happen?Research is28,but some studies suggest that people who can master luciddreaming-that is,the ability to be 29 that a nightmare is happening and possibly evencontrol it without waking up-may hold the 30.Nightmares are part of the human experience,especially for kids.Doctors31 don'tconsider occasional nightmares a problem.They can just be symptoms of a sleep disorderthat can 32 from an unpleasant experience,stress,or certain drugs.To treat the disorder,there are a number of medicines and therapies that arebacked by_33research,according to the American Academy of Sleep Medicine,which analyzed the available research on the treatment of nightmare disorder in a recent34 published in the Journal of Clinical Sleep Medicine.However,nightmares are complicated,and researchers are still

spend much more time with digital media than we did a decade ago.Buttoday's teens have grown up with smartphones.Compared with teens a couple ofdecades ago,the way they interact with traditional media like books and movies isfundamentally different.B)Analysis of surveys of over one million teens in the United States collected since 1976reveals a major shift in how teens are spending their leisure time.Paper books are beingignored,in favor of screens.Digital devices are changing other behaviors,too.Moreand more,young people choose spending time on their electronic devices over engagingin other activities,regardless of the type.Indeed,by 2016,the average American highschool senior said they spent six hours a day writing text messages,on social media,and online during their free time.And that covers just three activities,and if otherdigital media activities were included,that estimate would no doubt rise.C)Teens did not always spend that much time with digital media.Online time has doubledsince 2006,and social media use has moved from a periodic activity to a daily one in thesame period.By 2016,nearly nine out of ten young women in the 12th grade said theyvisited social media sites every day.Meanwhile,time spent playing video games rosefrom under an hour a day to an hour and a half on average.One out of ten American 8thgrade students in 2016 spent 40 hours a week or more playing video games.Let meemphasize that this is equal to the time most adults spend per week at work.2021年12月英语四级真题第3套第2页共8页D)If teens are spending so much time using electronic devices,does that mean they haveto give up some other activities?Maybe not.Over the years,many scholars haveinsisted that time online does not necessarily take away time spent engaging withtraditional media or on other activities.Some people,they argue,are just moreinterested in certain kinds of media and entertainment.Thus,using more of one type ofmedia does not necessarily mean less of the other.E)That may be true,but that still does not tell us much about what happens across a wholegeneration of people when time spent on digital media grows.Large surveys conductedover the course of many years tell us that American youth are not going to the cinemanearly as often as they did in the past.While 70 percent of 8th and 10th grade studentsused to go to the movies once a month or more,now only about half do this.More andmore,watching a movie is something teens choose to do on their electronic devices.Why is this a problem?One reason is that going to the cinema is generally a socialactivity.Now,watching movies is something that most teens do alone.This fits a largerpattern.In another analysis,researchers found that today's teens go out with theirfriends much less often than previous generations did.F)But the trends related to movies are less disturbing compared with the change in howteens spend their time.Research has revealed an enormous decline in reading.In 1980,about 60 percent of senior high school students said they read a book,newspaper ormagazine every day that was not assigned for school.By 2016,only 16 percent did.This is a huge drop and it is important to note that this was not merely a decline inreading paper books,newspapers or magazines.The survey allowed for readingmaterials on a digital device.G)Indeed,the number of senior high school students who said they had not read anybooks for pleasure in the last year was one out of three by 2016.That is triple thenumber from two decades ago.For today's youth,books,newspapers and magazineshave less and less of a presence in their daily lives.Of course,teens are still reading.But they are generally reading short texts.Most of them are not reading long articles orbooks that explore deep themes and require critical thinking and reflection.Perhaps notaccidentally,in 2016 reading scores were the lowest they have ever been since 1972H)This might present problems for young people later on.When high school students goon to college,their past and current reading habits will influence their academicperformance.Imagine going from reading texts as short as one or two sentences totrying to read entire books written in complex language and containing sophisticatedideas.Reading and comprehending longer books and chapters takes practice,andAmerican teens are no longer getting that practice.I)So how can this problem be solved?Should parents and teachers take away teens2021年12月英语四级真题第3套第3页共8页
