     Geography is the study of Earth and its climates. Scientists use it to study global (全球的) warming and
 track (跟蹤) the weather. Governments use it to learn where people live and work and to plan what to do
  with the land. It is now easier than ever to use geography because of a science called space technology.
     The United States launched its first satellite in 1958. Some space missions (使命) that followed were
  geographical 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 (航天飛機(jī)). 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 of large cities. Photos of the same places at different
 times show how the land is changing.
     NASA does not use just photographs, though. In 1958 it launched TIROS (the Television Infrared
 Observation Satellite). This first use 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 use in geography.
     The Landsat Program began in 1972. This satellite sent detailed (細(xì)致的) views of Earth from space.
 The pictures were so precise (精確) that scientists could count the number and kinds of crops in a field.
 Landsat showed where Earth's surface had faults along which earthquakes might happen. This information
  helped in the 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 Observing-1(EO-1). This spacecraft flies right behind Landsat. It takes
 pictures of the same sites. The two sets 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
 響) geography.
     One of the newest space tools is the Geographical Information Systems(GIS). GIS is computer
 software  that helps scientists to study Earth. GIS is different from earlier space tools. Businesses, schools,
  and even average people--not just the government--can use it to show them how changes in the planet
 might affect them.
1. Why do governments study geography according to the passage?
    A. To improve the environment.
    B. To make the land use 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 used by the government.
3. EO-1 takes photographs of the same places as Landsat because _____.
    A. the two groups of pictures can show the changes of Earth
    B. EO-1 is practicing for future photography missions
    C. Landsat is out of date and new pictures are needed
    D. Landsat can't send 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 information
    D. recent U. S. satellites are as advanced as the old ones

     Eating in space is different from eating on Earth. The food that astronauts carry with them does not look
  like the food you eat.
     Some food is carried in closed bags. It is cooked and frozen (冷凍) before the astronauts get it. All the
  water is removed from the food. In the spaceship, the astronaut puts the water back. He "shoots" hot or
 cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other
 foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs
 (碎屑). Crumbs would float (漂浮) around the spaceship and get in the way. Meat and cake often come
 in bite-size pieces.
     Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is
  put in the special gun. The astronaut shoots the water into his mouth.
     Eating in space is not easy. Astronauts must learn to eat in their way.
1. What is the food carried in closed bags by astronauts like?
    ___________________________________________________________________.
2. How do the astronauts eat food in space?
    ___________________________________________________________________.
3. How do the astronauts drink water in space?
    ___________________________________________________________________.
4. Why can't the astronauts drink water from open cups?
    ___________________________________________________________________.
5. What is the main idea of the passage?
    _______________________________________________________________.
