Fields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs".
The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry.【B1】_______________
Some 20,000 tons antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth.【B2】_______________
Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf.【B3】______________
With millions of tons animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance, he said. The drugs contaminate the crops, which are then eaten.【B4】_______________
Mueller is particularly concerned about a group of antibiotics called sulphonamides.【B5】_____________This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously.
There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and broken down by conventional sewage treatment.
A ) They do not easily degrade or dissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs.
B ) And manure contains especially high levels of bugs that are resistant to antibiotics, he says.
C ) Animal antibiotics is still an area to which insufficient attention has been paid.
D ) But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
E ) His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal feed.
F ) They could also be leaching into tap water pumped from rocks beneath fertilized fields.
G ) There is no doubt that the food and drink is always important to the health.

答案
E
解析
本题可以组合使用代词指代关系定位法和无关词排除法。第1题出现在第二段段末,之前的本段原文已知信息主要描述了“一个在瑞士的researcher(研究员)提出了警告”,同时,这个researcher做了looked at这个动作,此动作在这里就是“监控土地中药物残留的水平”;这说明在紧接着的第1题的信息中应该绕不开。researcher这个人,通过在7个选项中综合排查分析,可以发现一些选项与第1题无关,比如选项B)中的主题词是manure(牲畜粪便);选项C)中的insufficient attention(没有给予足够的重视)与原文不符合;选项D)中存在连接词but,但第1题前后文中看不出转折关系;选项F)和G)明显与第1题之前的段落原文已知信息无关。在选项A)和E)中可以找到与第1题之前的本段原文已知信息有关的信息,因为这两个选项都含有代词his指代那个researcher;但选项A)中出现了sulphonamides,这个概念在第1题之前的本段原文已知信息中并没有提及,而是在第六段才提出并说明,所以从整个文章的布局角度看,选项A)不可能被放在第1题这么靠前的位置;因此,只有选项E)是合适的,特别是选项E)中的主题信息词his findings(他的发现)正好与前面researcher做的looked at这个动作,即“监控土地中药物残留的水平”相吻合,具有明显的正确指代关系,所以选项E)填入第1题与前文是可以连贯衔接的。
