Question: Article: 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 photo. The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different processs. 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. Travellers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains. In about 1840, the process was improved. Now photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of film and processing equipment. But this did not stop the photographers, especially in the United States, where from the 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. Brady was also the first person 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 film readymade in rolls. So they did not have to make 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 favourite places. They called these pictures "snapshots". 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 drawings. Photography had turned into a form of art by the beginning of the 20th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.

Question: Article: "So?"he said."Er...so what?""So what do you really want to do?"he asked. My father was a lawyer,and I had always assumed he wanted me to go to law school,and follow his path through life."I want to travel,and I want to be a writer."I replied. This was not the answer he would expect."Interesting idea,"he said."I kind of wish I'd done that when I was your age."I wailed. "You have plenty of time.You need to find out what you really enjoy now.Look,it's late. Let's take the boat out tomorrow morning,just you and me. Maybe we can catch some crabs for dinner,and we can talk more." Early next morning we set off along the coast. We didn't talk much,but enjoyed the sound of the seagulls and the sight of the coastline and the sea beyond. There was no surf on the coastal waters at that time."Let's see if we get lucky,"he said,picked up a mesh basket with a rope attached and threw it into the sea. We waited a while,then my father stood up and said,"Give me a hand with this,"and we pulled up the crab cage onto the deck. The cage was filled with dozens of soft shell crabs."Why don't they try to escape?" "just watch them for a moment. Look at that one,there!He's trying to climb out,but every time the other crabs pull him back in,"said my father. After several times,not only did the crab give up its struggle to escape,but it actually began to help stop other crabs trying to escape.He'd finally chosen an easy way of life. Suddenly I understood why my father had suggested catching crabs that morning. He looked at me. "Don't get pulled back by the others,"he said."Spend some time figuring out who you are and what you want in life.Think about what's really important to you,what really interests you,what skills you have.If you can't answer these questions now,then take some time to find out. Because if you don't,you'll never be happy." My father started the motor and we set off back home.
