Where we live，on the eastern shore of Maryland，the gentle waters run in and out like fingers slimming at the tips.
The Canada geese know this place，as do the white swans and the ducks. In autumn，they come home for the winter. Once or twice each year，snow and frozen rain move into the area. When this happens，if the river is at its narrowest，there is a freeze which hardens the water to ice.
One morning，a friend of mine set the breakfast table beside the huge window，which overlooked the Tred Avon River. Suddenly she leaned forward and cried out，“There is a goose out there.”
We saw the figure of a large Canada goose，very still，its wings folded tight to its sides，its feet frozen into the ice.
Then from the dark skies，she saw a line of swans. They floated from the top of the sky downward and at last landed on the ice. My friend was on her feet now，with one hand against her mouth，unbelieving. As the swans surrounded the frozen goose，she feared that life it still had might be pecked(啄) out by those great swan bills.
Instead，those bills began to work on the ice. The long necks were lifted and curved down，again and again. It went on for a long time. At last，the goose’s head was lifted. Its body was pulled. Then the goose was free and stood on the ice. And the swans stood in the air watching. Then，as if it had cried，“I cannot fly.” Four of the swans came down around it. Their powerful beaks chipped off the ice held in the feathers. Slowly，the goose spread its wings as far as they would go，and moved slowly into the sky.
This is a true story. I just think of it in the bad moment，and from it comes only one hopeful question：If so for birds，why not for man？

(答案→)A 解析：本文讲述了在结冰的湖面上，一只天鹅陷在冰上无法动弹。它的一些同伴落在冰面之上帮助它脱离了困境。由此想象到既然动物都能这样相互帮助，我们人类为什么就不能呢？【小题1】A 主旨大意题。根据文章最后一段This is a true story. I just think of it in the bad moment，and from it comes only one hopeful question：If so for birds，why not for man？可知本文呼吁人们要像大雁一样相互帮助以克服困难。故A正确，【小题2】B 细节题。根据文章第三段We saw the figure of a large Canada goose，very still，its wings folded tight to its sides，its feet frozen into the ice.可知这只天鹅陷在了结冰的湖面之上，无法动弹。故B正确。【小题3】.D 细节题。根据第五段As the swans surrounded the frozen goose，she feared that life it still had might be pecked(啄) out by those great swan bills.可知朋友很担心这只天鹅会被同伴啄死。故D正确。【小题4】A 细节题。根据文章倒数第二段倒数第二句Four of the swans came down around it.
