 It snowed again. My seventh Christmas was round the corner. I dreamed of getting the present from Father Christmas until my elder sister dropped the bomb, “There is no Father Christmas.”

  I ran to my grandmother’s house, for she always told the truth. Grandma was at home. I told __11___ everything. “No Father Christmas?” she was a little ___12____. “Don’t believe it. Put on your coat, and let’s go.”

  “Go? Where, Grandma?” I asked.

  “Kerby’s Store.”

  As we walked through its doors, Grandma handed me ten dollars and said, “Take the __13___ and buy something for someone who needs it. I’ll wait for in the car.” Then she turned and walked out of the Kerby’s.

  For a few seconds I just stood there, holding the money, wondering ___14___ to buy, and who to buy it for.

  I thought of ___15___ I knew: my family, my friends, my neighbors … I suddenly thought of Bobbie Decker, a __16___ with bad and messy hair. He sat right behind me ___17____ Mrs. Pollack’s class.

  Bobbie ___18___ went to any party during the winter. His mother always wrote a note, telling the teacher that he had a cough, ___19____ we all knew that he didn’t have a cough, and he didn’t have a coat. I decided to buy Bobbie a red warm coat ___20____ he would like.

  That evening, Grandma helped me wrap the coat in Christmas paper and ribbons, and ___21___ “To Bobbie, From Father Christmas” on it. Grandma told me Father Christmas never let people know that he ___22___ them. Then she drove me over to Bobbie’s house, telling that I was helping Father Christmas ____23___ the presents.

Grandma parked the car along the street, and we hid behind the trees near Bobbie’s house. Then Grandma said to me, “All right, Father Christmas, get going.”

  I took a deep breath, rushed to his front door, put the present down. ____24___ the door, rang the doorbell and flew back to the safety of the ____25_____ and Grandma. We waited breathlessly in the dark for the front door to open. Finally it did, and there stood Bobbie.

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.
