Tens of thousands of baby penguins (企鹅) face starvation after two giant icebergs broke off the Antarctic ice sheet and blocked their parents' way to feeding areas.
Adelie and emperor penguins nesting on the Ross Island are now forced to walk long distances over the icebergs to obtain food for their chicks, born during the November-December breeding (繁育) season.
“The penguins are having to walk 50 km further than usual to reach the sea,” said Dean Peterson. The flightless birds travel on land at just one to two km per hour.
The problem could halve (平分) the chick survival (存活) rate at the three Adelie penguin colonies on Ross Islandestimated at 130,000 breeding pairs. In all Antarotica, there is an estimated three million Adelie penguin breeding pairs.
Around 12,000 breeding pairs of emperor penguins, the largest penguin species at up to four feet tall, are also affected.
The icebergs broke from the vast Ross Ice shelf, south of New Zealand, in March 2000 and are now sandwiched between Ross Island and Franklin Island, 93 miles to the north.
Scientist Peterson estimated that penguins were taking days to make the round trip to the sea to fish, and then back to their nests to regurgitate (反刍) food for their chicks.
“At that point they were quite tired and probably don't have much to regurgitate,” he said. Penguins already have long odds on reaching adulthood, with only 10 percent surviving beyond adolescence(青春期).
“We are probably looking at halving that againwe are sitting down at maybe the five percent rate,” Peterson said, adding some penguins already appeared to be leaving the Ross Island to breed elsewhere.
Penguins come ashore to breed and then take it in turns to leave the nest to fetch fish and other sea food to feed their young.
Researchers say large blocks of the Antarctic ice sheet are breaking off for several reasons, including global warming.
Emperor and Adelie penguins are limited to Antarctica. The emperors weigh up to 66 pounds while Adelie penguins are much smaller, weighing around 11 pounds.
1.After the long trip, the mother penguins ________.
[ ]
A.are too tired to feed their young
B.can't bring up much to feed their young
C.are too hungry themselves
D.have already ate up all the food
2.The underlined phrase “have long odds on” probably means ________.
[ ]
3.From what scientist Peterson said, we can infer that ________.
[ ]
A.the survival rate of penguins is dropping
B.there are few penguins left on Ross Island
C.the present situation can cause the penguins to die out
D.penguins usually have a high survival rate
4.Which of the following best supports the main idea of the passage?
[ ]
A.Global warming caused the icebergs to break off.
B.The long trip made mother penguins too tired to feed their young.
C.The change of weather affects penguins.
D.Broken icebergs endanger penguin chicks.

Tens of Thousands of couples across the United States are racing to get marred by April 30. This is the result of a new law that makes illegal(非法的) immigrants(移民) legal if they marry by then.
The law has sent marriage rising by 50 percent to 300 this year in immigrant-rich Los Angeles, Houston and New York. The new law, passed in the last days of the Clinton administration(任期), contains a large number of measures to help immigrants and their loved ones become legal.
Critics say it also brings many marriage fraud(诈骗). A key aspect allows immigrants to look for houses while remaining in the USA-if they are married to a citizen or legal resident and hand in applications by April 30After the date, applicants will have to return to their native countries to deal with their paperwork-a requirement that could take as long as 10 years.
Demand for marriage licenses in Manhattan this year jumped from 100 a day to more than 300. The Los Angeles County registrar(户籍员)-recorder's office supplied 12,997 marriage license during January and February, a 59 percent increase over last year.
Critics say the new law encourages false marriage. There are a lot of marriage frauds as people rush to make use of this window. In the past cases citizens or legal residents were paid US 10,000 or more to marry illegal immigrants in which immigration is concluded may be investigated for as long as two years after the vows.
“It's not worth the risk to attempt an illegal marriage,” says INS spokesman Bill Strassberger.
