13.A group of swimmers has described how a group of dolphins (海豚) protected them from a group of white sharks (食人鲨)off the coast of New Zealand.The lifeguards were on a training swim when they came across a group of great white sharks before the dolphins raced in to help.The swimmers were surrounded by the dolphins for forty minutes before they were able to make them safety back to the beach.It was an uncomfortable experience as they were circled by a group of white sharks,which came within a couple of meters of them.Lifeguard Rob Howes was in the water with two colleagues (同事) and his teenage daughter.He said around half a dozen dolphins suddenly appeared and forced them to gather together.The mammals (哺乳动物) swam in tight circles to create a protective wall between the white sharks and the lifeguards as the great white sharks were under the surface.
