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.

In the United States, children start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they leave secondary（中等的） schools. There are two kinds of schools in the United States: public schools and private（私立的）schools . Most children go to public schools. Their parents do not have to pay for their education because the schools receive money from the government. If a child goes to a private school, his parents have to get enough money for his schooling. Some parents still prefer private schools, though they are much more expensive. Today about half of the high school students go to universities after they finish the secondary school. A student at state university does not have to pay very much if his parents live in that state. But many students work while they are studying at universities. In this way they develop good working habits and live by their own hands.
小题1:Children can go to school at the age of four in the U.S.
