Organic Food:Why?

1 Europe is now the biggest market for organic food in the world,expanding by 25 percent a year over
the past 10 years.So what is the attraction of organic food for some people?The really important thing is
that organic sounds more"natural".Eating organic is a way of defining oneself as natural,good,caring,
different from the junk-food-eating masses.
2 Unlike conventional farming,the organic approach means farming with natural,rather than man-
made , fertilisers and pesticides. Techniques such as crop rotation(轮种)improve soil quality and help
organic farmers compensate for the absence of man-made chemicals.As a method of food production,organic
is,however,inefficient in its use of labour and land;there are severe limits to how much food can be pro-
duced.Also,the environmental benefits of not using artificial fertilisers are tiny compared with the amount of
carbon dioxide emitted(排放)by transporting food.
3 Organic farming is often claimed to be safer than conventional farming. Yet studies into organic
farming worldwide continue to reject this claim.An extensive review by the UK Food Standards Agency found
that there was no statistically significant difference between organic and conventional crops.Even where re-
sults indicated there was evidence of a difference,the reviewers found no sign that these differences would
have any noticeable effect on health.
4 The simplistic claim that organic food is more nutritious than conventional food was always likely to
be misleading. Food is a natural product,and the health value of different foods will vary for a number of rea-
sons,including freshness,the way the food is cooked,the type of soil it is grown in,the amount of sunlight
and rain crops have received,and so on.Likewise,the flavour of a carrot has less to do with whether it was
fertilised with manure(粪便)or something out of a plastic sack than with the variety of carrot and how long
ago it was dug up.
5 The notion that organic food is safer than"normal"food is also contradicted by the fact that many of
our most common foods are full of natural toxins(毒素).As one research expert says : " People think that the
more natural something is,the better it is for them.That is simply not the case.In fact,it is the opposite
that is true:the closer a plant is to its natural state,the more likely it is that it will poison you.Naturally,
many plants do not want to be eaten,so we have spent 10,000 years developing agriculture and breeding out
harmful traits from crops."

选项 The weather conditions during the growth of crops________.
A:affect their nutritional content
B:poison you
C:improve soil quality
D:be eaten
E:show that organic crops are safer than conventional ones
F: be specially trained

答案A

解析文章第一段第一句话指出欧洲是现今世界上最大的有机作物生产市场,并且在过去10 年里,每年生产面积扩展达25%。最后三句话讲有机作物受欢迎的原因是因为人们认为有机 作物听起来更天然。故选B。
文章第二段第一句话是主旨句,意思是“和传统种植方法不同,有机作物种植方法意味 着用天然的方法耕种,而不是用人工的、施化肥或使用杀虫剂的方法来耕种。”故选F。
文章第三段讲述了尽管有机作物种植方法一直被宣称是比传统种植方法更安全,但世 界范围里关于有机作物种植方法的研究却一直不认同这一说法。
文章第四段讲认为有机作物比传统种植的作物更营养的说法可能是一种误导。食物 是自然的产物,不同食物的健康价值也因许多原因各不相同。影响食物健康价值的原因包括: 烹饪方法,生长地的土壤,阳光,雨水等等。故选A。
文章第二段描述了有机作物的种植方法。其中第二句话提到:" Techniques such as crop rotation improve soil quality...",故选C。
参考第25题解析。
参考第26题解析,文章第四段提到的天气因素会给食物的健康价值即营养成分造成 影响。
由文章第五段倒数第二句话:" the closer a plant is to its natural state , the more likely it is that it will poison you.”可知作物越接近它的自然状态越有可能对人有害。因此越接近自然状 态的作物,越不适合食用。故选D。
