1.how has the way young people do homework changed over the last ten years? why 2.how has the way we communicate with each other changed overt the last ten to fifteen years? why?

1. In my opinion, the way young people do homework has changed significantly. Nowadays, it takes less time to do homework thanks to the Internet and websites where there is ready homework. Forums can be used to find answers to your questions. 
2. People have stopped writing letters by hand and send them by post. We use skype, email, phones and messangers to stay in touch. People have started seeing eath other less but we use phones more often. Now thanks to cheaper or free communication infrastructure, we can be in touch with realtives and friends who are far away from us.
