[解析]
（1）B.细节理解题。根据第二段Without these winged helpers，some traveling thousands of miles，coffee farmers would see a 25%drop in crops，a loss of roughly ＄1，066 per acre of coffee.That's important for the ＄26 billion coffee industry﹣including consumers，farmers，and corporations who depend on nature's unpaid labor﹣but the research goes beyond that.（如果没有这些带翅膀的帮手，有些需要长途跋涉数干英里，咖啡农的收成将下降25%，每英亩咖啡的损失约为1066美元。这对价值260亿美元的咖啡产业来说很重要﹣﹣﹣包括依赖大自然无偿劳动的消费者、农民和企业但研究的范围不止于此）可知，新研究关注的是长翅膀的帮手对咖啡树的影响。故选B。
（2）D.细节理解题。根据第四段"Until now，researchers have typically calculated the benefits of nature separately，and then simply added them up，which actually underestimates the benefits biodiversity provides to agriculture and human well being，"says lead expert Alejandra.（"到目前为止，研究人员通常单独计算自然的好处，然后简单地把它们加起来，这实际上低估了生物多样性对农业和人类福祉的好处，"首席专家Alejandra说）可知，维护生物多样性是对咖啡产业的重大推动。故选D。
（3）B.推理判断题。根据第五段"For the experiment，researchers dealt with coffee plants across 30 farms，excluding birds and bees with a combination of large nets and small bags.They tested four key situations：bird activity alone，bee activity alone，no bird or bee activity at all，and finally，a natural environment，where bees and birds were free to pollinate and eat insects like the coffee berry borer，one of the most damaging pests affecting coffee production worldwide.The combined positive effects of birds and bees on fruit set，fruit weight and fruit uniformity﹣key factors in quality and price﹣were greater than their individual effects，the study shows.（在实验中，研究人员在30个农场中处理咖啡植物，不包括鸟类和蜜蜂，同时使用大网和小袋子。他们测试了四种关键情况：只有鸟的活动，只有蜜蜂的活动，没有鸟或蜜蜂的活动，最后，一个自然环境，蜜蜂和鸟类可以自由授粉和吃昆虫，比如咖啡浆果蛀由，这是影响全球咖啡生产的最具破坏性的害虫之一。研究显示，鸟类和蜜蜂对坐果率、果实重量和果实均匀度的综合积极影响﹣﹣﹣这些都是影响质量和价格的关键因素）可知，研究人员通过对比进行测试的。故选B。
（4）C.推理判断题。根据第一段A groundbreaking new study finds that coffee beans are bigger and more plentiful when birds and bees team up to protect and pollinate（授粉）coffee plants.（一项突破性的新研究发现，当鸟类和蜜蜂合作保护咖啡树并为其授粉时，咖啡豆会更大、更丰富）可知，这是一篇新研究。由此推知，文章也许选自报纸的科学版面。A.Advertisement广告；B.Health健康；C.Science科学；D.Travel旅游。故选C。
