In the past, man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be 46 . Today things are 47 , the world has
become too 48 . We are using up our natural resources too quickly, and at the same time we are 49 our environment with dangerous chemicals. If we continue to do this, human life on the earth 50 survive.Everyone 51 today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing 52 , more and more fish are caught. We know that if too many trees are cut down, 53 will disappear and nothing will grow on the land. Yet, we 54 to use bigger and more powerful machines to 55 more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. 56 , in most countries wastes are 57 put into rivers or into the sea, and there are 58 laws to stop this. We know, too, that if the 59 of the world continues to rise at the present rate, in a few years there will not be enough 60 . What can we do to solve these problems ?
If we eat more vegetables and less 61 , there will be more food available for everyone. Land that is used to grow crops 62 five times more people than land where animals are kept. Our natural resources will 63 longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth 64 .
Finally, if we educate people to think about the problems, we shall have a better and clearer 65 in the future.

I know lots of women who skip breakfast , and they have a ton of different excuses for doing it . Some say they don’t have time. others think they’re “saving” calories, still others just don’t like breakfast food .
But the bottom li
ne is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece. Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at
the University of Southem California found that breakfast s
kippers have a bigger chance of gaining weight than those who regularly have a morning meal. So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
小题1:The word “leftovers” in Paragraph 1 probably means__________.
| A．things left undone | B．food remaining after a meal |
| C．meals made of vegetables | D．pizza topped with fruit |
| A．Working women usually have breakfast in a hurry. |
| B．There are some easy ways of cooking a meal. |
| C．Many people have wrong ideas about breakfast. |
| D．Eating vegetables helps save energy. |
| A．eat something for breakfast | B．put away the leftovers instead of eating more. |
| C．heat up leftovers for breakfast | D．eat calorie-controlled food |
| A．who go to work early | B．who stay up late |
| C．who want to lose weight | D．who eat before sleep |
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
- naturalto take a nap whenever we feel the need for it
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. |
