The local people of La Gomera can carry on conversations by whistling（吹口哨） from far away． For face﹣to﹣face conversations，they Spanish．But when they need to speak over a distance（距离），they whistle．

   La Gomera is a small island．This island is almost shaped like a circle．It is very mountainous．Walking from one place to another may be a slow and difficult job． That is why whistling is so useful to the local people． A message can easily be whistled over a couple of miles， while to travel that same distance on foot might take an hour．

   A good whistler can be heard and understood five miles away．His whistling can be farther away when it is windless． It is said that the record is about nine miles．Anyone who a top whistler will agree that this record is quite possible．

   A whistle travels farther than a shout， and is easier to understand． When a person shouts， he cannot pronounce his words well． But if a whistle is heard， it will be heard clearly
