Trees are useful to man in three very important ways：they provide him with wood and other products；they give him shade；they help to prevent drought and floods．
Unfortunately，in many parts of the world，man has not realized that the third of these services is the most important．To make money from the trees，he has cut them down in large numbers，only to find that without them he has lost the best friends he had．
Two thousand years ago，a rich and powerful country cut down its trees to build warships，with which to gain itself an empire（帝國(guó)）．It gained the empire，but since the trees were cut down，its soil became hard and poor．When the empire fell to pieces，the home country found itself faced by floods and hunger．
Even where a government realizes the importance of an enough supply of trees，it is difficult for it to let the villagers see this．The villagers want wood to cook their food with，and they can earn money by selling wood to the townsmen．They are usually too lazy or too careless to plant and look after new trees．So，unless the government has a good system of control or can educate the villagers，the forests will not get protected．
This does not only mean that the villagers' sons and grandsons will have fewer trees．The results are even more serious．Where there are trees，their roots break the soil up，allowing the rain to sink in，which makes the soil stick together and prevents it being washed away easily．Where there are no trees，the rain falls on hard ground and flows away on the surface，causing floods and carrying away with it the rich top-soil，in which crops grow so well．When all the top-soil is gone，nothing remains but worthless desert．

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.
