     We could all see the Murray Uiver slowly moving back, but now all the water was gone. I couldn't believe

that the Murray had dried up, not one drop of water left.

     One morning I went down to the river to try and catch some fish when I saw my boat high and dry (搁浅)

on the bank. I rushed down the river and saw all mud-no water. The fish were just lying there, dying. I looked

up to see if my friend was there. There was the nest but no eagle (鹰). I called out to her with my special

whistle which I made out of steel.

     Suddenly a big shadow came over to me and the eagle landed in her nest and gave her young the food she

was out getting while I whistled. But then I suddenly noticed she was getting thinner and had a bit of sheep's

wool in the side of her talon (利爪). It was deadly quiet by the river bank, except for some sound from my dog.

And also I couldn't see one native animal or bird.

     When I walked inside the kitchen, Mum and Dad had sad looks on their faces. "It's time for us to move,

Son, because the river can no longer provide for (养活) us," said Dad. I ran out of the kitchen door with tears

in my eyes, and down to the river bank, to my favorite spot. I said goodbye to my eagle, crying.

     When it was time to go, I saw my eagle fly up into the air with her chicks in her talons, going away to try

and find another home, just like us.
