【题目】 The world’s longest cross-sea bridge——the 55-km-long Hong Kong-Zhuhai-Macao Bridge （HZMB） opened on Oct 24, 2018. The Guardian described it as one of the “seven wonders of the modern world”.
Construction（建筑工程）on the HZMB began in 2009 and cost about 120 billion yuan. The bridge links Hong Kong and Macao to the Chinese mainland city of Zhuhai.
The HZMB is unique in many ways. It’s designed to have a service life of 120 years, 20 years longer than most bridges.
And it’s not just a bridge, but also part tunnel（隧道）and part island. In one section, the bridge turns into a 6.7-km undersea tunnel that passes through two man-made islands. The tunnel is the world’s longest undersea tunnel for road traffic, allowing large ships to continue passing through the sea area above the tunnel.
The bridge’s engineers had to consider many environmental factors in order to protect the surrounding（周围的）environment while building the bridge. Chinese white dolphins, an endangered species that lives in the area, were a particular concern（关注）.
The HZMB will make it much more convenient to travel between the three areas it connects. It will shorten the travel time from Hong Kong to Zhuhai from four hours to about 45 minutes.
By drawing local cities and regions closer together, the bridge will help in the area’s development. It is expected to drive the economic（经济的）development of Hong Kong, Macao and nine Guangdong cities.

【解析】
文章大意：文章主要介绍了港珠澳大桥的相关事情，如桥的特点，特殊的设计，设计时候注意事项等。
【1】细节理解题。根据文章第一段中的“The world’s longest cross-sea bridge——the 55-km-long Hong Kong-Zhuhai-Macao Bridge （HZMB） opened on Oct 24, 2018”“世界上最长的跨海大桥——55公里长的香港珠海澳门大桥（HZMB）于2018年10月24日开通”可知，港珠澳大桥是在10月24日开通，故选A。
【2】细节理解题。根据文章第一段中“The world’s longest cross-sea bridge——the 55-km-long Hong Kong-Zhuhai-Macao Bridge （HZMB） opened on Oct 24, 2018”“世界上最长的跨海大桥——55公里长的香港珠海澳门大桥（HZMB）于2018年10月24日开通”和第二段中的“Construction（建筑工程）on the HZMB began in 2009”“HZMB于2009年开工建设”可知，港珠澳大桥于2009年开建，2018年建成，所以建造这座桥花费了9年的时间，故选C。
【3】细节理解题。根据文章第五段中的“The bridge’s engineers had to consider many environmental factors in order to protect the surrounding（周围的）environment while building the bridge”“建桥时，为了保护周围的环境，桥梁的工程师们不得不考虑许多环境因素”可知，桥梁的工程师们考虑了许多环境因素，是为了保护环境，故选B。
【4】细节理解题。根据文章第一段中的“The Guardian described it as one of the “seven wonders of the modern world”“《卫报》称之为“现代世界七大奇迹”之一”可知，港珠澳大桥是世界七大奇迹之一，A说法中港珠澳大桥是世界上第六大奇迹说法是错误的；根据文章第二段中的“Construction（建筑工程）on the HZMB began in 2009 and cost about 120 billion yuan”“港珠澳大桥于2009年开工建设，耗资约1200亿元”可知，港珠澳大桥耗资约1200亿元，所以B说法中港珠澳大桥耗资约120亿元是错误的；根据文章第一段中“The world’s longest cross-sea bridge——the 55-km-long Hong Kong-Zhuhai-Macao Bridge （HZMB） opened on Oct 24, 2018”“世界上最长的跨海大桥——55公里长的香港珠海澳门大桥（HZMB）于2018年10月24日开通”可知，港珠澳大桥是世界上最长的跨海大桥，所以C说法是正确的；根据文章第三段中的“It’s designed to have a service life of 120 years, 20 years longer than most bridges”“它的设计使用寿命为120年，比大多数桥梁长20年”可知，港珠澳大桥的使用寿命是120年，所以D中港珠澳大桥能使用100年说法是错误的，故选C。
【5】主旨大意题。通读第四段可知，文章第四段主要讲的是怎样建造港珠澳大桥，故选C。
