at the University of Pennsylvania School of Medicine,"There"s even a prohibition against admitting
we need sleep". Nobody wants to be caught napping or found asleep at work. To quote a
proverb:"Some sleep five hours, nature requires seven, laziness nine and wickedness eleven."
Wrong. The way not to fall asleep at work is to take naps when you need them."We have to
totally changeour attitude toward napping,"says Dr. William Dement of Stanford University, the
godfather of sleep research.
Last year a national commission led by Dement identified an"American sleep debt" which one
member said was as important as the national debt. The commission was concerned about the
dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may
be why we have a new sleep policy in the White House. According to recent reports, President
Clinton is trying to take a ha1f-hour snooze (瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have"a
mid afternoon quiet phase," also called "a secondary sleep gate." Sleeping 15 minutes to two
hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born
to nap.
We Superstars of Snooze don"t nap to replace lost shut-eye or to prepare for a night shift.
Rather, we "snack" on sleep, whenever, wherever and at whatever time we feel like it. I myself
have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices
and museums.

Maryland, decided to find out whether, as many smokers say, smoking helps them to"think
and concentrate." Spilich put young non-smokers, active smokers and smokers deprived
(被剥夺) of cigarettes through a series of tests.
In the first test, each subject (试验对象) sat before a computer screen and pressed a key
as soon as he or she recognized a target letter among a grouping of 96. In this simple test,
smokers, deprived smokers and non-smokers performed equally well.
The next test was more complex, requiring all to scan sequences of 20 identical letters
and respond the instant one of the letters transformed into a different one. Non-smokers
were faster, but under the stimulation of nicotine, active smokers were faster than deprived
smokers.
In the third test of short-term memory, non-smokers made the fewest errors, but deprived
smokers committed fewer errors than active smokers.
The fourth test required people to read a passage, then answer questions about it.
Non-smokers remembered l9 percent more of the most important information than active
smokers, and deprived smokers bested those who had smoked a cigarette just before
testing- Active smokers tended not only to have poorer memories but also had trouble
separating important information from insignificant details.
"As our tests became more complex." sums up Spilich," non-smokers performed better
than smokers by wider and wider margins". He predicts, "smokers might perform adequately
at many jobs- until they got complicated. A smoking airline pilot could fly adequately if no
problems arose, but if something went wrong, smoking might damage his mental capacity."
B. to show how smoking damages people"s mental capacity
C. to prove that smoking affects people"s regular performance
D. to find out whether smoking helps people"s short-term memory
B. put the subjects through increasingly complex tests
C. check the effectiveness of nicotine on smokers
D. register the prompt responses of the subjects
B. envied
C. caught up with
D. made the best of
B. Active smokers responded more quickly than the other subjects.
C. Non-smokers were not better than other subjects in performing simple tasks.
D. Deprived smokers gave the slowest responses to the various tasks.
B. smoking in emergency cases causes mental illness
C. no airline pilots smoke during flights
D. smokers may prove unequal to handing emergency cases
live fuller, happier lives.
Though we"re all born with SQ, most of us don"t even realize that we have it. Fortunately,
you don"t have to sign up for classes to learn how to improve your SQ. Here are some simple
steps that can lead you to this new level of understanding.
Sit Quietly. The process of developing spiritual intelligence begins with solitude(独处)and
silence. To tune in to your spirit, you have to turn down the volume(强度)in your busy, noisy,
complicated life and force yourself to do nothing at all. Start small by creating islands for
silence in your day. In the car, instead of listening to the music, use the time to think. At work,
shut the door to your office between meetings, take a few breaths and let them out very, very
slowly. Enjoy the stillness in your home after the kids are finally in bed.
Step Outside. For many people, nature sets their spirit free. Go outside to watch a beautiful
sunset. If you are walking with the dog, take the time to admire flowers in bloom; follow the
flight of a bird and watch clouds float overhead.
Ask Questions of Yourself. Ask open-ended questions, such as "What am I Feeling? What
are my choices? Where am I heading?"
But don"t expect an answer to arrive through some supernatural forms of e-mail. "Rarely do
I get an immediate answer to my question," says Reverend Joan Carter, a Presbyterian minister
in Sausalito, California. "But later that day I suddenly find myself thinking about a problem in a
perspective(角度) I never considered before."
Trust Your Spirit. While most of us rely on gut(本能的)feeling to realize danger, spiritual
intelligence pushes us, not away from, but towards some action that will lead to a greater good.
B. what your SQ is and in what way it can be improved
C. the relationship between your SQ and your life
D. advantages and disadvantages of SQ
means to_________
B. keep up your spirit
C. keep seated quietly
D. change your spirit
B. deep thought
C. spare time and hobbies
D. good spirits
B. You have to go to classes to learn how to improve your SQ.
C. SQ leads us to take wrong actions.
D. SQ can benefit our life.

called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common
symptoms.
Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other
microorganisms can poison eggs ,meat, vegetables, and many other foods. After entering the body, these
tiny living things release(释放) poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown,
processed or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects.
Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply
rapidly in dirty places and in warm temperatures. This means that people should never touch food with
dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People
should also wash food covered with chemicals before eating it. Finally, people should not eat wild
mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that
are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If
people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
B. Food poisoning means death.
C. Food poisoning comes in varieties.
D. Food poisoning can be serious.

C. can be noticed within hours
D. can be ignored

C. some tiny living things
