阅读理解。 We could all see the Murray River 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 support 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. 1.
