The world hash’t seen a pandemic（流行疾病）in 4 1 years，when the”Hong Kong”flu crossed the globe and killed about one million people worldwide．If H1N1 flu（甲型流感）reaches pandemic levels，what would happen next?
The outbreak of SA

RS in 2003 rang alarm bells as potential pandemics．Although it jumped the”animal-to·human”barrier，neither disease changed enough to enable human-to．Human infection．Strictly speaking，SARS did not become pandemics because it was too good at killing their hosts．For a pandemic，it needs to be able to maintain human-to．human contact without killing its host off．
”H1N1 flu is already a man-to-man disease，which makes it much more difficult to manage．
And H1N1 flu appears much more infectious than SARS．
But the WHO warns，it cannot say whether or not it will indeed cause a pandemic．According to experts，here’s what the world might see if there is another pandemic，based on past exp

erience．
The disease would skip from city to city over an 18-to-24 month period，infecting more than a third of the population．World health Organization officials believe as many as 1．5 billion people around the globe would seek medical care and nearly 30 million would seek hospitalization．Based on the last pandemic and current world population，as many as 7 million people could die．Hos

pitals will become overcrowded；scho

ols will close；businesses will close；airports will be empty．Business will become very bad，as people avoid as much social contact as possible．
Health facilities will become overrun with patients and there would be less-than-adequate staffing，as medical health professionals fall ill themselves and that would result in higher deaths．
The very young and very old will likely be the most susceptible（易受感染的）to the illness．Experts warn，much is still unknown about the current H1N1 flu virus and its severity and it is too early to say whether it will lead to a pandemic．Right now，the focus is on finding answers and controlling the spread．
小题1:How many kinds of disease is mentioned in the passage?

A．Two

B．Three

C．Four

D．Five

小题2:Which of the following statements is NOT true according to the passage?

A．SARS didn’t change enough to enable sustained（持续的）human-to—human infection．

B．SARS was very good at killing its carriers．

C．A man with H1N1 flu can not infect another man easily．

D．Comparing SARS and H 1N 1 flu，SARS is not as infectious．

小题3:What can we know about the “Hong Kong” flu from the passage?

A．It spread all around the globe and killed lots of people．

B．It killed about millions of people．

C．It killed about one million people in Hong Kong．

D．Not the old but the young were susceptible to it and got killed．

小题4:What can be inferred from the passage?

Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment.
Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school in New Jersey had to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area.
Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health.
Some governments have realized how serious the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods.
57．What is mainly discussed in the text?
A The effect of every chemical.
B．Problems of harmful waste.
C．Chemicals used for industrial processes.
D．Events related to waste chemicals.
58．From the text we know that ______.
A．chromium can poison people when there is a wind
B．chromium pollution makes the local government close the school
C．Some governments don’t realize how serious the problems are until people suffer a lot from harmful waste
D．about two-thirds of the waste can pollute the environment
59．Which of the following least matches the solution the writer refers to?
A．Chemicals used for industrial processes should be banned.
B．People can make use of the existing technologies and methods to reduce the waste
C．Policymakers make laws to limit the production of harmful waste.
D．People choose not to buy products which may produce harmful waste.
60．The writer of the text thinks that ______.
A．governments should have forbidden the production of waste chemicals
B．mixed waste chemicals can always be stored without endangering people
C．industries must not produce waste chemicals which harm people so much
D．everyone can do something to help solve the problem of waste chemicals

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don"t eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don"t overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don"t get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

The sleep debt is the difference between the amount of sleep you should get and the amount you actually get. It grows every time we skim some extra minutes off our nightly sleep. “People accumulate sleep debts gradually,” says Dr. William Dement, founder of the Stanford University Sleep Clinic. Studies show that such short-term lack of sleep leads to a foggy brain, impaired vision, worsened driving and troubled remembering. Long- term effects include obesity, insulin(胰岛素) resistance, and heart disease.
A 2007 survey by the National Sleep Foundation reports that Americans sleep for 6.9 hours per night, 6.8 hours on average during the week and 7.4 hours on the weekends. Generally, experts recommend eight hours of sleep per night, although some people may require only six hours of sleep while others need ten. That means on average, Americans lose one hour of sleep each night more than two full weeks of sleep every year.
The good news is that the sleep debt can be repaid with some work, though it won’t happen when you sleep longer for once. Adding an extra hour or two hours of sleep a night is the way to catch up. For the long-term sleep shortage, it takes a few months to get back to natural sleeping pattern, says Lawrence J. Epstein, medical director of the Harvard Sleep Health Center.
Go to bed when you are tired, allowing your body to wake you in the morning, with no alarm clock. You may find yourself uncomfortable at the beginning of the recovery cycle. Expect to bank to ten hours shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease. For recovery sleep, both the hours of the sleep and the intensity(强度) of the sleep are important. The most refreshing sleep occurs during deep sleep, which is generally considered a restorative (促使健康的) period for the brain. And when you sleep for more hours, you allow your brain to spend more time relaxing.
As you reduce the sleep debt, your body will come to rest at a sleeping pattern that is specifically right for you. Sleep researcher believe that genes determine our individual sleeping patterns. So you can’t train yourself to be a “short sleeper”. A 2005 study in the journal Sleep found that the more tired we get, the less tired we feel.
46. Which of the following is NOT the side effect of sleep debt?
A. Putting on weight. B. Having a bad memory.
C. Having trouble eating food. D. A temporary loss of eyesight.
47. We learn from the 2007 survey that _______.
A. Americans generally don’t have enough sleep
B. Americans sleep too much over the weekends
C. everyone is supposed to sleep for eight hours
D. most people lack two weeks of sleep every year
48. What should we do to make up for the sleep shortage?
A. We should go to sleep when we are free.
B. We should sleep for at least ten hours every day.
C. We should sleep for one or two more hours at night.
D. We should sleep day and night during the holidays.
49. Why is the intensity of the sleep important to us?
A. Our brain is resting when we are sleeping deeply.
B. Deep sleep helps our brain to fully recover.
C. We feel more relaxed when sleeping soundly.
D. Short sleep makes our body more refreshing.
50. The author seems to believe that _________.
A. the more tired we are getting, the more sleep we need
B. the sleeping patterns have nothing to do with our genes
C. it is possible for us to reduce our sleep time by training
D. it is wise for us to adapt to our natural sleeping patterns.

For many people, there is only one good reason to go to an amusement park: the roller coaster. But why do People go on roller coasters?
"Where else in the world can you scream at the top of your lungs and throw your arms in the air?" Frank Farley asks. "If you did that in most other places, they"d take you to your parents and probably put you through a psychological evaluation (心理检查)." Farley is a psychologist at Temple University in Philadelphia, Pennsylvania.
Roller coasters are often attractive to kids whose lives are stressful or controlled. "Roller coasters are a way of breaking out of the humdrum (单调 ) of everyday life. You can let it all go and scream and shout or do whatever you want," Farley says. It has been proved that many adults feel the same way.
Compared with skateboarding, extreme mountain biking, and other adventure sports, riding roller coasters is safe. Parents usually don"t mind when kids go on coasters. Roller coasters also have a way of bringing people together. Riders share the thrill and adventure of surviving what feels like an extreme experience.
Whether you like to ride a roller coaster may depend on your personality. Psychologists say that there is a certain type of person that naturally seeks out extreme experiences. "They enjoy things like change, variety, and intensity (强度)," says Farley. "These people are actually attracted to thrills." He describes such people as having Type-T personalities ("T" stands for thrill).
He also believes that these thrill seekers are more adventurous and creative than other people. Albert Einstein was a Type T. "If nobody liked to seek stimulation (刺激)," he argues, "the human race wouldn"t be where it is today."
1. What is the passage mainly about?

A. The disadvantages of roller coasters.
B. The characteristics of roller coasters.
C. Why many people enjoy roller coasters.
D. How people act when riding roller coasters.
2. According to Farley, what will most people feel after riding a roller coaster?
A. Scared. B. Confident. C. Nervous. D. Relaxed.
3. If a person is a Type T, he seems to .

A. enjoy adventure sports
B. dislike riding roller coasters
C. like popular sports
D. work well with others
4. According to Farley, to our society, people with Type-T personalities are __
A. dangerous B. important C. useless D. harmful
