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. In 1902, Willis Carrier invented air conditioning to control the temperature inside his printing company. This saved the paper. People soon realized other benefits of air conditioning. They started to air condition their homes in the summer. Carrier's invention changed the world!

①Have you ever wondered what goes through your mind when you choose where to sit in a new classroom? Or in a waiting room full of strangers? Or on a bus? Researchers have found out some interesting facts.

②Girls sit by girls and boys sit by boys. Adults sit together and young people choose another young person to sit near. But it goes further than this. We even choose to sit near someone who looks like us. People with glasses are more likely to sit near other people with glasses. People with long hair sit closer to other people with long hair.

③We seem to believe that people with similar habits or hobbies will share similar experiences and we are more likely to be accepted by people like ourselves， or even， we think we may be safer with people who look like us. Sometimes that’s true but it’s a pity if we always stay with the same people， the same group. The danger in always staying in our comfort zone (舒适区)is that we just recycle the same opinions， the same tastes and the same ideas. We lose the chance to learn something new， find out interesting things， hear funny stories and discover differences.

④When we always stay with the same people， how can we break down the barriers which prevent us from getting to know people with different ideas? And how can we avoid the ignorance(无知)? If you want to live in a society that opens to changes， new things and different opinions， be the cat among the pigeons(鸽子).

⑤Move out of your comfort zone. Go and sit next to someone different. And don’t just sit there in silence. Say hello. Ask a question. Start a conversation. That’s how we make friends. That’s how we learn about people. That’s how we open our minds to new ideas. That’s how we live an exciting life.
