Many of the most damaging types of weather begin quickly, strike suddenly, and disappear rapidly, destroying small areas while leaving neighboring areas untouched. Such event as a tornado(龍卷風(fēng)) struck the northeastern part of Edmonton, Alberta, in July 1987. Total damages from the tornado went beyond $250 million, the highest ever for any Canadian storm.
Traditional computer models of the atmosphere have limited value in predicting short-lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the slight atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at places separated by hundreds of miles. With such limited data, traditional forecasting models do a much better job predicting general weather conditions over large areas than they do forecasting specific local events.
Until recently, the observation intensive (十分細致) method needed for exact, very short-range forecasts, or “Nowcasts,” was not possible. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties concerned in rapidly collecting and processing the weather data from such a network were hard to overcome.
Fortunately, scientific and technological advances have overcome most of these problems. Radar(雷達) systems and satellites are all able to make detailed, nearly continuous observation over large areas at a lower cost. Communications satellites can send out data around the world cheaply and immediately, and modern computers can quickly collect and analyze this large amount of weather information.
Meteorologists(氣象學(xué)者) and computer scientists now work together to design computer programs and video equipment able to change weather data into words and graphic displays(圖解) that forecasters can understand easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.
Why can’t traditional computer models predict short-lived local storms?
A.The weather data people collect are often wrong.
B.Detailed weather data in some small areas are not available.
C.The computers are not advanced enough to predict them.
D.The computers are not used to forecast specific local events.
The word “Nowcast” in Paragraph 3 means .
A.a network to collect storm data
B.a way of collecting weather data
C.a more advanced system of weather observation
D.a forecast which can predict weather in the small area
What can make “Nowcasts” a reality according to the passage?
A.Scientific and technological advances. B. Advanced computer programs.
C.Computer scientists. D.Meteorologists.
What does the passage mainly talk about?
A.The advantages of “Nowcatsts”.
B.A tornado in Edmonton, A1bertA.
C.The difficulty in predicting tornado.
D.A great development in weather forecast.

“Racism (種族歧視) is a grown-up disease,” declares the saying on Ruby Bridge’s website along with a photo of Mrs. Bridge today, a 6-year-old girl four decades ago. In the photo, she is walking up the steps of the William Frantz Public School in New Orleans, a little black girl accompanied by two officers who protect her on her way to school.
Her name then was Ruby Nell. It was Nov. 14, 1960. She was the first black child to enroll at this all-white elementary school according to the court order to desegregate in New Orleans schools. Her story is moving -- she was a very courageous child -- and remains a significant proof against intolerance (不寬容) of all kinds. Ruby’s photo brings out another powerful image on her website: Norman Rockwells symbolic painting for Look magazine on Jan. 14, 1964, “The Problem We All Live With.”
Rockwell was an illustrator of exceptional skill and charm. He produced a vast number of unforgettable images over a long career, many of them involving children. His American kids are innocent and appealing, but often, at the same time, decidedly naughty. His method was to photograph his models, and the resulting paintings were photographic． But it is revealing to see how the artist slightly changed facial expressions from photo to oil painting in order to make his paintings communicate with the viewer. Communication, even persuasion, lay at the back of his work; this was art for effect.
“The Problem We All Live With” belongs to Rockwell’s later work, when he began openly showing his strong belief in liberty. This is a highly persuasive image. Before he arrived at the final copy, one sketch (草圖) shows the little girl closer to the two officers following her than to those in front. In the finished picture, the girl seems more determined, independent, and untouched． The unfriendly tomatoes thrown on the wall are behind her now, and she, is completely unaffected．
Ruby Nell was protected by officers on her way to school, because .
A．she was a little fighter against racism
B．she was very young, short and timid
C．she was the first black to study in an all-white school
D．she was chosen by the com t0be’wi’th white children
According to the passage, “The Problem We All Live With” is a(n) .
A．social program for American children
B．famous painting by Norman Rockwell
C．photo displayed on Ruby Bridges’ website
D．exhibition at the Norman Rockwell Museum
The word “desegregate” in paragraph 2 probably means“ ”.
A．fight against the white B．end racial separation
C．struggle for freedom D．stop the black-white conflict
The main topic of this passage is .
A．how Rockwell encouraged Ruby to fight against racism
B．how Ruby won her fight to go to an all-white school
C．how Rockwell expressed his protest in .Iris work
D．how persuasive Rockwell’s earlier work of art is

As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(發(fā)電)and transmission (輸送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.
The 19 th century saw land grants(政府撥地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died.
Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.
So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物種) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects.
The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.
The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.
【小題1】What was the problem caused by the construction of the railways?
| A．Small towns along the railways became abandoned. |
| B．Land in the West was hard to manage. |
| C．Some railroad stops remained underused. |
| D．Land grants went into private hands. |
| A．The use of money and power. |
| B．The transmission of power. |
| C．The conservation of solar energy. |
| D．The selection of an ideal place. |
