Geography is the study of Earth and its climates. Scientists use it to study global warming and track 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 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. 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 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 views of Earth from space. The pictures were so precise 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 no ton 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 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.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

When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!

Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.

Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:

(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.

(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.

(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.

1.If we _____, we may make global warming worse.

A．use less electricity                      B．drive a car on sunlight

C．plant trees                            D．throw away rubbish

2.We may use more electricity by______.

A．turning off lights                        B．shutting down computers

C．turning up CD players                    D．turning off TV

3.______ will make global warming worse.

A．Methane          B．Cans             C．Newspapers       D．Bottles

4.Using less electricity does good to global warming because_______.

A．the less electricity is used, the more greenhouse gases are produced

B．the more electricity is used, the more greenhouse gases are produced

C．more electricity is used, less greenhouse gases are produced

D．less electricity is used, more greenhouse gases are produced

5.Which is the following is NOT TRUE according to the passage?

A．Driving cars on sunlight helps to stop global warming.

B．When cars burn fossil fuels, they produce greenhouse gases.

C．When trees grow, they send carbon dioxide into the air.

D．By planting more trees, we can lower the number of greenhouse gases in the air.
