Famous Inventions and Their Inventors
X-rays were discovered in 1895 by a German professor, Wilhelm Roentgen. People all over the world were amazed by his invention, the X-ray machine. This invention was so important that Roentgen won the first Nobel Prize for Physics in 1901.
The telephone was invented by Alexander Graham Bell, a doctor and speech teacher. The first phone call was made by Bell in 1876. He got acid(酸) on his pants by accident and wanted his partner, Thomas Watson, to help him. The first words spoken on the telephone were “Mr. Watson, come here! I need you!”
Television was invented in 1926 by John Logie Baird, a Scottish inventor. Baird’s television certainly didn't look like a television today! Electronic televisions like the ones we have today were invented by Vladimir Zworykin in the 1920s in the United States.
The first computer was built in 1946 by two American engineers, J. Presper Eckert and John W. Mauchly. It was developed for the army, and it was so large that it took up the whole room! Later, in 1971, the “microchip” was invented, and small home computers were first produced for personal use. Today computers are involved in almost everything we do and are found almost everywhere we go.

Animals, including insects, don't have a "language" like ours. They do not "talk" to each other in words and sentences. But if we watch them, we can see that they do have their ways of communicating with each other.
Can you see the rabbit's tail? When rabbits see this white tail moving up and down, they run away. They know that they are in danger. The rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of "language". When a cobra is angry, it raises its head and makes itself look fierce. This warns other animals. When a bee has found food, it goes back to its home. It cannot "tell" the other bees where the food is by speaking to them, but it does a little dance. This tells the bees where the food is.
Some animals "say" things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs when it is pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sound like "Oh" or "Ah" when we are frightened or pleased or when we drop something on our toes.A rabbit uses its tail to ________.

There was once a young mouse that lived in a hole of a wall. One day, the young mouse woke up (醒来) and looked out of the hole. As he looked out, a fantastic smell came to his nose. “Cheese!” the mouse said happily to himself. “I’ll go and get it now and have it for breakfast.”
But then he remembered his parents’ words. His parents were clever mice and often said to their son. “Always wait before you go for a piece of cheese.”
So the young mouse waited quietly. Then he heard a quiet “Miaow” and he knew the cat was there. He stayed in the hole and said to himself, “I’m glad I listened to my parents and learned to wait.”

“ It’s a dog!” he thought. “If the dog is there, the cat won’t be there. I expect (料想) the dog has chased (追赶) the cat away, so I’m safe.” The mouse ran out of the hole and saw the cat. The cat caught him and ate him.
