What the man in his kindness and haste did not understand was that the restricting(限制的) 16 and the struggle required for the butterfly to 17 the tiny opening were nature’s way of forcing fluid(液体) from the body of the butterfly into its wings so that it would be ready for flight once it achieved its 18 from the cocoon.

Ⅱ.阅读理解
In recent years，much of the sea ice that polar bears use as a hunting platform for seal meals has melted，forcing some bears—particularly young males—farther north or onto land，where they are not as skilled at hunting.When stuck on land for months，a polar bear typically is forced to survive on its own fat reserves.
The bears were listed earlier this year as a threatened species under the U.S.Endangered Species Act as populations have declined.Meanwhile，snow geese are booming near the western Hudson Bay，and there are in fact too many of them.Their eggs can be a good food source.The geese nest on tundra(冻原，苔原) that some bears have retreated to.
“O ver 40 years，six subadult(接近成年的) male bears were seen among snow goose nests，and four of them were sighted after the year 2000，” says Robert Rockwell.“I’ve seen a subadult male eat goose eggs whole or press its nose against the shell，break it，and eat the c ontents.”
Ice is melting，on average,0.72 days earlier each year in the region studied.Snow geese are hatching eggs about 0.16 days sooner each year，according to Rockwell and his graduate
student Linda Gormezano.Current trends indicate that the arrival of polar bears will correspond to the average hatching period in 3.6 years，and egg consumption could bee a viable option，which the researcher concluded in a statement released today.
A polar bear，the largest land carnivore(食肉动物)，would need to consume the eggs of 43 nests to replace the energy gained from the average day of hunting seals，but Rockwell and his colleagues figure that while many polar bears may starve in ing years，the resourceful animals just might survive disappearance.
Polar bears survived a warm period about 125,000 years ago，when sea level was 12 to 18 feet higher than it is now and trees lived above the Arctic Circle，the scientists point out.“They’ve been through the warm period before，” Rockwell said.
The polar bears’ potential movement to a di et of more eggs brought to mind a quote by Ilkoo Angutikjuak，an Inuit who lives in the Canadian province of Nunavut，in the February xx issue of Natural History magazine，Rockwell said.Angutikjuak said：“The animals will adapt.I’ve heard that because they dep end on sea ice，polar bears will disappear，but I don’t believe it.They are very adaptable.As the sea ice changes，polar bears might get skinnier and some might die，but I don’t think they will disappear.”
21.What can we infer about the polar bears from the passage?
A.They have a strong ability to survive.
B.They tend to withdraw from the tundra.
C.Their hunting skills have declined sharply.
D.Their main food source is goose eggs now.
22.What does the underlined word “viable” in Paragraph 4 mean?
A.Challenging.
B.Practical.
C.Destructive.
D.Outdated.
23.Which of the following statements does Rockwell agree with?
A.Goose eggs are adequate for polar bears.
B.Polar bears’ food variety is relatively limited.
C.Polar bears might adapt to the global warming.
D.Many polar bears will starve to death in future.
24.What’s the passage mainly talking about?
A.Polar bears pose a major threat to the geese.
B.Polar bears can live in harmony with the geese.
C.Polar bears are disappearing due to climate change.
D.The geese probably could save polar bears from extinction.

故选A。

] 22.B [词义猜测题。

根据画线词上文的内容，尤其是“Current trends indicate that the arrival of polar bears will correspond to the average hat ching period in 3.6 years”可知，北极熊的出生周期将与雪鹅的平均孵化周期在3.6年后达到一致，故北极熊将雪鹅蛋作为新的食物来源是可行的。

B项practical(计划方法等)切实可行的，符合题意。

]
23.C [细节理解题。

根据最后三段的内容可知，尤其是“Rockwell and his colleagues figure that while many polar bears may starve in ing years，the resourceful animals just might survive disappearance”，“They’ve been through the warm period before”和“The animals will adapt.”可知，北极熊不会灭亡，它们可能会适应全球变暖的情况。

故选C。

]
24.D [主旨大意题。

根据全文内容可知，本文主要讲的是随着气候变暖，北极熊赖以生存的海冰逐渐融化，这使得它们的生存面临着巨大的威胁，但是它们为自己找到了一种新食物——雪鹅蛋，这或许可以用来拯救它们并使其摆脱灭绝的危机。

故D项最能概括文章主旨。
