问题 下面的短文后有2项测试任务：（1)第23~26题要求从所给的6个选项中为第1~4段， 每段选择1个最佳标题；（2)第27~30题要求从所给的6个选项中为每个句子确定1个最佳选项。
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 produced. 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 ciaimed to be safer than conventionalfarming. Yet studies into organic farming worldwide continue to reject this claim. An extensive review by tk ^ Standards Agency found that there was no statistically significant difference between organic and conventional crops. Even where results indicated there was evidence of a difference, the reviewers found no sign that these differences would have any noticeable e行ect on health.
4 The simplistic claim that organic food is more nutritious than conven_ always likely to be misleading. Food is a natural product，and the health value of foods will vaty for a number of reasons，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 (类便）or something out of a plastic sack than with the variety of carrot and how long ago it wasdugup.
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.”
Paragraph 2
选项 A Research into whether organic food is better
Bescription of organic farming
Cactors that affect food health value
D Necessity to remove hidden dangers 什om food
E Main reason for the popularity of organic food
F Testing the taste of organic food
答案B
解析本段第一句讲有机农业不同于传统农业因为它是自然的不是人工的，第二句讲一些 技术比如轮种可以提高土地质量弥补缺乏人工化学药物的缺陷，第三句讲有机农业在人 力、土地的使用效率，粮食产量上存在局限，最后一句讲有机农业中不使用人工化肥所 带来的环境效益很小，所以本段主要是对有机农业的相关描述。答案是B。
