When I was studying in England 10 years ago

When I was studying in England 10 years ago, it (1. be)………….…… very expensive to make long-distance telephone calls. That is why I (2.call)…………..…………….. home to talk to my parents only on special occasions. But today communication has much easier. Emails, video chatting, and video conferencing (3. help)…………….…. millions of people to connect to each other in such a quick and cheap way. Now, from Sweden we (4. use)…………..……… Skype to ‘meet’ our parents every week. In 15 years I think I ( 5. communicate)………………. with my children by telepathy and holography when they study away from home.
