Most schools forbid chewing gum, but in a few years they might consider changing that rule．Why? Scientists are finding evidence that gum chewing may be good for your health．It may even help improve your test scores．
This exciting research is just beginning．And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath．
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream．That's because the lining(膜)of our cheeks can absorb certain substances more quickly than our stomachs and intestines(肠)can．
That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and more．Scientists might even create antimicrobial(抗菌的)gums that cure bad breath．
Those projects may take years, but gum scientists have already had at least one recent success：They've created a gum that could help us stay awake．
Researchers have produced a gum called Stay Alert．Each stick has as much caffeine as a cup of coffee．It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes．
The gum is easy to transport and it's stable in cold and hot climates．Unlike a pill, it doesn't require water to swallow．Those qualities make it easy for soldiers to use．
For now, Stay Alert is available only to the military(军队)．The manufacturer may one day offer it for sale to the public．People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert．

Odland remembers like it was yesterday working in an expensive French restaurant in Denver．The ice cream he was serving fell onto the white dress of a rich and important woman．
Thirty years have passed, but Odland can't get the memory out of his mind, nor the woman's kind reaction．She was shocked, regained calmness and, in a kind voice, told the young Odland,“It's OK．It wasn't your fault．”When she left the restaurant, she also left the future Fortune 500 CEO with a life lesson：You can tell a lot about a person by the way he or she treats the waiter．
Odland isn't the only CEO to have made this discovery．Rather, it seems to be one of those few laws of the land that every CEO learns on the way up．It's hard to get a dozen CEO's to agree about anything, but most agree with the Waiter Rule．They say how others treat the CEO says nothing．But how others treat the waiter is like a window into the soul．
Watch out for anyone who pulls out the power card to say something like,“I could but this place and fire you,”or“I know the owner and I could have you fired．”Those who say such things have shown more about their character than about their wealth and power．
The CEO who came up with it, or at least first wrote it down, is Raytheon CEO Bill Swanson．He wrote a best-selling book called Swanson's Unwritten Rules of Management．
“A person who is nice to you but rude to the waiter, or to others, is not a nice person,”Swanson says．“I will never offer a job to the person who is sweet to the boss but turns rude to someone cleaning the tables．”

According to the text, most CEOs have the same opinion about ________．
Our boat floated on, between walls of forest too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains．Nowhere did we find a place where we could have landed：where the jungle did not actually spread right down into the river, banks of soft mud prevented us going ashore．In any case, what would we have sailed by landing?The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way．So we stayed in the boat, hoping we reached the sea, a friendly fisherman would pick us up and take us to civilization．
We lived on fish, caught with home-made net of string(we had no hooks), and fruits and nuts we could pick up out of the water．As we had no fire, we had to eat everything, including the fish, raw I had never tasted raw fish before, and I must say I did not much enjoy the experience; perhaps sea fish which do not live in the mud are less tasteless．After eating my raw fish, I lay back and dreamed of such things as fried chicken and rice, and ice-cream．In the never-ending damp heat of the jungle, ice-cream was a particularly frequent dream．
As for water, there was a choice：we could drink the muddy river water, or die of thirst．We drank the water．Men who had just escaped what had appeared to be certain death lose all worries about such small things as diseases caused by dirty water．In fact, none of us suffered from any illness as a result．
One day we passed another village, but fortunately nobody saw us．We did not wish to risk being taken prisoners a second time：we might not be so lucky to escape in a stolen boat again．
