单选题Passage3 Questions 11 to 15 are based on the following passage. 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, destroying 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 computers to see clearly the small atmospheric changes that come before these storms.In most nations, for example, weather-balloon observations are taken just once ever3r 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 regions than they do forecasting specific local events. Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or nowcasts, was impracticable. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were beyond overcoming.Fortunately, scientific and technological advance have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communication satellites can transmit data around the world cheaply and immediately, and modern computers can quickly compile and analyze this large volume of weather information. (80) Meteorologists（气象学家）and computer scientists now work together to design computer programs and video equipment capable of transforming r.aw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.12 Nowcasts are_______.Alocal forecastsBshort-range forecastsCmedium-range forecastsDlong-range forecasts

单选题Passage3 Questions 11 to 15 are based on the following passage. When we accept the evidence of our unaided eyes and describe the Sun as a yellow star,we have summed up the most important single fact about it-at this moment in time.It appears probable, however, that sunlight will be the color we know for only a negligibly(微不足道的)small part of the Sun's history. Stars, like individuals, age and change.As we look out into space,we see around us stars at all stages of evolution.There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit; there are scaring ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range.Obviously, thedaylight produced by any star depends on its temperature, today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun's light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves. That yellowhump will shift as the Sun evolves,and the light of the day will change accordingly.(80) It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel-which it is now doing at the spanking rate of half a billion tons a second-it will become steadily colder and redder.14 According to the passage, as the Sun continues to age, what color is it likely to become?AYellow.BViolet.CRed.DWhite.
