WHAT would you do if you were invisible(隐形的)?To many people, this is a fun question.
Do you think this can be true? With recent talks of making invisibility a reality, this fun question could actually become a real problem for people and their governments to consider.
It has recently been reported that researchers in the United States and England are confident that they understand, in theory(理论), how to create an invisibility cloak(斗篷), similar to the one that Harry Potter received from his father. They have already begun to work on it, and are asking for help in developing the material that would be used to create this invisibility cloak.
“Is it science fiction? Well, it’s a theory and that already is not science fiction,” said Professor Sir John Pendry. “It’s possible in theory to do all these Harry Potter things, but we should face the challenge, that is our engineering ability.
“Now, no invisibility cloak has been made yet, but the first testing of invisibility technology could be soon,” said Pendry. “We will have a cloak after not too long.”
Though the idea sounds great, it could be a bad thing if it is used in wars.

It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth. “I’m paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”
It turned out that the woman, Natalie Smith, had read something on a friend’s refrigerator: “Practice random (随意的) kindness and senseless acts of beauty.” The phrase impressed (使某人印象深刻) her so much that she copied it down.
Judy Foreman saw the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she’d taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, saying that though she liked it, she didn’t know where it came from or what it really meant.
Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.
“Here’s the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies include painting the classrooms of shabby schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence (暴力) can build on itself.”
The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been encouraged to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!

Who came up with the phrase according to the passage?
| A．Judy Foreman. | B．Natalie Smith. |

What can we infer from the last paragraph?
| A．People should practice random kindness to those in need. |
| B．People who receive kindness are likely to offer it to others. |
| C．People should practice random kindness to strangers they meet. |
| D．People who receive kindness are likely to pay it back to the giver. |
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.
