    Scientists have recently discovered a major habitat where live more than 1.5 million Adelie penguins(企鹅）near the Antarctic Peninsula. Based on direct ground counts and computer counts, the researchers found a total of 751,527 pairs of Adelie penguins on the Danger Islands in the Weddell Sea on the east side of the Antarctic Peninsula. The Adelie penguins discovered here is more than the rest in the other places of Antarctic Peninsula, which was published in the journal Scientific Reports.

Moreover, the number represents the first complete census of Adelie penguins in the Danger Islands, the researchers added. “Until recently, the Danger Islands wasn't known to be an important penguin habitat.” Heather Lynch, an ecologist from Stony Brook University who led the study, said, “These super habitats have gone undiscovered for decades partly because the islands themselves are distant and the dangerous waters that surround them.” The Danger Islands appears to have avoided recent loss in penguin population documented on other parts of the Antarctic Peninsula.

Another study published earlier suggested that more than 70 percent of king penguins may disappear by the end of the century as a result of global warming and overfishing. As the Danger Islands is likely to remain important islands for many penguins under climate change, scientists believe it deserves special consideration in the design of Marine Protected Areas in this area. “Now that we know how important this area is for penguin, we can better move forward designing Marine Protected Areas and managing the fishery,” said Lynch.

The idea of building the Marine Protected Areas, which covers 1.8 million square km of the Weddell Sea and around the Antarctic Peninsula, was first put forward by the European Union and supported by nongovernmental organization Greenpeace. In January, a global campaign has been started in the vast fishing-free zone to better protect wildlife.

C. Researcher may have never been to the Antarctic Peninsula.

D. The Danger Islands may be fit for penguins to live on.

2.What does the underlined word “census” in paragraph 2 mean?

A. Population count. B. Living condition.

C. Birth. D. Desert.

3.Why are there many penguins on the Danger Islands?

A. The Danger Islands is unknown for humans.

B. There is little climate change there.

C. Many people are protecting penguins.

D. The Danger Islands is free from being disturbed by humans.

4.What can we know from what Lynch said?
