查看习题详情和答案>>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 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.
How many kinds of disease is mentioned in the passage?
A.Two B.Three C.Four D.Five
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.
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.
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.
查看习题详情和答案>>People have always been dreaming of going to the moon. As long as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “moon people”. The “moon people” felt even more surprised. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?
1.The explorers in H. G. Well’s story were surprised to find that the “moon people” .
A. knew so much about the earth
B. understood their language
C. lived in underground cities
D. were advanced in technology
2.What does the underlined word “it” (paragraph 2) refer to?
A. Discovering the moon’s inner space
B. Using the earth’s inner space
C. Meeting the “moon people” again
D. Traveling to outer space
3.What sort of underground systems are already in place?
A. Offices, shopping areas, power stations.
B. Tunnels, car parks, shopping areas.
C. Gardens, car parks, power stations.
D. Tunnels, gardens, offices.
4. We can learn from the text that .
A. H. G. Wells once went to moon himself.
B. Underground cities are more comfortable.
C. The solar dome is a necessary part of underground cities.
D. More underground systems will be in place in 2013.
5.What would be the best title of the text?
A. Alice Cities — cities of the future
B. Space travel with H. G. Wells
C. Enjoy living underground
D. Building down, not up
