A new study found that nearly half of bald eagles    1    (test) across the United States show signs of repeated lead (铅) exposure. Researchers examined the blood, bones, feathers and liver tissue (肝脏组织) of l,210 eagles between 2010 and 20l8.

Lead is a poisonous substance     2     affects the nervous system and interferes (妨碍) with the normal function of nerve cells. Even in low amounts, lead can reduce bald eagles’ ability     3     (fly), hunt and reproduce. In high amounts, lead causes     4    (breathe) difficulty and death.

Bald eagles are one of America’s most celebrated conservation success stories. The birds       5    (remove) from the U. S. Endangered Species List in 2007. But scientists say that high lead levels are still     6     concern. Lead exposure also reduces their ability to face future difficulties, such as climate change or infectious diseases.

“Lead is available to these birds more than we     7    ( previous) thought,” said VinceSlabe, a research wildlife biologist at the nonprofit group Conservation Science Global.

The blood samples from live eagles in the new study were taken from birds trapped andstudied     8    other reasons. The bone, feather and liver samples came from eagles killed by vehicles, power lines or other causes.

The researchers also found higher levels of lead exposure in fall     9    winter. During these months, eagles eat animal remains left by hunters. These remains often contain many    10    (piece) of lead ammunition (弹药).

“An earlier study showed chimpanzees would fold up the table of other chimpanzees     9     (steal) food from them. But they would not punish chimpanzees who just happened     10     (have) more food,” Santos said. “In other words, it was fine if chimpanzees had more food as long as they did not steal it.”

Scientists exploring the ocean floor in Antarctica(南极洲) have found a larger group of fish nests(鱼巢)    1     ever before. The discovery came as a surprise, and it will help scientists develop a more complete idea of the ocean food web in the area.

In the south Weddell Sea, not far from Antarctica’s Filchner Ice Shelf, scientists were    2    (amaze) to discover a group of about 60 million icefish nests on the ocean floor. Before this, the    3    (large) group of icefish nests that had ever been found includes less than 60 nests. Lilian Boehringer, a research student, was the first    4    (discover) the nests. “They were everywhere,” she told The New York Times.

The researchers used a special device called OFOBS to make two more four-hour “lives”,    5     (try) to discover the limits of the nesting area. The nests scientists found were in the shape of    6    circle. Each nest held about 1,700 eggs. Usually, Weddell seals(海豹)    7     (spot) in the waters above the nesting site. Trackers    8    (fix) on some Weddell seals show that they dive all the way to the sea floor.

The team placed a camera on the sea floor before leaving,     9     will take a picture of the nests in the area    10    (two) a day for the next two years. They hope the pictures from this camera will help them learn more about the lives of the icefish.
