Today，we have the ability to predict dangerous tornadoes （龍卷風），hurricanes （颶風）winter storms，and floods with more accuracy than ever.We know the areas that are likely to be struck by earthquakes，and the areas that are easily harmed by wildfires，and we can tell hours in advance whether a tsunami （海嘯） will hit our shores.
However，in spite of all the capabilities for advance warnings，Americans are still quite poor at preparing for these disasters.In a 2006 poll carried out by TME Magazine，only 16% percent believed they were"well prepared" for the next one.
A few weeks ago I was listening to NPR （National Public Radio） as I was cooking dinner，and I heard a moving story about a young boy，Noah Stewart，who lived through a tornado that hit his Alabama home.
Noah was sucked up into the tornado and then dropped.He landed on his head first，a fall of such force that，under normal conditions，would have killed him.However，be survived because his mother made a quick decision to put a baseball helmet on his head right before the tornado hit.Noah was unhurt in the storm.But the helmet cracked （破裂} down the middle.
The CDC states that they can't say whether helmets save lives during a tornado impact （撞擊） .However，it still seems wise for anyone in a tornado-prone （可能的） area to keep several helmets at the ready.Any added protection is going to increase your chance of survival，and as Noah's story clearly shows，helmets can save lives.
You don't have to buy new helmets- picking up used bicycle，football，or baseball helmets at economical stores and garage sales （舊貨市場） can save money and keep your family protected.
However，it's necessary that you keep these helmets in an easily reachable place；they should not be used for any other purpose，as they may be misplaced.Remember，when a tornado hits，you might only have minutes- or even seconds- -to find shelter.You don't want to be running around the house，searching for those helmets.

1． To prepare for-real-life emergencies，rescue teams must practice.They practice putting on ice suits，working with ropes，and using hand signals to communicate.And once the lake freezes，then practice ice rescue.
On a training day，a firefighter puts on his ice suit.He then pushes air out of the ice suit.If not，the trapped air bubble could make him float.He walks out onto frozen lake to play the role of the "victim（受害者）".He shakes，not from cold，but worries about not knowing when he'll fall through!His first several steps feel solid.The ice seems thick.But 28 steps in：Crack!Water begins to come in through the ice.He slows down.At 31 steps-Plunk!He falls through the ice.He keeps him mouth shut so he doesn't swallow any water.It's time for him to pretend to be a victim，calling for help and struggling in the lake.
Two more firefighters，attached to the onshore team with ropes，walk onto the lake.They stay on different parts of the ice in case it breaks，both carrying protective equipment like a belt or a board.Meanwhile，onshore team members，wearing life vests，talk to the "victim" to keep him calm.Near the ice hole，a rescuer drops to her belly and moves slowly.The second rescuer rolls.Both methods spread out the weight so they don't also fall through the ice.
The firefighter with the board explains that they're there to help.She hands the board to the victim and tells him to catch it.The second firefighter enters the water and ties the belt securely to the victim.He gives a signal and the onshore members pulls the rope.As the rope tightens，the rescuer lifts the victim's legs so he's on his belly.Together，they sail across the ice.
Once they're on land，firefighters exchange roles.When every firefighter has had a turn at rescuing and playing "victim"，they all put on warm，dry clothes and head back to the station for hot chocolate.
（1）Why does the "victim" push air out of his ice suit before entering water？
