根据下列材料请回答 31～35 题：
A
Now satellites are helping to forecast the weather．They are in space，and they can reach any part of the world．The satellites take pictures of the atmosphere(大气)，because this is where the weather form．They send these pictures to the weather stations．So meteorologists(气象学家)can see the weather of any part of the world．From the pictures，the scientists can often say how the weather will change．
Today，nearly five hundred weather stations in sixty countries receive satellite pictures．When they receive new pictures，the meteorologists compare them with earlier ones．Perhaps they may find that the clouds have changed during the last few hours．This may mean that the weather on the ground may soon change，too．In their next weather forecast，the meteorologists can say this．
So the weather satellites are a great help to the meteorologists．Before satellites were invented，the scientists could forecast the weather for about 24 0r 48 hours．Now they can make good forecasts for three or five days．Soon，perhaps，they may be able to forecast the weather for a week or more ahead．
第 31 题 Satellites travel______．
A．in space
B．in the atmosphere
C．above the ground
D．above space

Passage Two
The National Weather Service at Ryan Airport brought out the following forecast (预报). Saturday night for Satonp Rouge and vicinity(附近地区).
It will be partly cloudy through Monday with a chance of afternoon showers. High Sunday and Monday will be in the mid 80s,with a low Sunday night in the upper 60s. Winds will be southeasterly 10 to 15 miles per hour diminishing at night.
Probability of rain will be 20 percent Sunday.
On the coast, winds will be southeasterly 10 to 15 knots(节、海里/小时). Seas will run 2-4 feet and will be 3 feet higher near a few thunder-showers. High tide will be at 1 p.m. ,Iow tide at 12:24 a. m..
Record high for May 22 was 93 posted in 1956 and record low was 51 recorded in 1954. Normally, temperatures should be from 86 to 65 degrees.
There will be afternoon thunder-showers Tuesday and over the west part of the state Thursday. Tuesday through Thursday, lows will be in the mid to upper 70s,with highs in the mid to upper 80s.
High Saturday was 86, with a low 65.
40. This weather forecast probably appeared in a______.
A. Saturday morning paper
B. Sunday evening paper
C. Sunday morning paper
D. Monday morning paper

Questions 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 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 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 modem 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 raw 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.

Conventional 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 subtle atmospheric changes that come before these storms.In most nations, for example, weather – balloon observations are taken just once every twelve hours at locations 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 not feasible.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 hard to overcome.Fortunately, scientific and technological advances have overcome most of these problems.Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost.Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information.Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw 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.

D.weather conditions in some small regions are not available
13.According to the passage, the word “Nowcast” (paragraph 3) means _______________.
A.a way of collecting raw weather data
B.a forecast which can predict the weather conditions in the small area in an accurate way
