听力原文: To find out how the name Canada came about we must go back to the 16th century. At that time the French dreamed of discovering and controlling more land, of expanding trade beyond their borders and of spreading their faith across the world. In 1535, Francois I, King of France, ordered a navigator named Jacques Cartier to explore the New World and search for a passage to India.
Cartier first arrived at the Gulf of the St. Lawrence, which he wanted to explore. He did not know what to expect but he hoped that this Gulf was just an arm of the ocean between two islands, if it was, be would soon be on his way to the Far East. So he sailed upstream along the St. Lawrence River. However, instead of reaching Asia he arrived at Quebec or Stadacona, as the Indians called it. It was at this point that the term "Canada" entered the country's history. Apparently the word "Canada" came from an Indian word Kanata, which means community or village. Cartier first used it when he referred to Stadacona or Quebec. What a huge village Canada is!
