听力原文： Around the world, about one-hundred-sixty thousand children under age fifteen are found each year to have cancer. The researchers say eighty-four percent of these cases are found in developing countries. They say only ten percent of children with cancer in these countries survive and many more could be saved if their countries had the resources needed to find cancers and treat them. Children from industrial countries like Britain and the United States who develop cancer have a much better chance to survive.
