27.What do the researchers suggest in the last paragraph?A.Informing students the risk of energy drinks.B.Making parents aware of energy drinks.C.Increasing the price of energy drinks.D.Introducing the benefits of energy drinks.CBottlenose dolphin(宽吻海豚)moms make their different whistles(口哨)morehigh-pitched(声调高的)when their babies are near.When speaking to young kids,people often use sharp,high-pitched baby talk.Researches show that some dolphins do it like this,too.When their babies arenearby,bottlenose dolphin moms blow their whistles differently.This language fromparents could serve a similar role as it seems to in humans.It might increase thebabies'attention,researchers suggest.This might aid bonding and vocal learning.During the first few months of life,each common bottlenose dolphin develops aunique tune.This whistle is unique like a name.The dolphins shout out their own"names"in the water.The calls likely serve as a way to keep track of each other,says marine biologist Laela Sayigh.She works at the Woods Hole OceanographicInstitution in Massachusetts.But dolphin moms seem to tweak their pitch when they're with their babies.Young dolphins tend to stay by mom's side for three to six years.Researchers analyzed unique whistles from 19 female dolphins-both with andwithout their babies close by.This wild population lives near Sarasota Bay,Fla.Scientists have been studying this community of dolphins for decades.The audio wasrecorded during catch-and-release health checks done from 1984 to 2018.The researchers examined 40 instances of each dolphin's unique whistle.Half ofeach mother's whistles were voiced when her baby stayed with her.Whistles whenyoungsters were around had a wider range of pitches.On average,the highest pitchwas a bit higher than when babies weren't near.The lowest pitch was slightly lower.·1625DY·英语（二）-R-必修第一册-G DONG
