China opened the world's tallest bridge on Sunday. It rises 625 meters above the Beipan River in Guizhou Province. It's about twice the height of the Eiffel Tower.
The Huajiang Grand Canyon(峡谷) Bridge stretches 2,890 meters in total length. It is supported by two towers each 262 meters tall.
The project is regarded as a boost(促进) for tourism and economic development in Guizhou Province. Engineers and workers completed load(负荷) testing in late August, and the bridge was opened to traffic on Sept. 28, 2025.

The bridge will connect different communities. It will shorten travel time across the canyon from two hours to two minutes. The bridge also includes some facilities(设施) aimed at visitors, such as a high-speed glass elevator, a glass walkway, and facilities for bungee jumping(蹦极) and other extreme sports attractions. The Huajiang Grand Canyon is nicknamed "the Earth's crack". It is expected to attract millions of visitors in the future.
Engineers and workers faced different challenges when building the bridge, including unpredictable strong winds. Luckily, engineers successfully overcame these difficulties through technological innovations(革新). These innovations made the project get 21 authorized patents(授权专利).
The success of this huge project is an important milestone in the world's bridge engineering. It shows China's great wisdom in building and it also sets a new benchmark(标杆) for building mountain bridges worldwide.

阅读理解C
本文介绍了世界最高大桥——贵州花江峡谷大桥。
1. B 推理判断题。短文第一段提到"It rises 625 meters above the Beipan River ... It's about twice the height of the Eiffel Tower.",即"大桥高度约是埃菲尔铁塔的2倍"。因此埃菲尔铁塔高度约为625 ÷ 2 = 312.5米。
2. C 细节理解题。短文第四段明确提到"It will shorten travel time across the canyon from two hours to two minutes.",说明大桥开通前的通行时间是2小时。
3. B 推理判断题。短文第四段提到"some facilities aimed at visitors, such as a high-speed glass elevator ... and facilities for bungee jumping ... It is expected to attract millions of visitors",由此可推断这些设施是为了吸引游客。
4. B 推理判断题。根据短文第五段可推断专利源于技术革新。
5. B 主旨大意题。全文围绕花江峡谷大桥展开,介绍其开通、高度、长度、建设时间、功能(交通+旅游)及世界意义,核心是介绍这座桥梁。

【分析】
本题是一篇时事类说明文阅读理解，围绕贵州花江峡谷大桥展开。解题时需先通读全文把握核心内容，再针对每道题的题型（细节理解、推理判断、主旨大意），精准定位原文对应信息，结合题干要求分析选项得出答案：第1题需根据大桥与埃菲尔铁塔的高度关系计算；第2题直接定位原文通行时间描述；第3题分析设施设置的目的；第4题定位专利产生的原因；第5题梳理全文核心确定主旨。
【解析】
1. 推理计算：原文第一段提到大桥高625米，是埃菲尔铁塔高度的2倍，因此埃菲尔铁塔高度为625÷2=312.5米，对应选项B。
2. 细节理解：原文第四段明确说明大桥开通后将通行时间从2小时缩短到2分钟，故开通前通行时间为2小时，对应选项C。
3. 推理判断：原文第四段指出这些设施是针对游客设计的，且提到大桥有望吸引数百万游客，说明设置这些设施是为了吸引更多游客，对应选项B。
4. 细节理解：原文第五段提到工程师通过技术创新克服建设困难，这些创新使项目获得21项授权专利，因此专利源于技术革新，对应选项B。
5. 主旨大意：全文围绕花江峡谷大桥展开，介绍其高度、长度、建设情况、功能及世界意义，核心是介绍这座桥梁，对应选项B。
