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.
_______(50)
A.Prisoners of war and others in dire situations,for instance,often turn to dark humor.
B.It turns out that humor influences health and social well-being in many ways.
C.The funniest jokes carry a little edginess（急躁）,but not too much.
D.But can the same be said for humor as a whole?
E.Maybe practice does make perfect.
F.Laughter is the bridge between dreams and reason,and ev6ry good bridge needs abutments.

When We Are Asleep
Everyone dreams,but some people never recall their dreams,or do so very rarely.
Other people always wake up with vivid recollections（记忆）of their dreams, though they
forget them very quickly.In an average night of eight hours' sleep,an average adult will
dream for around one hundred minutes,probably having three to five dreams,each lasting
from ten to thirty minutes.
Scientists can detect when someone is having a dream by using an instrument which
measures the electrical waves in the brain.During dreaming,these waves move more
quickly.Breathing and pulse rate also increase,and there are rapid eye movements under
the lids，just as though the dreamer were really looking at moving objects.These signs of
dreaming have been detected in all mammals（哺乳动物）studied, including dogs,
monkeys, cats, and elephants, and also some birds and reptiles（爬行动物）.This period
of sleep is called the"D"state.Babies experience the"D"state for around 50%of their
sleep;the period reduces to around 25%by the age of 10.
Dreams take the form of stories,but they may be strange and with incidents not
connected,which make little sense.Dreams are seldom without people in them and they
are usually about people we know.One estimate says that two-thirds of the"cast"of our
dream dramas are friends and relations.Vision seems an essential part of dreams,except
for people blind from birth.Sound and touch are senses also often aroused,but smell and
taste are not frequently involved.In"normal"dreams,the dreamer may be taking part,or
be only an observer. But he or she cannot control what happens in the dream.
However,the dreamer does have control over one type of dream.This type of dream is
called a "lucid"（清醒的）dream. Not everyone is a lucid dreamer. Some people are
occasional lucid dreamers.Others can dream lucidly more or less all the time.In a lucid
dream,the dreamer knows that he is dreaming.
In a lucid dream we can use Morse code to communicate with others.

Will We Take Vacation in Spaces?
When Mike Kelly first set out to build his own private space-ferry service,he figured his bread-and-butter business would be lofting satellites into high-Earth orbit. Now he thinks he may have figured wrong.“People were always asking me when they could go,”says Kelly,who runs
Kelly Space TechnologT out of San Bernardino,Californi a.“I realized that real market is in space tourism.”
According to preliminary market surveys,there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington,Virginia,has taken more than 1 30 deposits for a two-hour,$98,000 space tour tentatively(and somewhat dubiously)set to occur by 2005 .Gene Meyers of the Space Island Group says:“Space is the next exotic vacation spot.”
This may all sound great,but there are a few hurdles.Putting a simple satellite into orbit with no oxygen,life support or return trip necessary already costs an astronomical $22,000/kg.
And that doesn't include the cost of insuring rich and possibly litigious passenger. John Pike of the
Federation of American Scientists acerbically suggests that the entire group of entrepreneurs trying to corner the space tourism market have between them“just enough money to blow up one rocket.”The U .S.space agency has plenty of money but zero interest in making space less expensive for the little guys.So the little guys are racing to do what the government has failed to do:design a reusable launch system that's inexpensive,safe and reliable.Kelly Space's prototype looks like a plane that has sprouted rocket engines.Rotary Rocket in Redwood City,California,hasa booster with rotors make a helicopter-style return to Earth;Kistler Aerospace in Kirkland,Wash- ington,is piecing together its versions from old Soviet engines,shuttle-style thermal protection tiles and an elaborate parachute system.The first passenger countdowns are still years away,but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations.After all,you can't be too prepared for a trip to that galaxy far,far away.
For those who are intent on joining the 100-mile high club,Hilton and Budget are plotting to build space hotels.Before the Russian space Mir came down,some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space,and if you're thinking of staying in it,you may want to check the Michelin ratings before booking yourself a suite.
Space Adventure in Arlington has taken 130 deposits totaling $ 98,000 for a two-hour space tour.
