暗示有健康益处。
  • 与原文内容矛盾，排除。

D. Organic food provides twice as much nutrition as in regular food.

  • 这个选项说有机食品的营养是普通食品的两倍。
  • 原文并没有提到“两倍”或“所有营养”。
  • 夸大其词，排除。

第四步：得出结论

正确答案是：

$\boxed{A}$

解析

本题考查对文章内容的理解和对研究结论的提取。解题思路是先明确题目要求，即找出文章中研究的结论，然后仔细阅读文章，提取关键信息，最后将各选项与文章关键信息进行逐一比对。

  1. 文章明确指出“Organic food has more of the antioxidant (抗氧化剂) compounds linked to better health than regular food”，意思是有机食品比普通食品含有更多与健康改善相关的抗氧化剂化合物。
  2. 接着又提到“a range of antioxidants being 'actually higher' in organic food”，进一步强调多种抗氧化剂在有机食品中的含量确实更高。
  3. 对各选项进行分析：
    • 选项A：“Organic food food contains higher levels of antioxidants than regular food.”，该选项表明有机食品中的抗氧化剂含量比普通食品更高，与文章中“多种抗氧化剂在有机食品中的含量确实更高”的表述一致，所以该选项正确。
    • 选项B：“The amount of protein in organic food is similar to that in regular food.”，文章中并未提及蛋白质的相关内容，此选项属于无关信息，应排除。
    • 选项C：“Antioxidants bear no direct links to a reduced risk of most cancers.”，文章提到抗氧化剂与“better health”有关，暗示有健康益处，而该选项说抗氧化剂与降低癌症风险没有直接联系，与原文内容矛盾，应排除。
    • 选项D：“Organic food provides twice as much nutrition as in regular food.”，文章没有任何信息表明有机食品的营养是普通食品的两倍，此选项夸大其词，应排除。
