Who wants to carry a bulky bag to school?No child does. Nobody wants one shoulder to be weighed down (使下沉)and be in pain.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 Go Reader has created a "schoolbag".It is the size of a laptop computer,weighing about 2.5 kg. The Go Reader has a color screen and can "hold"all the textbooks that a student may need.
