Judging from recent surveys, most experts in sleep behaviour agree that there is an epidemic (流行病) of sleepiness in the nation. “I can’t think of a single study that hasn’t found Americans getting less sleep
than they ought to,” says Dr. David. Even people who think they are sleeping enough would probably be
better off with more rest.
The beginning of our sleep-lack crises can be traced back to the invention of the light bulb a century
ago. From diary entries and our personal accounts from the 18th and 19th centuries, sleep scientists have
reached the conclusion that the average person used to sleep about 9.5 hours a night. “The best sleep
habits once were forced on us, when we had nothing to do in the evening on the farm, and it was dark.” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock. “People cheat in their sleep, and they don’t even realize
they’re doing it,” says Dr. David. “They think they’re okay because they can manage with 6.5 hours, when they really need 7.5, 8 or even more to feel ideally energetic.”
Perhaps the most cruel robber of sleep, researches say, is the complexity of the day. Whenever
pressures from work, family, friends and community increase, many people consider sleep the least
expensive item on their programme. “In our society, you’re considered energetic if you say you need only 5.5 hours’ sleep. If you have to get 8.5 hours, people think you lack drive and ambition.”
To determine the consequences of sleep-lack, researchers have put subjects through a set of
psychological and performance tests requiring them, for instance, to add columns of numbers or recall a
passage read to them only minutes earlier. “We’ve found that if you’re lacking in sleep, performance
suffers,” says Dr. David. “Short-term memory is weakened, so are abilities to make decisions and to
concentrate.”

High school dropouts(辍学者)earn an average of $ 9 ,000 less per year than graduates. Now a
new study dispels a common belief why they quit. It’s much more basic than flunking out(不及格).
Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy ,and
perhaps not two bright.So researchers were surprised when they asked more than 450 kids who
quit school about why they left.
""The vast majority actually had passing grades and they were confident that they could have
graduated from high school. “ John Bridgeland , the executive researcher said. About 1 million teens
leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)
students will receive a diploma(证书) ,and actually all dropouts come to regret their decision.
So , if failing grades don’t explain why these kids quit , what does? Again ,John Bridgeland : “The
most dependable finding was that they were bored. “ They found classes uninteresting; they weren’t
inspired or motivated. They didn’t see any direct connection between what they were learning in the
classroom to their own lives , or to their career aspirations. "
The study found that most teens who do drop out wait until they turn sixteen , which happens to be
the age at which most states allow students to quit. In the US ,only one state ,New Mexico ,has a
law requiring teenagers to stay in high school until they graduate. Only four states: California ,
Tennessee , Texas and Utah , plus the District of Columbia , require school attendance until age 18 ,
no exceptions , another researcher ,says raising the compulsory attendance age may be one way to
keep more kids in school.
""As these dropouts look back ,they realize they’ve made a mistake. And anything that sort of
gives these people an extra push to stick it out and it through to the end , is probably helpful measure. ""
New Hampshire may be the next state to raise its school attendance age to 18. But critics say that
forcing the students unwilling to continue their studies to stay in school misses the point-the need for
reform. It"s been called for to reinvent high school education to make it more challenging and relevant ,
and to ensure that kids who do stick it out receive a diploma that actually means something.

Honesty comes in many forms. First there’s self-honesty. Is what people see the real article or do
you appear through smoke and mirrors? I find that if I try to be something I’m not, I feel unsure of
myself and take out a part from my PBA(personal bank account ). I love how singer Judy Garland put
it, “Always be a first-class version(版本) of yourself , instead of a second-class version of somebody
else .”
Then there’s honesty in our actions. Are you honest at school, with your parents, and with your
boss? If you’ve ever been dishonest, I think we all have, try being honest, and notice how whole it
makes you feel. Remember, you can’t do wrong and feel right. This story by Jeff is a good example
of that:
In my second year of study, there were three kids in my math class who didn’t do well. I was really
good at it. I would charge them three dollars for each test that I helped them pass. I’d write on a little
piece of paper all the right answers, and hand them off.
At first I felt like I was making money, kind of a nice job. I wasn’t thinking about how it could hurt
all of us. After a while I realized I shouldn’t do that anymore, because I wasn’t really helping them.
They weren’t learning anything, and it would only get harder down the road. Cheating certainly wasn’t
helping me.
It takes courage to be honest when people all around you are getting away with cheating on tests,
lying to their parents, and stealing at work. But, remember, every act of honesty is a deposit(储蓄)
into your PBA and will build strength .

B. Don’t copy others or you can’t be the first class.

D. Don’t learn from others unless they’re excellent.
3. What does the author expect to show by Jeff’s story?
A. honesty can be of great help.
B. A bad thing can be turned into a good one.
C. Helping others cheat can do good to nobody but yourself.
D. One should realize the wrong in his bad deeds.
4. In the last paragraph the author mainly wants to express _______ .

C. one should be honest when making a deposit
D. honesty in one’s actions can help him in the future
