  • [单选题]Passage TwoThe letter you write is your personal representative. It takes your place when circumstances make it impossible for you to be there in person. It goes to the hospital to cheer a sick friend. It goes to your hostess to thank her for entertaining you. It conveys your best wishes, congratulations, condolences--when you are not able to do so in person.
  • A. A friendly letter is like a visit on paper.
