          • 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?

            A.To walk in the water.
            B.To sink beneath the ice.
            C.To float on the surface.
            D.To approach firefighters.
            (2)What shouldn't the rescue members do during the practice?

            A.Stay apart on the ice surface.
            B.Walk as fast as possible on ice.
            C.Be careful in their each step.
            D.Carry protective equipment.
            (3)What can we learn from the text?

            A.Ice rescue only requires excellent individual skills.
            B.The rescue group perform such rescue practice daily.
            C.The firefighters take turns to play the part of "victim".
            D.It is unnecessary to talk to the "victim" during the rescue.
            (4)What is the best title for the passage?

            A.Rescue on the ice
            B.Practice on ice land
            C.Ways of saving people
            D.Bravery of firefighters
