Question

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers(消费者) have been willing to pay up to twice as much for organic goods. However, a study led by researchers at Stanford University says that organic products aren't necessarily more nutritious(有营养的), and they're no less likely to suffer from disease-causing bacteria, either.

The latest results suggest that buyers may be wasting their money, "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford.

For their new study, Smith-Spangler and her colleagues did a review of two kinds of research, including 17 studies that compared health results between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were very small.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn't always translate into a more nutritious or healthier product. Experts state that whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.

【解析】本文从人们花很多钱去购买有机食品出发，质疑了有机食品真的比传统食品更好？接着引用专家的调查结果证实了有机食品并非比传统食品有更多的营养成分。

1.C

细节理解题。根据第二段“The latest results…We did not find strong evidence that organic food is more nutritious or healthier,”(我们没有找到更有利的证据来说明有机食品更有营养更健康。)The latest results与题干中的new research是对应的，本题干问的是“新的调查质疑有机食品…”，因此可得出C是正确的。

2.D

推理判断题。根据第四段中的. “found little difference in nutritional content,…Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards” （发现在营养含量差别不大…无论是有机食品还是传统食品，都没有超出食品安全标准的足够高的化学物质含量。）可知，在第四段中进行了详细的对比，得出两者只有细微的差别，但两者都没有超标的化学物质含量，由此可推断出两者检测是安全的。故选D。

3.A

细节理解题。根据第四段中的“The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease”可知，研究人员发现有机牛奶和有机鸡肉含有一类较高的脂肪酸，这种脂肪酸可以降低患心脏病的风险。故A是正确的。

4.B

观点态度题。作者在第一段提出人们不值得花过多的钱去买有机食品，最后一段最后一句引用美国农业部的观点“whether you buy organic or not,finding the freshest foods available may have the biggest effect on taste.”（无论是否购买有机食品，找到最新鲜的食物才是对口感有最大的影响）可推知，作者对有机食品持怀疑的态度。故B是正确的。
