题目内容

9.Organic(有机的)foods are foods produced according to strict guidelines set forth by the government.These guidelines state that organic foods must be produced without modern man-made processes and materials,such as man-made pesticides (杀虫剂) and chemical fertilizers.
For most history,almost all food was organic.However,during the 20th century,the principles of the Industrial Revolution were applied to agriculture.This led to the development of many man-made processes and products that were believed to improve farming techniques.In other words,sm all farms grew larger as the ideas that were used by factories and big businesses were put into action to grow more food faster.
Over time,the organic movement started to get back to the old,traditional methods of farming.Those in favor of organic food believe that the man-made chemicals and pesticides used in modern farming can be harmful to your health.They also believe that organic foods are naturally more nutritious.
If you go to the grocery store,you will notice that organic foods may be more expensive than non-organic foods.This is partly because of that fact that the government requires organic food producers to obtain special certification(鉴定) for their products.
Is organic food worth the extra co st?Some people believe it is.Despite the lack of scientific findi ngs to support their claims(说法),many people still prefer organic foods.Some people believe they taste better,while others prefer to eat food that has not been grown,made or processed using man-made chemicals.
If you wonder whether you should choose an organic food instead of a non-organic one,the best thing you can do is try for yourself and see which you prefer.Although organic foods were once only available in health food stores,you can find them t oday at most grocery stores.
