　　Who wants to carry a bulky bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining too. In India, most of us would look at the reduction（减少）of textbooks as a way out. But in a country like America, there are always more choices. A company called goReader has created a "school bag" which is the size of a laptop computer, weighing about 2.5 kg. The goReader has a color screen and can "hold" all the textbooks that a student may need, says a report in 'The Asian Age' newspaper.

　　The company plans to work closely with the publishers（出版商） of textbooks so that these books can be supplied on the Internet. All the students will have to do is to download（下载） their textbooks. Making notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before.

At present, the plan is being tested out in a university. Richard Katzmann, the owner of the company is having his creation tested at Chicago's DePaul University, where he studied. Does that mean it is goodbye to the new paper, and the smell of the black ink?
