【简答题】
Laptop computers are popular all over the world. 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. At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.” 小题1: The main purpose of the laptop program is to give each student a laptop to ________. A.use for their schoolwork B.access the Internet C.work at home D.connect them to libraries 小题2: Why is the word “speak” in the second paragraph in quotation marks(引号)? A.They don’t really talk. B.They use the computer language. C.Laptops have speakers. D.None of the above reasons is correct. 小题3: Which of the following is true about Westlake College? A.All teachers use computers.
