Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.1.

One idea is that sleep helps us strengthen new memories. 2. We　 know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.3.

Now we have the most direct evidence yet that he is right.4. The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size.　 5. “You keep what matters,” Tononi says.

A. We should also try to sleep well the night before.

B. It’s as if the brain is preserving its most important memories.

C. That’s why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.

G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.

More Americans are turning to charm school to gain an advantage over competitors in a job market stricken by the longest economic slowdown since the Great Depression.

Etiquette (礼节) trainers report business growing from clients who believe that good manners could be the key selling point that helps them get hired or keeps them off the unemployment line.

“People are prepared to do whatever it takes to keep their job”, said Gloria Starr, an adviser on image, etiquette and communications in North Carolina. Starr, who says business is up 40 percent in the past year at her school, said people were “realizing that it takes more than just ability and knowledge” to keep or win a job.

Peggy Newfield, who has been teaching etiquette for 30 years and runs a charm school, said business was “booming.” “When the economy is down etiquette training will always be up. They’re focusing on ‘What I can do to survive, I really have to keep up my game because the competition is keen.’”

Proper business manners, however, extend far beyond greeting or thanking a would-be employer. Etiquette classes deal with the basics of presentation in an interview, including what to say and how to dress.

“It’s so much more than writing the thank-you note at the end,” Newfield said. “It’s about walking in for the job interview, every hair is in place, your clothes are perfectly pressed, your shoes are polished, you’re groomed to the nines, you speak the part, and your English is correct.”

It’s great that we have seen this renewal in etiquette and manners and self respect.

Studies have shown that 85 percent of the reason a person gets a job, keeps a job and moves up is related to their personal skills. There are very few jobs out there where your manners, where your socials skills, are not a big piece of being successful. If you have manners you can walk into any business or social situation.

Teaching etiquette has become a tougher task. Some people point to bad public behavior by athletes and celebrities (名人) as a factor in ruining good manners in U.S. society. Hotel owner Paris Hilton, actress Lindsay Lohan and singer Britney Spears are among those who have been charged with setting a poor example, especially for children and adolescents. Hilton is infamous （声名狼藉的）for a sex tape that became an Internet hit, Lohan has long been gossip stuff due to her quarrels with the law and Spears was photographed partying without underwear.
