     Laptops are popular all over the world. People use them on trains and airplanes, in airports and hotels. These

laptops connect people to their workplaces. In the United States today, laptops also connect students to their

classrooms.

     West Lake College in Virginia will start a laptop 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 the 510 million computer programs at West Lake, a 110-year-old college. The students with laptops will also

have access (通路) to the Internet. In addition (另外), they will be able to use e-mails 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 is OK!

     Because of many changes in computer technology, laptops are widely used in higher education, such as

colleges and universities. As laptops become more powerful, they become more similar to desktop computers.

In addition, the portable (便携式的) computers can connect students to not only the Internet, but also libraries

and other resources (资源). State higher-education officials are studying how to help students. State officials are

also testing laptop programs at other universities.

     At West Lake College, more than 60 percent of the staff (员工) use computers. The laptops will allow all

teachers to use computers in their lessons. As one West Lake teacher said, here we are in the middle of Virginia

and we're giving students a window of the world. They can see everything and do everything.

根据短文内容，判断正(T)误(F)。

( ) 1. The main purpose of the laptop program is to give each student a laptop to work at home.

( ) 2. West Lake College is an old college in the U.K.

(     ) 3. The laptop program is helpful to the students.

(     ) 4. A window of the world in the last paragraph means that the students can get information from all over

            the world.
