A young man went to a car showroom. He was wearing rubber boots and a dirty jacket. He needed a haircut badly and was unshaven. The young man examined an expensive car carefully and then turned to speak to the salesman.
"How much does this car cost?" he asked.
"One thousand two hundred and eighteen pounds," the salesman said.
"I'll have sixteen of them. " the young man said.
The salesman smiled. He found it hard to be polite. "You are joking of course," he said," I'm afraid we can't help you. This car is not for sale. "
The salesman showed his customer the door and the young man left the shop without a word. He went to a showroom on the other side of the street and took a handle of notes out of his pocket and paid for the cars. He explained that the cars were for himself and his colleagues working in a Norwe- gian fishing-boat. "We have all earned a lot of money this season," the man said," and we want to buy cars. "

In most of the United States, students attend classes for 5 days each week. Schools are required to hold classes for about 180 days a year. Recently, schools in some areas of the country have begun experimenting with the new teaching arrangement of holding classes for 4 days a week. Classes would meet either Monday through Thursday, or Tuesday through Friday. Some schools in 12 American states are now using that schedule( 日程安排).
The students still have the same number of total hours in class as before. But they attend school for a longer time on each of the 4 days. In Colorado, schools on the four-day week hold classes for seven-and-one-half hours a day for 144 days. Traditional (传统的)schools meet for 6 hours a day for 180 days.
Many schools on a four-day schedule offer special programs, trips or sports meets on the fifth day. Officials say this gives students even more time in class than on the traditional schedule. Students do not have to miss school to go to the events. They can also go to doctors or deal with other important affairs on the fifth day.
The main reason for shortening the school week is that many small schools can save money by not providing meals or transportation for students on the fifth day. And they say research shows that students are not harmed by shorter week.

Thomas Alva Edison was awarded more patents(专利) on inventions than any other American.
When he died in 1931, Americans wondered how they could best show their respect for him. One suggestion was that the nation observe a minute or two of total black-out. All electric power would be shut off in homes, streets and factories.
Perhaps this suggestion made Americans realize futly what Edison and his inventions meant to them. Electric power was too important to the country. Shutting it off for even a short time would have led to complete confusion. A black-out was out of the question.

The keyboard of a typewriter refers to the set of keys in it. Most typewriters have "qwerty" key-boards. The name comes from the first six letters on the board's second line. The "qwerty" board was set up by C. L. Sholes, who was the first man to make a really good typewriter.
Some letters, such as S and T, are used together a great deal in English. Sholes placed such pairs of letter far apart on his keyboard. This made it harder for typists to learn the keyboard. But it helped keep typewriters from jamming. On early machines the bars holding the letters often caught on each other when moving quickly.
Sholes made the name of his machine easy to type. He placed on the same line all the letters of the word "type" and "writer".
