任务型阅读。
     Some people want to be sent into space after their death, others want to lie deep under the sea. But
most people want to go into the freezer (冷藏库). These are believers in cryogenics (低温冷冻学).   
     Now some diseases can't be cured, but they may be cured sometime in the future. So some people
hope that their bodies can be frozen after they die. When a cure is found,warm up his or her body, bring
it back to life and take the cure. Once the body is frozen, it is kept in liquid nitrogen (液态氮) at a
temperature of 328 degrees below zero.   
     Now around a thousand people are going to take cryogenic treatment (处理), though most scientists
say it won't work. If we freeze huge creatures (生物) like humans, every one of their cells (细胞) will be
broken. Can they be brought back to life in the future?
阅读短文,然后根据其内容回答下列问题。

  Photography is about taking photographs. In 1826, a Frenchman named
Niepce needed pictures for his business. But he was not a good artist. 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 photograph.
  The next important date in the history of photograph was 1837. That year,
Daguerre, another Frenchman, took a picture of his studio. He used a new kind of
camera and a different process. In his pictures, you could see everything very
clearly, even the smallest details. This kind of photograph was called a
daguerreotype.Soon, other people began to use Daguerre’s process. Travelers
brought back daguerreotypes from all around the world. People photographed
famous buildings, cities and mountains.
  In about 1840, the process was improved. The photographers could take
pictures of people and moving things. The process was not simple. The
photographers had to carry lots of films and processing equipment(设备). But this
did not stop the photographers, especially in the United States.
  Mathew Brady was a well-known American photographer. He took many
pictures of famous people. The pictures were unusual because they were very
life-like and full of personality. Brady was also the first person to take pictures of
war. His 1862 Civil War pictures showed dead soldiers and destroyed cities.
They made the war seem more real and more terrible.
  In the 1880s, new inventions began to change photograph. Photographers
could buy films readymade in rolls(卷). So they did not have to make the film
themselves. Also, they did not have to process(冲洗) the film at once. They could
bring it back to their studios and develop it later. They did not have to carry lots
of equipment. And finally, the invention of the small hand-held camera made
photography less expensive.
  Photography is also a form of art. Some photographs were not just copies of
the real world. They showed ideas and feelings, like other art forms.
Title: The    1   of Photography
Photography doesn’t only mean taking photographs; it is also a form of art.
Photographs showed not only the real world, but also the ideas and feelings.
In 1826 A Frenchman named Niepce invented a very simple camera and the first

In 1837 A Frenchman named Niepce invented a very simple camera and the first
photograph was    3    by him.

things in the war. He was the first person to take war pictures.
In the
1880s
There were films readymade in rolls(卷). Photographers did not have to
