DAlmost all new parents struggle to get enough sleep while caring for their newborns.For somepenguin parents,though,periods of sleep are especially short.Researchers recently found that Chinstrap penguins only sleep for about four seconds at a timein order to protect their eggs and newborn chicks.They do this thousands of times throughout theday.The short "microsleeps"total around 11 hours each day.The microsleeps appear to be enoughto keep the parents going for many weeks.Niels Rattenborg is a sleep researcher at the Max Planck Institute for Biological Intelligence inGermany.He helped write the new study.He said,"These penguins blink their eyes open andshut,and they do it 24/7 for several weeks at a time.What's surprising is that they're able tofunction okay and successfully raise their young."Chinstrap penguins usually lay their eggs in November in nests made of small rocks.As withmany other kinds of penguins,mated pairs of Chinstrap penguins share parenting responsibilities.One parent usually watches the eggs and chicks alone while the other goes off fishing for familymeals.Adult penguins do not face many natural enemies in the mating season.But large birds calledbrown skuas eat penguin eggs and small chicks.Other adult penguins may also try to steal the smallrocks from nests.So,penguin parents must always be on guard.For the first time,scientists followed the sleeping behavior of Chinstrap penguins in anAntarctic mating colony.They did this by attaching devices that measure brain waves.Theycollected data on 14 adults over 11 days on King George Island off the coast of Antarctica."For these penguins,microsleeps have some restorative functions,"Rattenborg said.He addedthat they would not survive without it.The researchers did not collect sleep data outside the matingseason.But they suspect that the penguins may sleep for longer periods at other times of the year.32.What can we learn about Chinstrap penguins'microsleeps?A.They are a way to keep the sleeper safe.B.They only happen to newborn chicks.C.They happen to the sleeper once a day.D.They last only seconds.33.What about Chinstrap penguins makes Rattenborg surprised?A.Their sleep habit works well.B.They blink their eyes very frequently.C.They can stay awake for even weeks.D.They keep their eyes open while sleeping34.How did the researchers get their findings?A.They read and concluded.B.They filmed and recorded.C.They tested and compared.D.They followed and collected.35.What's the limit of the study?A.The equipment used was not advancedB.The researchers didn't follow the penguins all the year round.C.The study didn't include other species of penguins.D.The number of the penguins studied was not big enough.
