阅读理解。     Geography is the study of Earth and its climates. Scientists u it to study global (全球的) warming andtrack (跟踪) the weather. Govemments u it to leam where people live and work and to plan what to do withthe land. It is now easier than event. u geography becau of a science called space technology.      The United States launched its first satellite in 1958. Some space missions (使命) that followed weregeographical studies. In fact, earth science is a big part of the work of the National Aeronautics and Space Administration (NASA).      Astronauts looked out of the space shuttle (航天飞机). They decided to take photographs of Earth from their vantage point. Over the years, picture quality improved. Shuttle photography now shows land features,such as rivers. It can even show the streets oflarge cities. Photos of the same places at different times showhow the land is changing.      NASA does not u just photographs, though. In 1958 it launched TIROS (the Television Infrared Obrvation Satellite). This first u of a satellite to study Earth was effective (有效的) in giving weather forecasts. It led to the creation of new space tools to u in geography.      The Landsat Program began in 1972. This satellite nt detailed (细致的) views of Earth from space. Thepictures were so preci (精确) that scientists could count the number and kinds of crops in a field. Landsatshowed where Earth's surface had faults along which earthquakes might happen. This information helped inthe planning of new cities and factories. Landsat also made discoveries. In Antarctica it located ranges of unknown mountains. It pinpointed small lakes in Virginia that were not on maps. Landsat, now more advanced,still flies today.      Another space tool is Earth Obrving - 1 (EO - 1). This spacecraft fiies right behind Landsat. It takes pictures of the same sites. The two ts of pictures, viewed together, show how cities grow and how other places, such as rain forests, become smaller over time. This helps scientists learn how people affect (影响) geography.      One of the newest space tools is the Geographical Information Systems ( GIS). CIS is computer software that helps scientists to study Earth. CIS is different from ear- lier space tools. Business, schools, and even average people-not just the government-can u it to show them how changes in the planet might affect them. 1. Why do govemments study geography according to the passage?  A. To improve the environment. B. To make the land u plan. C. To make new discoveries. D. To count the crops in a field.2. Which of the following is true according to the passage? A. The U. S. satellite program began in 1972. B. Landsat was able to take pictures of other planets. C. TIROS was successful in giving weather forecasts. D. GIS can only be ud by the govemment. 3. EO -1 takes photographs of the same places as Landsat becau  _______.A. the two groups of pictures can show the changes of Earth B. EO - 1 is practicing for future photography missionsC. Landsat is out of date and new pictures are neededD. Landsat can't nd detailed views of Earth from space 4. From the passage, we can infer that _______.A. GIS is the newest computer to study Earth B. NASA only depends on photos to study Earth C. satellite pictures can give more detailed informationsD. recent U. S. satellites are as advanced as the old ones
