以Life in the past and life today写一篇短文

In the past ,the houses were small .There aren't many cars .Many people go for work by bike ,and they often write letters to make friends .The kinds of food are very simple .But now ,the houses are bingger and more comfortable than the past .Cars are more than the past ,so the traffic is crowded .People can send emails or use mobile phone to contact with friends .It's really convenienter than the past .The food also richer and better ,so people can live longer ,have happiness life .
