One possible version：
Letters ，telephones and e-mails are the most common ways of communication。In my opinion ，however，they all have their own characteristics 。
As we all know ，letteres are used less and less nowadays but are still popular when we need to deal with business affairs or apply for jobs 。sometimes，you can even keep these letters for special reasons。Telephones are used widely around the world 。people who want to share their thoughts and feelings can use telephones to communicate with each other easily and conveniently。But they usually cost a lot of money。E-mails ，I think ，are the best way for people to communicate with each other and most importantly ，it just takes a few seconds to send an e-mail for free。
