题目内容

Prediction(预言) has always been a serious business .In the old days ,astrologers(星占学家) were employed(从事于) to predict the future .Today futurologists(未来学家) make scientificall based predictions which are taken seriously .Basically ,the methods used in the past and those used today are similar.You look at what is happening in the present and then project(设想) into the future.

Take something like the motor-car ,for example .It's obviously wasteful , noisy ,dangerous , etc. So perhaps in the future it will have been replaced by something better. Projecting in the same way we can say that the common cold will have been cured; pollution will be got rid of; Antarctica will have been developed; money will have been replaced by credit cards; floating cities will have been built; the Jupiter(木星) will have been visited ;a cure for cancer will have been discovered .The world's mineral supplies will have been used up ,and so on .But only one thing is really certain：most of us will have been completely forgotten!?

In a natural disaster—a hurricane,flood,tornado,volcanic eruption,or other calamity—minutes and even seconds of warning can be the difference between life and death.Because of this,scientists and government officials are working to use the latest technological advances to predict when and where disasters will happen.They are also studying how best to analyze and communicate this information once it is obtained.The goal is to put technology to effective use in saving lives and property when nature unleashes its power with devastating results.

On September 29,1998,Hurricane Georges made landfall in Biloxi,Mississippi,after devastating Haiti,the Dominican Republic,Puerto Rico,and several islands of the Caribbean with torrential rains and winds up to 160 km/h （100 mph）.Few people lost their lives along the Gulf Coast of the United States,although hundreds died in the Caribbean.

This was a very different outcome from 1900,when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston,Texas,killing at least 6 000 people.Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century—residents of Galveston had no advance warning that a storm was approaching,while residents of Biloxi had been warned days in advance of Georges’s approach,allowing for extensive safety precautions.

At the same time that people in Biloxi were thankful for the advance warning,some residents of New Orleans,Louisiana,120 km to the west,were less satisfied.A day before Georges made landfall,forecasters were predicting that the hurricane had a good chance of striking New Orleans.Because much of New Orleans lies below sea level,the city is at risk for flooding.In addition,because New Orleans has a large population in vulnerable locations,emergency management officials must begin evacuations well before a storm strikes.But evacuation costs money:Businesses close,tourists leave,and citizens take precautionary measures.The mayor of New Orleans estimated that his city’s preparations for Georges cost more than 50 million.After the full fury of Georges missed New Orleans,some residents questioned the value of the hurricane forecasts in the face of such high costs.

The differing views on the early warnings for Hurricane Georges illustrate some of the complexities involved in predicting disasters.Disaster prediction is more than just forecasting the future with advanced technology—it is also a process of providing scientific information to the government officials and other decision makers who must respond to those predictions.

In general,the process has three phases.First,there is the challenge of forecasting the event itself.In the case of Georges,scientists worked to predict the future direction and strength of the hurricane days in advance.

A second important challenge is communicating the forecast to decision－makers.Because forecasts are always uncertain,a central factor in disaster predictions is communicating this uncertainty.Uncertainty is usually described in terms of odds or probabilities,much like daily weather forecasts.The media plays an important role in communicating predictions and their uncertainty to the public.

The third part of the process is the use of predictive information by decision makers.Even the most accurate information is of little value if the decision maker does not use it appropriately,for example in deciding whether to order an evacuation.If there is a breakdown in any of these three phases of prediction,the result is increased danger and a higher risk of loss of life.

The underlined word“calamity”refers to ______.

A.nature                       B.thunderstorms            C.disaster                            D.dangers

According the passage,the purpose of disaster prediction is to______.

A.demonstrate the power of advanced technology

B.bring out the truth between life and death

C.prevent such natural disasters from happening

D.reduce human casualties and loss of property

Which of the following areas suffered the most severe damage?

A.Biloxi,Mississippi.                                        B.Gulf Coast of U. S.

C.Galveston,Texas.                                           D.New Orleans.

If you enjoyed the spring-like sunshine over the weekend and thought the weather has finally turned a corner, you’re sadly mistaken.
Chilly (寒冷的) days and grey clouds are forecast for the week—making it far too early to pack away the winter woollies.
Temperatures will struggle to rise above zero at night and fail to make double figures during the day.
People enjoy the spring sunshine in Sefton Park, Aigburth, Liverpool. Forecasters have predicted a return to chilly weather this week.
Met Office forecaster Charlie said, “It was a nice, dry, bright weekend in many parts and Monday is going to be a similar affair for many.”
“Temperatures will be between 5℃and 8℃, which is below average for the start of spring.”
The sun will disappear from the south of the country after today, with dry but cloudy conditions forecast for tomorrow and Wednesday. 
Wednesday will be warmest of the three, with temperatures peaking at 9℃. But this is still two degrees below the March average for the district.
Overnight, temperatures will drop sharply, with lows of minus 3℃for the next three nights.
“It will generally stay on the cold side of average,” said Mr. Powell.
The March misery comes at the end of the coldest winter for more than 30 years.
Temperatures in December, January and February struggled to stay above zero, with the UK’s average 1.5℃, making it the deepest freeze since 1978—79.
It claimed there was just a one-in-seven chance of a cold December to February.
The agency also sadly predicted a “barbecue summer”, saying it was “quite optimistic” that it would be warmer and drier than average.
Following the two mistakes, the Met Office has dropped its long-range seasonal forecasts and will instead publish a monthly prediction for Britain, updated once a week.
In its defense, it says that while short-term forecasts are extremely accurate, Britain’s size and geographical position makes long-term predictions much more challenging.
It also points out that it gave warning of any heavy falls of snow this winter.
60. According to the passage, the weather on Tuesday in the south might be _______.
A. dry but cloudy  B. sunny but chilly  C. sunny and warm  D. cloudy and chilly
61. Which of the following statements is true according to the passage?
A. British people can put away their winter clothes now.
B. The Met Office has shortened its forecast range.
C. The weather forecast becomes more and more accurate.
D. The agency was quite confident of long-term predictions.
62. Which of the following would be the best title for the passage?
A. The big chill isn’t over yet                     B. A warm spring finally arrives
C. A heavy snow is on the way                 D. The Met Office drops forecasts
63. From the passage, we can conclude ________.
A. the weather report is more and more important
B. British people become worried about bad weather
C. Britain has just experienced a very freezing winter
D. The Met Office can always predict any heavy snow falls accurately


The magnitude 7.9 quake struck Sichuan province on May 12 at around noontime, which may have increased the human death toll because many people were at school, and the school buildings turned out to be not firm enough to collapse because of poor construction. More than 69,000 people have been confirmed dead so far, and more than 374,000 injured, with fears of further disasters because several lakes created by rockfall dams may give way and cause sudden flooding.
Clark Burchfiel, Schlumberger Professor of Geology, and Leigh Royden, professor of geology and geophysics in the Department of Earth, Atmospheric and Planetary Sciences at MIT, have been doing extensive research in that region of China and the Tibetan plateau(高原) for more than two decades, but had found no signs that suggested such a large earthquake might strike the area.
The team operated 25 broadband seismograph (地震仪) stations in this region of western Sichuan for more than a year. "Nobody was thinking there would be a major earthquake in that area," Royden says. "This earthquake was quite unusual, and may have involved a simultaneously（同时发生的） severe break of two separate but neighboring faults," she continued.
The region is extremely unusual geologically, Royden says, because of the very steep slopes at the boundary between the Sichuan Basin to the east and the Tibetan plateau to the west. The altitude rises sharply by about 3,500 meters (more than two miles) over a span of only about 50 kilometers (about 30 miles).
The area where the quake occurred is part of the boundary between two of the Earth's structural plates, where the Indian and Asian plates meet in an ongoing collision that has created the Himalayan mountains and the Tibetan plateau. But in central and eastern Tibet, unlike most other areas of continental collision, much of the movement of crust（地壳） is hidden from view. Instead of thickening the entire crust by folding and faulting, the surface of the eastern Tibetan plateau is not deformed（变形的） and is being lifted upward by thickening of a weak crustal layer more than 15 km below the surface.
60. Why did the school buildings collapse in the earthquake, according to the passage?
A. They had too long a history.
B. They were poorly built.
C. They were crowded with students and teachers.
D. They were damaged by the earthquake.
61. Based on Para. 1, why does the writer think that more people will be killed or injured after 
the earthquake?
A. Because there will be more aftershocks after the major quake.
B. Because more school buildings will collapse after the quake.
C. Because destructive flooding caused by rockfall dams is likely to occur..
D. Because there was not enough medical care for the injured in the area.
62. What can we infer from this passage?
A. There was no prediction that such a large-scale quake might occur there.
B. Researchers had done little research in that area before the earthquake struck it.
C. The 5.12 earthquake was the most destructive in the world.
D. If more research had been done, the destruction could have been avoided.
63. Which one can be used as the best title for this passage?
A. The Great Disasters.
B. The Earthquake was very frightening.
C. The Causes of the earthquake.
D. An Extremely Unusual Earthquake.

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened?  Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower?  Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
【小题1】 The whole passage is mainly about ________________.

A．predictions that have come true.B．predictions that haven’t come true.
C．why predictions don’t come true easily.D．what technology will bring about.

A．predictions needn’t consider people’s practical use of technology.
B．the future isn’t always easy to guess.
C．not all past predictions have come true.
D．many of the high—tech things our parents thought we’d be using by now
simply never appeared.
【小题3】The underlined word “weird” probably means __________.
A．wonderfulB．stupidC．practicalD．strange
【小题4】 What does the author think of the flying car?
A．It is too difficult to imagine.B．It is too crazy an idea.
C．It is likely to be made.D．It is often reported in the news.

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品)  of technological developments in the space.
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.
