Inventions All Around Us
Every invention has a story. These stories often have a lesson to teach, too. Here are the stories of some everyday household inventions.
Canned Food and the Can Opener—Get It Right!
Peter Durand invented canned food in 1810, but there was a problem. Durand didn't have a good way to open the cans. In 1858, Ezra Warner invented a can opener. It used a piece of metal to cut and remove the top from the can, but it was difficult to use. Finally, in 1870, William Lyman added a wheel to the can opener. The metal went around the top of the can and removed it easily. Finally, people were able to open cans without a lot of work. Canned food was soon popular.
Frozen Food—A Little Good Luck Can Help!
Clarence Birdseye had the chance to go on a trip toe Arctic. When people there caught fish, they put the fish in a container (容器) of ice to freeze it quickly. When people cooked the fish later, it was still good! This gave Birdseye an idea. He thought people could also have this kind of food at home. In 1926, Birdseye invented frozen food. People were able to store food in freezers for a long time.
Air Conditioning—One Answer to Two Problems!
Printing companies make books, so they use a lot of paper. Sometimes, changes in the weather can hurt the paper.

What is a supermarket? In the dictionary, a supermarket is a large self-service department store. Some supermarkets have two floors. When you enter such a supermarket, an elevator will take you to the second floor. Here you can buy things such as CDs, pens, clothes, TVs and refrigerators. After you have collected the things you want to buy on the second floor, you can go downstairs to the first floor where food and drinks are sold. You can also buy fresh fruit, vegetables and meat on this floor.
People like to go shopping in the supermarket. Here are some of the reasons.
First, the prices are reasonable. The prices are lower than in special shops and you can choose whatever you want, without going place to place.
Second, the service is excellent. You can walk around freely and no one will ask you “What can I do for you?” If you can’t find something, just ask a service person and he or she will tell you where it is at once.
Third, the quality is good. If you get home and find the food has gone bad, you can return it and they will say sorry and change it for you.
Nowadays many people don’t have much time to walk from one shop to another, so people choose to go to the supermarket in order to save time and money.
What’s more, if you don’t want to buy anything, you can just come and look around in the supermarket. It’s a good place to have a walk.

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
