Shipping companies are trying to make ocean travel cleaner. One of the world's largest shipping companies now plans to put a special sail on one of its cargo ships.
one of the world's largest= 全球最大型的公司之一
Cargo ships move large amounts of goods across the sea. Adding a sail allows the ship to use wind power. This helps the ship burn less fuel and cut carbon emissions.
allows the ship to= 使船隻能夠做某件事
This new project is the latest in a small but growing number of cleaner cargo ships. More companies are turning back to wind power to help make ocean shipping cleaner.
