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 “substantially higher” in organic food. The increased levels of antioxidants are equivalent to “one to two of the five portions of fruits and vegetables recommended to be consumed daily” and would therefore be significant and meaningful in terms of human nutrition. It is the first study to demonstrate clear and wide-ranging differences between organic and conventional fruits, vegetables and cereals.The Newcastle University’s research, published in the British Journal of Nutrition, is based on an analysis of 343 peer-reviewed studies from around the world – more than ever before – which examine differences between organic and conventional fruits, vegetables and cereals. The researchers conclude that many antioxidants have previously been linked to a reduced risk of chronic diseases such as cardiovascular diseases and certain cancers. But they also note that no long-term studies showing health benefits from a broad organic diet have yet been conducted.The findings will bring to the boil a long-simmering (酝酿) debate over whether those differences in antioxidant levels mean organic food is better for people. A professor of nutrition at King’s College London, said, “The question is whether they are within natural variation, or whether they are nutritionally relevant.”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
我们来一步一步地分析这道题:
第一步:理解题干
题目问的是:
> “What does the research discussed in this passage conclude?”
> (文中讨论的研究得出了什么结论?)
也就是说,我们需要从文章中找出研究的主要结论。
第二步:定位关键信息
在文章中,有几个关键句子可以帮助我们找出研究结论:
-
“Organic food has more of the antioxidant compounds linked to better health than regular food, according to the most comprehensive scientific analysis to date.”
——有机食品比普通食品含有更多与健康相关的抗氧化剂化合物。 -
“The international team behind the work, led by a professor at Newcastle University, concludes that there are ‘statistically significant, meaningful’ differences…”
——研究团队得出结论,有机食品和普通食品之间存在“统计上显著、有意义的”差异。 -
“…with a range of antioxidants being ‘substantially higher’ in organic food.”
——有机食品中多种抗氧化剂的含量“显著更高”。 -
“It is the first study to demonstrate clear and wide-ranging differences between organic and conventional fruits, vegetables and cereals.”
——这是首次证明有机食品与普通食品之间存在广泛而明确的差异。
这些句子都明确指出,有机食品的抗氧化剂含量显著高于普通食品。
第三步:分析选项
我们逐个来看选项:
A. Organic food contains higher levels of antioxidants than regular food.
✅ 这与文章中的结论完全一致。研究明确指出有机食品中的抗氧化剂含量显著更高。
B. The amount of protein in organic food is similar to that in regular food.
❌ 文章没有提到蛋白质含量的比较,所以这个选项无关。
C. Antioxidants bear no direct links to a reduced risk of most cancers.
❌ 文章中说的是抗氧化剂曾被证明与降低某些癌症风险有关,而不是说没有关联。
D. Organic food provides twice as much nutrition as in regular food.
❌ 文章中没有提到“营养是普通食品的两倍”,这是夸大其词,不符合原文。
第四步:得出结论
根据文章内容和选项分析,正确答案是:
$\boxed{A}$
解析
本题考查对文章中研究结论的理解和提取能力。解题思路是先明确题干要求,即找出文中研究的结论,然后在文章中定位与研究结论相关的关键信息,最后将各选项与关键信息进行逐一比对分析。
- 定位关键信息:
- 文中提到“Organic food has more of the antioxidant compounds linked to better health than regular food, according to the most comprehensive scientific analysis to date.”,表明有机食品比普通食品含有更多与健康相关的抗氧化剂化合物。
- “The international team behind the work, led by a professor at Newcastle University, concludes that there are ‘statistically significant, meaningful’ differences…”说明研究团队得出有机食品和普通食品存在“统计上显著、有意义的”差异。
- “…with a range of antioxidants being ‘substantially higher’ in organic food.”进一步指出有机食品中多种抗氧化剂的含量“显著更高”。
- “It is the first study to demonstrate clear and wide - ranging differences between organic and conventional fruits, vegetables and cereals.”强调这是首次证明有机食品与普通食品之间存在广泛而明确的差异。
- 分析选项:
- A选项:“Organic food contains higher levels of antioxidants than regular food.”与文章中有机食品抗氧化剂含量显著高于普通食品的结论一致,该选项正确。
- B选项:“The amount of protein in organic food is similar to that in regular food.”文章中并未提及蛋白质含量的比较,此选项与原文无关,错误。
- C选项:“Antioxidants bear no direct links to a reduced risk of most cancers.”文章提到抗氧化剂曾被证明与降低某些癌症风险有关,并非没有关联,该选项错误。
- D选项:“Organic food provides twice as much nutrition as in regular food.”文章没有提到有机食品的营养是普通食品的两倍,这是对原文的夸大,该选项错误。
