D
Cows love having an open area of grassland to graze on. But in some parts of the world, this is only feasible during summer. In winter, it can become too cold for cows to stay outside safely, so they are kept in large farm buildings for warmth. Being stuck inside is not always pleasant for cattle, and their unhappiness is closely connected to reduce milk production.
For this reason, some cattle owners have fitted their cows with VR headsets that run a specific program. The program simulates grasslands in summer and was designed specifically for the way that cows get color and light. According to the National Library of Medicine, cattle see shades of red the easiest but have a hard time distinguishing between blue and green.
Reports from a farm in Moscow, Russia—where the VR headsets were first developed by vets—found in 2019 that the cows that used the VR headsets saw a decrease in anxiety and an improved mood. This led to an increase in milk production, which went from 5.8 gallons to 7 gallons per day.
Cattle owner Izzet Kocak from Aksaray, Turkey, heard about this experiment and tried the VR headsets on his cows in December 2021. When Kocak put the headsets on his cows, he found an improvement in their emotional well-being of his animals. “They are watching an area of grassland, and it gives them an emotional boost. They are less stressed,” he said.
The technology is now spreading around the world. According to the report, the headsets were made specifically for the “structural features of cow heads” by vets, and the animals were shown a “unique summer field simulation program”. The familiar sight of grassland is enough to improve the mood of the entire herd.
The Ministry of Agriculture of the Russian Federation says that research has shown a link between a cow’s emotional state and its milk production. They stated, “Examples of dairy farms from different countries show that in a calm atmosphere, milk production increases markedly.”
32. What does the underlined word “feasible” probably mean in Paragraph 1?

B. A silent environment helps cows stay healthy.
C. Natural grassland is better for the milk quality.
D. A cow with good moods can produce more milk.
35. What is the main idea of the passage?
A. The emotional difficulties cows face in cold winter months.
B. The benefits of keeping cows in a large farm building in winter.
C. VR headsets improve cows’ emotional well-being and milk production.
D. The development of VR technology for animals living on the grassland.

答案： 32.B 词义猜测题。根据第一段中的“In winter, it can become too cold for cows to stay outside safely, so they are kept in large farm buildings for warmth.”可知，在某些地方只有夏天才能为牛提供开阔的草地区域，即这种做法只有在夏天才可能实现。因此，画线词feasible在这里的意思最接近于选项B“Possible（可能的)”。故选B。
33.B 细节理解题。根据第三段“Reports from a farm in Moscow, Russia—where the VR headsets were first developed by vets—found in 2019 that the cows that used the VR headsets saw a decrease in anxiety and an improved mood. This led to an increase in milk production, which went from 5.8 gallons to 7 gallons per day.”可知，佩戴VR头显的结果是奶牛的产奶量增加了。故选B。
34.D 推理判断题。根据最后一段的内容可知，奶牛的情绪与牛奶产量之间存在联系，再结合全文内容，可以推断出VR头显程序背后的概念是奶牛情绪良好时能够产生更多的牛奶。故选D。
35.C 主旨大意题。根据第一段中的“Being stuck inside is not always pleasant for cattle, and their unhappiness is closely connected to reduce milk production.”和第二段中的“For this reason, some cattle owners have fitted their cows with VR headsets that run a specific program. The program simulates grasslands in summer and was designed specifically for the way that cows get color and light.”以及纵观全文可知，本文主要讲述了VR技术可以改善奶牛的情绪健康，提高产奶量。故选C。
