Many of the most damaging and life threatening types of weather, such as torrential rains and severe thunderstorms, begin quickly, strike suddenly, and disappear rapidly, de-stroying small regions while leaving neighboring areas untouched. (79) Conventional (普通) computer models of the atmosphere have limited value in predicting short-lived local storms because the available weather data are generally not detailed enough to allow com-puters to see clearly the small atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at location typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large re-gions than they do forecasting specific local events.
Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or "nowcasts",

The Day a Language Died
When Carios Westez died at the age of 76,a language died,too.Westez,more commonly known as
Red Thunder Cloud,was the last speaker of the Native American language,Catawba.Anyone who wants to hear various songs of the Catawba can contact the Smithsonian Institution in Washington,
D.
C.,where,back in the 1940s,Red Thunder Cloud recorded a series of songs for future generations.______(46)They are all that is left of the Catawba language.The language that.people used to speak is gone forever.
We are all aware of the damage that modern industry can do to the world's ecology(生态).However, few people are aware of the impact that widely spoken languages have on other languages and ways of life. English has spread all over the world.Chinese,Spanish,Russian,and Hindi have become powerful langua- ges,as well.______(47)When this happens,hundreds of languages that are spoken by only a few peo- pie die out.
Scholars believe there are about 6,000 languages around the world,but more than half of them could die out within the next 100 years.There are many examples.Araki is a native language of the island of Vanuatu,located in the Pacific Ocean.It is spoken by only a few older adults,so like Catawba,Araki will soon disappear.Many languages of Ethiopia will have the same fate because each one has only a few speakers.______(48)In the Americas,100 languages,each of which has fewer than 300 speakers,also are dying out.
Red Thunder Cloud was one of the first to recognize the threat of language death and to try to do some-thing about it.He was not actually born into the Catawba.tribe,and the language was not his mother tongue.______(49)The songs he sang for the Smithsonian Institution helped to make Native American music popular.Now he is gone,and the language is dead.
What does it mean when a language disappears?When a plant or insect or animal species dies,it is easy to understand what we've lost and to appreciate what this means for the balance of the natural world.
However,language is only a product of the mind.To be the last remaining speaker of a language,like Red Thunder Cloud,must be a lonely destiny,almost as strange and terrible as being the last surviving member of a dying species.______(50)
______(49)
A.As these languages become more powerful,their use as tools of business and culture increases.
B.For the rest of us,when a language dies,we lose the possibility of a unique way of seeing and describing the world.
C.These languages don't have many native speakers.
D.However,he was a frequent visitor to the Catawba reservation in South Carolina,where he learned the language.
E.Papua New Guinea is an extremely rich source of different languages,but more than 100 of them are ir danger of extinction(灭绝).
F.Some people might want to try to learn some of these songs by heart.
