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?

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

Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.
Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees) . Trees soak up carbon dioxide, one of the greenhouse gases, from the air.
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that is disappearing because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.
Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (联邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do.
Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.

A.take in B.grow up C.take off D.set up
3.What may be the causes of global warming?
A.The disappearance of plants and animals and the wasting energy.
B.The burning of fossil fuels and storms and floods.
C.The burning of fossil fuels and deforestation.
D.The rising of sea level and deforestation.

The task of fixing climate (气候) change is important. It needs work from different governments and countries. It seems impossible that the common person can make a difference. Should you just give up? No! Change starts with you. Here are just a few things you can do to save the Earth.
Level 1: Things you can do from your sofa ● Save electricity by turning appliances (电器) off completely when they are not in use. ● Stop paper bank bills and pay your bills online. ● Share; don't just like. If you see something interesting on the Internet about climate change, share it so that circle of your friends can see it, too. | |
Level 2: Things you can do at home ● Air dry. Let your hair and clothes dry naturally, instead of using a machine. ● Take short showers. Bathtubs (浴缸) need much more water than a ten-minute shower. ● Recycle paper, plastic and glass. ● Replace old appliances with energy-saving models. | |
Level 3: Things you can do outside your house ● Bike, walk, take a bus or an underground. ● Use a glass or plastic water bottle and china coffee cup. This can cut down on waste and maybe even save your money. ● Bring your own bag when you shop. Pass on the plastic bag. ● Give away what you don't use. Local community will give your used clothes, books and furniture a new life. |

It is well known that Albert Einstein was one of the greatest scientists of all time and he was also a really great person. Here are some interesting things about him.
When Einstein started to work in America, someone asked him what he needed. He said he needed a desk, some paper and a pencil. He also asked for a big waste-paper basket to hold all of his mistakes. This shows that he knew even the cleverest man in the world can only learn by making mistakes.
Einstein regarded time as very important. He never wore socks and he thought putting on socks was a waste of time as people already wore shoes. He also thought it was a waste of time remembering things that could quickly be found in a book. That's why he never remembered his own phone number, which was in the phone book. He knew what was worth remembering. It is true that if we are going to do great things in our lives, we can not waste our time.
Einstein liked to joke too. Once in an exam a student asked him why all the questions were the same as last year's. Einstein replied the questions were the same but the answers were different!

Why do earthquakes happen?Scientists explain that the outside of the earth is made of a number of different plates(板块).For example,at San Francisco the Pacific(太平洋的)Plate which is moving towards the northwest meets the North American Plate. The Pacific Plate is moving very slowly—at 5.3 centimeters a year. Sometimes these two plates stop and do not move for years. Then suddenly,they jump and an earthquake is felt. As a result of the movement of these plates,West America near the sea has always been a bad place for earthquakes. When the 1906 earthquake happened,the Pacific Plate jumped 5-6 meters to the north.
We cannot stop earthquakes,but we can do things to make sure they don't destroy(毁坏)the whole cities. First,it is not a good idea to build houses along the lines,where two of the earth's plates join together. Second,if you think there may be an earthquake,it is better to build houses on rock not on sand. Third,you must make the houses as strong as possible. Weak buildings will fall down in an earthquake,but strong ones may stay up.
1.An earthquake can be felt ______.
A. when two plates push each other B. when one plate becomes a bad place
C. when one plate meets the sea D. when two plates don't move for years
2.An earthquake shook San Francisco in the past because ________.
A. San Francisco stands along between the Pacific Plate and the North American Plate
B. San Francisco stands near the Pacific
C. the plate of San Francisco always moves slowly
D. the city of San Francisco wasn't built very well
3.What can we do to make sure earthquakes don't destroy the whole cities?
①Build houses far from the earthquake lines.
②Build houses on rock not on sand.
③Make the houses as strong as possible.
④Stop weak earthquakes.
A. ①②③ B. ②③④ C. ①③④ D. ①②③④
4.Where can we find the passage?
A. In a history book. B. In a science book.
C. In a tour guide for America. D. In a safety guide for common people.
