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.

选项
答案
F
解析
本题可以组合使用代词指代关系定位法和上下文逻辑关系定位法。首先可定位出第4题之前的本段原文信息主要是谈论污染的传播途径,所以原文信息中出现了spreading,而且第4题之前的句子提到了the drugs污染谷物,而谷物被人食用,因而断定第4题中的信息应该继续沿着此主题谈下去,即the drugs如何传播,那么,正确选项中应该出现the drugs的复现结构或者使用代词指代;同时,既然是继续沿着此主题谈下去,上下文的结构应该是并列或者递进的关系。根据上述分析,可以定位到选项F)。它的主语代词they指代the drugs,更为关键的是出现了also这个信息点,说明它与上句之间是并列结构,而且选项F)说“它们也可以通过tap water传播”,就是延续了the drugs如何传播的主题,由此可见选项F)与第4题之前的本段原文信息具有相近性和衔接性,为正确答案。
