         Geography is the study of Earth and its climates. Scientists use it to study global (全球的) warming and
     track (跟踪) 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 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 (细致的) views of Earth from space.
     The pictures were so precise (精确) 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
     响) 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

    What are you going to do if you are in a burning house? How will you escape（逃跑）? Do you know how to save yourself? Please read the following passage.

    Escaping a fire is a serious matter. Knowing what to do during a fire can save yourself. It is important to know the ways you can use and to show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.

    From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving through windows with the least chance of serious injury (伤害).

    The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.

    Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.

    On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Bushes and grass can help to break a fall.

    1.It is important to ____________________.

    A. know the ways to escape a fire      

    B. put out a fire in a burning house

    C. jump out of a burning house           

    D. keep the door closed

    2.It is possible to escape through the windows ___________________.

    A. if you are strong enough                         

    B. if there are some bushes on the ground

    C. if you live on a lower floor                         

    D. if you have a long rope

    3.Keep your head low at the window so that ___________ if the building is on fire.

    A. you can get fresh air                   B. you can call for help

    C. you can easily jump off                  D. you can be seen first

    4.The best title for the passage is _____________.

    A. Escaping as fast as possible              

    B. Saving Yourself from a Burning House

    C. Knowledge on Fire                       

    D. Waiting for Help
