参考解析

解析: 本题翻译为:卫星被发射至低轨道上,以用于天气和军事应用。本题考查“lanuch”的用法。Launchon表示“开始,着手”,本题中发射至低轨道,并没有开始的意思。Launch与around、in以及with并不是搭配词组连接,需要根据题意来选择介词。本题是卫星被发射至低轨道上,而并不是在低轨道的周围(around),也不是用(with)低轨道来发射,因此选C。

Now satellites are 36 to forecast(预报)the weather. They are in space, and they can 37 any part of the world. The satellites take pictures of the atmosphere(大气),38 this is where the weather forms(形成). They send these 39 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 40 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 41 . Perhaps they may find that the clouds have changed during the last few hours. This may mean that the 42 on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great 43 to the meteorologists. 44 __satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may 45 forecast the weather for a week or more ahead(提前).36.________________A. help B. to help C. helped D. helping

_________A. satellites B. pictures C. weather D. space

Parts were ordered only as needed, keeping () and overhead low. A、inventoryB、sacrificeC、drippingD、clear-cut

根据下列材料请回答 31~35 题:ANow 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 spaceB.in the atmosphereC.above the groundD.above space

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
