Emails, etickets and ebooks have played a growing role in our daily life, while paperbased materials, such as traditional books, are suffering a great loss of their readers.　　Some people believe that Ebooks will replace the traditional books eventually because of its obvious advantages. Firstly, they are convenient and accessible. You can read so many kinds of interesting ebooks without paying any money just if you have a puter connecting to the internet. Secondly, reading ebooks has developed into part of our daily life. We can easily get latest headline information just by clicking a mouse gently without hearing noise made by frequently thumbing pages.As far as I’m concerned, I hold/share the same opinion with above persons. Besides the reasons offered by them, Ebooks are so beneficial for forest protection that they are greatly helpful in saving energy and protecting environment. Just as bamboobased books were put an end by history, traditional books will lose its all readers and disappear/vanish in the future.　　Possible version 2：disagree(前兩段同上)As for me, a longtime book worm, it’s not likely/impossible for Ebooks to replace traditional books. There are enough reasons which make traditional books survive. For example, long time of reading Ebooks will do harm to our eyes, and readers will find themselves more accessible to printed materials because of unpopularity of puters and the internet to every corner of our life.　　Possible version 3：coexist (前兩段同上)　　From my perspective, I firmly believe ebooks can not take the traditional books’ place totally. They will unquestionably coexist for a long period. Although the ebooks offer us lots of favor
