Speed is very important in avalanche （雪崩）rescues.There will be narrow chances to escape if a skier is buried for 30 minutes or more.Now that 30 minutes can mean the difference between life and death for a skier lost on a snowy mountain，most people would depend on lifesaving dogs.
Noble works as a rescue team member in a vacation land，California.He tells us，"Dogs run fastest when an accident happens." His partner Wylee，a lifesaving dog，can search an accident scene the size of a football field.It only needs 5 to 10 minutes.However，5 rescue team members have to spend a couple of hours in the same area.
Apart from its excellent speed，Noble chooses Wylee as his partner partly because it weighs only about half what other kinds of dogs weigh.Rescue team members have to carry their dogs to search sites in addition to carrying 60 pound backpacks with food，water and other equipment.The dogs need the lift so that don't get tired before they start working.
There aren't adequate data on how often dogs take part in avalanche searches or how often they are able to help local people in danger.But the dogs don't save that many people.That's because there aren't that many to save.A quarter of people in danger die from serious injuries before the snow stops moving.Of those buried who weren't killed by injuries，half die within 20 minutes.If there is a chance of rescue，though，the dogs also cut search time for the remains.
Erica Mueller，a famous director，wanted to see how the lifesaving dogs worked，so she volunteered to spend part of an hour in a roomy snow cave waiting to be found.She was armed with a radio and was wearing several layers to stay warm.After being rescued by Wylee，she said，"I can't talk like a survivor，but it was definitely a cool way to see how well trained those dogs are."發(fā)布：2024/12/18 5:30:1組卷：6引用：2難度：0.42390．There is a
