A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.

　　The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.

　　Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.

　　The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.

　　“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.

　　Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.

　　“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.

　　Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.

　　T  Pessimism gurantees chances of survival.he authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.

　　However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.

　　In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple cameras. He put it in a window of his house and took a picture of his yard. That was the first photograph.

　　The next important date in the history! of photography was 1837. That year, Daguerre, another French, 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. Then photographers could take pictures of people and moving things. The process was not simple. The photographers had to cary lots of films and processing equipment. But this did not stop the photographers, especially in the United States. After 1840s daguerreotype artists were popular in most cities.

　　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 （个性）.

　　Brady was also the first preson to take pictures of war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.

　　In the 1880s, new inventions began to change photography... 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 the film immediately. They could bring it back to their studios and develop it later meaning that they did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive.

　　With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favorite places. They called these pictures" snapshot".

　　Photographs became very popular in newspapers in the 1890s. Soon magazines and books also used documentary photographs. These pictures showed true events and people. They were much more real than drawing.

　　Photography also turned into a form of art by the end of the 10th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.
