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.

High schools have canteens, which serve everything from noodles to rice, but not burgers and chips. Other children bring food from home such as cold rice balls, meat or fish, pickles(泡菜) and vegetables.
Students take home a menu for the coming month containing notes on nutrition value. Twice a year parents are invited to have a taste of the food. The class with the fewest leftovers(剩饭) at the end of the month receives a prize.
United States
A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies. School lunches must also provide at least one-third of the daily dietary allowances(定量) of protein, vitamin A, vitamin C, iron, calcium and calories.
Australia
Meat pies, sausage rolls and hot dogs are all traditional dishes in Australian school shops. But as the nation pays more attention to children’s health, healthier foods have started to find their way onto school menus.

Dear Editor,

I had my ears pierced without asking for permission from my mother, and she is angry with me now. She can’t accept the fact that teenagers get their ears pierced. I think it isn’t a big deal for me to do this. I argued with my mother and we were both unhappy. Can you tell me how to solve this problem?
