The world is not hungry，but it’s thirsty.   1  while we say we are short of water.Why？Because about 97% of water on the earth is sea water which we can‘t drink or use for watering plants directly.Man can only drink and use the 3% of water that comes from rivers and lakes.   2  ，because some of it has been polluted.
　　Now more water is needed.The problem is how we can avoid a serious water shortage in the future.  3 Scientists are making study in this field.Today，In most large cities water is used only once and then runs to the sea or rivers.but it can be used again.Even if every large city reused its water，the water will still not be enough. 4 .
　　The sea seems to give us the best answer.There is a lot of water in the sea.All that needs to be get the salt out of the sea water.This will be expensive，but it has already been used in many parts of the world.   6 So you see，if we can find out a way，we’ll be in no danger of drying up.

Once　upon　a　time,　a　young　man　was　standing　in　the　middle　of　the　town　announcing　that　he　had　the　most　beautiful　heart　in　the　world.　A　large　crowd　gathered,　and　they　al　praised　his　heart　for　it　was　perfect.
Suddenly,　an　old　man　appeared　and　said,　“Why　,your　heart　is　not　as　beautiful　as　mine.”
The　old　man’s　heart　was　ful　of　scars（伤疤）.　Some　pieces　of　his　heart　were　removed　and　some　pieces　from　other　people　were　put　in,　but　they　didn’t　fit　quite　right.　So　there　were　several　jagged（锯齿状的）edges.　In　fact,　there　were　stil　some　holes　in　his　heart　where　the　pieces　were　missing.
The　 young　 man　 laughed,“Comparing　yours　with　mine,　mine　is　perfect　and　yours　is　a　mess.”
“Yes,”said　the　old　man.　“But,　every　scar　shows　that　I　took　out　a　piece　of　my　heart　and　gave　it　to　a　person,　and　often　he　gave　me　a　piece　of　his　heart　in　return.”
“Why　do　you　have　some　jagged　edges　in　your　heart?”asked　the　young　man.“Because　the　shapes　of　the　pieces　weren’t　the　same.”“Then　the　holes?”“Sometimes　I　gave　pieces　of　my　heart　away,　and　the　other　person　hasn’t　given　back　a　piece　of　his,　so　… but　I　don’t　care.”“How　come?”“They　remind　me　of　the　love　we　shared.”
The　young　man　was　deeply　moved.　He　walked　up　to　the　old　man,　took　a　piece　of　his　heart　out　and　gave　it　to　the　old　man.
The　old　man　placed　it　in　his　heart,　then　took　a　piece　from　his　old　scarred　heart　and　placed　it　in　the　wound（伤口）in　the　young　man’s　heart.　It　fitted,　but　not　perfectly,　as　there　were　some　jagged　edges.
The　young　man　looked　at　his　heart,　not　perfect　any　more　but　more　beautiful　than　ever.
How　sad　it　must　be　to　go　through　 life　 with　 a　 whole　untouched　heart!
