Article: Heavy rains have caused disasters across China this summer, bringing the worst landslides in decades. The most deadly disaster happened on August 8 when a big landslide hit Zhouqu County in Gansu province, killing at least 1,407 people. On August 18, landslides hit Gongshan, a town in northwestern Yunnan. At least 38 people were killed and 54 are missing. Heavy rains also caused landslides in several counties in Sichuan province. People were forced to evacuate  to safe places. Landslides and devastation Landslides take place when dirt and rocks slide down a slope together. Sometimes these landslides are small, and hardly noticeable. Other times however, they can be massive, involving the entire side of a mountain. Landslides can be caused by a number of different things. Often rain, which adds weight to the side of a slope, can cause one. Other times they might be caused by erosion .When a stream slowly removes the base of a slope, it weakens the entire side of the mountain. As a slide moves down a mountain slope, it can pick up great speed and energy. Some slides travel at a speed of 300km an hour. The resulting winds can be so powerful that they are known to strip  the leaves off surrounding trees. Earthquakes and landslides Some experts think the landslides in Sichuan were related to the magnitude-8.0 Wenchuan earthquake on May 12, 2008. The quake has caused a change in the structure of the Earth's surface, making it more likely that land will slide in the rain, according to geologist Xu Qiang of the Chengdu University of Technology. Landslides pose  threats to 140 cities and towns in the country, one quarter of which are in Sichuan, said Wei Fangqiang, a researcher with the Chinese Academy of Sciences. Landslide prevention If you want to avoid being a landslide victim, the easiest thing to do is avoid living on slopes or close to mountains. If you live in a landslide-threatened area, try not to water the slopes if possible. If there are large rocks on the slopes above your house, remove them so that they don't cause damage if they fall. It might also be helpful to plant trees on the slopes. Over time, the tree roots may make the soil firmer.

Article: One day the employees of a large company in St Louis,Missouri returned from their lunch break and were greeted with a sign on the front door. The sign said:"Yesterday the person who has been hindering   your growth in this company passed away. We invite you to join the funeral  in the room that has been prepared in the gym." At first everyone was sad to hear that one of their colleagues had died,but after a while they started getting curious about who this person might be. The excitement grew as the employees arrived at the gym to pay their last respects. Everyone wondered:"Who is this person that was hindering my progress? Well,at least he's no longer here." One by one the employees got closer to the coffin  and when they looked inside it they became speechless. They stood over the coffin,shocked and in silence,as if someone had touched the deepest part of their soul. There was a mirror inside the coffin:Everyone who looked inside it could see himself. There was also a sign next to the mirror that said. "There is only one person who can set limits to your growth:it is YOU." You are the only person who can revolutionize  your life. You are the only person who can influence your happiness,your realization and your success. You are the only person who can help yourself. Your life does not change when your family changes,when your friends change,when your boss changes,and when your company changes. Your life changes when YOU change,when you go beyond your limiting beliefs,when you realize that you are the only one responsible for your life.

Article: In 1826, a French man named Niepce needed pictures for his business. But he was not a good artist. 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 in 1837. That year, Daguerre, 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. Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains. 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 films 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. Photography also became one kind of art by the end of the 19thcentury. Some photos were not just copies of the real world. They showed our feelings, like other kinds of art.
