a. Dear Sir or Madam, I am writing to apply for the post of a volunteer at your charity centre.

b. Actually, last summer, I spent a month there helping to take care of young kids. I am also patient and caring.

c. I look forward to hearing from you. Yours faithfully.

d. I can spend hours listening to and talking with other people. I am available for an interview on any day after 4:30 p.m. If my application is successful, I can start work immediately.

e. I saw the advertisement on my school notice board last week. I have experience in volunteering in my local orphanage.
