On the other hand, there are also many benefits for reading e-books. I will list two aspects. Most of the e-products are portable, so we can read books anywhere, such as on the subway, bus or the high-speed train. When we have a travel, we can also read many books without taking them. The e-books are also environmentally-friendly. The paper is made from trees, which can prevent the wind and keep the sand. Reading e-books accords with the environmental protection thought and policy. Read more e-books and save more trees.
