A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words “Post Office” instead of “Post Paid” on the several hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue’s rareness and age, collectors have paid as much as$16 800 for it. 60. Over a century ago, Mauritius ________.

People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a$10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to“speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all! Because of the many changes in computer technology , laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too. (责任编辑：admin) |
