A Letter of Invitation Dear prof. Ellen I am Li Ming, a member of the student union of our college. On behalf of the organization committee, we take great honor in inviting you to act as a judge for the coming English speech contest. The possible work may include assessing the contestants’ performance and give a final score in the aspect of announcement, fluency, content as well as the supplementary gesture. The speech contest will be held in the multi-purpose hall at 2 pm on the May 5th. Please confirm your participation at your earliest convenience.
