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.

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?”? He looked perturbed (不安). “Do you want to try it first?” he said. It didn’t quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it？” This made him look a bit insulted and I started to feel bad. “No, no. But you should try it,” he said encouragingly. “Compare it with the others. ”
I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.
But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out of my chosen camera from cupboard, show how it took excellent pictures of my fellow shoppers… and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.
Why do we think that new options still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.
