D
On 30 December 2024, the tunnelling of Tianshan Shengli Tunnel, the world's longest expressway(高速公路) tunnel, was completed.
As an important section of the Urumqi-Yuli Expressway, this new tunnel with a total length of 22.13 km goes across the Tianshan Mountains—one of the longest mountain ranges in the world—and opens a new pathway to southern Xinjiang. The construction of the tunnel started in April 2020.
When opened to traffic in 2025, it cut travel time through the Tianshan Mountains from 3 hours to about 20 minutes, and the journey from Urumqi to Korla, a city in southern Xinjiang, was shortened from about 7 hours to about 3 hours.
The workers had to overcome many difficulties and be creative in building the tunnel, which is in a high plateau area with complicated geological conditions. They used the construction scheme(方案) of three drifts and four shafts(竖井). Two specially designed tunnel boring machines(硬岩掘进机) were used in the construction of the middle drift to create a working platform for tunnelling.
This is the first time that a tunnel boring machine has been used to build a road tunnel in China. The use of new technologies has cut the construction time of the tunnel from ten years using the traditional drilling method, to just over four years.

【分析】
本题为英语阅读理解题，需通过定位原文对应信息解答细节题、主旨题及态度题。解题思路：先读题干明确问题，再回原文找相关内容，对比选项排除错误答案，最后确定正确选项。
【解析】
50题：细节理解题。根据原文第二段“As an important section of the Urumqi-Yuli Expressway”可知，天山胜利隧道是乌鲁木齐-尉犁高速的一部分，对应B选项；A选项错误，原文提到是“世界最长高速公路隧道”而非“世界最长隧道”；C选项错误，隧道穿越天山而非西藏雪山；D选项错误，通车后穿越隧道仅需约20分钟，故答案为B。
51题：段落主旨题。第三段主要讲述隧道通车后缩短了天山通行时间、乌鲁木齐到库尔勒的行程时间，体现了隧道带来的便利，即好处，对应A选项，故答案为A。
52题：全文主旨题。文章围绕天山胜利隧道的完工展开，介绍了其地位、作用、建设情况等，对应B选项；A选项与天山山脉无关，C选项未突出隧道完工，D选项仅为细节，故答案为B。
53题：作者态度题。全文描述隧道是世界最长高速公路隧道，采用新技术缩短建设时间，克服困难建成，体现了作者对隧道建设的肯定，即积极态度，对应C选项，故答案为C。
