Ha!The Sdence of When We Laugh and Why
It's certainly possible to over-analyze a joke._______(46)Considering the abundant research on the topic,maybe not.
Scott Weems,a neuroscientist,takes readers on a wide-ranging tour that explains what humor is and why readers should care.______(47)Humor improves interpersonal relationships,and studies show that simply watching a funny movie can lower stress,improve immune system response and even help viewers better solve problems.
The complexity of the human brain makes humor possible,Weems argues,and it also helps explain how some people can find a joke hilarious while others deem it grossly offensive.
Humor takes many forms-as many as 44 by one researcher's count-but shares certain traits and themes.From puns and riddles to slapstick(打闹剧),humor is inherently subversive , Weems says , often treating serious subjects with frivolity(轻浮)or even rudeness.______(48) Ha ! Isn ' t a self-help guide to being funny , though a careful reader can find useful nuggets(块金) throughout?______( 49 ) Surprise helps , too , whether it ' s the incongruity(不协调)of an elephant hiding in a cherry tree or the absolute improbability of Raquel Welch and the pope ending up in the same lifeboat.
The final chapter divulges(透露)Weems's semi-successful attempt at stand-up comedy.He got a few laughs,he says,but not where he expected them. ______(50)The joke that got Weems the most laughs,and judged by one website's readers as the best in the world,is a story that he had practiced many dozens,maybe hundreds,of times.

More Than 8 Hours Sleep Too Much of a Good Thing
1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling re-freshed after a night's sleep than 8-hour sleepers.
3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night.He added that“it might be a good idea” for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cau-tioned that more research is needed to confirm this.
4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep ques-tionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
6 Kripke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.
