　　When a big ship is in very rough(不平坦的) sea, it has to be able to bend(弯) a little, otherwise it may break in two. If one end of the ship is on the top of one huge wave, and the other end is on the top of another, with the middle of the ship hanging in between; or if one huge wave comes up under the middle of the ship, leaving the two ends hanging, the ship's own weight will break its back if it is quite stiff(硬的).

　　To make a big ship elastic(有弹性的) enough to avoid (避开) this danger, it has joints where the sections of the ship come together above the water-line, and these joints (连接处) open and shut slightly as the waves lift one section(部分) of the ship or another. This is enough to save the ship from breaking into pieces.

　　One day a sailor was walking along a passage-way in a big ship during a storm when he was surprised to see a boy sitting comfortably in a chair at the end of the passage-way, which was opposite one of the ship's joints. The boy had a bag of nuts beside him, and every time the ship was lifted by a wave and the joint opened, he put a nut in it. As the ship came down again, the joint closed and cracked(压碎) the nut, gently but firmly. The boy then took it out and put the next one in as the joint opened again.

When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.
Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

Warner Brothers is an American company that produces movies and television shows. It started as a small family business operated by four brothers — Harry, Albert, Sam and Jack Warner. In nineteen-oh-three, the brothers began their business by traveling throughout Ohio and Pennsylvania showing movies using a projector (放映机). By nineteen-oh-seven, they opened a movie theater in New Castle, Pennsylvania. Within ten years, the Warner brothers started producing movies, and moved that part of the business to California.
　　In nineteen eighteen, their first complete picture was called “My Four Years in Germany.” The film was based on a book by the United States’ ambassador to the court of Kaiser Wilhelm. In nineteen twenty-five, they began to work to include the technology for sound in their movies.
　　Two years later, Warner Brothers Pictures released the first major movie with sound, or “talking picture.” It was called “The Jazz Singer” and it was a huge success. In the nineteen thirties, the company made several films that were highly praised, including “Little Caesar,” “The Public Enemy”, “The Gold Diggers” and “Forty-Second Street.”
　　The Warner Brothers’ success continued in the nineteen forties with movies like “The Maltese Falcon,” and “Casablanca.” Movies during this time starred popular actors like Ingrid Bergman, Humphrey Bogart, James Cagney, Gary Cooper and Bette Davis. The company continues to produce popular movies today.
　　By the nineteen seventies, the Warner Brothers studios had also become well set up in television. In nineteen ninety, Warner Communications combined with Time Incorporated to form Time Warner Incorporated.
In two thousand one, the company combined with America Online. The company now includes film production, cable television networks, music and publishing. This year, the company announced a deal with the CBS Corporation to form a new television broadcast network. The CW began broadcasting this month.
