Caring for the Elderly
  Thanks to the development of society ,human being'living standard and medical insurance are well improved.Our folk's life has been prolonged. We can see an increasing number of elderly around us .China is just going into an aged society.
  We colledge students are responsible to help the elderly . When we see an old people is acrossing a road ,we  can give an arm to he or she .In a supermarket ,when it is tough for a old person to carry something ,we could help he or she as possible as we can .In our home,we should respect our grandparents,we can read newspapers for our grandparents when it necessary.We may assist the olders who don't have relatives or have relatives far from them.
  Respecting the olders is the virtue of chinese people,we should continue the virtue.The olders made contributions to our society when the were young,now they need helps from society.As the salt of society,we colledge students should be ready to help them!
