The word, “photography”, was first used in 1839. It comes from the Greek words that mean “to write with light”. But photography could only give peoplestatic pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.
Back in 1872, people didn’t know exactly whether all four of a horse’s hooves (蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn’t think so.
At that time, it was hard to know who could win the bet, because a horse’s legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn’t give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence (连续) of 12 photos. One of them clearly showed that all four of the horse’s hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.
Though is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison’s invention.The underlined word“static”in Paragraph 1 most probably means _______.

Turn on the radio. A program will come out from a broadcasting station miles and miles away. We know that sounds and music themselves couldn’t travel that distance through space .There must be something that brings the program from the station. But what is this silent carrier ( 载体) ?
This is known as radio waves. However, we can’t see them or even hear them. In fact, nobody knows exactly what they are. Nevertheless( 然而) ,we know that they are made by electricity .
At the broadcasting station, people talk, sing, play musical instruments or make many other sounds. These sounds are changed into electricity. Then from the broadcasting aerial (天线)of a tall tower , electricity sends out radio waves which travel in all directions .And some of them reach your radio aerial. What happens next is a magical thing. The radio waves start an electric current ( 电流) in your aerial like the one that was first made in the broadcasting station . Finally, the loudspeaker in your radio set changes the electricity into sound .Therefore, you hear the program.

As I stood outside with my two dogs yesterday , it was so cold that my nose and face felt frozen ( 结冰的).
Of course, that doesn’t matter to Ricky and Lucy. They have a habit that they must find a place to fight with each other no matter how cold or hot it is.
As cold as it was, I was excited thinking about how wonderful this special cold really was.
Then the sun broke through the clouds and memories of summer’s really hot days came through my mind. I could remember standing in heat of the afternoon, with sweat pouring down my head and the hot, burning sun against my face. I told myself then and there that in the cold of the winter I would wish I had this heat. Because of the special cold, I enjoy the heat more.
So I realized that without the extremes in my life, I would never appreciate the days
When things just right. without the extremes, life would be boring. For example, heath problems remind us that we need to pay more attention to how we live.
Now, I want to start finding a reason to be happy, even if it’s simply the fact that I’m still alive in the world.
