Using Will and Shall

• You can use shall or will with I and we.
   Example: We shall begin with a talk by our honorable
   speaker.
• In spoken English, the short forms I'll and we'll are
   normally used.
   Example: You'll be free to exchange ideas with the
   professor.
• The negative of shall is shan't (or shall not).
   Example: I shan't (or I won't) be here tomorrow.
• Do not use shall with he/she/it/you/they.
• Note that we use shall (not will) in the questions.
  Shall I ...? and shall we ...? (for offers, suggestions etc.):
  - Shall I attend the reception? (Do you want me to
    attend the reception?)
  - Where shall we go this evening?
