Because these whistles are actually names of dolphins—and every dolphin has one.Scientists call these sounds a “signature whistle”．When other dolphins hear the whistle，they know which dolphin is calling.‎ Dolphins often hunt by themselves but still need to stay connected to the group.Since they can't always see each other，dolphins use their signature whistles to check in with other dolphins hundreds of yards away.“In coastal areas，dolphins exchange whistles even when they're a third of a mile apart，”says Greg Campbell，who studies animals.That means dolphins shout out to group members that might be nearly five football fields away.‎ What's amazing is who names the baby dolphin.Not the mother.Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle.Like human babies，a baby dolphin plays with sounds throughout 7‎ ‎ its first year.While testing its sound skills，a baby dolphin is doing something amazing.It's creating or figuring out its signature whistle.How or why it chooses its signature whistle is not clear.Studies show that most of the time the signature whistle is nothing like its mother's or group members' whistles.‎ When the baby dolphin is about a year old，its signature whistle is set.It repeats it often so the other dolphins learn to recognize it.‎ Deciphering (破译) dolphins' names is just the beginning of figuring out what dolphins communicate about.Do they chat about sharks? Discuss the tides? Maybe they even have a name for people.Someday scientists will decipher the rest of dolphins' communication.‎ ‎【解题导语】　本文是一篇说明文。主要讲科学家破译了海豚发出的一种哨音，这种哨音其实就是海豚的名字。‎ ‎5．The sound is important for dolphins because of ________.‎ A．their poor sense of direction B．their living environment C．their strong enemies D．their big groups 解析：选B　细节理解题。根据第一段中的“Dolphins (海豚) live in a dark...important role in their survival.”可知，海豚生活在黑暗的海底世界，什么也看不到，因此，声音对它们的生存起着重要的作用。‎ ‎6．The dolphin's signature whistle ________.‎ A．lasts a long time B．can travel long distances C．is especially helpful in hunting D．can be recognized by other animals 解析：选B　细节理解题。根据第三段中的“dolphins exchange whistles even when they're a third of a mile apart”和“shout out to group members that might be nearly five football fields away”可知，这种哨音可以传播很远。‎ ‎7．The author writes the text mainly to ________.‎ A．encourage readers to study dolphins B．tell readers how dolphins communicate C．show how lovely and clever dolphins are D．introduce a special sound made by dolphins 解析：选D　写作目的题。根据第二段中的“Scientists haven't uncovered their 7‎ ‎ secret communication，except for one kind of whistle.”和最后一段可知，本文是在向读者介绍海豚发出的一种特殊的声音。‎ ‎8．A baby dolphin gets its name ________.‎ A．soon after it was born B．according to its size C．all by itself D．with the help of its group 解析：选C　推理判断题。根据第四段的叙述可知，幼小的海豚的名字是根据它自己发出的哨音确定的。‎ Ⅲ.语法填空 ‎(2019·全国卷Ⅱ)‎ A 90yearold has been awarded “Woman Of The Year” for 1.________ (be) Britain's oldest fulltime employee—still working 40 hours a week.Now Irene Astbury works from 9 a.m. to 5 p．m. daily at the pet shop in Macclesfield, 2.________she opened with her late husband Les.Her years of hard work have 3.________ (final) been acknowledged after a customer nominated (提名) her to be Cheshire's Woman Of The Year.‎ Picking up her “Lifetime Achievement”award，proud Irene 4.________ (declare) she had no plans 5.________ (retire) from her 36yearold business.Irene said，“I don't see any reason to give up work.I love coming here and seeing my family and all the friends I 6.________ (make) over the years.I work not because I have to,7.________ because I want to.”‎ Granddaughter Gayle Parks,31—who works alongside her in the family business—said it remained unknown as to who nominated Irene for the award.
