The world hasn’t seen a pandemic（流行疾病）in 41 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 SARS 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 experience．

       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．Hospitals will become overcrowded；schools 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．

1．How many kinds of disease is mentioned in the passage?

       A．Two                B．Three               C．Four                  D．Five

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 1N1 flu，SARS is not as infectious．

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．

4．What can be inferred from the passage?

       A．The H1N1 flu will skip from city to city over an 18一to一24 month period．

       B．Doctors and nurses will fall ill themselves，which will result in many more deaths．

       C．Every country is taking measures to stop the H1N1 flu from leading to a pandemic．

       D．The WHO and experts have known much about the current H1N1 flu virus．

American children aren't the only couch potatoes with nearly one third of children globally spending three hours a day or more watching TV or on computers, according to the study of over 70，000 teens in 34 nations.

From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children weren't getting enough exercise and that it made no difference if they lived in a rich or a poor country.“With regards to physical activities levels, we did not find much of a difference between poor and rich countries，” Guthold said.“Growing up in a poor country does not necessarily mean that kids get more physical activities.”The study was published in The Journal of Pediatrics, looking at 72，845 schoolchildren aged 13 to 15 from North and South America, Asia, Europe，and the Middle East. The children were surveyed between 2003 and 2007.

The researchers defined adequate physical activity as at least an hour of exercise outside of gym class at least five days a week. Children who spent three or more hours a day watching TV，playing computer games, or chatting with friends—aside from time in school or time spent doing homework—were classified as sedentary.

The researchers found only one quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30 percent of girls were sedentary and didn't get enough exercise with girls less active than boys in every country aside from Zambia.

Uruguay had the highest percentage of active boys, at 42 percent, while Zambia had the lowest, at 8 percent. Girls from India were the most active, with 37 percent meeting exercise recommendation, while girls from Egypt were the least active, with just 4 percent getting adequate exercise. Children in Myanmar were the least sedentary, with 13 percent of boys and 8 percent of girls classified as sedentary. The most sedentary nations were St. Lucia and the Cayman Islands, with 58 percent of boys and 64 percent of girls spending at least three hours a day in sedentary activities.

People show deep concern for kids' lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated(推测)that urbanization(都市化) could be a factor as well as access to cars and TVs.

16．If you are sedentary, you________．

A．are a diligent student spending much time doing homework

B．have at least an hour of exercise outdoors every day

C．like watching TV and playing computer games

D．spend a lot of time sitting down and not moving

17．Which statement is TRUE about the finding of the study, led by Regina Guthold?

A．Most children around the world don't meet the exercise recommendation.

B．Girls in every country are no more active than boys.

C．Children in rich countries relatively get less physical activities.

D．Only 4 percent of the girls from Egypt are not active in exercise.

18．Which could be the best title of the passage?

A．American children are addicted to TVs and computers

B．Nearly one third of children globally are couch potatoes

C．Effects of physical activities on health

D．Unimaginable standard of physical health

19．What would the writer be most likely to discuss in detail in the following paragraphs?

A．The suitable amount of physical activities for students.

B．Some of the factors for the popularity of cars and TVs among the kids.

C．The reasons behind the lack of physical activities.

D．The ways to make the most of physical activities.

Most people are afraid of bees. Anyone who’s been stung by one quickly learns to avoid bees whenever possible. I learned that lesson when, as a child, I ran into a beehive. Dozens of bees attacked, stinging me all over my body. It was a painful incident, but I was lucky. Those bees weren’t Africanized, or “killer” bees.

Killer bees are extremely aggressive（攻击的）. When they become upset, they attack. And just about anything like noises, shiny objects, dark clothes can all cause killer bees to attack. When one killer bee stings a victim, it gives off a chemical. Other bees smell this and go into attack mode. The whole hive will aggressively attack the unfortunate victim. Killer bees will also run their victims for up to a quarter of a mile. Some victims have tried to keep away from the bees by jumping into water. But killer bees will wait for them to come up and then continue their attack.

Killer bees can be found in South America and the southern United States. They were created when, in 1956, scientists brought African bees to Brazil. African bees were known to increase coffee production. Some scientists thought that these bees might increase honey production, too. So in Brazil, they tried crossbreeding the African bees with European honeybees. The results were disastrous.

The new Africanized bees actually decreased honey production and were very aggressive. Scientists tried to separate the bees, but some of them escaped and began rapidly spreading north. Since then, killer bees have been causing damage to humans, animals and the American honey industry. Over the years, these aggressive killer bees have caused nearly 10,000 people to die.

What’s the best thing to do if you are attacked by killer bees? Fortunately, killer bees don’t fly very fast. Most healthy adults can outrun them. Experts advise you to cover your face and run!

54．Which of the following statements is true according to the passage?

A．It’s a better way to jump into water to escape the attack of killer bees.

B．The Africanized bees did actually increase honey production though aggressive.

C．Killer bees didn’t attack humans, but animals.

D．It is usually not easy for a killer bee to catch up with a healthy adult.

55．The writer refers to his experience of being stung by bees at the first paragraph in order to ___________.

A．prove that bees are dangerous

B．present that killer bees are more dangerous

C．support the idea that people are afraid of bees

D．tell us he had a narrow escape from the attack of bees

56．The underlined word “disastrous” in the third paragraph probably means _________.

A．full of hope                                               B．of no use

C．causing much damage                                D．exciting

57．We can infer from the passage that ___________.

A．killer bees will take the place of European bees before long

B．killer bees are sure to increase the production of coffee

C．it is difficult to get rid of killer bees

D．killer bees have caused great harm to the people there
