          Canada Geese (鹅) are large blue and white birds. When autumn arrives, they have to fly south where the

weather is warmer. The winters are so cold in Canada that the birds died if they stay there. Here's a story about

some Canada Geese.

         (A) When he arrived back home, Bill found the geese waiting for him. They had found their way home

without him!

         (B) He had a small plane and he decided to teach them to follow him. Last summer, he went on shorts

trips in his plane and the young geese flew after him.

         (C) This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia

(弗吉尼亚) to get them. He looked for them for two weeks but he couldn't find them. So he had to fly home. 

        (D) Bill Lishman is a farmer who loves birds. Last spring, he found sixteen young Canada Geese on his

farm. They had lost their parents. Bill thought, "These young birds won't know what to do in the autumn. I will

do something to help them."

       (E) When it became cold last autumn, Bill flew to Virginia in the United States, 600 miles south of his home

in Canada. The geese followed him all the way. Bill left the geese in Virginia and returned home.
