　　Salty Rice Plant Boosts Harvests 　　Tim Flowers and Tony Yeo, from Sussex Universitys School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. 　　It is estimated that each year more than 100 hectares of agricultural land are lost because salt gets into the soil and stunts plants. The problem is caused by several factors. In the tropics, mangroves that create swamps and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep in. in Latin America, irrigation often causes problems when water is evaporated by the heat, leaving salt deposits behind. 　　To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. 　　1 Which of the following statements about Flowers and Yeo is true? 　　B They are rice breeders. 　　D They are colleagues at an institution of higher learning. 　　A to find ways to prevent water pollution. 　　C to breed rice plants that taste salty. 　　3 Which of the following is NOT mentioned as a cause of the problem discussed in the passage? 　　B The water table has gone down after droughts. 　　D Evaporation of water leaves salt behind. 　　A influence 　　C stop 　　5 The attitude of the author towards the research project is 　　B negative. 　　D indifferent.　　1． D。 分析: 根据被选项的内容特点判定问题是在问这两个人之间的关系。 该题考察考生根据文章细节进行推断的能力。利用题干中的特征词Flowers and Yeo作为答案线索,这样找到答案相关句： 　　Tim Flowers and Tony Yeo, from Sussex Universitys School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. 划线句内容表明Flowers and Yeo是来自生物科学研究院的研究工作者， 结合上下文结构特点：上一段的内容说英国科学家， 他们的工作..，然后紧接着文章就明确的提到具体的研究者的名字， 从这里我们可以推断出的结论是这相邻两段的逻辑关系是概述和具体举例说明。因此可以推出的结论是：这两个人是科学家， 是从事生物研究的工作者。 　　3． C。 利用被选项中的核心词（A： natural barriers; B: water table, drought; C: sea level; D: evaporation）作为答案线索， 在文章中查找相关信息进行一一确认。 　　4． A。分析affect这个词在句子中的含义是影响，因此和 influence是近义词。
