In 1826, a Frenchman named Niepce needed pictures for his business. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo.
The next important date in the history of photography (摄影术) was in 1837. That year, Daguere, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.
In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the United States worked so hard.
Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual' because they were very lifelike.
Photographs also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world. They showed feelings like other kinds of art.
The first photo taken by Niepce was a picture of______.
A.his business

NASA's Darrel Williams speaks about the Landsat 7 Project. He said that an eruption caused trees to burn up in a large forest. Fifteen years later, pinkish images from space show that the trees and plant life are growing again. Williams says that clear-cut areas easily show up in the pictures. He wants Americans to look at how much land is being cleared of forests in our country.
Satellites have provided other information about changes on earth. In the past ten years, more than four miles have shrunk from glaciers in Alaska. Landsat 7 received these computer images of Glacier Bay in Alaska.
Hurricanes Floyd and Irene have damaged the coastline in North Carolina. Runoff from farms and silt have gone into the ocean according to satellite images. Loss of trees and forests have caused hotter summers in southern cities such as Atlanta, Georgia.
The Landsat 7 images are like pictures in a photo album. Instead of pictures of the family, the album shows changes around the globe in the past 25 years.
A new satellite, Terra, is going to be launched by NASA soon. It will be more advanced that Landsat 7 and will take important global pictures. Ocean temperatures and energy loss will be provided by Terra daily.
Landsat 7 shows how changes have occurred on land by sending back ______.
A.images taken with a Polaroid camera
B.the latest images taken by a government satellite
C.a television camera
D.astronauts
