（二）Venice is a city in Italy. It sits on some islands.Tourists like to see Venice’s buildings, bridges, and canals.That may not be possible in the future, though. That isbecause the city is sinking. The land under Venice isgetting smaller, and the Earth’s plates under that keepmoving. Venice’s boats are causing problems, too. Mostboats have gas engines and can go fast. They make waves,which destroy the buildings over time. Now, there is a newboat on the market. It uses electricity. It has wings underthe boat. When it starts to go fast, it rises from the water.This means it makes fewer big waves.
