     Who wants to carry a heavy bag to school? Not children. Nobody wants one shoulder to be lower than the other, and aching too. In India,  most people 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  as  small  as  a  laptop  computer (笔记本电脑) ,  weighing . about 2.5 kg. The goReader has a color screen and can "hold" any textbook that a student may need, says a report in The Asian. Age Newspaper.      

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

     At present, the project is being tested out in a university.  Richard, who founded. the company, is having his invention tested at Chicago's DePaul University, where he studied. Does that mean we will say gooLlbye to the soimd of tuming ne,w paper and the smell of  the black ink?
