When I was 13, my bedroom walls were covered with posters of the Monkees and Beatles. I wrote fan letters and daydreamed about meeting the objects of my affections. I begged my parents to attend every rock concert and watch every TV show featuring my favorite celebrities (名人) ; my friends and I discussed for hours all the things we would say and do when we met our favorite movie stars and pop singers. I drove my mother crazy! But after a few years, my obsession (迷恋) stars faded as I matured and gained the confidence to socialize with "real" boys.

In the 35 years since I was a teenager, celebrity worship (崇拜) has increased among teens due to the explosion of television celebrity gossip shows, and instant access to celebrity news on the Internet. It's no wonder that many teens are obsessed with stars when news programs often are filled with entertainment stories and the lives of celebrities.

Celebrity worship syndrome (综合征) is now considered a personality disorder. While it is normal for teenagers to follow the lives of their favorite stars, parents should try to monitor everything their child finds interesting. Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family. When teens talk a lot about celebrities and view them as just means of entertainment, this is considered normal celebrity worship. However, when a teenager is obsessed with a star and often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star, this may be the time for concern.

Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low self confidence and depression. Teens who are overly obsessed with stars often have damaged relationships with their parents.

A.teens today are not so obsessed with celebrities

New research shows that the healthy brain may hold memories which we don’t even remember. In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky.

Memory Check

First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance(核磁共振) imaging.

While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior（后部的） median temporal lobe(脑叶) -- when they saw words that had been on the first word list.

But participants didn’t always remember that they’d seen those words before. Sometimes, they goofed and said they hadn’t seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants’ consciousness, the researchers note.

“Album”of Memories

Another part of the median temporal lobe also attracted the scientists’ attention. The anterior（前面的）median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows.

So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling(决斗) for the upper hand in deciding what actually happened in the past, the study notes.

In other words, memories might have a photo album in the brain, but sometimes we forget what’s on all of the photo album’s pages.

A. he is unconscious when he gets his memories

2.According to the passage the researchers are .

A. studying how a person remembers things

B. studying a magazine The Journal of Neuroscience

C. examining posterior and anterior median temporal lobes

D. doing experiments to find out what disturbs a person’s memory

3.What did the experts discover when the participants saw the words on the first word list appear on the second word list?

A. The instrument worked faster.

B. The participants were more conscious.

C. The posterior median temporal lobe was more active.

D. The anterior median temporal lobe was more active.
