Prepare well. Determine why the passage was written. Practice reading word groupings, not just individual words. Beware of inserting, skipping over, or substituting words. Observe all punctuation marks.
Pronounce each word correctly. If you do not know how to pronounce a word, look it up in a dictionary, listen to an audio recording of the publication, or ask a good reader for help.
Speak clearly. Enunciate carefully, holding your head high and opening your mouth wide. Make an effort to pronounce each syllable.
