Laura Davis grew up in London, far removed from the small country village she later moved to. Although not from an agricultural background, she wasn’t impressed by what she had seen of conventional methods. Joining Laurence on the 32 acre smallholding of Bindon Farm provided a perfect opportunity to develop an organic system of farming.
"It was perfect really," she says. "We never considered using chemicals, so we were organic from the start. The land here had never been intensively farmed, it was all permanent pasture, and in the early days it was more an exercise in self-sufficiency than a working farm. Later, when we decided to operate commercially, we both did part-time courses at the local agricultural college. It was a general course, not particularly geared to an organic system. There is tremendous confusion about what ’organic’ means. We describe organic produce as ’the products of a sustainable system of farming that is environmentally harmless.’ In other words, ’organic’ describes the system of farming rather than the produce itself. All land has a certain amount of naturally occurring chemicals in it. It’s also possible that your produce can be marginally contaminated by, for instance, the farmer next door. So it is wrong to suggest that the product is completely free of chemical residue(残余物,残渣)."
The Soil Association is the body which approves land suitable for organic growing. Their inspectors issue a Soil Association symbol which can be used in the marketing of organic produce. To gain the symbol, land has to be free of chemical use for at least two years— sometimes longer, depending on how it has been used previously. The organic farmer also has to demonstrate competence in organic farming. The Soil Association was in its infancy when Laura and Laurence began and they were among the first to be awarded the symbol.
What does the word "contaminated" (Sentence 9, Para.2) mean?
选项
A、Cleaned.
B、Polluted.
C、Widened.
D、Expanded.
答案
B
解析
依据文章第二段第八句“All land has a certain amount of naturally occurring chemicals in it. It’s also possible that your produce can be marginally contaminated by,for instance,the farmer next door.So it is wrong to suggest that the product is completely free of chemical residue”,尤其是最后一句“因此,认为这些产品完全没有化学残余物是错误的”更能说明contaminated为“弄脏,污染”之意。
