Dear Bob,
Hello.How are you recently?I am writing to tell you that great changes have taken place in my hometown.In the past,few family had a TVset or a telephone but now every family does.There usedn't to be a library but now there is one where people can do some reading in their spare time.No family had a computer before but now many families do.People can get online.Children used to walk far from their houses to school but now they needn't.Many new primary and junior schools whose tuition is free have been built.Children can go to a near school.
Regards
Yours
Wang Hao
