What Does GMO Free Mean?

Genetically modified organisms(GMOs)in food are concern for a number of consumers who are worried about the impact that GMOs may have on their health.As a result,many companies in the late 1990s began to apply the GMO free label,indicating that their food does not contain genetically modified organisms.A number of nations legislate labeling,and in Europe,food must be labeled to indicate whether or not it contains GMOs.In the United States,however,GMO free labeling is purely voluntary and not regulated by any governmental body or organization.
Since it is not regulated,there has been some question about the validity of the GMO free label in the US.A number of organizations have pressured the Food and Drug Administration(FDA),as well as the United States Department of Agriculture(USDA),to enact legislation governing food labeling in regards to GMOs.Many food activists want a label that is standardized,so that consumers who are concerned about this issue can be assured about the GMO content of products they purchase.
Most US consumers have foods containing GMOs in their home.The majority of corn and soybeans grown in the US have been modified,as have several other crops.Some research indicates that many processed foods contain GMO ingredients,so for consumers who are concerned about this issue,GMO free labeling would be helpful.
For consumers who want to eat natural,organic foods,knowing that the products they buy are GMO free is often very important. Although there is no federal labeling program in the US,some organic farmers and natural food producers have chosen to start their own certification programs.Getting certified through such programs can be very difficult,but many producers believe consumers will be willing to pay extra for the verification.
The harmful nature of GMOs has been questioned,especially by commercial agriculture producers and seed providers.No scientific evidence has been found to suggest that genetic modification of crops is harmful to humans. Some consumers feel that it is important to be able to make conscious choices about what they eat,however,and want the ability to choose GMO free foods if they so desire.
Some studies suggest that GMOs may be harmful to agriculture,with cloned genetically modified species harming overall biological diversity and modified genes finding their way into wild plants and non-modified crops.This is especially true in the case of corn,where GMO contamination became a major issue in the 1990s.Other research,however,indicates that genetically modified crops can be of benefit to the environment. Plants designed to be resistant to herbicides（除草剂）and pesticides （杀虫剂）,for example,have been seen to reduce the amount of these chemicals used by farmers on both GM and non-modified crops.
选项 In the last paragraph,"these chemicals"means______.
A:genetically modified crops       
B:herbicides and pesticides
C:genetically modified species       
D:genetically modified genes
答案B
解析题干意思：为什么在20世纪90年代末，很多公司使用不含转基因有机体的食品标签？文中第一段第一句：Genetically modified organisms ( GMOs ) in food are concern for a number of consumers who are worried about the impact that GMOs may have on their health．食物中的转基因有机体引起很多消费者的忧虑，他们担心转基因有机体会对他们的健康有害。显而易见，B选项正确。
题干意思：美国很多组织要求食品和药品委员会______。文中第二段第二句：A number of organizations have pressured the Food and Drug Administration ( FDA ) , as well as the United States Department of Agriculture(USDA),to enact legislation governing food labeling in regards to GMOs．有一些组织向政府食品和药品委员会和美国农业部施压，要求政府通过法律管理食品上的不含转基因有机体标签。经过分析，发现选项C符合文中意思。
题干意思：消费者愿意为……额外付款。通过文中第四段最后一句Getting certified through such programs can be very difficult,but many producers believe consumers will be willing to pay extra for the verification．这一认证项目的难度很大，但是很多生产商相信消费者愿意为这一纸证明额外付费。经过比较只有A选项符合题意。
题干意思：商业农作物生产者和种子供应商质疑______。根据文中第五段第一句The harmful nature of GMOs has been questioned , especially by commercial agriculture producers and seed providers．对转基因有机体的有害性，目前还有疑问，尤其是农产品生产商和种子供应商。通过分析，选项D是正确答案。
题干意思：最后一段“这些化学物品”指的是______。文中最后一段最后一句：Plants designed to be resistant to herbicides and pesticides , for example , have been seen to reduce the amount of these chemicals used by farmers on both GM and non-modified crops．比如一些杭除草剂和杀虫剂的转基因作物就能够减少农民在转基因及非转基因作物上化学药品的用量。回答此类题目一定要在单词的前一句寻找代词指代的对象，该句中能够与these chemicals 对应的只有herbicides and pesticides。所以选择B。
