The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鸽子). Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way.
Human (人类的) messengers (persons carrying messages) are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system(电子印刷系统) could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each.
Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about the pigeons in the newspapers around the world.

Grandma was always forgetting things." What's wrong with her?" Anna asked. "We think she's getting old, and she may be ill. We may have to send her to a nursing home so that she can be taken good care of. But we can go to see her and bring her presents, like strawberry ice cream." Mother said.
One day, they went to see Grandma at the nursing home. Anna hugged(拥抱) Grandma. "Look," she said, "we've brought you strawberry ice cream!" Grandma didn't say anything. She just took it and began eating. "Do you know who I am?" Anna asked. "You're the girl who brings me ice cream." Grandma said. "Yes, but I'm Anna, your granddaughter. Don't you remember me?" she asked, throwing her arms around the old lady. Grandma smiled, "Remember? Sure. You're the girl who brings me ice cream." Suddenly Anna realized that Grandma would never remember her. "Oh, how I love you, Grandma!" she said. Just then she saw a tear roll down Grandma's cheeks (脸颊).
