a letter to the Sunday Mail and express your opinion.3bDear Sir or Madam,I believe that children should do some chores at home.I disagree that childrens only job is to study hard and do well at

with the other parts of the house，but they should try to be responsible for their own areas.This will help them to grow up to be independent and responsible adults.Yours truly，Chen
