The way not to fall asleep at work is to take naps when you need them . “We have to totally change our attitude toward napping ,” says Dr. William Dement of Stanford University , the godfather of sleep research .
Last year a national commission led by Dement identified(发现) 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 half---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 .
小题1:The research done by the Dement Commission shows that Americans .
| A．don’t like to take naps |
| B．are terribly worried about their national debt |
| C．think that lack of enough sleep causes many accidents |
| D．have caused many industrial and traffic accidents |
- warnus of the wickedness of napping
C. discuss the side effects of napping
D. convince the reader of the necessity of napping
小题3:The “American sleep debt”(Line 1 , Para .3) is the result of .
- thetraditional misconception the Americans have about sleep
- thenew sleep policy of the Clinton Administration
- therapid development of American industry
- theAmericans’ worry about the danger of sleepiness
- preferableto have a sound sleep before a night shift
- goodpractice to eat something light before we go to bed
- essential(基本的) to makeup for lost sleep

Goat meat is high in protein(蛋白质)and lower in unhealthy fat than many other meats．Even so，the industry is small compared to chicken，beef and pork. But immigration has brought more of a taste for goat to America from all over the world.
Experts from the University of Illinois offer some questions for people to consider if they are thinking about raising goats．
First of all，do you understand that there always has to be someone to care for the goats?
◆How much land do you have available? And how good is it? Poor ground may support two to four goats on half a hectare．Better grassland can support six to eight. If goats and cattle share the land，two goats can be added for each cow. The goats will eat weeds and other plants that cattle do not like．
◆Do you have buildings for the number of female goats you plan to keep during winter? An open，cold，dry barn is better than a closed，warm barn where the air is wet．
◆Do you have the equipment to clean barns（畜棚） and to harvest hay（草料） to feed your goats? Or will you get someone else to do it，or buy the hay?
The experts say a profitable business in goat meat may take three to five years to establish．And, of course, there are no guarantees .
小题1:On which section of a newspaper will this passage appear?
| A．International Affairs | B．Entertainment |
| C．Agriculture | D．Culture |
| A．Goat meat is healthy food. |
| B．Immigrants bring different tastes. |
| C．The industry still leaves room for profit. |
| D．Raising goats is challenging. |
| A．32 cows and 64 goats． | B．32 cows and 32 goats． |
| C．16 cows and 32 goats． | D．8 cows and 16 goats． |
| A．You can make sure money． |
| B．You had better be cautious and patient． |
| C．Goats are hardly possible to raise． |
| D．Goat meat still needs to be recognized． |
Dr. Michael Osterholm is a former adviser to the U.S. Department of Health and Human Services. “I know less about influenza today than I did 10 years ago,” he says in a joking way. “Every stone we"ve turned over, we get more questions.”
The flu rectums every season and the world experiences terrible pandemics (全国或全世界范围流行的疾病), but researchers still do not understand why some strains infect people and others do not; they are not entirely sure about how the flu is transmitted; nor do they understand why some patients become seriously ill while others develop mild symptoms (症状). As a result, when a new strain shows up — like H1N1 — they often have little information to fall back on, and the lessons of previous pandemics are only somewhat helpful. While researchers are still putting together a complete picture of H1N1, for example, its most striking difference with the seasonal flu is that the elder1y are not the most vulnerable (易受攻击的) population.
Influenza"s unpredictable nature makes it a moving target for researchers, says researcher Allison Aiello at the University of Michigan. “Even if we had complete seasonal flu data from the past, it wouldn"t be much helpful for a new strain of influenza,” she explains.
Whi1e researchers are frustrated by the holes in their knowledge, they say, however, that the pub1ic--health community is generally doing a very good job responding to H1N1 with seasonal flu data that do exist. Studying influenza, says Osterholm, is “like looking through the windows of a house you can"t get into because the door is locked.” Gathering the data researchers do have is like “looking through the windows to get a pretty good picture of what the inside looks like.”
One thing researchers do know for sure: the best way for people to protect against H1N1 is to get the vaccine once it becomes available to them.
小题1:What do we learn about H1N1 from the passage?
| A．In fact it is not a kind of influenza virus. |
| B．It is quite possible to predict it in theory. |
| C．Old people are more likely to contract it than kids. |
| D．Receiving vaccines will be effective to protect against it. |
| A．rely on | B．pass on | C．col1ect | D．exchange |
| A．It is useless to study them. |
| B．It is still necessary to study them. |
| C．They are misleading most of the time. |
| D．They are much more helpful than expected. |
| A．Outbreaks of the flu | B．Symptoms of the flu |
| C．Mysteries of the flu | D．Risks of the flu |
About 45 percent of children suffer passive smoking in families, 50 percent in public places, and almost 6 percent on public transportation, shows a research released by the Shanghai Children"s Medical Center on Tuesday.
"Not only adults but also children and newborn babies are at risk for the adverse effects of p
assive smoking," said Tang Jingyan, a doctor at the Shanghai Children"s Medica
l Center."Actually, those young children whose bodies are still growing and developing are more sensitive to the effects of secondhand smoke."
Research has shown that children who are exposed to secondhand smoke will suffer from more colds, coughs and sore throats, and they are more likely to suffer from bronchitis, pneumonia and will have a higher risk of developing cancer.
Doctors even suggested that children suffering passive smoking are more likely to have behavioral problems and may not develop mentally as qui
ckly as their peers．Other research by the Shanghai Children"s Medical Center has found that more than 80 p
ercent of child patients in the center live in a smoke-filled household, where one or both parents smoke．"Th
ough doctors have stressed the harm of passive smoking over and over, it is still hard to reach a totally "smoke free" home," said a pediatrician named Zhang Yiwen, noting that parents are often tempted to smoke even though they have learned the harmful effects of secondhand smoke.China has 540 million people suffering from passive smoke, 180 million of them younger than 15．The age of smokers is also getting lower, earlier reports said.
"There are more young smokers than before．You can see young people wearing a school uniform and carrying a schoolbag light a cigarette on the street．Some of them are even female students," said Jing Xingming, a professor of children"s developmental behavior at the center.
"Children like to imitate adults, especially their parents．If parents often smoke at home, it is very likely children will develop
a smoking habit, which can cause a vicious circle," Jin said.Reports from the Ministry of Health said China has about 350 million smokers, of whom 15 million are underage smokers．Also, around 40 million of the country"s 130 million children aged between 13 and 18 had tried smoking, and 15 million had become addicted to tobacco.
小题1:What is the main idea of the passage?
| A．About half of the youngsters are suffering from secondhand smoke. |
| B．Experts are calling for more protection for youngsters from smoking. |
| C．More and more youngsters are picking up the habit of smoking. |
| D．Smoking does great harm to the health of the youngsters. |
| A．Children of non-smoking mothers. | B．Children of non-smoking fathers. |
| C．Children of heavy smokers. | D．Children from some smoking centers. |
| A．Cancer. | B．Behavioral problems. | C．Sore throats. | D．Coughs. |
| A．complete | B．simple | C．great | D．bad |
| A．About 80% of the children in the Shanghai Children"s Medical Center smoke heavily. |
B．About 45 percent of children suffer passive smoking in  the Shanghai Children"s Medical Center. |
| C．About 540 million people are heavy smokers in China. |
| D．Children aged between 13 to 18 are more likely addicted to smoking. |
Recently the World Health Organization announced that the disease of smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox be
gan to disappear.71．Vaccination against smallpox has been so successful that _________ .
A．the discoverer made a large amount of money
B．Dr Jenner was given a prize by the World Health Organization
C．smallpox has almost disappeared in most countries
D．smallpox was no longer in existence on earth
72 ．Smallpox has been prevented from spreading through the following measures EXCEPT that _____.
A．most people were vaccinated against the disease at least once
B．people going abroad should promise not to spread the disease
C．people travelling from one country to another must prove they
are vaccinated
D．people must be vaccinated shortly before going to foreign countries
73 ．What led Dr Jenner to experiment with vaccination was that ________ .
A．he wanted to make a great discovery and publish it
B．vaccination could make people"s arms safe
C．he tried to cure the farmers of some disease caught from the cattle
D．those who worked with cattle seemed free from getting smallpox
74．The doctor"s new discovery was called ‘vaccination’ for the reason that ________ .
A．he discovered smallpox near a farm
B．he experimented with a disease from the cattle
C．he was working with cattle in the countryside
D．people got the disease of smallpox from the cattle
75．The news of the discovery ________.
A．caught people"s attention from all corners of the world
B．spread far and near in the western countries
C．made people rush to Dr Jenner for vaccination
D．helped to get rid of the terrible disease of smallpox
