C
While we aim to avoid any appearance of baseless theories, it is noteworthy to observe the longstanding practice of putting magnets(磁铁) in cows, a phenomenon that has been carefully unfolding for years. Why are farmers putting magnets in cows?
Known as cow magnets, the devices are placed inside cattle to deal with “hardware disease”. Hardware Disease occurs after an animal eats a metallic object that then makes a hole in the wall of the reticulum, the second stomach room in ruminant animals(反刍动物). This issue arises from the natural eating behaviors of these ruminants, similar to a person at an unlimited food event—quickly and eagerly large bites without sufficient chewing. This fast - paced feeding approach makes them tend to unintentionally consume metal pieces in their food, including broken farm machinery parts, nails and wires used in fencing, for instance.
Metal objects entering the reticulum may result in infections, increased body temperatures, digestive problems, and unease for the animals. To address hardware disease, the main strategy is to prevent metal from entering the cattle's diet. Farmers have also adopted the method of placing cow magnets into the stomach using either a stomach tube or a balling gun. The cow magnet attracts such objects and prevents them from becoming fixed in the animal's tissue. These magnets, once positioned, remain within the animals throughout their lifespan, only being removed after death when the cows pass away or are processed for meat.
Moseley, a Veterinary Medicine professor, states in a hardware disease resource, “The magnet gathers foreign metallic objects, reducing the risk of making a hole in the reticulum.” Research shows a mild magnetic field affects a cow's small blood pathways, improving circulation and aiding recovery without significant impact on the cow or milk quality.

答案： 28.B　细节理解题
[定位句]Known as cow magnets, the devices are placed inside cattle to deal with “hardware disease”.(第二段第一句)
译文:这些装置被称为牛磁铁，它们被放置在牛体内以应对“铁器病”。
[解析]该题问的是为什么要给牛喂磁铁。通读第二、三段尤其是定位句可知，给牛喂磁铁是为了预防铁器病。故选B。
29.D　细节理解题
[定位句]This issue arises from the natural eating behaviors of these ruminants, similar to a person at an unlimited food event—quickly and eagerly large bites without sufficient chewing. This fast - paced feeding approach makes them tend to unintentionally consume metal pieces in their food, including broken farm machinery parts, nails and wires used in fencing, for instance. (第二段最后两句)
译文:这一问题源于这些反刍动物的自然进食行为，(该行为)类似于一个人处于(被提供)无限量食物的活动中−快速而急切地大口进食，没有进行充分咀嚼。这种快节奏的进食方式使它们往往会无意中吃掉(混杂在)食物中的金属碎片，例如破损的农机配件、钉子和围栏上使用的金属线。
[解析]该题问的是反刍动物得铁器病的主要原因是什么。根据定位句可知，反刍动物在没有充分咀嚼食物的情况下快速而急切地大口进食，这样往往会使它们无意中吞掉混杂在食物中的金属碎片，这正是它们得铁器病的主要原因。故选D。
30.D　写作意图题
[解析]通读全文可知，文章第一至三段介绍了在牛体内放置磁铁的原因;最后一段介绍了在牛体内放置磁铁的益处。由此可知，作者写本篇文章的目的是解释在牛体内放置磁铁来预防铁器病的原因。故选D。
31.A推理判断题
[定位句]Research shows a mild magnetic field affects a cow's small blood pathways, improving circulation and aiding recovery without significant impact on the cow or milk quality.(最后一段最后一句)
译文:研究表明，弱磁场会影响牛的小血管，改善血液循环,帮助恢复，而不会对牛或牛奶质量产生重大影响。
[解析]该题问的是符合逻辑的文章续写部分可能是什么。最后一段主要讲牛磁铁的好处，且定位句进一步介绍了弱磁场的作用，由此可推知，下文可能会探索牛磁铁的更多潜在好处。故选A。
