Where people cannot safely go, such as in burning buildings, on fallen structures, or on top of windy industrial towers, Swiss drones are being used. Switzerland is using these flying machines not only to watch but also to touch and change their surroundings.

These drone advances are useful in difficult places. FireDrone, started by Fabian Wiesemüller and others, has made a drone that can be “used in a burning fire”. This technology lets firefighters fly into burning houses to look for missing people or check very hot areas in steel factories and cement plants.

For disaster help that needs long-distance carrying, Dufour Aerospace, led by CEO Sascha Hardegger, created wings that can change position. This turns drones into small airplanes after taking off straight up. This system helps to carry important goods and tools to disaster places where roads cannot be used.

Thomas Zurbuchen, who leads ETH Zurich’s special Geolab, explains the country’s special “good position.” “We are small,” he says. “This means we can do things that others cannot. For example, we can study a whole mountain and fly drones above it.” The Geolab puts together information from drones, satellites, and ground sensors to better guess when natural disasters may happen. Switzerland’s small size, along with its strong computing power and research knowledge, makes it a perfect testing place. “We can bring everything together... where we then not only solve problems here, but also use the solutions around the world,” Zurbuchen says.

While military uses get more news in other countries, Swiss companies have found an important place in everyday uses, including farming and disaster help. This clear direction is supported by a strong money system, with about 60 percent of Swiss investment for new businesses going into new technology companies. From EPFL labs to world industrial places, Swiss drones show how gathered special knowledge can solve serious real-world problems.

1.1. What is the main function of Swiss drones described in Paragraph 1?

A Observing environments only.

B Replacing human workers completely.

C Operating in dangerous situations.

D Flying faster than other drones.

解析：选C。C细节理解题。第一段明确指出，瑞士无人机被用于“人们无法安全前往的地方（Where people cannot safely go）”，例如燃烧的建筑、倒塌的结构等。其功能不仅是“观察（watch）”，还能“接触和改变周围环境（touch and change their surroundings）”。C项“在危险情况下运行”准确概括了这一核心功能。A项错在“only”，因为原文提到其功能不止观察；B项“完全取代”和D项“飞得更快”均未在文中提及。故选C。

2.2.What is the special feature of the drone wings developed by Dufour Aerospace?

A Changing shape after takeoff.

B Increasing flight speed greatly.

C Reducing energy consumption.

D Carrying more people.

解析：选A。A细节理解题。第三段描述Dufour Aerospace公司研发了“可以改变位置的机翼（wings that can change position）”，这使得无人机在垂直起飞后“转变为小型飞机（turns drones into small airplanes after taking off straight up）”。A项“起飞后改变形状”准确地捕捉了这一“变形”功能的核心。B项“大幅提升速度”、C项“减少能耗”和D项“承载更多人”均不是本段所描述的特点。故选A。

3.3.According to Thomas Zurbuchen, what makes Switzerland particularly suitable for testing?

A Its vast territory for extensive experiments.

B Its manageable size as a complete test bed.

C Its focus on commercial applications.

D Its isolation from global networks.

解析：选B。B推理判断题。Thomas Zurbuchen首先明确指出瑞士的优势在于“We are small（我们国家规模小）”，并紧接着用具体事例解释：“For example, we can study a whole mountain and fly drones above it.（例如，我们可以研究一整座山脉并在其上方飞行无人机）”。后文进一步总结：“Switzerland’s small size... makes it a perfect testing place.（瑞士的小规模…使其成为一个完美的测试场所）”。由此可以推断，瑞士的国土规模小且完整，使得研究人员能够将整个国家或其典型地貌（如一座山）作为一个统一的、可管理的“完整试验场”来进行全面研究和技术测试。这种“小而全”的特性是其实验效率高的地理基础。选项A“广阔领土”与段首强调的“规模小”直接矛盾；选项C“商业应用”与本段的研究导向不符；选项D“脱离全球网络”在文中完全未提及，且与“整合多方数据”的描述相悖。故选B。

4.4.Which field has Switzerland prioritized for its drone technology development?

A Military and defense contracts.

B Civilian and emergency applications.

C Media and entertainment industry.

D Scientific research in space.

解析：选B。B细节理解题。第五段开篇通过对比指出：“虽然军事用途在其他国家获得更多新闻关注(While military uses get more news in other countries)，但瑞士公司在日常应用中找到重要位置，包括农业和灾难救援(Swiss companies have found an important place in everyday uses, including farming and disaster help)”。B项“民用和应急救援应用”准确地概括了瑞士优先发展的方向。A项恰是其他国家更侧重的领域；C项“媒体娱乐业”和D项“太空科研”均非本段强调的优先领域。故选B。
