A new American study has found that (1) organic farmi ng is not only good for the environment. The study found that organic farm ing could increase profits for farmers. It also found that trees grown org anically could produce better (2) tasting (3) fruit. Scientists from Washi ngton State University organized the study. Their experiment is believed t o be one of the first to compare the effectiveness of organic farming with  other methods. Organic farmers do not use (4) chemicals to increase their  crops or to control insects, weeds and disease. Many people believe eatin g organic food is more healthful than eating food produced with chemicals.  Americans are willing to pay more for organic food products. Organic food  is one of the fastest growing areas of American agriculture. The number o f organic farmers is growing at a rate of about twelve percent each year.  In the study, the scientists grew Golden Delicious apples on three experim ental farms in Washington State. The scientists used a different method on  each farm. On one farm, they treated the apple trees with fertilizer prod ucts and chemicals to kill (5) insects. The scientists used organic farmin g methods to grow apples on the second farm. They used natural wastes as ( 6) fertilizer and biological methods to control insects. On the third farm , the scientists used both methods. They added chemical treatments, but li mited their use. The Washington State University scientists kept detailed  records of their experiment. They measured the different kinds of fertiliz er and chemicals used. They even measured the amount of fuel used by farm  machinery. The scientists produced an (7) environmental report for each gr owing method. Nature magazine reported their findings. The scientists foun d that the organic system took longer than the other methods to earn a pro fit. However, organic farming was the most energy efficient and did the le ast harm to the environment. It provided more profit by the end of the six -year study. People who tasted all the apples said the organic apples tast ed the sweetest. Several agricultural experts praised the study. But other s questioned the findings. They noted that some organic crops might grow w ell in Washington State, but not in other areas. This VOA Special English  AGRICULTURE REPORT was written by George Grow. 注释: (1) (2) (3) (4) (5) ( 6) (7)     organic[ tasting[ fruit[ chemical[ insect[ fertilizer[ environmental[     ]adj.器官的, 有机的 ]n. 尝味,品尝 ]n.水果 ]adj.化学的n.化学制品, 化学 药品n.化学药品 ]n.昆虫, 卑鄙的人adj..虫的, 虫子一样的 ]n.肥料, [动]受精媒介 物 ]adj.周围的,
