Over the last few centuries, there have been many changes in our lives.
To start with, people were not able to travel such a long distance in such a short time in the past. Planes were not very popular at that time because they used to be a very expensive way to travel. Nowadays, we have fast, comfortable vehicles, such as cars and high-speed trains.
Secondly, in the past, people had to work much harder because they did not have the tools that we have today. Today, most of the difficult and dangerous work is done by computers and machines.
Thirdly, in the past, the living conditions were not as good as they are now. There were no bathrooms or running water in many houses, and many people could not buy things like fridges, TV sets or washing machines. Now, most families have several of these things.
Lastly, communications have become much easier than before. In the past, we kept in touch with others by writing letters or sending faxes, but now we have many other ways to choose from, such as making a phone call, sending emails or messages and chatting online. Moreover, we can even see the people whom we care making a phone call with through mobile phones, and we can see each other while chatting online. The most surprising thing is that we can make a phone call with the astronauts and see them when they are in space. What a magical thing!
Thanks to the technology, especially the Internet, our lives have become much easier and happier than before. I'm sure they will become more wonderful in the future. Don't you think so?
