A quick walk onto a frozen pond could have been a disaster for these two boys.
   Cruz Genet，11，and Anthony Skopick，10，couldn't agree.Were the birds out on the ice ducks or geese？There was only one way to find out.So on a cold January evening last year，the two friends walked onto the frozen pond near their homes to get a better look.
   First，they threw a rock onto the ice to test it.Convinced the ice would hold their weight，Anthony took a few steps，and then he crashed through the seemingly frozen surface. "There was no sound，no crack，" he told the reporter. "I just fell through instantly."
   Cruz rushed to help his frightened friend.And the pond swallowed him，too.Cruz managed to lift himself out of the water and onto a more solid section.He then cautiously worked his way toward Anthony，but he fell in the pond again.This time，he couldn't get out.
   The boys were in icy cold water and quickly losing feeling in their limbs （四肢）.Cruz was sure that he was going to die.
   Anthony's older sister had seen the boys fall through the ice and started screaming for help.John Lavin，a neighbor driving nearby on his way to the store，heard jye.air.He quickly pulled over.Seeing the boys，he grabbed a nearby buoy（浮標），kicked off his shoes，and ran into the water.Lavin made his way to Cruz and Anthony and dragged them back to land.They were taken to hospital，where doctors discovered that their five-minute stay in the water had lowered their body temperature nearly ten degrees.
   Fortunately，the boys have fully recovered，though they are still a little awestruck （敬畏的）by their fearless neighbor. "Just to think，" says Cruz， "if he hadn't been there，I could have died."
