阅读理解。 Venice is an attractive city in Italy. Tourists throughout the world love traveling to Venice. But sometimes you'll have such strange experiences. One moment you walk across the Rialto Bridge, and there's nothing special. Unfortunately, when you come back to the bridge an hour later, it's underwater and everyone's wearing rain boots. That's just the way it has always been, which may be considered seriously by Italian government. Before the sea comes to Venice, the government has decided to build the MOSE gates. Actually (实际上), there were many kinds of gates that were built to stop the floods, but all the gates were just built on the ground. Besides, the flooding was becoming worse. Industrial (工业的) factories built nearby on the mainland also made the condition get worse, causing the city to sink about 0.75 feet in the 20th century. So the Italian government asked some of Italy's biggest construction and engineering companies to build the MOSE project, which was planned to be built under the sea water to stop floods. Now the government are using 3 000 people and expect to spend nearly five billion euros (欧元) on it. The MOSE gates are being built at the inlets (海湾). Each MOSE gate is 197 feet long, 28.5 to 37 feel tall, and weight up to 22 tons. It's nearly the size of a 20-story building. Before the gates are in use, under the sea full of water. When the flood comes, the water in the gates will be poured out, and then the gates will be filled with air. So the gates can go up with the sea water. Once they're in the right place, they will stop the sea water pouring into Venice. These gates will be able to deal with floods up to 10 feet, and as long as the sea level (平面) rises no more than two feet in the next 100 years, the MOSE will work as expected. The MOSE project is now two-thirds done. The head engineer, Giovanni Cecconi, said, 'This is a war. During the war, it's not important that you win. It's important that you're alive. We've alive.' Anyway, this project is saving Venice from falling. 1. The underlined word 'construction' in the passage means '_______' in Chinese. A. 建筑 B. 农业 C. 交通 2.
