问题      A question that health conscious consumers may ask when buying produce is whether they are free of pesticides. But currently, there is no federal standard for pesticide free "organically grown" foods grown without synthetic pesticides or fertilizers. The result, says U.S. Senate Agriculture Committee Chairman Patrick Leahy, is that consumers "too often see confusing and unsubstantiated claims such as ’ organically grown’ and ’ natural’ ".
     Currently, 22 states have some kind of certification program or at least requirements for third party certification. Look for the words "certified organically grown" or similar wording. In most cases, that means that no synthetic pesticides have been used in three years and that no synthetic fertilizers have been used in two or three years. Even if your State does not have its own program, you may have seen organically grown produce in the marketplace. If you want to know exactly what that means, ask the store’ s manager or the produce buyer about how the store’ s "organic" produce was grown.
     Legislation to establish a natural standard for organically grown produce is making its way through Congress. The US. Department of Agriculture would be responsible for the certification program. The legislation also would establish standards for processed foods claiming organic ingredients. But in the meantime, if you want to be certain that the produce you eat is pesticide free, you have two options. You can buy your fruits and vegetables from someone you know or you can grow your own.
The author advises consumers to______.
选项 A、look for foods with such words as "certified organically grown"
B、grow their own food without synthetic chemicals
C、buy foods from a seller they often deal with
D、make sure the foods are pesticide free before buying them
答案C
解析 文章最后一句是作者的两个忠告。后一个忠告(自己种)用破折号与前—个隔开，说明作者在此想取得一种特殊效果。其实，读者也不应把这一条建议当真对待，因为，绝大多数人没有时间、没有地方也不知道怎样种庄稼。相反，第—个建议(买熟人的)却是很实际的。因此，B不正确而C对。A不正确，因为许多标签名不副实。
